Solutions for Underwater Hydropower Turbine Inspections

Advanced Technology

Innovative Approaches and Materials

Industry

Turbine maintenance often means costly downtime and time-consuming work, particularly when trying to inspect hard-to-reach areas of turbines. GE’s Hydro Solutions’ underwater roboticized turbine inspection vehicle is an option designed to enable quicker turbine inspections without dewatering the equipment. The remotely operated vehicle (ROV) technology requires few personnel to deploy, which can help reduce the time and cost of inspections. It enables facilities to conduct on-demand inspections of turbines to visually evaluate erosion, cavitation, corrosion, or impact marks. It is an example of an innovative technical advancement that provide real-time insights into the health and performance of hydropower facilities, supporting hydropower’s ability to meet changing energy needs.

High-Density Pumped Storage Hydro for Efficient Energy Storage

Advanced Technology

Innovative Approaches and Materials

Industry

Pumped storage hydropower (PSH) currently accounts for roughly 96% of all utility-scale energy storage in the United States, and a new approach developed by RheEnergise could make PSH appropriate for more applications. Instead of using water, the RheEnergise approach uses an inexpensive proprietary fluid that is 2.5 times more dense than water. The higher density fluid can generate the same amount of power as a traditional pumped storage hydropower facility while using significantly smaller tanks and requiring less elevation change. That makes the approach a better fit for landscapes with less elevation and smaller footprints. Designed to provide long-duration energy storage of up to 50 MW at individual projects, the high-density hydro approach can be co-located with other energy projects and leverage existing grid infrastructure. It’s an innovative, cost-effective approach to energy storage that could unlock more opportunities for PSH development to support the grid.
