Silicon anodes from Groningen: US start-up GDI builds demonstration factory to cut China dependency
Haskoning selected by GDI for battery demonstration factory in Farmsum
Advertisement
The American start-up Graphenix Development Inc. (GDI) is located in Farmsum, in the province of Groningen. The company will develop silicon anodes here, an important part for Li-Ion batteries for which Europe is currently still highly dependent on China. Haskoning supports GDI and takes care of the project management for the realization of the first GDI demonstration factory in Farmsum.
GDI develops anodes - electrode in a battery or other electrical system where a chemical reaction takes place - that can store more energy, charge faster and make Chinese components and raw materials unnecessary. This makes an important contribution to the transition towards the next generation of batteries and strategic autonomy of this value chain in a geopolitically uncertain climate. These innovative battery components are essential for applications in defence, medical equipment and e-mobility.
The Road to Groningen
Thanks to the strong technology and innovation power surrounding the technology cluster in Eindhoven, GDI decided in 2021 to further expand its activities in the Netherlands. For the development of a demonstration factory, the company received a lot of support from the Northern Development Company (NOM) and Groningen Seaports in the Northern Netherlands and GDI wants to use the years of regional knowledge and infrastructure in the energy sector in Groningen.
To accelerate the rollout of the pilot and take advantage of Haskoning's regional reputation, GDI has asked Haskoning to provide support from its regional involvement and expertise in the industry. For GDI, Haskoning has provided design, engineering, safety analysis and support for construction. In doing so, the company contributes to the successful realization of the factory, suitable within the regional context and fully in accordance with applicable laws and regulations.
Innovative Battery Technology
Europe aims to become less dependent on graphite anode factories in China. Although graphite remains the dominant technology for the time being, silicon anodes are considered the important next step in the development of the next generation of batteries. A Plasma-Enhanced Chemical Vapor Deposition (PECVD) system is installed in the Groningen demonstration factory. This specialized production system is used for the production of semiconductors and the application of thin film coatings.
GDI develops 100% silicon anodes for battery applications and is a leading party worldwide with more than 46 internationally recognized patents. Silicon is a promising alternative to the traditional graphite anodes currently used in batteries. The material can store about 10 times more lithium than graphite, giving batteries a higher energy density.
A Scalable Factory Concept
The aim of the project is to design and build a pilot and demonstration factory for the production of silicon anodom samples for future customers and process development / optimization. The project is currently in the preparatory phase of construction. The pilot plant is expected to be operational early next year.
GDI deliberately starts on a small scale, but high in the value chain. In the demonstration factory, samples are produced for potential customers and process development and –optimization for new high-quality battery types is carried out. The company focuses on high-quality technology development and not on mass production.
GDI expects to scale up to a factory with a capacity of approximately 50 megawatt hours within the EU within a few years. The investors involved include a.o. InnoEnergy, the Northern Development Agency (NOM), Impact Capital of New York, New York Ventures, Helios Climate Ventures and W.L. Gore.
Boost for Groningen and the High-Tech Manufacturing Sector
The arrival of the GDI factory to Farmsum is an important impulse for both Groningen and the Dutch high-tech industry. With GDI, the Northern Netherlands brings high-quality technological production to the region, with a dual-use key role in achieving climate objectives, as well as in developing strategic autonomy in raw materials and defence technology.
The company's location strengthens Groningen's position as an important center for next-generation battery components and contributes to the development of a strategic European battery value chain.
On September 25, a meeting will take place in Farmsum with the management of GDI from the United States and the main stakeholders, including Groningen Seaports, the NOM, the municipality of Eemsdelta, the province of Groningen and Haskoning. During this meeting, the progress of the project and the future growth plans within the region will be discussed.
