I'm no 'green cheerleader' but to claim that conventional plants last 80 years and don't use chrome, tungsten, vanadium nickel, vanadium etc. is definitely wrong. The typical coal or natural gas fueled power plant is designed with a useful life ranging from 20 to 40 years (usually about 35 years) There are a few out there in this world that are 80 years old, and they are invariably grossly inefficient highly polluting dinosaurs. Chrome, and nickel are critical elements in the high temperature high RPM turbine sections which are necessary for high efficiency plants. NIckel is critical for many green technologies but chromium is not. Tungsten isn't used to a significant degree in the electrical energy business directly, but all facets 'old and new' use a lot indirectly via machine tool eqiupment that manufactures parts. Vanadium is a preferential alloying element used in high temperature steel applications such as high pressure steam systems which are a critical part of fossil fuel electric plants. Vanadium is not currently a critical element in green technologies, although it could be in some future battery applications. Molybdenum isn't critical for any electric power generation systems - molybdenum is important where steels have to be lightweight, but electric power generation equipment is non-mobile, so saving weight is not a priority. 1 1 Quote Share this post Link to post Share on other sites

With the exception of copper, and of course iron the metal and mineral needs of the 'green energy' industry are mostly different from the needs of the 'fossil' fuel industry. Neodymium and Dysprosium WERE used in early machine with Permenant Magnet generators. That's OLD SCHOOL! Now it's just copper and silicon steel ELECTROMAGNETS! Along with power electronics, which uses silicon, which ain't exactly "rare. You do know what a Double Feed Induction Generator (DFIG) is, no? Using power electronics, it allows a variable speed input, with a synchronous power output, requiring NO rare earths at all. That's what on-shore machines now use. Offshore may still use permanent magnets, as they have may have a DC output (easier to transmit onto shore). On top of that, using a DFIG permits greater extraction of stored rotating inertia from a wind turbine. A conventional synchronous machine will trip once speed (RPM) drops about 2%, leaving the remaining stored rotating inertia unavailable to the grid. A DFIG can extract inertia down to MUCH lower speeds. Batteries, they require the same stuff (other than lithium, which ain't exactly rare either) fossil plants do. And I would not consider steel alloys that require 1% moly as low usage. You got 100 pounds of P22 low alloy pipe? You need 1 pound of moly. Steam plants use a LOT of high temp pipe. BIG, THICK stuff, too. Edited July 20, 2021 by turbguy 1 Quote Share this post Link to post Share on other sites
