Abstract

Geothermal energy is utilised by drilling a borehole to a depth of 10,000m and circulating water through the borehole in a closed circuit. The steam, developed by the geothermal gradient, drives a steam turbine on the surface and its condensate is passed down the hole. The electric generator, driven by the turbine produces electrical current which is used to produce hydrogen from water by electrolysis. The hydrogen can be bottled and used to drive cars fitted with gas engines or to power aircraft and ships.
