How long do pumped hydropower batteries last?
In literature, the life span of pumped hydropower storage ranges from 50 to 150 years with almost no performance deterioration [43, 44]. A period of 80 years was chosen for the base case. There is no long-term evidence yet for life spans of utility-scale batteries, as this is a recent and continuously evolving technology.
How long does pumped hydropower last?
The ecoinvent database for example assumes a life span of 150 years as a default for pumped hydropower, where this occurs within the ecoinvent data for the German electricity mix. This life span has been confirmed as realistic by an operator of pumped hydropower storage.
How long does a pumped hydro store last?
The first sensitivity analysis uses a life span of 150 years for the pumped hydro store, in line with the ecoinvent assumption. The assessment period, however, remains at 80 years. This approach leads to the impacts of the production and end-of-life stage being distributed over a greater number of years.
