ElectraTherm ships 2nd geothermal Power+ Generator to Japan

ElectraTherm Inc, a US developer and manufacturer of distributed, waste heat to power generation using Organic Rankine Cycle (ORC) technology has announced that it has shipped a Power+ Generator to a geothermal site in Japan.

According to a statement, this marks the second Power+ Generator in Japan utilizing geothermal heat to generate fuel-free, emission-free electricity. The Power+ runs off low-temperature geothermal steam, and the power generated is sold to the local utility at an attractive feed-in-tariff rate for renewables.

There is a great potential for these micro-geothermal sites across Japan and we look forward to each unit we deliver progressing the market further. Japan offers an attractive feed-in-tariff rate for geothermal at JYP40 per kW (≈US$0.33), which makes these baseload renewable energy projects attractive, said John Fox, Managing Director for ElectraTherm.

ElectraTherm utilizes Organic Rankine Cycle (ORC) and proprietary technologies to generate 65 kWe gross of electricity at this site. The Power+ Generator captures low-temperature heat at 116˚C and 45.4 m3 per hour flow rate. Unlike other renewable sources, geothermal heat is baseload, providing a continuous hot water flow with power generation capabilities 24/7. Hot geothermal water is the “fuel” used.

The Power+ Generator utilizes waste heat on applications such as internal combustion engines, biomass boilers, flare gas at oil and gas wells, wastewater treatment plants and landfills, geothermal/co-produced fluids used to create a high-pressure vapour that expands through ElectraTherm’s twin screw power block, spinning an electric generator to produce clean electricity.
