DENS on TV: Dutch battery technology

DENS in WNL: Nederlandse batterijtechnologie als betrouwbaar alternatief

Chinese technology is everywhere. From phones to cameras, cars to solar panels. That raises an important question: how can organisations make technology choices that are not only cost-effective, but also safe and future-proof?

That topic came up in the TV programme Stand van Nederland: Wereld op Scherp, where DENS shared real-world insights into battery storage developed and built in the Netherlands.

Looking closer at technology choices

In the programme, several examples were given of organisations paying closer attention to where their technology comes from. The City of Amsterdam is replacing certain cameras. Water boards are making stricter demands on suppliers during new tenders. The common theme: more and more parties want to know who is behind the technology they rely on, and what that means for continuity and security.

China is a major producer of technology. That ensures wide availability and competitive prices. At the same time, many European organisations are searching for a better balance between price, reliability and safety. That balance starts with transparency about hardware, software and updates.

As DENS co-founder Tijn Swinkels explained during the broadcast:

“A battery is basically a giant power bank. You charge it at a place with plenty of electricity, such as a solar farm or a wind park. Then you take it to the site where it’s needed, for example to power up an excavator.”

Battery technology from Helmond

From its base in Helmond, DENS builds mobile battery systems for energy storage. These systems provide charging for electric equipment on construction sites, help manage peak demand in areas with grid congestion, or deliver temporary power for projects and events. A Powerhub can be charged where renewable power is abundant and deployed wherever extra capacity is required. The result: less stress on the grid and days of emission-free work on location.

As Swinkels put it in the programme, “The battery is a big power bank. You charge it where you can, and you use it where you must.”

Practical applications

DENS Powerhubs are already in use at large infrastructure projects, including Amsterdam Centraal and Schiphol Airport. In these environments, working emission-free is not only valuable but often mandatory. Mobile storage makes it possible to quickly set up charging infrastructure, absorb demand peaks, and keep projects running even when the grid is full. For construction, logistics, industry and events this means less noise, less pollution and more control over planning.

Making a conscious choice

Choosing the right battery system is not about fear. It is about keeping projects running smoothly, keeping control of your own data, and ensuring that service is always available. Key factors are modular design, clear separation between battery, inverter, cooling and energy management, transparent control systems, secure and where needed local updates, and proven safety standards. With European-made control, transparent software and solid support, projects can operate cleanly, quietly and reliably today and tomorrow.
