Net Zero Ports of the Future: Demonstrating the Integration of Green Hydrogen Shore Power with Water Reuse

港口是英国经济的重要组成部分，每年贡献75亿英镑，支持全国约119，000个就业岗位。尽管预计将在港口部署替代燃料，但到2050年，港口的总电力需求将大幅增加。英国交通部估计，到2050年，英国港口的年总电力需求将从2016年的20吉瓦时上升到250吉瓦时左右，其中海岸电力的需求将达到200吉瓦时。此外，出生时的排放量占船舶碳排放量的约16%，NOx的13%和PM10的11%。Forth Ports的愿景是创建苏格兰最大的可再生能源中心，减少碳足迹和船东的足迹。该港口旨在重新工业化苏格兰中部，并带来多达50，000个高质量的绿色工作岗位。预计该港口的船只数量将增加，其中游轮数量将增加50%，这将为英国带来巨大的经济效益。因此，港口的电力需求和脱碳需求对海事部门来说是一个重大的挑战和机遇。继清洁海事示范比赛第二轮可行性研究成功交付之后，HyBunk，Targe Towing（Forth Ports子公司）将与Waterwhelm合作，Logan Energy和PlusZero将在利斯港提供最先进的示范系统，用于生产海岸电力所需的氢气。Seafield废水处理厂（WWTW）紧邻利斯港，是Waterwhelm采用低碳足迹、废热驱动的正向渗透技术进行水再利用和海水淡化的地方。Waterwhelm将使用来自Seafield WWTW的经处理的废水，这些废水通常被排入大海，再加上PlusZero零排放氢内燃机（HICE）发电机的余热，为Logan Energy的电解槽生产淡水。生产的氢气将用于PlusZero的HICE发电机，在高峰时段为海岸电力生产按需电力，作为化石燃料（柴油）发电机的替代品。这将使利斯港重新成为海事部门新创新技术的可再生中心。利用PlusZero HICE的余热和WWTW的处理后废水进行处理是一种循环经济，零废物的方法，展示了技术和相邻行业如何相互支持，有效地生产氢气用于港口脱碳，并为英国的净零目标做出贡献。

Ports are a significant component of the UK economy, contributing £7.5 billion annually and supporting around 119,000 jobs across the country. Despite anticipated deployment of alternative fuels at ports, their total electricity demand is to increase significantly by 2050\. The UK's Department for Transport estimates that total annual electricity demand at UK ports will rise from 20GWh in 2016 to around 250GWh by 2050, with shore power contributing to 200GWh of demand. Further, emissions at birth represent ~16% of ships' carbon emissions, 13% of NOx and 11% of PM10\. The vision of Forth Ports is to create Scotland's largest renewable hub, reducing carbon footprint and the footprint of ship owners. The port aims to re-industrialise central Scotland and bring up to 50,000 high-quality green jobs. The port is expected to see an increase in vessels, including a 50% rise in cruise ships, with significant economic benefits to the UK. Thus, power demand and need for decarbonisation at ports represents a major challenge and opportunity to the maritime sector.Following on from a successfully delivered Clean Maritime Demonstration Competition Round 2 feasibility study, HyBunk, Targe Towing (Forth Ports subsidiary) will partner with Waterwhelm, Logan Energy and PlusZero to deliver a state-of-the-art demonstrator system at the Port of Leith for the production of hydrogen for shore power. Seafield wastewater treatment works (WWTW) is situated immediately next to Port of Leith and is where Waterwhelm has its low carbon footprint, waste heat powered forward osmosis technology for water re-use and desalination. Waterwhelm will use treated wastewater from Seafield WWTW, that is ordinarily ejected into the sea, combined with waste heat from PlusZero's zero emissions hydrogen internal combustion engine (HICE) generator to produce freshwater for Logan Energy's electrolyser for hydrogen production. The produced hydrogen will be used in PlusZero's HICE generator to produce on-demand electricity for shore power at peak times as an alternative to the fossil fuel (diesel) powered generators. This will re-establish the Port of Leith as a renewable hub for new innovative technologies for the maritime sector. The use of waste heat from PlusZero's HICE and treated wastewater from WWTW for the process is a circular economy, zero waste approach that shows how technologies and adjacent industries can support each other to efficiently produce hydrogen for decarbonisation of ports and contribute to the UK net-zero goals.
