Renewable Industry’s Giant Battery Claims Unplugged

South Australia’s head count mounts …

***

With Californian carpet-bagger, Elon Musk swooping on South Australia to scoop up as much as he can of the $550 million its hapless Labor government is about to squander on non-fixes for its self-inflicted wind power disaster, it’s time to put pen to paper to work out just how risible is SA’s plan to rely on giant batteries. Here’s Paul Miskelly and Tom Quirk crunching the numbers.

South Australia – a Renewable State?
Watts up with that?

With $90 billion spent on batteries and 4,000 MW of more wind farms, South Australia could be a totally renewable state, at least for electricity.

South Australia along with one or two other states has been described by Al Gore as the canary in the coal mine for climate change and renewable energy. This interesting comparison was rewarded by South Australia putting the canary in the dark as there was no coal. But it would be interesting to see what the electricity supply of South Australia might be like with zero CO2 emissions as is the fond wish of many and even of learned societies.

There are many combinations of renewables that could be considered with wind, solar, biomass, pumped storage and various storage technologies. The following is the simplest, combining wind farms and batteries.

The starting point for this analysis is the dominance of wind power in South Australia. To expand this renewable source we must add battery storage as there are no present alternatives. The present 1575 MW of wind farms meets some 35% of demand and expanding this to give an average 100% of supply. We must store the surplus and use that when the wind falls away. The performance of the present demand and wind farms supply is sampled from AEMO data for 3 January to 31 March 2016.

So wind farm output is increased by 358% to 5644 MW, an additional 4069 MW of wind farms, so that the average over 3 months equals the average demand. This is presented in Figure 1 and shows periods of surplus and deficit of supply.

The total surplus is equal to the total deficit and the detail is shown in Figure 2. There are periods for example 17 to 24 January 2016 where the average deficit is 750 MW for 168 hours, a total of 125,000 MWh. This is a measure of the energy storage that is needed from the surplus energy of the period 13 to 17 January. For the year 2016 the demand in South Australia was 14,400 GWh so the storage need is of the order of 1% of the demand for the year.

Figure 2: Variations of surplus and deficit from wind farm supply compared to demand for January to March 2016

The variations in storage needs are shown in Figure 3. The maximum storage need is defined as the value necessary to satisfy demand at all times. This is a value of 270 GWh (270,000 MWh) for the period analysed. This is 2% of the annual demand for electricity in South Australia.

The challenge is to identify storage technology for some 300 GWh of supply. The base case is to calculate the amount and cost of lead acid batteries to satisfy this need.

A very thorough summary of storage technologies is to be found in Sustainable Energy[1]. Figure 4 is a summary of the storage technology power and energy density capabilities. The range of batteries extends from lead acid to lithium-ion and beyond. For this analysis the energy densities are the mid range values for lead acid and lithium-ion.

On the bottom far right of the figure, the hydrocarbons (fossil fuels) show energy densities of a factor of ten greater than the batteries considered here.

Figure 4: Scatter (Ragone) plot of power and energy density for storage technologies from page 400 of reference 1.

***

So for the lead acid batteries adopting a value of 40 Wh/kg for 300 GWh of storage requires 7,500,000 tonnes of lead acid batteries. For higher energy density lithium-ion batteries have an energy density of 140 Wh/kg so only 2,100,000 tonnes would be needed.

But this could be realized, but at what cost? Estimates of lead acid battery costs are around $0.20 per Wh while lithium-ion batteries vary from $0.50 to $0.90 per Wh. The Power Wall 2 lithium-ion battery from Tesla is A$8,000 for 14 kWh but this is a retail price of $0.57 per Wh. The wholesale bulk price could be as low as $0.30 per Wh with better performance than the lead acid battery in discharge rate and lifetime.

Willem Post has a detailed article on energy storage in Germany. His base case is lead acid batteries with massive, bulk energy storage. The cost per Wh is $0.32.

So the battery storage is some $60 to $90 billion to store the surplus energy from 4,000 MW of new wind farms with substantial running costs due to battery lifetime and erratic discharges.

This analysis outlines the storage required to address wind’s inherent intermittency. It does not address the requirements, presently unaddressed by wind energy technology, of grid stability and control, which is the need for the provision of synchronous inertia to protect grid stability. Should the battery route be chosen to address this requirement, such provision may indeed require more battery storage.

Of course South Australia could close all the gas fueled power stations and build massive interconnectors to the other states and then blame them for CO2 emissions. Perhaps that is why the South Australian government talks of nationalizing the power stations/

The giant battery myth just keeps on truckin’.

Renewables wouldn’t exist without massive subsidies and/or Soviet era government mandates and that same observation follows for subsidy-soaked power storage. None of it makes economic sense: pull the plug on the subsidies and the firms behind them disappear like snowflakes in summer. And the business models of some are so shaky that they collapse even when the subsidies are still flowing.

Subsidized Company, Supplying Subsidized Industry (Which Is Based On Subsidized Junk Science) Files For Bankruptcy
No Tricks Zone

11 March 2017

I had to shake my head when reading the recently published Fox News report: Another taxpayer-funded energy company files for bankruptcy.

According to Fox News, Pennsylvania-based Aquion Energy had received “a $5.2 million stimulus-tied grant” (not a loan) from the U.S. federal government and that the company had once been “touted as a rising star in the energy storage business”. It even attracted “an investment from Microsoft founder Bill Gates“.

On Wednesday Aquion Energy filed for Chapter 11 bankruptcy.

“North American Company of the Year”

Fox News adds:

In January (2017), the company was named ‘the North American Company of the Year Award’ at the annual Cleantech Forum in San Francisco…”

This is a classic example of how a house of cards gets built and begins to collapse. It should remind us of what can happen whenever bureaucrats and politicians get so caught up in a pie-in-the-sky idea that they literally become deaf to technical, scientific and economic reason.

Multi-tiered subsidy debacle

There was certainly no lack of warnings from skeptics that renewable energies (mainly sun and wind) were fraught with daunting technical and economic obstacles, and that the technology for overcoming these obstacles still remained decades out into the future.

But green energy proponents wanted to hear none of it, and so embarked on a blind and reckless money give-away of the sort never seen before. Already trillions have been earmarked worldwide — one trillion in Germany alone.

Today the green energy subsidy folly has since made its way down through multiple supply tiers as the government funds tens of billions of dollars to prop up the junk science that tells us us we need the green energies, which in turn also receive hundreds of billions in subsidies. This in turn has led to billions in subsidies made to companies claiming to have the technologies for overcoming the technical hurdles that the rest of us had long warned about.

What’s next? As expected these companies are now folding. It was a scam all along, as they were never as close to solutions as they led many of us to believe. Now the government will have to subsidize the many workers who are losing their jobs, at least for awhile, as scheme implodes on itself. What a folly.

Driven by rampant cronyism

Naturally almost everyone supports funding for the development of new energy technologies, but there is a huge difference between pitch-forking tax dollars, by the billions, into a huge crony feeding trough, and wisely and strategically allocating precious funds to the right places.

Unfortunately the green industry has been one driven by cronyism, and not technical or scientific merit — and certainly not economics. It has been a huge bonanza for very few at the great expense of the common good. The hundreds and hundreds of billions wasted would have been far better invested elsewhere.

The storage solutions come from the past, not the future

When it comes to efficient energy storage, putting a man on the moon is in fact easy compared to finding a new way that stores energy even a fraction as well as a chunk of coal, a bottle of gas, or can of petroleum does. In fact we find the storage solution millions of years in the past in the form of fossil fuels, and not the shady, over-hyped half-baked technologies of today.

There are all kinds of future energy storage solutions out there. But so far most of them hold little or no promise of even coming close to being economical. It’s going to take years or decades to develop them, and we have to be smart about how we do this. We cannot continue pouring money on something that will never work.

Yet, until bureaucrats wake up to this truth, expect many more Solyndras and Acquion Energy debacles in the years ahead.

  1. Hi,

    I started a PETITION “SA PREMIER JAY WEATHERILL : Demand the RESIGNATION of the Energy Minister for HIGH POWER PRICES CAUSING SA’s JOBS CRISIS and 15,000 household POWER DISCONNECTIONS, frequent POWER BLACKOUTS and the JULY 2016 POWER CRISIS” and wanted to see if you could help by adding your name.

    Our goal is to reach 200 signatures and we need more support.

    You can read more and sign the petition here:

    Please share this petition with anyone you think may be interested in signing it.

    Thankyou for your time.

  2. Just for fun I worked out how big a building would be needed to store these wonder batteries. When UK energy was supplied solely by the batteries, the building was the size of Somerset. Maybe let’s invest even more of our hard earned taxes with these greenies and see if we can get the size down so that it only takes up a few hundred football pitches

  3. For comparison “2,600MW Bayswater power station is valued at $780 million ”
    4000 MW costs $1.4 B, so the batteries alone cost 50 times as much as the equivalent coal power station.

  4. Michael Crawford says:

    On the $60-90B cost of necessary battery storage for SA, assuming a 10 year battery life, that works out to $3,500 – $5,300 p.a., per person in SA. Something like $10-15,000 per household p.a.

    This is just for storage, on top of the costs of generation and distribution, both of which have to rise with more wind turbines. So you take the already astronomical SA power prices, and whack on $10-15,000 per household.

    People will be going berserk to get into the aptly named Mr Weatherill’s comrade’s paradise.

  5. Peter Pronczak says:

    The girl who’s face was burnt when a small Lithium-Ion battery in her headphones caught fire, was obviously inside the pressurised aircraft from Beijing to Melbourne.
    They poured water over her; try doing that with solar panels or Mega Watts of batteries.

    The above makes an utter mockery of the following from Australia’s Civil Aviation Safety Authority (CASA)…https://www.casa.gov.au/standard-page/travelling-safely-batteries
    “Batteries under 100Wh rating
    The batteries that power your phone, laptop and camera are usually under the 100 watt-hour (Wh) rating.
    If you’re carrying a spare battery that’s not in one of these devices, it must be in your carry-on baggage only.
    Spare batteries, regardless of their size are not to be carried in checked luggage.”

    Above 100Wh batteries are declared ‘dangerous goods’ yet very few of the newer increasingly owned backup power batteries state what they are made of, mostly stating a recycle code of Li-Polymer which IS lithium-ion.

    Al Gore & David Blood aptly called Blood & Gore, are only interested in profit from the City of London Corporation’s casino economy usury system from the ETS, yes the ‘T’ stands for Trading, more correctly called gambling, but in this ‘house’ it never looses. From it’s small tax on the world’s biggest stock exchange the UK makes 17% of its income from the casino economy – it’s addicted.

    We can only guess at the damage that can be done from MW storage.
    As cold fronts come with low pressure atmospheric conditions…well who know what pressure blows them up.
