Rio Tinto considers hydrogen to cut alumina emissions
UK-Australian resources firm Rio Tinto is partnering with the Australian Renewable Energy Agency (Arena) to study whether hydrogen can replace natural gas in alumina refineries to reduce emissions.
Rio Tinto will carry out a feasibility study, equally funded with Arena, into using hydrogen produced from renewable energy to replace natural gas in the calcination process of refining at the firm's Yarwun alumina refinery at Gladstone in Queensland.
The study includes work at Rio Tinto's Bundoora technical development centre in Melbourne, where in-house development has been extended to hydrogen. It will investigate potential technology that can contribute to the decarbonisation of the Australian alumina industry.
Rio Tinto, which has bauxite, alumina and aluminium operations, is aiming to reach net-zero emissions across its operations by 2050. It is targeting a 15pc cut in absolute emissions and a 30pc reduction in emissions intensity by 2030 from a 2018 baseline.

EU adopts Net-Zero Industry Act
EU adopts Net-Zero Industry Act
London, 26 April (Argus) — Members of the European Parliament (MEPs) have adopted Net-Zero Industry Act, which plans to allocate funds towards the production of net-zero technologies. The act provides a pathway to scale up development and production of technologies that are critical towards meeting the EU's recommendation of net-zero greenhouse gas (GHG) emissions by 2050. This would include solar panels, electrolysers and fuel cells, batteries, heat pumps, onshore and offshore wind turbines, grid technologies, sustainable biomethane, as well as carbon capture and storage (CCS). The act is designed to help simplify the regulatory framework for the manufacture of these technologies in order to incentivise European production and supply. It also sets a target of 40pc production within the EU for its annual "deployment needs" of these technologies by 2030. Time limits will be instated on permit grants for manufacturing projects, at 12 months if the manufacturing capacity is under 1 GW/yr and 18 months for those above that. It will introduce time limits of nine months for "net-zero strategic projects" of less than 1 GW/yr and 12 months for those above. This is further complemented by the introduction of net-zero strategic projects for CO2 storage, to help support the development of CCS technology. The act was met with positive reactions from the European Community Shipowners' Association (ECSA), which said the bill will set the benchmark for member states to match 40pc of the deployment needs for clean fuels for shipping with production capacity. ECSA said the Net-Zero Industry Act will be instrumental in supporting the shipping industry to meet targets set under FuelEU Maritime regulations , which are set to come into effect next year.

New technologies aim to boost SAF production
New technologies aim to boost SAF production
London, 26 April (Argus) — A likely rise in global demand for sustainable aviation fuel (SAF), underpinned by mandates for its use, is encouraging development of new production pathways. While hydrotreated esters and fatty acids synthesised paraffinic kerosine (HEFA-SPK) remains the most common type of SAF available today, much more production will be needed. The International Air Transport Association (Iata) estimated SAF output at around 500,000t in 2023, and expects this to rise to 1.5mn t this year, but that only meets around 0.5pc of global jet fuel demand. An EU-wide SAF mandate will come into effect in 2025 that will set a minimum target of 2pc, with a sub-target for synthetic SAF starting from 2030. This week the UK published its domestic SAF mandate , also targeting a 2pc SAF share in 2025 and introducing a power-to-liquid (PtL) obligation from 2028. New pathways involve different technology to unlock use of a wider feedstock base. US engineering company Honeywell said this week its hydrocracking technology, Fischer-Tropsch (FT) Unicracking, can be used to produce SAF from biomass such as crop residue or wood and food waste. Renewable fuels producer DG Fuels will use the technology for its SAF facility in Louisiana, US. The plant will be able to produce 13,000 b/d of SAF starting from 2028, Honeywell said. The company said its SAF technologies — which include ethanol-to-jet , which converts cellulosic ethanol into SAF — have been adopted at more than 50 sites worldwide including Brazil and China. Honeywell is part of the Google and Boeing-backed United Airlines Ventures Sustainable Flight Fund , which is aimed at scaling up SAF production. German alternative fuels company Ineratec said this week it will use South African integrated energy firm Sasol's FT catalysts for SAF production. The catalysts will be used in Ineratec's plants, including a PtL facility it is building in Frankfurt, Germany. The plant will be able to produce e-fuels from green hydrogen and CO2, with a capacity of 2,500 t/yr of e-fuels beginning in 2024. The e-fuels will then be processed into synthetic SAF. Earlier this month , ethanol-to-jet producer LanzaJet said it has received funding from technology giant Microsoft's Climate Innovation Fund, "to continue building its capability and capacity to deploy its sustainable fuels process technology globally". The producer recently signed a licence and engineering agreement with sustainable fuels company Jet Zero Australia to progress development of an SAF plant in north Queensland, Australia. The plant will have capacity of 102mn l/yr of SAF. Polish oil firm Orlen formed a partnership with Japanese electrical engineering company Yakogawa to develop SAF technology . They aim to develop a technological process to synthesise CO2 and hydrogen to form PtL SAF. The SAF will be produced from renewable hydrogen as defined by the recast EU Renewable Energy Directive (RED II) and bio-CO2 from biomass boilers, Orlen told Argus .

Japan’s JBIC to finance Chilean copper mine development
Japan’s JBIC to finance Chilean copper mine development
Osaka, 26 April (Argus) — Japan is enhancing its financial support for the development of copper mines in Chile, as part of efforts to increase its self-efficiency of base metals. State-owned Japan Bank for International Co-operation (JBIC) on 25 April signed a $248mn loan agreement with Chile-based joint-venture Compania Minera Arqueros (CMAQ) to finance development of its Arqueros copper project in Chile. CMAQ is 80pc owned by Japanese copper producer Nittetsu Mining and 20pc by Chilean firm Fondo de Inversion Privado Talcuna. The load will be co-financed by other Japanese private-sector financial firms, including Sumitomo Mitsui Banking, Mizuho Bank and MUFG Bank. The total co-funding will be $355mn. CMAQ plans to use the funding to develop Arqueros, located 35km northeast of La Serena. The mine is expected to produce 1.8mn t/yr of crude ore and 55,000 t/yr of copper concentrates for 15 years. The company aims to start operations in 2026. Nittetsu is to secure all the output from the project. The latest deal follows last month's loan agreement by JBIC and other financial institutes to provide $2.5bn to develop the Centinela copper mine in Chile . Japan relies on all its copper concentrates demand from imports, which has prompted the government to secure long-term and stable supplies of copper resources. The country's strategic energy plan has a target to achieve at least an 80pc self-sufficiency for base metals, including copper, by 2030.

US economic growth slows to 1.6pc in 1Q
US economic growth slows to 1.6pc in 1Q
Houston, 25 April (Argus) — The US economy in the first quarter grew at a 1.6pc annual pace, slower than expected, while a key measure of inflation accelerated. Growth in gross domestic product (GDP) slowed from a 3.4pc annual rate in the fourth quarter, the Bureau of Economic Analysis (BEA) reported on Thursday. The first-quarter growth number, the first of three estimates for the period, compares with analyst forecasts of about a 2.5pc gain. Personal consumption slowed to a 2.5pc annual rate in the first quarter from a 3.3pc pace in the fourth quarter, partly reflecting lower spending on motor vehicles and gasoline and other energy goods. Gross private domestic investment rose by 3.2pc, with residential spending up 13.9pc after a 2.8pc expansion in the fourth quarter. Government spending growth slowed to 1.2pc from 4.6pc. Private inventories fell and imports rose, weighing on growth. The core personal consumption expenditures (PCE) price index, which the Federal Reserve closely follows, rose by 3.7pc following 2pc annual growth in the fourth quarter, although consultancy Pantheon Macroeconomics said revisions to the data should pull the index lower in coming months. The Federal Reserve is widely expected to begin cutting its target lending rate in September following sharp increases in 2022 and early 2023 to fight inflation that surged to a high of 9.1pc in June 2022.
