The Allam-Fetvedt Cycle and NET Power
Affordable Energy now means zero-emissions.
8 Rivers has developed the Allam-Fetvedt Cycle, the only technology that will enable the world to meet its climate targets without paying more for electricity. The Allam-Fetvedt Cycle is a new way to generate low-cost power from carbon-based fuels without producing air emissions. It’s also the technology behind NET Power.
Affordable energy now means Zero Emissions. The Allam-Fetvedt Cycle is reinventing emissions capture from its source.
About the project:
The future of our planet – considering a rapidly growing global population – demands a balanced portfolio of renewables and carbon-based methods of power generation, particularly those employing carbon capture. Free emissions capture is the holy grail of carbon-based power generation. Today, power cycles require the addition of expensive, efficiency-reducing equipment to decrease and capture emissions. The Allam-Fetvedt Cycle is a new type of power cycle that takes a novel approach to emissions reduction. It uses the oxy-combustion of carbon fuels and a high-pressure supercritical CO2 working fluid in a highly recuperated cycle that captures all emissions by design. The only by-products are liquid water and a stream of high-purity, pipeline-ready CO2. The cycle can utilize a variety of fuels, including natural gas, unprocessed raw and sour gas, and gasified solid fuels such as coal or biomass. The Allam-Fetvedt Cycle embodies major advantages over conventional systems: attaining high efficiencies at low costs with low to no water consumption. All this with full, free emissions capture.
Problem
In order to meet the world’s carbon targets, we must develop cost-effective technology to eliminate CO2 emissions from carbon-based fuels.
Key Innovation
Using high pressure CO2, instead of steam, as the system working fluid.
Solution
An entirely new power cycle that generates emissions-free electricity from carbon-based fuels for lower costs than traditional, emitting technologies.
Status
The 50MWth Allam-Fetvedt Cycle demonstration facility is currently operating in La Porte, Texas. Several natural gas commercial projects are currently in development. Progress of the coal-based system is also underway.
