NET Power has delivered electricity on to the ERCOT grid from its 50 MWth test facility in La Porte, Texas. The clean energy company, whose technology generates zero-emission electricity from natural gas, claims it is the first time anywhere in the world this has been achieved, representing a major milestone for the energy industry.
NET Power’s technology burns natural gas and uses supercritical carbon dioxide (CO2) to generate electricity while capturing CO2 and claims the latest ‘is expected to accelerate the commercialisation of this game-changing technology’.
“This is a Wright-brothers-first-flight kind of breakthrough for energy – zero-emission, low-cost electricity delivered to the grid from natural gas-fuelled technology,” said NET Power CEO Ron DeGregorio.
“Now we can expand on our deep bench of partners to accelerate development of commercial NET Power projects around the world that are urgently needed to help achieve aggressive climate targets at an affordable price.”
NET Power is working with multiple clients worldwide to develop utility-scale NET Power plants, with initial projects aiming to come online in the next five years. All CO2 captured by commercial NET Power plants will be permanently stored or utilised. NET Power projects have been publicly announced in the US, Canada, and the UK.
NET Power’s technology combusts natural gas with oxygen, instead of air, and uses supercritical carbon dioxide as a working fluid to drive a turbine instead of steam. NET Power does not produce any nitrogen oxides, sulphur oxides or particulate pollution, and the remaining CO2 is pipeline-quality to either be safely stored in underground geologic formations or utilised for industrial processes. NET Power produces only electricity, liquid water, and pipeline-ready CO2, while operating at high-efficiency, comparable to conventional power plants.
