The startup led by two founders of the travel app Hopper will work with Vancouver-based Svante to research whether it’s possible to capture, transport and store carbon dioxide permanently in the St. Lawrence River Valley in southern Quebec. (The Logic)

Talking point: The ability to do so would help accelerate the rollout of carbon-capture solutions at a large scale, the companies said. Less than a year old, Deep Sky is aiming to build “the world’s first gigaton-scale” carbon-removal company. In July, it partnered with California-based Captura to build a direct-ocean capture pilot facility in eastern Quebec. On Wednesday, it announced it’s partnering with Elon Musk’s XPrize, providing the non-profit that holds contests to stimulate innovation with opportunities to pilot carbon-removal solutions and gain access to licensing deals. Interest in CO2 removal has risen with Squamish, B.C.-based Carbon Engineering announcing a US$1.1-billion acquisition deal earlier this week and Svante netting the biggest venture capital raise by a Canadian company—a US$318-million Series E—last quarter.
