Abstract
Bioenergy comes from biomass that is used to produce power, heat or vehicle fuels (‘biofuel’). The main constraint on the quantity of bioenergy that is available is land, given the need also for land to produce food for a growing population and to leave space for forests and wildlife. This chapter explores the availability of biomass under different assumptions and the various controversies around its production. Zero-carbon energy scenarios also usually see a role for hydrogen. The most common processes for hydrogen production are steam reformation of fossil methane gas, or electrolysis of water with renewable electricity. Hydrogen has a wide range of uses – for heat, power and transport – for which it can be burned, used in fuel cells for power generation, converted into synthetic fuels (‘synfuels’ or ‘e-fuels’) or used in the direct reduction of iron for steel-making. There is now considerable investment going into the manufacture of electrolysers to produce ‘green’ hydrogen, so it may be that after a long gestation period, this energy source will become more widely used over the next 20 years.
