Summary

Presentation Overview

Ensyn is a US, technology-based producer of renewable fuels and chemicals

Core technology is Rapid Thermal Processing (RTP™), a fast pyrolysis technology for conversion of cellulosic wood feedstocks

Commercial production of renewable chemicals and fuels since 1989

Food chemicals application of RTP developed in mid 1980’s and sold to Red Arrow Products Company (Wisconsin)

Petroleum heavy crude upgrading application of RTP developed in late 1990s and sold to Ivanhoe Energy Inc in 2005

Ensyn Corporation - Overview

Major alliance for renewable liquid fuels established with UOP Inc., a Honeywell company, in 2008

Ensyn has now developed a market-ready, conditioned RTP Renewable Heating Oil (RHO) from cellulosic wood residues

RTP transportation fuels in development

Initial projects announced in Malaysia, Alberta and Italy

Business development initiatives worldwide

Ensyn’s role: License RTP technology Participate in RTP projects

Current Focus: Renewable Liquid Fuels

RTP Background

Continuous development since 1984 Current focus: renewable fuels

Envergent Technologies: UOP/Honeywell connection

UOP/Honeywell: Engineering / performance guarantees Piggy-back PyOil technology (upgrading) Credibility Development capabilities Worldwide sales network

Ensyn: RTP technology, patents, I.P. Operating history / partnerships Proven commercial roll-out in two industries Know-how (business and technical)

UOP: FCC & RTP

RTP is close analogue to FCC (Fluid Catalytic Cracking) FCC technology is key process in gasoline production UOP has been designing FCC units since the early 1940’s – a co-inventor Licensed over 250 units – more than 50% of world-wide capacity Unit sizes from 1,500 to 200,000 BPD of capacity

Renewable Liquid Fuels

RTP PyOil Liquid Fuels Development

Crude RTP liquids have been combusted commercially for 20+ years for heating, drying or process steam

Crude RTP liquids combustion tests have been successfully carried out in numerous boiler/combustion systems up to 60 MWth (200 MMbtu/hr)

Conditioned heating oil product developed in 2010 for broader applications for heting and power generation

= RTP Renewable Heating Oil (RHO) RHO has enhanced properties compared to

ASTM-D7544-10 “Standard Specification for Pyrolysis Liquid Biofuel”

Evolution: RTP Liquid Fuels

RTP Renewable Heating Oil (RHO)

Development of a “Conditioned” heating oil for broad applications in heating and power generation= RHO

RHO can be co-fired or use alone in conventional boilers with little or no modifications

Additional uses for RHO in stationary diesels for power generation

A standardized PHO Combustion package developed to retrofit fuel oil boilers for 100% RHO use

RHO combustion emissions compare favorably with fossil fuel

Standardized RHO combustion test unit

RHO production footprint similar to other energy alternatives

GHG emission approaches zero

Assumed biomass transport distances: 200 km for logging residues 25 km for short rotation forest crops 0 km for sawmill residues
