One of our clients has cooled, liquefied gas stored in tanks. This works well. However, he would like to use the gas as fuel. This requires the liquefied gas to become gaseous again which can be achieved by heating the gas to above zero and evaporating it, costing an enormous amount in heat (= energy). Moreover, the client has to be able to immediately supply gas if there is a demand. The client is looking for an energy-saving and reliable solution.
