Claim: Expensive Vanadium Flow Batteries will Make Renewable Energy Viable
By Eric Worral | Watts Up With That? | December 21, 2020
Vanadium is expensive, though the price fluctuates wildly – currently $11K to $15K / tonne of Vanadium Pentoxide. But advocates claim Vanadium flow batteries have the potential to solve the intermittency of renewable energy.
StorEn Tech Provides First Of Its Kind Vanadium Flow Battery To Australia
December 19th, 2020
Australia has taken another step toward greater use of battery energy storage thanks to a new 30 kWh StorEn vanadium flow battery that was installed for use in a renewable hydrogen plant at Queensland University of Technology (QUT).
The battery, which was provided through a partnership between StorEn Technologies Inc.* and Multicom Resources Limited, will allow researchers in Australia to develop safety standards for the future use of vanadium flow batteries as well as helping to bring the technology to Australia.
The many features of vanadium flow batteries could make them ideal for grid-scale energy storage, which is something that Australia is looking to expand in the coming years. […]
Peter Talbot, a professor at QUT, said about the new battery — “vanadium flow battery technology promises safe, affordable and long-lasting energy storage for both households and industry.” […]
Vanadium has an energy density of 15-25Wh / L, so to provide backup for a 1GW renewable plant for a day, you would need:
24 x 1GW = 24GWh of storage, or 24,000,000,000 Wh / 25 Wh / L = 960 million litres of Vanadium electrolyte – say a couple of billion dollars worth.
An expensive battery, but not an unimaginable expense.
Of course a single day of backup capacity is not nearly enough. Wind droughts can last weeks or even months. So if your goal is to match the reliability of fossil fuel generators, you are going to need a lot more than a couple of billion dollars worth of electrolyte.
You might find that the electrolyte gets a lot more expensive over the course of negotiating your battery purchase agreement. The global Vanadium market is small, around 80,000 tons per year. So an attempt to purchase several hundred thousand tons of Vanadium to build a 1GW battery would have a substantial impact on global prices.
Assuming you somehow obtain enough Vanadium for your battery, your Vanadium Flow battery electrolyte cannot be allowed to overheat or freeze. So your new battery complex will need substantial air-conditioning, which will eat into its storage efficiency.
Vanadium has other important industrial uses. Vanadium is used as a steel additive to produce high strength structural steel, and is also an important component of military grade steel alloys, and critical steel components subject to high stress, such as automobile crank shafts. China is a substantial buyer in the global Vanadium market.

American Pravda: How the CIA Invented “Conspiracy Theories”
BY RON UNZ • UNZ REVIEW • SEPTEMBER 5, 2016
A year or two ago, I saw the much-touted science fiction film Interstellar, and although the plot wasn’t any good, one early scene was quite amusing. For various reasons, the American government of the future claimed that our Moon Landings of the late 1960s had been faked, a trick aimed at winning the Cold War by bankrupting Russia into fruitless space efforts of its own. This inversion of historical reality was accepted as true by nearly everyone, and those few people who claimed that Neil Armstrong had indeed set foot on the Moon were universally ridiculed as “crazy conspiracy theorists.” This seems a realistic portrayal of human nature to me.
Obviously, a large fraction of everything described by our government leaders or presented in the pages of our most respectable newspapers—from the 9/11 attacks to the most insignificant local case of petty urban corruption—could objectively be categorized as a “conspiracy theory” but such words are never applied. Instead, use of that highly loaded phrase is reserved for those theories, whether plausible or fanciful, that do not possess the endorsement stamp of establishmentarian approval.
Put another way, there are good “conspiracy theories” and bad “conspiracy theories,” with the former being the ones promoted by pundits on mainstream television shows and hence never described as such. I’ve sometimes joked with people that if ownership and control of our television stations and other major media outlets suddenly changed, the new information regime would require only a few weeks of concerted effort to totally invert all of our most famous “conspiracy theories” in the minds of the gullible American public. The notion that nineteen Arabs armed with box-cutters hijacked several jetliners, easily evaded our NORAD air defenses, and reduced several landmark buildings to rubble would soon be universally ridiculed as the most preposterous “conspiracy theory” ever to have gone straight from the comic books into the minds of the mentally ill, easily surpassing the absurd “lone gunman” theory of the JFK assassination.
Even without such changes in media control, huge shifts in American public beliefs have frequently occurred in the recent past, merely on the basis of implied association. In the initial weeks and months following the 2001 attacks, every American media organ was enlisted to denounce and vilify Osama Bin Laden, the purported Islamicist master-mind, as our greatest national enemy, with his bearded visage endlessly appearing on television and in print, soon becoming one of the most recognizable faces in the world. But as the Bush Administration and its key media allies prepared a war against Iraq, the images of the Burning Towers were instead regularly juxtaposed with mustachioed photos of dictator Saddam Hussein, Bin Laden’s arch-enemy. As a consequence, by the time we attacked Iraq in 2003, polls revealed that some 70% of the American public believed that Saddam was personally involved in the destruction of our World Trade Center. By that date I don’t doubt that many millions of patriotic but low-information Americans would have angrily denounced and vilified as a “crazy conspiracy theorist” anyone with the temerity to suggest that Saddam had not been behind 9/11, despite almost no one in authority having ever explicitly made such a fallacious claim.
These factors of media manipulation were very much in my mind a couple of years ago when I stumbled across a short but fascinating book published by the University of Texas academic press. The author of Conspiracy Theory in America was Prof. Lance deHaven-Smith, a former president of the Florida Political Science Association.
Based on an important FOIA disclosure, the book’s headline revelation was that the CIA was very likely responsible for the widespread introduction of “conspiracy theory” as a term of political abuse, having orchestrated that development as a deliberate means of influencing public opinion. … continue

Three Mile Island, Global Warming and the CIA
By Aletho News | January 9, 2012
There appears to be something about launching bombs or missiles from afar onto cities and people that appeals to American military and political leaders. In part it has to do with a conscious desire to not risk American lives in ground combat. And in part, perhaps not entirely conscious, it has to do with not wishing to look upon the gory remains of the victims, allowing American GIs and TV viewers at home to cling to their warm fuzzy feelings about themselves, their government, and their marvelous “family values”. Washington officials are careful to distinguish between the explosives the US drops from the sky and “weapons of mass destruction” (WMD), which only the officially-designated enemies (ODE) are depraved enough to use. The US government speaks sternly of WMD, defining them as nuclear, chemical and biological in nature, and “indiscriminate” (meaning their use can’t be limited to military objectives), as opposed to the likes of American “precision” cruise missiles. This is indeed a shaky semantic leg to stand on, given the well-known extremely extensive damage to non-military targets, including numerous residences, schools and hospitals, even from American “smart” bombs, in almost all of the bombings listed below.
Moreover, Washington does not apply the term “weapons of mass destruction” to other weapons the US has regularly used, such as depleted uranium and cluster bombs, which can be, and often are, highly indiscriminate. … continue
