Fuel cells offer several advantages: they do not have moving parts and there is no burning involved, so there are negligible emissions of environmentally harmful gases like nitrogen, sulfur oxide and carbon monoxide.
Ertel was soon a big producer at Natsource, trading sulfur dioxide, nitrogen oxide, carbon and even weather derivatives.
The Indiana-based utility is investing in the required equipment to reduce its sulfur dioxide, nitrogen oxide and mercury pollution.
It also releases double the other pollutants regulated by the Clean Air Act that include sulfur dioxide and nitrogen oxide.
The process that smokestack "scrubbers" use to reduce nitrogen oxide and sulfur dioxide emissions creates high-quality synthetic gypsum, said Robert E.
According to EPA, the levels of sulfur dioxide and nitrogen oxide would have been cut in half under the cross-state rule.
FORBES: Winning the Presidency: Banking Clean Air or Bucking EPA?
Originally scheduled to go into effect on January 1st, the rule would have required 27 upwind states to dramatically reduce sulfur dioxide and nitrogen oxide emissions by 2014.
