1 Managing Risks, Reaping Rewards Through Biogas Power Generation Securing success in POME biogas power generation Biogas AP Forum June, 2014 Kuala Lumpur, Malaysia John C Y Lee, Steve Szymanski, Michael A Devine Contact: johncylee@cat.com Caterpillar Inc.

2 Managing Risks Fuel (reliability, quality, price) Revenue (energy sales or savings) Technology (equipment track record, performance, efficiency) Operations (uptime, ease and availability of operation and maintenance) Construction (schedule, plant performance, cost) Credit (financing, debt payment) Insurance (physical damage, public liability) Permitting (environmental, noise, structure, etc.) Inflation (for both revenue and expense) Page 2

3 Risk Identification, Mitigation and One powerful future. Management Developer Sponsors / Shareholders Lender (debt) Loan and Security Agreement Off-Taker(s) Power Purchase Agreement, Special Purpose Project Company (Borrower) Operator Operations & Maintenance Agreement General Contractor Engineering, construction and procurement Gas and Power Generation Equipment Feedstock Supplier Insurance Legal Framework Law and Regulation Legal Agreements Each Agreement and each relationship contains risks All Agreements must work together, be consistent, and not be in conflict Page 3

4 Risk Allocation Each risk must be assigned to the party who is best prepared to manage it! Operational risk Operator Credit risk Lender Construction risk (schedule, plant performance, cost) Engineering, Procurement and Construction Contractor (EPCC) Physical damage, public liability Insurance company Fuel supply risk Gas company Each contract must have appropriate compensation for failure to perform Page 4

9 Continuous Stirred Tank Reactor (CSTR) One powerful future. Advantages High concentration of TS: 8%~12% Optimized mixing with mixers Large capacity and high biogas yield Easy maintenance Page 9

10 Expanded Granular Sludge Bed (EGSB) One powerful future. Advantages High SS content High COD removal rate Resistant to changes in loading Small footprint Page 10

11 CSTR Mixer Advantages Customized, innovative mixer with energy consumption per volume of digester reduced from typical 10 W/m 3 to 4 W/m 3 Page 11

Desulfurization or H 2 S Scrubber The concentration of H 2 S in the raw biogas can be decreased to less than 100 ppm by typical desulphurization process.

12 Desulfurization or H 2 S Scrubber The concentration of H 2 S in the raw biogas can be decreased to less than 100 ppm by typical desulphurization process. The removal efficiency can be over 95%. Advantages Lower operating cost Higher removal rate Resistant to changes in loading Easier to start-up and to operate Simple automated system Page 12

which biogas is stored The gas holder is equipped with EX rated blower which is used to regulate the amount of gas

13 Gas Storage Double-membrane gas holder is made of outer membrane, inner membrane and bottom membrane The outer membrane is the ballshaped gas bag The inner membrane and the bottom membrane together compose a compartment in which biogas is stored The gas holder is equipped with EX rated blower which is used to regulate the amount of gas and keep a balance of the air pressure in the gas holder Proper inflation can also provide protection to bad weather Page 13
