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.
