An engineer from Duke University has proposed a hybrid solar system that uses three renewable energy technologies to convert sunlight into electricity and hydrogen for individual households. The system combines solar, electrolysis, and fuel cell technologies to efficiently capture and store solar energy. While the initial installation costs are higher than fossil fuel generators, hybrid solar systems can compete with fossil fuels and help reduce dependence on natural gas plants. The system represents an environmentally friendly and innovative approach to renewable energy generation that may be worth exploring for implementation in high-rise buildings in Singapore.
