Recent advancements in technology are indeed aimed at reducing the startup costs of pumped hydro storage (PSH). Here are some key developments:
Recent Advancements Reducing Startup Costs
- Underground Construction Using Tunnel Boring Machines (TBMs):
- This method involves using TBMs to excavate channels between natural aquifers, mimicking the function of upper and lower reservoirs in a closed-loop PSH facility. TBMs require less construction, equipment, and time, potentially reducing costs by decreasing excavation time by 50%.
- Modular Steel Dams:
- Construction of PSH facilities using modular steel dams can reduce both construction time and costs. The dams are built off-site and assembled on-site, which could cut construction schedules in half and reduce costs by one-third.
- Modular, Closed-Loop, Scalable PSH Systems:
- This approach involves standardizing components like penstocks and water bladders to replace traditional reservoirs. It aims to reduce the time and cost of building PSH facilities by simplifying their design and deployment.
- Innovative Excavation and Construction Methods:
- Advances in excavation methods include the use of roadheader machines and oscillating disc machines. New dam construction techniques, such as modular dam construction using precast concrete blocks or steel, can also reduce costs and construction time.
These innovations have the potential to make PSH more cost-competitive by streamlining the construction process and reducing the initial investment required.
