IEA Bioenergy Task 44:”Flexible bioenergy and system integration”

• operate as a key element in the coupling of different energy sectors;

• provide low-carbon energy to complement wind and solar (residual load and grid stabilisation);

• store electricity chemically into fuels to enable more efficient use of wind and solar;

• provide sustainable fuels for sectors where other decarbonisation options are not available or exceedingly expensive;

• provide high temperature heat to industry, and low temperature heat for buildings (and sanitary water) during dark and cold seasons;

• coproduce heat, electricity, fuels and other products in a single high-efficiency processing plant.

Case Study: Transforming Agriculture through Anaerobic Digestion

Richard Gorman - Kalfresh Pty Ltd

Presented to Bioenergy Australia Webinar Series – 10 July 2020

v

DIVERSIFICATION & REGIONAL SUSTAINABILITYThe Precinct will create a hub for value-added food & beverage production in the Scenic Rim.

Access to rural industrial land where the raw ingredientsgrow

Faster turnaround from paddock to plate Delivers Renewable Energy to precinct tenants Reduced Food Miles Operational Efficiencies Agricultural Diversification Greater Demand for Australian-grown produce Export Opportunities

Kalfresh Case Study: Transforming Agriculture through Anaerobic Digestion

v

WONKY CARROTS & UNRELIABLE POWER Australian horticulture faces some big challenges• Operating costs are rising. Margins are shrinking• We must do more with less• Food Waste due to out-of-spec produce - a growing and real problem• Consumer Trend is for prepared, ready-to-eat vegetable products• Processed vegetables require sophisticated machinery + stable power

HOW CAN WE FARM SMARTER?This question led us to Anaerobic Digesters in Europe and America.

Ticks many Boxes Vegetable Waste management Reliable baseload power Energy crop revenue for farms Digestate to replace synthetic fertiliser

THE CHALLENGES FACING HORTICULTURE


v

WHY CO-DIGESTION?The Bioenergy Facility is pivotal to the commercial success of the Agricultural Precinct

Delivers renewable energy to Agricultural Precinct tenants

Low-cost Grid Connection in Regional Area

Power that’s independent of geography & season

Baseload Power 24/7

Waste Diversion: Urban & Agricultural

Multiple Revenue Streams

Waste Receival + Fertiliser

Reliable Supply at peak times

Scaleable as Precinct is fully developed

RENEWABLE ENERGY

v

Consumes excess CHP Thermal Heat

Captures beneficial bacteria

Custom, crop-specific pellets

Simple to dose

Low-impact, reduces ground compaction & wages in

field

Beneficial bacteria works 3 to 4 times better when

delivered via pellets

Multiplier Effect: Allows stabilised bacteria to colonise

the soil to further enhance carbon

Allows farmers to provide crops with more nutrition than

they could normally afford

Creates opportunity for regional jobs & investment

AGRICULTURAL INNOVATIONWhile what we are proposing is happening overseas, it is new for Australian agriculture.

v

Co-Digestion & Fertiliser Model unique in Australia

Diverts urban & agricultural waste

Closes the Loop of waste streams

Generates affordable renewable power

Adds Value to digestate, an AD waste product

Utilises Heat output

Marries bacteria with its food source

Efficient, low-impact delivery

Bespoke organic nutrient

COMMERCIAL INNOVATION


The Digestor / Fertiliser Model is attractive as it delivers multiple benefits to rural & regional Australia.

v

The Carbon Abatement potential of our proposal delivers innovation to the Australian renewable energy landscape.

Opportunity for significant reduction in Greenhouse Gas Emissions

Co-digestion removes grease trap waste from urban environment

Bio-fertiliser replaces synthetic fertilisers made using fossil fuels

Carbon capture in soil + above ground biomass

Reverses soil degradation

Returns farmland to a healthy, productive state

Decarbonises food manufacturing

CARBON ABATEMENT

The Danish waste model

- Following the principles in the waste hierarchy

- State tax on waste:• Tax on landfill: $ 70 per tonne (2020)• Tax on incineration: $ 49 per tonne (2020)• Tax on recycling: No tax

- A combination of administrative measures and regulations as well as economic measures such as taxes and duties.

Flexible bioenergy solutions for increasing the carbon conversion efficiency of

anaerobic digestion

Ian Rowe10 July 2020

Office of Energy Efficiency and Renewable Energy

Bioenergy Technologies Office

• Develop ways to use our abundant renewable biomass resources to make biofuels and biobased products which are classically derived from petroleum

• Feedstocks for making biofuels and bioproducts:• Non-food sources of biomass, such as algae, agricultural

residues and forestry trimmings, and energy crops like switchgrass and miscanthus.

• Wet wastes, such as biosolids, fats, oils and grease and food and animal waste

• Municipal solid wastes• Waste gases, such as CO2

Expanding view of renewable carbon resources

Bioenergy Technologies Office structure

• $240M in FY20 funding• Funds applied R&D work at DOE national labs

and in the private sector/academia

• Divided into 5 Technology Programs:• Feedstock Supply and Logistics• Advanced Algal Systems• Conversion• Demonstration and Market Transformation• Analysis and Sustainability

Two major innovations:

1) An advanced wet oxidation/steam explosion pretreatment of undigested solids from a primary AD to increase carbon conversion efficiency

2) An immobilized bioreactor for biomethanation of the CO2 within the biogas stream

End goal: 70%+ of carbon converted to CH4

AD providing bioflexibility

Novel and Viable Technologies for Converting Wet Organic Waste Streams to High Value Products – SUNY Albany (Yanna Liang, PI)

Three major innovations:

1) Thermal hydrolysis + sonication of waste stream to increase lability

2) Liquid/Liquid extraction of AD reactor to remove VFAs prior to methanogenesis

3) MFC + MES system to convert CO2 to additional VFA

End goal: 50% increase of carbon conversion efficiency

Biogas upgrading via biomethanation for energy storage
