South Korea issues tender for battery ESS in Jeju

Market: Battery materials, Electricity, Metals
17/08/23

South Korea plans to open the country's first central contract market for low-carbon power and has issued a tender for battery energy storage in Jeju province.

Power generators participating in this tender will build and operate long-cycle energy storage system (ESS) facilities that can operate for over four hours, the country's energy and industry ministry (Motie) said on 17 August. The winning bid will secure a long-term tender of 15-20 years, which will determine the price and volume through the ESS bidding market, and providers will be paid at the pre-contracted price when the facility is operating in the future. The tender will be awarded by the end of this year, with the successful bidder to be selected after a comprehensive evaluation of the bidding prices and non-price indicators such as technical capability.

The volume stated in the tender is 60MW/260MWh, with the capacity to charge and discharge 65MW for four hours. This is also the targeted volume of ESS that will be introduced next year, and corresponds to the volume required to stabilise the Jeju power grid in the short term.

The ministry expects the ESS to stabilise power supply in Jeju by storing surplus power and providing power during storage, alleviating the issue of the intermittency of renewable power generation. This is especially so since renewables make up a high proportion of Jeju's power mix.

Investment in industrial complexes

The Busan specialised complex has received 800bn won ($597mn) worth of corporate investments for the compound power semiconductor market, which is rapidly growing on the back of an electrification trend. Further investments of over W500bn in power semiconductor-related companies are being discussed, since Busan was designated as a specialised complex. Motie plans to launch a W138.5bn project to develop technology related to power semiconductors next year, and build a W26.5bn demonstration base.

The Ulsan secondary battery complex is home to 173 firms and Motie expects it to receive W8.1 trillion in private investment by 2030. The ministry also confirmed W700bn in new investments after Ulsan was designated as a specialised complex, with an additional W900bn under discussion. Ulsan city also plans to develop all-solid-state batteries and to build the country's first lithium-iron-phosphate battery production plant. It consequently plans to invest over W2 trillion to build facilities for mineral refining, smelting and precursor manufacturing.

Motie and Ulsan will invest W34bn by 2024 to establish a next-generation battery park.

Viewpoint: Trump, macro issues ahead for US renewables

Houston, 2 January (Argus) — A combination of substantial policy shifts under president-elect Donald Trump and macroeconomic issues puts the US renewable power sector on uncertain footing to begin 2025. Analysts expect the federal tax credits that have bolstered new renewable generation during its substantial growth over the past decade will survive in some fashion, although Trump campaigned on repealing the Inflation Reduction Act (IRA). He also has promised 60pc tariffs on goods imported from China, a major player in the solar and battery storage supply chains. The ultimate effects may vary by project type and what the new administration is able to accomplish. Chinese solar products already face 50pc tariffs , which could temper any effects on the industry from Trump's protectionist trade policies, said Tom Harper, a partner at consultant Baringa specializing in power and renewables. But the new administration could make it more difficult to claim IRA incentives and could roll back federal power plant emissions rules , creating an environment that could slow the adoption of renewables. Utilities may become more cautious in using renewables because of higher costs, while others, such as companies with sustainability goals, might be able to weather the change, according to Harper. "There might be some very price insensitive corporate [power purchase agreement] buyers out there who are looking at a $45/MWh solar [contract] and now it's going to be $50/MWh after the tariff, and they'll be fine," he said. In addition, the US renewables industry is still weathering headwinds from supply chain constraints, increased borrowing rates and inflation, which have hampered new projects. For example, the PJM Interconnection — which spans 13 mostly Mid-Atlantic states and the District of Columbia — had approved more than 37,000MW of generation at the end of third quarter 2024, with only 2,400MW of that partially in service. Developers have blamed the delays on financing challenges, long lead times for obtaining equipment and local opposition to projects. Global problems, local solutions Changes to state procurement strategies could help. Maryland state delegate Lorig Charkoudian (D) next year will propose new state-run solar, wind and hydropower solicitations that would first target projects that have already cleared PJM's reviews. Her approach would echo programs in New Jersey and Illinois, and ultimately reduce utilities' reliance on renewable energy certificates (REC) procured elsewhere. "The idea is to give a path for these projects, so presumably they can be built within a few years," Charkoudian said. Utilities would use the new procurements for the bulk of their RECs, covering remaining demand by buying legacy Maryland solar credits and other PJM RECs on the secondary market. But a quick fix for Maryland's broader renewable energy objectives is unlikely after utilities used the alternative compliance payment (ACP) for two-thirds of their 2023 REC requirements. The fee for each megawatt-hour by which utilities miss their compliance targets serves as a de facto ceiling on REC prices. Maryland's ACP is low compared to neighboring states, where the qualifying REC pool overlaps, meaning that credits eligible in the state can fetch a higher price elsewhere. While lawmakers could raise the ACP to mitigate those issues, those costs would ultimately fall on utility customers. "As best as I can tell, the options are raise the ACP or adjust how we do it," Charkoudian said. "We're really concerned about ratepayer impacts, and so I don't think there's a real appetite to raise the ACP." In other states, the policy landscape is less certain. Pennsylvania governor Josh Shapiro (D) has no clear path for his proposed hike to the state's alternative energy mandate, should he choose to revisit it, after Republicans retained their state Senate majority in November. New Jersey state senator Bob Smith (D) has been working for two years to enshrine in law governor Phil Murphy's (D) goal of 100pc clean electricity, but the proposal failed to escape committee in 2024 after dying in 2023 over opposition to its support for offshore wind . Is the answer blowing in the wind? Offshore wind is a slightly different matter. Trump has been critical of the industry and federal regulators control much of the project permitting in the US. Moreover, as a burgeoning sector with higher costs, it could be more sensitive to the loss of the investment tax credit (ITC). Based on current expenses, Baringa's analysis suggests that losing the ITC could increase project costs by "at least" $30/MWh and push offshore wind REC prices in some cases near $150/MWh. That would be a "difficult cost for states to swallow", according to Harper. "We've seen a few offshore wind developers already say, 'Hey, we're not going to spend a dime more until we know what's going on,'" Harper said. Despite the challenging landscape, Charkoudian expects Maryland will move forward in areas it can control, such as expanding the onshore transmission, that will make offshore wind viable, whether it's now or "eight years from now".

Pure green steel costs almost double NW EU HRC price

London, 2 January (Argus) — Zero emission hydrogen-fed electric arc furnace-produced crude steel would currently cost almost double the price of northwest EU hot-rolled coil (HRC), according to data launched by Argus today. The opex cost of green hydrogen-fed direct reduced iron/electric arc furnace (EAF) route steel was €1,074/t at the end of December, compared to a northwest EU HRC price of €558.25/t ex-works. That is also €544/t more than the cost of blast furnace/basic oxygen furnace (BOF)- produced crude steel, showing genuinely green steel would require a much higher finished product price than current blast furnace-based output, assuming a similar cost structure to today. Most current green offerings from EU mills are still produced via the blast furnace, with emissions reductions achieved through mass balancing, offsetting, or by reductions achieved elsewhere in the supply chain. Buy-side desire to pay premiums for this material has been limited, particularly given the downturn in the European market in the second half of 2024. This has contributed to the market for premiums remaining immature, illiquid and opaque, and complicated by the lack of a commonly agreed definition for green steel. Automakers have shown the most interest in greener steel, given their need to reduce emissions from the wider supply chain, as well as vehicle tailpipe emissions. Some automotive sub-suppliers suggest certain mills have been willing to reduce their green premiums to move tonnes — one reported paying a €70/t premium for EAF-based cold-rolled coil for a 2025 contract, but this was not confirmed. Europe's largest steelmaker, ArcelorMittal, said over the second half of last year it would pause its direct reduced iron (DRI) investment decisions ahead of the European Commission's Steel and Metals Action Plan, and as it called for an effective carbon border adjustment mechanism and more robust trade defence measures. Market participants largely agree that natural-gas fed EAF-based production is the greenest form of output currently available to EU mills, substituted with imports of greener metallics and semi-finished steels from regions with plentiful and competitively priced energy. Argus ' new costs show BOF steel is currently just over €31/t more expensive than scrap-based EAF production fed with renewable energy. Europe's comparatively high cost of energy is one key issue for transitioning to DRI/EAF fed production. Last month, consultancy Mckinsey said mills could rely on "green iron" hubs going forward, with iron-making decoupled from production of crude steel, enabling DRI production to be located in regions with low-cost gas and ore, and raw steel production in regions with access to renewable energy. The range of production costs, launched today, include five crude steel making pathways and are calculated using consumption and emissions data provided by Steelstat , in combination with Argus price data, including hydrogen costs.

Viewpoint: US utilities worry over railcar supply

Washington, 2 January (Argus) — US utilities are concerned that they may not have enough railcars to haul coal in the future as multiple power plants are seeking to remain in operation longer than expected. Power demand is forecast to rise in the coming years because of planned data centers in multiple parts of the country. Many data centers are expected to open before new generation, including natural gas, wind and solar-power units, go into service. A number of utilities want to avert the temporary power shortage by extending the life of coal-fired power plants beyond planned retirement dates. In response, demand is "poised to shift to a slight growth in the need for coal cars", according to railcar expert Richard Kloster, president of Integrity Rail Partners. Longer power plant lives as well as expectations of increased metallurgical coal exports are likely to provide demand for equipment. But the supply of railcars for coal has been slowly shrinking. No new railcars for the coal industry — primarily gondolas or open-top hoppers — have been built in nearly a decade. Utilities and leasing companies have had little interest in ordering new railcars for a shrinking sector. Many existing cars have also been scrapped, particularly during periods of low coal demand and high scrap prices during the last few years. There also are thousands of coal railcars in storage, but those do not really count towards demand, Kloster said. The cost of pulling those cars out of storage and making them service-ready is not necessarily cost effective, he said. About 21pc of North American coal cars were in storage at the beginning of August, up from 15pc in November 2022, according to Association of American Railroads data. In comparison, about 35pc of the coal car fleet was in storage at the start of July 2020, near the height of the Covid-19 pandemic. Possibilities of new construction There is a chance that "in the next 10 years, there will be coal cars built again", because many coal cars in the fleet are nearing 50 years of age, Kloster said. The retirement of many cars means that equipment must be pulled from storage or new units built, driving potential construction. Under Association of American Railroads (AAR) rules, railcars built after June 1974 can only be interchanged with other railroads for 50 years. After that, those cars are generally limited to operating on only one carrier. Some of those older cars may be retired early if they need repairs. Maintenance expenses could cause car owners to take units out of service. Utilities strategize Some utilities are already implementing plans to secure railcars, but others think taking additional steps will be unnecessary, according to railcar expert Darell Luther, chief executive of rail transportation firm Tealinc. The differing views are tied in part to whether utilities are regulated by states or merchant-owned, Luther said. Public utilities need to prove to regulators they can meet generating needs, including having enough coal and railcars. Privately owned operators have more flexibility in terms of contracting for coal and railcars. Several utility rail managers told Argus they do not see the need to take extra steps to secure railcars, confident that they already have plenty or can lease whatever they need in the future. But other utilities said they have taken steps to ensure they have coal cars in the future. Some utilities have purchased single or multiple cars as other generators sell them off. Others are increasingly leasing cars, with one utility saying that having more cars than needed is a cheap way of ensuring future supply.

Viewpoint: Gallium nitride to expand into auto industry

London, 2 January (Argus) — Gallium nitride (GaN) is already used in power devices for consumer electronics, but manufacturers are now developing the technology for use in the automotive sector, with the compound set to make its way into vehicles in the coming year. GaN semiconductors are currently used in consumer and industrial applications, including alternating current adapters and server power supply units. But use of GaN semiconductors in automotive applications is at an early stage — unlike silicon carbide (SiC) chips, which are increasingly being incorporated into electric vehicle (EV) power electronics. GaN has a similar crystalline structure to silicon but can deliver greater efficiency, faster switching speeds and higher thermal conductivity. Lower resistance, smaller form factors and the ability to operate at higher voltages mean GaN semiconductors consume less power than silicon semiconductors. Integrating GaN into silicon substrates rather than sapphire is opening up new uses for GaN in vehicle power devices and light detection and ranging (LiDAR). GaN is suitable for low and high-voltage applications for EVs, including on-board chargers (OBCs), power inverters and traction motors. US-based semiconductor firms Navitas Semiconductor and Texas Instruments (TI), and Chinese-owned Nexperia have been developing GaN chips for automotive for several years and are now moving quickly into higher voltages. Several manufacturers have now started producing devices and expect to gain traction over the next year. Navitas has been producing GaN devices since 2018 and expects to begin making the product for the automotive industry in 2025. Japan's ROHM Semiconductor in December partnered with the world's largest semiconductor company, Taiwan-based TSMC, to develop and produce GaN power devices for EVs. The companies will integrate ROHM's device development technology with TSMC's GaN-on-Si process technology and provide control integrated circuits to maximise performance. Israeli firm VisIC Technologies is developing GaN products for automotive and industrial uses. It announced plans in December to partner with Austrian automotive technology developer AVL to advance inverter technology for EVs. The firms aim to produce devices that offer higher performance and lower costs at both the device and system level, compared with SiC devices. VisIC's GaN-on-silicon power devices consume less energy during production and can be manufactured in 200mm and 300mm silicon foundries to scale up output. VisIC plans to work with AVL to expand the platform to include 800V power modules — the next generation of EV charging technology. China's Innoscience Technology is developing GaN-on-Si power products and recently launched two 100V automotive-grade devices optimised for LiDAR for advanced driver assistance and autonomous driving applications, as well as DC-DC converters and automotive audio applications. The company has started mass production and is fulfilling batch orders to meet demand. Several manufacturers and foundries are now building out capacity to accommodate commercial-scale output of GaN devices. US-based GlobalFoundries said in early December it has received $9.5mn in federal funding to continue adding new tools, equipment and prototyping capabilities at its Vermont facility, as it moves closer to full-scale manufacturing of its 200mm GaN-on-Si chips. And TI started producing GaN-based power semiconductors at its factory in Aizu, Japan, in October. As the site ramps up, TI's internal capacity will quadruple between its US and Japanese factories. The company has also piloted manufacturing 300mm wafers to increase volumes. Limitations in manufacturing have so far hampered the widespread adoption of GaN in EVs. Cost, supply-chain issues and concerns around thermal management and voltage spikes remain hurdles that manufacturers must overcome. The technology has yet to be proven for automotive applications, which have stringent standards for quality and safety. For this reason, manufacturers are starting with GaN in OBCs and converters to establish confidence. Companies such as Germany's Infineon and Swiss chipmaker STMicroelectronics anticipate there will be room for both SiC and GaN in the automotive sector, depending on the power, efficiency and cost requirements of the application. The availability of gallium compared with silicon may also become a factor as demand increases, given export restrictions out of primary supplier China.

Viewpoint: Strong fundamentals to support Nb columbite

London, 2 January (Argus) — Increased demand from the aerospace and defence industries, alongside reduced supply from Brazil, has underpinned a steady increase in niobium columbite prices over the past two years, although further rises could face resistance from smelters switching to ferro-niobium when columbite becomes too costly. Defence and aerospace demand supported prices across the niobium complex throughout last year and are set to continue driving demand this year, owing to continued geopolitical tensions across all regions. Total military spending globally rose to $2.4 trillion in 2023, up by about 6.8pc in real terms from 2022, data from the Stockholm International Peace Research Institute show. And figures for last year are expected to increase further as Russia's continued war in Ukraine spurred greater NATO spending, conflict escalated in the Middle East and the Red Sea, and China ramped up military drills around Taiwan. Niobium metal is used in a range of high-temperature alloys in aerospace and defence applications, thanks to its high strength at extreme temperatures. In September last year, the US Department of Defense awarded a $26.4mn grant to major tantalum and niobium producer Global Advanced Metals through the Defense Production Act programme to support the production of high-purity niobium oxides at the company's Pennsylvania plant. One key alloy to which niobium metal is crucial is C-103, used in hypersonic missiles, jet engine afterburners and satellite components. C-103 is made up of 89pc niobium, 10pc hafnium and 1pc titanium. Firm demand for niobium metal has been keenly felt by the columbite market — the raw material — in which prices averaged $18.20/lb cif main port from January-mid-December last year, compared with an overall average of $14.50/lb in the past five years. Columbite prices began to trend higher from late 2022 — before the sustained increase in defence and aerospace demand — bolstered instead by tightened supply. The election of Brazilian president Lula de Silva in October 2022 brought with it a government crackdown on artisanal mining on indigenous lands in the Amazon. While this crackdown has focused chiefly on illegal gold and zinc mining on indigenous lands, niobium columbite market participants have also noted tightened supply and higher prices from the region since the Lula government took office. Furthermore, conflict in the eastern part of the Democratic Republic of the Congo has decreased the supply of tantalite from key mining areas this year. Tantalite and columbite materially are similar, making tantalite a useful source of niobium concentrates to many Chinese smelters. But this lower supply has raised the prices of tantalite with higher niobium content, even while tantalum demand has been slow this year. Looking ahead, market participants expect columbite prices to remain firm throughout this year, supported by a continuation of the fundamentals of the past two years. But further price increases could face resistance from consumers, as smelters could switch to ferro-niobium to avoid higher columbite costs. In the past, smelters in China have made the switch to ferro-niobium when columbite prices climb above $18/lb, often causing increases beyond this level to be short-lived.
