SEDIMENTARY BASINS OF #ALGERIA: THEIR ROLE IN #EUROPE ’S ENERGY SECURITY AND EMERGING GREEN #HYDROGEN FUTURE
Canadian scientists at the University of Alberta have revolutionized #hydrogen production by developing a cutting-edge method to split water using sunlight and urea, potentially transforming the future of clean energy.
In this #interview from our #Energy and #Climate blog, Axel and I talk to German professor #ChristopherHebling, who, as Director of International Affairs at the Fraunhofer Institute for Solar Energy Systems ISE, has been elected to the board of the Forum for Future Energies e.V.
Ballard Power Systems has announced the signing of a new supply agreement with California-based rail operator Sierra Northern Railway for the supply of 1.5 MW of fuel cell engines, expected to be delivered in 2025. #hydrogen

The test is part of Honda’s vision to support life on the Moon and elsewhere in space using regenerative fuel cell technology that continuously produces hydrogen, oxygen, and electricity.
The common mini-Neptunes typically form with a #hydrogen#atmosphere, resulting in conditions where #hydrogen and the #planet’s molten interior interact for millions to billions of years.
But the temperatures and pressures involved are so extreme that laboratory experiments to study them are nearly impossible.
Water and hydrogen would begin to separate deep within the atmosphere leading to rainfall deep inside the planet’s atmosphere as heavier water sinks.
Coca-Cola is installing what the company claims to be the world’s first hydrogen-powered vending machines at the World Expo 2025, which will open to the public in Osaka, Japan, on April 13th, 2025. Co-developed by Fuji Electric, the machines don’t need access to a power outlet and instead rely on replaceable hydrogen cartridges to fuel a chemical reaction that generates electricity, @theverge reports: https://www.theverge.com/news/633779/coca-cola-fuji-electric-vending-machine-hydrogen-power
"It makes little sense to waste electricity to produce hydrogen — which has conversion losses — rather than directly powering an electric car or heat pump."
Delhi: While taking the tour in a hydrogen based green fuel bus in Delhi, American guests praised the bjp government in India and said that considering the environment in India, hydrogen buses will prove to be cost-effective and beneficial. The central government at the center is taking a good initiative, the environment will ...
The Well to Wheel efficiency of Hydrogen is circa 30%, some 70% of input energy being wasted in the process of converting it to Hydrogen, transporting it, and re-converting it to electricity. (https://sci-hub.st/https://doi.org/10.1051/rees/2016033)
Hydrogen advocates say "so what, at least that 30% will be there as long as you need it, unlike batteries which self-discharge".
So, let's ignore for a second that the smallest molecule in nature is inherently leaky, and focus on the self discharge...

This shows that starting from Renewable electricity (100% of energy input) the process of converting, transporting and re-converting the H2 causes significant losses.
The Round trip efficiency of a Lithium battery with no self discharge is circa 80%, so only some 20% energy is wasted in the process of storing and recovering it.
Self discharge rates for Lithium Ion batteries are circa 5% per month.
So, unless you're planning on storing some energy for > 19 months you're better off using batteries.
The UK Civil Aviation Authority (CAA) is preparing to roll out the second round of its ‘Hydrogen Challenge’, which will feature designs for “cutting-edge aircraft” and flight trials.
