Alberta has switched on what is billed as the world's first commercial natural gas power plant with carbon capture, trapping about 90% of its turbine emissions and burying them two kilometers underground. The article breaks down the two main methods: point-source capture using amine solvents at the chimney, and direct air capture, which is far more expensive because CO2 is only 0.04% of ambient air. It also covers where the captured CO2 goes, into porous rock where it eventually mineralizes, and the debate over whether the energy and cost of capture undermines its climate benefit. For anyone tracking carbon removal or point-source abatement, this is a useful primer on the technical basics and the policy fight. The piece notes critics who see capture as a subsidy for continued fossil fuel use, while supporters argue it is the only option for cement, steel, and fertilizer plants where emissions are chemical, not just fuel-related. The real question, as the article says, is whether the price is justified. That is the core discussion for carbon markets and project finance.
