Geothermal Power Primer — Turning Underground Heat Into Electricity with Flash and Binary Systems
Geothermal power is a stable energy source sitting right under the feet of volcanic Japan, yet even though the country ranks third in the world for resource potential, installed capacity captures only a fraction of it. This article diagrams the difference between flash and binary systems, the risks of resource assessment and drilling, the regulatory tangle around hot springs and national parks, and next-generation technologies such as EGS and supercritical geothermal.
