Titanium Metals Company, higher referred to as Timet, is developing a brand new manufacturing facility on the location of a former aluminum smelter in West Virginia. Ordinarily, a brand new enterprise like that might notify the native utility firm that its wants a considerable amount of electrical energy to energy its furnaces, and the utility firm would take it from there. However Timet is doing issues in a different way. It’s working with BHE Renewables to put in a photo voltaic and battery storage system subsequent door. Each Trimet and BHE Renewables are Berkshire Hathaway firms. Because the Trimet operation expands, the photo voltaic and battery set up will develop proper together with it to produce its electrical wants within the years forward.

There are a number of issues occurring right here. One, this association is among the many first within the US to straight energy a big industrial facility utilizing photo voltaic plus storage know-how. Builders say they hope the setup can function a mannequin for future manufacturing vegetation as the US ramps up home manufacturing of electrical vehicles, photo voltaic panels, batteries, and the metal, aluminum, and different important supplies used to make them. Two, it’s a shot throughout the bow of the utility business, a warning that their enterprise mannequin is weak to new concepts.

Native Versus Distant Energy

Firstly of the so-called Industrial Revolution, water wheels have been the supply of energy for mills. Later, steam took over. Each have been strictly native energy sources. However electrical energy is completely different. It may be transmitted by wires over lengthy distances, which provides some individuals the concept we may energy New York Metropolis with solar energy from California. Whereas that’s technically attainable, it means constructing 1000’s of miles of new transmission strains. Not solely is doing so frightfully costly, it raises the hackles of individuals close to these transmission strains who don’t a lot look after the concept of seeing towers and wires out their home windows. Getting renewable power tasks to {the electrical} grid can be a torturous course of that may take years.

Creating electrical energy proper subsequent to the place it’s wanted solves lots of these points. It additionally provides giant customers of electrical energy the satisfaction of figuring out the value they pay for it will likely be steady for 20 years or extra. Dan Winters, vp of communications and public relations for BHE Renewables, advised Canary Media the Timet undertaking in West Virginia ​“demonstrates the flexibility of a microgrid to fulfill industrial prospects’ calls for, together with … delivering renewables the place and when they’re wanted, and driving financial revitalization via manufacturing backed by clear power. He added that constructing an on-site microgrid improves ​“time to energy,” which means the period of time it takes to construct and join power assets. At the moment, connecting photo voltaic, wind, and storage tasks on to {the electrical} grid sometimes takes greater than three years, owing to the rising backlog of latest power tasks in search of transmission connections.

Native photo voltaic for native prospects. What an idea! In fact, it helps that the Timet manufacturing facility is situated on 2000 acres of a former industrial website. Not each producer could have that luxurious. Timet stated its new plant will embrace two sorts of electricity-driven furnaces to generate intense warmth for melting titanium sponge and scrap. Initially, the melting plant is predicted to want round 18 megawatts of energy to function, earlier than ramping as much as its full capability of 106 MW by the top of 2027. The photo voltaic microgrid will scale up in lockstep with Timet’s operations.

When absolutely constructed, the BHE Renewables undertaking will embrace a 106 MW photo voltaic array and a battery power storage system with the capability of to ship 50 MW of electrical energy for 5 hours. The batteries are anticipated to make use of lithium iron phosphate know-how. The provider of the batteries has not be introduced. The photo voltaic plus battery system will present the ​“constant, dependable energy provide” that melting furnaces require at a value that’s similar to conventional energy sources,” stated David Dugan, director of company communications for Timet’s mother or father firm, Precision Castparts Corp.

The Titanium Conundrum

As a steel, titanium is twice as robust as aluminum. It’s almost as robust as metal however weights solely half as a lot. So why isn’t it used extra? Primarily as a result of making titanium requires monumental quantities of electrical energy, which makes it too costly for many potential purposes.  “Titanium must be used much more in our each day lives and within the business,” given its optimistic qualities, in response to Zhigang Fang, an professional in titanium metallurgy and a professor on the College of Utah in Salt Lake Metropolis. ​“However it’s solely a tiny fraction in comparison with metal, and that’s as a result of it is extremely costly.” He estimated {that a} kilogram of major titanium steel prices about 20 occasions greater than a kilogram of metal.

Titanium happens within the earth’s crust primarily within the type of ilmenite, a heavy, opaque mineral that’s primarily mined in China, Mozambique, South Africa, and Canada. As a chemical aspect, titanium quickly reacts with oxygen within the air, which creates the compound titanium dioxide. To take away the oxygen, firms use what’s referred to as the Kroll course of. To start out, titanium ore is heated to 1,800 levels Fahrenheit and reacted with chlorine fuel and carbon-rich petroleum ​“coke.” This step yields a liquid chemical, titanium tetrachloride, and in addition produces carbon dioxide as a byproduct in a lot the identical means as blast furnaces used for making iron do. The liquid chemical then undergoes one other therapy utilizing molten magnesium, which ends up in porous, sponge-like pure titanium steel.

The US has not produced its personal titanium sponge since 2020, when Timet closed the nation’s final remaining manufacturing line in Henderson, Nevada, although the corporate nonetheless melts titanium there. At the moment, the U.S. imports most of its titanium sponge provide from Japan and, to a lesser extent, from Kazakhstan.

Competitors from lower-cost imports and slumping steel costs globally made it tough for US producers to maintain making sponge domestically. Rising power prices additionally strained operations, as they’ve for different energy-intensive industries, together with home aluminum manufacturing. When Century Aluminum lastly shuttered its smelter in West Virginia in 2015, the corporate cited excessive electrical energy costs as one of many primary causes. Timet is constructing its titanium facility on the previous Century Aluminum website.

Discovering cleaner sources of electrical energy to energy titanium amenities may assist to regulate and probably cut back prices related to producing titanium merchandise. However firms and researchers are additionally creating various strategies for making titanium that purpose to dramatically cut back power use and curb carbon dioxide emissions throughout the provision chain. On the College of Utah, Fang developed a novel thermo-chemical course of that makes use of hydrogen to separate titanium from oxygen at comparatively low temperatures and in a fraction of the time that typical strategies require. That course of can use scrap steel to provide excessive purity titanium, which eliminates a number of different power intensive steps.

On a life cycle foundation, the hydrogen-assisted metallothermic discount (HAMR) course of can cut back CO2 emissions from titanium manufacturing by 50 to 95%. Fang’s analysis crew obtained round $7 million in complete federal funding to develop the HAMR course of, together with from the Division of Vitality’s Superior Analysis Initiatives Company –Vitality. The North Carolina–primarily based firm IperionX later acquired each the know-how and a pilot plant in Utah, which might produce about 2 metric tons of titanium per 12 months, primarily for prototypes.

Dominic Allen, chief business officer for IperionX, stated the corporate is working to ​“reshore” U.S. titanium manufacturing partly for nationwide safety causes. At the moment, China and Russia management about 70% of the world’s marketplace for major titanium. IperionX additionally hopes that by making much less power intensive and cheaper titanium domestically, the steel can increase into new markets, probably changing aluminum and chrome steel in automobiles and constructing supplies.

“The titanium market is round $4 billion globally,” Allen stated, including that the worldwide markets for aluminum and chrome steel are round $170 billion and $200 billion, respectively. ​“So when you can simply take a fraction of these markets simply on worth alone, it’s going to be monumental progress within the titanium market from the place it’s in the present day.”

The Takeaway

Digging into the main points of how titanium is made illustrates simply how energy-intensive the method is and the way it includes important carbon emissions. Producing the electrical energy for making titanium on-site will assist tame a few of these emissions. New applied sciences such because the HAMR course of could eradicate extra of these emissions. For many years we ignored emissions from business — they have been simply one thing we needed to put up with if we wished cement, metal, or titanium. The truth that some individuals in the present day are considering of how to curb these emissions is welcome information.
