DOE report highlights opportunities of hybrid energy systems

Green Car Congress

As defined for the report, HES are related to, but distinct from, colocated resources, which share some characteristics with HES but have more limited opportunities for operational synergies. Hybridization can also help mitigate financial penalties for variable resources (e.g., Dimensions that define HES. Source: DOE.

PNNL/INL team assesses costs and GHG LCA for converting biomass to drop-in fuels via fast pyrolysis and upgrading

Green Car Congress

A team from Pacific Northwest National Laboratory (PNNL) and Idaho National Laboratory has evaluated the process economics and greenhouse gas (GHG) emissions for the conversion of 11 biomass feedstocks to produce transportation fuels via fast pyrolysis and then pyrolysis oil upgrading via hydrodeoxygenation.

Converting glycerol from biodiesel production into bio-gasoline

Green Car Congress

A team at the University of Idaho has demonstrated that glycerol, a byproduct from biodiesel production, could be used as a substrate for producing drop-in gasoline-range biofuel. Nevertheless, very little research into the direct conversion of glycerol to gasoline-range hydrocarbons has been reported. Tropsch synthesis (FTS).

Sandia progressing to demo stage with supercritical CO2 Brayton-cycle turbines; up to 50% increase in efficiency of thermal-to-electric conversion

Green Car Congress

A number of DOE labs, including Idaho National and Argonne National, have contributed to the body of work. This configuration uses gas-foil bearings and includes a small turbine (red). Resources. The S-CO 2 system is also very compact, meaning that capital costs would be relatively low. Source: Wright et al. Click to enlarge.

DOE finalizes $96.8M loan guarantee for Oregon Geothermal Project; supercritical binary geothermal cycle

Green Car Congress

The technology is estimated to be more efficient than traditional geothermal binary systems, allowing lower-temperature geothermal resources to be used for power generation. Unlike coal-fired and natural gas-fired power generation plants, geothermal plants produce virtually no greenhouse gas emissions. Bliem and G.L.

Co-Electrolysis of CO2 and H2O for the Production of Liquid Fuels

Green Car Congress

Researchers at Columbia University’s Lenfest Center for Sustainable Energy, in collaboration with Risø National Laboratory for Sustainable Energy, DTU, are investigating the high-temperature co-electrolysis of CO 2 and H 2 O using solid oxide electrolysis cells (SOECs) to produce a syngas for conversion into liquid hydrocarbon fuels.
