Liquid hydrogen (LH₂) is used for energy supply for various stationary and mobile applications. Current political and economic developments show the need of storable, decentralized produced, green energy to ensure supply of fuel, heat and power for an adequate price [1].
Hydrogen can be part of the solution for those global problems. Especially LH₂ is promising as fuel for mobile applications [2]. It is advantageous because of the high gravimetric energy density, and therefore is used for space applications since decades. Currently, there are many activities, to transfer the LH₂ technology to other applications, e.g. aerospace and trucks.
DLR works on that research topic within various projects together with stakeholders from research institutes, industry. And even SMEs and startups are interested to get their products ready for the operation with hydrogen.
The use of LH₂ is challenging for different reasons, e.g. green and cheap production, storage, transport, and the handling of a cryogenic media. In this paper a LH₂ system will be presented, by an example of a LH₂ refuelling station for an airplane, which will be erected an operated at DLR site in Oberpfaffenhofen (Germany).
