Generating
Electricity with Biomass Fuels at Ethanol Plants (RD-56)
This project focuses on
evaluating alternatives for using biomass fuels (DDGS or other
ethanol coproducts and/or corn stover) to generate electricity
and process heat at ethanol plants. We believe this approach
can positively impact key issues affecting the ethanol industry,
such as
- High energy (especially natural gas)
prices
- Potential interruption in natural gas supplies
- Eroding prices
for conventional coproducts
- Availability, reliability, and
cost of electricity from the grid
- The renewable energy balance
for ethanol production
- Potential to deliver “firm”, renewable (green)
electricity to the grid
Alternatives to be evaluated include:
• Current technology - natural gas for process
heat and electricity from coal or natural gas.
•
Biomass
(DDGS, cornstover or combination) to provide process heat
(PH) only by combustion or gasification.
•
Biomass (DDGS, cornstover or combination) to provide
process heat and plant electricity (CHP) - waste heat
from electric generation at temperatures sufficient to produce
process steam.
•
Biomass (DDGS, cornstover or combination) to provide
process heat, plant electricity, and electricity to grid
(CHPG) - amount based on using all waste heat for process
steam.
