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。未来，船舶很可能会根据其操作要求，例如航程时间或所运载的货物，使用不同的燃料。这给港口运营商带来了开发基础设施的困难，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大量投资，这往往非常具体。目前正在广泛开发的两项技术是电动和氢气船，电动重点是短途“绿色走廊”旅行，而氢气则用于提供更长时间的旅行。由于国家电网的限制，目前电网连接的开发非常困难，这不仅给电动容器充电带来了困难。在这个项目中，水星公司、Water Spellm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，该系统可以在一个利用离网可再生能源和现场废水的混合系统中提供电力和氢气容器的快速充电/加油。这使港口能够发展其低碳基础设施，从整体上供应这两种燃料。这两种燃料的输送是通过金属氢化物储氢容器系统以及燃料电池和电池系统来实现的。所产生的电力可以直接用于充电和电池存储，或者替代地用于氢气的产生和存储。氢可以快速释放，用于快速加油或通过燃料电池快速发电。通过现场净化和处理废水，利用金属氢化物和电解槽系统的废热为处理过程提供动力，并消除对主要供水基础设施的依赖，将促进氢气的产生。

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.
