Solar-Hydrogen Powered 100% Renewable Modular Mini-Grid (Solar-H2)

在地球仪的发达国家，我们认为可靠的能源供应是理所当然的。尽管发展中地区在能源获取方面取得了进展，但全球仍有7.7亿人无法获得现代能源服务[世界银行2020]，其中撒哈拉以南非洲地区有6亿人。电网连接和太阳能光伏系统改善了撒哈拉以南非洲城市人口的能源获取，74%的人现在受益于电力供应。然而，在撒哈拉以南非洲的农村地区，只有26%的人口能够获得电力[WEO 2019数据库，IEA 2020]。这些农村地区被剥夺了清洁、可靠和具有成本效益的能源，无法为家庭、商业和社区建筑提供能源。这导致了对生物质燃料的依赖（造成危及生命的健康危害和破坏生态系统）或昂贵的污染柴油发电厂[乐施会，2020]。独立系统和清洁的微型电网已被确定为解决方案，国际能源署预测，到2030年，它们将占农村连接的70%[ADGB，2020]。在这个项目中，Sun Harvester将与肯尼亚合作伙伴合作，希望光明未来中心（当地代理，非政府组织希望国家）设计，开发和现场测试负担得起的社区微型电网解决方案，由太阳能电池板供电。合作伙伴将直接与当地社区合作，解决与设计和最终用户需求相关的所有性别和社会包容问题。我们将进一步开发独立的即时电网（IG）模块化储能技术，用于小型电网。我们的微型电网解决方案将是可扩展的，因此我们可以实现足够的电力供应能力，为整个社区供电。我们将用氢燃料电池技术取代柴油发电机备用，以提供100%可再生的微型电网解决方案。消除柴油带来广泛的环境、燃料节约、供应安全和健康益处。例如，目前撒哈拉以南非洲地区发电机排放的二氧化碳相当于2200万辆汽车行驶在路上。\[The Dirty Footprint of the Broken Grid，World Bank 2019\].Sun Harvester的解决方案将微型电网的平准化电力成本（LCOE）从0.39美元/千瓦时\[Irena，2020\]降低到0.24美元/千瓦时。可通过以下方式实现成本节约：安装简便、更换单个电池以及电池监控/管理以延长使用寿命。此外，我们的模块化设计允许正确调整小型电网安装的规模，将入门级CAPEX成本从c.我们的解决方案在经济上是可行的，专门设计用于肯尼亚和撒哈拉以南非洲的偏远农村地区。这将为所有人提供负担得起的、安全的能源供应，为撒哈拉以南非洲风险最大和最贫困的社区带来好处。

In developed countries across the globe, we take reliable energy access for granted. Although progress on energy access is being made in developing regions, 770m people worldwide are still living without access to modern energy services \[World Bank 2020\], including 600m in Sub-Saharan Africa.Grid connection and solar PV systems have improved energy access for Sub-Saharan African urban populations, with 74% now benefiting from electricity access. However, in rural Sub-Saharan Africa, only 26% of the population have access to electricity \[WEO2019 database, IEA 2020\]. These rural areas are deprived of clean, reliable, and cost-effective energy to supply domestic, commercial and community buildings. This leads to a reliance on biomass fuels (creating life-threatening health hazards and decimating ecosystems) or expensive, polluting diesel plants \[Oxfam, 2020\].Stand-alone systems and clean mini grids have been identified as a solution, with IEA predicting they will make up 70% of rural connections by 2030 \[ADGB, 2020\].In this project, Sun Harvester will work with Kenyan partners, Hope Bright Future Centre (local agent, NGO Hope for the Nations) to design, develop and field test an affordable community mini-grid solution, powered by solar panels. Working directly with local communities, the partners will address all the gender and social inclusion aspects related to design and end-user needs.We will further develop our stand-alone Instant Grid (IG) modular energy storage technology for use in a mini-grid. Our mini-grid solution will be scalable, so we can achieve enough power supply capacity to supply entire communities. We will replace diesel generator back-up with hydrogen fuel cell technology to deliver a 100% renewable mini-grid solution. Elimination of diesel brings extensive, environmental, fuel saving, security of supply and health benefits. For example, carbon dioxide currently emitted by generators in Sub-Saharan Africa is equivalent to 22m passenger vehicles on the road. \[The Dirty Footprint of the Broken Grid, World Bank 2019\].Sun Harvester's solution will reduce mini-grid Levelised Cost of Electricity (LCOE) from $0.39/kWh \[Irena, 2020\] to $0.24/kWh. Cost savings are achievable through: easy installation, replacement of individual battery cells and battery monitoring/management for increased lifetime. Furthermore, our modular design allows correct sizing of mini-grid installations, reducing entry level CAPEX costs from c.$100k to $10k.Our solution will be economically viable and specifically designed for deployment in remote, rural areas of Kenya, and sub-Saharan Africa. This will unlock affordable, secure, energy access for all, bringing benefits to sub-Saharan Africa's most at-risk and impoverished communities.
