The technology has not been shown to be worthwhile in the long term. These emissions come from oil and gas. The important thing to remember is that this covers only 20% of the oil sector's emissions. Only production emissions are captured. Even if the technology were perfect—which is far from being the case—we are talking about just 20% of the emissions that cause climate change. The other 80% is emitted when oil is burned in Canada or elsewhere. The lion's share of Canadian oil is burned outside the country.
We have alternatives: electric vehicles and renewable energy such as batteries. That is the path we should be taking. Carbon capture and storage might be significant for the steel industry, maybe. It might be significant for other industries, but we have zero-emission alternatives to oil and gas.
