ARPA-E awarding $9.4M to 4 projects focused on removing sulfur hexafluoride from US grid

Green Car Congress

SF 6 has been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 is also an extremely potent greenhouse gas with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere. Georgia Tech in Atlanta, Ga.;

Georgia Tech study finds link between sulfate, metallic particles from vehicles and adverse health impacts

Green Car Congress

Now, researchers at Georgia Institute of Technology have shown how these vehicle-emitted metals—such as copper, iron and manganese—interact with acidic sulfate-rich particles already in the air to produce an aerosol that, when inhaled, is more likely to cause oxidative stress and impact respiratory health.

Georgia Tech team develops simple, low-cost process for oxide nanowires; superior separators for Li-ion batteries

Green Car Congress

Researchers at Georgia Tech have developed a simple technique for producing oxide nanowires directly from bulk materials under ambient conditions without the use of catalysts or any external stimuli. The alloy is then placed in a suitable solvent, which could include a range of alcohols, such as ethanol.

Georgia Tech study finds MD electric urban delivery trucks have cost advantages over diesel in some conditions; relative benefits depend on numerous factors

Green Car Congress

The study found that TCO for electric and diesel medium-duty urban delivery trucks were similar. The electric truck is relatively more cost-effective on the NYCC and when VKT demand is higher. Cost-competitiveness of the electric truck diminishes in drive cycles with higher average speeds. Credit: ACS, Lee et al.

Georgia Tech life-cycle study finds TCO of medium-duty electric and diesel delivery trucks similar; electric life-cycle energy use and GHG lower than diesel

Green Car Congress

They also found that the total costs of ownership (TCO) of the electric and diesel trucks are similar. Over an array of possible conditions, the median TCO of electric trucks is 22% less than that of diesel trucks on the NYCC. However, the cost-competitiveness of the electric truck diminishes in drive cycles with higher average speed.

Anaheim Transportation Network orders 40 BYD electric buses; 57% electric fleet by 2020

Green Car Congress

The Anaheim Transportation Network has awarded an order for 40 battery-electric buses to BYD. The ATN fleet order will increase the number of BYD electric buses the agency can deploy to serve one of the nation’s busiest tourism and employment regions. The buses range in size from the 30-foot BYD K7M to the articulated 60-foot K11M.
