Hello,

I've heard some stuff about a bio digester that does not produce methane but hydrogen. Does someone know if this could be done at home? That would be very interesting if it could be done.

Matis, you might be considering a biomass gasifier. These can generate quite a bit of H2. The primary fuel gas is usually CO, but H2 is often a close second.
