Statkraft to install GE Rotating Stabilizers in grid-stabilization project in Scotland

Green Car Congress

Statkraft, Europe’s largest generator of renewable energy, has agreed to a deal to help further decarbonize the UK’s power sector and deliver a new approach to managing the stability of the grid. GE Power Conversion will manufacture and install two Rotating Stabilizer synchronous machines at Statkraft’s site in Keith, Moray.

Updated NETL study provides more detailed economic and environmental assessment of coal-to-liquids and CTL with modest biomass

Green Car Congress

The National Energy Technology Laboratory (NETL) has released a follow-on study to its 2009 evaluation of the economic and environmental performance of Coal-to-Liquids (CTL) and CTL with modest amounts of biomass mixed in (15% by weight) for the production of zero-sulfure diesel fuel. Earlier post.). —White and Gray.

Benchmark: hard-rock lithium can be 3x as carbon intensive as lithium from brine

Green Car Congress

The carbon intensity of the electricity grids where the raw material is mined and concentrated and where the lithium chemical is produced strongly impacts the overall carbon intensity of the process. Both the Australian and the Chinese electricity grids are highly dependent on fossil fuels with a large amount of coal power.

Lifecycle analysis finds Fischer-Tropsch diesel from coal and biomass with CCS can use less fossil energy than petroleum diesel, with GHG close to or below zero

Green Car Congress

A new study by Michael Wang and Jeongwoo Han at Argonne National Laboratory and Xiaomin Xie at Shanghai Jiao Tong University assesses the effects of carbon capture and storage (CCS) technology and cellulosic biomass and coal co-feeding in Fischer-Tropsch (FT) plants on energy use and greenhouse gas (GHG) emissions of FT diesel (FTD).

National Research Council Report on Americas Energy Future Highlights Vehicle Efficiency Technologies, Conversion of Biomass and Coal-to-Liquids Fuels, and Electrifying the Light Duty Fleet with PHEVs, BEVs and FCVs

Green Car Congress

Developing technologies for the conversion of biomass and coal-to-liquid fuels. By 2035, cellulosic ethanol and/or coal-and-biomass-to-liquid (CBTL) fuels with carbon capture and storage could replace about 15% of current fuel consumption in the transportation sector (1.7–2.5 emissions, according to the report.

Study Suggests That Optimal Use of Bioenergy as Fuel or Electricity Depends on Market and Regulatory Policy Contexts; Higher-Level Assumptions Can Constrain Questions and Affect Results

Green Car Congress

conversion to fuel molecules or to electrons—depends on market and regulatory contexts that are outside the scope of attributional life cycle assessments (LCA). Electricity from all sources flows into the grid and is used to meet instantaneous system-wide demand. A 2009 life cycle analysis by Campbell et al. Earlier post.)

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

Because the use of natural gas for transportation requires compressing, liquefying, or conversion, it is important to determine the best use of natural gas as a transportation fuel. They assessed scenarios for 25% (RPS-25) and 50% (RPS-50) renewable portfolio standards for EV use along with the current US mix, natural gas, and coal.
