  • This project involves the growing of trial quantities of alfalfa for gasification pilot plant tests and the use of by-products of alfalfa plants as animal feeds for beef and dairy cattle and turkeys. The various tasks under this project are described. Tasks are: design; review and confirm feedstock supply plan; performance guarantees and warranties; sales contracts; site plan construction and environmental permits report; environmental monitoring plan; and project management, engineering, and administration.
  • This report describes the educational efforts made by Minnesota Agri-Power to provide education to the general public, to agricultural professionals and to growers. Information on the management of alfalfa growth, as well as sharing of research results were some of the information made available. The education program was accomplished by participation in: workshops for producers; professional conferences; field days and informational meetings for producers, educators, and Ag professionals; demonstrations; community meetings and information dissemination; fact sheets and management guides; internet information; press releases, publications, and publicity.
  • Program status and accomplishments for a project to develop alfalfa as a biomass fuel for power generation are summarized in this report. The main areas of reporting include: (1) alfalfa separation pilot plant testing, (2) design of gasification plant, (3) alfalfa leaf meal feeding trials and analysis, (4) integrated plant design and cost estimate, and (5) site plan construction and environmental permits. The alfalfa separation pilot plant fractionation equipment encountered operating problems from rocks and other tramp materials in the alfalfa bales. An investigation of techniques and equipment to remove the tramp materials resulted in the selection of a vibratingmore » conveyor system. The Carbona gasification plant design basis and the Westinghouse scope of supply and design basis for the hot gas filter are provided in the report. The alfalfa leaf meal feeding trials showed that this economically critical co-product can be a viable livestock feed ingredient if favorable price, availability, and quality are maintained. The Stone and Webster basis of design for the integrated plant is included, and the basis for development of gas turbine performance runs is also detailed.« less
  • The Minnesota Valley Alfalfa Producers propose to build an alfalfa processing plant integrated with an advanced power plant system at the Granite Falls, Minnesota industrial park to provide 75 MW of base load electric power and a competitively priced source of value added alfalfa based products. This project utilizes air blown fluidized bed gasification technology to process alfalfa stems and another biomass to produce a hot, clean, low heating value gas that will be used in a gas turbine. Exhaust heat from the gas turbine will be used to generate steam to power a steam turbine and provide steam formore » the processing of the alfalfa leaf into a wide range of products including alfalfa leaf meal, a protein source for livestock. This progress report describes feedstock testing, feedstock supply system, performance guarantees, sales contracts, environmental permits, education, environment, economy, and project coordination and control.« less
  • This report very briefly summarizes activities related to the use of alfalfa as a fuel for electricity generation. A pilot plant processing facility was obtained and operated during the reporting period. Power purchase agreements and contracts for research and development are noted. Other work included preliminary research of: (1) turkey breeder stock for livestock feeding trials with the co-product alfalfa leaf meal, and (2) USDA indices for power purchase pricing formulas.
