Detailed overview of innovation with sample startups and prominent university research


What it is

Environmental mitigation technologies for hydropower aim to minimize the negative impacts of hydropower projects on surrounding ecosystems and aquatic life. These technologies address various environmental concerns, including fish passage, sediment management, water quality, and habitat restoration.

Impact on climate action

Environmental Mitigation Technologies within Hydropower advance climate action by minimizing the ecological impacts of hydroelectric projects. By preserving biodiversity, restoring habitats, and mitigating fish passage barriers, these innovations ensure sustainable hydropower development, reducing carbon emissions and promoting renewable energy sources in harmony with the environment.

Underlying
Technology

  • Fish Passage Solutions: These technologies facilitate the safe passage of fish around dams and through turbines, mitigating the impact on fish migration and populations. Examples include fish ladders, fish lifts, fish bypass channels, and fish-friendly turbine designs.
  • Sediment Management: Sediment management technologies address the accumulation of sediment behind dams, which can negatively impact downstream ecosystems and reservoir health. Examples include sediment bypass systems, flushing flows, and dredging.
  • Water Quality Management: Technologies are used to monitor and improve water quality in rivers and reservoirs affected by hydropower projects. This includes monitoring dissolved oxygen levels, temperature, and other water quality parameters, as well as implementing measures to mitigate negative impacts.
  • Habitat Restoration: Habitat restoration projects aim to restore or enhance aquatic and riparian habitats that have been impacted by hydropower development. This can involve restoring natural river flows, creating new habitats, and planting native vegetation.
