How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Second, conventional coal and nuclear plants are being retired for economic and policy reasons, removing stable sources from the grid. Packetized energy management (PEM) allows the power grid to flexibly handle a varying supply of renewable energy.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. Small Battery: For this scenario, they modified the base case so that the vehicle fleet is based on the Toyota Plug-in Prius.

Study Finds Coordinated Off-peak Charging Can Support Large Scale Plug-in Use Without Additional Generation Capacity; TCO and GHG Abatement Costs for BEVs Projected to Remain High

Green Car Congress

Derive GHG emissions and costs of charging of EVs in the 2015 Dutch context and. from 2015 onwards because higher efficiency of wheel motor drivetrains allows for smaller. They used Li-ion batteries with a cost of €960/kWh in 2010, and assumed this reduces to €800 /kWh around 2015, and to €400/kWh in the more distant future.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In At present, PHEV technology alone is equipped to improve the current electric grid. Appendix E: PHEV and the Electrical Grid—fast charge v.

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.

Geely invests in Carbon Recycling Intl.; vehicles fueled by methanol from CO2, water and renewable energy

Green Car Congress

In late April 2015, Geely Auto deployed a first-of-its-kind fleet of 150 methanol-fueled taxis in the southern Chinese city of Guiyang in cooperation with the municipal government. Methanol can be produced from a range of renewable sources and fossil-fuel based feed-stocks; in practice methanol is mainly produced in coal-rich China from coal.
