2 Name: Company: Title: Qualification: Steve Rowntree Greenlane Technologies Managing Director, BE (Mech, Hons) Experience: 20+ years with Greenlane Biogas, in a variety of roles including leading design, sales and projects teams in delivering innovative and leading edge biogas upgrading and gas conditioning solutions for global markets. NZ developed technology & IP exported across the globe. 2

3 This Presentation will look at: Pollution & Possible Solutions Biogas & Its Uses Greenlane Biogas Upgrading Technology Case Studies Opportunities in New Zealand Conclusions Questions 3

4 We are facing a pollution & greenhouse gas crisis! Polluted rivers and waterways Contaminated ground & drinking water Nutrient run off leads to algal blooms Air pollution & uncontrolled release of CH 4 (21x worse than CO 2 ) into the air which contributes to global warming 4

5 Utilisation of Organic Waste to make biogas: Reduced air emissions of volatile organic compounds, ammonia, and methane Creation of organic fertilisers & composts Clean rivers & lakes, abundant marine life Quality ground & drinking water Reduction in Fossil Fuel use Connecting Biogas sources to fossil fuel users to utilise our waste efficiently. Improving our waste handling and challenging ourselves in NZ to practice what we preach. Clean & Green 5

6 Biogas is one of the key renewable sources of energy next to solar and wind. It utilises the natural energy present in organic matter. Biogas can be produced in an environmentally responsible and CO 2 neutral way from many organic waste sources such as: Municipal solid waste & Landfill Waste Water Treatment Plants Separated Food Waste Animal manure & farm/dairy waste Energy crops/agriculture 6

7 Biogas can be used in its raw form or upgraded to Biomethane whereby it becomes a valuable commodity displacing fossil fuels: Boilers A high efficiency (98%) way of utilising the energy, great for regions that have circulated domestic hot water Power Generation A lower efficiency way of generating something out of a waste stream. Permitting and grid connectivity issues may exist. Upgraded Biomethane Removal of bulk CO 2 & H 2 S leaves a methane rich product gas known as Biomethane. Biomethane is high value product, that can be stored or utilised in a number of different ways. Effective use enhances the environment. 7

9 Boilers or Power Generation Captured Manure/Farm/ Organic Waste Biogas Production Anaerobic Digestion Upgrading biogas to clean biomethane Pipeline Gas, Domestic Bottling or CNG Refuelling Stations CO 2 release to atmosphere CO 2 release to atmosphere Unlike fossil fuels, biogas comes from processes that have previously consumed CO 2, resulting in a naturally balanced cycle. The Greenlane process uses feedstock available at the start of the value chain. 9

10 1. Biogas compressed & fed to scrubber to remove impurities 2. Biogas showered with water, CH4 passes through and impurities trapped in water 3. Methane not recovered in scrubbing stage gets flashed off and recovered 4. Clean gas purified for customer delivery 10

11 Simple & Robust Water, no chemicals Reliable & high availability Removes H 2 S & siloxanes Proven Approaching 100 installations Upgrade biogas from landfills, agricultural waste sites & WWTP Cost-Effective Modular, standardized units Energy efficient Low capital & operating costs High Purity Biomethane > 97-98% biomethane < 1% methane slip (loss) Vehicle fuel or pipeline injection 11

12 Our product range draws back to our Kiwi heritage. We have NZ natives planted across the globe! Kanuka Rimu Matai Totara/Totara+ 50 to 300 Nm 3 /hr 250 to 800 Nm 3 /hr 400 to 1200 Nm 3 /hr 650 to 2000 Nm 3 /hr 1000 to 2500 Nm 3 /hr 12

13 Terrebone, Canada 13

14 Terrebone, Canada System 7x Totara+ Capacity Application 16,000 Nm3/hr Landfill Biomethane Use Installed 2014 Trans Canada pipeline injection Overview Largest Biomethane plant in the world. 7x 2 stage Rotary Vane Compression Packages. Greenlane provided all process equipment and integration: -Blower -VPSA -Regenerative thermal oxidizer -3x 50% Booster Compressors -Flare 14

15 Güstrow, Germany 15

16 Güstrow, Germany The largest Anaerobic Digestion to biomethane project in the world Injecting biomethane into the German natural gas since early Over 10,000 Nm 3 /hr (6000 scfm) of biogas processing capacity Digester feedstock is corn from local farmers Lowest operating costs in the market 16

17 Abbotsford, Canada First AD to biomethane project in Canada Installed June 2010 with 800 Nm 3 /hr capacity Digester feedstocks include dairy, hog, poultry, vegetable waste from nearby farms Biomethane fed to FortisBC (Terasen) grid, with biomethane quality measurement by Greenlane and FortisBC The overall system is fully automated with a remote monitoring package to minimize the time requirement for on-site attention 17

18 Redvale, New Zealand A chance to promote biogas in NZ through a small demonstration project, upgrading LFG to run a duel fuel collection truck. Imagine the truck collecting your rubbish being fuelled by the rubbish collected the month before! Showcased a collaborative effort from: Greenlane Manuka Biogas Upgrading plant NIWA CNG Compressor Dieselgas Dual fuel collection truck Transpacific Site & Landfill gas supply Typical gas compositions achieved are below. Component Raw LFG Biomethane Methane (CH 4 ) 56% 82.1% Carbon Dioxide (CO 2 ) 36% 2.7% Oxygen (O 2 ) 1.5% 2.9% Nitrogen / Other (N 2 /VOC) 6.5% 12.3% Hydrogen Sulphide (H 2 S) 270 ppm 1 ppm 18

19 Redvale, New Zealand Redvale is 9 th largest gas field in NZ (1.) Potential for >50 million LDE), on a yearly basis, if the landfill gas was all upgraded to biomethane. The demo project saved 12,000 l/yr, diesel and reduced carbon emissions by 290 tonnes/yr. Gas production at Redvale expected to peak in Ministry of Economic Development Placement based on 2009 gas field output 19

20 Landfill to CNG.Redvale and other NZ sites Being low users of electricity, upgrading landfill gas to vehicle fuel and running collection trucks and perhaps city buses (displacing current diesel costs) Dairy Factories Possibility for CNG on milk tankers doing regular circular runs to farms Auckland Council initiative for food waste separation Wouldn t it be great if we could utilise the biogas generated to run the cities buses to reduce air pollution and be a greener city. Cities such as Hamilton with existing CNG bus fleet Is there a local source of biogas that could be used to generate locally grown fuel rather than natural gas (fossil). Talk to Greenlane to discuss your waste handling and opportunities with biogas 20

21 Effective utilisation of Biogas will give: significant reduction in greenhouse gas emissions better waste handling and treatment reducing water and air pollution Creation of useful by-products such as fertiliser, compost and animal bedding Displacement of fossil fuels further reducing CO 2 emissions & pollution In NZ, utilising our waste and generated biogas effectively can make a significant impact on protecting the environment and providing a sustainable circular solution for the future. 21
