The 8RH2 commercial facility produces clean hydrogen with 99% CO2 capture. Our first project aims to convert the produced hydrogen into ultra-low-carbon ammonia that will be exported to Asian markets.

Description of Technology:

8RH2 harnesses advanced CO2 processes in a CO2 Convective Reformer (CCR), including some of the same processes pioneered in the Allam-Fedvedt Cycle (AFC), building on decades of decarbonization expertise developed by 8 Rivers. The AFC is a proven and proprietary oxy-fired combustion process where fuel is combusted with pure oxygen to produce hot, high pressure CO2. While the 8RH2 reformation process leverages much of the same equipment and process flow of established hydrogen production processes, the CCR enables this pure stream of high pressure and high temperature CO2 to deliver the heat to the reformation reaction. The result is two separate flow streams of CO2 and syngas, similar to SMR, but at high pressures, similar to ATR. However, unlike either of the existing processes, 8RH2’s use of CO2 as the working fluid enables inherent capture of pipeline-ready CO2 without post-combustion carbon capture – saving cost and energy consumption while increasing capture. The hot syngas is then further refined via oxygen secondary reforming to achieve greater efficiencies than traditional hydrogen production processes. Furthermore, the CCR is a prefabricated, compact tube-in-tube (bayonet) design with catalyst filled in an annular space and the product stream exiting from a central tube. This enables the hydrogen production process to operate more efficiently by exchanging heat between the product gas stream and the reforming gas stream. Additionally, as the CCR tubes are not exposed to direct flame, they can be packed in a much tighter configuration. This design allows the CCR to have a smaller footprint and to be prefabricated for faster and cheaper installation.
