About DENS
Technology
Engineering clean power beyond the grid
DENS develops and produces modular energy systems that make clean power available where and when it is needed. Its portfolio includes Powerhub mobile battery systems, Gridhub stationary battery systems, integrated battery modules for electric vehicles and machines, and alternative fuel generators. These solutions are designed for applications where the electricity grid is insufficient, unavailable or under pressure, such as construction sites, infrastructure projects, events, temporary charging hubs and industrial operations.
A distinctive element in DENS’ technology is Hydrozine: a liquid organic hydrogen carrier, also known as formic acid. Hydrozine can store hydrogen in liquid form and can be converted into electricity through DENS’ generator technology, enabling emission-free power generation without harmful local emissions. DENS designs its systems in a modular and scalable way, allowing customers to combine batteries, charging capacity and clean generation depending on their power needs. This makes the technology suitable for both mobile and stationary use cases.
Talent
Build the future of clean energy
Working at DENS means contributing directly to one of today’s most urgent challenges: making clean, reliable energy available in the real world. The company offers an innovative technical environment for professionals who want to work on battery systems, power electronics, embedded software, mechanical engineering, energy management, service, operations and product development.
DENS operates at the intersection of hardware, software, sustainability and high-tech manufacturing. International talent can expect a hands-on scale-up environment, where engineering decisions quickly translate into products used on construction sites, in infrastructure projects and in other demanding applications. The team works on practical solutions with visible impact: reducing emissions, solving grid-related challenges and enabling the electrification of heavy equipment.
“At DENS, you don’t just work on technology, you see your work powering real projects in the energy transition.”
Societal impact
Accelerating the shift from diesel to clean power
DENS contributes to the energy transition by making emission-free power available in places where traditional diesel generators are still widely used. Its battery systems help reduce local emissions such as nitrogen oxides, particulate matter and fossil CO₂, especially in sectors where electrification is challenging, including construction, infrastructure and temporary power supply.
The company’s solutions also address a growing societal challenge: grid congestion. By storing, buffering and delivering power locally, DENS systems can support projects and critical operations that need more energy than the existing grid connection can provide. This helps companies continue their operations while moving towards cleaner and more flexible energy use. DENS’ technology is already applied in real-world projects, from emission-free construction sites to battery systems for high-demand locations such as stadium environments and airside operations.
Role in Brainport
Turning deep-tech energy innovation into real-world impact
DENS is a strong example of the Brainport way of working: combining deep technology, entrepreneurship and practical collaboration to solve complex societal challenges. Based in Helmond, close to Eindhoven’s high-tech ecosystem, DENS builds on regional strengths in engineering, mobility, manufacturing, energy systems and applied innovation. The company originated from the ecosystem around Eindhoven University of Technology and has grown into a technology company that develops and produces energy solutions for demanding markets.
Its Brainport Factor lies in the combination of bold innovation and hands-on execution. DENS does not only develop promising clean-energy concepts; it turns them into robust products that can be used on construction sites, in critical infrastructure, at events and in industrial applications. This practical, collaborative and impact-driven mindset makes DENS attractive for international professionals who want to contribute to technology that is engineered in Brainport and deployed in the real world.
