Like most countries, Rwanda has been confronted with the effects of a changing climate in recent years with floods resulting from heavy rainfalls. Rwanda pledged to reduce emissions relative to business as-usual scenario emission levels by 2030. Rwanda has a National Electrification Plan (NEP) to provide global access to electricity. In 2019, 51% of population had electricity. The NEP's target is to achieve 100% electricity access by 2024.In Rwanda, the sources of income of the community living in rural areas of Rwanda are agriculture and livestock. Gas motorbikes and bicycles are the common modes of transportation in these villages which tends to be expensive due to fuel price and bad roads. There is a need for electric motorbikes that are tough for African roads and have high autonomy of batteries. Unexpectedly, the main concern becomes the time and power rate of charge; it needs some kind of fast charging. This EVC-ESS is the perfect solution for it.OXTO, Gamma and Hobuka will form a consortium to build a project of an electric charging point for electric motorbikes and other types of electric vehicles in a rural area of Rwanda, connected to one of a mini-rural grid in Rwanda. The technical architecture will be composed of an innovative flywheel energy storage system (FESS) developed by OXTO and 2nd life battery packs extracted from EVs, a bidirectional AC/DC converter, an EV charger connected to the mini-grid where the system will be deployed during the phase 2.This project will, in phase 1, study how adding a transport electrification component to rural mini-grids will improve economically and environmentally lives of local populations.The energy storage system composed of flywheels & batteries will improve the energy efficiency of mini-grids and reduce waste of energy. This decarbonisation of transport will clearly reduce air and noise pollution. It will also reduce the risk of fuel leakage in supply chain and maintenance of gas motorbikes, a large source of water contamination.The project addresses several UN Sustainable Development Goals (SDG), especially the Sustainable Cities and Communities and Climate Action. The high quality of the professionals involved in this project, mostly owning UK University degrees, combined with the disruptive innovative FESS technology, is a great chance to promote the innovation capabilities and leadership of the UK in engineering, technology and education.

与大多数国家一样，卢旺达近年来也面临着气候变化的影响，洪水是由严重的干旱造成的。卢旺达承诺到2030年减少相对于"一切照旧“情景排放水平的排放量。卢旺达有一个国家电气化计划，为全球提供电力。2019年，51%的人口拥有电力。新能源计划的目标是到2024年实现100%的电力供应。在卢旺达，生活在农村地区的社区的收入来源是农业和畜牧业。天然气摩托车和自行车是这些村庄的常见交通方式，由于燃料价格和道路状况不佳，这些交通方式往往很昂贵。非洲需要一种电动摩托车，这种电动摩托车在非洲道路上很坚韧行驶，而且电池的自主性很高。出乎意料的是，主要的问题变成了充电的时间和功率;它需要某种快速充电。OXTO、Gamma和Hobuka将组成一个财团，在卢旺达农村地区建立一个电动摩托车和其他类型电动汽车的充电站项目，连接到卢旺达的一个小型农村电网。技术架构将由OXTO开发的创新飞轮储能系统（FESS）和从电动汽车中提取的第二寿命电池组，双向AC/DC转换器，连接到微型电网的电动汽车充电器组成，该系统将在第二阶段部署。研究如何在农村小型电网中增加运输电气化组件将改善当地人口的经济和环境生活。由飞轮和电池将提高小型电网的能源效率，减少能源浪费。交通的脱碳将明显减少空气和噪音污染。该项目还将减少供应链中燃料泄漏的风险，并减少天然气摩托车的维护，这是一个很大的水污染源。该项目涉及多个联合国可持续发展目标（SDG），特别是可持续城市和社区以及气候行动。参与该项目的高素质专业人员，大多拥有英国大学学位，加上颠覆性的创新FESS技术，是促进英国在工程，技术和教育方面的创新能力和领导地位的绝佳机会。
