The Fuel Cells and Hydrogen Joint Undertaking is a unique public private partnership supporting research, technological development and demonstration (RTD) activities in fuel cell and hydrogen energy technologies in Europe. Its aim is to accelerate the market introduction of these technologies, realising their potential as an instrument in achieving a carbon-lean energy system.
On 6 May 2014, the Council of the European Union adopted the Regulation establishing the ECSEL Joint Undertaking. This new organisation replaces ARTEMIS JU and ENIAC JU. ECSEL JU has become operational as of 27 June 2014.
