Renewable energy news
I’m reminded of my school days when our German teacher on the last day of term used to read us tales of Baron Münchhausen, who on one occasion jumped on his horse and rode off madly in all directions. There is so much going on, fully covered at RenewEconomy, so it is difficult to select the most significant. I’ll try a couple of themes, and include some AFR coverage, which is trying to keep business informed.
The South Australian tender for 100MW grid-scale storage has received 90 expressions of interest from 10 countries, demonstrating an established global industry. Continue reading Climate clippings 203
When Elon Musk dramatically promised to build a grid-scale battery in South Australia, the media was enthralled. Share traders and a string of Australian fund managers smirked. They’d seen it all before, and were shorting him in the market.
In that very week he was in the market with plans to raise $US1.15 billion in equity and convertible notes. I understand also that Tesla has gone strangely quiet about SA since then. Continue reading Climate clippings 201
The Murdoch media continues to lay the blame on renewables, a notion specifically rejected by AEMO, leading to a Twitter battle between SA minister Tom Koutsantonis and The Australian’s Adelaide bureau chief, Michael Owen.

Malcolm Turnbull has now, for reasons best known to himself, elevated “energy crisis” to a “national security” issue. Ben Potter puts the situation well:
A decade of fighting over renewable energy, carbon prices and fossil fuels has left Australia with some of the world’s dirtiest and costliest energy – a bitter yield from historical abundance.
Three years ago, manufacturers began complaining they couldn’t get gas, and 18 months ago the South Australian grid started to wobble.
Now, electricity and gas prices across the eastern states are two to three times their levels only a couple of years ago.
Gas exporters overcommitted to foreign buyers; the federal government mismanaged renewable energy and the regulatory apparatus – and politicians responsible for it – are frozen in the headlights.

The innovative LiquidPiston engine, mentioned by BilB, is targetting a global market worth $460 billion. It has a power to weight ratio more than ten times better than a regular engine:
The big bruiser on the left puts out 35 HP, the one on the right 40 HP. Continue reading Climate clippings 198
1. China drives electric vehicles boom
An AFR article about investors piling into lithium and graphite mining stocks tells a tale. With our focus on Tesla we are missing the story of China.

David Leitch’s article Battery storage: Bad advice about costs is fooling Australian governments reviews two American reports on grid-scale battery storage in the states of Texas and Massachusetts. He says the reports:
are detailed, professionally modelled and far more forward looking and sophisticated than anything so far produced by traditional Australian electricity consultants such as Jacobs, Frontier, IES, Ernst & Young or ACIL Allen.
Leitch, the principal of ITK says in their view:
Australia is being held back, in part, because consultants in Australia provide advice to federal and state governments based on expensive models that are basically out of date. The models don’t, and in fact can’t, take an integrated (whole of system) view.

Bloomberg is warning that the multi-trillion-dollar ‘big crash’ in oil investments could start as soon as 2023. However, the smart money is bound to move earlier. Here’s the progress of electric car sales:

In what is called ‘attribution science’ climate scientists are getting better at analysing how much climate change has influenced particular extreme weather events.
In short, it is no longer a question of weather there is an influence, rather how much.
It would be useful to know, for example, whether the kind of storm that hit South Australia is still a once in 50 years event. Continue reading Climate clippings 185
The latest Morgan Stanley report is bullish about the growth of battery storage in the Australian market. They think we’ll have 6.6GWh of battery storage in Australia by 2020, which is what the Australian Energy Market Operator last week predicted for 2035. Continue reading Climate clippings 176
The Powerwall is a 7 kilowatt hour (kWh) lithium-ion-battery system that stores electricity generated from rooftop solar panels (or PV panels) during the day so that electricity can be used at night during the peak-usage times.
Most existing solar panel owners will need to obtain a new inverter to connect with the grid. Continue reading Climate clippings 163
