We also have to capture emissions from plants in hard-to-abate sectors such as steel and cement. The numbers here are perhaps easier to comprehend. The International Energy Agency (IEA) estimates over 1 billion tonnes must be captured every year by 2030 to be in with a chance of meeting net zero by 2050 – requiring a considerable scale up from the 40 million tonnes capacity today. Meeting that target would put a dent in the emissions from 5200 industrial facilities globally that the IEA says are each emitting more than 1 million tonnes of carbon dioxide every year.
With an eye on this, Climeworks is partnering with Canadian CCS specialist Svante. Co-locating its DAC plants alongside CCS power plants could allow Climeworks to use waste heat to produce synthetic fuels from the captured carbon dioxide. It’s also working on a US Department of Energy funded project to combine Svante’s MOF sorbent into its modular systems at a renewables generation site in California.
