HyJet - Hydrogen Jet Ignition for high performance rescue vessels

HyJet项目的目标是了解绿色氢在小型（低于24米）船舶（包括RNLI使用的船舶）先进发动机中的最佳使用情况，后者希望转向可持续、环保的推进解决方案。由于电池充电时间过长对船舶救援响应时间的潜在负面影响，这种船只的完全电气化是不可行的。这项工作的重点是比较绿色燃料在先进内燃机中的应用，该内燃机配备了特殊的“喷气点火”预燃室燃烧系统，无论单独使用还是作为混合动力增程器解决方案的一部分，该系统都能以类似柴油的零（或接近零）污染物效率运行。这项工作的重点是研究哪种形式的绿色氢燃料在RNLI和更广泛的24米以下船舶应用中最有效。要比较的燃料包括绿色氢、氨和甲醇。

The goal or project HyJet is to understand the optimum use of green hydrogen in advanced engines used in smaller (sub-24m) vessels including those used by the RNLI, who wish to switch to sustainable, environmentally friendly propulsion solutions. Full electrification of such vessels is not viable due to the potential negative impact of prolonged battery recharging times on vessel rescue response times. The work will focus upon a comparison of green fuels in an advanced internal combustion engine fitted with a special "Jet Ignition" pre-chamber combustion system capable of operating with diesel-like efficiency with zero (or near zero) pollutants when used alone or as part of a hybrid range extender solution. The focus of the work is on which form of fuel produced from green hydrogen will be the most effective across the RNLI and wider sub-24m vessel applications. The fuels to be compared include green hydrogen, ammonia and methanol.
