The advantages and disadvantages of Pumped Hydroelectric Energy Storage (PHES) and Underground Pumped Hydroelectric Energy Storage (UPHES): A comparative study
The efficiency of Pumped Hydroelectric Energy Storage, a tried and tested energy storage technique, has now reached between 70 and 85 per cent. Globally, PHES installations maintain approximately 3 per cent of generating capacity. However, PHES has traditionally been restricted by geographic parameters; this dissertation considers the value of Underground Pumped Hydroelectric Energy Storage as an alternative to PHES. The study reviews the practical limitations of UPHES, including the progress made to date with this prototype concept. Finally, it offers recommendations for further advancement within the field, including issues of location and funding.
