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.
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 →
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.
On 7th June 2016 another important step was taken towards decarbonising the South Australian economy. Solastor Australia announced detailed plans to build a solar thermal power station at Port Augusta. Continue reading →
What was unthinkable is now unstoppable – Ban Ki Moon, UN Secretary General
His quote resonated among the many speeches that followed French President Francois Hollande’s announcement that we now have a new global understanding on climate – the legally binding Paris Agreement.
Following Copenhagen 2006, it was unthinkable 196 nations would voluntarily sign up to the world’s first global agreement to work together on climate change in good faith, with 189 lodging Intended Nationally Determined Contributions INDCs before Paris.
Yet it’s important to state plainly that the net contribution of all INDCs now in hand still commit the world to 2.7-3 of warming, so we are not out of the woods yet, but at least we are starting to take it all seriously…
It’s hard not to be overwhelmed (bouleversé, knocked over) by the intensity, complexity, sheer scale and fascination of a Conference of the Parties (COP) to the United National Framework Convention on Climate Change (UNFCCC)…
Thousands of people milling about with one common purpose in minds: how to bring our world back from the brink of catastrophic run-away climate change and create the chance for a safer future for future generations of all species.
Leaving at a more civilized hour from the youth hostel led to a slightly less civilized trip in the shuttle bus from the RER station. Queuing to get past security gave me an idea of the sheer numbers that the organisers are dealing with at the COP21 site at Le Bourget.
Hard to imagine so many meetings, conversations, information and people can fit into a single day. I guess stalwarts who’ve attended numerous COPs take it in their stride.
Today began with a short briefing for our Climate Action Network Australia (CANA) team, before we walked in to meet Leader of the Opposition, Bill Shorten in one of the formal meetings room available for delegations and side meetings.
An early start, walking with the AYCC/SEED crew to Gare du Nord under streetlights and a sinking moon, since we’d heard it might be difficult to get in today with all the leaders in town.
On the shuttle bus (navette), I met Yhro from Niger. We discussed deforestation, desertification and the unsustainable use of groundwater (nappe phreatique).
My entry into Le Bourget COP21 venue was slow while security officers took an inordinate interest in the Catholic Earthcare and Multifaith SA banners, but I was allowed through once they’d been closely scrutinized and deemed harmless.
Only once before have I attended the UN Climate Summit as a community delegate. It was at COP15 (Conference of the Parties to the UN Framework Convention on Climate Change) in Copenhagen in 2009. I met courageous people from across the world, all clearly committed to doing whatever it takes to tackle climate change for the sake of future generations, many with far fewer resources than I.
