What to know about DOE's hydrogen hubs

Inflation Reduction Act climate provisions accelerate clean energy, EV tax credits, methane fee, hydrogen incentives, and a green bank, cutting carbon emissions, boosting manufacturing, and advancing environmental justice and net-zero goals through 2030.

Key Points

They are U.S. policies funding clean energy, EV credits, a methane fee, hydrogen, and justice programs to cut emissions.

✅ Up to $7,500 new and $4,000 used EV tax credits with income limits

✅ First federal methane fee to curb oil and gas emissions

✅ $60B for clean energy manufacturing and environmental justice

The Biden administration this year signed a historic climate and tax deal that will funnel billions of dollars into programs designed to speed the country’s clean energy transition, with ways to tap new funding available to households and businesses, and battle climate change.

As the U.S. this year grappled with climate-related disasters from Hurricane Ian in Florida to the Mosquito Fire in California, the Inflation Reduction Act, which contains $369 billion in climate provisions, was a monumental development to mitigate the effects of climate change across the country, with investment incentives viewed as essential to accelerating clean electricity this decade. 

The bill, which President Joe Biden signed into law in August, is the most aggressive climate investment ever taken by Congress and is expected to slash the country’s planet-warming carbon emissions by about 40% this decade and move the country toward a net-zero economy by 2050, aligning with a path to net-zero electricity many analyses lay out.

The IRA’s provisions have major implications for clean energy and manufacturing businesses, climate startups and consumers in the coming years. As 2022 comes to a close, here’s a look back at the key elements in the legislation that climate and clean energy advocates will be monitoring in 2023.

Incentives for electric vehicles
The deal offers a federal tax credit worth up to $7,500 to households that buy new electric vehicles, as well as a used EV credit worth up to $4,000 for vehicles that are at least two years old. Starting Jan. 1, people making $150,000 a year or less, or $300,000 for joint filers, are eligible for the new car credit, while people making $75,000 or less, or $150,000 for joint filers, are eligible for the used car credit.

Despite a rise in EV sales in recent years, the transportation sector is still the country’s largest source of greenhouse gas emissions, with the lack of convenient charging stations being one of the barriers to expansion. The Biden administration has set a goal of 50% electric vehicle sales by 2030, as Canada pursues EV sales regulations alongside broader oil and gas emissions limits.

The IRA limits EV tax credits to vehicles assembled in North America and is intended to wean the U.S. off battery materials from China, which accounts for 70% of the global supply of battery cells for the vehicles. An additional $1 billion in the deal will provide funding for zero-emissions school buses, heavy-duty trucks and public transit buses.

Stephanie Searle, a program director at the nonprofit International Council on Clean Transportation, said the combination of the IRA tax credits and state policies like New York's Green New Deal will bolster EV sales. The agency projects that roughly 50% or more of passenger cars, SUVs and pickups sold in 2030 will be electric. For electric trucks and buses, the number will be 40% or higher, the group said.

In the upcoming year, Searle said the agency is monitoring the Environmental Protection Agency’s plans to propose new greenhouse gas emissions standards for heavy-duty vehicles starting in the 2027 model year.

“With the IRA already promoting electric vehicles, EPA can and should be bold in setting ambitious standards for cars and trucks,” Searle said. “This is one of the Biden administration’s last chances for strong climate action within this term and they should make good use of it.”

Taking aim at methane gas emissions
The package imposes a tax on energy producers that exceed a certain level of methane gas emissions. Polluters pay a penalty of $900 per metric ton of methane emissions emitted in 2024 that surpass federal limits, increasing to $1,500 per metric ton in 2026.

It’s the first time the federal government has imposed a fee on the emission of any greenhouse gas. Global methane emissions are the second-biggest contributor to climate change after carbon dioxide and come primarily from oil and gas extraction, landfills and wastewater and livestock farming.

Methane is a key component of natural gas and is 84 times more potent than carbon dioxide, but doesn’t last as long in the atmosphere. Scientists have contended that limiting methane is needed to avoid the worst consequences of climate change. 

Robert Kleinberg, a researcher at Columbia University’s Center on Global Energy Policy, said the methane emitted by the oil and gas industry each year would be worth about $2 billion if it was instead used to generate electricity or heat homes.

“Reducing methane emissions is the fastest way to moderate climate change. Congress recognized this in passing the IRA,” Kleinberg said. “The methane fee is a draconian tax on methane emitted by the oil and gas industry in 2024 and beyond.”

In addition to the IRA provision on methane, the Biden Interior Department this year proposed rules to curb methane leaks from drilling, which it said will generate $39.8 million a year in royalties for the U.S. and prevent billions of cubic feet of gas from being wasted through venting, flaring and leaks. 

Boosting clean energy manufacturing
The bill provides $60 billion for clean energy manufacturing, including $30 billion for production tax credits to accelerate domestic manufacturing of solar panels, wind turbines, batteries and critical minerals processing, and a $10 billion investment tax credit to manufacturing facilities that are building EVs and clean energy technology, reinforcing the view that decarbonization is irreversible among policymakers.

There’s also $27 billion going toward a green bank called the Greenhouse Gas Reduction Fund, which will provide funding to deploy clean energy across the country, particularly in overburdened communities, and guide utility carbon-free electricity investments at scale. And the bill has a hydrogen production tax credit, which provides hydrogen producers with a credit based on the climate attributes of their production methods.

Emily Kent, the U.S. director of zero-carbon fuels at the Clean Air Task Force, a global climate nonprofit, said the bill’s support for low-emissions hydrogen is particularly notable since it could address sectors like heavy transportation and heavy industry, which are hard to decarbonize.

“U.S. climate policy has taken a major step forward on zero-carbon fuels in the U.S. and globally this year,” Kent said. “We look forward to seeing the impacts of these policies realized as the hydrogen tax credit, along with the hydrogen hubs program, accelerate progress toward creating a global market for zero-carbon fuels.”

The clean energy manufacturing provisions in the IRA will also have major implications for startups in the climate space and the big venture capital firms that back them. Carmichael Roberts, head of investment at Breakthrough Energy Ventures, has said the climate initiatives under the IRA will give private investors more confidence in the climate space and could even lead to the creation of up to 1,000 companies.

“Everybody wants to be part of this,” Roberts told CNBC following the passage of the bill in August. Even before the measure passed, “there was already a big groundswell around climate,” he said.

Investing in communities burdened by pollution
The legislation invests more than $60 billion to address the unequal effects of pollution and climate change on low-income communities and communities of color. The funding includes grants for zero-emissions technology and vehicles, and will help clean up Superfund sites, improve air quality monitoring capacity, and provide money to community-led initiatives through Environmental and Climate Justice block grants.

Research published in the journal Environmental Science and Technology Letters found that communities of color are systematically exposed to higher levels of air pollution than white communities due to redlining, a federal housing discrimination practice. Black Americans are also 75% more likely than white Americans to live near hazardous waste facilities and are three times more likely to die from exposure to pollutants, according to the Clean Air Task Force.

Biden signed an executive order after taking office aimed to prioritize environmental justice and help mitigate pollution in marginalized communities. The administration established the Justice40 Initiative to deliver 40% of the benefits from federal investments in climate change and clean energy to disadvantaged communities. 

More recently, the EPA in September launched an office focused on supporting and delivering grant money from the IRA to these communities.

Cutting ag emissions
The deal includes $20 billion for programs to slash emissions from the agriculture sector, which accounts for more than 10% of U.S. emissions, according to EPA estimates.

The president has pledged to reduce emissions from the agriculture industry in half by 2030. The IRA funds grants for agricultural conservation practices that directly improve soil carbon, as well as projects that help protect forests prone to wildfires.

Separately, this year the U.S. Department of Agriculture announced it will spend $1 billion on projects for farmers, ranchers and forest landowners to use practices that curb emissions or capture and store carbon. That program is focusing on projects for conservation practices including no-till, cover crops and rotational grazing.

Research suggests that removing carbon already in the atmosphere and replenishing soil worldwide could result in a 10% carbon drawdown.

CleanBC Go Electric EV Charger Rebate empowers British Columbia condos, apartments, and workplaces with Level 2 charging infrastructure, ZEV adoption support, and stackable rebates aligned with the CleanBC Roadmap 2030 and municipal top-up incentives.

Key Points

A provincial program funding up to 50% of EV charger costs for condos, apartments, and workplaces across B.C.

✅ Up to 50% back, max $2,000 per eligible Level 2 charger

✅ EV Ready plans fund building upgrades for future charging

✅ Free advisor support: up to 5 hours for condos and workplaces

British Columbians wanting to charge their electric vehicles (EVs) at their condominium building or their place of work can access further funding through EV charger rebates to help buy and install EV chargers through CleanBC’s Go Electric EV Charger Rebate program.

“To better support British Columbians living in condominiums and apartments, we’re offering rebates to make more buildings EV ready,” said Bruce Ralston, Minister of Energy, Mines and Low Carbon Innovation. “With the highest uptake rates of EV adoption in North America, we want to make sure that more people supporting our transition to a low-carbon economy have easy access to charging infrastructure.”

The Province’s CleanBC Go Electric EV Charger Rebate program is receiving $10 million as part of Budget 2021 to help with the upfront costs that come with EVs. Condominiums, apartments and workplaces that purchase and install eligible EV chargers can receive a rebate up to 50% of costs to a maximum of $2,000 per charger. Customers who take advantage of the EV Charger Rebate may have access to top up rebates through participating municipalities and local governments.

“People in British Columbia are switching to electric vehicles in record numbers as part of the transition to a cleaner, better transportation system,” said George Heyman, Minister of Environment and Climate Change Strategy. “We are building on that progress and accelerating positive change through the CleanBC Roadmap. We’re making it more affordable to own an electric vehicle and charging station, with incentives for zero-emission vehicles, so people can improve their driving experience with no air and climate pollution, and lower fuel and maintenance costs overall.”

The strata council for a condo building in Vancouver’s Olympic Village neighbourhood made use of the EV Ready program, as well as new legislation easing strata EV installs and federal support to upgrade their building’s electrical infrastructure. The strata council worked together to first determine, through a load review, if there was enough incoming power to support a level 2 charger for every owner. Once this was determined, the strata’s chosen electrical contractor went to work with the base installation, as well as individual chargers for owners who ordered them. The strata council also ensured a charger was installed in the guest parking.

“The majority of owners in our building came together and gave our strata council approval to make the necessary updates to the building’s infrastructure to support electric vehicle charging where we live,” said Jim Bayles, vice-president of strata council. “While upgrading the electrical and installing the EV chargers was something we were going ahead with anyway, we were pleased to receive quick support from the Province through their CleanBC program as well as from the federal government.”

CleanBC’s EV Ready option supports the adoption of EV infrastructure at apartment and condominium buildings. EV Ready provides rebates for the development of EV Ready plans, a strategy for buildings supported by professionals to retrofit a condo with chargers and make at least one parking space per unit EV ready, and the installation of electrical modifications and upgrades needed to support widespread future access to EV charging for residents.

Up to five hours of free support services from an EV charging station adviser are available through the EV Charger Rebate program for condominiums, apartments and workplaces that need help moving from idea to installation.

Single-family homes, including duplexes and townhouses, can get a rebate of up to 50% of purchase and installation costs of an eligible EV charger to a maximum of $350 through the EV Charger Rebate program.

The Province is providing a range of rebates through its CleanBC Go Electric programs and building out the fast-charging network to ensure the increasing demand for EVs is supported. B.C. has one of the largest public-charging networks in Canada, including the BC's Electric Highway initiative, with more than 2,500 public charging stations throughout the province.

The CleanBC Go Electric EV Charger Rebate program aligns with the recently released CleanBC Roadmap to 2030. Announced on Oct. 25, 2021, the CleanBC Roadmap to 2030 details a range of expanded actions to expand EV charging and accelerate the transition to a net-zero future and achieve B.C.’s legislated greenhouse gas emissions targets.

CleanBC is a pathway to a more prosperous, balanced and sustainable future. It supports government’s commitment to climate action to meet B.C.’s emission targets and build a cleaner, stronger economy for everyone.

Quick Facts:

• The CleanBC Go Electric EV Charger Rebate program provides a convenient single point of service for provincial and any local government rebates.
• EV adviser services for multi-unit residential buildings and workplaces are available through Plug In BC.
• British Columbia is leading the country in transitioning to EVs, even as a B.C. Hydro 'bottleneck' forecast highlights infrastructure needs, with more than 60,000 light-duty EVs on the road.
• British Columbia was the first place in the world to have a 100% ZEV law and is leading North America in uptake rates of EVs at nearly 10% of new sales in 2020 – five years ahead of the original target.
• The CleanBC Roadmap to 2030 commits B.C. to adjusting its ZEV Act to require automakers to meet an escalating annual percentage of new light-duty ZEV sales and leases, reaching 26% of light-duty vehicle sales by 2026, 90% by 2030 and 100% by 2035.

California Gas Car Ban 2035 signals a shift to electric vehicles, raising grid reliability concerns, charging demand, and renewable energy challenges across solar, wind, and storage, amid rolling blackouts and carbon-free power mandates.

Key Points

An order ending new gasoline car sales by 2035 in California, accelerating EV adoption and pressuring the power grid.

✅ 25% EV fleet could add 232.5 GWh/day charging demand by 2040

✅ Solar and wind intermittency strains nighttime home charging

✅ Grid upgrades, storage, and load management become critical

On September 23, California Gov. Gavin Newsom issued an executive order that will ban the sale of gasoline-powered cars in the Golden State by 2035. Ignoring the hard lessons of this past summer, when California’s solar- and wind-reliant electric grid underwent rolling blackouts, Newsom now adds a huge new burden to the grid in the form of electric vehicle charging, underscoring the need for a much bigger grid to meet demand. If California officials follow through and enforce Newsom’s order, the result will be a green new car version of a train wreck.

In parallel, the state is moving on fleet transitions, allowing electric school buses only from 2035, which further adds to charging demand.

Let’s run some numbers. According to Statista, there are more than 15 million vehicles registered in California. Per the U.S. Department of Energy, there are only 256,000 electric vehicles registered in the state—just 1.7 percent of all vehicles, a share that will challenge state power grids as adoption grows.

Using the Tesla Model3 mid-range model as a baseline for an electric car, you’ll need to use about 62 kilowatt-hours (KWh) of power to charge a standard range Model 3 battery to full capacity. It will take about eight hours to fully charge it at home using the standard Tesla NEMA 14-50 charger, a routine that has prompted questions about whether EVs could crash the grid by households statewide.

Now, let’s assume that by 2040, five years after the mandate takes effect, also assuming no major increase in the number of total vehicles, California manages to increase the number of electric vehicles to 25 percent of the total vehicles in the state. If each vehicle needs an average of 62 kilowatt-hours for a full charge, then the total charging power required daily would be 3,750,000 x 62 KWh, which equals 232,500,000 KWh, or 232.5 gigawatt-hours (GWh) daily.

Utility-scale California solar electric generation according to the energy.ca.gov puts utility-scale solar generation at about 30,000 GWh per year currently. Divide that by 365 days and we get 80 GWh/day, predicted to double, to 160 GWh /day. Even if we add homeowner rooftop solar, and falling prices for solar and home batteries in the wake of blackouts, about half the utility-scale, at 40 GWh/day we come up to 200 GW/h per day, still 32 GWh short of the charging demand for a 25% electric car fleet in California. Even if rooftop solar doubles by 2040, we are at break-even, with 240GWh of production during the day.

Bottom-line, under the most optimistic best-case scenario, where solar operates at 100% of rated capacity (it seldom does), it would take every single bit of the 2040 utility-scale solar and rooftop capacity just to charge the cars during the day. That leaves nothing left for air conditioning, appliances, lighting, etc. It would all go to charging the cars, and that’s during the day when solar production peaks.

But there’s a much bigger problem. Even a grade-schooler can figure out that solar energy doesn’t work at night, when most electric vehicles will be charging at homes, even as some officials look to EVs for grid stability through vehicle-to-grid strategies. So, where does Newsom think all this extra electric power is going to come from?

The wind? Wind power lags even further behind solar power. According to energy.gov, as of 2019, California had installed just 5.9 gigawatts of wind power generating capacity. This is because you need large amounts of land for wind farms, and not every place is suitable for high-return wind power.

In 2040, to keep the lights on with 25 percent of all vehicles in California being electric, while maintaining the state mandate requiring all the state’s electricity to come from carbon-free resources by 2045, California would have to blanket the entire state with solar and wind farms. It’s an impossible scenario. And the problem of intermittent power and rolling blackouts would become much worse.

And it isn’t just me saying this. The U.S. Environmental Protection Agency (EPA) agrees. In a letter sent by EPA Administrator Andrew Wheeler to Gavin Newsom on September 28, Wheeler wrote:

“[It] begs the question of how you expect to run an electric car fleet that will come with significant increases in electricity demand, when you can’t even keep the lights on today.

“The truth is that if the state were driving 100 percent electric vehicles today, the state would be dealing with even worse power shortages than the ones that have already caused a series of otherwise preventable environmental and public health consequences.”

California’s green new car wreck looms large on the horizon. Worse, can you imagine electric car owners’ nightmares when California power companies shut off the power for safety reasons during fire season? Try evacuating in your electric car when it has a dead battery.

Gavin Newsom’s “no more gasoline cars sold by 2035” edict isn’t practical, sustainable, or sensible, much like the 2035 EV mandate in Canada has been criticized by some observers. But isn’t that what we’ve come to expect with any and all of these Green New Deal-lite schemes?

US Renewable Energy Capacity 2023 leads new utility-scale additions, with solar, wind, and battery storage surging; EIA data cite tax incentives, lower costs, and smart grid upgrades driving grid reliability and decarbonization.

Key Points

In 2023, renewables dominate new US utility-scale capacity: 54% solar, 7.1 GW wind, 8.6 GW battery storage, per EIA.

✅ 54% of 2023 US additions are solar, a record year

✅ 7.1 GW wind and 8.6 GW batteries expand grid resources

✅ Storage, smart grids, incentives boost reliability and growth

Wind, solar, and batteries make up 82% of 2023’s expected new utility-scale power capacity in the US, highlighting wind power's surge alongside solar and storage, according to the US Energy Information Administration’s (EIA) “Preliminary Monthly Electric Generator Inventory.”

As of January 2023, the US was operating 73.5 gigawatts (GW) of utility-scale solar capacity, which aligns with rising solar generation trends across the US – about 6% of the country’s total.

But solar makes up just over half of new US generating capacity expected to come online in 2023, supported by favourable government plans across key markets. And if it all goes as expected, it will be the most solar capacity added in a single year in the US. It will also be the first year that more than half of US capacity additions are solar, underscoring solar's No. 3 renewable ranking in the U.S. mix.

As of January 2023, 141.3 GW of wind capacity was operating in the US, reflecting wind's status as the most-used renewable nationwide – about 12% of the US total. Another 7.1 GW are planned for 2023. Tax incentives, lower wind turbine construction costs, and new renewable energy targets are spurring the growth. 

And developers also plan to add 8.6 GW of battery storage power capacity to the grid this year, supporting record solar and storage buildouts across the market, and that’s going to double total US battery power capacity.

However, differences in the amount of electricity that different types of power plants can produce mean that wind and solar made up about 17% of the US’s utility-scale capacity in 2021, but produced 12% of electricity, even as renewables surpassed coal nationally in 2022. Solutions such as energy storage, smart grids, and infrastructure development will help bridge that gap.

Canada Renewable Power sees Prairie Provinces surge as Canada Energy Regulator projects rising wind, solar, and hydro capacity in Alberta, Saskatchewan, and Manitoba, replacing coal, expanding the grid, and lowering emissions through 2023.

Key Points

A CER outlook on Canada's grid: Prairie wind, solar, and hydro growth replacing coal and cutting emissions by 2023.

✅ Prairie wind, solar capacity surge by 2023

✅ Alberta, Saskatchewan shift from coal to renewables, gas

✅ Manitoba strengthens hydro leadership, low-carbon grid

Canada's Prairie Provinces will lead the country's growth in renewable energy capacity over the next three years, says a new report by the Canada Energy Regulator (CER).

The online report, titled Canada's Renewable Power, says decreased reliance on coal and substantial increases in wind and solar capacity will increase the amount of renewable energy added to the grid in Alberta and Saskatchewan. Meanwhile, Manitoba will strengthen its position as a prominent hydro producer in Canada. The pace of overall renewable energy growth is expected to slow at the national level between 2021 and 2023, in part due to lagging solar demand in some markets, but with strong growth in provinces with a large reliance on fossil fuel generation.

The report explores electricity generation in Canada and provides a short-term outlook for renewable electricity capacity in each province and territory to 2023. It also features a series of interactive visuals that allow for comparison between regions and highlights the diversity of electricity sources across Canada.

Electricity generation from renewable sources is expected to continue increasing as demand for electricity grows and the country continues its transition to a lower-carbon economy. Canada will see gradual declines in overall carbon emissions from electricity generation largely due to Saskatchewan, Alberta, Nova Scotia and New Brunswick replacing coal with renewables and natural gas. The pace of growth beyond 2023 in renewable power will depend on technological developments; consumer preferences; and government policies and programs.

Canada is a world leader in renewable power, generating almost two-thirds of its electricity from renewables with hydro as the dominant source, and the country ranks in the top 10 for hydropower jobs worldwide. Canada also has one of the world's lowest carbon intensities for electricity.

The CER produces neutral and fact-based energy analysis to inform the energy conversation in Canada. This report is part of a portfolio of publications on energy supply, demand and infrastructure that the CER publishes regularly as part of its ongoing market monitoring.

Report highlights

• Wind capacity in Saskatchewan is projected to triple and nearly double in Alberta between 2020 and 2023 as wind power becomes more competitive in the market. Significant solar capacity growth is also projected, with Alberta adding 1,200 MW by 2023, as Canada approaches a 5 GW solar milestone by that time.
• In Alberta, the share of renewables in the capacity mix is expected to increase from 16% in 2017 to 26% by 2023, with a renewable energy surge supporting thousands of jobs. Similarly, Saskatchewan's renewable share of capacity is expected to increase from 25% in 2018 to 33% in 2023.
• Renewable capacity growth slows most notably in Ontario, where policy changes have scaled back growth projections. Between 2010 and 2017, renewable capacity grew 6.8% per year. Between 2018 and 2023, growth in Ontario slows to 0.4% per year as capacity grows by 466 MW over this period.
• New large-scale hydro, wind, and solar projects will push the share of renewables in Canada's electricity mix from 67% of installed capacity in 2017 to 71% in 2023.
• Hydro is the dominant source of electricity in Canada accounting for 55% of total installed capacity and 59% of generation, though Alberta's limited hydro stands as a notable exception, with B.C., Manitoba, Quebec, Newfoundland and Labrador, and Yukon deriving more than 90% of their power from hydro.
• The jurisdictions with the highest percentage of non-hydro renewable electricity generation are PEI (100%), Nova Scotia (15.8%), and Ontario (10.5%).
• In 2010, 62.8% of Canada's total electricity generation (364 681 GW‧h) was from renewable sources. By 2018, 66.2% (425 722 GW‧h) was from renewable sources and projected to be 71.0% by 2023.

Canadian Electric Bus Fleet leads North America as Toronto's TTC deploys 59 battery-electric, zero-emission buses, advancing public transit decarbonization with charging infrastructure, federal funding, lower maintenance, and lifecycle cost savings for a low-carbon urban future.

Key Points

Canada's leading battery-electric transit push, led by Toronto's TTC, scaling zero-emission buses and charging.

✅ Largest battery-electric bus fleet in North America

✅ TTC trials BYD, New Flyer, Proterra for range and reliability

✅ Charging infrastructure, funding, and specs drive 2040 zero-emissions

The largest battery-powered electric bus fleet in North America is Canadian. Toronto's transit system is now running 59 electric buses from three suppliers, and Edmonton's first electric bus is now on the road as well. And Canadian pioneers such as Toronto offer lessons for other transit systems aiming to transition to greener fleets for the low-carbon economy of the future.

Diesel buses are some of the noisier, more polluting vehicles on urban roads. Going electric could have big benefits, even though 18% of Canada's 2019 electricity from fossil fuels remains a factor.

Emissions reductions are the main reason the federal government aims to add 5,000 electric buses to Canada's transit and school fleets by the end of 2024. New funding announced this week as part of the government's fall fiscal update could also give programs to electrify transit systems a boost.

"You are seeing huge movement towards all-electric," said Bem Case, the Toronto Transit Commission's head of vehicle programs. "I think all of the transit agencies are starting to see what we're seeing ... the broader benefits."

While Vancouver has been running electric trolley buses (more than 200, in fact), many cities (including Vancouver) are now switching their diesel buses to battery-electric buses in Metro Vancouver that don't require overhead wires and can run on regular bus routes.

The TTC got approval from its board to buy its first 30 battery-electric buses in November 2017. Its plan is to have a zero-emissions fleet by 2040.

That's a crucial part of Toronto's plan to meet its 2050 greenhouse gas targets, which requires 100 per cent of vehicles to transition to low-carbon energy by then.

But Case said the transition can't happen overnight. 

Finding the right bus
For one thing, just finding the right bus isn't easy.

"There's no bus, by any manufacturer, that's been in service for the entire life of a bus, which is 12 years," Case said.

"And so really, until then, we don't have enough experience, nor does anyone else in the industry, have enough experience to commit to an all-electric fleet immediately."

In fact, Case said, there are only three manufacturers that make suitable long-range buses — the kind needed in a city the size of Toronto.

Having never bought electric buses before, the city had no specifications for what it needed in an electric bus, so it decided to try all three suppliers: Winnipeg-based New Flyer; BYD, which is headquartered in Shenzhen, China, but built the TTC buses at its Newmarket, Ont. facility; and California-based Proterra.

They all had their strengths and weaknesses, based on their backgrounds as a traditional non-electric bus manufacturer, a battery maker and a vehicle technology and design startup, respectively.

"Each bus type has its own potential challenges." Case said all three manufacturers are working to resolve any adoption challenges as quickly as possible.

But the biggest challenge of all, Case said, is getting the infrastructure in place. 

"There's no playbook, really, for implementing charging infrastructure," he said.

Each bus type needed their own chargers, in some cases using different types of current. Each type has been installed in a different garage in partnership with local utility Toronto Hydro.

Buying and installing them represented about $70 million, or about half the cost of acquiring Toronto's first 60 electric buses. The $140 million project was funded by the federal Public Transit Infrastructure Fund.

Case said it takes about three hours to charge a battery that has been fully depleted. To maximize use of the bus, it's typically put on a long route in the morning, covering 200 to 250 kilometres. Then it's partially charged and put on a shorter run in the late afternoon.

"That way we get as much mileage on the buses as we can."

Cost and reliability?
Besides the infrastructure cost of chargers, each electric bus can cost $200,000 to $500,000 more per bus than an average $750,000 diesel bus. 

Case acknowledges that is "significantly" more expensive, but it is offset by fuel savings over time, as electricity costs are cheaper. Because the electric buses have fewer parts than diesel buses, maintenance costs are also about 25 per cent lower and the buses are expected to be more reliable.

As with many new technologies, the cost of electric buses is also falling over time.

Case expects they will eventually get to the point where the total life-cycle cost of an electric and a diesel bus are comparable, and the electric bus may even save money in the long run.

As of this fall, all but one of the 60 new electric buses have been put into service. The last one is expected to hit the road in early December.

Summer testing showed that air conditioning the buses reduced the battery capacity by about 15 per cent. 

But the TTC needs to see how much of the battery capacity is consumed by heating in winter, at least when the temperature is above 5 C. Below that, a diesel-powered heater kicks in.

Once testing is complete, the TTC plans to develop specifications for its electric bus fleet and order 300 more in 2023, for delivery between 2023 and 2025.

Potential benefits
Even with some diesel heating, the TTC estimates electric buses reduce fuel usage by 70 to 80 per cent. If its whole fleet were switched to electric buses, it could save $50 million to $70 million in fuel a year and 150 tonnes of greenhouse gases per bus per year, or 340,000 tonnes for the entire fleet.

Other than greenhouse gases, electric buses also generate fewer emissions of other pollutants. They're also quieter, creating a more comfortable urban environment for pedestrians and cyclists.

But the benefits could potentially go far beyond the local city.

"If the public agencies start electrifying their fleet and their service is very demanding, I think they'll demonstrate to the broader transportation industry that it is possible," Case said.

"And that's where you'll get the real gains for the environment."

Alex Milovanoff, a postdoctoral researcher in the University of Toronto's department of civil engineering, did a U of T EV study that suggested electrified transit has a crucial role to play in the low-carbon economy of the future.

His calculations show that 90 per cent of U.S. passenger vehicles — 300 million — would need to be electric by 2050 to reach targets under the global Paris Agreement to fight climate change.

And that would put a huge strain on resources, including both the mining of metals, such as lithium and cobalt, that are used in electric vehicle batteries and the electrical grid itself.

A better solution, he showed, was combining the transition to electric vehicles with a reduction in the number of private vehicles, and higher usage of transit, cycling and walking.

"Then that becomes a feasible picture," he said.

What's needed to make the transition
But in order to make that happen, governments need to make investments and navigate the 2035 EV mandate debate on timelines, he added.

That includes subsidies for buying electric buses and building charging stations so transit agencies don't need to make fares too high. But it also includes more general improvements to the range and reliability of transit infrastructure.

"Electrifying the bus fleet is only efficient if we have a large public transit fleet and if we have many buses on the road and if people take them," Milovanoff said.

In its fall economic update on Monday, the federal government announced $150 million over three years to speed up the installation of zero-emission vehicle infrastructure.

Josipa Petrunic, CEO of the Canadian Urban Transit Research and Innovation Consortium, a non-profit organization focused on zero-carbon mobility and transportation, said that in the past, similar funding has paid for high-powered charging systems for transit systems in B.C. and Ontario. But that's only a small part of what's needed, she said.

"Infrastructure Canada needs to come to the table with the cash for the buses and the whole rest of the system."

She said funding is needed for:

Feasibility studies to figure out how many and what kinds of buses are needed for different routes in different transit systems.

Targets and incentives to motivate transit systems to make the switch.

Incentives to encourage Canadian procurement to build the industry in Canada.

Technology to collect and share data on the performance of electric vehicles so transit systems can make the best-possible decisions to meet the needs of their riders.

Petrunic said that a positive side-effect of electrifying transit systems is that the infrastructure can support, in addition to buses, electric trucks for moving freight.

"It's not a lot given that we have 15,000 buses out there in the transit fleet," she said.

"But we should be able to get a lot further ahead if we match the city commitments to zero emissions with federal and provincial funding for jobs creating zero-emissions technologies."
