Jyderup School

Jyderup is a small railway town situated in the northwestern part of Zealand, within Holbæk municipality. It has a population of around 4300 people and a significant landmark of the town is Jyderup school. Set in a peaceful natural setting and steeped in history, the school serves as a stable reference point in the area. With a capacity of up to 450 students and 50 staff, the school is committed to providing a conducive environment that promotes learning and growth.

As a close sparring partner, Jyderup school has Holbæk municipality. Holbæk municipality has set an ambitious goal of being among the municipalities in the country with the lowest emissions of greenhouse gases. This has already resulted in Jyderup school being supplied with solar panels on the roof of the school, but now Holbæk municipality has taken the next step.

A collaboration with the Aarhus-based company VisBlue has been agreed to, and this has resulted in Jyderup School now being further supplied with a redox flow battery which aims to store excess solar energy from the school's solar cells so that this energy can be used at other times.

Before the collaboration with VisBlue, Jyderup School had a utilisation of 27% of their solar cells, but with the connection of the battery, this is now up to 40%. The utilisation of solar energy is thereby significantly optimised, which will result in an annual saving of DKK 60,000 in the municipality. In addition, the measure must also be said to be a partial commitment in becoming a green municipality. Holbæk municipality has plans for a CO2 reduction of 70% by 2030, and the investment in a VisBlue redox flow battery must be claimed to be a step in the right direction. With the battery's optimisation of the utilisation of the school's solar cells, Holbæk municipality now manages to save 4,100 kg of CO2 annually.

Holbæk municipality must in this way be said to be a municipality that commits to its goals. The collaboration between Holbæk municipality and VisBlue is an excellent example of how a green profiling can not only be good for the climate but also for operating costs. With the battery, the annual savings on the electricity bill will also mean that the battery has paid for itself in 7-8 years. With a minimum lifespan of 20 years, this will mean a total saving of up to DKK 800,000 over the life of the battery.

It pays to go green.
