Iceland and Canada lie over 4,500 kilometres apart on a world map, yet news that a pioneering carbon removal project near Reykjavik is falling well short of expectations a year after its launch has hit home with some North American sector skeptics closely watching the climate technology’s progress. Switzerland’s Climeworks, which has raised US $800 million, opened the world’s largest operational direct air capture (DAC) plant, known as Mammoth. But the facility, which uses what look like walls of giant fans to capture CO2 directly from the air and then pumps it deep underground, has not measured up to expectations. …The slow start has sparked discussion in clean energy circles over the wisdom. …Prime Minister Mark Carney said Canada could be a leader in carbon capture and storage as part of a controversial effort to decarbonize oil and gas, including extending tax credits and setting carbon dioxide removal targets.
