Pilot Project Sends Kelp–and Carbon–to the Seafloor

Cars That Think

Last January, in the waters off Cebu City in the Philippines, researchers first deployed a huge flexible ring seeded with seaweed and spanned by spokelike ropes and tubes. Every nightfall, cranks mounted on a floating platform lower the ring 25 meters below the surface to expose the seaweed to cooler, more nutrient-rich water.

Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Now, a study by researchers at the US Department of Energy (DOE) Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has found that energy sorghum ( Sorghum bicolor ) behaves more like miscanthus in the way it efficiently captures light and uses water to produce abundant biomass. Energy sorghum falls somewhere in between.

Purdue and Duke Energy to explore potential for SMR nuclear power source for campus

Green Car Congress

With interest rising worldwide in new technologies that are reliable and carbon-free, Purdue and Duke Energy intend to study power produced through Small Modular Reactors (SMRs), a move that may be unprecedented for a college campus and a potential fit for Purdue’s energy needs. —Purdue President Mitch Daniels.

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. In conventional CTL approaches, energy is supplied by burning a portion of the coal feed, which then produces carbon dioxide. Bottom: SRI process.

Canada backs demonstration-scale algal biorefinery project in the oil sands; Algal Carbon Conversion

Green Car Congress

The Government of Canada is supporting a three-year project that will result in the construction of a $19-million, demonstration-scale facility in Alberta that will use algae to recycle industrial carbon dioxide emissions from an oil sands facility into commercial products such as biofuels.

Study finds removing corn residue for biofuel production can decrease soil organic carbon and increase CO2 emissions; may miss mandated 60% GHG reduction

Green Car Congress

Using corn crop residue to make ethanol and other biofuels reduces soil carbon and under some conditions can generate more greenhouse gases than gasoline, according to a major, multi-year study by a University of Nebraska-Lincoln team of researchers published in the journal Nature Climate Change. Error bars are ± one standard deviation.

Study finds Antarctic icebergs play a previously unknown role in global carbon cycle, climate

Green Car Congress

In a finding that has global implications for climate research, scientists have discovered that when icebergs cool and dilute the seas through which they pass for days, they also raise chlorophyll levels in the water that may in turn increase carbon dioxide absorption in the Southern Ocean.
