The roots of today’s Greenerity GmbH date back to the 1990s, when initial research and development activities in the field of PEM fuel cells and PEM electrolysis began at Degussa AG’s research site in Hanau.
After several sales and rebrandings of Degussa Group’s precious metals business units, the Belgian materials technology company Umicore S.A. took over the respective operations in 2003.
On July 1, 2006, Umicore, together with the Belgian company Solvay S.A., established the joint venture SolviCore GmbH & Co. KG. The goal was to combine the expertise of both companies in catalyst, membrane, and ionomer technologies to position themselves as a strong partner in the growing fuel cell market.
After nine successful years, SolviCore GmbH & Co. KG — then employing around 40 staff — was acquired in 2015 by the Japanese technology group Toray Industries, Inc., and renamed Greenerity GmbH in early 2016.
Over the past ten years as part of the Toray Group, Greenerity GmbH has grown into a company with three locations in Alzenau (Bavaria) and Hanau (Hesse).
In modern industry, efficient production processes are essential for manufacturing high-quality products quickly and with minimal resource consumption. That’s why our manufacturing operations at each site are precisely tailored to the specific product requirements – ensuring maximum precision and cost-effectiveness.

To meet the steadily growing demand and sustainably expand our production capacities, we have extended our existing manufacturing facility with a modern annex. This investment sends a clear signal of our commitment to growth, innovation, and long-term competitiveness.
The new building extension not only provides additional space for state-of-the-art manufacturing technologies, but also enables more efficient workflows and even more flexible production planning. This strengthens our market position while simultaneously creating new jobs in the region.
This expansion is a key element of our strategic direction – aimed at continuing to meet the growing demands of our customers through quality, reliability, and technological excellence.

With passion and innovative spirit, we are dedicated to researching and developing technologies that drive the energy transition and contribute to the decarbonization of the economy.
In this dynamic environment, our experts combine their skills in interdisciplinary teams – from fundamental research to product and process development, all the way to the testing center. This is how solutions are created that pave the way toward a sustainable future.
We develop innovative solutions for new materials, manufacturing processes, and technologies that enable the efficient use of hydrogen – thereby making an important contribution to reducing CO₂ emissions.
We are driving the continuous advancement of fuel cell and electrolysis technologies to create efficient and sustainable energy solutions – for a climate-friendly future and a reliable energy supply.
Through targeted optimization of performance, long-term stability, reliability, and cost-effectiveness ("Design to Cost"), we develop products that meet the demands of current and future markets – efficient, robust, and competitive.
Through close collaboration across all company divisions, we successfully scale advanced solutions to industrial level – efficiently, practically, and ready for the market.
A key focus of our research and development activities – in close collaboration with our parent company Toray Industries, Inc. – is the integration of hydrocarbon-based membranes. These innovative materials have the potential to replace conventional PFSA membranes and significantly enhance the environmental compatibility of catalyst-coated membranes.
We tackle these technological challenges with extensive internal resources as well as through publicly funded projects – driving sustainable progress in energy technology.
Efficient production processes are crucial in modern industry to manufacture high-quality products quickly and with minimal resource consumption. That’s why our manufacturing workflows at each site are precisely tailored to the specific requirements of the respective products.
Strict adherence to the highest quality standards in production and logistics is a key success factor for us and our partners.
Moreover, through sustainable supplier management, we cultivate long-term business relationships – in alignment with our ecological, social, and ethical principles.
Continuous improvement in close collaboration with our customers, combined with the targeted use of operational excellence initiatives, enables us to consistently enhance processes, develop new capabilities, and promote both personal and professional growth.
In close collaboration with the engineering and technology departments, we develop and standardize chemical and mechanical processes to ensure maximum efficiency and quality in manufacturing.
By implementing lean management principles, we continuously improve workflows in our production and operations areas – enabling streamlined processes, maximum value creation, and sustainable efficiency.
Through effective supplier management, we ensure a stable supply chain and guarantee smooth provisioning – reliable, predictable, and aligned with our quality and sustainability standards.
Our employees are the heart of our company, and we place great importance on creating a supportive and inspiring work environment where everyone can realize their full potential.
We invite you to learn more about our work in these key areas.
