CESifo: EVs not the best option for reduction in on-road CO2 in Germany given power mix

Green Car Congress

They report that even with today’s technology, total emissions from a combustion engine powered by natural gas are already almost one-third lower than those of a diesel engine. —Professor Buchal. This being the case, the German federal government should treat all technologies equally and promote hydrogen and methane solutions as well.

Royal Academy of Engineering Report Says EV Success Depends on Low-Carbon Electricity, Universal Broadband Provision and Smart Grids

Green Car Congress

The introduction of electric vehicles on a large scale in the UK can only have a beneficial effect on CO 2 emissions if low-carbon electricity, universal broadband provision and smart grids are in place to support the transition, according to a new report published by the UK Royal Academy of Engineering. Dr Chris Brace, Bath University.

New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

The new flow battery uses only one tank and pump and uses a simple coating instead of an expensive membrane to separate the anode and cathode. The work is some of the earliest supported by the DOE’s new Joint Center for Energy Storage Research battery hub (JCESR). Batteries Power Generation Smart Grid' Click to enlarge.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. We find that annual material resource production places tight limits on Li-ion, VRB and PHS development and loose limits on NaS and CAES.

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. High Wind Future: In this scenario, they modified the future case to add wind plants sufficient to produce 20% of generation.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. C, two-thirds of its maximum discharge capacity is observed.
