4、uctionThe challenge of maritime decarbonisation is not that it is happening,but that it needs to happen so quickly.The evolution of sail to its heyday of the great tea clippers took centuries,and the transition to coal-powered steam ships was driven by greater supply chain mobility and speed.The arr

5、ival of diesel-fuelled engines led to a new type of ship propulsion and power generation,but this has taken close to one hundred years to evolve to where they are today.Each shift had a dramatic impact on the cost,speed and efficiency of shipping.The energy transition that the maritime industry face

6、s today is distinct from those earlier evolutions.It is not driven solely by technological advances or economics,but by an environmental imperative,increasingly underscored by social pressure,policy,and regulatory demands to reduce emissions.Decisions are being made today with some commercial uncert

1. **氢能作为船用燃料的潜力与挑战**:氢能可实现近零温室气体排放,但存在能量密度低(液氢体积能量密度仅为HFO的4.52%)、易燃(燃点范围4%-75%)、需超低温储存(-253℃)等挑战。 2. **技术成熟度**:氢内燃机(ICE)和燃料电池(FC)技术处于不同发展阶段,燃料电池投资准备度(IRL)较低(6级),需政策支持以加速商业化。 3. **法规驱动**:欧盟Fit for 55政策(如EU ETS、FuelEU Maritime)及IMO 2050净零目标推动氢能应用,但 bunkering 标准仍在制定中。 4. **经济性**:当前绿氢成本高(液氢储存成本达5万欧元/吨),燃料电池初始投资高(3800-5400美元/kW),预计2038年后降至1000美元/kW。 5. **安全与培训**:需解决氢脆、泄漏检测及船员培训问题,LR发布氢燃料船舶规范,IMO预计2026年通过氢能安全指南。
