The first enhanced geothermal system (EGS) project started more than 50 years ago. Since then, over 100 EGS projects have been launched around the world, improving the technology and reducing costs. To track progress over time, we built a database of 103 projects using information from more than 400 sources. Our analysis found seven major trends: 1) drilling is getting faster; 2) projects are targeting hotter temperatures; 3) wells are getting deeper; 4) energy production is improving; 5) drilling costs are falling; and 6) new EGS projects have over ten times more capacity than all previous projects combined. These trends show that EGS is gaining momentum and moving toward deeper, hotter, and more affordable energy production. However, there are still challenges to solve, including: 1) how long these systems can produce energy efficiently; 2) how to manage earthquakes induced by geothermal development; 3) how to successfully develop EGS projects in new areas; and 4) how to make data more open and consistent. To support future growth, we are building a public database to track EGS progress. Updating the database over the next decades will help guide research as EGS grows and moves toward higher temperature systems like superhot rock.
