Hydrogen-empowered Hydro-Electric Grids (HyHEG)

尼泊尔有巨大的水力发电潜力。在全县建设微型水电项目，为当地居民提供基本电力供应。由于功率的限制，这些岛屿微电网系统的性能受到限制。而一个典型的河流发电机有一个恒定的标称（等于峰值）功率输出，负载需求波动远低于这个峰值功率输出，不能超过它。这严重限制了电力的收集，并导致大量潜在能源被浪费。由于发电机功率的限制，电力供应无法覆盖烹饪等电力密集型活动。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，全球每年有400万人过早死亡。这是一个典型的权力和能量匹配问题，会给人口带来致命的后果。在这个项目中，通过引入氢气的生产、储存、分配和氢基烹饪来解决这种情况。连接到一个微型水力发电站，氢气发生器能够通过将多余的电力转化为氢气来大幅增加能量收获。氢气随后被供应给当地家庭作为烹饪燃料，从而绕过了电力限制。这样大大提高了微型水力发电站的性能和效率，使清洁的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.
