Bioenergy Australia A government-industry-research information and networking forum set up in 1997. Creating an awareness and understanding of biomass as a sustainable resource for energy and bio-products. ~ 50 member organisations Government (Fed and States) Research Fuel Producers and Suppliers Project Developers Forestry and Agricultural organisations Waste Management Consultancies Industry Bodies (APL and AFPA). www.bioenergyaustralia.org
ARENA Measure: Knowledge Sharing and Promoting Australia s Participation in IEA Bioenergy Tasks The project focusses on the co-ordination and promotion of Australia s participation in five IEA Bioenergy Tasks. Task 37 Energy from Biogas Task 38 Climate Change Effects of Biomass & Bioenergy Systems Task 39 Commercialising Liquid Biofuels from Biomass Task 42 Biorefining in a Future Bioeconomy Task 43 Biomass Feedstocks for Energy Markets.
Global production in 2014 433 TWh bioelectricity 94 billion liters bioethanol 29.7 billion liters biodiesel

Advanced Biofuels Two Main Technology Platforms Biochemical: conversion of cellulose and hemicellulose to sugars and fermentation to alcohol fuels Thermochemical: gasification to syngas and synthesis to fuels. Advanced biofuels aim to reduce costs, broaden range of feedstocks and hence allow increase in scale. Bioenergy Australia

Some Barriers to Bioenergy Implementation Low cost of fossil fuel (coals for electricity, oil for transport) Better recognition of bioenergy by policy makers and shapers at intersection of several policy areas Concerns about using native forest biomass for fuel. Broader sustainability issues e.g. food vs. fuel and water Economics of fuel procurement. Lack of bioheat incentives Need long term regulatory stability for projects with a life greater than 25 years.
