December 5, 2018 Politicians around Australia are proposing ambitious plans to export renewable energy from Australia, using high-voltage power lines laid under the oceans.But will this work? Our research is investigating the economic and environmental case for Australia to become an Asian energy superpower.
Our recent study, which will be presented on December 11 at the UN Climate Change Conference, models electricity generation and demand – as well as the cost of augmenting and extending transmission infrastructure. We found a transmission network connecting Australia to Indonesia could help both nations achieve 100% renewable electricity by 2050. This is in line with a UN push for more global power connections. Exporting clean power from countries with strong infrastructure to burgeoning global populations may be key to reaching the Paris Agreement climate targets………… Australia’s northwest desert region has some of the world’s best solar and wind resources. An underwater high-voltage Direct Current (HVDC) link connecting Indonesia’s Java-Bali power grid to the Australian National Electricity Market grid through the Northern Territory would help both nations to achieve a 100% renewable power system by 2050. An interconnector would change the Java-Bali decarbonisation pathway dramatically. In this scenario, power generation in Java-Bali is greatly reduced due to imports; energy wasted from local wind and solar PV becomes negligible. A large amount of electricity is imported into Java-Bali from Australia, especially in the evening after the sun has set and the PV in Java-Bali stops generating. We could also take the opportunity to connect the Northern Territory to the rest of Australia’s energy market through an above-ground transmission line. Any wind and solar energy not used by Indonesia could then be fed to the national grid. Australia could then meet the bulk of its energy needs through wind power, since strategic placement of wind farms would minimise variability in generation. Our models also favoured coupling wide-scale solar power with pumped hydro facilities. Pumped hydro can store solar power during the day and send it into the grid during the evening, and thus stabilise the entire operation. Despite the high cost of building this infrastructure, our research found a 100% renewable Australasia power system could reduce wholesale electricity costs by more than 16%. Our estimates may be on the conservative side, as we assumed a constant cost for the HVDC technology but it’s likely to become cheaper in the coming decades. The model finds that the optimal configuration of the international connector from NT to Indonesia is a staggering capacity of 43.8GW with construction starting from 2030. The optimal regional transmission from NT to the east coast would have a capacity of 5.5GW. Incentives moving forward Australia is one of the most vulnerable developed countries in terms of risk from climate change. It is in our interest to promote a strong global response. Australia has inherent advantages in terms of our abundant renewable resources and geographical location in the Asia Pacific. (Of course, there are political complications to overcome.) Future research will expand the geographical scope of the current study by considering more domestic and international interconnection options to assess the economic viability of a larger Australasian super grid. The recent suggestion for electrification of Papua New Guinea and meeting the energy demands of Pacific island nations are two examples. Comparison with hydrogen exports, which might involve conversion of renewable energy into hydrogen or ammonia to allow export by ship, will also be studied. Our ultimate goal is to build a coalition of nation builders to make Australia a renewable energy exporting superpower. https://theconversation.com/making-australia-a-renewable-energy-exporting-superpower-107285 The authors are presenting their research at COP24 in partnership with GEIDCO, IEA, UN Climate Change and UN DESA. |

Zoom webinar – “Nuclear Winter: The Environmental Consequences of a Nuclear Exchange.”
April 7th at 11:30 am PST / 2:30 pm EST
Nuclear Winter: The Environmental Consequences of a Nuclear Exchange”
Join us for an informative webinar with renowned atmospheric scientist, Professor Brian Toon, as he discusses the environmental risks and global impacts of a nuclear war. Despite the potential damage caused by the blast from even small nuclear weapons, many countries continue to invest in and expand nuclear arsenals. Professor Toon will provide a scientific assessment of civilian fatalities, agricultural failures, climate concerns, and complications with food supply that would follow any international nuclear conflict. We need to plan how to prevent nuclear conflict and avoid catastrophe. Politicians and military planners must be made aware of global climate and agricultural complications that would ensue. Don’t miss this opportunity to learn from, and engage in, this vital conversation
The Road to War brings a sharp focus to why it is not in Australia’s best interest to be dragged into a war with China which will almost inevitably go nuclear very quickly. The filmmaker has interviewed some of Australia’s senior foreign policy analysts who have vast experience behind them in analysing what really is going on here as the United States rattles its sabres with China. And sets us up to be its proxy, like the poor Ukranians have been fed into the Meatgrinder. So America can remain the Top Dog. The Road to War reveals how the United States through its spy base at Pine Gap and by stationing six nuclear capable B52 bombers in the Top End (without permission from the traditional owners) is making Australia a prime nuclear target if the current war of words suddenly melts down into full scale war.
The Road to War shows the implicit connection between Carbon emissions (the US military uses a whopping 70% of America’s annual petroleum to move its armies and vast War Machine around the globe to its 800+ military bases..but under a loophole wangled at Kyoto, the US military does not have to report its C02 annual emissions). The Road to War starts screening at selected cities and regional centres in March. See the trailer end for details.
