1 Smart dams

One of the key trends in dam engineering and hydropower is the use of smart technologies to monitor, control, and optimize the performance and safety of dams. Smart dams employ sensors, cameras, drones, and artificial intelligence to collect and analyze data on various aspects of the dam, such as water level, pressure, temperature, vibration, and leakage. This data can help operators to adjust the flow and output of the dam, detect and prevent potential failures, and reduce maintenance costs and risks.

We have found that our Seafloor Systems Solutions have been an integral part of capturing this type of data set. Staked sensory onboard our vessels compound the data collection effectively and efficiently. Where applicable we can design and build custom vessels to serve each specific need. www.Seafloor systems.com [email protected]

2 Floating solar panels

Another innovative technology that is gaining popularity in dam engineering and hydropower is the installation of floating solar panels on the surface of the reservoir. Floating solar panels can generate additional electricity from the sun, while also reducing water evaporation and algae growth. Moreover, floating solar panels can be integrated with the existing hydropower infrastructure, making use of the same transmission lines, inverters, and substations. Some examples of floating solar projects include the 150 MW plant in Anhui, China, and the 40 MW plant in Kerala, India.

3 Fish-friendly turbines

One of the major environmental impacts of dams and hydropower is the disruption of the natural habitat and migration of fish and other aquatic species. To mitigate this problem, some dam engineers and hydropower developers are designing and installing fish-friendly turbines that minimize the harm and mortality of fish passing through the dam. Fish-friendly turbines have features such as low rotational speed, large gaps between blades, smooth surfaces, and pressure regulation. These features reduce the chances of fish being struck, injured, or killed by the turbine, as well as the stress caused by changes in water pressure and flow.

4 Pumped storage

Pumped storage is a technology that allows dams and hydropower plants to store excess electricity and release it when needed. Pumped storage works by pumping water from a lower reservoir to a higher one during periods of low demand and surplus generation, and then releasing it back to the lower reservoir through a turbine during periods of high demand and deficit generation. Pumped storage can help balance the grid, integrate renewable energy sources, and improve the efficiency and reliability of the power system. Some examples of pumped storage projects include the 1,290 MW Dinorwig plant in Wales, and the 1,050 MW Helms plant in California.

5 Green bonds

Green bonds are a type of financing instrument that can help dam engineers and hydropower developers raise funds for sustainable and environmentally friendly projects. Green bonds are issued by governments, corporations, or financial institutions, and are certified by independent agencies or standards to ensure that the proceeds are used for green purposes, such as reducing greenhouse gas emissions, enhancing biodiversity, or improving water quality. Green bonds can attract investors who are interested in supporting green initiatives, as well as offer lower interest rates and tax incentives. Some examples of green bonds for dam engineering and hydropower include the $500 million bond issued by the World Bank for the Tarbela 4 extension project in Pakistan, and the $1.1 billion bond issued by the European Investment Bank for the Grand Ethiopian Renaissance Dam project in Ethiopia.
