Ethyl Tertiary-butyl Ether Market Report 2026

The ethyl tertiary-butyl ether market size has grown strongly in recent years. It will grow from $6.35 billion in 2025 to $6.89 billion in 2026 at a compound annual growth rate (CAGR) of 8.4%. The growth in the historic period can be attributed to growth of gasoline consumption, adoption of fuel quality regulations, demand for octane enhancement, expansion of ethanol production, refinery blending requirements.

The ethyl tertiary-butyl ether market size is expected to see strong growth in the next few years. It will grow to $9.18 billion in 2030 at a compound annual growth rate (CAGR) of 7.4%. The growth in the forecast period can be attributed to stringent emission norms, demand for cleaner fuels, growth of bio gasoline blends, advancements in etherification technologies, rising automotive fuel efficiency standards. Major trends in the forecast period include rising demand for high octane fuel additives, increasing use of oxygenated fuel components, growing adoption of cleaner burning gasoline blends, expansion of bio fuel and ethanol based additives, higher focus on emission reduction in transportation.

The increase in demand for fuels is expected to propel the growth of the ethyl tertiary-butyl ether market going forward. Fuels are substances that undergo combustion or chemical reactions to release energy for generating heat, producing electricity, powering vehicles, and supporting industrial processes. There is a rise in the demand for fuels due to factors such as economic growth, a rising population, expanding transportation needs, and industrial development. Ethyl tertiary-butyl ether (ETBE) is used in fuels as an octane enhancer, improving engine performance and reducing emissions, thereby contributing to cleaner combustion and meeting environmental regulations. For instance, in September 2024, according to Statistics Canada, a Canada-based government agency, gross sales of gasoline increased to 43.6 billion liters in 2023, up 2.6% from 2022, reflecting a rebound in fuel demand driven by increased motor vehicle registrations, a return to in-office work, and higher domestic travel. Therefore, the increase in demand for fuels is driving the growth of the ethyl tertiary-butyl ether market.

Major companies operating in the ethyl tertiary-butyl ether market are adopting strategic partnerships to expand production capacity, enhance technological capabilities, and strengthen market presence. Strategic collaborations support the growth of the ethyl tertiary-butyl ether market by facilitating joint R&D efforts, improving supply chain efficiency, and accelerating adoption in emerging fuel and chemical industries. For instance, in October 2024, The Energy and Resources Institute (TERI), an India-based independent research organization, partnered with the Asian Clean Fuels Association (ACFA), a Singapore-based association, to examine the role of Ethyl Tertiary-butyl Ether (ETBE) in advancing India’s biofuels program. The initiative aimed to promote cleaner fuel alternatives, enhance fuel efficiency, and reduce vehicular emissions through wider use of ETBE-blended gasoline. This partnership also sought to support policy recommendations and enable knowledge sharing among industry stakeholders to expedite the country’s transition to sustainable fuel solutions.

In May 2024, INEOS Group Limited, a UK-based petrochemicals manufacturer, acquired LyondellBasell’s Ethylene Oxide and Derivatives (EO&D) business for an undisclosed amount. Through this acquisition, INEOS sought to expand its EO&D presence in the U.S., the world’s largest market, and complement its existing ethanolamines facility in Louisiana, thereby enhancing its product portfolio and strengthening its supply chain network. LyondellBasell Industries N.V. is a Netherlands-based chemicals and polymers producer specializing in high-purity ethylene oxide and related derivatives.
