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.
Throughout the United States, when air pollution is high, we have Air Now Action Days. These forecast high air pollution days with unhealthy air. During Action Days, people with asthma should limit their time outdoors; especially from 11 a.m. to 8 p.m. Stay in a well-ventilated, preferably air-conditioned, building.
