✅ Inverters manage AC/DC, voltage, and motor speed via frequency

✅ Regenerative braking recovers energy and reduces wear

When was the last time you stopped to think about how electric cars actually work, especially if you're wondering whether to buy an electric car today? We superfans of the car biz have mostly developed a reasonable understanding of how combustion powertrains work. Most of us can visualize fuel and air entering a combustion chamber, exploding, pushing a piston down, and rotating a crankshaft that ultimately turns the wheels. We generally understand the differences between inline, flat, vee-shaped, and maybe even Wankel rotary combustion engines.

Mechanical engineering concepts such as these are comparatively easy to comprehend. But it's probably a fair bet to wager that only a minority of folks reading this can explain on a bar napkin exactly how invisible electrons turn a car's wheels or how a permanent-magnet motor differs from an AC induction one. Electrical engineering can seem like black magic and witchcraft to car nuts, so it's time to demystify this bold new world of electromobility, with the age of electric cars arriving ahead of schedule.

How Electric Cars Work: Motors
It has to do with magnetism and the natural interplay between electric fields and magnetic fields. When an electrical circuit closes allowing electrons to move along a wire, those moving electrons generate an electromagnetic field complete with a north and a south pole. When this happens in the presence of another magnetic field—either from a different batch of speeding electrons or from Wile E. Coyote's giant ACME horseshoe magnet, those opposite poles attract, and like poles repel each other.

Electric motors work by mounting one set of magnets or electromagnets to a shaft and another set to a housing surrounding that shaft. By periodically reversing the polarity (swapping the north and south poles) of one set of electromagnets, the motor leverages these attracting and repelling forces to rotate the shaft, thereby converting electricity into torque and ultimately turning the wheels, in a sector where the electric motor market is growing rapidly worldwide. Conversely—as in the case of regenerative braking—these magnetic/electromagnetic forces can transform motion back into electricity.

How Electric Cars Work: AC Or DC?
The electricity supplied to your home arrives as alternating current (AC), and bidirectional charging means EVs can power homes for days as needed, so-called because the north/south or plus/minus polarity of the power changes (alternates) 60 times per second. (That is, in the United States and other countries operating at 110 volts; countries with a 220-volt standard typically use 50-Hz AC.) Direct current (DC) is what goes into and comes out of the + and - poles of every battery. As noted above, motors require alternating current to spin. Without it, the electromagnetic force would simply lock their north and south poles together. It's the cycle of continually switching north and south that keeps a motor spinning.

Today's electric cars are designed to manage both AC and DC energy on board. The battery stores and dispenses DC current, but again, the motor needs AC. When recharging the battery, and with increasing grid coordination enabling flexibility, the energy comes into the onboard charger as AC current during Level 1 and Level 2 charging and as DC high-voltage current on Level 3 "fast chargers." Sophisticated power electronics (which we will not attempt to explain here) handle the multiple onboard AC/DC conversions while stepping the voltage up and down from 100 to 800 volts of charging power to battery/motor system voltages of 350-800 volts to the many vehicle lighting, infotainment, and chassis functions that require 12-48-volt DC electricity.

How Electric Cars Work: What Types Of Motors?
DC Motor (Brushed): Yes, we just said AC makes the motor go around, and these old-style motors that powered early EVs of the 1900s are no different. DC current from the battery is delivered to the rotor windings via spring-loaded "brushes" of carbon or lead that energize spinning contacts connected to wire windings. Every few degrees of rotation, the brushes energize a new set of contacts; this continually reverses the polarity of the electromagnet on the rotor as the motor shaft turns. (This ring of contacts is known as the commutator).

The housing surrounding the rotor's electromagnetic windings typically features permanent magnets. (A "series DC" or so-called "universal motor" may use an electromagnetic stator.) Advantages are low initial cost, high reliability, and ease of motor control. Varying the voltage regulates the motor's speed, while changing the current controls its torque. Disadvantages include a lower lifespan and the cost of maintaining the brushes and contacts. This motor is seldom used in transportation today, save for some Indian railway locomotives.

Brushless DC Motor (BLDC): The brushes and their maintenance are eliminated by moving the permanent magnets to the rotor, placing the electromagnets on the stator (housing), and using an external motor controller to alternately switch the various field windings from plus to minus, thereby generating the rotating magnetic field.

Advantages are a long lifespan, low maintenance, and high efficiency. Disadvantages are higher initial cost and more complicated motor speed controllers that typically require three Hall-effect sensors to get the stator-winding current phased correctly. That switching of the stator windings can result in "torque ripple"—periodic increases and decreases in the delivered torque. This type of motor is popular for smaller vehicles like electric bikes and scooters, and it's used in some ancillary automotive applications like electric power steering assist.

Permanent-Magnet Synchronous Motor (PMSM): Physically, the BLDC and PMSM motors look nearly identical. Both feature permanent magnets on the rotor and field windings in the stator. The key difference is that instead of using DC current and switching various windings on and off periodically to spin the permanent magnets, the PMSM functions on continuous sinusoidal AC current. This means it suffers no torque ripple and needs only one Hall-effect sensor to determine rotor speed and position, so it's more efficient and quieter.

The word "synchronous" indicates the rotor spins at the same speed as the magnetic field in the windings. Its big advantages are its power density and strong starting torque. A main disadvantage of any motor with spinning permanent magnets is that it creates "back electromotive force" (EMF) when not powered at speed, which causes drag and heat that can demagnetize the motor. This motor type also sees some duty in power steering and brake systems, but it has become the motor design of choice in most of today's battery electric and hybrid vehicles.

Note that most permanent-magnet motors of all kinds orient their north-south axis perpendicular to the output shaft. This generates "radial (magnetic) flux." A new class of "axial flux" motors orients the magnets' N-S axes parallel to the shaft, usually on pairs of discs sandwiching stationary stator windings in between. The compact, high-torque axial flux orientation of these so-called "pancake motors" can be applied to either BLDC or PMSM type motors.

AC Induction: For this motor, we toss out the permanent magnets on the rotor (and their increasingly scarce rare earth materials) and keep the AC current flowing through stator windings as in the PMSM motor above.

Standing in for the magnets is a concept Nikola Tesla patented in 1888: As AC current flows through various windings in the stator, the windings generate a rotating field of magnetic flux. As these magnetic lines pass through perpendicular windings on a rotor, they induce an electric current. This then generates another magnetic force that induces the rotor to turn. Because this force is only induced when the magnetic field lines cross the rotor windings, the rotor will experience no torque or force if it rotates at the same (synchronous) speed as the rotating magnetic field.

This means AC induction motors are inherently asynchronous. Rotor speed is controlled by varying the alternating current's frequency. At light loads, the inverter controlling the motor can reduce voltage to reduce magnetic losses and improve efficiency. Depowering an induction motor during cruising when it isn't needed eliminates the drag created by a permanent-magnet motor, while dual-motor EVs using PMSM motors on both axles must always power all motors. Peak efficiency may be slightly greater for BLDC or PMSM designs, but AC induction motors often achieve higher average efficiency. Another small trade-off is slightly lower starting torque than PMSM. The GM EV1 of the mid-1990s and most Teslas have employed AC Induction motors, despite skepticism about an EV revolution in some quarters.

Reluctance Motor: Think of "reluctance" as magnetic resistance: the degree to which an object opposes magnetic flux. A reluctance motor's stator features multiple electromagnet poles—concentrated windings that form highly localized north or south poles. In a switched reluctance motor (SRM), the rotor is made of soft magnetic material such as laminated silicon steel, with multiple projections designed to interact with the stator's poles. The various electromagnet poles are turned on and off in much the same way the field windings in a BLDC motor are. Using an unequal number of stator and rotor poles ensures some poles are aligned (for minimum reluctance), while others are directly in between opposite poles (maximum reluctance). Switching the stator polarity then pulls the rotor around at an asynchronous speed.

A synchronous reluctance motor (SynRM) doesn't rely on this imbalance in the rotor and stator poles. Rather, SynRM motors feature a more distributed winding fed with a sinusoidal AC current as in a PMSM design, with speed regulated by a variable-frequency drive, and an elaborately shaped rotor with voids shaped like magnetic flux lines to optimize reluctance.

The latest trend is to place small permanent magnets (often simpler ferrite ones) in some of these voids to take advantage of both magnetic and reluctance torque while minimizing cost and the back EMF (or counter-electromotive force) high-speed inefficiencies that permanent-magnet motors suffer.

Advantages include lower cost, simplicity, and high efficiency. Disadvantages can include noise and torque ripple (especially for switched reluctance motors). Toyota introduced an internal permanent-magnet synchronous reluctance motor (IPM SynRM) on the Prius, and Tesla now pairs one such motor with an AC induction motor on its Dual Motor models. Tesla also uses IPM SynRM as the single motor for its rear-drive models.

Electric motors may never sing like a small-block or a flat-plane crank Ferrari. But maybe, a decade or so from now, we'll regard the Tesla Plaid powertrain as fondly as we do those engines, even as industry leaders note that mainstream adoption faces hurdles, and every car lover will be able to describe in intimate detail what kind of motors it uses.

UK Wind Power Leadership in 2020 highlights record renewable energy growth, G20-leading wind share, rapid coal phase-out, and rising solar integration, advancing decarbonization targets under the Paris Agreement and momentum ahead of COP26.

Key Points

The UK led the G20 in wind power share in 2020, displacing coal, expanding solar, and cutting power-sector emissions.

✅ G20-leading wind share; second for combined wind and solar

✅ Fastest coal decline among G20 from 2015 to 2020

✅ Emissions risk rising as post-pandemic demand returns

Nearly a quarter of the UK’s electricity came from wind turbines in 2020 – making the country the leader among the G20 for share of power sourced from the renewable energy, a new analysis finds.

The UK also moved away from coal power at a faster rate than any other G20 country from 2015 to 2020, according to the results.

And it ranked second in the G20, behind Germany, for the proportion of electricity sourced from both wind and solar in 2020, after first surpassing coal in 2016.

“It’s crazy how much wind power has grown in the UK and how much it has offset coal, and how it’s starting to eat at gas,” Dave Jones, Ember’s global lead analyst, told The Independent.

But it is important to bear in mind that “we’re only doing a great job by the standards of the rest of the world”, he added, noting that low-carbon generation stalled in 2019 in the UK.

Ember’s Global Electricity Review notes that the world’s power sector emissions were two per cent higher in 2020 than in 2015 – the year that countries agreed to slash their greenhouse gas pollution as part of the Paris Agreement.

Power generated from coal fell by a record amount from 2019 to 2020, the analysis finds. However, this decline was greatly facilitated by lockdowns introduced to stop the spread of Covid-19, as global electricity demand was temporarily stifled before rebounding, the analysts say.

Coal is the most polluting of the fossil fuels. The UK government hopes to convince all countries to stop building new coal-fired power stations at Cop26, a climate conference that is to be held in Glasgow later this year.

UN chief Antonio Guterres has also called for all countries to end their “deadly addiction to coal”.

At a summit held earlier this month, he described ending the use of coal in electricity generation as the “single most important step” to meeting the Paris Agreement’s goal of limiting global warming to well below 2C above pre-industrial levels by 2100.

“There is definitely a concern that, in the pandemic year of 2020, coal hasn’t fallen as fast as it needed to,” said Mr Jones, even as the UK set coal-free power records recently.

“There is concern that, once electricity demand returns, we won’t be seeing that decline in coal anymore.”

Centrica Dyce Battery Storage will deliver 30MW 2hr capacity in Aberdeenshire, capturing North Sea offshore wind to reduce curtailment, enhance grid flexibility, and strengthen UK energy independence with reliable renewable energy balancing.

Key Points

A 30MW 2hr battery in Dyce, Aberdeenshire, storing North Sea wind to cut curtailment and ease UK grid constraints.

✅ 30MW 2hr system near North Sea offshore wind connection

✅ Cuts curtailment and boosts grid flexibility and reliability

✅ Can power 70,000 homes for an hour with daily cycles

CENTRICA Business Solutions has secured the development rights for a fully consented 30MW 2hr battery storage plant in Aberdeenshire that will help maximise the use of renewable energy in the Scottish North Sea.

The site in Dyce, near Aberdeen is located near a connection for North Sea UK offshore wind farms and will contribute towards managing network constraints – by storing electricity when it is abundant for times when it is not, helping improve the energy independence of the UK and reduce our reliance on fossil fuels. 

Last year, the National Grid paid £244million to wind farm operators to shut down turbines, as they risked overloading the Scottish grid, a process known as curtailment. Battery storage is one method of helping to utilise that wasted energy resource, ensuring fewer green electrons are curtailed. 

Once built, the 30MW 2hr Dyce battery storage plant will store enough energy to power 70,000 homes for an hour. This discharge happens up to four hours per day, as seen in other large-scale deployments like France's largest battery platform that optimise grid balancing.

The project was developed by Cragside Energy Limited, backed by Omni Partners LLP, and obtained planning consent in November 2021. The go-live date for the project is mid-2024, construction should last eight months and will be aligned with the grid connection date.

“Battery storage can play a strategic role in helping to transition away from fossil fuels, by smoothing out the peak demand and troughs associated with renewable energy generation,” said Bill Rees, Director of Centrica Energy Assets. “We should treat renewable energy like a precious resource and projects like this can help to maximise its efficacy.” 

The project forms part of Centrica Energy Assets’ plan to deliver 900MW of solar and battery storage assets by 2026, increasingly paired with solar in global deployments. Centrica already owns and operates the 49MW fast response battery at Roosecote, Cumbria. 

Centrica Business Solutions Managing Director Greg McKenna, said: “Improving the energy independence of the UK is essential to help manage energy costs and move away from fossil fuels. The Government has set a target of a green electricity grid by 2035 – that’s only achievable if we build out the level of flexibility in the system, to help manage supply and demand.”

Centrica Energy Assets will work with Cragside Energy to identify new opportunities in the energy storage space. Cragside Energy’s growing pipeline exceeds 200MW, and focuses on low carbon and flexible assets, including energy storage, solar and peaking plant schemes, supported by falling battery costs across the sector.

Ben Coulston, Director of Cragside Energy, added: “Targeted investment into a complementary mix of diverse energy sources and infrastructure is crucial if the UK is to fully harness its renewable energy potential. Battery storage, such as the project in Dyce, will contribute to the upkeep of a stable and resilient network and we have enjoyed partnering with Centrica as the project transitions into the next phase”.

Ford Oakville Electric Vehicle Complex will anchor EV production in Ontario, adding a battery plant, retooling lines, and assembly capacity for passenger models targeting the North American market and Canada's zero-emission mandates.

Key Points

A retooled Ontario hub for passenger EV production, featuring on-site battery assembly and modernized lines.

✅ Retooling begins Q2 2024; EV production slated for 2025.

✅ New 407,000 sq ft battery plant for pack assembly.

✅ First full-line passenger EV production in Canada.

Ford Motor Co. has revealed some details of its plan to spend $1.8 billion on its Oakville Assembly Complex to turn it into an electric vehicle production hub, a government-backed Oakville EV deal, in the latest commitment by an automaker transitioning towards an electric future.

The automaker said Tuesday that it will start retooling the Ontario complex in the second quarter of 2024, bolstering Ontario's EV jobs boom, and begin producing electric vehicles in 2025.

The transformation of the Oakville site, to be renamed the Oakville Electric Vehicle Complex, will include a new 407,000 square-foot battery plant, similar to Honda's Ontario battery investment efforts, where parts produced at Ford's U.S. operations will be assembled into battery packs.

General Motors is already producing electric delivery vans in Canada, and its Ontario EV plant plans continue to expand, but Ford says this is the first time a full-line automaker has announced plans to produce passenger EVs in Canada for the North American market.

GM said in February it plans to build motors for electric vehicles at its St. Catharines, Ont. propulsion plant, aligning with the Niagara Region battery investment now underway. The motors will go into its BrightDrop electric delivery vans, which it produces in part at its Ingersoll, Ont. plant, as well as its electric pickup trucks, producing enough at the plant for 400,000 vehicles a year.

Ford's announcement is the latest commitment by an automaker transitioning towards an electric future, part of Canada's EV assembly push that is accelerating.

"Canada and the Oakville complex will play a vital role in our Ford Plus transformation," said chief executive Jim Farley in a statement.

The company has committed to invest over US$50 billion in electric vehicles globally and has a target of producing two million EVs a year by the end of 2026 as part of its Ford Plus growth plan, reflecting an EV market inflection point worldwide.

Ford didn't specify in the release which models it planned to build at the Oakville complex, which currently produces the Ford Edge and Lincoln Nautilus.

The company's spending plans were first announced in 2020 as part of union negotiations, with workers seeking long-term production commitments and the Detroit Three automakers eventually agreeing to invest in Canadian operations in concert with spending agreements with the Ontario and federal governments.

The two governments agreed to provide $295 million each in funding to secure the Ford investment.

"The partnership between Ford and Canada helps to position us as a global leader in the EV supply chain for decades to come," said Industry Minister Francois-Philippe Champagne in Ford's news release.

Funding help comes as the federal government moves to require that at least 20 percent of new vehicles sold in Canada will be zero-emission by 2026, at least 60 per cent by 2030, and 100 per cent by 2035.

U.S. Clean Energy Transition accelerates with IRA and BIL, boosting renewable energy, solar PV, battery storage, EV adoption, manufacturing, grid resilience, and jobs while targeting carbon-free electricity by 2035 and net-zero emissions by 2050.

Key Points

U.S. shift to renewables under IRA and BIL scales solar, storage, and EVs toward carbon-free power by 2035.

✅ Renewables reached ~22% of U.S. electricity generation in 2022.

✅ Nearly $13b in PV manufacturing; 94 plants; 25k jobs announced.

✅ Battery storage grew from 3% in 2017 to 36% by H1 2023.

In recent years, the United States has made remarkable strides in embracing renewable energy, with notable solar and wind growth helping to position itself for a more sustainable future. This transition has been driven by a combination of factors, including environmental concerns, economic opportunities, and technological advancements.

With the introduction of the Inflation Reduction Act (IRA) and the Bipartisan Infrastructure Law (BIL), the United States is rapidly advancing its journey towards clean energy solutions.

To underscore the extent of this progress, consider the following vital statistics: In 2022, renewable energy sources (including hydroelectric power) accounted for approximately 22% of the nation's electricity generation, and renewables surpassed coal in the mix that year, while the share of renewables in total electricity generation capacity had risen to around 30% and the nation is moving toward 30% electricity from wind and solar as well.

Notably, in the transportation sector, consumers are increasingly embracing zero-emission fuels, such as electric vehicles. In 2022, battery electric vehicles (BEVs) represented 5.6% of new vehicle registrations, surging to 7.1% by the first half of 2023, according to estimates from EUPD Research.

The United States has set ambitious targets, including achieving 100% carbon pollution-free electricity by 2035 and aiming for economy-wide net-zero greenhouse gas emissions by no later than 2050, and policy proposals such as Biden's solar plan reinforce these goals for the power sector. These targets are poised to provide a significant boost to the clean energy sector in the country, reaffirming its commitment to a sustainable and environmentally responsible future.

IRA and BIL: Catalysts for Growth

The IRA and BIL represent a transformative shift in the landscape of clean energy policy, heralding a new era for the solar and energy storage sectors in the United States. The IRA allocates substantial resources to address the climate crisis, fortify domestic clean energy production, and solidify the U.S. as a global leader in clean energy manufacturing.

According to the U.S. Department of Energy (DOE), an impressive investment exceeding $120 billion has been announced for the U.S. battery manufacturing and supply chain sector since the introduction of IRA and BIL. Additionally, plans have been unveiled for over 200 new or expanded facilities dedicated to minerals, materials processing, and manufacturing. This move is expected to create more than 75,000 potential job opportunities, strengthening the nation's workforce.

Following the introduction of IRA and BIL, solar photovoltaic (PV) manufacturing in the U.S. has also witnessed a substantial surge in planned investments, totaling nearly $13 billion, as reported by the DOE. Furthermore, a total of 94 new and expanded PV manufacturing plants have been announced, potentially generating over 25,000 jobs in the country.

Booming Solar Sector

In recent years, the U.S. solar sector has outpaced other energy sources, including a surging wind sector and natural gas, in terms of capacity growth. EUPD Research estimates reveal a notable upward trend in the contribution of solar capacity to annual power capacity additions, as 82% of the 2023 pipeline consists of wind, solar, and batteries across utility-scale projects. This trajectory has risen from 37% in 2019 to 38% in 2020, further increasing to 44% in 2021 and an impressive 45% in 2022.

Although the country experienced a temporary setback in 2022 due to pandemic-related delays, trade law enforcement, supply chain disruptions, and rising costs, it is now on track to make a historic addition to its PV capacity in 2023. According to EUPD Research's 2023 forecast, the U.S. is poised to achieve its largest-ever expansion in PV capacity, estimated at 32 to 35 GWdc, assuming the installation of all planned utility-scale capacity, and solar generation rose 25% in 2022 as a supportive indicator. Additionally, from 2023 to 2028, the U.S. is projected to add approximately 233 GWdc of PV capacity.

In terms of cumulative installed PV capacity (including utility-scale, commercial and industrial, and residential) on a state-by-state basis, California holds the top position, followed by Texas, Florida, North Carolina, and Arizona. Remarkably, Texas is rapidly expanding its utility-scale PV capacity and may potentially surpass California in the next two years.

Rapid Growth in Battery Storage

Battery energy storage has emerged as the dominant and rapidly expanding source of energy storage in the U.S. in recent years. The proportion of battery storage in the country's energy storage capacity has surged dramatically, increasing from a mere 3% in 2017 to a substantial 36% in the first half of 2023.

Hydrogen vs Battery-Electric Vehicles compare FCEV and BEV tech for range, charging and refueling, zero-emissions, infrastructure in Canada, highlighting urban commuting, heavy-duty use, fast 5-minute fills, 30-minute fast charging, and renewable hydrogen from surplus wind.

Key Points

Hydrogen FCEVs suit long range and heavy-duty use; BEVs excel in urban commutes with overnight charging.

✅ FCEVs refuel in about 5 minutes; ideal for long range and heavy duty.

✅ BEVs fit urban commuting with home or night charging; fewer stops.

✅ Hydrogen enables energy storage from surplus wind and hydro power.

We’re constantly hearing that battery-electric cars are the future, as automakers pursue Canada-U.S. collaboration on EVs across the industry, so I was surprised to see that companies like Toyota, Honda and Hyundai are making hydrogen fuel-cell cars. Which technology is better? Could hydrogen still win? – Pete, Kingston

They’re both in their electric youth, relatively speaking, but the ultimate winner in the race between hydrogen and battery electric will likely be both.

“It’s not really a competition – they’ll both co-exist and there will also be plug-in hydrogen hybrids,” said Walter Merida, director of the Clean Energy Research Centre at the University of British Columbia. “Battery-electric vehicles [BEVs] are better for an urban environment where you have time to recharge and fuel-cell electric vehicles [FCEVs] are better-suited for long range and heavy duty.”

Last year, there were 9,840 BEVs sold in Canada, up from 5,130 the year before. If you include plug-in hybrids, the number sold in 2017 grows to 18,560, though many buyers now face EV shortages and wait times amid high gasoline prices.

And how many hydrogen vehicles were sold in Canada last year?

#google#

None – although Hyundai leased out about a half-dozen hydrogen Tucsons in British Columbia for $599 a month, which included fuel from Powertech labs in Surrey.

In January, Toyota announced it will be selling the Mirai in Quebec later this year. And Hyundai said it will offer about 25 Nexos for sale.

“It’s chicken or egg,” said Michael Fowler, a professor of chemical engineering at the University of Waterloo. “Car manufacturers won’t release cars into the market unless there’s a refuelling station and companies won’t build a refuelling station unless there are cars to fuel.”

Right now, there are no retail hydrogen refuelling stations in Canada. While there are plans under way to add stations in B.C., Ontario and Quebec, we’re still behind Japan, Europe and California, though experts outline how Canada can capitalize on the U.S. EV pivot to accelerate progress.

“In 2007, Ontario had a hydrogen strategy and they were starting to develop hydrogen vehicles and they dropped that in favour of the Green Energy Act and it was a complete disaster,” Fowler said. “The reality is the government of the day listened to the wrong people.”

It’s tough to pinpoint a single reason why governments focused on building charging stations instead of hydrogen stations, Merida said.

“It’s ironic, you know – the fuel cell was invented in Vancouver. Geoffrey Ballard was one of the pioneers of this technology,” Merida said. “And for a while, Canada was a global leader, but eventually government programs were discontinued and that was very disruptive to the sector.”

HYDROGEN FOR THE MASSES?

While we tend to think of BEVs when we think of electric cars, fuel-cell vehicles are electric, too; the hydrogen passes through a fuel cell stack, where it mixes with oxygen from the atmosphere to produce an electric current.

That current powers electric motors to drive the wheels and extra energy goes to a battery pack that’s used to boost acceleration (it’s also charged by regenerative braking).

Except for water that drips out of the hydrogen car, they’re both zero-emission on the road.

But a big advantage for hydrogen is that, if you can find a station, you can pull up to a pump and fill up in five minutes or less – the same way we do now at nearly 12,000 gas stations.

Compare that with fast-charging stations that can charge a battery to 80 per cent in 30 minutes – each station only handles one car at a time. What if you get there and it’s busy – or broken? And right now, there are only 139 of them in Canada.

And at slower, Level 2 stations, cars have to be plugged in for hours to recharge.

In a 2018 KPMG survey of auto executives, 55 per cent said that moves to switch entirely to pure battery-electric vehicles will fail because there won’t be enough charging stations, and some critics argue the 2035 EV mandate is delusional given infrastructure constraints.

“Ontario just invested $20-million in public charging stations and that’s going to service 100 or 200 cars a day,” Fowler said. “If you were to invest that in hydrogen stations, you’d be able to service thousands of cars a day.”

And when you do charge at a station, you might not be using clean power, as 18% of Canada’s 2019 electricity came from fossil fuels according to national data, Fowler said.

“At least in Ontario, in order to charge at a public station during the day, you have to rev up a natural-gas plant somewhere,” Fowler said. “So the only way you’re getting zero emissions is when you can charge at night using excess nuclear, hydro or wind that’s not being used.”

But hydrogen can be made when surplus green energy is stored, Fowler said.

“In Ontario, we have lots of wind in the spring and the fall, when we don’t need the electricity,” he said.

And eventually, you’ll be able to connect your fuel-cell vehicle to the grid and sell the power it produces, Merida said.

“The amount of power generation you have in these moving platforms is quite significant,” Merida said.

There are other strikes against battery-electric, including reduced range by 30 per cent or more in the winter and the need to upgrade infrastructure such as electrical transformers so they can handle more than just a handful of cars on each street charging at night, Fowler said.

In that KPMG survey, executives predicted a nearly equal split between BEVs, FCEVs, hybrids and gasoline engines by 2040.

“Battery-electric vehicles will serve a certain niche – they’ll be small commuter vehicles in certain cities,” Fowler said. “But for the way we use cars today – the family car, the suburban car, buses and probably trucks – it will be the fuel cell.”
