Most installed geothermal capacity today exploits naturally occurring pockets of steam or hot water, close to the Earth's surface, to generate electricity. Because such conditions are rare, the majority of today's geothermal power capacity is located in rift zones or volcanically active parts of the world where such anomalies are more likely to be present. With a handful of demonstration projects targeting unconventional resources, such as coproduction from oil and gas wells and enhanced geothermal systems (EGS), and new projects proliferating in underutilized areas of the world where conventional geothermal capacity remains untapped, the geothermal project development pipeline continues to expand.
All told, Pike Research has identified 567 geothermal power projects in development worldwide, including new concessions recently granted to developers and fields fast-tracked for priority development by national governments. An estimated 15% of projects have reached advanced development stages, representing 5.3 GW of potential capacity slated to come online by 2018.
This Pike Research report includes a database covering geothermal power projects targeting hydrothermal, EGS, and coproduction resources. The database lists projects by geographic region and provides key metrics on development stage, resource temperature characteristics, expected project completion date, and total capacity. The goal of this database is to provide the best up-to-date summary of geothermal power projects available globally.
Key Questions Addressed: • What is the current status of geothermal projects worldwide?
• Which countries and regions are poised for the greatest growth in geothermal capacity worldwide?
• What impact will unconventional resources (EGS and coproduced) have on geothermal capacity worldwide?
