ECHO2
Rainbow Bee Eater: single purpose Australian company formed in 2009 by Ian Stanley and Peter Burgess to:
Develop and supply modular ‘biomass to energy systems’ with benchmark cost, environmental and social benefits. (ECHO2)
‘Fresh Start’ is the 1st commercial demonstration of ECHO2

ECHO2
R&D project funded since 2007 by the founders and the Australian Government
• modular biomass to electricity & heating technology, biochar ‘carbon capture’ by-product, carbon negative
• from crop, wood, food, green & animal residues
• commercially viable. Not reliant on subsidies
• automated and on demand
• very low emissions, very carbon negative

ECHO2 - the benefits1. utilises unwanted residues
2. not reliant on subsidies to build or operate
3. automated and on demand
4. uncomplicated, clean, quiet, safe
5. affordable, 2 to 8 year capital return
6. very low emissions, very carbon negative

ECHO2’s major point of difference?
Biochar AnalysisMajor strategy 2007 – 2017:
single step process to clean fuel gas
to enable viability and low cost biochar
No budget for field trials. Biochar mainly
incorporated in Ian Stanley’s wheat farm.
10 biochar analyses on prototype 2014 – 17

Stephen Joseph, NSW DPI
Prototype Summary: ~35% yield, 40% gasification
total C >85%, 3mg/kg napthalene, other PAH <LOQ
Commercial ECHO2 module: includes options for fine tuning
biochar include hot retention time, add steam, add other
chemistry. Commence testing August 2018
hot water 400 - 800 kWt
electricity 100 - 250 kWe
biochar ~ 200 kg/hr wet basis
CO2 ~ 250 kg/hr (Boiler Option)
biomass 500 - 600 kg/hr@15-25% moisturenominal 5 - 20mm, clean
footprint ~10m x 10m
ECHO2 module indicative specs
Single module. Specs are subject to biomass characteristics and an engineering study of customer requirements. ECHO2 comes with a warranty and a service agreement.
Assembling Holla Fresh’s ECHO2 Modulein SDA’s Melbourne factory
800kWt (heat), 100kWe (electricity), 250 kg/hr CO2
Van Schaik’s BioGro will supply ~500 kg/hr wood residues and receive ~250
kg/hr biochar (wb)
Expected commissioning Jul/Aug 2018
