Methane Photosynthesis

One thing that might help is that hydrogen diffuses a lot better than oxygen does.

One thing I don't know about is any hydrogen carrier system comparable to haemoglobin/haemocyanin (Earthly organisms use both).

On top of all that, if the energy requirement is lower then perhaps it works with lower-energy photons, so a hydrogen cycle would be favoured on a planet of a cool star?

In any case, we may actually be able to check. Titan has significant levels of hydrogen and methane. Smile

Maybe for a carrier system they use hydrides?

I think this type of photosynthesis uses liquid water instead of the water-ice found on Titan and other similar worlds.
Ever make mistakes in life? Let's make them birds. Yeah, they're birds now.
