The US Department of Energy has taken an interest in carbon sequestration, but a grand scheme to induce thick blooms of carbon-fixing algae has yet to bear fruit in early studies. The DOE directs a large share of its global warming budget to carbon-sequestration research, drawing on biologists in hopes of enlisting algae, microbes, or plants to fix and store excess carbon created by the fossil-fuel economy. It has awarded tens of millions of dollars in biology-based research grants to geneticists, bioinformaticians, and cell biologists across the country.
