There are currently various challenges associated to the production of low-cost liquid hydrogen:

• Only few developments working on optimising hydrogen cycles at a high TRL have been proposed;
• Current hydrogen energy consumption for liquefaction is around 10 to 12 kWh/kg equivalent to 35% of the hydrogen energy content on LHV vs power basis;
• Market development and cost strategies need to be developed for viable business models to promote LH2 product as an effective way of transporting hydrogen or eventually as a fuel;
• There are no uniform standards and safety regulations for liquid hydrogen.

Proposals should also address the following economic and regulatory issues:

• The innovative concept should demonstrate a specific liquefaction cost at around 1 to 2 €/kg for a small scale unit;
• The project should define a suitable roadmap to prepare the deployment of low carbon liquid hydrogen solutions;
• The project should address safety aspects of supplies of liquid hydrogen (infrastructure aspects);
• Propose accurate business models for the scale-up of the industrial phase for commercialisation purposes; etc.
