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.
It's more like the Jupiter 1 "fuel consumption" for 30mw output can be way overestimated.
More technical description is combustion is 50% as efficient as a fuel cell. It is very significant difference.
