A green algae liquid sloshes back and forth in culture vats and circulates through shiny bioreactors and bulging plastic tubes. The first tests of algae-based fuels are already being conducted in automobiles, ships and aircraft. Investors like the Rockefeller family and Microsoft founder Bill Gates are betting millions on the power of the green soup. "Commercial production of crude oil from algae is the most obvious and most economical possible way to substitute petroleum," says Jason Pyle of the California-based firm Sapphire Energy, which is already using algae to produce crude oil.
The established oil industry is also getting into the business. "Oils from algae hold significant potential as economically viable, low-emission transportation fuels and could become a critical new energy source," says Emil Jacobs, vice president of research and development at Exxon Mobil. The oil company is investing $600 million (€420 million) in genetic entrepreneur Craig Venter's firm Synthetic Genomics.
The technology holds considerable promise. Indeed, whoever manages to be the first to sell ecologically sustainable and climate-neutral biofuel at competitive prices will not only rake in billions, but will also write history.
