Because The Green Village now has a large number of energy distribution systems, storage systems, and types of energy consumption, significant investments have already been made to facilitate research and product development. With the “The Green Village Digital Energy” project funded by the Kansen voor West programme, we are now able to test solutions that contribute to system integration and smarter energy management.
In an era where increasing digitalisation is crucial for the success of the energy transition, we are happy to provide innovative companies with the environment, infrastructure, and resources to develop and validate products and services that enable energy flexibility. If you are looking for a place to test your data logger, smart algorithms or control systems, please feel free to contact us!
Here are a few examples of flexibility in energy consumption:
- Currently, an electric car starts charging immediately when you plug it into the charging station when you arrive at work or at home. However, this is also a time when the electricity grid is under pressure, and energy prices are high. Since the car often remains stationary for a while before being driven again, it is possible to charge the car at a later time, for example, when the sun is shining or electricity prices are low.
- In fully electrified homes with heat pumps and buffer tanks, better use can be made of available heat. The heat pump can empty the buffer tank in the morning and use cheaper energy in the afternoon to refill it.
- Home batteries can store solar energy for later use. Smart management can ensure that excess solar energy is delivered to the grid during times of higher energy prices and that the battery releases cheaper stored energy in the evening.
At DreamHûs, Borg is testing a prefabricated, underground heat storage system for homes. The system stores excess heat from sustainable energy sources in water for later use.
How does heat storage work? On sunny days, solar collectors on the house heat the water in the tank up to 80 degrees. If there is little sun and wind, the heat buffer provides sustainable energy and hot water for the house. The resident is not dependent on less sustainable energy sources, such as running a heat pump, during those times. Depending on the size of the tank, it can hold heat for several days over an extended period. The Borg buffer tank in the pilot project in Delft has a capacity of approximately 3600 liters and a storage capacity of around 300kWh. Compared to other energy storage systems such as a home battery, Borg offers much more storage space for the same price. The payback period is currently less than ten years, and this will decrease further as energy prices become more variable.
