Hydrogen-empowered Hydro-Electric Grids (HyHEG)

尼泊尔具有巨大的水电生产潜力。在全县范围内，建设微型水电(MHP)项目，为当地人民提供基本电力供应。由于功率的限制，这些孤岛微电网系统的性能受到了限制。虽然典型的径流发电机有恒定的额定(等于峰值)功率输出，但负荷需求波动远低于该峰值功率输出，不能超过它。这在很大程度上限制了电力的收获，并导致许多潜在能源被浪费。由于发电机电力有限，烹饪等电力密集型活动不能由电力供应覆盖，全国范围内的生物质用于烹饪，占尼泊尔总能源消耗的69%。接触生物质烹饪产生的烟雾是一种严重的健康风险，每年导致全球400万人过早死亡。这是一个典型的电力和能源匹配问题，对人口造成了致命的后果。该项目通过引入氢气生产、储存、分配和氢气烹饪来解决这种情况。与微型水力发电站连接后，氢气发电机能够将多余的电能转化为氢气，从而大幅增加能量收集。氢气随后被供应给当地家庭作为做饭的燃料气体，从而绕过了电力限制。这样，微型水电站的性能和效率大大提高，并使清洁可再生烹饪成为可能。

Nepal has a tremendous potential for hydroelectricity production. Across the county, micro hydroelectric power (MHP) projects are constructed to provide basic electricity supply to local people. These island microgrid systems are limited in their performance due to their power restrictions. While a typical run-of-the-river electric generator has a constant nominal (equals peak) power output, load demand fluctuates well below this peak power output and cannot surpass it. This grossly limits electricity harvest and causes much potential energy to go to waste. Power intensive activities such as cooking cannot be covered by electric supply due to generator power constraints, Country-wide biomass is resorted to for cooking, covering 69% of the total Nepali energy consumption. Exposure to smoke from biomass-based cooking is an acute health risk, giving rise to yearly 4 million premature deaths globally. This is a typical power and energy matching problem with fatal consequences for the population.This situation is combated in this project by introducing Hydrogen production, storage, distribution, and Hydrogen-based cooking. Connected to a micro hydroelectric power station, the Hydrogen generator is able to substantially increase the energy harvest by converting surplus electricity into Hydrogen. The Hydrogen subsequently is supplied to local homes as fuel gas for cooking, thus circumventing electric power limitations. In this way, performance and efficiency of the micro hydroelectric power station are substantially increased, and clean renewable cooking is made possible.
