Technology Roadmap – Geothermal Heat and Power

The Technology Roadmap for Geothermal Heat and Power offers a strategic plan to maximise deployment of these energy resources by 2050. It projects that 1,400 TWh of electricity per year could come from geothermal power by 2050, up from 67 TWh at present. Additionally, geothermal heat (not including ground-source heat pump technology) could contribute 5.8 EJ (1,600 TWh) annually by 2050. In order to reach these targets, policy makers, local authorities and utilities need to be more aware of the variety of geothermal resources available and of their possible applications. This roadmap describes the technological, economic and non-economic barriers facing geothermal deployment, and the steps stakeholders must take to overcome them.
