An innovative hybrid infrastructure system delivering both electric and hydrogen for vessel fast charging/refuelling using off grid renewable energy and onsite wastewater.

在向低碳航运过渡的过程中，目前正在研究多种低碳燃料。今后船舶可能会根据其作业要求，如航行时间或所载货物，使用不同类型的燃料。这给港口运营商在开发基础设施方面带来了困难，这些基础设施可以为船舶提供多种不同的燃料类型，这意味着对基础设施的重大投资，而基础设施往往非常具体。目前正在广泛开发的两种技术是电动和氢气船舶，电动侧重于短途“绿色走廊”旅行，氢气用于提供更长时间的旅行。由于国家电网的限制，目前很难开发电网连接，这不仅对电动船舶充电造成了困难，在这个项目中，HydroStar，Waterwhelm和伦敦南岸大学的合作团队将开发一个创新的基础设施系统，该系统可以使用离网可再生能源和现场废水在混合系统中提供电力和氢气船舶快速充电/加油。这使港口能够发展低碳基础设施，从整体角度供应两种燃料。通过金属氢化物储氢容器系统与燃料电池和电池系统相结合，实现两种燃料的运输。所产生的电力可以直接用于充电和电池存储，或者用于氢的产生和存储。氢气可以快速释放，用于快速加油或通过燃料电池快速发电。氢气的产生将通过现场废水的净化和处理来促进，利用金属氢化物和电解系统的废热为处理过程提供动力，并消除对水管基础设施的依赖。

In the transition to low carbon shipping, multiple low carbon fuels are currently being investigated. It is likely that in the future different fuel types will be used by ships depending on their operational requirements, such as voyage duration or cargo being carried. This poses a difficulty for port operators in the development of infrastructure which can supply multiple different fuel types to ships, representing significant investments for infrastructure which is often very case specific.Two technologies currently being developed extensively are electric and hydrogen vessels, with electric focussing on short 'green corridor' trips, and hydrogen for supplying longer duration trips. Electrical grid connections are currently very difficult to develop due to National Grid constraints, which poses a difficulty not only for electric vessel charging.Within this project, the collaboration team of HydroStar, Waterwhelm and London South Bank University will develop an innovative infrastructure system which can deliver both electrical and hydrogen vessel fast charging/refuelling in a hybrid system using off grid renewable energy and onsite wastewater. This enables ports to develop their low carbon infrastructure to supply both fuel types from a holistic standpoint.Delivery of both fuel types is achieved through a system of metal hydride hydrogen storage vessels in combination with a fuel-cell and battery system. The electricity generated can either be used directly in electrical charging and battery storage, or alternatively in hydrogen generation and storage. Hydrogen can be released quickly either for fast refuelling or fast generation of electricity through the fuel-cell. Generation of hydrogen will be facilitated through the purification and treatment of wastewater onsite, using waste heat from the metal hydride and electrolyser systems to power the treatment process and remove the reliance on water main infrastructure.
