As part of ensuring a resilient renewable energy grid, governments should work together to encourage the free trade of renewable power across borders. While President Biden has not directly mentioned importing renewable power, he stated in a direct reference to Canada that no source of clean power is off the table. That said, the most recent text of the U.S. House of Representatives budget reconciliation bill would give a 10 percent credit under the Section 136101 Credit for Electricity Produced from Certain Renewable Resources for renewable energy products domestically produced in the United States. Another step in encouraging greater sustainability in the aluminum industry is to deploy better recycling technology. Heat for the dissolution process is typically provided by steam generated by on site coal or natural gas boilers while the high temperatures required for calcination invariably mean direct fossil fuel combustion (i.e. Steel accounts for 15 percent of Chinas carbon emissions, the most of any manufacturing sector in China, while aluminum accounts for nearly 4 percent. It is also relevant from an Australian perspective because not only do we have a large domestic aluminium industry that employs lots of Australians and contributes meaningfully to export earnings but also because it is an industry that, according to many, often conservative, commentators, is at risk from net zero carbon policies . Will China (or perhaps middle eastern nations) take the lead in trialing carbon capture and storage for aluminium smelting? Technical Decarbonising the aluminium industry will be an interesting mix of the evolution of a zero carbon electricity, the development of low carbon technologies for generic processes such as industrial steam and high temperature calcination and potentially the roll out of some transformative smelting changes that will be unique to the industry. Both examples highlight the difficulties in decarbonizing entire industries in the face of persistent fluctuations of supply and demand regarding goods and energy alike. Several aluminum firms have also signed billion-dollar long-term Al-Li supply contracts with Boeing, Airbus, and other major aircraft manufacturers. By mid-century, in an IAE Beyond 2 Degree (B2DS) scenario, these emissions would be reduced to near zero, as fossil fuels would be phased out or replaced with carbon capture, use and storage (CCUS - Carbon dioxide Capture & Utilization or Storage). Europe and China serve as cautionary examples for how to avoid some of the pitfalls of the volatility of energy markets. Decarbonising our Iron Ore business. Chinas 14th Five-Year Plan for 20212025 charts targets for steel and aluminum carbon optimization that ministries, provinces, and firms have begun to enact. This plurilateral could serve as a distinct, standalone plurilateral, similar to the Agreement on Climate Change, Trade, and Sustainability (ACCTS). Though still in R&D, the technologywhen coupled with hydropower energy sourcingaims to become commercially viable by 2024. Despite a 1989 law aimed at reducing landfill waste by 50 percent by 2010, West Virginia has not made any progress toward that goal. The downstream segment refers to the production of semi-fabricated aluminum products and their use in a wide range of sectors, from manufacturing and automobiles to construction and consumer products. Aluminium smelting is extremely intolerant to even short interruptions to the supply of electricity. In the cases of both steel and aluminum decarbonization in China, high ambitions have yet to translate to tangible results. In most cases, these result in regional groupings. Note that the low-carbon French electricity mix is an asset for the sector and that primary aluminum imports are generally more carbon-intensive than national production. In 2020, 67 percent of Canadian electricity came from hydropower, while 60 percent of U.S. power came from fossil fuels, largely natural gas. Production of these carbon based gases will obviously be eliminated if inert anode technology can be commercialised but even without this innovation the volumes of these gases emitted due to poor cell operation has decreased dramatically over the past few decades with the advent of advanced computer controls and the replacements of aging smelters with newer facilities. Through combined actionboth at the domestic and international levels and through private and public sector engagementthe world can make meaningful progress on reducing global emissions by accelerating the decarbonization of aluminum. However, absent China, the deal represents relatively limited progress in the immediate term. Every minute in the United States, 105,784 aluminum cans are recycled, contributing to an industry average of 73 percent recycled content in a given aluminum beverage can. As a result, steel and aluminum decarbonization have been made key government priorities. With some of the worlds least carbon-intensive aluminum sectors, the European Union and United States should work to ensure other countries join them in helping build a virtuous circle of trade and climate policy. The European Unions decarbonization efforts present an opportunity for closer climate collaboration with both the United States and China, although closer collaboration would likely be contingent upon the creation of a U.S. emissions trading scheme and a higher domestic price of carbon in China. Aluminum is one of the world's most widely used metals. The plan aims to invest $8 billion in green hydrogen, establish a Buy Clean task force, and leverage carbon-based trade, such as the Global Arrangement on Sustainable Steel and Aluminum, to decarbonize heavy industry. In the United States, the recycling rate for aluminum is 49.8 percent, versus 76.3 percent in Europe, meaning that additional incentives to recycle could help fill an important gap that would encourage reuse while reducing pressure to produce virgin aluminum. While steel output declined in the historic production hubs of Hebei and Tianjin in the north, these reductions were offset by production increases in all other provinces. Where electrification is not feasible, green hydrogen, concentrated solar thermal energy and the use and storage of carbon dioxide (CCUS) are the best options. With that funding, Alcoa is exploring using mechanical vapor recompression that could help convert waste vapor into steam, ultimately reducing one refinerys carbon footprint by 70 percent. CBAM certificate prices will be calculated as the average weekly auction price of the EU Emissions Trading System (ETS) allowances, and credit will be given to non-EU producers for any carbon price paid in their country of domestic production. Coal supply shortages have been exacerbated by an unofficial import ban on Australian coal shipments due to tense political relations between the two countries. The carbon specifics of the agreement remain murky, and the United States and European Union have agreed only to negotiate plans that consider the carbon intensity and global overcapacity of steel and aluminum. Nevertheless, decarbonizing upstream aluminum offers the most immediate and efficient way of achieving deep decarbonization. If encouraging firms to reshore is a government goal, one way to do that without penalizing firms is for the U.S. government to invest in renewable energy that allows companies to take advantage of cheap, renewable electricity. Rapid demographic and economic growth over the next few decades means that global demand for aluminum will increase by up to 80% by 2050. 2022 by the Center for Strategic and International Studies. The estimated cost of decarbonizing the aluminum sector ranges from $500 billion to $1.5 trillion. Whether this gets the industry to net zero by 2050 or not remains to be seen and progress will depend on both regulatory changes and successful technical innovation and implementation. The prevalence of aluminum-lithium (Al-Li) composites is growing, with Alcoa investing $90 million in the worlds largest Al-Li production facility in Indiana. The United States and Canada have similar carbon neutrality goals for their electricity sectors. In a scenario beyond 2 degrees (Beyond 2 Degree - B2DS), the industry is expected to reduce its total emissions to 250 million C02e emissions, from a baseline of 1.1 billion CO2 emissions in 2018 and a Business asUsual scenario. Also in November, the House of Representatives passed the BBBA, which allocates $555 billion to fight climate change. Yet producing aluminium generates up to six times more carbon emissions than steel and requires huge amounts of electricity. China is the largest producer with close to 60% of total world output. Required fields are marked *. Removing emissions from the smelting process is a common challenge for all manufacturers and will require profound technological change. Determining a common threshold at which countries can designate aluminum as decarbonized is a necessary step and one that should accompany a more detailed effort to reach a global agreement on methodologies for carbon content of goods. Above all, the different experiences of aluminum firms around the world, from China to Iceland, underscore the importance of a diversified and reliant renewable energy supply. A common methodology would also serve as a guardrail for trade policy that encourages countries to use trade to adopt a virtuous circle rather than a race to the bottom in which an increasing number of trade barriers are adopted. The European Unions recently proposed Carbon Border Adjustment Mechanism (CBAM) seeks to limit carbon leakage and encourage a race to the top when it comes to environmental standards and emissions reductions. (3) there are real technical challenges that need to be overcome to make the aluminium zero carbon. 1512), would help expand on subnational success. The most cost-effective way to produce sustainable aluminum, which is now price competitive with traditional, fossil-fuel-based aluminum, is by sourcing electricity from renewable energy sources, such as hydro, solar, and wind power. Maines success can be attributed to their strong container deposit laws, or bottle bills, which have the highest deposit rates among the 10 states and Guam that provide refunds for aluminum can recycling. However, of the 3,890,000 tons of aluminum produced in 2018 in the United States, only 670,000 tons of it were recycled, meaning the vast majority of aluminum produced ended up in landfills. That is probably correct but it will be interesting to see if there is condemnation of government assistance to big polluters who, in many cases, will need both carrot and stick regulations if they are to make massive investments in new, potentially untried equipment. Technically almost anything is possible with enough time and money but for some refineries and smelters the journey to zero carbon means they will need to close causing collateral damage (and some celebration) in local communities. The entire aluminium industry needs a decarbonisation strategy that is both broad and deep. Given the considerable amount of electricity consumed in the aluminium subsector, decarbonising its power sources would help reduce indirect emissions and is thus a key complement to reducing direct aluminium emissions. The owners will also be aware that alumina refineries are not pretty places with waste streams that create genuine, localised environmental challenges. Another way that governments can facilitate decarbonization of heavy industry is to ensure that renewable energy can be traded freely across borders. This instinct would be broadly correct but there is plenty of nuance in navigating this shift. The IAI position paper, Aluminum Sector Greenhouse Gas Pathways to 2050, presents a complete map of the path to reduce greenhouse gas emissions for the decarbonisation of the aluminum industry over the next three decades. This process relies on the fact that aluminium oxide dissolves in Sodium Hydroxide (NaOH) at temperatures of around 150 250C allowing it to be separated from undesirable components of the ore which do not dissolve. Abdulnasser bin Kalban, the CEO of EGA, said, "Aluminium's use plays a key role in decarbonising other industries economy-wide, which makes decarbonising aluminium production even more of an. More optimistically, refineries could become customers for a local green hydrogen industry or even advanced solar technology, a scenario that governments may be keen to encourage. The European Union and United States have long contended with two interrelated problems: Chinese dumping of steel and aluminum, and Chinese carbon emissions that have continued to grow despite the urgent need to decarbonize. The bad news is that even with these conceptual pathways, decarbonisation remains a complex and challenging task for large scale, energy intensive industrial installations like alumina refineries. Ultimately the aim is for financial institutions to adopt the framework in early 2023 and set global practices on climate for aluminium finance. In addition to adjusting pricing schemes, China has ordered more coal to be mined and has increased imports of coal, primarily from Russia and Indonesia. However, the upper limit for aluminum companies to transition to renewable power is roughly $40 per megawatt hour of power. In their recent joint statement regarding steel and aluminum, the European Union and United States jointly attempt to reconcile both these problems in a way that would decrease market access for more carbon-intensive products, while increasing protections for domestic EU and U.S. producers whose aluminum is far more climate competitive than Chinese products. For example, a project at the University of Michigan aims to provide insights on how to better design automobiles so that the ease of scrapping and recycling is taken into account during the initial design phase. Aluminium is an interesting decarbonisation case study from a global perspective for a number of reasons: (1) it is an important material that plays a key role for all advanced economies (ie aluminium will continue to be needed in a post carbon world), (2) like many major industrial products, its contribution to global CO2 emissions in not insignificant according to the World Aluminium Association about 2% of global GHG emissions result from aluminium production processes (3). To enhance recycling efficiency, facilitiesmust haveaccesstosorting technology such asmanualeddy current separators, which sort recycling inputs by material type,as well as the moreadvancedX-ray transmission technologyfor metals. Concerns of steel supply shortages from closing energy-intensive plants have led Chinas Customs Tariff Commission of the State Council to shift its trade policy, raising export tariffs and lowering import tariffs on steel. Broadly, sustainable aluminum is aluminum that (1) is produced with a high percentage of renewable power, (2) leverages new technologies to streamline processing, (3) minimizes and eliminates waste and, (4) maximizes product end-of-life cycles through recycling. Alumina Refineries the refining of bauxite into alumina uses a preferential dissolution process that is more or less unique to the aluminium industry. Emissions from aluminium production can range from around 3 tons of CO 2 per ton of aluminium up to around 19 tons. This highlights the difficulty of decarbonizing a major Chinese growth industry in the face of sustained global demand for steel. The split between processing steps was estimated to be, Smelting (including anode production and casting) 862 billion tonnes (81.3%). As currently proposed, the EU CBAM appears to comply with both criteria, particularly since varying carbon content of goods affects the likeness of products traded. To incentivize firms to decarbonize aluminum, renewable energy must be both affordable and reliable. The EU-U.S. Joint Statement on steel and aluminum provides a roadmap on the rules that may be jointly developed to address non-market excess capacity and carbon intensity. While government intervention has primarily focused on trade remedies and environmental standards, the aluminum sector itself has led efforts to decarbonize, particularly via new technology in upstream and downstream production to create sustainable aluminum. However,the location of renewable energy production, such asoffshorewind farms or major solar fields, is oftendistant fromproduction facilities, meaning that electricity must travel far to reach the end user. Another way that governments can facilitate decarbonization of heavy industry is to ensure that renewable energy can be traded freely across borders. The Environmental Protection Agency (EPA) and aluminum industry have worked in concert to improve efficiency of aluminum production and reduce sectoral emissions of perfluorocarbons (PFCs or PFAS), which are potent GHGs released during primary aluminum production that trap heat in the atmosphere.
