    Hi Mike,

    Several questions have come up that I would like you input on in regards to the green revolving loan fund in cases that might occur that do not follow the typical project pattern.

    Scenario 1) The energy farm reverts to another department at the completion of the grant of the Energy Biosciences Institute before the loan is repaid.  How would the loan be handled in cases where the new department weren’t within the VCR cost area? 

    • Since the loan is being repaid from the campus pool in favor of the VCR, it is likely that it would still pay out in favor of which other campus department it goes to.  Unless it turns into a self-supporting entity, which is unlikely.  In that unlikely event, the self-supporting entity would repay the loan.

    Scenario 2) A crop loss occurs one year that would limit/prevent the savings that are estimated from our initial estimates? 

    • The Campus utility pool would still pay out.  Just that the savings would not be recognized.  It would also pay for the additional propane.  The loss would not come out of the project.

    Scenario 3) Miscanthus ceases to be produced on the energy farm, resulting in no more mxg produced locally?  Would F&S then consider purchasing MXG from a local farmer who could supply the material? Assuming the boiler installed could handle multiple feedstocks, wood chips may be an alternative. 

    • We support this project because there is a research project attached to it.  If that project is discontinued, we would then have to discuss who repays the loan.  Most likely it would be out of the research fund, then, which would also pay for the restoration of the site and so on.  I don’t think we would be interested in providing alternative fuel sources or manage an abandoned research project.

    Thanks for your input.

  2. Marc Caluwe from Caluwe Biomass Heating Solutions in MA, US

    Subject: Quick summary and highlights from Marc's visit

    Just a quick summary of the discussions that occurred with Marc Caluwe from Caluwe Biomass  Heating Solutions in MA, US.

    Heizomat is the manufacturer that Marc is a representative for in the US.  I have several brochures that I can pass along that have details on the product line including the RHK-AK model that Marc recommended.  Key points of interest for this group in selecting / approving a boiler:

    • This unit utilizes a drag chain conveyor across the burn bed to handle / stir the material as it burns until dropping into an automatic ash clean out.
    • We discussed what emissions controls would be needed, and Marc indicated that would be a decision campus would have to address.  Marc will be forwarding a brochure that compares emissions values from several manufacturers in the UK.  Options in order of cost would be a cyclone and then an electrostatic reciprocator.
    • UL certification on this model is pending in approx. May of this year.  Due to the cost of ASME certification, they do not plan on testing to that standard.  Instead, in the US they run the boilers at atmospheric pressure with a vent on top.  In this configuration, a plate heat exchanger would be used between the boiler and a thermal storage tank (they recommend old propane tanks as acceptable).  The boilers when used in EU are rated and run at 2 bar (30psi).  Marc cited National Board Synopsis NB370 (http://www.nationalboard.org/index.aspx?pageID=409) that farms would be exempt from this requirement to run at atm.,  but universities / state / industry would not be.  It would be nice to get confirmation of this from engineering.
    • The boiler recommended has an infinite turndown ration (VFD on blowers) to 10% and then shuts down.  A hot air ignition system in used for lighting / relighting.
    • When running on MXG, in order to minimize clinker caused by low melting point of ash, a lower operating temperature is required, also requiring an 30% approx. upsize  in the model to get the rated output.  If we want 200Kw, we need to consider stepping up to a 250Kw model.
    • Material handling / storage / feeding was discussed at length, and Marc was going back to Heizomat to get their recommendations for the best system.  Heizomat does not offer a bale processor at this time, but has a bulk bin feed system to collect chopped material to be burned.

    Marc indicated that he would provide estimates (hopefully  by Friday noon) on a boiler system including a storage feed system, and also the same system installed in a cargo container, prewired, plumbed, etc.

    In addition to the discussions with Mark, Luis Rund presented a very nice plan / rendering of a cargo container size boiler housing that had glass fronts on one half for viewers, and the other half a biomass storage container.  Probably out of our price range at this point, but would make a nice travel display for shows, demos, etc.

    I also had a call later in the day from a representative of Biomass Energy Solutions in MO who is a sales rep for Uniconfort  (Italy) and we had very similar discussions on running at atmospheric pressures.  More literature is coming, and Jared Findley with BES forwarded some links I had looked at initially for the bale processors used for animal feedlots. 

    Let me know if you have any further questions or need clarification on above.

  3. F&S comment on solar house at Energy Farm

    Associated Project(s): 

    Collin has been involved in this project from the very beginning, so he should be involved in any further discussions on this project. I really want to ensure proper code compliance on this since it was not originally built nor inspected to verify adherence to the International Residential Code or the NEC. We are trying to renovate it to be considered to be a code-compliant single family residence. - Craig Grant

  4. Solar Decathlon 2011 Funding Agreement

    This proposal seeks to provide funding for student education centered around the University of Illinois’s participation in the 2011 US Department of Energy Solar Decathlon Competition. Each student team participating in this prestigious, international competition is required to build an entirely solar-powered 800 sq. foot house with innovative design features. This grant will provide funds for the development of new courses and enhancement of existing courses, provisioning of course materials and software, and the sponsorship of guest lecturers and consultants ($25,000), the employment of graduate students in coordinating roles for education and volunteer engagement activities ($15,000), and student travel associated with the competition ($10,000). The last UI entry in the Solar Decathlon competition engaged hundreds of students and was the highest-placed US finisher in the Competition; furthermore this participation will require the team to raise $700,000 at a time of severe campus budget constraints. Thus, the Student Sustainability Committee is in favor of funding this proposal in the amount of $50,000.
