Vanadium ‘metal to watch’ in 2018, analyst says
Posted By: Trish Saywell January 3, 2018
Prices for vanadium — a minor metal traditionally used to strengthen steel and more recently a key component in a new generation of battery technology that could potentially store electricity from solar and wind generation — are expected to rise in coming years, Christopher Ecclestone of Hallgarten & Co. forecasts.Vanadium pentoxide (V2O5) prices moved from around US$5 per lb. at the end of December 2016 to US$12.50 per lb. at the end of July 2017, before closing the year at US$9.50 per lb., and the U.K.-based analyst predicts the price will reach US$13.20 per lb. by the end of 2018, US$15.00 per lb. by the end of 2019, and US$19 per lb. by the end of 2020.“Last decade vanadium surfaced as a subject of interest primarily tied to the fortunes of the then-booming steel industry,” he writes in a Jan. 3 research note. “Now vanadium is coming back with a vengeance for its potential in mass electricity storage devices, namely the vanadium redox battery, or VRB.”Vanadium pentoxide (98.5% pure) at the Rentian processing plant in China’s Jiangxi province.

The policy calls for the launch of pilot projects, including the deployment of multiple 100 megawatt-scale vanadium flow batteries by the end of 2020, with the aim of their large-scale deployment between 2020 and 2025.In November, Pu Neng, a privately held clean technology company that has developed a long-lasting vanadium redox battery, was awarded a contract for a 3-megawatt (MW) 12-megawatt-hour (MWh) VRB. The VRB is the first phase of a demonstration project in China’s Hubei province and, once completed, Pu Neng’s VRB will be the largest flow battery installed in China, the company says. As part of the initial agreement, Pu Neng and Hubei Vanadium will jointly develop a vanadium electrolyte supply from local vanadium sources to meet future demand.Friedland, Pu Neng’s chairman, commented in a press release on Nov. 1 that “China has the largest and highest-grade vanadium resources in the world and is poised to use this miracle metal to fundamentally transform its electricity grid.”A five ton-per-hour plant that processes uranium-vanadium ore using ablation technology.

When charging or discharging the battery, electrons are added into or drawn out of the electrolyte as it circulates across membranes inside the stacks. Unlike other types of batteries, the company outlines in the press release, vanadium flow batteries use the same electrolyte solution on both the positive and negative side of the battery, yielding a nearly infinitely repeatable electrochemical process. According to the company, its VRB “has more than 800,000 hours of demonstrated performance.”In his research note, Ecclestone says the surge in vanadium prices in the last six months has “sent investors (and promoters) scrambling to find primary vanadium mines or projects into which they could sink their teeth.”By some estimates, there are about sixteen listed vanadium companies worldwide, he says, which makes the metal “potentially a Vancouver promoters’ delight.”“However, as the promotorial class are sheep-like they won’t want to be interested (mind you, a good thing) until the price is significantly higher and the air is full of buzz,” he writes. “They are so high on lithium they need little else to stimulate their imaginations these days. At least so far, all the players we know of in the space are serious, which makes this metal a rarity in mining circles.”The most prominent producers that are accessible, he says, are Largo Resources (TSX: LGO; US-OTC: LGORF) and Bushveld Minerals (LON: BMN), while those with “serious short-term potential” include Western Uranium (TSXV: WUC).In December, Largo set a new production record at its Maracas Menchen vanadium mine in Brazil, producing 903 tonnes of vanadium pentoxide, 12.9% above the plant’s nameplate capacity.
