ECA and E4tech (an ERM Group company) completed a study on the potential for using hydrogen in the Energy Community Contracting Parties (CPs), commissioned by the Energy Community Secretariat (ECS). The study comprises four parts (links from the ECS website): an international review of the state of play of the global hydrogen sector; an economic analysis of the projected economic attractiveness of hydrogen across end-use applications; a CP review with a stock take of hydrogen developments in the Energy Community and an evaluation of the readiness and underlying conditions in each individual CP; and a synthesis report providing a summary of the main findings and how these inform a set of policy recommendations and pilot project concepts within the Energy Community.
