Setting Up An AD Project: Lucy Lewis, BiogenGreenfinch Setting Up An AD Project: Lucy Lewis, BiogenGreenfinch Presentation Transcript

  • Setting Up an Anaerobic Digestion Project Lucy Lewis Innovation Manager 17th March 2009
  • Presentation Agenda •BiogenGreenfinch •Basics of anaerobic digestion •Applications of anaerobic digestion technology •Where to start & what needs to be addressed;  objectives  feedstock  biogas utilisation  digestate utilisation  planning  permitting  plant design & technology provider
  • BiogenGreenfinch • Bringing together the expertise of BIOGEN – UK’s leading AD operator with Greenfinch – UK’s leading AD technology provider • British, family business with 30+ years of experience within the AD industry • Team of 47 people based at either Milton Ernest and Ludlow • Capability and capacity to deliver a fully integrated AD solution to the agricultural, food, waste and water industries and to local authorities • Responsible for the development of 14 plants to date throughout the UK
  • Anaerobic digestion: a natural biological process Biogas Biomass Biofertiliser 37oC
  • Biomass for AD Livestock Manure Energy Crops Food Waste Sewage Sludge Glycerol
  • Heat 85% Biogas 60% CH4 Boiler 40% CO2 15% Losses Electricity 38% Biogas 47% Heat CHP Losses 15% Biomethane Biogas Upgrade CO2, H2S, H2O
  • Biogas CH4 CO2 Biomass Biofertiliser AD (N, P, K, C) (N, P, K,C)
  • Application of AD Manure Energy Crops Sewage Biodegradable Sludge Waste Reduce Improve Diversion Renewable Odour Nutrient from Energy Management Landfill Production
  • Biogas Plant in Kerala
  • Ryegrass Biogas in Shropshire
  • Sewage Sludge Digester
  • Co-Operative Biogas Plant in Denmark
  • Two types of AD plants developing On-farm Plant  manure  farm waste  energy crops Commercial Plant  municipal food waste  industrial food waste
  • What needs to be addressed? •Project Objectives •Feedstock •Biogas Utilisation •Digestate Utilisation •Planning •Permitting •Plant design & technology provider •Finance •Plant operation
  • What are your project objectives? •Make money •Diversification •Enhance existing slurry management •Import nutrients •Energy production •Self sufficiency •Green credentials
  • On-farm biogas plants Southwest Scotland
  • Feedstock •Type & quantity of feedstock?  On farm wastes & products  slurry- how long are animal housed?  what are the animals bedded on?  energy crops- do you have sufficient ground to grow in addition to animal feed?  what is the cost of crop production?  Imported feedstocks  ABP?  availability & seasonality?  feedstock guarantee & contract?  cost or gate fee?
  • Biogas Utilisation •CHP  Electricity- used on site or exported to the grid? Price per MWh?  Heat- is their a use on site or could it be exported? Price per MWh?  Tri-generation- production of cooling using surplus heat  Connection to the national grid- contact DNO. •Upgrade to biomethane  connection to gas grid - contract for biomethane, price per MWh  use as a vehicle fuel
  • Digestate Utilisation •Where will the digestate be utilised?  Is there enough land locally?  How much will the haulage cost?  When will the digestate be applied?  What storage is required?  Is a permit required for its application to land?  What cost is offset through less requirement for imported fertilisers?
  • Process Design Feedstock Process Digestate Energy
  • Plant Design & Technology Providers •Plant design  Tank design  shape, material  Mixing system  mechanical, gas, liquid recirculation  Heating  external / internal  Digester feeding & discharge  pump, auger, gravity  Gas collection •Budget costs •Tendering process
  • Planning •Will you get planning permission?  AONB, Greenbelt? •Where should you apply to for planning permission?  County Planning Authority  Local Planning Authority •What should be considered?  Odour,  noise,  vehicle movements,  proximity to dwellings,  aesthetic appearance, etc
  • Permitting •Animal Health Agency •Environment Agency •Planning Authority •Ofgem
  • Finance •Self finance •Bank loans •Joint venture
  • Plant operation & maintenance •Operate with current labour units •Employ additional labour units •Contract our specialist maintenance •Contract out plant operation & maintenance
  • Conclusion •Is the project viable & does it meet your objectives? •Plan carefully •Do not under estimate the project planning time
  • Thank you
