Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle.

DOE tool allows consumers to estimate localized upstream greenhouse gas emissions for EVs and PHEVs

Green Car Congress

The US Department of Energy (DOE) has published a Beyond Tailpipe Emissions Calculator that provides estimates of total greenhouse gas (GHG) emissions associated with driving an electric vehicle (EV) or plug-in hybrid electric vehicle (PHEV), including emissions from the production of electricity used to power the vehicle.

The EV Transition Explained: Can the Grid Cope?

Cars That Think

There have been vigorous debates pro and con in the United States and elsewhere over whether electric grids can support EVs at scale. Palo Alto’s government has set a very aggressive Sustainability and Climate Action Plan with a goal of reducing its greenhouse gas emissions to 80 percent below the 1990 level by the year 2030.

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

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. The researchers collected simulated rides provided by three fleets: gasoline-powered, and electric-powered with either 40 kWh or 60 kWh battery packs. Scott Institute for Energy Innovation.
