The pair could pilot Amogy’s proprietary ammonia cracking technology to power data centres and semiconductor facilities at Hoku’s projects across the continent.

Amogy’s technology uses catalysts to crack ammonia into hydrogen, which can be fed into fuel cells or engines for power generation.

Under a fresh memorandum of understanding (MOU) Hoku and its energy-focused subsidiary will assess the suitability of trialling the systems at its projects, which include sites in Japan, Taiwan, and Singapore.

Amogy, which has previously been particularly active with its maritime sector applications, secured $79m in venture finance funding in 2025. $23m of this was earmarked for pushing its growth in Asia.

In September, it partnered with Singapore’s R&D agency with an MOU aimed at developing its technology with the country’s data centres as an area of focus.

Ammonia-to-power is emerging as a potential solution for the increasing demand for dispatchable energy driven by power-consuming data centres.

Proponents say it offers a potential route to low-carbon energy with the added benefit of easier storage and transport compared to hydrogen, making it particularly attractive in grid-constrained regions.

However, its multiple conversion steps make for low overall efficiency, and safety, toxicity, and emissions remain potential barriers to its large-scale deployment.
