Agenda

2.

• 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


Why Energy from Waste

3.

• 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 2025.

• 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)

Technology Choices

4.

• 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


Overall Project Aim

5.

• Waste Receipt

- MSW/C&I/Biomass

• Waste sorting

- Dry/Wet

• Integrated Gasification

• Gas Utilisation

- Gas Engine/Turbine

• Gas clean up

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


Phase 1 FEED Study

6.

• 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


Questions we asked about feed stock preparation

7.

• 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

Who might the buyers be? Who selects technology?

9.

• Merchant plant operators

• County council contract operators

• Energy customers

– Business parks

– Large manufacturing sites

– District heating

• Investors

– Pension funds

– ESCO


What did we find during our due diligence

10.

• 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
