City of Dresden (Germany)
Dresden
The municipality of Dresden aimed to cover new energy-demand and sustainability goals for its former stables refurbished to office-building. Since 2019, EnerTwin is installed in a shared heating room for a 3 level office building. In this set-up, the Solution is connected to a buffer vessel, which itself is connected to the main heating circuit of the building. With an annual running time of around 5,000 hours, the electricity produced averages 11,000 to 15,000 kWh yearly.
The solution offers a return on investment (ROI) in less than 6 years, while also significantly reducing environmental impact. It cuts CO₂ and NOx emissions by 9.5 tons annually, contributing to cleaner air and a more sustainable future.
These situations especially occur in historical buildings which form the centre of many beautiful European cities and villages. Apart from giving the necessary heat to the users of a building, it also provides locally generated electricity at unmatched efficiency (94%), also by using clean fuels such as biomethane, green gas and hydrogen. The EnerTwin is a very small domestic power plant where a boiler and an electricity generator are combined in a single durable device. The heart of the EnerTwin is a microturbine that drives a generator. Microturbines can be easily installed, have a very long life and require very little maintenance. EnerTwin is "micro-cogeneration plus": it will keep our inner cities livable for the next generations, at affordable cost.
