Electrolyser contract signed for green ammonia project

Chinese companies Sungrow Hydrogen and CRRC Zhuzhou say that they have secured electrolyser supply contracts for the first phase of a geothermal-powered hydrogen and ammonia project in Olkaria, Kenya, developed by Chinese firm Kaishan Group. Kaishan signed a steam supply agreement with state utility KenGen in October 2025, under which KenGen will supply steam from existing geothermal wells for Kaishan to generate 165MW of electricity to power the electrolysers. Chinese firm Wuhuan Engineering is serving as engineering, procurement and construction contractor. Works on the site began in November 2025.

Sungrow will supply 16 alkaline electrolysers rated at 1,000 Nm³/h each, while CRRC will provide eight units of the same rating, for a total capacity of 24,000 Nm³/h, or around 120MW. This is sufficient to produce roughly 19,000 t/a of hydrogen assuming continuous operation, which will be converted to the 100,000 t/a of ammonia planned for Phase 1. Kaishan plans to increase output to 200,000 t/a of ammonia in a second phase of development, with the ammonia being converted into downstream fertilizers including 180,000 t/a of urea and 300,000 t/a of calcium ammonium nitrate.
