Delta21 offers an innovative solution that combines flood protection, large-scale energy storage, and nature conservation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the mouth of the Haringvliet, a unique system is to be created featuring a large drop lake that functions as a natural hydroelectric battery. This will allow renewable energy to be stored and released during periods of high demand. At the same time, the system will help protect against flooding and provide opportunities for ecological restoration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A Unique Collaboration Among 24 Partners<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Delta21 is not only technically innovative, but also unique due to the collaboration between 24 companies, energy cooperatives, and civic organizations.
