2 MALAYSIA BIOGAS INDUSTRY

3 Palm Oil & Biogas Industry in Malaysia What if all Palm Oil mills produced Biogas? Location No. of Mills FFB (tons/yr) POME (m3/yr) Biogas (Sm3/yr) Energy (Btu/yr) Peninsular Malaysia Million 28 Million 670 Million 10.7 Trillion East Malaysia Million 21 Million 504 Million 8.1 Trillion Typical production ratios : Ratio of POME / FFB ~ 0.5 m3 POME / ton FFB Biogas productivity ~ 24 Sm3 Biogas / m3 POME Methane content in BioMethane ~ 50%

4 Biogas Industry in Malaysia What if all Biogas in Malaysia could be sold as gas heating? Biogas (Sm3/yr) Energy (Btu/yr) Gas Malaysia Average Selling Price (ASP) (RM/MMBtu) Annual Biogas Business 1,174 Million 18.8 Trillion RM 300 Million Note : Gas Malaysia ASP will steadily rise over the next few years as the Government reduce subsidy rate on natural gas.

5 GAS MALAYSIA BUYING & SELLING PRICE

6 Biogas Industry in Malaysia What are drawbacks of selling Biogas? Gas is sour and wet toxic, hazardous AND corrosive Gas flow is not consistent depends on mill production Gas quality is not consistent Methane content controls heating value Storing and/or delivering the Biogas half of gas stored/delivered is CO2!! Note : Numerous installations have shown that using Biogas for steam production is not feasible due to relatively low Biogas throughput compared to steam required at mill/refinery. FORGET ABOUT DIRECTLY COMMERCIALIZING BIOGAS

7 Palm Oil & Biogas Industry in Malaysia What if all Biogas is converted to Electricity and sold at Fit In Tariff (FIT)? Biogas (Sm3/yr) Electricity conversion efficiency Electricity Production (TWh/yr) FIT (RM/kWh) Annual RE Electricity Business 1,174 Million 40% RM 704 Million Note : According to KeTTHA, Biogas accounts for about 2 MW of grid-connected Renewable Energy (RE) presently. Forecast maximum electricity generation from Biogas is 410 MW. FIT is complex and structured. Maximum FIT is used in above calculations (RM0.32/kWh for LV supply upto 4MW). FIT is depressed at 0.5% annually. Several countries offer Enhanced FIT, which is higher than consumer tariffs, but Malaysia does not offer this Source : Malaysia Energy Centre website.

8 Biogas Industry in Malaysia What are drawbacks of producing Biogas-based Electricity? Gas is sour and wet needs pretreatment otherwise generators will corrode Gas flow/quality is not consistent instability in electricity supply & therefore revenue Malaysia does not subsidize RE Electricity. Also FIT rate is annually depressed at 0.5% - annually declining revenue, opposite to selling price of natural gas in Malaysia, which is forecast to annually rise Capacity problem few palm oil mill/refinery has enough Biogas capacity to justify installing electricity generation facility to tie-in to local grid. VIABLE BUT COMMERCIALLY CHALLENGING FOR MOST MILLS

9 Biogas Industry in Malaysia What other possible commercial use of Biogas? Purification to BioMethane alternate to CNG and LPG fuel Recovery of BioCO2 valuable gas in industrialized states GasAlam process treats Biogas to produce BioMethane and BioCO2 SIMULTANEOUSLY Concentration of both gases are controlled to allow direct compression of BioMethane (for storage and distribution) as well as for liquefaction of BioCO2 (for storage and distribution). Simultaneous revenue from sales of two gases in one facility.

11 Typical Biogas to Energy Plant Typical plant involves anaerobic digester, biogas feed to power generator, excess gas flaring and exhausted waste disposal. Biogas Gas Blower Flare Flue Gas Electricity Gas Engine G Fresh POME Biomass Slurry Conveyor / Pump Digester Heat Exchanger Heat Cooling Unit Generator Circulate Material Digested Material Recirculation Pumps Slurry effluent

12 GasAlam Gas Purification System Biogas Digest er Gas Blower Flare Gas Engine Heat Flue Gas G Electricity Generator GasAlam incorporates Gas Purification System to typical Biogas Facilities to increase overall performance and economics. Proprietary GasAlam Gas Purification System Cooling Unit Recirculation Pumps Slurry effluent

13 Overall Schematic of Advanced Biogas Process Advanced Control System Moisture & H2S Removal Generator Electricity BioMethane Gas Separation BioCO2 Palm or other biomass waste Digestor

14 GasAlam Integrated Biogas Technology Green degradation of palm oil mill waste and other organic waste GasAlam facilities incorporate gas purification process for production of BioMethane for industrial use. Integrated control system optimizes production of electricity based on actual demand and diverts excess gas for BioMethane and BioCO2 production. The overall system can be controlled to produce more Electricity, more BioMethane or more BioCO2, depending on consumer requirements and local industry economics. This results in overall ZERO flaring. Total removal of detrimental GHG to atmosphere is possible and CDM claims are tangible.

15 FINANCIAL MODEL OF INTEGRATED PLANT

16 Benefits of GasAlam Integrated Biogas Facility Generation of Electricity for inhouse use or commercial Electricity selling price = RM 0.32 / kweh Generation of pure Methane gas - sales CNG is priced at about RM 0.60 / Sm3 under heavy government subsidy. LPG is priced at about RM 3.60 / Sm3 (non-domestic) Generation of pure CO2 gas possible sales Carbon credit possible additional revenue (not considered here)

17 Financial Model Electricity Sales Basis : 900 Sm3/hr Biogas POME = 40 m3/hr Biogas = 900 Sm 3 /hr Generator Electricity 1800 kweh BioC1 0 Sm3/hr Gas Separation Est. Investment Cost = RM 36.0 MM Annual Revenue = RM 4.5 MM Payback > 10 years BioCO2 0 Sm3/hr

18 Financial Model Gas Sales Basis : 900 Sm3/hr Biogas Biogas = 900 Sm 3 /hr Electricity 400 kweh POME = 40 m3/hr Generator BioC1 500 Sm3/hr Est. Investment Cost = RM 38.0 MM Annual Revenue = RM 10 MM Payback < 7 years Gas Separation BioCO2 350 Sm3/hr

19 ADVANCED BIOGAS PROJECT STRATEGY

20 GasAlam Integrated Technology Prior to use of Biogas, it has to be sweetened and dehydrated. This is to reduce toxicity and corrosiveness of the gas BioMethane can be produced by separating Methane from the Biogas. The raffinate is gas rich in CO2, which is source for producing BioCO2 The heart of the process is a proprietary Pressure/Vacuum Swing Adsorption system, operated in cyclic-steady state mode The Unit is constructed using a 2-column or 4-column setup. The Unit is controlled using a programmable controller for automatic, unmanned operation The technology can be configured to produce more BioMethane or more BioCO2, after producing in-house electrical requirements if any BioMethane produced is then compressed, stored and delivered to regional consumers. BioCO2 is liquefied, stored and delivered to regional consumers

21 GasAlam Integrated Technology The project basis is of mutual benefit between Mill (Biomass Owner), local industry and community Facility Owner can provide POME OR provide Biogas. Space shall be provided for the installation of the requisite gas purification equipment The Biogas shall be mainly used for BioMethane and BioCO2 production The gases so produced are owned and distributed by GasAlam or can be jointly commercialized with Facility Owner, based on equity participation The integrated project is typically undertaken on a BOO (Build, Own, Operate) basis On EPC basis, all facilities shall be owned by Owner, except for the BioMethane / BioCO2 Purification Unit, which shall be owned and operated by GasAlam on a lease-use basis. GasAlam shall operate and maintain gas purification plant.
