California’s push for renewable energy is nothing new. From solar panel installations to powerful wind turbines in the desert, we’re looking outside of fossil fuels to power our homes and businesses. Now scientists are looking to the sea for the next alternative energy source, right off the coast of Catalina.
The Pacific Coast is known for its vast kelp forests and a recent story on NPR highlighted recent efforts to cultivate that fast-growing plant into biofuel through a process called thermochemical liquefaction.
According to NPR, “The kelp is dried out, and the salt is washed away. Then it’s turned into bio-oil through a high-temperature, high-pressure conversion process.
“Some small companies are growing kelp as a substitute for kale in the U.S., but that’s exactly the problem—very, very few are doing it. Thus, the infrastructure and investment isn’t in place to make other products from kelp, like biofuel.
“’We’re testing out a concept that would enable large-scale, open-ocean farming,” says Diane Kim, one of the scientists running the kelp research project at the University of Southern California. “And what that would essentially do is grow enough kelp to make it economically feasible to make it cost competitive and maybe one day, provide a source of clean, sustainable, non-polluting source of energy to compete with fossil fuels.”
