GH Power highlights new energy process from aluminium scrap.

Canadian based GH Power uses metals to create green power and hydrogen and has announced a project using aluminium scrap to produce alumina and fuel-cell grade hydrogen. The company has just been selected by PMI Energy to be the technology provider to potentially supply 30MW for Prometheus 1, an AI driven Super Calculator located 200km from Paris, France. A full financial investment decision will be made by Q4 2025.

The capex for the operation will be US$100M, and will be provided by government support, private equity and a global energy company.  Initially planned to provide 30MW, the plant will have room to scale up to 60MW of energy for the data centre. The technology will use 10kt of lower grade scrap aluminium to produce 20kt of alumina, 1,250t hydrogen gas and 3,000KWh/h of steam.

The alumina produced will be 90-99% Al2O3, and in the gibbsite or boehmite forms. The reactor controls can be adjusted to produce a surface area of less than 1m2/g to 400m2/g and in sizes from -40 mesh to submicron. This opens up a number of markets for the alumina including refractory and ceramic applications, replacing traditional calcined, tabular or white fused aluminas.
