Air storage vessels vary in the thermodynamic conditions of the storage and on the technology used: 1. Constant volume storage ( caverns, above-ground vessels, aquifers, automotive applications, etc.)2. Constant pressure storage (underwater pressure vessels, hybrid pumped hydro / compressed air storage)
[pdf] The project, built by the Chinese state-run energy giant PowerChina and financed by Zambia’s national utility ZESCO, is designed to stabilize power for mining operations, the lifeblood of Zambia’s economy.
