Biking is not only good for your health, but it also ensures that the environment is not burdened. At least that is what you would think, but did you know that quite a bit of nitrogen and also CO2 is emitted during the construction of bike paths? This is due in part to emissions from the supply and disposal, as well as the materials. Therefore, when constructing new bike paths or renovating existing paths, we actively look at how this can be reduced.

Such was the case in Speuld in the municipality of Ermelo (Gelderland). The bicycle path through the nature reserve here was in dire need of replacement, but because part of it also lies in a protected Natura 2000 area, additional stringent requirements came into play. For the so-called “streetprint,” a technique that creates a natural pattern in asphalt in a sustainable manner, a pattern was chosen that would significantly increase diesel consumption. Anything but optimal conditions for a “green bike path,” in other words.
Full-service infrastructure partner Van Gelder, however, dared the challenge. It therefore started a conversation with Volta Energy, because how could this ‘street printer’, a device that normally runs on a diesel generator, be more sustainable? At Volta Energy, we of course knew what to do and delivered a 45 kVA solar generator. This sustainable generator was used over a period of 35 days to power the street printer.
Thanks to this generator, instead of the 1428 liters of diesel that a conventional diesel generator would have used, only 79.2 liters were used. Moreover, 6.2 kg less nitrogen (NOx) was emitted and over 4585 less CO2. In other words, a huge savings!
The 45 kVA Volta Solar Generator consumed 181 kWh of energy over 35 days. With the generation of energy from the sun, the PV panels were able to sustainably realize more than half of this (99 kWh). Combined with the battery present, this enabled Van Gelder to achieve a 97% savings in running time. And that in the months of October and November, not an ideal period for solar energy!
At the bottom line, even in suboptimal conditions, the cost of the Solar Generator was only €11.60 more expensive than the cost of a conventional generator and a whopping €202.60 cheaper than a HVA B100 biodiesel generator! Therefore, we can definitely state that if this project had been carried out in summer or spring, the Solar Aggregate is not only a much more sustainable, but also cheaper solution for street printers.
The power generators come in different sizes - from 6 kVA to 120 kVA - so that all construction sites and events can be supplied with renewable energy on site. Our bio-solar-hybrid generators are more sustainable than conventional diesel generators and hybrid diesel-battery generators. When the sun is not shining, our generators automatically switch from solar to battery and then to bio-diesel genset. This way, we make sure you always have power..
