Group14 Technologies has secured €150 million in additional funding to support the development of a new silicon battery materials manufacturing facility in Sagunto, Spain, strengthening its European production capabilities and global supply-chain network.
Announced on 29 October 2026, the Series D funding extension brings the company’s total financing under the round to more than $665 million.
The investment will support the development of Group14’s fourth Battery Active Materials facility, BAM-4, which will manufacture the company’s SCC55 silicon-carbon battery material.
The new site will initially provide capacity equivalent to 10 gigawatt-hours (GWh) of battery production, supporting growing demand for advanced battery materials across automotive, aerospace, consumer electronics and industrial markets.
Expanding European manufacturing capacity
The planned facility in Sagunto will establish Group14’s first industrial-scale manufacturing operation in Europe.
Construction is expected to begin in 2028, positioning the company closer to European automotive manufacturers and battery production facilities.
The investment forms part of Group14’s strategy to establish regional manufacturing capabilities and strengthen the availability of critical battery materials.
Once the planned expansion is operational, Group14 expects its global manufacturing network to provide a combined 40 GWh of near-term production capacity.
This will include its BAM-3 facility in Sangju, South Korea, which is already operating and increasing production, and its BAM-2 facility in Moses Lake, Washington, where manufacturing is expected to begin in the first half of 2027.
Supporting next-generation battery technology
Group14 specialises in silicon-carbon battery materials designed to improve the performance of lithium-ion batteries.
Its SCC55 material is intended to support applications requiring high energy density and faster charging, including electric vehicles, drones, consumer electronics and emerging aerospace technologies.
By establishing additional manufacturing capacity in Europe, Group14 aims to improve access to advanced battery materials while reducing geographical supply-chain dependencies.
Rick Luebbe, Chief Executive Officer and Co-Founder of Group14 Technologies, said the company’s expansion strategy is focused on locating battery material production closer to major customer markets.
The Spanish development will support this approach by establishing manufacturing capacity near European automotive and battery industry supply chains.
Creating jobs and strengthening supply chains
The development is expected to support approximately 200 jobs during construction, with between 150 and 200 permanent positions anticipated once operations begin.
Group14’s latest funding was provided by a new investor, whose identity has not been disclosed.
The company said the investment will also support its wider international expansion as demand increases for advanced energy storage materials.
Alongside its planned Spanish operations, Group14 continues to develop manufacturing capacity across the United States and South Korea.
The investment represents a significant step in expanding Europe’s advanced battery materials manufacturing capabilities, supporting regional supply chains and the development of next-generation energy storage technologies.
