NORWEGIAN HYDRO ENERGY IN GERMANY (NHEG)

Transfer of renewable energy from remote areas to energy-intensive industrial regions might be of prospective importance. The case study NHEG considers a system where Norwegian hydro-energy is exported to Germany as hydrogen or electricity. The goal was to evaluate the technical and economical feasibility of a demonstration project, paving the way for larger commercial projects in the future. Primarily, hydrogen is considered as the energy carrier. Liquid hydrogen is produced in North Norway, shipped to German ports and distributed to specific cities. Three alternatives are studied. The reference case is based on 100 MW hydro-power, the two others on 20 MW. In the former, a ship with fixed cryogenic tanks is applied for the LH-2 maritime transport and cryogenic 40 ft containers with ISO standard dimensions are applied for distribution to the users. In the latter two cases, the containers are supposed to be used for both transport and distribution. In all cases,evaporated GH-2 is assumed to be returned to the production plant for reliquefaction.
