Global electricity demand is growing faster than renewables, driving strong increase in generation from fossil fuels. As a result, carbon emissions from the electricity sector, which fell in both 2019 and 2020, are projected to increase in 2021 and in 2022. In a path towards meeting the international goals on climate change, the energy sector is going through epochal changes that involve in a transversal way the methods of supplying, transporting, storing and using energy. In this context, mitigation actions against CO2 emissions are becoming increasingly fundamental. A recent analysis published by IEA highlighted that one of the key technology areas for putting energy systems on a sustainable trajectory is represented by carbon capture, utilisation and storage (CCUS).
