U.S. automotive giant General Motors (GM) has announced an investment in U.S. startup Peak Energy and plans to advance the commercialization of sodium-ion batteries, primarily for energy storage systems (ESS), with deployment targeted after 2029. This marks the first meaningful entry of a non-Chinese automaker into the field and is prompting Korea’s battery industry to incorporate sodium-ion technology into its strategic priorities, even as it accelerates efforts to catch up in LFP. Unlike ternary batteries (NCM/NCA) and LFP, which rely on lithium, sodium-ion batteries use more abundant and lower-cost sodium as a substitute, offering advantages such as greater supply chain stability, better low-temperature performance, and enhanced safety—making them particularly suitable for large-scale energy storage applications. At the same time, increased volatility in lithium prices has further strengthened the cost competitiveness of sodium-ion batteries. Korean players including LG Energy Solution, Samsung SDI, and SK On have already accelerated their efforts, aiming to advance sample production or commercialization around 2027. Overall, GM’s entry signals that a technology pathway previously dominated by Chinese companies is becoming globalized, and it is likely to push Korean battery manufacturers to accelerate adjustments to their technology and product portfolios.

Since 2017, Vietnam’s solar market has grown rapidly under strong policy support, especially feed-in tariff incentives. This drove fast capacity expansion but also exposed grid constraints as development outpaced transmission infrastructure. As subsidies gradually phased out, market logic shifted from policy-driven growth to energy security and system stability.

From June 3 to June 5, Indonesia Critical Minerals 2026 was held at the Pullman Jakarta Central Park in Jakarta, Indonesia. The conference was organized by Shanghai Metals Market (SMM) and co-organized by the Indonesia Nickel Miners Association (APNI) , the Ministry of Foreign Affairs of the Republic of Indonesia , the National Economic Council of Indonesia , and MMR , in a strategic partnership with the Jakarta Futures Exchange . The conference featured six dedicated forums: the main forum, the nickel and cobalt forum, the tin forum, the coal & energy transition forum, the aluminum forum, and dedicated sub-forums, attracting 3,500+ attendees from 45 countries and regions worldwide, featuring more than 120+ speakers sharing insights on market prices, supply-demand patterns, industry policies, low-carbon development, and ESG development, etc. Conference Background As the largest economy in Southeast Asia, Indonesia is accelerating its energy transition and green, low-carbon development, presenting strategic opportunities for the PV and energy storage industry. To realize its 2060 carbon neutrality vision, the Indonesian government has issued a national energy plan that explicitly sets a target of 100 GW of PV installations by 2030. At the same time, Indonesia's resource-based industries such as nickel ore are concentrated, and mining enterprises face increasingly stringent ESG compliance requirements and pressure for sustainable transformation. Coupled with the challenges of accelerating domestic industrialization and persistently tight power supply, equipping mines with PV and energy storage systems has become a core pathway to addressing power shortages, reducing carbon emissions, and controlling energy costs. Market demand is being rapidly unleashed, creating vast opportunities for future industrial cooperation. Against this backdrop, SMM has organized a Coal & Energy Transition Forum at this conference, aiming to gather industry elites and jointly explore new opportunities for PV+ESS development in Indonesia. 》Click to view the conference live photo coverage June 4: Coal & Energy Transition Forum Keynote Speeches Keynote Speech: The Future of Renewable Energy for Mining Contractors in Indonesia Guest Speaker: Bambang Tjahjono, Executive Director of ASPINDO Panel Discussion: The Indonesia 2060 Net-Zero Roadmap: The Role and Transition Pathway for the Mining Sector Moderator: Verena Streitferdt, Director, Tri Hita Consulting Panelists: Alfonsius Ariawan, Mining & Metals Lead, Indonesia, dss+ Yan Yan Muhammad Achdiansyah, Innovative Project Manager for Asia Pacific, HDF Energy Ardhi Ishak, Chairman of Industry Relations & Industry Associations, PERHAPI (Association of Indonesian Mining Professionals) Keynote Speech: Banking on the Transition: Sustainable Finance Solutions for Indonesia’s Mining and Energy Sector Guest Speaker: Dendi Ramdani, Vice President for Industry and Regional Research, PT Bank Mandiri (Persero) Tbk.

Mine decarbonization cannot be achieved solely through carbon disclosure, carbon offsets, or green procurement. Daily production activities such as transportation and turnaround, captive power supply, crushing and grinding, mine ventilation, and process electricity are the core carriers of carbon emissions. The core challenge for the industry today is to steadily reduce carbon emission intensity against a backdrop of growing demand for minerals. This requires a systematic restructuring of the mine’s overall energy system, rather than simply replacing fuels for individual equipment. Diesel-powered transport is the key battleground for carbon reduction in mines Various types of mobile equipment are the key targets for carbon emission monitoring. The average annual fuel consumption of a single mining truck is close to one million liters. For open-pit mines, fuel consumption is closely linked to haul distance, road gradient, payload, dispatch management, and vehicle idling. Therefore, the transport phase becomes the optimal breakthrough point that balances carbon reduction and production efficiency. The electrification of mining trucks is not a technical bottleneck; the real key lies in whether the supporting core infrastructure, such as charging and energy storage, can enable the equipment to operate at full capacity and ensure that production is not affected. The global fleet of large mining haul trucks numbers about 28,000 units, and is still predominantly diesel-powered. According to RMI estimates, the average annual diesel consumption of a single truck reaches 900,000 liters; energy consumption by haul vehicles accounts for 30%–50% of total mine energy use, corresponding to annual CO2 emissions from the global fleet of approximately 68 million mt.

2026 China Central International Power Transformer Export Expo 2026 China Central International Power Transformer Export Expo Concurrently held: The 8th China (Zhengzhou) International New-type Power and Smart Energy Industry Exhibition August 15-17, 2026, Central China International Convention and Exhibition Center (Airport Area) Annual Central China Power and Electrical Industry Development Conference Estimated exhibition data: 18 countries and regions 600+ exhibiting brands 300+ media coverage 20 forum events 40,000 m² exhibition area 50,000 visitors Co-organizers: Henan Electrical Equipment Industry Association Beijing Aibo International Exhibition Co., Ltd. Executing Unit: Beijing Aibo International Exhibition Co., Ltd. Title Sponsor: Henan Senyuan Electric Co., Ltd. Official Website: http://byq.aiboexpo.com ※ Exhibition Overview: Currently, 'carbon neutrality' has become a global consensus. Achieving carbon peak and carbon neutrality is a solemn commitment China has made to the world and a broad and profound economic and social transformation. Realizing clean and zero-carbon energy is a crucial guarantee for carbon neutrality. The development and maturation of the new-type power industry are of great significance for accelerating the construction of a new power system dominated by new energy. In recent years, supported by a series of national policies, global renewable energy industries such as PV, wind power, hydropower, new-type energy storage, charging facilities, and hydrogen energy have achieved rapid development. With new breakthroughs in next-generation technologies and equipment, the future new energy market holds limitless prospects. At the 2024 Bosch Connected World conference, the world's richest man Elon Musk predicted that the rapid development of AI and EVs would lead to a severe shortage of transformers. Today, this prediction has become a reality. Amid this global 'transformer shortage', the latest data from China's General Administration of Customs shows: in 2025, China's transformer export value reached 64.6 billion yuan, a YoY surge of 36%, with the average unit price exceeding 205,000 yuan, a rise of 33%. Even more astonishing—orders for high-end ultra-high voltage and data center-dedicated transformers have been scheduled into 2027, with some stretching into 2028! The global transformer shortage is the inevitable result of multiple contemporary factors overlapping. From an infrastructure perspective, the power systems in Europe and the US are undergoing a 'major overhaul'. A Goldman Sachs report from September 2025 pointed out that most of Europe's grid infrastructure has been in operation for 40-50 years, and in the US, 31% of transmission equipment and 46% of distribution facilities are past their service life. To this end, the EU plans to invest €1.2 trillion over the next decade to upgrade its power grid, and the US also announced $1.1 trillion over five years for the power sector. As core equipment for power grid upgrades, transformers have naturally become a focal point of demand. Amid the global transition toward green and low-carbon development, the construction of green energy power plants such as PV and wind power has further lifted transformer demand. The international energy industry analysis firm “Allied Market” forecast that the global transformer market size will reach $103 billion in 2031, Henan is located in central China and has long been known as the “heartland of Kyushu and the thoroughfare of ten provinces,” serving as an important transportation hub in China that connects east and west and links north and south. Developing a hub economy is a key pillar for integrating into the new development paradigm. “In recent years, our province has leveraged its transportation and location advantages to continuously strengthen the hub economy. Seizing the opportunity presented by the development of a unified national market, we have built a comprehensive ‘rice + well + people’ transportation corridor and initially formed a broad multimodal transport landscape integrating and connecting airports, inland ports, highway ports, high-speed rail ports, and ports of entry. It has become a logistics corridor hub that connects at home and abroad and radiates across the east, central, and west. Trading globally, the hub advantage is gradually being transformed into a competitive edge for development. Leveraging Henan’s status as a major province in China in terms of population, agriculture, industry, and energy consumption, its transportation and geographic advantages are driving global power grid upgrades, with transformers playing a crucial role in building a new-type power system. To rapidly and accurately connect sellers and buyers and help enterprises expand broader markets in and outside China, the “2026 China · Central and Western China International Power Transformer Export Expo,” jointly organized by the Henan Electrical Industry Association and Beijing Aibo International Exhibition Co., Ltd., is scheduled to be held on August 15-17, 2026 at Zhongyuan International Convention and Exhibition Center, Zhengzhou Airport Economy Zone, concurrently with the “8th China (Zhengzhou) International New-Type Power and Smart Energy Industry Exhibition.” This exhibition is expected to cover 40,000㎡, attracting more than 600 brand exhibitors from around the world to make a concentrated appearance in central China, with over 50,000 visits expected from professional visitors and buyers. We sincerely invite transformer producers, manufacturers, and related supporting suppliers from in and outside China to gather in central China and share this grand industry event! As one of China’s 12 highest-level international comprehensive transportation hubs and one of the country’s six airport-type national logistics hubs, Zhengzhou is a comprehensive hub city integrating highways, railways, aviation, power, and communications. It enjoys uniquely advantageous geographic conditions. With Zhengzhou as the center, a two-hour aviation circle covers 92% of China’s population, 94% of its total economic output, and 98% of its foreign trade share. Against the backdrop of the current dual-circulation development model and domestic demand boost, Zhengzhou’s market radiation advantage nationwide will become even more prominent. Henan has a solid industrial foundation and a complete industrial supporting system, highly aligned with the development needs of the new energy industry. It can better promote deep integrated development across the upstream and downstream industry chain of new energy enterprises, achieve resource sharing and complementary advantages, and jointly drive coordinated development of the industry. Zhengzhou Airport Economy Zone Comprehensive Experimental Zone, known as the “Central China Special Zone,” is currently the only national-level aviation economy development pilot zone approved by the State Council. The Airport Economy Zone closely focuses on five major strategic positioning goals: the “Air Silk Road” pilot zone, the “National Airport Economy Experimental Zone,” the “core growth pole of the Central Plains Economic Zone and the Zhengzhou Metropolitan Area,” a “modernized, internationalized, world-class logistics hub,” and the “Central China Special Zone”; and deepens the development of five major centers: an international advanced manufacturing center, international trade center, international transportation and logistics center, international creative fashion center, and international innovation talent center. The Airport Economy Zone has become a growth pole of great strategic value for Zhengzhou’s development and a high ground for opening up across the province. ※Key Invitations Target Audience: Power, petroleum, chemicals, metallurgy, steel, cement, coal, textiles, transportation, electronics, communications, environmental protection, transport, machinery, turnkey equipment suppliers, traders, etc. Real estate developers, construction contractors, decoration and renovation companies, architects, designers, engineers, importers and exporters, wholesalers, distributors, manufacturers, retailers, buildings, property management institutions, and industry end-users (such as hospitals, schools, government agencies, hotels, shopping malls, etc.).

Recently, the largest battery energy storage project in Hungary, invested and constructed by Greenvolt Power, was officially put into operation, and an inauguration ceremony was held at the project site. The project has a scale of 99.8MW/288.6MWh, with BYD Energy Storage providing 288.6MWh of its Cube Battery Energy Storage System. Following its operation, this project will significantly enhance the regulation capability and power supply reliability of the local grid, support the large-scale grid integration of renewable energy in Hungary and the Central and Eastern European region, and accelerate the green transformation of the local energy structure.

Recently, the methanol-hydrogen backup smart microgrid on Dadaosha Island, Panyu District, Guangzhou, completed commissioning and was successfully put into operation, with equipment running in a stable state. This marks the first on-site application of methanol reforming hydrogen production and power generation technology in an urban island distribution network scenario in Guangzhou. It not only opens a green pathway for ensuring residential power supply during emergencies such as extreme weather and disasters, but also creates a replicable and scalable practical model for emergency power supply work in islands, urban villages, and central urban areas within the Guangdong-Hong Kong-Macao Greater Bay Area. This methanol-hydrogen backup power supply was independently developed and built by the Guangzhou Power Supply Bureau of Guangdong Power Grid Company. The overall system comprises three core modules: methanol reforming hydrogen production , fuel cell power generation, and lithium battery energy storage buffering. It can steadily provide 1,000 kWh of continuous power supply and quickly restore power when the main grid fails. According to relevant technical personnel, the system uses methanol as a hydrogen storage carrier. It produces hydrogen on-site through catalytic reforming technology for immediate use, completely avoiding the safety risks associated with high-pressure hydrogen storage and transportation. The entire process from methanol solution refueling and unit startup heating to full-load operation is automated, and it can also flexibly adapt to dynamic changes in electricity loads. Compared with traditional diesel generator sets, this equipment offers distinct advantages: the cost per unit of power generation drops by approximately 50%, operating noise is significantly reduced, and carbon emissions are cut by over 40%, demonstrating a very prominent green and energy-saving profile. Located at the Pearl River estuary, Dadaosha Island and Guanlong Island primarily rely on agricultural production, with fish ponds, flower planting bases, and agro-cultural tourism projects scattered across them, imposing stringent requirements on power supply stability. Previously, the two islands depended on a single overhead line across the river for power, with no backup supply channel, resulting in a relatively weak grid structure. Coupled with the geographical feature of being surrounded by water, line patrols and emergency repairs during severe weather or at night were challenging, and power restoration after outages took a considerable amount of time. To address the challenge of securing power supply for islands, the Guangzhou Power Supply Bureau planned and deployed four independent yet mutually cooperative microgrids across the two islands. This initiative established the first megacity island microgrid cluster within China Southern Power Grid that achieves coordinated and partitioned regulation and dynamic islanding control across the main grid, distribution network, and microgrid. Multi-grid coordination and linkage are also central to the stable operation of this new-type power grid system. According to staff introduction, the four microgrids can operate either independently or complement each other through networking for combined power supply. During normal main grid operation, the microgrids can participate in power dispatch and peak shaving and valley filling, reducing grid energy consumption. Once an external grid fault occurs, the system can switch to islanded operation mode within milliseconds, rapidly restoring power supply to the area and ensuring that residential living and agricultural production are unaffected. On April 22 this year, an off-grid field test was also conducted. The test simulated a transformer fault and disconnection from the main grid. The methanol-hydrogen backup power supply quickly connected to the low-voltage grid, with an imperceptible switching process. All electrical equipment for the island’s 94 user households returned to normal operation, and neither irrigation nor residential electricity was interrupted. One hour later, the main grid restored power, and the equipment automatically switched to standby mode. The fuel cell simultaneously recharged the ESS battery, remaining on standby for subsequent emergency needs. Reliable power support also lays a solid foundation for the development of the local agro-cultural tourism industry. A relevant person in charge of a large-scale cultural tourism camp on the island stated that after the microgrid’s operation, various electricity consumption scenarios—such as fish pond farming, amusement facilities, and RV charging—have all received stable support. Currently, this set of methanol hydrogen production and power generation equipment has been connected to the Guangzhou urban distribution network intelligent management and control platform. Future implementations will include unattended operation, remote control, and autonomous fault diagnosis functions. The main part of the project for the remaining three microgrids has been completed, and equipment joint commissioning is currently underway. They are planned for full deployment by month-end June to fully guarantee regional electricity demand during the summer peak and support agricultural and cultural tourism projects.
