Clean hydrogen production by non-membrane electrolysis

氢作为能源在使用点产生零碳排放。当从可再生资源电解生产时，生产中也是零碳排放。氢基解决方案的采用支持了英国到2050年将二氧化碳排放量减少80%的承诺，氢作为能源载体和能源储存具有巨大的潜力。氢气有广泛的新兴应用，即热量脱碳，为燃料电池提供动力，以取代运输和非道路机械中的内燃机，以及电力储存。在这些领域替代传统燃料还可以减少排放和噪音，改善当地环境，特别是空气质量。全球95%以上的氢气生产是通过蒸汽甲烷重整。这在很大程度上是工业工厂中的集中活动，并且通常在该过程中产生的二氧化碳不被捕获。如今，人们对使用非化石燃料的电力电解制氢产生了相当大的兴趣，并且这种兴趣正在增长。这不仅是无碳的，而且还提供了一个扩大生产规模以满足当地需求的机会，从而避免了从生产到使用点的长供应链。目前大多数电解槽的开发都是基于膜技术来分离电解产生的混合气体。Uniquely Clean Power Hydrogen正在开发一种创新的非膜电解槽和气体分离系统，该系统具有市场领先的效率和成本竞争力，具有所需的纯度水平以及世界级的可靠性和安全性。非膜解决方案避免了膜基解决方案的高初始成本和高维护和更换要求，并避免了质子交换电解槽所需的特殊金属。该项目将使电解槽技术取得快速进步，改善电解槽设计，安全性以及设计和建造过程。这项工作的成果将是一个制氢系统，该系统将用于传播学习，展示性能，并朝着这项创新技术的全面商业化迈进。

Hydrogen as energy generates zero carbon emission at point of use. When produced by electrolysis from renewable sources, there is also zero carbon emission in production. Uptake of hydrogen-based solutions supports the UK's commitment to cut CO2 emissions by 80% by 2050 and there is tremendous potential for hydrogen as an energy carrier and energy store. There is a wide range of emerging applications for hydrogen, namely decarbonising of heat, powering fuel cells to displace combustion engines in transport and non-road machinery, and in electricity storage. Replacing conventional fuels in these sectors also delivers emissions and noise reductions to improve the local environment, especially air quality.More than 95% of global hydrogen production is by steam methane reformation. This is largely a centralist activity in industrial plants and in general the carbon dioxide produced in the process is not captured.Nowadays there is considerable and growing interest in electrolysis for hydrogen production using electricity from non-fossil fuels. Not only is this carbon-free, but also provides an opportunity for scaling of production to meet local demands, thus avoiding long supply chains from production to point of use.Most of the current developments in electrolysers are based on membrane technologies to separate the mixed gases which are produced by electrolysis. Uniquely Clean Power Hydrogen are in the process of developing an innovative non-membrane electrolyser and gas separation system with the potential to deliver market-leading efficiencies and cost competitiveness, at the required levels of purity and with world-class levels of reliability and safety. The non-membrane solution avoids the high initial costs and high maintenance and replacement requirements of membrane-based solutions plus the avoidance of special metals which are characteristically required for Proton Exchange Electrolysers.This project will enable rapid progress to be made in electrolyser technology, improving electrolyser design, safety and design and build processes. The outcome of the work will be a hydrogen production system which will be used to disseminate learning, demonstrate performance and move towards full commercialisation of this innovative technology.
