Alternatives to generators

Traditional diesel generators are under increasing pressure. They cause a lot of CO₂ emissions, nitrogen and noise pollution, while the construction and industrial sectors need to become more sustainable more quickly. Therefore, there is a growing demand for alternatives to generators that are quiet, clean and cost-efficient. New technologies such as battery systems and hydrogen solutions make it possible to provide reliable and emission-free power everywhere.

Why look for an alternative to aggregates?

Diesel generators have been the standard for many years, but they fit today's requirements less and less. Laws and regulations surrounding emission-free construction are becoming stricter and clients are setting higher sustainability criteria. Moreover, the use of fossil fuels involves high costs and risks. An emission-free power supply not only offers a healthier and quieter alternative, but also helps to avoid delays and fines due to environmental requirements. This dovetails perfectly with the developments around zero-emission construction sites.

Battery systems as quiet and clean alternative

Battery systems are the sustainable alternative to generators. They are completely emission-free, quiet in operation and easy to install thanks to plug-and-play solutions. Think robust battery containers that store large amounts of energy and can be used flexibly. For mobile applications, compact systems are available that provide instant power where needed. Read more about the benefits of this flexible solution in our mobile battery blog.

Innovative sustainable alternatives

As the energy transition progresses, new opportunities to replace generators are emerging. Hydrogen generators offer a solution for projects with high energy demands, such as large construction sites. Hybrid systems are also gaining ground, combining a battery with renewable sources such as solar panels. These so-called solar generators charge a battery, allowing you to work completely emission-free. In all cases, the less dependence on fossil fuels, the better for the environment and cost development.

The advantages of battery solutions over generators

The main advantage of battery systems is that they are emission-free and quiet. They are also more energy efficient and easily scalable, making them suitable for both small- and large-scale projects. They are also attractive financially: lower fuel costs, less maintenance and no risk of fines due to violation of emission standards. Want to know more about how smart storage works?
