Fuels for space
- Notes from speaking to David Thompson
- Oxygen - O2 as byproduct of photosynthesis
- Hydrogen - via the biohydrogen route
- nitrogenase, the enzyme that fixes N2 to NH3, as a normal part of its function it produces H2 albeit at a much slower rate than NH3, its a side reaction. but if you force the reaction in an atmosphere with zero nitrogen, then you get H2 production exclusively.
(Hydrogen-2, H-2, 2H (a.k.a. Deuterium), an isotope of Hydrogen (1 proton, 1 neutron, 1 electron))
- Deep sea bacteria that make hydrazine as a free metabolic intermediate. (Hydrazine is used as a bipropellant in combination with O2 I (DT) believe,and some of its derivatives are used in combination with other liquid rocket fuels...)
