Ship Transport of CO2
ieaghg.orgCO2 liquefaction Most CO2 capture processes produce gaseous CO2 at atmospheric or slightly elevated pressure. If a CO2 capture plant was built close to a port the CO2 would be fed directly to a liquefaction plant, where it would be compressed, cooled using an external refrigeration circuit and then partially depressurised to provide final cooling.

Hydrogen Delivery Liquefaction and Compression
www1.eere.energy.gov6 Hydrogen Liquefaction ¾There are 10 hydrogen liquefaction plants in North America zTrain size ranges from 6 to 35 TPD (5,400 to 32,000 kg/day) ¾In the 1960’s, liquid hydrogen plants were built to support the Apollo program. Today, liquid hydrogen is used to reduce the cost of hydrogen distribution. zDelivering a full tube trailer of hydrogen to a customer results in a
Ammonia: zero-carbon fertiliser, fuel and energy store
royalsociety.orgstore in bulk, it requires liquefaction either by compression to 10 times atmospheric pressure or chilling to -33°C. In this state, the energy density of ammonia is about 3 kWh/litre which is less than but comparable with fossil fuels (Figure 4). Hydrogen by comparison is also a gas at atmospheric pressure and room temperature.
