Go online and research “Vermont gasifier” at the National Renewable Energy Laboratory (NREL) Web site. Write a paragraph on how it was developed and who developed it. Include the significance of its development and why it is an R&D 100 Award-winning gasification system.
What will be an ideal response?
As stated in the “Project Update on the Vermont Gasifier,” it was
developed by partnership between the Burlington Electric Department
(host), the U.S. Department of Energy, Battelle, NREL and Future Energy
Resources Corporation (FERCO) for the purpose of verifying the design and
operation of an intermediate-sized gasifier, a plant that can use biomass
to generate energy. As visualized in Figure below, the gasifier works by
combusting wood chips with hot sand to produce biogas, which can be
used as an energy source.
Since this gasifi er does not require pure oxygen, it costs much less to build
and operate than other gasifi ers. Steam replaces oxygen. It also processes
biomass more quickly and it works under low-pressure compared to
other ones.
