On Monday, as First Wind announced its 69-MW Kawailoa Wind Project had gone into commercial operations on Oahu, other news underscored the difficulty the island state faces in trying to substitute renewables for expensive, imported fossil fuels.

A reconsidered proposal issued by the U.S. Environmental Protection Agency (EPA) on Friday sets out slightly weakened emission limits for mercury, particulate matter (PM), acid gases, and certain individual metals for future coal- and oil-fired power plants.

A decision by the Environmental Protection Agency (EPA) to impose new pollution limits on three coal-fired power plants in Arizona on Friday drew criticism from state officials, who said that the costly measure, which overrides the state’s regional haze plan, is designed to protect visibility, not public health.

Despite a last-minute lawsuit filed by California’s Chamber of Commerce, the state on Wednesday held its first auction of carbon emissions permits, kicking off the nation’s first state-implemented cap-and-trade program that limits the amount of greenhouse gases (GHGs) emitted by power plants, oil refineries, and other entities.

FuelCell Energy Inc. on Monday announced an order from its South Korean partner, POSCO Energy, for 121.8 MW of fuel cell kits and services to be manufactured at the FuelCell Energy production facility in Torrington, Conn. The company said this represents the largest order for both its company and the fuel cell industry.

Renewable energy projects installed on potentially contaminated lands, landfills, and mine sites have increased by 40% since 2008, a new list released last week by the Environmental Protection Agency (EPA) shows. Solar photovoltaic (PV) systems make up the bulk of about 184.7 MW installed at 60 sites in 25 U.S. states.

On June 15, in response to a court order, the U.S. Environmental Protection Agency (EPA) proposed new lower limits on particulate matter (PM) emissions that are scheduled for release in mid-December, although that deadline may be missed. Even with implementation delays, now is a good time to start paying closer attention to the requirements of the proposed standard.

The latest Environmental Protection Agency mercury control limits in the Mercury and Air Toxics Standards present a significant technical challenge to the power industry. Shaw offers a cost-effective process that promotes mercury oxidation and removal in fossil fuel combustion applications that can potentially achieve consistent mercury oxidation above 95%. Shaw’s E&I Group EMO technology provides the industry with an alternative to halogen salt addition and activated carbon injection that can also be used to augment the performance of existing Hg control applications and strategies
