1 Biogas in NI A Vision for 2020

2 renewable energy is the key to wealth creation Robert Brennan B9

3 Current roles - Who is Robert Brennan? 1. Instigated B9 Organic Energy International Ltd Landfill gas development in NI New Commercial AD plant at Dungannon (GECO) 2. B9 Energy Storage team member on new energy storage demonstration project for Isothermal Compressed Air Energy Storage (ICAES) a world first. 3. CASE (Centre for Advanced Sustainable Energy). Industry Chair for Biomass at this new centre of excellence for research on advanced renewables.

4 Content 1. Value to the NI economy from; Waste to energy (power and heat) Nutrient management (Nitrates phosphates and potash) Energy storage make renewables deliver energy when we needs it? 2. THE OPPORTUNITY - What is the potential for energy from renewables - in NI? Potential from biowaste Potential from wind Energy; are stable Energy costs deliverable? 3. ICAES a new technology Timing is everything energy when we need it 4. Conclusion Can we realise THE OPPORTUNITY?

5 Energy and the Economy Facts; Cost of energy up 100% in last 4-5 years What will be the increase by 2020 another 100%? Impact; Potential loss of jobs (to cheaper locations) How do we avoid this; Decouple industrial growth from fossil energy costs and replace with renewable energy Impact; From renewables I can provide a contract today at a fixed price for the next 10 years - will your current power provider do that? But can renewables deliver?

6 Energy and the Economy Some annual energy stats Max power demand in NI circa 1800MW Min power demand in NI circa 400MW Current (fossil fuel) energy costs are circa 1 billion. this is the value of the opportunity

7 Energy and the Economy Is there sufficient renewables to make a difference? Wind huge resource both on and off shore; Installed renewable capacity in NI is circa 500MW next (offshore) project is 600MW - limited by grid capacity and its intermittency Water huge resource - tidal and underwater current; next project is 200MW off Co Antrim coast. Waste (quite a lot!) -Energy from AD or thermal conversion; currently limited by procurement processes; no energy remit within either waste or agriculture policy! Lets look at the potential

8 The Energy Resource from (organic) waste NI (Northern Ireland) has an annual 12 million tonnes reserve of good quality biomass (otherwise described as biodegradable waste), that when digested in the absence of air (Anaerobic Digestion) in a biogas plant can yield in excess of 30% of its vehicle fuel demand, or 16% of its heat and power consumption. RICS years on still unexploited! - but about to change

9 Potential Energy from (AD) biological treatment (BIOGAS) Source of organic material Millions of Tonnes p.a. Current Method of Disposal Electricity Potential (in MW) Non intermittent Agriculture 9.7 landspread 71 Industrial / Commercial waste Municipal (Household) 0.5 Landfill/composting Landfill/Composting 22 Sewage Sludge 0.5 Incineration 5 Totals Source of Data DARD and Regional Waste Plans (Rounded Figures)

10 Taking Agriculture as an example - value of energy pa (with no energy crops included) Source/tonnage of Organic material Electricity Revenue.Millions Heat Revenue at. Millions Agriculture Cattle slurry 9,000, Pig slurry 350, Chicken litter 350, Totals

11 ADDITIONAL BENEFITS Resource Recovery of nutrients (NP,andK) In 2010 we imported 360,000 tonnes of synthetic fertiliser at a cost of 80 million Start using natural digestate (output from AD) as a local and natural substitute for the synthetic imports

12 Potential Energy from wind... NI has high wind penetration, with relatively low electricity demand, so the grid is overloaded at peak wind, resulting in wind farms being curtailed. (1,000 wind applications currently in planning in NI!) to open up wind power availability we need energy storage, interconnection and demand side management

13 ... we need a technology breakthrough..and we (and DECC) believe we've found one in Isothermal Compressed Air Energy Storage ICAES from LightSail The Proposal is; Take wind power off the grid and store the energy (which frees up grid capacity) Then release the energy at peak demand

14 Winter day - 1/2 hourly demand Co-incidentally 300MW Peak SELL hour duration 08/11/

15 ICAES lowest cost bulk electricity storage LightSail Energy 1 st gen product LightSail Energy v2 with underground storage Competes with conventional generation without subsidies. Half the price of batteries.

16 How dose it work? Compression is hot business as most of the (compression) energy lost as heat

17 Store heat as well as compressed air

18 Add waste heat to increase return trip efficiency Energy output at T / Energy output at T=15 o C Energy output at T Energy output at T=15 o C 100% Round trip efficiency If multiplied by 1.43 gives 70% Round trip efficiency Energy output at T/ Energy output at t=15deg C Get more energy output Use hotter water o C water T High [ C]

19 Timing is Everything energy available when it s needed A potential source of spare/waste heat is AD - the integration of Wind Power With energy storage And AD makes the entire system much more cost effective and critically removes the intermittency barrier and frees up grid capacity

20 First-Generation Product Shipping in Breakthrough Service Life Power Unit 500 kw modules 70% round-trip efficiency 20+ year lifetime Storage Unit 1 MWh modules Proprietary filament-wound tanks Shipping container from factory ASME certified

21 LightSail NI Ltd A new Northern Ireland based Joint Venture to serve the European, African and Middle Eastern Markets

22 Energy Storage Collaborative Network

23 Conclusion To realise the opportunity (for Energy); De-couple fossil fuel costs from economic growth Use biological treatment (AD) to optimise energy (and beneficial nutrient) recovery Employ smart technology (energy storage) to optimise energy delivery when needed Need leadership/ownership and policy change
