German hydrogen plans

Thank you for the reminder.


New natural gas power generation capacity will be built in Germany, to provide the required backup for intermittent wind and solar power.

The article says the new gas plants will be capable of burning green hydrogen for fuel, but I’ll believe that when I see it. As described earlier in this thread, natural gas, or hydrogen produced from natural gas, is much less expensive than green hydrogen produced from renewables.

Germany’s hydrogen plans have had a setback since a court ruling triggered a budget crises.

Germany was counting on clean hydrogen to replace its natural gas, allowing the country to run a climate-friendly grid by 2035. Last August, the government announced its lavish subsidies to make these ambitions possible. The plan involved building “8.8 GW of dedicated hydrogen power plants, alongside 15 GW of natural gas-powered ones that ought to switch to hydrogen by 2035 at the latest, in total representing about one-third of the German peak power demand of 2023,” reports Euractiv.

This was good news for the Energiewende because the hydrogen plants were meant to cover the gaps in renewable generation, which can go dead for weeks at a time in Germany.

But then a budget crisis hit the government. The crucial $7.6 billion needed to even begin this project evaporated. What does that mean? More coal, says the chief of a leading Germany industrial group, BDI.



Choices must be made.

Have they solved the hydrogen embrittlement problem? Or do they plan to replace or upgrade (coat the inside of?) All gas pipelines?

Is there a magical additive for hydrogen in steel pipelines?

The cost to produce hydrogen fuel via electrolysis is driven primarily by a single variable: the cost of electricity. Because electricity costs have the biggest impact on the financial viability of clean hydrogen, it is imperative that hydrogen electrolyzers consume as little electricity as possible. Researchers at Idaho National Laboratory (INL) have been conducting a variety of tests on Bloom Energy’s solid oxide electrolyzer at the Dynamic Energy Testing and Integration Laboratory.

Running at high temperatures and high availability, the pilot results reveal the Bloom Electrolyzer is producing hydrogen at 37.7 kWh per kilogram of hydrogen. Alternative electrolyzer technologies, such as PEM or Alkaline, consume as much as 52 – 54 kWh per kilogram of hydrogen produced.
