![]() Artificial processes have been devised to produce similar effects, including large-scale, artificial capture and sequestration of industrially produced COĢ using subsurface saline aquifers or aging oil fields. These changes can be accelerated through changes in land use and agricultural practices, such as converting crop land into land for non-crop fast growing plants. Ģ) is naturally captured from the atmosphere through biological, chemical, and physical processes. There are two main types of carbon sequestration: geologic and biologic (also called biosequestration). : 2248 Carbon sequestration is a naturally occurring process but it can also be enhanced or achieved with technology, for example within carbon capture and storage projects. Ĭarbon sequestration (or carbon storage) is the process of storing carbon in a carbon pool. "It's very simple, and the economies of scale associated with that make Running Tide's solution have huge potential.Schematic showing both geologic and biologic carbon sequestration of the excess carbon dioxide in the atmosphere emitted by human activities. "They're not relying on expensive equipment, or energy-intensive processes," she says. She says Shopify is willing to pay a premium for the credits now, in hopes the technology can ultimately be brought to a price-point that would attract broad buy-in from other businesses and governments. "When we started learning about Running Tide's approach, I was blown away by the simplicity," says Stacy Kauk, who directs sustainability efforts at Shopify, a $150-billion e-commerce company which will be Running Tide's first customer for carbon-capture credits. But Running Tide seems to be capturing attention - and investment - because of its low-tech elegance. Pumps injecting plant-based biofuels into the earth. Towering banks of fans that can pull CO2 from the sky. High-tech carbon-removal innovations are emerging around the world. It also promised to find ways to remove all the CO2 its operations have put in the air since it was founded. Microsoft last year committed a billion dollars to kick-start research and development in the emerging field of carbon-removal tech. ![]() The company is part of a new wave of big-thinking about removing carbon from the atmosphere at a planetary-scale. Investigations As Cities Grapple With Climate Change, Gas Utilities Fight To Stay In Business ![]() But he watched as the warming climate drove major shifts in fish populations, while regulators put a lid on how much could be taken from the sea. Running Tide CEO Marty Odlin - the boat captain's nephew - comes from a long line of Maine fishermen, and once imagined he would continue the tradition. "We're just fishing for carbon now, and kelp's the net," he says. On a recent day in the Gulf of Maine, boat captain Rob Odlin says the task itself isn't much different from any other in his seafaring career, whether chasing tuna or harvesting lobster. The company is called Running Tide Technologies, and it's prototyping the concept this winter. One startup in Maine has a vision that is drawing attention from scientists and venture capitalists alike: to bury massive amounts of seaweed at the bottom of the ocean, where it will lock away carbon for thousands of years. In the race to stall or even reverse global warming, new efforts are in the works to pull carbon dioxide out of the air and put it somewhere safe. They release rope that's entwined with early-stage kelp, a fast growing seaweed that will soak up carbon dioxide. Rob Odlin of Running Tide Technologies in the Gulf of Maine.
