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

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.
