BERLIN, Feb 1 (Reuters) - Germany's EnBW EBKG.DE said on Sunday it had signed a memorandum of understanding with Saudi Arabia's Acwa 2082.SE to develop a pathway to import and treat ammonia for use in German hydrogen energy projects.

Germany is seeking to build up its hydrogen capacity to help it meet clean energy targets, and some 50%-70% of its needs will have to be imported, authorities have said.

EnBW said in a statement that the MoU, signed during a visit to Saudi Arabia by a delegation led by German Economy Minister Katherina Reiche, included VNG VNG.UL, one of Germany's biggest LNG importers, in which it has a majority stake, and the port of Rostock in northeastern Germany.

"The signing of this memorandum of understanding is an important milestone for all partners involved," EnBW CEO Georg Stamatelopoulos said, adding: "We are driving forward the establishment of a reliable import corridor for green ammonia from Saudi Arabia to Germany".

VNG is to develop a cracker facility in Rostock to extract hydrogen from the ammonia to be fed into the German hydrogen core network, the statement said.

The system is due to go into operation from 2030.
