In 2015, Shell installed a carbon capture facility at its Scotford refinery northeast of Edmonton in Alberta. According to Dezeen, the system was designed to eliminate emissions from hydrogen production. And lo and behold, Shell is trumpeting the fact that it actually captured close to five million tons of carbon dioxide over the course of 5 years. Great news, right?
No, says Global Witness, which claims the facility actually released more carbon emissions than it captured — 7.5 million tons worth, equivalent to the carbon footprint of 1.2 million cars. The greenhouse gases emitted included highly potent methane, which in the short term has a more than 80-times higher global warming potential than carbon dioxide.
Global Witness argues that this casts doubt on the messaging pushed by the oil and gas industry that carbon capture and storage technology makes it possible for hydrogen derived from natural gas to be used as a “low emissions” fuel to help the world reach its net zero goals. “Fossil fuel companies see fossil hydrogen as a way of continuing to make profits from extracting and burning fossil gas, whilst greenwashing it at the same time,” the report says.
