2 Agenda Why Energy from Waste Why Gasification of Waste Waste Gasification Project Aims Waste Gasification FEED Study Outcomes Waste Gasification Feedstock Preparation The Waste Gasification Market Potential Waste Gasification buyers, Investors 2.

3 Why Energy from Waste UK Waste Strategy The waste hierarchy, local management of waste European focus on waste and EC 2025 Landfill Directive (35% reduction of biodegradable waste to landfill by 2016, and ban from ETI undertook a 1 ½ year research programme investing 1.4m identifying the following; Between 2 to 4% of UK energy in 2050 from waste streams Technology acceleration opportunity for gasification/gas clean up at the smaller scale UK opportunity cost up to 5.5 billion, based largely on avoided emissions (ETI s Energy Systems Modelling Environment) City Town Village Rural Av Population 500,000 50,000 5, % UK Popn. 34% 43% 21% 2% Waste kte/yr Number of plants ,544 4,544 3.

4 Technology Choices Incineration and Anaerobic Digestion TRL 9 (Actual system operated over the full range of expected conditions). Pyrolysis and Gasification TRL5 (Laboratory scale, similar system validation in relevant environment) But, Gasification; Can handle a wider range of waste without pre-sorting Provides great energy sector flexibility (power, gas, liquids) Is future proof, as an intermediate and destination technology Greatest potential for ETI to deliver LCOE and efficacy improvements Coupling of key elements (Sorting, gasification, gas clean up, gas utilisation) of the system are vital 4.

5 Overall Project Aim Waste Receipt - MSW/C&I/Biomass Waste sorting - Dry/Wet Integrated Gasification Gas clean up Gas Utilisation - Gas Engine/Turbine Project Objectives Demonstrate capability for a 5-20 MWe Waste Gasification to energy facility Project driven by performance targets - 25% Net Electrical Efficiency over entire operation - 80% availability - Combination of UK typical waste (MSW, C&I), & limited amount of biomass Phase 2 - One consortia selected to continue to detailed design, construct and operation of a demonstration facility 5.

6 Phase 1 FEED Study Risk investigation Site Planning consent FEED study Market analysis Investor analysis Feed stock testing Future energy vectors Engineering design review Future funding investigations Feed stock preparation Feed stock availability 6.

7 Questions we asked about feed stock preparation Should the plant incorporate a MRF, MBT? What fuel flexibility should the plant have? Measure the performance on the following and determine options? SRF RDF Biomass 7.

8 Competitors Investor Technology choice Raw material Outputs Wind combustion landfill CfD (Electricity) Solar AD Compost BioSNG Biomass Gasifier EFW Hydrogen Waste Pyrolysis Export Fuels / Chemicals 8.

9 Who might the buyers be? Who selects technology? Merchant plant operators County council contract operators Energy customers Business parks Large manufacturing sites District heating Investors Pension funds ESCO 9.

10 What did we find during our due diligence By paying for a FEED study the following areas where clarified and hence reduce the risks in delivery Greater cost certainty Provides clearer risk analysis The value of claims made was established Feedstock handling, while not difficult, is a key challenge Different approaches taken to maximise system availability There is limited whole system operating experience Tars is a complex subject good understanding of control is essential Key understanding of waste properties and how they vary is needed Investors are finding it challenging to take on new designs of gasification system due to low operational evidence 10.
