Planet Talks at WOMADelaide 2023

WOMADelaide is best known as a glorious long weekend of music and dance from around the world. But Planet Talks also gives some special opportunities for sharing ideas with some of the world’s most inspiring thought leaders and activists who are working on key global environmental and justice issues.

Big ideas to share

For 2023 much of the focus will be on the First Nations Voice to Parliament, the Race to Netzero, Rights for Nature and Crimes Against Nature.

From Ecocide to Eden: learning from luminaries

With WOMADelaide 2022 coming up fast, it made me reflect on previous festivals.

Might it be that – in simplistic terms – there are two types of people: those who use their talents to enrich themselves, and those who use their special skills to enrich the lives of others?  My experience in media leads me to think so.

I’ve been very fortunate to interview some special people over recent years, people who have dedicated their lives to ensuring they contribute to safeguarding our planet and improving social equity, and have been guests at WOMADelaide as part of the superb Planet Talks series. Here are some of the best.

Renewable energy: solar thermal power for Port Augusta

For the past five years we’ve been tracking the superb renewable energy activism of the Port Augusta community in South Australia in their quest for a solar thermal power station.

2016 marked the end of six decades of coal-fired power generation at Port Augusta and now we finally have the announcement of a replacement that will provide dispatchable renewable energy, using CSP (Concentrated Solar Power) technology.

It’s quite brave leadership from the South Australian State Government. They’ve had to put up with a year of denigration and ridicule from the Federal Government for an ambitious transition-to-renewables program. But they’ve pushed on relentlessly, culminating in the announcement of the world’s biggest battery storage last month and now the solar with storage plant announced this week.

Finkel and the Australian climate deadlock: still not heading towards zero emissions

In their submission to the Finkel Independent Review into the Future Security of the National Electricity Market, the Climate Council made it clear that a rapid transition to net zero emissions is the priority:

To protect Australians from worsening climate impacts (eg more destructive storms, intense heatwaves and worsening bushfire conditions) and in line with our Paris Agreement commitments and carbon budget constraints, Australia needs pathways to transition as rapidly as possible away from coal, oil and gas to reach net zero emissions by 2050.

But the Finkel review has little to say about our Paris Agreement commitments. Instead it focuses on ensuring a reliable electricity grid and reducing the price of electricity.

24-hour solar on demand: an update on Solastor plans for Port Augusta

In June 2016 I reported on the launch of the Solastor 24-hour solar-on-demand project that was planned for Port Augusta in South Australia. At the time of the launch the plan was to have a pilot plant in operation by the end of the year. In November 2016 Solastor advised that they were likely to go ahead with the main project rather than doing the pilot first.

Today I checked in with Steve Hollis, CEO of Solastor, for an update on progress.

Brian:  Your Port Augusta plans outlined in your June 2016 launch were for 1,700 collector tower modules which were expected to generate 110MW in winter and 170MW in summer. Is that still the plan?

Steve:  The proposal is now to stage the project starting with a 100MW power station with 800 modules. This would do just under 50MW for 24 hours in winter and over 70MW in summer. More importantly, it will do 100MW for shorter times per day (peak hours) which is when the need is greatest.

This configuration could (would) be “cut and pasted” 5 times to give 500MW and completely replace the old to power station. Continue reading

Snowy Hydro gets a boost, but ‘seawater hydro’ could help South Australia

The federal government has announced a A$2 billion plan to expand the iconic Snowy Hydro scheme. It will carry out a feasibility study into the idea of adding “pumped hydro” storage capacity, which it says could power up to 500,000 homes. The Conversation

Hydro is one of the oldest and most mature electricity generation technologies. And pumped hydro storage – in which water is pumped uphill for later use, rather than simply flowing downriver through a hydro power station – is the dominant form of energy storage globally.

But there are limitations to how much freshwater hydro can be accessed, so it’s worth looking at what alternate approaches are available. One promising prospect is to use seawater instead of rivers. This tactic could potentially help South Australia resolve its highly publicised energy problems. Continue reading

We need to talk about undies

Yes, your undies are a very private thing. Comfort and style are immensely important, and no doubt you’ll have a strong personal preference. But we do need to talk about undies.

Do you know what nasties are riding along with your favourite undies?

Residual chemicals in clothing

It’s a significant issue in clothing, particularly for people with sensitive skin, and especially in underwear that hugs our skin so closely. So much so that Choice recommends:

wash any new clothes twice before wearing, although washing won’t remove certain types of chemicals

A chat with Sir Tim Smit – co-founder of the Eden Project

Today I had a chat with Sir Tim Smit, serial entrepreneur and co-founder of the Eden Project, ahead of his forthcoming presentation for the Planet Talks at WOMADelaide 2017.

In the prologue to his book, Eden, two sentences stand out, and they sum up the spirit of our chat: “Neither do I make any apology for being optimistic about the future. I am.”

The government is right to fund energy storage: a 100% renewable grid is within reach

In a speech to the National Press Club, Prime Minister Malcolm Turnbull declared that the key requirements for Australia’s electricity system are that it should be affordable, reliable, and able to help meet national emissions-reduction targets. He also stressed that efforts to pursue these goals should be “technology agnostic” – that is, the best solutions should be chosen on merit, regardless of whether they are based on fossil fuels, renewable energy or other technologies.

As it happens, modern wind, solar photovoltaics (PV) and off-river pumped hydro energy storage (PHES) can meet these requirements without heroic assumptions, at a cost that is competitive with fossil fuel power stations.
