Seaweed doesn’t need cropland to grow or need fertilizer and it has a higher oil content most land-grown biofuel sources.
Algae also has a high oil content. A “commercial-scale algae facility” is planned for Maui that will grow algae for biodiesel using co2 emissions from a power plant. Wow.
Given the inevitability of such biofuel sources and the ingenuity of capitalism in, well, capitalizing on new ideas, can algae and seaweed speculation and trading be long in coming? Move over pork belly futures, you’re being supplanted by trading in pond scum.
