U Delaware team develops prototype efficient direct ammonia fuel cell for transportation

Green Car Congress

A team at the University of Delaware has demonstrated a direct ammonia fuel cell (DAFC) prototype with a peak power density of 135 mW cm -2 at 80 ?C. Carbon-neutral fuels are needed for sustainable transportation to overcome the range and recharge limitations of batteries and the scale limitations of biofuels. Zhao et al. Zhao et al.

New highly selective and efficient catalyst for reduction of CO2 to CO

Green Car Congress

Researchers at the University of Delaware have developed a highly selective nanoporous silver catalyst capable of electrochemically reducing carbon dioxide to carbon monoxide with 92% efficiency. The carbon monoxide then can be used to produce synthetic fuels and chemicals. Qi Lu, Jonathan Rosen, Yang Zhou, Gregory S.

Mitsubishi Motors, NewMotion, Nuvve in vehicle-to-grid pilot in Netherlands with Outlander PHEV

Green Car Congress

University of Delaware Professor Willett Kempton, the pioneer of the grid-integrated vehicle concept, is Nuvve’s CTO.). As solar, wind and other renewable sources, which are intermittent, replace fossil fuels as a source of energy and enter mainstream power grids, stabilizing the power supply also poses a challenge.

OnStar and Google demonstrate concept service for managing charging Chevrolet Volts with renewable energy

Green Car Congress

Wind accounted for 2.3%. PJM data shows that peak time for renewable energy generation from wind is generally between 10 p.m. With this in mind, it would be possible for customers to use OnStar’s Smart Grid solutions to further reduce their carbon footprint and save money by charging during these off-peak times.

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.

Study: new international agreements needed to ensure sustainable supply of minerals and metals for low-carbon energy tech

Green Car Congress

A study by an international team of researchers warns that the global transition to global low-carbon energy technology could be at risk unless new international agreements and governance mechanisms are put in place to ensure a sustainable supply of rare minerals and metals. Their paper is published in Science. —Sovacool et al.
