"In February, ExxonMobil gave up its decade-long attempt to cultivate algae as a profitable and scalable feedstock for biofuel — a liquid alternative energy source needed to power aviation, ocean-going ships, and long-distance trucking, while also combating climate change.
That corporate setback was offset by advances elsewhere in the industry: California-based algae biofuel company Viridos, which lost ExxonMobil as its partner, raised $25 million this year as it gained United Airlines, Chevron and Breakthrough Energy Ventures as investors to keep its algae project moving toward commercialization.
Also, this year, the U.S. Department of Energy Bioenergy Technologies Office (BETO) funded four major algae biofuel and biomass projects to chart scalable production processes and achieve low-carbon intensity efficiency.
Several of these algae initiatives are now moving from basic R&D into pilot programs, with scaled-up commercial production possibly just a few years away, according to industry experts. Environmentalists are concerned about future land, energy and fertilizer impacts during production, though say it is too early to assess potential commercialization effects."
