2 Bridge Energy Project Snapshot Tesco Superstore Project SPV Project Type Bridge Energy Ltd 500kW on-farm AD 280 unit housing development; under construction Primary Energy Electrical Promoter agriad Ltd Location Feedstock Technology Banbridge, Co. Down, Northern Ireland Grass silage, slurry, poultry litter Williams Industrial Services Tesco filling station; Point of connection to the electrical distribution networks Bridgewater Park; Outlet Retail Park, Tesco Superstore and retail/industrial units Investment 3.5m Lead Funder Project Status UK Green Investment Bank Operational; OFGEM ROC Accredited. Bridge Energy AD site. Route of dedicated electrical grid connection ~3MW and potential gas distribution pipeline Phase 2 Biogas upgrading to biomethane; 1,000,000m 3

3 International Farm Comparison Network (IFCN)

4 AD Projects currently operational or under construction in NI 90M to upscale from biogas to biomethane 1000 construction jobs 150 operational jobs 100m litres of imported diesel displaced per yr 55 to 60no AD Projects ~ 150m investment At least 75m spent locally 15m/yr of feedstock for 20yrs 7m/yr in operational services for 20yrs 1000 construction jobs 150 operational jobs created 30MW el capacity Potential for biomethane ~ 1.5m per plant to upgrade 1.8m litres of diesel displaced per plant upgraded

5 NI s Bio-methane Feedstock Potential Centre for Advanced Sustainable Energy Bio-methane as a vehicle fuel in Eugendorf, Austria Waste from food chain 500,000 tonnes of food waste generated annually in NI Can displace ~10% of current diesel consumption with bio-methane Feedstock from grass silage 1 hectare (Ha) of grass produces bio-methane equivalent up to 4,500 L of diesel 20% diesel displacement requires ~2% of total grass and crop land in Northern Ireland Total Impact: M to NI Economy Savings of M switching to Dual-Fuel technology (using natural gas or bio-methane) Using locally produced bio-methane rather than imported gas retains further ~ 200M in NI Dual-Fuel Vehicle Modelling 5

6 Weakness; Electrical grid saturation. Potential major capital expenditure required. Opportunity; Is there a smarter way of doing this?

7 CASE Proposal; Biomethane and a Smart Sustainable Rural Energy Infrastructure How the electrical grid was designed Electrical Grid Unbalanced Net import; But grid designed to do so 33kv 11kv Load Demand Load Demand Load Demand Load Demand

8 Biomethane and a Smart Sustainable Rural Energy Infrastructure How the electrical grid operates currently Electrical Grid Unbalanced Net export; Grid not designed to do so 33kv 11kv Wind blowing AD 500kW CHP Load Demand Variable Constant Variable Generation greater than demand

9 Biomethane and a Smart Sustainable Rural Energy Infrastructure How the electrical grid needs to operate now; Balance and demand by creating load at the local grid level. Smart energy infrastructure. Electrical Grid Balanced 33kv 11kv Wind blowing AD 500kW CHP Load Demand transport Variable Constant Variable Biogas upgrading and biomethane compression Additional load created. Demand balances

10 Biomethane and a Smart Sustainable Rural Energy Infrastructure How the electrical grid needs to operate now; But balancing of the local electrical grid is difficult to achieve with variable. Electrical Grid Unbalanced Net import; Increased demand on transmission network 33kv 11kv Wind not blowing AD 500kW CHP Load Demand transport Variable Constant Variable Biogas upgrading and biomethane compression Additional load created. But demand greater than

11 Biomethane and a Smart Sustainable Rural Energy Infrastructure How the electrical grid needs to operate now; Need to balance variable with smart on demand. Electrical Grid Balanced 33kv 11kv AD 500kW CHP Load Demand transport Constant On demand CHP Constant on demand CHP Constant On demand CHP Biogas upgrading and biomethane compression Additional load and created. Demand balances

12 Biomethane and a Smart Sustainable Rural Energy Infrastructure Biomethane as an energy carrier; Why compress air when you can compress energy Cow slurry Milk Milk Biogas upgraded to biomethane on farm heat transport of milk Biomethane On demand electrical from biomethane CHP Energy Crops farm vehicles process heat to dry milk transport of dairy products rural public transport Food processing waste
