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.
Several common problems can cause air conditioner freeze-ups: 1  Insufficient Air Flow: Anything that restricts air flow will cause the temperature of the systemâs evaporator coil to drop below freezing. Humidity in the air will collect on the coil causing ice to build-up and diminish the systemâs cooling capacity.
