A new zero-carbon emissions LNG carrier design includes an ammonia-fuelled gas turbine and a heat recovery system using supercritical CO2.

ABS has issued two approvals in principle (AiP) related to the design of an LNG carrier equipped with an ammonia-fuelled gas turbine. Along with an AiP for the vessel design itself to Hanwha Ocean, ABS also issued an AiP to Hanwha Power Systems for its supercritical carbon dioxide (sCO2) power system.

The 174,000 cbm vessel would be the world’s first carbon emission free LNG carrier. The vessel can use ammonia and natural gas separately or simultaneously as fuel. If only ammonia is used as fuel, no carbon gas is emitted.
