An actual recreation altering technology demonstrated as we sit in our air-conditioned abodes studying this. And it’s being shown by North Carolina–based Net Power at a new plant in La Porte, Texas.
The process includes burning fossil fuel with oxygen as an alternative of air to generate electricity without, emitting any carbon dioxide (CO2). Not utilizing air additionally avoids producing NOx, the primary atmospheric and health contaminant emitted from gas plants.
Included in a group of applied sciences generally known as carbon seize and sequestration (CCS), zero-emission fossil fuel plants have been a dream by no means realized in following, because it always seems to cost a lot, including between 5¢ and 10¢ per kWh. That is probably as a result of most attempts add on one other step after the standard electricity technology steps, almost as an afterthought.
Some fossil fuel plants have attempted and failed, the most well-known one newly being the $7.5 billion coal power plant under Kemper, Mississippi.
However, this new know-how utterly changes the steps and the strategy from the bottom up. It’s primarily based on the Allam-Fetvedt Cycle, Allam Cycle for brief. That is a brand new, excessive-strain, oxy-fuel, supercritical CO2 cycle that generates low-price electricity from fossil fuels whereas producing close to-zero air emissions.
All CO2 that’s generated by the cycle is produced as an excessive-stress, pipeline-prepared by-product to be used in enhanced oil recovery and industrial processes, or that may be sequestered underground in tight geologic formations the place it is not going to get out to the atmosphere for millions of years.
The Allam Cycle additionally means the facility plant is a lot smaller and will be sited in additional areas than older crops can. If the plant in La Porte performs as anticipated, and because it has thus far, it is an actual recreation changer for natural gas. Since the US is sitting on extra natural gas than any nation on this planet, and it’s getting cheaper to get it out of the ground, that is no small sport to vary.
