This doesn't seem to me that it's "no-emission" it reads more that it the co2 is captured at the source. As a lay person I would assume "no-emission" means no co2, but maybe I'm wrong here?
- waterheater 3y agoNot quite. According to the EPA [1], "Emissions is the term used to describe the gases and particles which are put into the air or emitted by various sources." That includes anything, not only CO2. For example, while CO2 is a common emission from fuel-based power plants, these plants (in particular, coal) may also emit other molecules such as mercury, which is more dangerous to human health than CO2. These all fall under the umbrella of emissions. Even a hydrogen-fueled car has an emission of water, or a "waste product" [2]. And that's the key to understanding it: waste product, which is really what the term emission means. What I talked about has virtually no waste product and therefore no emissions, though perhaps "no emissions" is too optimistic. The NET Power website says "NET Power’s patented technology captures over 97% of CO2 emissions from power generation", so it's darn good but not "no emission".

- pfdietz 3y agoIf I understand correctly, the Allam cycle is can be operated such that it produces net liquid water.
- waterheater 3y agoAs far as I'm aware, that's true. In relation to the previous comments, the water will be classified as a byproduct, not an emission.
