Solar-hydrogen microgrid with dedicated fresh-water production for Bandjoun, Cameroon

对包括荒漠化在内的气候变化的日益关切，要求为世界上最不发达地区制定可获得的清洁能源解决方案。将这些地区的大量太阳能资源转化为清洁的氢（H2）燃料和淡水，提供了一个有效的解决方案。这对性别平等和社会包容产生了重大影响，因为收集木材作为烹饪燃料和取水是这些社会中妇女的负担。技术进步正在降低氢气生产的成本，使其越来越具有吸引力（到2030年便宜40%[IRENA，2020年]）。英国和国外的公众要求改变政策，作为回应，33个国家已经宣布进入气候紧急状态[CEDAMIA，2021]。可再生能源的成本降低将推动未来在可再生能源丰富的地区实施分散式绿色氢气生产系统。该项目的目标是为非洲太阳能丰富的城市地区开发创新的能源解决方案。该系统将集成模块化技术和“即插即用”方法，利用间歇性太阳能发电生产绿色氢气和清洁水。a）使用氢作为能量储存介质，以提供昼夜不间断的电力供应B）为社区提供额外的清洁水c）无碳燃料取代石油衍生物，用于取暖和电器d）e）生产氢气作为烹饪燃料和淡水，以减轻女性的负担。该项目是与位于喀麦隆Bandjoun的太阳能公司Universo和Bandjoun地方当局合作进行的，以展示一个明确的应用实例。有四个关键创新：1）开发一种新的能量流和能量存储技术，用于使用间歇性太阳能电解水; 2）在高TRL（= 7）下使用主要设备部件的代表性数学模型，这将使系统能够快速地进行演示和开发3）设计一个具有即插即用功能的模块化系统，以最大限度地降低复杂性，并减少对外部专业知识的长期管理需求。4）实施一种有效的方法来储存和运输氢气，用于城市地区的应用。成功的项目实施将释放和降低未来在Bandjoun和类似地区的投资风险。这将为BPP和Universo带来新的收入。

Increasing concerns about climate change, including desertification, requires the development of accessible clean energy solutions for the world's least developed regions. The conversion of the large resource of solar energy in such regions into clean Hydrogen (H2) fuel and fresh water, offers an effective solution. This has a significant impact on gender equality and social inclusion since the collection of wood for cooking fuel and water collection is a burden on women in these societies.Technological improvements are reducing the cost of H2 production, making it increasingly attractive (40% cheaper by 2030 \[IRENA, 2020\]). The public in the UK and abroad are demanding policy changes, and in response, 33 countries have declared a climate emergency \[CEDAMIA, 2021\]. Cost reduction of renewable energy sources will drive the future implementation of decentralised Green H2 production systems in places with abundant renewable energy.The objective of this project is to develop an innovative energy solution for urban areas in Africa characterised by abundant solar energy. The system will integrate modular technologies and a 'Plug & Play' approach to Green H2 and clean water production using intermittent solar power sources.The benefits for the local community are: a) use hydrogen as an energy storage medium to provide continuous power supply throughout the day and night b) additional clean water available to the community c) carbon-free fuel replacing oil-derivatives for heating and electrical appliances d) reducing congestion on the grid with a decentralised power system e) generate hydrogen as cooking fuel and fresh water to alleviate burdens on the female gender.This project is conducted in collaboration with the solar energy company Universo, based in Bandjoun, Cameroon and the local authorities of Bandjoun to demonstrate a clear example application.There are four key innovations: 1) develop a novel power flow and energy storage technique for the electrolysis of water using intermittent solar power; 2) use of representative mathematical models of major equipment components at high TRLs (= 7) that will enable the system to be rapidly moved to demonstration and exploitation 3) design a modular system with Plug & Play features to minimise complexity and the need for external expertise to manage it over the long-term 4) implement an effective way of storing and transporting hydrogen for applications in urban areas.Successful project implementation will unlock and de-risk future investments in Bandjoun and similar regions. It will generate new income for BPP and Universo.
