Dissecting the exergy balance of a hydrogen liquefier: Analysis of a scaled-up claude hydrogen liquefier with mixed refrigerant pre-cooling
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 Temperature Applications for CO2 Capture in Hydrogen Production
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...
Concept of hydrogen fired gas turbine cycle with exhaust gas recirculation: Assessment of process performance
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 NOx emissions at the expense of a significant...
Large-scale production and transport of hydrogen from Norway to Europe and Japan: Value chain analysis and comparison of liquid hydrogen and ammonia as energy carriers
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...

Techno-economic comparison of three technologies for precombustion CO2 capture from a lignite-fired IGCC
This paper compares the techno-economic performances of three technologies for CO2 capture from a lignite-based IGCC power plant located in the Czech Republic: (1) Physical absorption with a Rectisol-based process; (2) Polymeric CO2-selective membrane-based capture; (3) Low-temperature capture...
