ENEA, the Italian National Agency for New Technologies, Energy and Sustainable Economic Development, will lead an interdisciplinary consortium of nine European partners to develop an innovative prototype for high-temperature electrolysis, using renewable solar heat and power to produce green hydrogen in a continuous way. By working in close connection with leading European industrial companies, this challenging and innovative project called 'PROMETEO', will contribute to move a step forward in decarbonising the energy, chemical and nitrogen fertiliser sectors, in line with the EU decarbonisation targets by 2030.
