Europe is saying goodbye to natural gas for good with a superturbine that will produce the substitute energy. Although demand for natural gas has fallen in recent years, the continent remains dependent on it as an alternative to coal, a fossil fuel it wants to replace with pure hydrogen. However, to achieve this, a combustion system must first emerge that can work efficiently with any concentration of H mix, including 100%.
Different nations aim to achieve decarbonization through a gradual energy transition. In this search for new alternatives to fossil fuels, hydrogen has many possibilities. Its production for energy purposes is a field of worldwide exploration. Moreover, investment to produce H with low carbon emissions is growing.
Already in 2022, Spain was leading 20% of the world’s new H projects. “Just for context, China’s current consumption is 20 million tons of hydrogen. This is the same amount that Europe needs to produce in 2030 to replace Russian gas,” says Africa Castro, head of business development at the firm H2B2, in the H2 podcast.
Europe has a superturbine to accelerate hydrogen deployment
This is no small thing. Talk of a turbine capable of running on 100% hydrogen is a big word, or at least it was until now. The FLEX4H2 initiative is being funded by the European Union and the Swiss government and has shown that this possibility exists in just one year of research.
The Italian company Ansaldo Energia has developed the GT36 turbine, which has been commissioned in Germany with 100% H concentration. It is an H-class turbine, a sophisticated type of gas turbine designed to achieve extremely high efficiencies and operating temperatures.

Too bad it takes more energy to produce and have enough hydrogen to be used as a fuel, than the energy produced once the explosive chemical reaction in a turbine or cylinder takes place.
The hydrogen mines are all going to be up and running within the next decade. Or so. Maybe.
Obtaining useful energy from a perpetual motion machine is a much easier engineering problem to solve.
BURN the hydrogen? Isn’t it simpler to run it through a fuel cell, and generate the electricity directly? No heat pollution, and the solution is much more elegant.
“Could it be that pure hydrogen as opposed to a mixture causes too much wear through metal embrittlement!”
I imagine so. The article gives next to no specifics.
I’m old enough to remember when “H” was street slang for Heroin.
Now it’s going to mean just another expensive addiction.
Good question, all the methods I have seen to produce H require the same energy to make H you get back when you burn it.
Plus hydrogen gas is hard to store or liquefy.
This person needs to place the blotter acid on the table and just back away. Basic energy knowledge passed this person by.
Where are they going to get the hydrogen? OH yeah, right, drill for it. Never mind that after drilling wells all over the world for 40 years I never once encountered any hydrogen. NEVER. Good luck with that.
These people run in circles. It is no different than the clowns that connect an alternator to a generator as an infinite source of energy. Where is the H2 coming from? These articles are always incomplete. Ass, cash, or energy, nothing comes for free.
“Hydrogen gas forms explosive mixtures with air in concentrations from 4-74%” (Wikipedia), making leaks especially dangerous.
The whole problem with this is creating some sort container that H cannot leak through. Creating that container also consumes energy from extraction to manufacture.
It’s really quite simple. Just get an Obama appointed judge to repeal the first and second laws of thermodynamics.
Hydrogen leaks
bkmk
Why stop there? Gravity seems to be an impediment. Ban it.
Yes. Hydrogen embrittlement of metals is a serious problem. Metals weaken significantly when exposed to H2 for long periods. So simple high pressure steel tanks are out of the question.
We have ENORMOUS supplies of hydrogen, most of it conveniently packaged in the H2O molecule. Extracting it from said molecule ... now that's the trick, isn't it?
The Interstate power project (IPP) in Utah is already building a H2 powered power plant. Uses Japanese turbines.
See https://www.ipautah.com/ipp-renewed/
2 x 400 MW solar farms run a set of massive crackers, the H2 produced goes into a salt dome for storage, then use.
All of this expensive power will go to Calif - cause Green and all. LOL for their cost.
Yes.
From DC to gamma rays, it's all "light".
And now you know.
BUT, the amount of hydrogen needed to cool a generator is a minuscule fraction of what would be needed to fuel the turbine. For some good insights on power plants safely handle hydrogen and the attendant risks, see "Cooling generators with hydrogen: Safe handling practices."

Imagine scaling those hydrogen handling practices to utility scale generation!
A couple of interesting items from the article...
"Because hydrogen molecules are tiny, it’s virtually impossible to avoid leakage. Because of the small molecule size, there is a constant flow of hydrogen into and from the seal oil system. This is unavoidable, so it is important to have a means of continuous liberation, or “detraining” the hydrogen from the oil. The generator shaft seals by design are not 100% “leak proof,” so gas must be added regularly to maintain the proper pressure and purity. Minor leakage from the shaft seals usually does not present any hazards because most turbine and generator areas are well-ventilated, so the gas escaping will never reach dangerous concentrations. On the other hand, generators which are installed partially below the turbine deck can actually have hydrogen accumulations below a concrete turbine deck. These areas require frequent (or continuous) monitoring for unsafe concentrations."Imagine not being able to see the hydrogen fire or feel any radiant heat from it. Imagine walking into a 2,254 degree hydrogen fire you cannot see or feel."When hydrogen is burning (oxidizing), it does not produce a visible flame. Therefore, it produces very little (if any) radiant heat. This is very dangerous because when radiant heat is created, personnel can feel the heat from far away. With hydrogen, a person could simply walk right into the fire, being subject to severe burns and hot gas inhalation."
It’s all electromagnetic RADIATION! It’s everywhere! The sun bathes you in it. Light bulbs irradiate you constantly! Cell phones. Radar from airplanes and airports! The horror! RADIATION! Only by ending technological civilization can you be spared a horrible RADIATION death!
Idiots.
