Nickel Reserves in Indonesia at Risk of Depletion Within 11 Years: Investment, Environmental, and Tech Challenges in 2026 — BRIN, ITB, and Industry Push for Battery Ecosystem and Sustainable Solutions

Indonesia’s nickel reserves are projected to be depleted within 11 years if current extraction rates continue, according to recent assessments from the Geological Agency. This warning comes as the country maintains its position as the world’s largest nickel producer, with output reaching 2.2 million tons in 2023 and accounting for 22% of national emissions from the energy and industrial sectors. The projected timeline varies by ore grade: reserves with nickel grades of 1.7% or higher are expected to be exhausted by 2036, while lower-grade reserves below 1.7% could last until 2056, assuming no new discoveries or changes in production rates.

The Indonesian government has responded to these challenges with a dual strategy aimed at both stabilizing markets and reducing environmental impact. On December 19, 2025, Minister of Energy and Mineral Resources Bahlil Lahadalia confirmed plans to cut nickel production in 2026 to support global prices and increase government revenue, while also cracking down on environmentally harmful mining practices. This move is intended to address market volatility caused by oversupply and to extend the lifespan of existing reserves through more disciplined extraction.

Simultaneously, Indonesia is pursuing a comprehensive decarbonization agenda for its nickel industry. A government roadmap released in January 2026 targets an 81% reduction in emissions from nickel production by 2045, aligned with national climate goals. Current production remains heavily reliant on coal-fired power, with each ton of nickel produced generating an average of 93 tons of carbon dioxide equivalent. The initiative aims to shift toward cleaner energy sources in processing, which would not only reduce environmental harm but also improve Indonesia’s competitiveness in the growing global market for electric vehicle batteries and other low-carbon technologies.

Despite these efforts, analysts warn that Indonesia’s resource-based industrialization model may limit its ability to fully develop a domestic clean technology value chain. While the country has successfully expanded nickel mining and processing, experts note that a focus on raw material export and mid-tier processing hinders progress toward higher-value manufacturing such as battery production and electric vehicle assembly. This dynamic has been described as “nickel nationalism,” where state control over resources prioritizes short-term revenue over long-term industrial upgrading.

To extend reserve life, the government is encouraging increased exploration in brownfield areas, detailed geological mapping of ultrabasic rock zones, and investment in remaining underexplored regions. These efforts aim to discover new deposits or upgrade the classification of existing resources. However, without significant new finds or technological advances in recovery, the current trajectory suggests that Indonesia’s nickel wealth — a cornerstone of its export economy — will face increasing pressure over the next decade.

The situation underscores the tension between maximizing short-term economic gains from natural resources and ensuring sustainable, long-term development. As global demand for nickel is projected to grow — potentially doubling by 2050 under International Energy Agency net-zero scenarios — Indonesia’s ability to manage its reserves responsibly will determine whether it can transition from a raw material supplier to a leader in the clean energy supply chain.
