8 Biogas from Palm Oil Mill Effluent POME is a nearly untapped resources with great potential. Biogas from POME is commonly used to produce electricity (feed in tariffs), BUT: The large majority of mills are not within 10km of the grid. Feed in Tariffs can change. Biogas often produced in excess of the electricity need for the mill and surplus is typically flared. Potential for much larger volume of Biogas (EFB) Upgrading to Bio-Methane in addition to electricity generation increases the commercial value of a Biogas project.

9 Biomethane (CBG) Biomethane as direct replacement of Natural Gas or LNG. Feed to Grid (difficult due to lack of infrastructure) Sale to Industrial Parks (if locations of mills suitable) Use within Palm Oil operations (Hydrogen generation)

10 Business Case Model General conditions: Raw biogas 700 Nm³/h (continuous) Upgrading Process 2 stages Raw Biogas Methane 54.3% Upgrading Yield 94% BioMethane composition 98% Project Data: Depreciation Period 15 years Interest Rate 6% Diesel Price Non subsidized (RM 2.8 in MY; IDR 12,400 in ID)

Biomethane as natural gas alternative Biogas Plant Upgrading Compression & Storage SEPURAN Industrial Park, Grid, etc CH 4 Production (per Year): 112,800 mmbtu

11 Biomethane as natural gas alternative Biogas Plant Upgrading Compression & Storage SEPURAN Industrial Park, Grid, etc CH 4 Production (per Year): 112,800 mmbtu Upgrading/Compression/Storage: CAPEX: MYR 10.5 Million OPEX Yearly: MYR 1.2 Million Total Yearly: MYR 2.3 Million (incl. depreciation) Production Cost: MYR per mmbtu

12 Biomethane (CBG) Biomethane as fuel direct for replacement the plantation of trucks Natural (captive Gas or fleet LNG. use) Feed to Grid (difficult due to lack of infrastructure) Diesel Sale to is Industrial a substantial Parks part (if locations of the Operational of mills suitable) Expenses in the palm oil mill/plantation Use within Palm Oil operations (Hydrogen generation) Partial or full decoupling from diesel price volatility Not convincing Business Case for Malaysia at Today s Natural Gas subsidized price. Proven technology package and readily available technology CBG utilization benefits the mill directly = direct impact Full CBG or Diesel Dual Fuel options

Biomethane as Truck Fuel (Captive Use) 100% CBG Trucks Biogas Plant Upgrading CBG Compression and Distribution CBG Trucks SEPURAN Number of Trucks (5 10 tons): 94 Number of Fueling Stations: 2

13 Biomethane as Truck Fuel (Captive Use) 100% CBG Trucks Biogas Plant Upgrading CBG Compression and Distribution CBG Trucks SEPURAN Number of Trucks (5 10 tons): 94 Number of Fueling Stations: 2 Upgrading/Compression/Distribution/Conversion: CAPEX: MYR 21 Million OPEX Yearly: MYR 1.9 Million Total Yearly: MYR 4.1 Million CBG Production Cost: MYR 1.58 per Diesel Liter Equivalent Savings: MYR 3.3 Million per Year IRR: 25.2%

14 Biomethane as Truck Fuel (Captive Use) Diesel Dual Fuel Trucks Biogas Plant Upgrading CBG Compression and Distribution Diesel Dual Fuel Trucks SEPURAN Number of Trucks (5 10 tons): 156 Number of Fueling Stations: 2 Ratio CBG/Diesel: 60/40 Upgrading/Compression/Distribution/Conversion: CAPEX: MYR 19.2 Million OPEX Yearly: MYR 1.9 Million Total Yearly: MYR 9 Million (includes Diesel cost) Mixed Fuel (CBG/Diesel) Cost: MYR 2.03 per Liter Savings: MYR 3.5 Million per Year IRR: 27.9%

15 Summary POME to CBG fuel High savings possible (> 1. Mio USD/year) diesel fuel price are likely to increases savings become correspondingly more attractive CBG makes the mill independent from diesel price increases Fuel out of POME will strongly support a green and sustainable image CBG is the most attractive route for the usage of biogas

17 SEPURAN Green cartridge system The cartridge system complements the SEPURAN product port folio flexible to different pressure regulations easy membrane replacement reduced replacement costs

adapter and lug system Pre-built rack system possible.

18 Characteristics of the SEPURAN Green Cartridge System Investment for casing just once, afterwards only replacement of aacartridges necessary Easy assembly and disassembly due to low own weight of 10 kg Fast and flexible replacement of modules by reason of new adapter and lug system Pre-built rack system possible. Therefore fast connection because of elimination of piping between each and every module Fast construction of container due to easy assembly of pre-built racks Up to 200 cartridge systems in one 40 ft. container possible
