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.
The use of fictive storage can help to better document lost flexibility in the hydropower system when changing or introducing new environmental measures.
Researchers from HydroCen have taken over 400 DNA samples from Norwegian rivers. The aim is to analyze as many as 800 samples nationally to investigate how various forms of hydropower affect species living in the river. Ultimately, the goal is to help the hydropower industry produce more sustainable renewable energy.
The Balkan region gets most of its electricity from coal-fired power plants but is now looking for solutions that can give them a greener energy system.
Researchers are about to uncover the secret life of kelts in the river. These winter-survivors are important for securing the salmon population, and now researchers seek to help them pass obstacles in the river come spring.
Researchers seek to use turbulent eddies in the river to safely guide salmon and eels past hydropower plants.
