Marine algae get the green light from Shell

Shell is to become the first major oil company to produce diesel fuel from marine algae.

Algae are a climate-friendly way to make fuel from carbon dioxide. They produce an oil that can readily be converted to diesel, and can be fed CO₂ directly from smokestacks. Unlike biofuels such as corn, they don't use up soil or water that could otherwise be used to grow food, which can pump up food prices.
