A more accurate headline for the article would be "Shell's demonstration facility for CCS captures less than half of carbon emissions from Alberta refining operation". Well, duh! It's a technology demonstration. From all indications, it's doing exactly what it was designed to do. But where's the story in that?

Hard to know from the article exactly what is being promised, and what is being delivered. But it appears that process of sequestration itself is emitting more carbon than is being sequestered, and Shell is selling it as a "negative-carbon" technology. If so, the company is either mistaken or lying.

From what I've read about the Quest facility, the CCS pilot part is working to spec. It was never intended to be a full-scale CCS facility for the entire refinery.

"It was never intended to be a full-scale CCS facility for the entire refinery."

It was intended to capture all of the carbon from the hydrogen plant, and it isn't even coming close:

"To put that in perspective, the 'climate-forward' part of the Scotford plant alone has the same carbon footprint per year as 1.2 million fuel-powered cars, Global Witness said."
