Eco-friendly Concrete Substructures for Durable Offshore Floating Solar Power Plants

energyTestedTRL 5

Imagine putting solar panels on the ocean, but the salt and waves usually destroy the supports. This project creates a special kind of 'green' super-concrete and bio-based paint to keep those supports from rusting or rotting. It's like giving a floating power plant a protective, eco-friendly armor that lasts much longer in harsh seas.
