First Supercritical CO2 Circuit Breaker Debuts

Cars That Think

The first-of-its-kind device could replace conventional high-voltage breakers, which use the potent greenhouse gas sulfur hexafluoride, or SF 6. Such equipment is scattered widely throughout power grids as a way to stop the flow of electrical current in an emergency. GE Vernova On top of that, SF 6 byproducts are toxic to humans.

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.

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.

Phillips 66 receives $3M grant to advance reversible solid oxide fuel cell technology

Green Car Congress

Phillips 66 will collaborate with the Georgia Institute of Technology (Georgia Tech) to demonstrate the commercial feasibility of a low-cost and highly efficient RSOFC system for hydrogen and electricity generation. In the latter, electricity is applied to the cells to produce hydrogen, a low-emission fuel, through electrolysis.

Georgia Tech study suggests unlinking EVs from CAFE and coordinating with power sector for low-cost benefits

Green Car Congress

For the study, they define EVs as including both battery-electric (BEV) and plug-in hybrid electric (PHEV) vehicles. Only in the case of high EV market share and a high renewable electricity standard (RES) do EVs make a material contribution to greenhouse gas (GHG) reductions, they found. Credit: ACS, Choi et al.
