Biomass Electricity Generation
at Ethanol Plants - Achieving Maximum Impact (RD3-23)
The current project builds on a previous
project,
also funded by the Xcel Energy Renewable Development Fund,
which evaluated alternatives for using biomass fuels
to generate electricity and process heat at ethanol plants.
There are significant opportunities to generate renewable “dependable” biomass-based
electric power at corn ethanol plants. The electricity is renewable
because locally collected/produced biomass is used for production.
The electricity is dependable because plants operate 24 hours
per day, 7 days a week for 330 to 350 days per year.
This project will focus on improving performance of
biomass generated electricity at ethanol plants and removing
barriers for commercialization.
- Improving performance includes incorporating biomass
integrated gasification combined cycle (BIGCC) technology
to generate electricity at ethanol plants. It also involves
integrating
super-heated steam drying technology in the ethanol process
to save energy and reduce water use.
- Removing barriers for
commercialization includes development of a business model
to use biomass co-products from the ethanol
plant as well as other biomass (e.g. corn stover) to provide
electricity to the plant and grid, and process heat to the
plant. It also involves evaluating technical and economic
feasibility of biomass procurement systems for corn stover.
Providing outreach and education for investors, policy makers,
utilities and the public is an important component of the project.
