Methanol economy advantages compared to a hydrogen economy: 1  Efficient energy storage by volume, as compared with compressed hydrogen. 2  A liquid hydrogen infrastructure would be prohibitively expensive. 3  Can be blended with gasoline (for example in M85, a mixture containing 85% methanol and 15% gasoline). 4  User friendly.
Two things contribute to air pollution that can cause an air quality alert: 1  Ground-Level Ozone â High-levels of ground-level ozone are frequently the cause of air quality alerts. 2  Particulate Matter â Particulate matter consists of pollutants such as dust, soot, ash and wood smoke.
The Arizona Department of Environmental Quality (ADEQ) is extending the weekend ozone High Pollution Advisory (HPA) for Maricopa County through Wednesday, August 17, 2016. These HPAs are due to ozone levels expected to accumulate enough to exceed the new, lower federal health standard for ozone.
