Capturing carbon: West Carleton high school grad hopes to use seawater to slow climate crisis

“What’s special about this project is that it takes CO2 out of the ocean, as well as the atmosphere.”

Big changes need big ideas and these can come from anywhere — even the lush farmland of West Carleton (near Ottawa, Canada).

Devinder Sarai is working on one such big idea: his goal is to combat the climate crisis that is threatening our planet.

Sarai’s big idea is called Cequest. In essence, the recent graduate from West Carleton Secondary School wants to build a technology that uses seawater to capture carbon dioxide from the air and ocean; turn it into a mineralized bicarbonate; and sink it back into the oceans where it will be sequestered.

The process has the added benefit of adding alkalinity to the oceans to balance out the acidity that poses a risk to our blue planet. Sarai’s even got a fundraising campaign underway to raise enough money to compete for Elon Musk foundation’s XPrize for Carbon Renewal.

“We’re taking CO2 out of the atmosphere,” he told Capital Current. “What’s special about this project is that it takes CO2 out of the ocean, as well as the atmosphere.”
