CMU county-level study shows plug-ins have larger or smaller lifecycle GHG than gasoline ICE depending on regional factors

Green Car Congress

A US-wide county-level study comparing lifecycle greenhouse gas (GHG) emissions from several light-duty passenger gasoline and plug-in electric vehicles (PEVs) has found that PEVs can have larger or smaller carbon footprints than gasoline vehicles depending on regional factors and the specific vehicle models being compared.

Baltimore Gas and Electric Company to Launch Plug-in Trial; GridPoints Smart Charging Software to Manage Grid Impacts

Green Car Congress

Baltimore Gas and Electric Company (BGE), a subsidiary of Constellation Energy, has launched a multiyear plug-in hybrid electric vehicle (PHEV) demonstration project using GridPoint’s smart charging software ( earlier post ). BGE will also evaluate the impact a PHEV fleet has on the company’s carbon footprint.

Study Concludes That Smaller Capacity PHEVs Would Be a “Robust” Option for Minimizing Fuel Consumption, Cost and GHG Emissions

Green Car Congress

Best vehicle choice for minimum fuel consumption, cost, or greenhouse gas emissions as a function of distance driven between charges across sensitivity scenarios. When charged frequently (every 20 miles or less), using average US electricity, small capacity (i.e., Shiau et al. 2009) Click to enlarge.

CMU study explores optimizing PHEV design and allocation to minimize life cycle cost, petroleum consumption, and GHG emissions

Green Car Congress

Jeremy Michalek and colleagues found that while a fleet with plug-in hybrid electric vehicles (PHEVs) with universal high electric range (i.e., kW h electricity, $400/kW h Li-ion batteries, $600/kWh NiMH batteries, and 5% discount rate, PHEVs are part of the least-cost solution for gas prices above $2.6/gal,

CMU/Ford study assesses optimal mix of conventional, hybrid, plug-in hybrid and electric vehicles for minimizing GHG and cost

Green Car Congress

In a new study, a team from Carnegie Mellon University (CMU) and Ford Research and Advanced Engineering set out to determine the optimal mix for the fleet of mid-size personal vehicles in the US—while maintaining current driving patterns—with the goals of minimizing greenhouse gas emissions (GHG) or cost. We follow Shiau et al.

Third Phase of SDGE In-Use Study Shows PHEVs Excel on Fuel Economy and GHG Emissions Reductions Compared to Gasoline ICE and Hybrid-Electric Vehicles

Green Car Congress

One of SDG&E’s converted PHEVs. The third phase of a SDG&E multi-year in-use study on plug-in hybrid electric vehicles showed that plug-in hybrids offer significant improvements in gas mileage and reductions in emissions when compared with standard hybrid-electric and gasoline internal combustion engine (ICE) vehicles.
