A project funded by the EU Research and Innovation Programme Horizon 2020, known as CO2OLHEAT, officially began on the 1st of June 2021.

With an overall budget of around €18.8m, the aim of the project is to utilise the energy potential of unused industrial waste heat and transform it into power.

The project is set to run for four years, between June 2021 and May 2025.

A consortium of 21 partners has been formed that will collaborate on developing innovative, cutting edge supercritical CO2 (sCO2) technologies, such as an economically viable and replicable 2Mw sCO2 power block.

The CEMEX cement plant in Prachovice, Czech Republic, will demonstrate the sCO2 power block technology.

The project will have replication potential within multiple different industries and locations across Europe. This includes the glass industry (Turkey), aluminium (Greece), steel (Spain), waste incineration (Belgium), gas power generation (France), and solar power generation, also in Spain.

CO2OLHEAT’s waste-heat-to-power (WH2P) application is based upon a recuperated closed-loop Brayton cycle - a thermodynamic cycle that describes how gas turbines operate - with sCO2 as a working fluid.

The sCO2 power block is able to better accommodate load changes and through its compact size, high efficiency and ability to work with significant temperatures, can offset the disadvantages of traditional WH2P applications.

With the unused heat in heavy industries (chemical, iron & steel and cement manufacturing) accounting for more than half of all the EU industrial waste-heat (WH) potential, the application of circular economy and heat management technology will help contribute towards CO2OLHEAT saving primary energy consumption and further reducing CO2 emissions.

Combining 21 partners from 11 different European countries, the CO2OLHEAT consortium includes partners from all previously EU funded projects on sCO2 cycles.
