Utilities And Power Markets

Purchasing Power From On-Farm Digesters
Neil Kennebeck, Dairyland Power Cooperative
Overview of Dairyland Power Cooperative and its program with anaerobic digesters will be highlighted in this presentation. Dairyland Power provides wholesale electricity to 25 member distribution cooperatives and 16 municipal utilities across Wisconsin, Minnesota, Iowa and Illinois. It is currently working with 8 digester projects, including a 200-cow dairy in Wisconsin generating 45 kW of power. A discussion of various sizes of dairy farms the utility works with, and the type of logistics needed to bring these projects onto the grid, will be discussed.

Facilitating Digester Development In Sacramento County
Marco Lemes, Sacramento Municipal Utility District
The Sacramento Municipal Utility District (SMUD) has partnered with two digester project developers to implement two new dairy manure digesters in Sacramento County. Both projects will use reciprocating engines coupled with electric generators (gensets) to generate electricity locally. All the electricity will be added to SMUD's grid under power purchase agreements (PPAs) with the developers. The two projects will use Selective Catalytic Reducers (SCRs) for NOx emission control. The projects will add to the two existing, operating digesters in the county. SMUD was awarded grants from the US Department of Energy (USDOE) and the California Energy Commission (CEC) and is disbursing these funds to the developers through a subrecipient contract. In addition, SMUD is providing long term PPAs and interconnection agreements; help with project grid interconnection, attainment of air emissions and water discharge permits, obtaining lease agreements with the farmers; general guidance on project technical and economic issues and other types of support. This presentation will present the status in the development of these projects, focusing on the economic challenges along the way.

Bio-Sourced Electricity: Utilities' Perspective
Jay Hasheider, Columbia Water and Light
Columbia Water and Light, a municipal utility in Columbia, Missouri owns a landfill gas (LFG) to-kWh plant (at the city operated landfill) and also is a purchaser of electricity from an LFG plant in Jefferson City, Missouri. Additionally, the utility is involved with bio sources used to generate power at its local 38 MW generation plant. Presentation discusses development of the bioprojects and deliverables over the past four years of operation. Discussion includes a brief comparison to other renewable based power, solar and wind, as well as a proposed biobased project that would involve significant expansion of biofuel use at the power plant based on regionally produced products compressed into a densified fuel that is comparable to coal.

Biomass Assessments

Strategic Bioenergy Feedstock Assessment
Gary Radloff, Wisconsin Bioenergy Initiative
Too often biomass assessments only provide a snapshot in time of overall state feedstock quantity. To better filter out barriers and opportunities and to see what makes strategic sense for Wisconsin, the Wisconsin Bioenergy Initiative (WBI) looked at a combination of biomass quantity, quality, price factors and conversion technology. First, a review of the existing literature on biomass quantity studies was done along with other relevant topics. The research team completed extensive biomass quality analysis to match up feedstock with best production uses. Finally, a robust price analysis was done in the woody biomass sector to make sure consideration was given to the highest and best use for wood products and economic growth. The research team then took all this work to examine regional or even local opportunity for biomass energy site locations.

Evaluation of Sustainable Biomass Sources To Produce Fuel and Power
Ferman Milster, University of Iowa
A grant from the Leopold Center for Sustainable Agriculture is funding a project to evaluate sustainable biomass sources to produce fuel and power. A planning team consisting of representatives from US EPA, US Fish & Wildlife, Natural Resources Conservation Service (USDA), US Forestry Service (USDA), Iowa State University, University of Northern Iowa, the Johnson County Conservation Board, the Amana Society, Iowa Farm Bureau, John Deere, the Iowa Department of Natural Resources and the Iowa Department of Agriculture and Land Stewardship. Seven working groups have been established to address the issues of fuel procurement; pricing; logistics and fuel yard needs; fuel preparation; the availability of industrial wood and fiber residuals, timber stand improvement and invasive species removal for fuel sources; impact on ecological services; and policy implications. Factors being evaluated include use of existing, residual wood and industrial wastes, material from timber stand improvement, removal of fast growing species (to enhance wildlife habitat), use of urban trees removed as a result of emerald ash borer or other insect or disease infestation, and dedicated energy crops such as poplar, mixed species prairie grass, switch grass and miscanthus.
 
Livestock Manure Production And Utilization Data Analysis
Mark Jenner, Biomass Rules
Manure utilization has been hampered by legitimate economic and cultural barriers.  Even so, manure producers are finding ways to add value to their livestock feeding operations by pulling their production leftovers back into their revenue streams.  It isn't simply a renaming, but a reprocessing and conversion.  Today sufficient data exists to illustrate that this is not simply a good idea, but it is what has already been happening.  Current efforts set out to illustrate that manure is already being used in profitable, environmentally-beneficial ways. By meeting existing demand for energy, nutrient, and fiber, costly surpluses of unwanted animal waste will go away.

European Experience And Insights

Integrating Partial Digestion Into Composting Operation
Norma McDonald, Organic Waste Systems, Inc.
The DRANCO installation in Hengelo (The Netherlands) is a state of the art example of partial stream digestion. The first intensive composting step was replaced by an anaerobic digester with capacity of 55,000 tons. Digestate is mixed with the woody fraction prior to aerobic composting. This integration enables the plant to treat more biowaste on the same site. The plant has become a net energy producer instead of an energy consumer, ensuring continuity of the installation.

Anaerobic Digestion of SSO — Lessons Learned from Europe

Ljupka Arsova, Gershman, Brickner & Bratton Inc.
Organic waste makes significant portion of MSW, from around 30% in high-income countries (13.9% of food scraps and 13.3% of yard trimmings in the US) to more than 60% in low income countries. This paper examines source separated organics (SSO) management systems in Europe through the established system in Barcelona and the rapidly developing system in the UK. Regulatory, operational and financial drivers and challenges were reviewed and compared with the current situation in the US. The paper also discusses how the quality of SSO affects the capital and operational costs and the overall management system efficiency.

Compostable Bags At European AD Facilities — Technologies, Pretreatment
Rhodes Yepsen, Novamont N.A.
Presentation reviews designs of current anaerobic digestion technologies and pretreatment and processing options related to compostable bags. Case studies from European countries will be presented.

Managing Urban Organics Via Anaerobic Digestion
Michael Niederbacher, B.T.S. Italia
Two case studies of anaerobic digestion facilities in Italy that process the organic fraction of urban solid waste streams will be presented. One project codigests the organics with chicken manure. Feedstock receiving and depackaging, separation of inorganics, the AD systems and odor management will be discussed.

Community Energy Systems

Creation Of A Clean Energy Innovation Park
Serpil Guran, Kevin Lyons, Dave Specca and Rutgers EcoComplex and Margaret Brennan-Tonetta, Rutgers University
Innovative technologies based on biomass-to-energy pathways can provide viable and sustainable solutions if the feedstocks and emerging conversion technologies are carefully assessed. Factors to consider when examining sustainability include availability and environmental impact of local and regional feedstocks, direct and indirect land use effects, costs and return on investment, feasibility of current and emerging conversion pathways for energy and fuel production, and existing and needed infrastructure for sourcing feedstocks and distribution of energy products. The "Clean Energy Park" (CEP) is an evolving concept that can help to spur the development of a sustainable clean energy sector. It can take the form of a large scale, real estate based park or as a service based center that supports the development of emerging technologies and serves as a proof of concept and test bed model for these emerging technologies. These centers can provide verification services generating reliable data and information for investors, developers and government agencies. An alternate model can start with an-existing post-industrial site with infrastructure and site development uses that integrate new technologies in renewable energy, waste recovery, water treatment and reuse into a sustainable asset for the community. Rutgers EcoComplex is a good example of the CEP center alternative model. It is located adjacent to a landfill and utilizes landfill-gas to energy technologies for heating and power. The EcoComplex promotes all alternative energy options, including biomass and waste to energy technologies, such as food waste recycling for renewable natural gas generation and utilization, electric vehicles (EV), and solar power generation. In addition, the center serves as a business incubator for alternative/ clean energy technology companies.
