Hydrogen Jet Engine

• Biobutanol might be an option. Or a heavier version closer to kerosene, produced via some genetically engineered yeasts. Cyberpunk 2020 suggested that, though they called it something else (CHOOH2 to replace gasoline, CHOOH4 to replace diesel and jet fuel, CHOOH6 to replace lube oil. Refers to how many CHOOH groups are hanging off the core molecule). Should require no work to the engines, but there may be some tuning advantages since there's some extra oxygen in the fuel.

That's what the book says. That's also not the exact chemical formula, just the brand name.

Hydrogen for jets

Making jet engines fit for the hydrogen age

Europe is preparing for climate-neutral flight powered by sustainably produced hydrogen. Last year, the EU launched a project to support industry and universities in the development of a hydrogen-powered medium-haul aircraft. Among other things, jet engines will have to be adapted to run on the...

Magnetocaloric cooling method produces liquid hydrogen using environmentally friendly technology

If we want to use hydrogen as fuel for cars or airplanes, or for chemical storage of excess renewable energy, it would be most efficient if it were liquid. However, this would require cooling it down to minus 253°C or 20°K, which is very energy-consuming when using a conventional cooling technology.
