In the literature, different energy carriers are proposed in future long-distance hydrogen value chains. Hydrogen can be stored and transported in different forms, e.g. as compressed dense-phase hydrogen, liquefied hydrogen and in chemically bound forms as different chemical hydrides. Recently...

For liquid hydrogen (LH2) to become an energy carrier in energy commodity markets at scales comparable to for instance LNG, liquefier capacities must be scaled up several orders of magnitude. While state-of-the-art liquefiers can provide specific power requirements down to 10 kWh/kg, a long-term...

Low-carbon hydrogen is considered as one of the key measures to decarbonise continental Europe and Japan. Northern Norway has abundant renewable energy and natural gas resources which can be converted to low-carbon hydrogen. However, Norway is located relatively far away from these markets and...

The recent development of the protonic membrane reformer (PMR) technology allows an energy efficient hydrogen production from natural gas. To liquefy and separate CO₂ from the retentate gas of the PMR, various low temperature processes are modelled and compared. The optimization results indicate...

High hydrogen content fuels can be used in gas turbine for power generation with CO₂ capture, IGCC plants or with hydrogen from renewables. The challenge for the engine is the high reactive combustion properties making dilution necessary to mitigate NO_x emissions at the expense of a significant...
