Alberta has switched on what's billed as the world's first commercial natural gas power plant with carbon capture. The plant traps about 90% of CO2 from its turbine and injects it two kilometers underground. This article breaks down the science: amine scrubbing soaks up CO2 like a sponge, then releases it for compression and storage in porous rock where it eventually turns to stone. The piece also explains the difference between point-source capture and direct air capture, which is far more expensive. The core debate is whether the energy penalty and cost are worth it. Critics see it as a subsidy for oil firms, while supporters argue it's the only way to clean cement, steel, and fertilizer production. Both sides have a point, and the article leaves the question open.
