DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

estimated that with conversion by hydrothermal liquefaction (HTL) and upgrading, the wet waste resource availability in the United States could be converted to jet fuel that is equivalent to about 24% of the U.S. Skaggs et al. demand in 2016. 1c06561.

IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

Renewable energy sources are central to the energy transition toward a more sustainable future. However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial.

Bombardier (now Alstom) to convert AGC hybrid trains to full battery power

Green Car Congress

To help France meet its sustainability targets, Bombardier will now convert AGC hybrid trains to full battery power. The idea is to convert dual-mode (catenary and diesel-powered) high capacity self-propelled trains to dual-mode battery-powered AGCs.

Strategic Biofuels successfully tests carbon capture and storage for renewable diesel plant

Green Car Congress

LGF is the first renewable diesel fuel project to achieve this milestone. Carbon capture and permanent geologic sequestration is no longer a hypothetical scenario for Louisiana Green Fuels—successful completion of the test well is a major milestone that’s not been achieved by any other renewable diesel project.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a new method to convert captured CO 2 into methane, the primary component of natural gas. Different methods for converting CO 2 into methane have long been known. A paper on the work is published in ChemSusChem. —Heldebrant et al.

Rolls-Royce mtu Kinetic PowerPack approved for renewable diesel

Green Car Congress

Rolls-Royce has approved its mtu Kinetic PowerPacks, based on the mtu Series 4000 and 1600 diesel engines, for use with renewable diesel (HVO/Hydrogenated Vegetable Oil) and the other synthetic diesel fuels of the EN15940 standard. Part of the energy stored in the flywheel is used to drive the generator that begins producing electrical power.

New electrocatalyst converts CO2 into ethanol, acetone, and n-butanol with high efficiency

Green Car Congress

The electrocatalytic conversion of CO 2 using renewable energy could establish a climate-neutral, artificial carbon cycle. Excess energy produced by photovoltaics and wind energy could be stored through the electrocatalytic production of fuels from CO 2. These could then be burned as needed.
