The Clean Hydrogen Partnership (formerly referred to as the “Fuel Cell and Hydrogen Joint Undertaking”) has supported and co-financed the PACE project and, in the past, the ene.field project for the dissemination and development of fuel cell micro-cogeneration. In particular, the PACE project wanted to demonstrate that this technology is sustainable at a technological and environmental level, as well as at an economic level, and the Clean Hydrogen Partnership has contributed to research and to accelerating its diffusion on a large scale.
