It’s been hailed as fuel of the future. Hydrogen is clean, flexible and energy efficient. But in practice there are huge hurdles to overcome before widespread adoption can be achieved.
This video covers each of the following topics:
00:00 How hydrogen fuel is generated.
02:04 How hydrogen fuel could be used.
02:46 Why hydrogen fuel hasn’t taken off in the past.
03:40 Is hydrogen fuel safe?
04:31 Hydrogen’s advantage over batteries.
05:00 How sustainable is hydrogen fuel?
06:13 Why the hype about hydrogen may be different this time.

Is green hydrogen the answer to the climate crisis?
>>> DW (German) Documentary, Nov 2, 2021
Green hydrogen produces zero emissions and many believe it holds the key to limiting global warming. So is it the big hope for the future or a multi-billion euro mistake?
Many believe green hydrogen could provide a miracle solution for countries around the world seeking to decarbonize their economies. But the technology is still in its infancy. Generating sufficient quantities of green hydrogen would require a lot more renewable energy than is currently available.
Right now, almost all hydrogen is produced using natural gas in a process that generates large amounts of carbon dioxide. Green hydrogen, by contrast, is climate neutral. It’s derived using renewable energy. The principle itself is not new but has, at yet, only found limited usage.
Engineers at the German Aerospace Center are now working with the world’s largest artificial sun to try to produce hydrogen without any electricity at all, using only light. If they can succeed, it would allow large-scale production of this valuable gas in countries that receive a lot of sunshine.
Hydrogen is already being used as a fuel for buses, trains and cars, with hydrogen-powered planes due to follow shortly. Hydrogen is even the fuel of choice for space rockets, and German submarines glide along almost in silence thanks to hydrogen fuel cells.
Manufacturers of airplanes, trucks, and even steel are investing millions in the technology, hoping that hydrogen will be the go-to fuel of a climate-neutral future. But critics warn of major challenges ahead, saying billions stand to be wasted.

“World’s largest” electrolyser arrives in Norway to scale up green hydrogen projects
Norwegian HydrogenPro, a provider of solutions for producing, storing, and distributing hydrogen from renewable energy sources, has received what is said to be the world’s largest electrolyser at its test facility at Herøya.
The electrolyser, which was manufactured at HydrogenPro’s factory in Tianjin, China, arrived at the Herøya test facility on 10 September, marking a milestone in the company’s history.
“This project is a critical milestone for large, green hydrogen projects. It requires substantial planning, rigging and the right equipment. This project is important to facilitate larger, green hydrogen projects, reducing carbon footprints and costs”, said HydrogenPro’s CPO Karoline Aafos.
According to Erik Christian Bolstad, the company’s CCO, the plant results will help optimise HydrogenPro’s deliver to one of the world’s largest factories for green hydrogen.
The electrolyser is expected to have an output of 1100 Nm3/h hydrogen at normal current density. This equals 100 kg of pure hydrogen per hour, which will set a new standard for the industry, the company claims.
The test aims to verify that the electrolyser produces the expected amount of gas per unit of time. During the test, HydrogenPro intends to use fluctuating electricity input from renewable energy sources and test several other parameters.
The electrolyser will be assembled and installed in the upcoming weeks, with the validation process initiated when possible.

Imperial awards hydrogen contract to Air Products
DCN-JOC News Services September 14, 2022
EDMONTON – Imperial has announced a long-term contract with Air Products to supply low-carbon hydrogen for the company’s proposed renewable diesel complex at its Strathcona refinery near Edmonton.
Air Products will provide pipeline supply from its hydrogen plant currently under construction in Edmonton.
“Our agreement with Air Products is an important milestone as we progress plans to build the largest renewable diesel manufacturing facility in Canada. This project highlights Imperial’s commitment to investing in a lower carbon future. We continue to progress discussions with our business partners and governments as we work toward a final investment decision in the months ahead,” Imperial downstream vice-president Jon Wetmore said in a statement.
Imperial will use Air Product’s low-carbon hydrogen to produce renewable diesel at its Strathcona facility that “substantially reduces greenhouse gas emissions relative to conventional production. The hydrogen and biofeedstock will be combined with a proprietary catalyst to produce premium low-carbon diesel fuel,” a release said.
“There is significant demand for low-carbon hydrogen, and as a first-mover, Air Products is ready to meet that demand from our Alberta Blue Hydrogen Hub. Canada is rapidly implementing an energy transition that emphasizes the use of low-carbon hydrogen, and Air Products is demonstrating that world-scale hydrogen facilities can be net-zero for carbon emissions.
We continue to set the stage for a competitive, low-carbon-intensity hydrogen network, which includes increasing liquid hydrogen production capacity at our site to 35 metric tonnes per day, to provide clean hydrogen for the growing industrial and mobility markets across Canada,” said Air Products COO Dr. Samir Serhan.
Air Products is increasing overall investment in the Edmonton facility to $1.6 billion to support the Imperial contract, the release stated, with the investment used to facilitate integration with Imperial’s proposed project and supply it with approximately 50 per cent of the low-carbon hydrogen output from its 165 million standard cubic feet per day hydrogen production complex.
Imperial’s renewable diesel complex is expected to produce more than one billion litres of renewable diesel from locally sourced feedstock and the project, first announced in August 2021, is “anticipated to realize about three million tonnes per year in emissions reductions in the Canadian transportation sector,” the release stated.
