Putting bioenergy on the map

ONE of the world’s most progressive renewable energy states is looking to expand its bioenergy industry as it strives to use green energy to supply half of its electricity needs by 2025.

The South Australian Government has revealed its bioenergy roadmap to help it reach its goals, which also include carbon neutrality by 2050 and for Adelaide to be the world’s first carbon neutral city.

Wind (34 per cent) and solar (7 per cent) provided 41 per cent of South Australia’s power in 2014/15.

On a per capita basis, South Australia’s performance is internationally significant.

Current levels of market penetration in wind in South Australia, as a proportion of total electricity generation, are competitive with leading international jurisdictions such as Denmark and Portugal.

South Australia’s levels of solar installed, on a per person basis, are comparable with other high solar penetration countries in Europe, such as Germany, Italy and Belgium.

The roadmap’s first stage will outline the state’s bioenergy potential, including an analysis of conversion technologies, local demand, types and quantities of feedstock, which may include new energy crops. This stage will identify two to three localised areas for further investigation.

Stage two specifically assesses these localised areas through convening community and industry groups to investigate potential collaboration in providing feedstocks, utilising energy outputs and assessing the feasibility of options. Stage three is to build specific projects.

Bioenergy can be produced from organic matter, derived from plants, animals or manufactured food waste, known as biomass or biofuel feedstocks. About 10 bioenergy plants are already operating in South Australia.

South Australian Mineral Resources and Energy Minister Tom Koutsantonis said bioenergy could play a significant role in coming years by supplying a localised energy source in low input, peak demand periods.

“Biomass resources are a sustainable and environmentally-friendly feedstock that will contribute significantly to a diversifying our energy sources,” Koutsantonis said.

“Electricity, transportation fuels, chemicals and materials currently produced from petroleum and natural gas could instead be produced from these biomass resources.

“As the costs of traditional energy such as electricity and gas continue to rise, we have the potential to make greater use of existing and new feedstock and allow bioenergy to contribute to the state’s low carbon future.”



South Australia has also become the first Australian state to sign up to an international agreement to limit global warming to less than two degrees Celsius.

The ‘Under2MOU’ agreement was signed by eight states, regions and cities during a ceremony hosted by Governor of California Jerry Brown at the US Ambassador’s residence on December 6 as part of the Paris Climate Change Conference.

Eighty jurisdictions are now signatories to the Under2MOU, hailing from 22 countries, representing 614 million people and more than $18.6 trillion in GDP – a quarter of the world’s economy.

South Australian Premier Jay Weatherill said the agreement was recently described as a potential “game changer” by UN Secretary General Ban Ki-moon.

“While national Governments are working towards an agreement on limiting global emissions, it will be the cities and states that will need to do the heavy lifting,” Weatherill said.

    Geeez, I hope everyone understands that this does not mean growing soybean for oil to substitute diesel! It means using the degraded soy oil after it has spent a week in the deep fryer at the local fish’n’chips and even the soap makers won’t touch it. The bulk of the biomass will be wood waste from plantations (only about 30-40% of a tree ends up in wood product (think twigs/branches/knots/rots), straw from wheat harvest (retaining enough to control wind and evaporation), builders off cuts, and so on. Pyrolyse the biomass and you have a substitute for jet fuel or diesel.
    Promoters of these schemes get so far and then find out how little biomass is actually available, mainly of course because photosynthesis is only 0.1% efficient and only 0.1% of fixed carbon stays around until harvest. Compare to solar panels at 20% efficiency or feeding a pumped hydro storage scheme (80% cycle efficiency) for overall 16% efficiency.
