Breen Energy Solutions and Headwaters Resources, Inc. have entered into a joint development and commercialization agreement for Headwaters Resources' Gas Phase Ammonia Slip Mitigation Technology. The patented technology is used at coal-fueled power plants to correct problems that can arise during the operation of emissions control equipment.

Coal-fueled power plants use Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) technologies to reduce emissions of nitrogen oxides. There are currently 259 SCRs and 172 SNCRs in service in the United States controlling NOx emissions from approximately 50 percent of the coal-fueled generation capacity. Additional SCR and SNCR systems may be constructed over the next decade to comply with increasing air emisions regulations.

During operation of SCRs and SNCRs, unreacted ammonia reagent can cause fouling of air heaters and other downstream components of power plant units and results in excess amount of ammonia that deposits on coal ash left over after combustion.

This condition, known as "ammonia slip," creates maintenance and operational issues for power plants including complications for handling the coal ash for disposal and beneficial use. The Headwaters Resources' Gas-Phase Ammonia Slip Mitigation Technology is designed to eliminate ammonia slip through the injection of oxidizers enhancing the performance of SCR and SNCR systems.

Under their agreement,Headwaters expects to provide technology and Breen will be responsible for developing the processes for implementing the technology in power plants.

"Headwaters Resources is a leader in managing coal combustion products in the coal-fueled utility power industry," said Cal Lockert, Breen Vice President of Business Development. "We are excited about the possibilities for teaming to bring this new mitigation technology to the market. It represents the partnering of two innovative organizations that are making a difference in plant emmissions control and reduction."

"We are delighted to partner with Breen in the next phase of ammonia slip mitigation

commercialization," said William Gehrmann, President of Headwaters Resources. "We believe that Breen's superior process engineering capabilities and position in the utility emissions control market will be invaluable in deploying this important technology."

The agreement includes a staged rollout including a series of full-scale demonstrations of the Gas Phase Ammonia Slip Mitigation technology. To date, Headwaters has conducted a series of successful pilot demonstrations including a power plant location.

Students Develop Cheaper, Greener, Alternative Energy Storage
Hoboken NJ (SPX) May 25, 2011
Every year, the world consumes 15 Terrawatts of power. Since the amount of annual harvestable solar energy has been estimated at 50 Terrawatts, students at Stevens Institute of Technology are working on a supercapacitor that will allow us to harness more of this renewable energy through biochar electrodes for supercapacitors, resulting in a cleaner, greener planet. Supercapacitors are comm ... read more
