TWI wins €17 million GeoSmart project

Mon, 25 February, 2019

TWI will coordinate part of a new €17 million collaborative project to develop technologies to allow geothermal plants to cost-effectively respond to network heat and power demands.

The project, which is funded through the EU’s H2020 fund, has 19 partners across Europe, with TWI overseeing a €3.8 million budget to combine thermal energy storage with flexible organic rankine cycle (ORC) solutions to provide a highly flexible operational capability for geothermal installations.

The project aims to find methods to store heat energy when demand is low so that it can be released later at times when demand is high. This will not impact critical infrastructures under variable energy generation as the approach will not influence the flow condition at the wellhead.

The project also plans to create a hybrid cooling system for the ORC plant that will prevent efficiency degradation due to seasonal changes and thereby improve efficiency.

Such efficiency improvements will be increased by a scaling reduction system of specially designed retention tanks, heat exchangers and recombining extracted gases. This will enable larger power plant heat extraction while the scaling reduction system alone has the potential to double the power production from many medium enthalpy geothermal plants.

Overall, GeoSmart technologies aim to drastically reduce geothermal energy costs, making it cost competitive with fossil fuel-based counterparts.

With the collaborative work set to begin in May 2019, we will have more information on the project as it progresses.
