Hybrid Compressed Air: A totally green energy grid requires large scale energy storage. Pressurized air in salt caverns can store megawatt hours of energy, called Compressed Air Energy Storage (CAES). However, CAES currently lacks the response time needed to compete with gas turbines in the energy market. The objective of our project was to design and simulate the next generation of CAES systems by adding a hybrid element capable of improving the response time to meet grid level energy demands. Ultimately, this can reduce our reliance on fossil fuels.
