![]() But NET Power's system can be air-cooled (with the trade-off being "a small reduction in efficiency," according to the company's press release), and the CO 2 turbine uses no steam. Many coal plants use water to create steam to power turbines, and fossil fuel plants in general often use water to cool the plant's machinery. Power plants can be massive water consumers. With that context, NET Power's plant could be a reasonable transition technology as we move to a low-carbon future.Īnother advantage of NET Power's system is that it can be designed to use very little water. But power companies continue to build fossil fuel plants throughout the US and especially overseas, with no signs of slowing down. And while NET Power's system is zero-emissions, it's also still creating more CO 2-something we decidedly don't need more of. ![]() There are two sides to this technology: on the one hand, a solution like NET Power's doesn't do anything to clean up our existing fleet of fossil fuel plants.
