    Jupiter 1 hydrogen gas generator engine

    https://newatlas.com/energy/worlds-largest-pure-hydrogen-electrical-generator/

    at 15kg per kw, this is 300x less efficient than a fuel cell for just electricity output. Distributed fuel cells can use waste heat for domestic hot water needs.

    A better use of combusting H2 for electrical power generation, is changing the input valves on electrical generating NG turbines. That is just 2x less efficient than a fuel cell.

      Interesting but I’m skeptical that they would develop this if they could simply convert a NG turbine and it would only be 2x less efficient.
