Daimler Truck and Linde Engineering have jointly developed refuelling technology for subcooled liquid hydrogen (sLH2).
Unlike regular liquid hydrogen refuelling technology, the new process uses a sLH2 pump to slightly increase the pressure of the fuel, with refuelling time expected to take around 10-15 minutes for a 40-tonne heavy-duty truck with a capacity of 80kg.
In comparison with gaseous hydrogen, this approach also provides a higher storage density, greater range, lower costs, and increased energy efficiency. The technology is expected to lower the required investment for a hydrogen refuelling station “by a factor of two to three”, with operational costs being “five to six times lower.”
