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.

尼泊尔拥有巨大的水力发电潜力。在整个县，微型水力发电（MHP）项目的建设，为当地人民提供基本的电力供应。这些岛屿微电网系统由于其功率限制而在性能上受到限制。虽然典型的径流式发电机具有恒定的额定（等于峰值）功率输出，但负载需求波动远低于峰值功率输出，并且不能超过峰值功率输出。这严重限制了电力收获，并导致大量潜在能量浪费。由于发电机功率有限，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，占尼泊尔能源消耗总量的69%。暴露于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，会给人们带来致命的后果。本项目通过引入氢气生产、储存、分配和氢基烹饪来应对这种情况。氢气发生器连接到微型水力发电站，能够通过将多余的电力转化为氢气来大幅增加能源收获。氢气随后被供应给当地家庭作为做饭的燃料气体，从而规避了电力限制。通过这种方式，微型水力发电站的性能和效率大大提高，并使清洁的可再生烹饪成为可能。
