Abstract

A fuel system for a hydrogen fuelled gas turbine engine (201). The fuel system comprises a main hydrogen fuel line (206) configured to provide hydrogen fuel to a combustor (203) of the gas turbine engine (201) and a closed loop heat exchange fluid line (207) comprising a heat exchange fluid. The fuel system further comprises a first heat exchanger (208) configured to exchange heat between gas turbine engine compressor bleed air and heat exchange fluid in the heat exchange fluid line (207), a second heat exchanger (209) downstream of the first heat exchanger (208) in heat exchange fluid flow configured to exchange heat between the heated heat exchange fluid and hydrogen in the main hydrogen fuel line, and a third heat exchanger (215) downstream in main hydrogen fuel flow of the second heat exchanger (209) in main hydrogen fuel flow configured to exchange heat between a further engine fluid and heated hydrogen fuel.
