Renew Energy (www.renewenergy.dk ) is a Danish biogas engineering/operations company. Renew has successfully designed and operated several silage biogas projects across Europe and the United States. The following selected references were executed by Renew Energy A/S and/or by Renew’s principals. Renew has 20 years of experience in international biogas projects with organic feedstock. In all projects, Renew was responsible for start-up operations, running-in and training of operators as well as ongoing services for optimization of plant operation, new feedstock etc.
  • EPC Contractor 5     Tibbar has retained Layne as its EPC contractor for the anaerobic digestion (biogas) and power generation components of the project Layne-Christensen is a $1 billion global construction company with over 6,000 employees www.layne.com Layne’s European partner, Entec, an Austrian biogas engineering company, has built over 200 commercially operating silage AD power plants. www.entec-biogas.com/en/ Layne has extensive experience with biogas projects and provides a full wrap guarantee with one year of operation.
  • Diversification of Renewable Energy Portfolio 6    Biogas generation from anaerobic digestion creates permanent jobs Wind and Solar provide intermittent power based on meteorological conditions while biomass provides continuous prime power. Tibbar’s Biomass project diversifies USVI’s renewable energy portfolio
  • Three components of a Biogas Operation 7 Biomass projects require three components: (1) Organic Feedstock (2) (3) Anaerobic Digestion Facility (to create biogas from the feedstock) Power Generation (converting biogas to electricity)
  • Biomass/Anaerobic Digestion Facility
  • How a Biogas Facility Works 9
  • What is Anaerobic Digestion and how does it produce power? 10 In the absence of oxygen, naturally occurring bacteria breakdown organic material (such as agricultural energy crops like Giant King Grass). This results in the creation of methane and carbon dioxide, which make up biogas. This process, called anaerobic digestion, occurs in large enclosed tanks. The biogas is collected from the anaerobic digestion tanks and is processed through a generator to produce renewable electricity.
  • Is Anaerobic Digestion currently being used as a Renewable Energy Source? 11     For the last 30 years, Anaerobic Digestion technology has commercially produced base load renewable energy (primarily in Europe) In Germany alone 3.8 million homes are fed power from organic feed Anaerobic Digesters Today over 10,000 plants operate in Europe in small towns and agricultural based communities The USVI’s fertile agricultural land and tropical climate make it an ideal location for a biomass project using agricultural energy crops.
  • Biogas Facilities in Europe 12
  • Examples of Silage Power Plants in Europe 13
  • Tibbar’s Biomass Facility on 15 acres of VI Port Authority’s property Land 14
  • 3-D Site Plan of Biomass/Power Generation Facility 15
  • Interconnection to WAPA 16
  • Site work has begun…… 17
  • Feedstock
  • USDA listed GKG as one of the Top 10 energy crops in 2012 19   Tibbar has the 20 year exclusive license for this product in the USVI The fresh cut silage would be cut on the farm and transported to and fed into the AD tanks daily Characteristics of Giant King Grass • High crop yield (90-150 tons/acre/year) • Drought resistant crop • Sustainably grown, not a food crop • Perennial grass • Not genetically modified • Not an invasive species • Needs sunshine, warm weather & rain or irrigation-no freezing • Fertilizer use is modest • No pesticide • Extensive bioenergy test data (2.7 cubic feet biogas/lb GKG)
  • Energy Crop Nursery in Operation on St. Croix 20 Nursery Planted 9/28/12 Second Nursery Planted 1/25/13 USVI Senator Judi Buckley
  • Plant GKG every 10 to 15 years 21
  • Giant King Grass Growing on St. Croix 22 45 days of growth after harvest
  • Silage Operations 23
  • Silage Operations 24
  • Farming with the Environment – Organic Fertilizer 25
  • Over 1,500 acres of Agricultural Land for Growing Giant King Grass 26
  • Agriculture Feasibility Team 27    Bioenergy Crops (www.bioenergycrops.com) One of the leading third party auditing firms and farm planning group for bioenergy crops Dr. Tony Provin, Professor of Agronomy Texas A&M Dr. Provin has been working on bioenergy crops in S. America, Brazil, and Caribbean for 20 years. John Carroll, agronomist for VIA SPACE Mr. Carroll launched GKG farm Hawaii and Nicaragua, Africa, among others
  • Power Generation
  • Four 3 MW Generators 29       Biogas generated through anaerobic digestion will be flow to four 3 MW Jenbaucher (GE) biogas generators. (Four generators allows for rotation with one spare available at all times.) Generators will produce 3.9 kW per 1 cubic foot per minute of biogas at 42% efficiency, 57% methane, and 550 BTU/ft3 Approximately 2,100 cubic feet per minute (cfm) of biogas will produce 8.5 MW to cover WAPA power and parasitic load The Generators contain carbon filter gas treatment, dehumidification system for moisture removal of biogas, and H2S filter media. Jacket water will be used to heat feedstock prior to anaerobic digestion Emissions from the generator will be less than 250 tons/year for all constituents.
  • Power Purchase Agreement (PPA) 30  Tibbar’s PPA/Interconnection Agreement was fully executed by the USVI WAPA on 7/24/13  The PPA is for 7 MW over 25 years with a 5 year option  The Commencement of Operations is June 30, 2015   Tibbar’s project is the only proposed biomass renewable energy project in the U.S. Virgin Islands. Tibbar has also obtained Qualified Facility (for Small Power Generation) approval from the USVI Public Services Commission.
  • USVI Government Partnerships
  • Project Benefits for the VI Department of Agriculture 32    Tibbar will develop a water harvesting program with multiple ponds on VIDOA land managing nearly 60 million gallons of run-off water. The community gardening program will reap the benefits from Tibbar farming operation through shared irrigation water and organic fertilizer leading to more consistent and higher yields at community farms. In addition, Tibbar will provide tillage services to local farmers eliminating the current back log.
  • Additional Benefits to the Dept. of Agriculture 33   The USDA cut the DOA hay program grants in 2012. Today it is challenging for the DOA to produce hay for all 3 islands and the program is at risk. Tibbar will take over this commitment and supply the 1000 round hay bales per year for distribution through the DOA
  • Project benefits for VI Waste Management Authority (WMA) 34    Tibbar’s biogas facility provides an alternative outlet to landfilling for several of WMA’s waste streams including:  Fats Oils, and Greases (FOG)  Food Waste  Bio-solids Using these streams as a feedstock for anaerobic digestion is common practice in Europe Tibbar’s agricultural operations provides a sustainable outlet for the WWTP effluent as irrigation water.
  • USVI Governor’s Visit to Denmark 35 On March 13, 2013 Governor John P. de Jongh, Jr. met with Tibbar’s partner, Renew Energy, to discuss the biogas project. The visit was part of the Governor’s Economic Development Tour to promote business opportunities in the USVI.
  • International Exposure 36 Tibbar and the USVI were featured in the September 2013 Biomass Magazine worldwide.
  • Overall Project Sustainability and Economic Benefits 37       Brands St. Croix/USVI as sustainable/green island(s) directly benefiting tourism Helps USVI reach its renewable energy goal of 22% by 2025 while producing 7 MW of base load cheaper, cleaner power Develop a commercial farming operation growing energy crops that will spur an agricultural renaissance Developed teaming agreements with VIWMA and DOA on St. Croix Creates over 35 high quality permanent jobs for the next 25 years Invests over $75 million in the USVI in 2013-2015
