Innovating for the energy transition
The global shift toward cleaner mobile energy and electrification is reshaping the industry, creating new demands for low-emission technologies and greater sovereignty in critical raw materials. Imerys is supporting this transition by designing advanced mineral-based enabler solutions for sustainable mobility, renewable energy and decarbonization.
Our portfolio for the energy transition spans conductive additives for lithium-ion batteries — including next-generation nanotechnologies — polymer additives for automotive lightweighting, mineral-based filter aids for biofuel purification, and conductive additives for onboard electronics.
We also support the rapidly growing solar and semiconductor markets with high-performance materials that enhance energy storage and conversion technologies.
In parallel, our strategic lithium project EMILI in Beauvoir, France, is set to play a pivotal role in securing Europe’s lithium sovereignty, ensuring a stable and sustainable local supply for the electric vehicle battery market for decades to come.
Key innovations in battery minerals and energy efficient additives
Some of our key innovations for the energy transition include:
C-Nergy® - A range of high-performance conductive carbon blacks and graphites for lithium-ion batteries and fuel cells.
CynerSorb® - A Pioneer-rated mineral filtration absorbents, designed to purify waste feedstocks in biofuel production.
HAR® - A Pioneer-rated range of high aspect ratio talcs for producing lightweight polypropylene for automotive bodywork, reducing vehicle weight and improving fuel efficiency.
ImerFlex HAR® - A high-aspect-ratio talc that can reduce air permeability in tire inner liners by 40%, specifically designed for energy-efficient low rolling resistant (LRR) tires.
Our advanced minerals and strategic lithium projects accelerate the global energy transition, enabling sustainable battery production and low-emission innovation.
Imerys is proud to present the final portrait in our "The Research Behind" video series. Throughout this series, we have offered an unprecedented look into our science and technology process by highlighting the scientists driving our innovation. To conclude our individual expert profiles, we travel to our Graphite & Carbon technology satellite in Kawasaki, Japan, to meet Sanghoon Kim.
On 22 April 2026, French President Emmanuel Macron visited Imerys' Beauvoir kaolin site in Échassières (Allier), dedicated to the EMILI lithium project. The visit was part of a broader government initiative to accelerate France's strategic industrial projects, notably marked by a cabinet meeting held in Montluçon.
We announced today the signature of a ten-year Corporate Power Purchase Agreement (CPPA) with ENGIE, a global leader in low carbon energy and services. This contract will both allow ENGIE to supply annually the grid with 200 GWh per year of renewable electricity in Spain and contribute to the equivalent of 24% of our operations annual electricity needs in Continental Europe.
Cars are getting lighter – reducing CO2 emissions, while maintaining high safety standards, thanks to mineral-infused plastic parts.
