Nh3 storage and transportation system and method

Abstract

A liquefaction heat pump system may have: a storage vessel configured to receive a liquified fuel from a piping grid network. A heat pump circuit may include sequentially at least a compression stage configured to compress the fuel, a heat pump stage configured to receive the compressed fuel from the compression stage, and to heat a coolant by removing heat from the compressed fuel by at least one heat exchanger. A pumping arrangement is configured to pump fuel from the storage vessel and/or from the heat pump circuit back to the piping grid network. A controller unit is configured for operating the liquefaction heat pump system such that fuel is liquefied and a coolant is heated by the heat pump circuit.
