Using Organic Hydrates (such as 2-(p-isobutylphenyl)propionic acid, known as ibuprofen) as thermal energy storage and moisture-involved electricity generation. Water molecules in organic salt hydrates can be reversibly & thermally cycled i.e. de/re-hydration process. This de/re-hydration process in organic salt hydrates can be used for designing thermal energy storage and also moisture-involved electricity generation systems.
