Startups Are Growing Kelp Farms To Make Biofuel

Challenging regular sources of energy such as solar, wind, and hydropower are some unusual contenders. Thanks to the growing innovativeness of professionals and amateurs alike, it’s possible to harvest energy from walking and even sweating. Now, scientists are harvesting biofuel from kelp forests growing in the Pacific Ocean.

Kelp is transformed into biofuel by a process called thermochemical liquefaction. 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.

Biofuels are sustainable and non-polluting, making them great contenders against fossil fuels. Extracting the product from kelp is low-maintenance and unbelievably fast. Asian countries, in particular, are well-versed in the kelp industry, growing it primarily as a food source. However, this is where American startups may be biting off more than they can chew.

“They already have a pre-existing infrastructure that’s pretty sophisticated for growing and harvesting. It’s harvesting for food and other products… And that’s a much better starting point than small companies in the U.S. that try to go from ground zero to a transportation fuel.”

Nonetheless, open-ocean farming is very much a possibility in terms of biofuel production. With 71% of the planet’s surface water-covered, utilizing oceans for the benefit of the environment isn’t such a bad idea.
