Energiedamwand Nederland integrates heat‑exchange collectors into new or existing steel damwalls to extract thermal energy from surface water, providing low‑carbon heating and cooling for adjacent buildings. The closed‑loop system circulates a water‑glycol mixture to a high‑efficiency water‑water heat pump, delivering heat or cold to single facilities or low‑temperature district networks without visible infrastructure. By leveraging the extensive Dutch waterfronts, the solution reduces electricity demand and supports the energy transition for developers, municipalities, and port authorities.

Problem
Urban and industrial developments in the Netherlands require extensive damwall construction for water and ground protection, yet these structures remain untapped as energy sources. Without a sustainable, low‑carbon heating and cooling solution, buildings adjacent to waterways rely on electricity‑intensive heat pumps or fossil‑based systems, increasing grid load and CO₂ emissions.
Solution
Energiedamwand Nederland converts the thermal energy of surface water into usable heat and cooling for nearby buildings by integrating collectors into new or existing steel damwalls. A closed-loop circuit circulates a water‑glycol mixture through the wall‑mounted collectors, extracting heat (or cold) from the water and delivering it to a water‑water heat pump with high coefficient of performance. The system operates silently, requires no visible infrastructure after installation, and can feed individual buildings or low‑temperature district heating networks. By leveraging the extensive 10,000 km of Dutch waterfronts, the solution provides a scalable, carbon‑neutral energy source that reduces electricity consumption and supports the national energy transition.
Target Audience
Primary customers are developers, municipalities, and port authorities undertaking waterfront or harbor projects, as well as building owners and operators seeking low‑carbon heating and cooling for residential, commercial, or industrial facilities adjacent to surface water.
Features
- Integrated heat‑exchange collectors mounted on steel damwalls for both new constructions and retrofitted (modular) installations
- Fully closed-loop circulation of water‑glycol fluid, eliminating groundwater extraction and preventing environmental discharge
- Connection to high‑efficiency water‑water heat pumps achieving COP ≥ 5, delivering both heating and cooling
- Scalable pipe network allowing connection of single buildings or large low‑temperature district heating/cooling grids
- Silent, invisible operation with all piping concealed after installation, preserving aesthetic and functional site use
- Proven performance in diverse projects (e.g., Cuxhaven harbor, Delft Green Village, Enkhuizen Compagnieshaven) demonstrating applicability in salt‑ and fresh‑water environments
