HyDeploy项目是英国第一个实际项目，证明氢气可以安全地混合到天然气分配系统中，而不需要更换电器和相关的中断。该项目由Ofgem的网络创新大赛资助，由Cadent Gas、Northern Gas Networks、进步能源有限公司、基尔大学(Keele University)、健康与安全实验室和ITM Power合作完成。Cadent和Northern Gas Networks是该项目的天然气分配网络赞助商。基尔大学是主办地，提供气体分配网络，接收氢气混合。基尔大学是英国最大的校园大学。健康与安全实验室提供科学实验室和实验专业知识。ITM Power提供产生氢气的电解槽。进步能源有限公司是项目开发商和项目经理。HyDeploy被构造为三个不同的阶段。首先是一项广泛的技术计划，以建立必要的详细证据基础，以支持向卫生与安全行政部门申请豁免《气体安全(管理)规例》(GS(M)R)附表3，允许以20摩尔%的比例注入氢气。这是允许氢气混合到天然气供应中超过英国目前0.1摩尔%的限制所必需的。第二阶段包括建造电解槽和电网进入单元，以及必要的管道和阀门，以便将氢气混合并注入基尔大学的气体分配网络，并确保在注入之前对操作员进行所有必要的培训。第三阶段是审判本身，定于2019年夏天开始，持续约10个月。试验阶段还提供了开展与业务网络有关的进一步试验活动的机会，以支持全面部署混合气体的途径。HyDeploy的成果主要是建立了初步的证据基础，即氢气可以混合到英国运营的天然气网络中，而不会对客户造成干扰，也不会损害最终用户的安全。如果规模化部署，20摩尔%的氢气混合将释放29TWh pa的脱碳热，并为更深层次的节约提供路线图。在全国范围内推广20摩尔%的氢气混合燃料，相当于减少了250万辆汽车上路。HyDeploy是英国一个开创性的项目，旨在通过氢气部署实现天然气电网的脱碳，并将为氢载体在技术、操作和监管方面的先例提供第一块垫脚石。
The HyDeploy project is the UK’s first practical project to demonstrate that hydrogen can be safely blended into the natural-gas distribution system without requiring changes to appliances and the associated disruption. The project is funded under Ofgem’s Network Innovation Competition and is a collaboration between Cadent Gas, Northern Gas Networks, Progressive Energy Ltd, Keele University (Keele), Health & Safety Laboratory and ITM Power. Cadent and Northern Gas Networks are the Gas Distribution Network sponsors of the project. Keele University is the host site, providing the gas-distribution network, which will receive the hydrogen blend. Keele University is the largest campus university in the UK. Health & Safety Laboratory provides the scientific laboratories and experimental expertise. ITM Power provides the electrolyser that produces the hydrogen. Progressive Energy Ltd is the project developer and project manager. HyDeploy is structured into three distinct phases. The first is an extensive technical programme to establish the necessary detailed evidence base in support of an application to the Health & Safety Executive for Exemption to Schedule 3 of the Gas Safety (Management) Regulations (GS(M)R) to permit the injection of hydrogen at 20 mol%. This is required to allow hydrogen to be blended into a natural-gas supply above the current British limit of 0.1 mol%. The second phase comprises the construction of the electrolyser and grid entry unit, along with the necessary piping and valves, to allow hydrogen to be mixed and injected into the Keele University gas-distribution network and to ensure all necessary training of operatives is conducted before injection. The third phase is the trial itself, which is due to start in the summer of 2019 and last around 10 months. The trial phase also provides an opportunity to undertake further experimental activities related to the operational network to support the pathway to full deployment of blended gas. The outcome of HyDeploy is principally developing the initial evidence base that hydrogen can be blended into a UK operational natural-gas network without disruption to customers and without prejudicing the safety of end users. If deployed at scale, hydrogen blending at 20 mol% would unlock 29 TWh pa of decarbonized heat and provide a route map for deeper savings. The equivalent carbon savings of a national roll-out of a 20-mol% hydrogen blend would be to remove 2.5 million cars from the road. HyDeploy is a seminal UK project for the decarbonization of the gas grid via hydrogen deployment and will provide the first stepping stone for setting technical, operational and regulatory precedents of the hydrogen vector.
