Pumped hydro energy storage (PHES), like other hydropower systems, poses several environmental concerns. Here are some of the main environmental issues associated with PHES:
Environmental Concerns
- Alteration of Ecosystems: The construction of dams and reservoirs for PHES can significantly alter natural ecosystems. This includes altering natural river flows, which can disrupt habitats and impact aquatic life.
- Water Sourcing and Rights: Closed-loop PHES, which is not connected to a naturally flowing water body, can face challenges related to water sourcing. This may lead to disputes over water rights and impacts on aquatic resources.
- Flooding Risks: There is a risk of major flooding during the construction phase or in the long term if the dam fails or is not properly maintained.
- Material Usage: The construction phase involves significant use of materials like concrete, steel, and cement, contributing to environmental impacts such as resource depletion and pollution.
- Greenhouse Gas Emissions: While PHES has lower life-cycle greenhouse gas emissions compared to many other energy storage technologies, there are still emissions associated with the construction process and operational inefficiencies.
- Land Use and Displacement: PHES projects often require large land areas, potentially leading to displacement of communities and wildlife habitats.
Despite these challenges, PHES remains a crucial component in the transition to renewable energy due to its efficiency and capacity to stabilize power grids when combined with intermittent renewable sources.
