Climate change is a huge threat that matters to each and every one of us. It’s enough to consider that 2020 was one of the hottest years on record and that as many as 22 climate disasters have hit the United States over this period (including fires, earthquakes and tropical storms). The path towards sustainability has already been clearly outlined and is based on three main pillars: an increase in energy efficiency, decarbonization of the energy supply and the use of alternative fuels. The various tools capable of supporting this transition certainly include high-efficiency cogeneration, a fundamental element for the industrial sector where CO2 emissions are concentrated, particularly when it will be powered by renewable fuels such as hydrogen.
