​Bid to cut carbon-capture cost 80% gets nudge in joint venture

Source: Climeworks

Two companies that come at carbon capture differently will be working together with a goal to lower the cost of the technology by about 80 per cent, making it more widely accessible in the fight against climate change.

Canada-based Svante Inc. will provide Climeworks, a Zurich-based pioneer in direct-air-capture, access to its patented solid absorbent technology, the companies said in a statement. They plan to develop facilities that simultaneously capture the greenhouse gas from both industrial sources and ambient air.

The goal for Climeworks: Cut costs for capturing CO2 from ambient air to about $100 a ton from around $600 now. High costs and the lack of a market has largely meant that carbon capture technology is only economically viable for multibillion-dollar facilities connected to large, industrial emitters.

Combining the companies’ systems will “create a game changer in the industry to be able to do direct-air capture at a smaller-sized plant,” Svante Chief Executive Officer Claude Letourneau said in an interview.

A dramatic expansion of carbon-capturing technologies will be necessary for limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit), according to last year’s report from the United Nations Intergovernmental Panel on Climate Change.

Climeworks introduced a commercial-scale, direct-air capture plant in 2017, which it says was the world’s first such facility. The plant in Hinwil, Switzerland, near the company’s headquarters in Zurich, looks like a scaffold studded with 18 jet engines, and filters 900 tons of C02 out of the air a year.

Solid Nanomaterials

Svante’s technology uses solid nanomaterials that have a high storage capacity and can catch and release CO2 within a minute’s time, compared with hours for other technologies, according to the statement. The company is designing its systems to be modular, easily scalable and to require relatively little custom adaptation.

Based in Burnaby, British Columbia, Svante has a plant online that captures 30 tons of CO2 a day at a Husky Energy Inc. facility in Saskatchewan, as well as a one-ton-per-day plant at a LafargeHolcim Ltd. facility in Richmond, British Columbia, and a test unit at a Total research facility in France.

Inside the Husky facility, pipes carry flue gas through a large rotating disk packed with the company’s filters. The gas is then hit with low-pressure steam that releases the CO2 into another pipe that carries it away to storage.

The company counts Husky, Mitsui Global Investment, Chevron Technology Ventures, Roda Group, Chrysalix, OGCI Climate Investments and BDC among its investment group, and its board includes former Obama administration energy secretary Steven Chu.
