Hydrogen storage is well known to be the major bottleneck for the use of H2 as energy carrier. Actually there are few storage systems available for nice markets. The EDen project is addressing a technology able to store energy in form of hydrogen in a solid state material. EDEN is proposing a high density, fully integrated material – tank – engineered system. This work presents a novel approach for the thermal management of a hydrogen tank based on metal hydrides, working at temperatures around 350°C and thus compatible with SOFC.
