8 Rivers Hydrogen
Hydrogen that is clean and affordable.
8 Rivers has developed a new process – called 8RH2 – for generating clean hydrogen with full carbon capture that is cheaper than all other hydrogen production technologies today.
8 Rivers is reinventing hydrogen generation to decarbonize the world around us – buildings, industry, transportation, and agriculture.
About the project:
Hydrogen holds the potential to reduce pollution across the economy. It can fuel trucks, heat homes, create high-grade heat for factories, and be a fuel substitute for existing power plants. But to achieve this promise, hydrogen production must itself be clean and affordable. Most hydrogen today is generated by steam methane reforming from natural gas, which is cheap but releases significant amounts of carbon dioxide. 8RH2 solves this problem by reforming with natural gas and pure oxygen, combined with cryogenic CO2 capture. It generates hydrogen at high pressure while capturing CO2 using a proprietary refrigeration based CO2 separation system. This is cheaper and cleaner than traditional steam methane reforming approaches that also release all their carbon dioxide.
Problem
To cut carbon emissions from industry, chemical processes, refining and agriculture we must develop hydrogen generation that’s affordable and clean.
Key Innovation
Using pure oxygen, combined partial oxidation/gas heated reforming, and a novel CO2 capture system to generate clean hydrogen at higher efficiency.
Solution
A better way to make hydrogen from natural gas that has lower emissions, higher efficiency, and superior economics.
Status
Full-scale projects using this combined reforming system are under development today.
Affordable
8RH2 is the same cost or better than conventional methods that do no capture their carbon emissions, and made cheaper still with CO2 sale.
Carbon Capture
By design, the system captures its CO2 for permanent storage underground or use in other industrial processes.
High Efficiency
8RH2 is 75% efficient with 90% carbon capture, and can reach 87% efficiency with 100% carbon capture when integrated with the Allam-Fetvedt Cycle.
Commercially Available
Uses commercially available equipment, making it ready for large-scale deployment today.
