Nexterra selected by the City of Stamford Connecticut to develop biomass gasification system for municipal wastewater treatment facility



    VANCOUVER, Sept. 10 /CNW/ - Nexterra Systems Corp. (www.nexterra.ca), a
leading supplier of biomass gasification solutions announced today that it has
been selected by the City of Stamford, Connecticut to develop a biomass
gasification system for the Stamford Water Pollution Control Authority
("SWPCA"). The energy system will supply Stamford with clean renewable thermal
energy that will reduce Stamford's fuel costs and carbon footprint.
    The proposed Nexterra's gasification system will convert locally procured
woody biomass waste into clean burning synthetic gas or "syngas". The syngas
will be used to displace approximately 77,000 MMBtu/year of natural gas
currently utilized by the SWPCA to dry wet biosolids in an existing biosolids
dryer manufactured by Andritz Separation. 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
system will be designed to meet or outperform local air emissions standards.
    To implement the project - scheduled for completion by the end of 2010 -
Nexterra plans to collaborate with strategic alliance partner Andritz
Separation. The project will be funded by U.S. Department of Energy grants and
matching funds from the SWPCA. Financing costs associated with funds to be
invested by the SWPCA will be more than offset by energy savings that will be
realized from the project. Two engineering firms, Aecom and HDR have been
retained by Stamford to conduct independent reviews of the project's technical
and economic viability before Stamford proceeds.
    Once this project is successfully completed, Stamford may proceed with
future phases that will be developed and assessed on their own technical and
economic merits. These include a possible second phase of the project to
provide a closed loop renewable energy solution, enabling the SWPCA to use dry
biosolids as the fuel source for the gasification system. In a possible third
phase, Nexterra and SWPCA may develop a second gasification system that would
convert dry biosolids into renewable electricity. Syngas produced by gasifying
biosolids would be cleaned, conditioned and fired into a GE Jenbacher internal
combustion gas engine. The resulting electricity would be sufficient to meet
SWPCA's on-site power requirements making it energy independent from the grid.
    "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 SWPCA 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."
    "We are delighted to have been selected to participate in this
ground-breaking project," said Jonathan Rhone, President and CEO of Nexterra
Systems. "We look forward to working with industry leaders like the SWPCA,
Andritz Separation and GE Jenbacher to create a new paradigm for the way the
municipalities manage urban biomass and wastewater residuals to achieve energy
independence."
