Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

These gases come from human activities such as combustion of coal and oil as well as natural sources such as emissions from plants. A comparison of regional to global model projections shows that the global model is biased high in surface ozone compared to the regional model and compared to observations. Supercomputing.

NREL: battery second use offsets EV expense, improves grid stability; recommendations

Green Car Congress

In comparison to automotive service, use in this application will entail relatively benign duty cycles, generally much less than one cycle per day with discharge durations of greater than one hour. In addition, degradation and related statistics from automotive service should be quantified and shared.
