HyJet - Hydrogen Jet Ignition for high performance rescue vessels

HyJet 的目标或项目是了解小型（24m 以下）船舶所使用的先进发动机中绿色氢的最佳使用方式，其中包括 RNLI 使用的船舶，他们希望改用可持续、环保的推进解决方案。由于电池充电时间过长会对船舶救援响应时间产生潜在的负面影响，此类船舶的完全电气化是不可行的。这项工作将重点对配备特殊“喷射点火”预燃室燃烧系统的先进内燃机中的绿色燃料进行比较，当单独使用或作为混合增程解决方案的一部分时，该系统能够以类似柴油的效率运行，污染物为零（或接近零）。这项工作的重点是，哪种形式的绿色氢燃料在 RNLI 和更广泛的 24m 以下船舶应用中最有效。进行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.
