EU GREEN WEEK PARTNER EVENT: Concentrated solar power (CSP) and sCO2 – perfect match towards a zero-pollution future

June 4, 2021


Event description:

Concentrated solar power (CSP) and supercritical carbon dioxide (sCO2) will be the perfect match for decarbonising the energy system towards a zero-pollution future.

This event is hosted as partner event in the framework of the EU Green Week 2021: https://www.eugreenweek.eu/partner-events/concentrated-solar-power-csp-and-sco2-perfect-match-towards-zero-pollution-future

CSP, a 100% green solar energy with zero emission

CSP technologies use mirrors to concentrate the sun’s heat onto a receiver to generate electricity by converting solar thermal energy from sunlight to drive traditional steam turbines or engines. CSP plant’s built-in thermal energy storage system is able to continue generating electricity at night and has the ability to replace conventional power plants with 24/7 clean electricity. CSP electricity generation produces no carbon dioxide nor other heat-trapping gases that contribute to climate change, nor other harmful emissions or wastes associated with coal power.

sCO2, an efficient way to reduce emission

What is sCO2? sCO2 is a fluid state of carbon dioxide where it is heated and held at or above its critical temperature and pressure. This phase of CO2 is commonly used as a solvent in chemical extraction processes due to its high solubility, low toxicity and minimal net effect on the environment. In recent years, supercritical CO2 cycles can be configured to accommodate the temperature and pressure characteristics of various heat sources, providing superior efficiency in converting heat to electrical power. This process reduces atmospheric emissions to zero.

Therefore, sCO2 could be the perfect match for CSP in new power plant designs to increase efficiency while cutting costs, and at the same time achieving the goals of decarbonation and combating the climate change.


SOLARSCO2OL is a Horizon2020 funded project aiming at unlocking the potential of integrating sCO2 power block in all kinds of CSP plants. A short webinar was hosted by SOLARSCO2OL partners to present the project concept and how sCO2 can be used in CSP power plant to archive the decarbonisation of energy system.


Key consortium partners from both sCO2 turbomachinery and CSP sectors presented their R&D activities and how they consider SOLARSCO2OL Strategic to achieve their objective and CSP vision.
