全球氢经济目前正处于起步阶段。预测表明，到2050年，氢可以提供全球10%的能源。英国气候变化委员会（CCC）预测，到2050年，英国将消耗220 TWh.H2/年，其中95 TWh将来自电解。到2050年，英国的电力需求预计将翻一番，达到600 TWhe/年，其中大部分来自海上风电（OSW）。在英国周围有丰富的风力资源的海洋区域，但远离人口中心。以传统方式开发这些风力资源需要对电力传输系统进行昂贵的升级;直接生产氢气提供了一种替代能源载体。从OSW生产氢气似乎是不可避免的，并且在某些地区具有潜在的经济优势。这份报告从科克大学的工作准备，并提出了一个510兆瓦的OSW，由34个固定的底部，15兆瓦的风力涡轮机发电机（WTG）。采用的主要指标是氢的平准化成本（LCoH）。对电解槽容量、贴现率（DR）和电解槽效率的灵敏度进行了检查。基础模型返回的LCoH为£5.69/Kg.H2，DR等于6%。
The global hydrogen economy is currently at inception. Forecasts suggest that hydrogen could deliver 10% of global energy by 2050. The UK Climate Change Committee (CCC) forecast the UK will consume 220TWh.H2/yr in 2050 of which 95TWh will be derived from electrolysis. UK electrical power demand is expected to double to >600TWhe/yr by 2050, with the majority coming from offshore wind (OSW). Around the UK there are marine regions rich in wind resource, but remote from centres of population. Exploiting these wind resources conventionally would require expensive upgrades to the electrical transmission system; direct production of hydrogen offers an alternative energy vector. Hydrogen production from OSW appears an inevitability, and in certain regions potentially financially advantageous. This report picks up from work prepared by the University of Cork, and presents a 510MW OSW, consisting of 34 fixed bottom, 15MW Wind Turbine Generators (WTG). The primary metric adopted is the Levelised Cost of Hydrogen (LCoH). Sensitivities for electrolyser capacity, Discount Rate (DR), and electrolyser efficiency were examined. The base model returned an LCoH of £5.69/Kg.H2 with a DR equal to 6%.
