February 8 (SeeNews) - Five companies from Germany and Italy have been nominated for the European Geothermal Innovation Award this year, with the winner to be announced on February 25.
The list of companies includes Exergy SpA and its two-pressure-level cycle on a single-disk turbine demonstrated in Denizli Tosunlar geothermal plant. The other Italian company in the contest is Turboden Srl, which has developed a new ORC technology to ramp down output on demand, and new smart grid technology.
Three German firms will also compete. Fangmann Energy Services GmbH & Co KG has been nominated for novel stimulation with acids, and related accessory developments such as spacer, cement, fiberglass casing. GeoKOAX GmbH is also in the list thanks to its geoKOAX heat exchanger, a larger diameter borehole heat exchanger (BHE) with high fluid volume. Jaske & Wolf Verfahrenstechnik GmbH’s nomination is based on the use of water from drawdown-wells in deep open-pit mining for a small district heating system in Bergheim, Germany.
Nominations are assessed in terms of innovation, reliability, reduction of emissions, and gains in energy output.
"This year, the quality of nominations was again high, and virtually no entry was below the threshold to be considered as endorsed nomination," said Burkhard Sanner, president of the European Geothermal Energy Council (EGEC). "I was somewhat surprised to see that the five companies making it on the list are from two countries only, Germany and Italy."
