STATUS In Progress
Climate change is increasing the risk of flooding, both in coastal and delta regions. The Netherlands is a country that lives underwater. For the Dutch, water is a friend and foe, the country’s location boarding the North Sea and being the delta of Europe’s major rivers has brought a lot of prosperity, but it has also made the Netherlands vulnerable to flooding. This means that more than 1100 kilometres of dijk and 256 locks and pumping stations will need to be reinforced and improved by 2028.
Delta 21 is a unique concept; the project would use the best Dutch water builder traditions with the aim to turn harness nature’s natural energy by using large-scale sustainable and energy conserving approaches. C Concept Design was engaged to develop the concept and visualizations for this ambitious collaborative project. The project includes the development of an artificial island and lake that will serve as flood protection, allow energy generation and storage, guarantee of fresh water for Rotterdam and the surrounding area and allow the salt tide fish migration between the North Sea and Rhine/Maas.
At the heart of Delta 21 is the Valmeer, a 20 km2 water storage basin, will produce its own electricity from the surplus water of the on-site turbines. To drain the Valmeer in 12 hours, requires 93 pumps of 20 MW, this generate electricity as the turbines are energized when the water basin is filled again. This has the potential to result in an energy transition for Rotterdam as the storage capacity for electric power in the Energy Storage Lake will make it possible to close two large (coal) plants by 2030. In total this will equate to 6 Twh of ‘clean’ energy that can be generated annually with the water turbines. IT has estimated that, by 2030, the project will yield 110 million euros per year in energy production. Furthermore, it will be saving up to four megatons of CO2 emissions per year, and with the price level of a CO2 tonne being 50 euro, this also generates a saving of 200 million euros annually. This is in addition to the savings from not having to raise and reinforce the Dijks– at a value of 2 billion euros through 2050 and over 6 billion euros by 2100.
This project will start a new trend in the water management and change how we all look at conservation, energy production and storage and coastal protection methods over the next 10 years. Check out more information about the plan, here.
THIS PROJECT IS A COLLABORATION BETWEEN: TU DELFT, UNIVERSITY OF WAGENINGEN, DEME AND VAN OORD.
