Permanent magnet-free linear drives with high force density for H2 re-compression systems

Green hydrogen is considered a beacon of hope in the field of decarbonization in industry. To transport hydrogen from the production plant to the end customer, the gas must be compressed and filled into cylinders or directly into H2 trailers. Typical pressures are in the range of 500 bar and are achieved using piston compressors. Inevitably, leakage occurs, resulting in the loss of valuable green hydrogen. The aim of this project is to identify solution strategies for hermetic recompression of the leaked gas that make sense both technically and economically. Thus, a new approach for an electromagnetically safe drive is being designed, analyzed, and evaluated on the test bench.
