Hydrogen economy

electrochemical cell that converts chemical energy into electricity by oxidizing a fuel

a proposed system of delivering energy using hydrogen

vehicle that uses hydrogen fuel for motive power

type of power station

hydrogen generated by renewable energy or from low-carbon power

thumb|Microbial hydrogen production. Biohydrogen is H2 that is produced biologically. Interest is high in this technology because H2 is a clean fuel and can be readily produced from certain kinds of biomass, including biological waste. Furthermore some photosynthetic microorganisms are capable of producing H2 directly from water splitting using light as energy source.
