'Big sponge': new CO2 tech taps oceans to tackle globalwarming
Scientists from University of California Los Angeles have been working for two years on SeaChange—an ambitious project that could one day boost the amount of COTheir goal is"to use the ocean as a big sponge," according to Gaurav Sant, director of the university's Institute for Carbon Management .sinks, acting as a critical buffer in the climate crisis.emissions, as well as 90 percent of the warming that has occurred in recent decades due to increasing greenhouse gases.
But they are feeling the strain. The ocean is acidifying, and rising temperatures are reducing its absorption capacity. The UCLA team wants to increase that capacity by using an electrochemical process to remove vast quantities of CO"If you can take out the carbon dioxide that is in the oceans, you're essentially renewing their capacity to take additional carbon dioxide from the atmosphere," Sant told AFP.
At the port of Los Angeles, a strange-looking barge covered with pipes and tanks contains a concept that hopes to help tackle global warming.Engineers built a floating mini-factory on a 100-foot long boat which pumps in seawater and subjects it to an electrical charge.dissolved in the seawater into a fine white powder containing calcium carbonate—the compound found in chalk, limestone and oyster or mussel shells.
