The first reaction is always the same: It’s too good to be true.
The disbelief is directed at a next-generation power plant under development in Durham by NET Power. Its backers say their machine won’t emit a particle of pollution.
The emissions-free concept exists only on paper today, but a key mechanical component is getting readied for testing in about four months. It would have to elevate the pressure at which natural gas is burned by a factor of several times, a thermodynamic feat that has only been achieved in the aerospace industry but is limited to computer simulations in power plants.
