CEMEX is collaborating with UK-based process developer Hiiroc to trial a revolutionary hydrogen production process at its cement plant in Rugby, UK. The process, utilizing plasma technology, aims to provide greener industrial heat production by January 2026. This approach is considered more efficient than water electrolysis, requiring significantly less electricity, and more environmentally friendly than steam methane reforming as it does not produce CO2. Hiiroc's plasma electrolysis process involves splitting hydrocarbons into hydrogen and carbon using electric fields generated by plasma torches. The carbon is then turned into solid carbon black, eliminating sooting that hinders traditional processes. The modular nature of the process allows for easy integration into existing infrastructure, enabling on-demand hydrogen production without the need for extensive transport or storage. The Rugby plant project seeks to optimize the use of hydrogen alongside other fuels to reduce carbon emissions. If successful, the project could lead to a substantial reduction in fuel-related emissions, potentially exceeding 50%. Additionally, the process generates carbon black as a byproduct, which can be utilized in various industries, offering additional revenue opportunities. Beyond the environmental benefits, the Hiiroc process addresses water scarcity concerns compared to water-intensive electrolysis. This innovation has the potential for global expansion within CEMEX operations, aligning with the company's goal of achieving net zero emissions by 2050. The partnership with Siemens for advanced control technology further enhances the process's efficiency and scalability.
