1 Nexterra s Future with RDF Gasification and Syngas Technologies Conference Vancouver BC October 2016

2 Business Overview Business Description Founded in 2003, Built nine plants Two plants under construction Systems operating on hog fuel, forest residuals, and construction and demolition (C&D) waste wood North American Projects Built Under Construction Commissioning Vancouver, BC UBC Victoria, BC Dockside Green New Westminster, BC Kruger Prince George, BC UNBC Heffley Creek, BC Tolko Plywood Mill Battle Creek, MI VA Battle Creek Columbia, SC USC Oak Ridge, TN Oak Ridge Nat l Lab UK Projects Built Under Construction Commissioning Tyseley, UK Birmingham Bio Power Northamptonshire, UK Welland Waste Wood Plymouth, UK Dartmoor Bio Power 2

3 Robust Roadmap and a History of Firsts Key Milestones 2015 First Project with Ownership 2014 First 20 Gasifier Operational 2013 First Bankable, Power to the Grid Project 2012 z First CHP Plant with IC Engine 2007 First 16 Gasifier at Institutional Site 2006 First Commercial Plant (14 Gasifier) 2004 First Plant, Pilot Plant (8 Gasifier) 3

4 Current Market Focus - UK Market Drivers Nexterra qualifies for ACT Landfill tax High power prices Plentiful feedstock Nexterra track record Nexterra right sized capacity Initial Market Success Partnerships with developers, EPCs and investors Closed three waste wood projects More to come 4

5 Industry Trends A Drive to RDF Feedstocks RDF is the next feedstock for Nexterra Key drivers promoting gasification of RDF using Nexterra technology: Growth in circular economy making incineration and landfilling less desirable Transition towards community scale plants (volumes of waste decreasing) Rising tipping fees for waste Tightening air emission guidelines Growing need for baseload renewable power Nexterra believes that with current UK tipping fees, RDF projects can be viable without subsidy 5

6 Technical Evaluation of RDF vs. Waste Wood Class A C Waste Wood RDF Consistency Homogenous Heterogeneous Components Wood Plastic, organics, fabric, paper, wood etc. Moisture Content 15 30% 10 40% Average NCV (MJ/kg) Chlorine % Up to 1.8% Sulfur % Up to 0.9% Ash 0 5% 5 30% 6

7 Key Technical Questions with RDF Objective is to process RDF in Nexterra gasifier with few changes to proven gasification platform. Key technology questions for RDF gasification include: Can feed system deliver RDF into gasifier? Will critical pile geometry be maintained? Will ash clinker and plug gasifier? Can system handle contaminants in feedstock (eg chlorine)? Can we meet UK/Euro emission regulations (IED)? Any restraint on design capacity? Only way to answer questions is with testing and demonstration 7

8 Nexterra Product Development Centre (PDC) Nexterra PDC Commissioned in 2004 ~16,000 hours of operation Waste wood, virgin wood and chips Plant Modes of Operation Indirect Fired (ie. UK configuration) Direct Fired (Lime Kiln or Boiler burners) Gas Cleanup (engine or remote burners) 8

9 Testing Program Phase 1 - Feed Table Testing (2 Weeks) - Complete Successful transport and feeding of RDF fuel Good cold pile formation Phase 2 Gasification Trials (2 Weeks) Oct 17 Successful gasification and ash flow Target system output (PAHRR) Verify emissions (without abatement) Phase 3 Optimization (2 4 Weeks) Process Optimization Stakeholder monitoring, investigation and evaluation Feed Table Test Phase 4 Reporting and Commercial Analysis 3rd party emission test results Recommendations for commercial plant design 9

10 Commercialization Plan Extensive 3rd party validation of RDF trials Focus on feedstock preparation required to meet gasification system specification Build first system with dual fuel capability. Finance on waste wood. Waste wood guarantees. Focus on UK market with existing partners and supply chain. Lower risk. Expand later Replicate with partners 10

12 RDF Testing Feeding RDF to full scale horizontal feed screw 12

13 RDF Testing Feeding RDF to full scale horizontal feed screw 13 Private & 13

14 RDF Test Results RDF emerging from top of full scale cone 14 Private & 14

15 RDF Test Results RDF forming correct pile shape for optimum gasification 15 Private & 15

16 RDF Testing to do Gasification trials on now, completing end of October So far so good: feeding, gasification, and ash removal More run time and analysis required Trials being witnessed by three engineering firms, two EPC contractors, others Nexterra expects clear validation of its technology on RDF 16 Private & 16

17 Summary Compelling business case to prove out technology on RDF Physical and chemical properties are similar to waste wood Nexterra systems operate on waste wood Test results promising for RDF Ready to build first dual fuel plant 17 Private & 17
