China To Generate Electricity From Compressed Air

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?

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.”

Clean Energy Investment is surging as renewables, electric vehicles, grids, storage, and nuclear outpace fossil fuels, driven by energy security, affordability, and policies like the Inflation Reduction Act, the IEA's World Energy Investment report shows.

Key Points

Investment in renewables, EVs, grids, and storage now surpasses fossil fuels amid cost and security pressures.

✅ $1.7T to clean tech vs just over $1T to fossil fuels this year.

✅ For every $1 in fossil, about $1.7 goes to clean energy.

✅ Solar investment poised to overtake oil production spending.

Investment in clean energy technologies is significantly outpacing spending on fossil fuels as affordability and security concerns, underpinned by analyses showing renewables cheapest new power in many markets, triggered by the global energy crisis strengthen the momentum behind more sustainable options, according to the International Energy Agency's (IEA) latest World Energy Investment report.

About $2.8 trillion (€2.6 trillion) is set to be invested globally in energy this year, of which over $1.7 trillion (€1.59 trillion) is expected to go to clean technologies - including renewables, electric vehicles, nuclear power, grids, storage, low-emissions fuels, efficiency improvements and heat pumps – according to report.

The remainder, slightly more than $1 trillion (€937.7 billion), is going to coal, gas and oil, despite growing calls for a fossil fuel lockdown to meet climate goals.

Annual clean energy investment is expected to rise by 24% between 2021 and 2023, driven by renewables and electric vehicles, with renewables breaking records worldwide over the same period.

But more than 90% of this increase comes from advanced economies and China, which the IEA said presents a serious risk of new dividing lines in global energy if clean energy transitions don’t pick up elsewhere.

“Clean energy is moving fast – faster than many people realise. This is clear in the investment trends, where clean technologies are pulling away from fossil fuels,” said IEA executive director Fatih Birol. “For every dollar invested in fossil fuels, about 1.7 dollars are now going into clean energy. Five years ago, this ratio was one-to-one. One shining example is investment in solar, which is set to overtake the amount of investment going into oil production for the first time.”

Led by solar, low-emissions electricity technologies are expected to account for almost 90% of investment in power generation, reflecting the global renewables share above 30% in electricity markets.

Consumers are also investing in more electrified end-uses. Global heat pump sales have seen double-digit annual growth since 2021. Electric vehicle sales are expected to leap by a third this year after already surging in 2022.

Clean energy investments have been boosted by a variety of factors in recent years, including periods of strong economic growth and volatile fossil fuel prices that raised concerns about energy security, and insights from the IRENA decarbonisation report that underscore broader benefits, especially following Russia’s invasion of Ukraine.

Furthermore, enhanced policy support through major actions like the US Inflation Reduction Act and initiatives in Europe's green surge, Japan, China and elsewhere have played a role.

In Ireland, more than a third of electricity is expected to be green within four years, illustrating national progress.

The biggest shortfalls in clean energy investment are in emerging and developing economies, the IEA added. It pointed to some bright spots, such as dynamic investments in solar in India and in renewables in Brazil and parts of the Middle East. However, investment in many countries is being held back by factors including higher interest rates, unclear policy frameworks and market designs, weak grid infrastructure, financially strained utilities and a high cost of capital.

"Much more needs to be done by the international community, especially to drive investment in lower-income economies, where the private sector has been reluctant to venture," according to the IEA.

Harbour Air Electric Seaplanes pioneer zero-emission aviation with battery-powered de Havilland Beaver flights, pursuing Transport Canada certification for safe, fossil fuel-free service across Vancouver Island routes connecting Vancouver, Victoria, Nanaimo, and beyond.

Key Points

Battery-powered, zero-emission floatplanes by Harbour Air pursuing Transport Canada certification to carry passengers.

✅ 29-minute test flight on battery power alone

✅ New lighter, longer-lasting battery supplier partnership

✅ Aiming to electrify entire 42-aircraft Beaver/Otter fleet

Float plane operator Harbour Air is getting closer to achieving its goal of flying to and from Vancouver Island without fossil fuels, following its first point-to-point electric flight milestone.

A recent flight of the company’s electric de Havilland Beaver test plane saw the aircraft remain aloft for 29 minutes on battery power alone, a sign of an emerging aviation revolution underway.

Harbour Air president Randy Wright says the company has joined with a new battery supplier to provide a lighter and longer-lasting power source, a high-flying example of research investment in the sector.

The company hopes to get Transport Canada certification to start carrying passengers on electric seaplanes by 2023, as projects like the electric-ready Kootenay Lake ferry come online.

"This is all new to Transport, so they've got to make sure it's safe just like our aircraft that are running today,” Wright said Wednesday. “They're working very hard at this to get this certified because it's a first in the world."

Parallel advances in marine electrification, such as electric ships on the B.C. coast, are informing clean-transport goals across the province.

Before the pandemic, Harbour Air flew approximately 30,000 commercial flights annually, along corridors also served by BC Ferries hybrid ships today, between Vancouver, Victoria, Nanaimo, Whistler, Seattle, Tofino, Salt Spring Island, the Sunshine Coast and Comox.

Wright says the company plans to eventually electrify its entire fleet of 42 de Havilland Beaver and Otter aircraft, reflecting a broader shift that includes CIB-backed electric ferries in B.C.

100% Renewable Energy Transition unites solar, wind, hydropower, geothermal, and bioenergy with storage, smart grids, and sector coupling, delivering decarbonization, energy security, and lower LCOE amid post-Fukushima policy shifts and climate resilience goals.

Key Points

It is a pathway using all renewables plus storage and grids to fully decarbonize power, heat, transport, and industry.

✅ Integrates solar, wind, hydro, geothermal, and bioenergy

✅ Uses storage, smart grids, and sector coupling for reliability

✅ Requires enabling policies, finance, and rapid deployment

Renewable energy organizations representing different spheres of the renewable energy community have gathered on the occasion of the tenth anniversary of the Great East Japan Earthquake and Fukushima nuclear accident to emphasize that renewable energies are not only available in abundance, with global renewable power on course to shatter more records, but ready to deliver a renewable world.

The combination of all renewable technologies, be it bioenergy, geothermal energy, hydropower, ocean energy, solar energy or wind power, in particular in combination with storage options, can satisfy all energy needs of mankind, be it for power, heating/cooling, transportation, or industrial processes.

Renewables have seen tremendous growth rates and cost reduction over the past two decades, but there are still many barriers that need to be addressed for a faster renewable energy deployment to eventually achieve global 100% renewable energy, as outlined in an on the road to 100% renewables initiative that charts the path. It is up to political decision-makers to create the legislative and regulatory conditions so that the renewable energy community can act as fast as needed.

Such rapid switch towards renewables is not only a must in light of nuclear risks and the growing threats of climate change, but also the necessary response to the current pandemic situation. And it will allow those hundreds of millions of humans in unserved areas to get for the first time ever access to modern energy services, as noted by a new IRENA report that details how renewables can decarbonise the energy sector and improve lives.

Speakers from the renewable energy community presented today in a joint webinar that a renewable future is a realistic vision, representing:

Energy Watch Group, Global100RE Platform, Global100RE Strategy Group, International Geothermal Association, ISEP Japan, REN Alliance, World Bioenergy Association, World Wind Energy Association.

Dr. Tetsunari Iida, Director of the Institute for Sustainable Energy Policies ISEP Japan:

Ten years ago, on 11 March 2021, the Great East Japan Earthquake and Fukushima Daiichi Nuclear Power Plant accident occurred. It is a "coincidence of global history" that it now coincides with the starting point of the 100% renewable energy initiative that is accelerating around the world.

The world has changed dramatically since 311. Germany, Italy, Switzerland, Taiwan, South Korea, China and many other countries were all shocked by 311 and shifted their focus from nuclear power to renewable energy, and in the U.S. clean energy industries are setting sights on market majority to accelerate this trend. The next ten years will be the decade in which this perception will rapidly become the "new reality". 311 was the "starting point" for a structural energy shift in world history.

Hans-Josef Fell, former MP, President of the Energy Watch Group and co-initiator of the Global100RE Strategy Group:

The disasters of Fukushima and Chernobyl are urging the entire world to quickly end the use of atomic energy, and many call for a fossil fuel lockdown to catalyze a climate revolution alongside the transition. Contrary to what is often claimed, nuclear energy cannot make a contribution to climate protection, but only creates immense problems with toxic radioactivity emissions, nuclear waste, atomic bomb material and the dangers of a nuclear catastrophe. In contrast, 100% renewable energies until 2030 can help achieve climate protection and a simultaneous nuclear phase-out, according to a recently published statement by a world-leading group of energy researchers from the USA, EU and Australia.

Their research suggests that a 100% renewable energy supply, including storage systems, can provide full energy security for all of mankind by 2030 and will even be cheaper than the existing nuclear and fossil energy supply, and with over 30% of global electricity already from renewables, momentum is strong. The only requirement for implementation is the right decisions taken by decision makers both in governments and industry. All technical and economic prerequisites for a disruptive conversion of the global energy supply to 100% renewable energies are already in place.

Hon. Peter Rae AO, President of WWEA and Honorary Chairman of the REN Alliance:

40 years ago, the idea of developing nuclear power appealed to me as a non-polluting method of generating electricity. So I studied it. How to deal with waste and how to ensure it would not create a danger to life. Along came Chernobyl and other accidents. Storage of waste was leaving dangerous hiding places while some waste was alleged to be dumped at sea. I became more and more concerned. There were demonstrations that the existing methods were dangerous and required very strict construction and operational tolerances - up went the cost. Long delays and huge cost increases. I had visited nuclear power stations and talked to expert proponents in UK, France, US, Taiwan and Australia, and debates such as New Zealand's electricity future reflect similar concerns. The more I did the more certain I became that it was not the way to go. Then Fukushima put the dangers and cost beyond doubt.

Let's get on with the rollover to renewables.

Dr. Marit Brommer, Executive Director of the International Geothermal Association IGA:

The IGA is proud to work with all renewable energy associations to continuously provide a unified voice to a cleaner energy future. The Geothermal sector is proven to be a partner of choice for many locations in the world serving baseload power and clean heat to customers. We are particularly interested in the increased attention system integration gets, which underpins the importance of all renewables coming together at events such as the webinar organised by the WWEA.

Christian Rakos, President of the World Bioenergy Association:

The IPCC has emphasized the important role of sustainable bioenergy for climate protection. Recent advances in technology allow us to use feedstock from forestry, wood processing and agricultural production in an efficient and clean way. Today, bioenergy already contributes 12 - 13% to global final energy demand. Importantly, contribution from bioenergy is more than 5 times as much as nuclear energy worldwide. Together with other renewable energy technologies such as solar, wind, geothermal and hydropower, bioenergy can increase the contribution in a substantial way to meet the energy demands of all end use sectors and meet the international energy and climate goals.

Stefan Gsanger, Secretary General of the World Wind Energy Association and Co-chair of the Global100RE Platform:

The switch to a renewable energy future requires new political and economic thinking: from centralised structures with few large actors towards decentralised, participatory models with millions of communities and citizens playing an active role, not only as consumers but also as producers of energy. To make this new paradigm the predominant energy paradigm is the true challenge of the energy transformation which we as the world community are facing. If we manage this shift well and on time, billions of people across the globe, in industrialised and developing countries alike, will benefit and will face a bright future.

Scotland Green Recovery Strategy centers on renewable energy, onshore wind, energy efficiency, battery storage, hydrogen, and electric vehicles, alongside public transport and digital infrastructure, local manufacturing, and grid flexibility to decarbonize industry and communities.

Key Points

A plan to cut emissions by scaling renewables, efficiency, storage, and infrastructure for resilient, low-carbon growth.

✅ Prioritize energy efficiency retrofits in homes and workplaces

✅ Invest in battery storage, hydrogen, and EV charging networks

✅ Support local manufacturing and circular economy supply chains

THE “green recovery” joins the growing list of Covid-era political maxims, while green energy investment could drive recovery, suggesting a bright and environmentally sustainable post-pandemic future lies ahead.

The Prime Minister once again alluded to it recently when he expressed his ambition to see the UK become the “world leader in clean wind energy”. In his typically bombastic style, Boris Johnson declared that everything from our kettles to electric vehicles, with offshore wind energy central to that vision, will be powered by “breezes that blow around these islands” by the next decade.

These comments create a misleading impression about how we can achieve a green recovery, particularly as Covid-19 hit renewables and exposed systemic challenges. While wind turbines have a key role to play, they are just one part of a comprehensive solution requiring a far more in-depth focus on how and why we use energy. We must concentrate our efforts and resources on reducing our overall consumption and increasing energy capture.

This includes making significant energy efficiency improvements to the buildings where we live and work and grasping the lessons of lockdown, including proposals for a fossil fuel lockdown to accelerate climate action, to ensure we operate in a more effective and less environmentally-damaging fashion. Do we really want to return to a world where people commute daily half way across the country for work or fly to New York for a two-hour meeting?

Businesses will need to adapt to new ways of operating outwith the traditional nine-to-five working week to reduce congestion and pollution levels. To make this possible requires Government investment in critical areas such as public transport and digital infrastructure, alongside more pylons to strengthen the grid, across all parts of Scotland to decentralise the economy and enable more people to live and work outside the main cities.

A Government-supported green recovery must rest on making it financially viable for businesses to manufacture here to reduce our reliance on imported goods. This includes processing recycleable materials here rather than shipping them abroad. It also means using locally generated energy to support local jobs and industry. We miss a trick if Scotland simply becomes a power generator for the rest of the UK.

MOVING transport from fossil fuels to renewable fuels will require a step-change that also requires support across all levels. The increased use of electric vehicles and hydrogen fuel cells are all encouraging developments, but these will rely on investment in infrastructure throughout the country if we’re to achieve significant benefits to our environment and our economy.

This brings us to the role of onshore wind power; still the cheapest form of renewable energy, and a sector marked by wind growth despite Covid-19 around the world today. Repowering existing sites with newer and more efficient turbines will certainly increase capacity rapidly, but we must also invest into development projects that will further enhance the capacity and efficiency of existing equipment. This includes improving on the current practice of the National Grid paying operators to switch off wind turbines when excess electricity is produced and instead developing new and innovative means to capture this energy. Government-primed investment into battery storage could help ensure we achieve and further reduce our reliance on traditional, non-sustainable sources.

We need a level playing field so that all forms of energy are judged on their lifetime cost in terms of emissions as well as construction and decommissioning costs to ensure fiscal incentives are applied on a fairer basis.

Turning the maxim of a green recovery into reality will require more than extra wind turbines, and the UK's wind lessons underscore the importance of policy and scale. We need a significant investment and commitment from business and government to limit existing emissions and ensure we capture and use energy more efficiently.

Electrified Trucking Grid Integration explores vehicle-to-grid (V2G) strategies where rolling batteries backfeed power during peak demand, optimizing charging infrastructure, time-of-use pricing, and IESO market operations for Ontario shippers like Nature Fresh Farms.

Key Points

An approach using V2G-enabled electric trucks to support the grid, cut peak costs, and add revenue streams.

✅ Models charging sites, timing, and local grid impacts.

✅ Evaluates V2G backfeed economics and IESO pricing.

✅ Uses Nature Fresh Farms data for logistics and energy.

A University of Windsor project will study whether an electrified trucking industry might not only deliver the goods, but help keep the lights on with the timely off-loading of excess electrons from their powerful batteries via vehicle-to-grid approaches now emerging.

The two-year study is being overseen by Environmental Energy Institute director Rupp Carriveau and associate professor Hanna Moah of the Cross-Border Institute in conjunction with the Leamington-based greenhouse grower Nature Fresh Farms.

“The study will look at what happens if we electrified the transport truck fleet in Ontario to different degrees, considering the power demand for truck fleets that would result,” Carriveau said.

“Where trucks would be charging and how that will affect the electricity grid grid coordination in those locations at specific times. We’ll be able to identify peak times on the demand side.

“On the other side, we have to recognize these are rolling batteries. They may be able to backfeed the grid, sell electricity back to prop the grid up in locations it wasn’t able to in the past.”

The national research organization Mathematics of International Technology and Complex Systems (Mitacs) is funding the $160,000 study, and the Independent Electricity Systems Operator, a Crown corporation responsible for operating Ontario’s electricity market, amid an electricity supply crunch that is boosting storage efforts, is also offering support for the project.

Because of the varying electricity prices in the province based on usage, peak demand and even time of year, Carriveau said there could be times where draining off excess truck battery power will be cheaper than the grid, and vehicle-to-building charging models show how those savings can be realized.

“It could offer the truck owner another revenue stream from his asset, and businesses a cheaper electricity alternative in certain circumstances,” he said.

The local greenhouse industry was a natural fit for the study, said Carriveau, based on the amount of work the university does with the sector along with the fact it is both a large consumer and producer of electricity.

The study will be based on assumptions for electric truck capacity and performance because the low number of such vehicles currently on the road, though large electric bus fleets offer operational insights.

How will an electrified trucking industry affect Ontario’s electricity grid? University of Windsor engineering professor Rupp Carriveau is part of a new study on trucks being used to help deliver electricity as well as their products around Ontario. He is shown on campus on Tuesday, July 6, 2021.

Nature Fresh Farms will supply all its data on power use, logistics, utility costs and shipping schedules to determine if switching to an electrified fleet makes sense for the company.

“As an innovative company, we are always thinking, ‘What is next?’, whether its developments in product varieties, technology or sustainability,” said company CEO Peter Quiring. “Green transportation is the next big focus.

“We were given the opportunity to work closely on this project and offer our operations as a case study to see how we can find feasible alternatives, not only for Nature Fresh Farms or even for companies in agriculture, but for every industry that relies on the transportation of their goods.”

Currently, Nature Fresh Farms doesn’t have any electrified trucks. Carriveau said the second phase of the study might actually involve an electric truck in a pilot project.
