Fuel Cells are a promising technology in the context of clean power sustainability and alternative fuels for shipping. Different specific developments on Fuel Cells are available today, with research and pilot projects under evaluation that have revealed strong potential for further scaled up implementation. The EMSA Study on the use of Fuel Cells in Shipping has been the result of this Agency's initiative, under the agreement of the Commission and in support of EU Member States, an important instrument, developed in close partnership with DNV-GL.
