8 Rivers has announced a groundbreaking advancement in hydrogen technology that will revolutionise the production of ultra-low carbon hydrogen and ammonia, the 8RH2 technology.

8RH2 harnesses advanced CO2 processes in a CO2 Convective Reformer (CCR), including some of the same processes pioneered in the AFC, building on decades of decarbonisation expertise developed by 8 Rivers.

The 8RH2 technology has been invented by Rodney Allam MBE, a chemical engineer from Bath in the UK, who also pioneered the Allam-Fetvedt-Cycle (AFC) cycle, the first new power cycle since World War II.

With 8RH2's ability to capture greater than 99 per cent of carbon emissions at a cost and scale currently unrivaled in the market, Allam's hydrogen innovation promises to redefine what is possible for global decarbonisation.

The 8RH2 oxy-combustion process can eliminate virtually all direct CO2 emissions. It uses natural gas and pure oxygen and then utilises the CO2 produced in the combustion process as a heat transfer medium in a proprietary reformer before sequestering the CO2.

In addition, 8RH2‘s advanced process eliminates the need for costly amine or cryogenic-based CO2 separation processes that are normally required to capture CO2, as carbon separation is inherent to the process itself.

The ultra-low carbon hydrogen then can be turned into ultra-low carbon ammonia, which in turn can be used for decarbonised fertiliser, zero-carbon maritime fuels, and as a zero-carbon feedstock fuel to replace coal in existing power infrastructure.

Ammonia is easily stored in bulk at modest pressures, has an existing global distribution network and is easier to transport than hydrogen. Ammonia can be easily ‘cracked’ back into hydrogen after reaching its end user. 8RH2-produced ammonia will provide a transportable low-carbon source of hydrogen, a low-cost and scalable solution to accelerate the global transition to net-zero.

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