BioEnergy in Tasmania Developments & Opportunities
Topics to be Covered (a) • 15 Tasmanian themed papers at BioEnergy 2015
• A Tasmanian Snapshot
• Tasmania’s Energy Equation – Production vs
Consumption
• Forest Residue based bioenergy is the prime
opportunity
• CEFC BioEnergy Fund very positive news
BioEnergy in Tasmania Developments & Opportunities
Topics to be Covered (b)
• Niche Opportunities
• The Key Messages ?
o The Resources are Available and
Accessible
o The Technology is Mature with
Positive Project Economics
A Tasmanian Snapshot
• Population – 500,000 - just 2% of Australia
• Land Mass – 91,000 km2 - just 1.3 % of Australia
• Forest Cover – 50% of land mass - and 50% of this is in
Conservation Areas
• Hydro Tasmania produces 25+% of Australian
Renewable’s Electricity
• “Green Branding” is an important part of State’s
identity, especially for Tourism and AgriBiz
• BioEnergy could enhance this brand
Forest Resources
• >50% of landmass
now in
conservation
reserves
• >50% of
commercial forest
is now in private
hands

Thermal Energy
Tasmanian Energy Equation
(1)
• How do we use our 100 PJ of energy each year?
• An Equal Three–Way Split
o Electricity 1/3rd
o Transport Fuels 1/3rd
o Thermal 1/3rd
• Transport Fuels – mostly imported – some
LNG/CNG/LPG
• Scope for liquid biofuels – but some commercial
barriers and technical to uptake
Tasmanian Energy Equation
(2)
• Thermal Energy Sector - Wood, Coal &
Gas
o BioEnergy offering Growth and
Substitution Opportunities
o CHP- CoGen – not Grid Electricity
• For coal & gas, important to distinguish
energy applications from other uses e.g.
cement, metallurgical and chemical
manufacturing,
Forest Residues Studies
(1)
• Looking for “value-add” opportunities – beyond the
export woodchip market
• Indufor Study – commissioned in 2013 - part of
Tasmanian Forests Agreement (TFA)
• Enecon – subcontracted to do BioEnergy component of
study
• Bioenergy possibilities recognised as a key sector for
investigation
Forest Residues Studies
(2)
• Indufor Report close to finalisation
• Findings to be reported at BioEnergy 2015
o CHP & Export Wood Pellet markets identified
as priorities
o Positive Economics are indicated
o “Drop-In” biofuels a longer term possibility
• “Southern Residues” EOI Process in progress –
driven by export logistics constraints
• Programs of support will emerge for BioEnergy
Initiatives
• Small to medium scale – using < 10,000 tpa fuel per
enterprise
• Briquetting, chipping or hogging of residues – for
industrial process heat in boilers
• Use the 5% of “pin-chips” screened from export chips
• Market for Wood Pellets for domestic heating on
expansion path
• Small-scale ( <100 kw ) boilers for hot water and space
heating in commercial premises – Regional Hospitals,
Swimming Pools and SMEs
Niche BioEnergy Opportunities (1)
• Agricultural processing residues and woody
weeds
• Biochar may enhance pastures being converted
by irrigation
• Biochar emerging with a remedial role for dairy
effluent
• Special chars – activated carbon, premium BBQ
fuels etc.
• Projects attracting community support and
engagement
Niche BioEnergy Opportunities (2)
Carbon Neutral Bricks
Carbon Neutral Bricks from Biomass (1)
• Austral Bricks – Longford
• 1.5 million bricks per year
• Australia’s first “Carbon Neutral” bricks
• Certified by Australian Government
• Supply chain showing wood residues are
from sustainable sources
Carbon Neutral Bricks from Biomass (2)
• 10,000 tpa of hardwood sawmill residues
• Residue is milled and dried to dust
• Wood provides 90% of energy needs
• Kiln runs at 1,200 degrees Celsius
• Gas used for “makeup” heat at cool front-end of kiln
• Gas use is 10% but represents 30% of energy bill
• Bricks being exported to Japan, Korea and New Zealand

Waste Water Treatment Plants (WWTP)
& Anaerobic Digesters (AD)
(1)
• TasWater – Tasmania’s Water & Sewerage Authority -
needs to protect its assets and guarantee performance
• EPA monitors TasWater’s outfall – impact of “load” from
upstream
• TasWater lifting “Trade Waste Charges” (TWC) to cover
capital and operating costs
• TasWater offerring TWC “holidays” if industries
improve their on-site pre-treatment plants
• These holidays from the notional increase in TWC
provide an economic incentive for industries to install
new plant
Waste Water Treatment Plants (WWTP)
& Anaerobic Digesters (AD)
(2)
• Tasmanian has large food processing sector e.g.
dairy, meat, breweries
• Anaerobic Digesters becoming key component of
WWTPs
• Biogas from ADs is supplementing energy bought
in for processing
• Creating Value from problematic and costly waste
streams
Cascade Brewery
Biogas from Effluent (3)
• All waste water is captured and retreated
• Project was driven by strict limits on discharges and
faced with high “Trade Waste” disposal costs
• Major Investment in a Waterleau treatment facility
• Anaerobic digestion of waste stream now producing
biogas
• Displacing 20% of their natural gas usage & major
environmental benefits
• “Clean Green” branding benefits. Lessens load on Infra
Eco-Industrial Parks
(3)
• Clustering of Energy Users & Biomass Residue Sources
o Hubs with Logistics and services
• CHP/CoGen using Biomass
o +ve Economics compared to Natural Gas
• Steam for Industrial Processes & Electricity within Park
• Centralised Energy Provision on “over the fence” basis
using BOOT model
• Optimise & Balance CHP Load among users & providers
of energy
