The city of Stamford has brought in Nexterra Systems to develop a biomass gasification system for the Stamford Water Pollution Control Authority.
“This project showcases the potential to transform the wastewater treatment industry into a major producer of renewable heat and power from waste fuels while maintaining the highest standards of water quality and public health,” said Jeanette Brown, executive director of the Stamford Water Pollution Control Authority and vice president of the Water Environment Federation. “We are very pleased to have selected such a strong technology partner as Nexterra, who has consistently demonstrated unparalleled excellence in technical innovation, commercialization and project deployment.”
Brown said Nexterra Systems, a supplier of biomass gasification technology based in Vancouver, British Columbia, will develop an energy system in conjunction with the Stamford Water Pollution Control Authority, which will supply Stamford with clean renewable thermal energy and reduce the city”™s fuel costs and carbon footprint.
According to Brown, the proposed gasification system will convert locally procured woody biomass waste into clean burning synthetic gas or “syngas.”
The syngas will be used to displace approximately 77 billion BTU”™s each year of natural gas currently utilized by the SWPCA to dry wet biosolids in an existing biosolids dryer manufactured by Andritz Separation.
Brown said by selecting Nexterra’s gasification technology, Stamford projects that it will lower its fuel costs by up to $1 million per year and reduce its greenhouse gas emissions by approximately 4,000 tons annually, the equivalent of taking 1,000 cars off the road.
The project is scheduled for completion by the end of 2010 and will be funded by U.S. Department of Energy grants and matching funds from the Stamford Water Pollution Control Authority.
