Hitachi, ASCO to develop CO2 liquefaction plant for ‘ground-breaking’ Swiss energy project | Carbon Dioxide

A new liquefaction plant is to be installed by energy partners Hitachi Zosen Inova (Hitachi) and ASCO Carbon Dioxide Ltd (ASCO) to separate and liquefy renewable carbon dioxide (CO2) at a Swiss biogas plant.

To prevent CO2 from being released into the atmosphere, the ‘state-of-the-art’ facility will capture the CO2 that is removed during biogas to biomethane upgrading before the gas is filtered and dehydrated under high pressure.

With a processing capacity of 4,000 tonnes per year, the plant will produce biogenic CO2 to be used for a…
