Maintaining and improving water quality has been a longstanding challenge for many hydropower facilities. As new mitigation technologies are developed, we need to improve the monitoring technologies to validate that water quality targets are being met. Pacific Northwest National Laboratories researchers developed a real-time, autonomous and modular water quality monitoring system to enable improved measurement in challenging locations, including dam tailraces. This system reduces risks to workers, provides greater spatial coverage of measurements, and improves communication between the sensor and dam operators. It can help identify and better understand complex issues such as when to implement mitigations, provide more accurate data for water quality models that inform compliance, and enable real-time operational changes to reduce impacts, and potentially increase generation or system flexibility.

A research team from the National Renewable Energy Laboratory will share best practices from their experience instrumenting structures operating in harsh underwater environments, and their experience trying to obtain structural loads data on a deployed marine energy device. Additionally, the webinar will address the following topics:

  • Why data acquisition for marine energy is difficult.
  • Options for strain measurements on operational tidal turbines.
  • Learning from wind: how to model, spec, install, calibrate, and analyze strain gage data on deployed tidal turbines.
  • Lessons learned from the deployment of a data acquisition system on an operation tidal turbine

Until recently, no one had experimented with a range of different techniques for instrumenting subsea components, and it’s difficult to find best practices and guidelines to use. Collecting data in a marine environment requires attention to detail for engineers and technicians. Failure of any one component can lead to failure of the entire system so all parts need to be specified and installed with proper procedures. The research team will share what equipment, techniques, and tools worked for this project, as well as the things that didn’t work and what can be improved in the future.

The number of hydropower facilities facing Federal Energy Regulatory Commission relicensing will double between 2020 and 2030. It’s a process that can draw huge costs both financially and in the time needed. In a webinar on January 26, 2022, Oak Ridge National Laboratory’s Esther Parish, a member of the team behind the Environmental Decision Support Toolkit walked through the online, interactive, and science-based questionnaire, which provides users with a systematic and transparent method for identifying the potential environmental impacts of a proposed hydropower project, cutting down on discussion time.

Tim Welch, Hydropower Program Manager in the Wind and Water Power Technologies Office, introduced Parish and the webinar by asking a broad question: “What does a sustainable hydropower project look like?”  

After multiple studies, the result was the Environmental Decision Support Toolkit designed to:

  1. Characterize and summarize the best-available science for use by diverse hydropower stakeholders seeking to better understand potential hydropower project impacts on the riverine ecosystem.
  2. Provide transparent and consistent methodology for identifying and discussing potential environmental impacts during hydropower licensing negotiations.
  3. Point users toward key river function indicators of concern to reduce the time and cost of hydropower licensing negotiations and promote greater certainty in federal authorization processes for hydropower development and relicensing.

The desired next step is for individuals to use and implement the toolkit.

“We would love to hear the results of how that goes and get feedback on ways we can improve this,” Parish said during the question-and-answer section of the webinar. Learn more by watching the full webinar:

Marine hydrokinetic (MHK) devices for renewable energy power generation are fully or partially immersed in seawater while in service. MHK devices sometimes are made of composites and a variety of alloys. The composite type used is sometimes carbon fiber reinforced polymer (CFRP) composites, other times fiber glass reinforced polymer (GFRP) composites are used. In some cases, the composites are fastened using metallic hardware. The fastened composites can cause tight occluded regions that later could become crevice corrosion on the fastened metal regardless of the type of composite. A modified crevice former was used to investigate crevice corrosion for fastened samples immersed in seawater using CFRP/hybrid composite plates. Three alloys were investigated: 316 stainless steel, Monel and Titanium alloy. Selected samples were removed for visual examination and dis-assembled after more than 270 days (up to 810 days). Crevice corrosion and pitting corrosion was found on the stainless steel and Monel hardware, and corrosion extent increased with time. Download the slides >>
