The most efficient method of extracting energy from hydrogen and oxygen is through Fuel Cell Technology, which offers an efficiency range of 35% to 60% for converting chemical energy to electrical energy. Internal Combustion Engines (ICE) using hydrogen can achieve combustion efficiencies of approximately 60%, while steam turbines rank lower in practicality and efficiency. Electrolysis of water, particularly when combined with heat, can reach efficiencies above 70% with the use of catalysts. However, hydrogen production and storage remain significant challenges in the energy landscape.
PREREQUISITESEngineers, researchers, and policymakers interested in alternative energy solutions, specifically those focusing on hydrogen as a clean energy source and its applications in fuel cells and combustion engines.
mheslep said:Hydrogen and natural gas flame temperatures are very similar.
Yes. There's a lot of engineering in the heat management of gas turbine engines. Heat resistant metals or ceramics are used, and the combustion gasses are rapidly expanded which cools them.Lok said:... It melts at about 1500 plus give Celsius.From a historical point of view where natural gas was very abundant. No.
Lok said:Fuel cells do not require pure hidrogen, not that pure hydrogen is that hard to get. Engines are actually more fussy about purity, I mean a constant purity that it is set.

I can't reference a model number, only this at the moment:Topher925 said:Do they actually use ceramics commercially in heat turbines these days? I thought the failure rate of ceramics was still to unpredictable.
