Nexterra to develop biomass gasification
for wastewater treatment
Nexterra Systems Corp. has been selected by the City of Stamford, Conn., to develop a biomass gasification system for the Stamford Water Pollution Control Authority.
Sept. 15, 2009, Vancouver – Nexterra Systems Corp. has been selected by the City of Stamford, Conn., 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
gasification system will convert locally procured wood waste into clean burning synthetic gas (syngas). The syngas will be used
to displace approximately 77,000 MMBtu/year of natural gas currently
used by the SWPCA to dry wet biosolids in an existing biosolids
dryer manufactured by Andritz Separation. Using the
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 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
have been retained by Stamford to conduct independent reviews of the
project's technical and economic viability before Stamford proceeds.
