A new study by researchers at\u00a0<\/span>Johns Hopkins University\u2019s<\/a>\u00a0<\/span>Renewable Energy and Equity Worldwide Laboratory<\/a>\u00a0<\/span>(RENEW), together with collaborators with partners in Kenya found that green hydrogen in Kenya may be most valuable when integrated with the national power grid rather than developed solely through standalone renewable projects.<\/p>\n

Green hydrogen is made by splitting water into hydrogen and oxygen using renewable electricity\u2014typically wind or solar\u2014via electrolysis. Because its production emits no carbon dioxide, it is widely regarded as a key tool in combatting climate change.<\/p>\n

\u201cNew industries like green hydrogen are often treated as either a guaranteed breakthrough or prohibitively expensive,\u201d said\u00a0<\/span>Xi Xi<\/a>, a PhD student in\u00a0<\/span>civil and systems engineering<\/a>\u00a0<\/span>and the study\u2019s lead author. \u201cThe real question is whether green hydrogen is produced in a way that supports broader development goals.\u201d<\/p>\n

The paper\u2014published in\u00a0<\/span>Environmental Science & Technology<\/em><\/a>\u00a0<\/span>and titled \u201cReducing Power System Costs in LMICs through Grid-Connected Green Hydrogen: Evidence from Kenya<\/a>,\u201d\u2014shows that grid-connected electrolyzers can be at least as affordable as standalone hydrogen plants, but have the added benefit of lowering overall electricity system costs. In other words, green hydrogen may be more valuable than commonly assumed when it is designed not only as a new industrial product, but also as a flexible part of the power system.<\/p>\n

The study was prompted in part by Kenya\u2019s domestically focused hydrogen strategy, which contrasts with many projects elsewhere in Africa that have been criticized for prioritizing exports to Europe. By emphasizing local industry, Kenya offers a compelling case for how green hydrogen can support national development goals rather than external demand.<\/p>\n

To date, much of Kenya\u2019s policy discussion has focused on hydrogen as a standalone industrial product made by dedicated renewable generation. The RENEW Lab\u2019s study points to a broader opportunity: when hydrogen production is connected to the grid and operated flexibly, it can help absorb surplus renewable electricity, improve system efficiency, and support lower-cost power across the economy.<\/p>\n

\u201cIn Kenya, we found that the value of hydrogen as a flexible load has been seriously underestimated,\u201d Xi said. \u201cWhen electrolyzers are connected to the grid, they can be at least as affordable as standalone projects while also helping reduce electricity costs across the system.\u201d<\/p>\n

Using a county-level, multi-nodal power system model with a customized electrolyzer module, the researchers examined how hydrogen production affects electricity costs, grid flexibility, and renewable energy deployment under a range of scenarios. They also tested different cost assumptions, reflecting the early-stage nature of electrolyzer technology.<\/p>\n

\u201cThe findings demonstrate the potential of green hydrogen in optimizing operation and utilization of the Kenyan power grid when supported by the co-benefits derived from production of fertilizer and other derivatives that contribute to the country\u2019s economic growth,\u201d said\u00a0<\/span>Boniface Kinyanjui<\/a>, Acting Director of Electricity and Renewable Energy at\u00a0<\/span>Kenya\u2019s Energy and Petroleum Regulatory Authority<\/a>\u00a0<\/span>(EPRA) and a co-author of the study.<\/p>\n

Daniel Kammen<\/a>, the Bloomberg Distinguished Professor of Energy and Climate Justice and the director of RENEW who was a co-author of the study, believes Kenya will not realize the full benefits of integrating green hydrogen into its grid until there is a greater global commitment to the technology.<\/p>\n

\u201cThe domestic need for hydrogen in Kenya could be useful, but it is unlikely enough to warrant a major investment unless the global green hydrogen market makes exports profitable,\u201d said Kammen, who is also a core researcher with the\u00a0<\/span>Ralph O\u2019Connor Sustainable Energy Institute<\/a>. \u201cOur findings show that wind and geothermal powered manufacturing in Kenya can clearly drive continued economic growth in East Africa. When integrated effectively, hydrogen can be part of that strategy.\u201d<\/p>\n
