POWER
Summary
Driven by ripe market conditions, technology startups are injecting investment and innovation into geothermal power to unlock novel applications that could substantially scale up the niche renewable power subsector.
While this year’s CERAWeek by S&P Global—an annual energy conference hosted in Houston, Texas—once again heavily focused on energy innovation solutions that span the entire energy ecosystem, U.S. Energy Secretary Jennifer Granholm in a standout moment enthusiastically extolled one: geothermal energy.
Many operational geothermal power plants today are dry-steam plants or flash plants, harnessing temperatures higher than 180C, medium-temperature fields utilizing binary cycle technology are increasingly used for power generation or combined heat and power.
Canadian firm Eavor Technologies, meanwhile, is demonstrating a 2019-built full-scale prototype of its innovative Eavor-Loop technology in Alberta, Canada. The Derek Riddell Eavor-Lite Demonstration Facility connects two vertical wells with many horizontal multilateral wellbores creating a closed-sealed radiator-like system. Eavor, notably, is also building its first 8.2-MWe commercial implementation of an Eavor-Loop in Bavaria south of Munich near Geretsried, Germany.
