Abstract

The relatively slow advancement in biohydrogen research across Sub-Saharan Africa (SSA) countries, like Uganda, puts them at risk of ‘Copy-Pasting’ technologies designed for more advanced economies. This study uses a Multi-Factorial Design of Experiment to compare biohydrogen production profiles from three organic waste types (banana peel, pineapple peel and mixed peels), at four inoculum-to-substrate ratios (2:1, 1:1, 0.5:1 and 0.25:1), across three sites (Kampala, Uganda, and Leeds and York, United Kingdom). The results showed that the maximum biohydrogen yield was significantly higher in Leeds (116.3 mLH₂/gVS) and York (59.1 mLH₂/gVS) than Kampala (15.7 mLH₂/gVS). Moreover, the correlation analysis of key operating parameters showed vast inconsistencies in the performance profiles across the three sites, suggesting that data from one region cannot be used to inform technology uptake in a different region. A conscious approach to biohydrogen research and development is needed to enable technology adaptation to local resources across SSA.

选定果皮废弃物产氢的比较研究：区域和实验经验

撒哈拉以南非洲国家（如乌干达）的生物氢研究进展相对缓慢，这使它们面临为更发达经济体设计的“复制粘贴”技术的风险。本研究采用多因子实验设计，比较了三种有机废物类型（香蕉皮、菠萝皮和混合果皮）在四种接种物与底物比（2:1、1:1、0.5:1和0.25:1）下，在三个地点（乌干达坎帕拉和英国利兹和约克）产生生物氢的情况。结果表明，利兹（116.3 mLH2/gVS）和约克（59.1 mLH2/gVS）的最大生物氢产量显著高于坎帕拉（15.7 mLH2/gVS）。此外，关键操作参数的相关性分析显示，三个站点的性能概况存在巨大的不一致性，这表明一个地区的数据不能用于为不同地区的技术吸收提供信息。需要有意识地进行生物氢研究和开发，以使技术适应整个SSA的当地资源。

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
