INCREASING THE OCEAN'S ABSORPTION OF CARBON DIOXIDE
INCREASING THE OCEAN'S ABSORPTION OF CARBON DIOXIDE A Nova Scotia company has received a million-dollar prize from Elon Musk for its plan to increase the ocean’s ability to absorb carbon dioxide — essentially by dosing it with an antacid. Dartmouth-based Planetary Technologies announced Friday it has received the cash infusion from XPRIZE Carbon Removal — a four year, international competition backed by the Elon Musk Foundation with the aim of speeding up climate solutions. Planetary was one of 15 companies to win XPRIZE’s Milestone Award out of an initial pool of more than 1,000. The company’s plan involves treating mine tailings — the debris left behind when mines are dug — to remove toxic substances and any valuable metals, then treating the tailings to produce an alkaline powder. When that powder is distributed into the ocean, it lowers the acidity of the water, thereby increasing its absorption of carbon dioxide. The company projects that by 2035, it c...
