In the Sustainable Flexibility Metrics (SusFlexMet) project, HydroCen researchers have developed a framework for assessing how power production in hydropower plants can be as flexible as possible with the least amount of impact on the environment and costs.
New method uses DNA to determine the number of salmon spawning in the river. It is important for the hydropower industry and management authorities to know how viable the population is when conducting revisions of terms of hydropower licenses or environmental measures, and this method is both quick and cost-effective.
New research shows that risk of dam breach can be drastically reduced in overtopping situations. By improving the placement of the rocks protecting the downstream slope of rockfill dams against erosion and securing the "dam toe" at the foundation, the risk of damages can be reduced - and in extreme cases, it can prevent or delay collapse.
For the first time all the Research Centers for Environmentally Friendly Energy (FME) are coming together to discuss how we can be enablers in mitigating climate and energy challenges. Join us at NTNU's Energy Transition Week 2024!
Shooting sound waves through water can eliminate gas bubbles that harm wildlife in rivers with power production. Researchers have explored various methods in the laboratory, and now they’re ready to test the best one on a large scale in actual power plants.
Environmentally friendly hydropower was the topic at the international conference "Sustainability in Hydropower". The presentations are now available online.
Norwegian hydropower plants are currently undergoing a digital transformation in which access to, and utilization of, data are crucial. Within the HydroCen project, researchers have established a laboratory for developing digital twins.
Researchers from Europe and USA are working together to find solutions to challenges that arise in energy systems as we transition towards a zero-emission energy system, with a particular focus on the roles and opportunities of hydropower. The work from the project HydroFai was recently summed up in a workshop where experts from Argonne and Pacific North-West national laboratories and HydroCen, along with industry experts, presented information about developments in electricity market designs in Europe and the United States.

Frequent temperature changes due to flexible hydropower production can weaken the insulation in the stator coils in the generator. Analyzes from HydroCen can help power producers plan more favorable production patterns that result in less wear and tear.

New knowledge about how sand and debris in the water wear down the turbine, can forward the development of turbines that are better equipped to operate in areas with a lot of sediments in the water. HydroCen researcher Nirmal Acharya has worked on a simplified model which extends the general erosion model predicted by previous studies.
