Microsoft is doubling down on a controversial plan to capture carbon dioxide emissions from wood-burning power plants. It announced a contract with energy company Stockholm Exergi to capture 3.33 million metric tons of carbon emissions from a biomass power plant in the Swedish capital in what is potentially the biggest deal of its kind to date — equivalent to taking more than 790,000 gas-powered cars off the road for a year.
By doing so, they believe they can achieve negative emissions — taking more CO2 out of the atmosphere than this source of energy produces. Negative emissions technologies like this have become popular with companies trying to offset the environmental impact of their carbon pollution. --- Carbon capture and storage is an umbrella term for a suite of technologies that capture carbon dioxide emissions from industrial sources including power plants, refineries, and factories.
