Carbon-based Energy Storage in the Horizon Europe CEEGS Project for the UN Sustainable Development Goals

New approaches to achieving net-zero emissions are necessary in order to successfully battle climate change. The CEEGS technology aims to contribute by integrating carbon capture and storage with electricity-generating technologies. The idea is to combine a renewable energy storage system which functions based on the cyclic injection of CO2 and discharge, with a CO2 storage system implemented in existing subsurface geological formations, along with heat extraction as a component of the cycle. The geological storage also includes sequestration, since a part of the injected CO2 would remain in the underground. The implementation of the CEEGS technology would significantly advance progress towards the UN Sustainable Development Goals, especially Affordable and Clean Energy (7), Industry, Innovation and Infrastructure (9), Sustainable Cities and Communities (11), and Climate Action (13).
