Commercial geothermal technologies are growing with the market based on their applications in low- and high-temperature systems, while progressive technologies are pushing the limits of accessible thermal resources.
Of the approximately 313 MW of new geothermal capacity that came online last year, most of it was from small binary/organic rankine cycle (ORC) projects, but the dominance of new binary/ORC installations in 2015 is not indicative of how the geothermal market will grow in the future, according to a report from the Geothermal Energy Association (GEA).
Flash technologies account for about 58 percent of global geothermal production, dry steam about 25 percent, and binary/ORC 16 percent, the report said.
