The U.S. Department of Energy (DOE) Geothermal Technologies Office’s (GTO) GeoVision Report (“GVR”), released earlier in 2019, has all sorts of tidbits that may be appetizing to international geothermalists. For the sake of interested renewable energy students or professionals that might balk at reading the entire 218 page, seemingly U.S.-focused document, I pulled some key points out for contemplation that have wider geographic applicability. Refer to this LinkedIn post here for more details. Naturally it would be best to read the whole thing, but the post is a start.

Something refreshing is that ThinkGeo reposted the article and “riffed” on it with more interpretation and a new figure. You can find that link here. They included a Sankey diagram showing the proportions of total potential geothermal energy that flows to various uses. I appreciated their not simply reposting the article as is, but instead taking some time to reflect on what other ideas it generated, and coming up with yet another way to visualize data.

One of the most important tables in the GeoVision report is Table 3-3, which sets out basic design criteria for the various scenarios in the report. If a student is looking for reasonable and current starting data reference for a mini-study, regarding performance and economics, they could do worse than looking at the Table 3-3 assumptions. Would include it here, but then people really should delve into the full report.

If anyone happens to be at the Geothermal Resources Council Annual meeting this year (15-18 September in Palm Springs) and wants to chat about GeoVision or other topics, stop by the POWER Engineers booth and ask for me. It looks like we are right around the corner from the Department of Energy and the primary authors of the report. I’ll be around and always enjoy talking power plants and careers.
