US firm claims ‘ultra-low carbon’ blue hydrogen process

Known as ⁸RH₂, the technology at the core of the process is a CO2 Convective Reformer (CCR) developed by UK chemical engineer Rodney Allam, one of the pioneers of the Allam-Fetvedt-Cycle (AFC). According to 8 Rivers, ⁸RH₂ builds on the AFC, taking natural gas and combusting it with pure oxygen. The CO2 produced in the combustion process acts as a heat transfer medium, allowing it to be sequestered without the need for amine or cryogenic-based CCS methods. 8 Rivers said this will allow ‘ultra-low carbon’ cost-competitive blue hydrogen production at scale.

“At 8 Rivers, we are dedicated to accelerating the global transition to a sustainable energy landscape,” said Cam Hosie, CEO of 8 Rivers.

“This breakthrough in hydrogen technology is a testament to our commitment to innovation and environmental stewardship. We are excited to collaborate with partners and stakeholders to deploy the ⁸RH₂ technology worldwide and to drive the transition to Net Zero on a global scale.”
