Advancing Marine Energy Technologies Through State-of-the-Art Facilities
By Caitlin McDermott-Murphy
This article kicks off the “Found at Flatirons” series highlighting distinctive technologies developed at NREL’s campus located in Arvada, Colorado.
Within an expansive testing area characterized by robust concrete walls and fitted with advanced machinery, a crane delicately maneuvers a small replica of a lunar lander out of a large water tank. Water droplets cascade off the metallic structure as it is lowered onto solid ground. With the machine now primed for action, the countdown begins.
Brittany Lydon, a graduate student studying mechanical engineering at the University of Washington noted that this moment felt akin to an intense pit stop during a race car event where every second counts. While her apparatus won’t be venturing to space anytime soon; it’s being prepared to tackle another demanding environment—the ocean.
Harnessing Ocean Power
Lydon’s innovative device aims to capture wave energy—a resource classified within marine energy sectors known for being challenging yet promising as it harnesses kinetic potential from currents and tides present in our oceans and rivers. Ample statistics indicate that U.S waters have sufficient marine energy potential capable of fulfilling approximately sixty percent of national electricity requirements—though extracting even a fraction could significantly benefit offshore industries (such as aquaculture), empower coastal communities during outages or natural disasters and assist in achieving broader national energy objectives.
Nonetheless, developers encountering hurdles while pioneering new marine energies require specialized facilities outfitted with tools designed explicitly for evaluating cutting-edge technology like theirs. For example; researchers working on solar panels can simply test prototypes outdoors but deploying untested equipment into unpredictable ocean environments resembles sending an experimental spacecraft into orbit without proper preparation.
Navigating Unpredictable Waters
“In certain respects; one might argue space exploration poses less complexity compared to tackling ocean challenges,” stated Ben McGilton.” An electrical engineer attached to NREL who focuses on advancing systems in marine energy technology further elaborated that aspects such as gravity radiation/vacuum may adhere predictably whereas volatile conditions encountered beneath salty seawater encompass unforeseen variables difficult if not impossible perfectly replicate beforehand,’ he said.<''em>

Innovations in Ocean Energy Testing: NREL’s Revolutionary Approach
The Challenge of Ocean Deployment
While engaging with ocean energies presents exciting potential, the unpredictable nature of marine environments poses significant challenges. As Ben McGilton articulates, “There’s a common belief in marine energy that the rare but monumental wave event can occur right after deployment.” Such unpredictability necessitates thoughtful preparations and thorough testing before venturing into open waters.
Bridging Laboratory Insights to Ocean Applications
To mitigate these risks, the National Renewable Energy Laboratory (NREL) has developed innovative testing facilities that serve as crucial bridges between theoretical models and real-world applications. In 2021, NREL introduced its inaugural wave tank at the Scenic Wave Energy Lab (SWEL). This facility is engineered to recreate scaled ocean waves indicative of various global sites. Fast forward to 2023, an addition called the Large-Amplitude Motion Platform (LAMP) was launched. This machine simulates immense ocean movements without requiring actual water.
Advanced Testing Facilities for Thorough Analysis
In addition to wave simulation facilities like LAMP and SWEL’s tank, NREL is equipped with advanced dynamometers capable of rigorous evaluations on electrical components of devices. They also possess rapid manufacturing tools such as 3D printers for quick part production in case repairs are necessary. The laboratory’s virtual systems allow researchers to connect real hardware while modeling different device elements along with diverse oceanic conditions and electrical infrastructures.
As a result, developers can analyze how their technology performs under conditions akin to those experienced during harsh winters off Hawaii’s shores—assessing structural integrity or potential energy output for local grids—without incurring high costs or facing environmental hazards associated with direct maritime trials.
Validating Performance Before Marine Trials
“It’s crucial that we have laboratory resources available for validation before engaging with open waters,” emphasizes McGilton. He elaborates on testing challenges: striking out on field tests incurs exorbitant expenses alongside myriad risks tied to uncertainty regarding varied aquatic conditions.
His colleague Jenne aligns himself with this perspective given his first-hand experiences navigating both approaches.
Unveiling HERO: A Water-Saving Innovation
In 2020, Jenne led an initiative focusing on developing a Hydraulic and Electric Reverse Osmosis (HERO) Wave Energy Converter (WEC), aptly named HERO due to its life-altering potential for communities impacted by natural disasters where access to fresh water is compromised post-event. Designed specifically to generate potable water using seawater through wave power technology—the HERO WEC represents a substantial advancement in renewable resource use.
Deployments Facing Unexpected Obstacles
The prototype made its debut near North Carolina’s Outer Banks in 2022; however, Mother Nature had other plans—only delivering two favorable weeks within a fortnight period as stated by Jenne: “The conditions were primarily stagnant during our deployment.”
Despite this challenge, recourse was available through LAMP—a simulator providing nearly any conceivable wave condition without exposure concerns from storms or placid waters—as found during their field trial.

Through leveraging advanced technologies such as those at NREL—including state-of-the-art simulations—they continue iterating designs efficiently prior deploying into unpredictable marine arenas ultimately streamlining innovation cycles toward desired outcomes beneficial not only locally but globally too!
Advancements in Ocean Energy Testing: A New Wave of Innovation
Transforming Marine Energy Research
In the ever-evolving field of renewable energy, ocean energy presents a unique opportunity for harnessing power from our planet’s waters. The National Renewable Energy Laboratory (NREL) has stepped up its game by employing innovative test facilities like LAMP (Large Appliances and Marine Platforms) to accelerate breakthroughs in ocean technology prototypes.
Controlled Environment for Optimal Discovery
According to NREL’s Jenne, conducting tests in controlled environments is vital. “Deployments at sea provide invaluable insights which cannot be replicated on the LAMP setup,” he explained. Nevertheless, having a facility where wave conditions can be simulated on command allows researchers to gather critical data efficiently.
During recent testing with the HERO WEC (Wave Energy Converter), challenges arose as its drivetrain experienced severe lock-up issues, leading to damage of the mooring line. Yet, thanks to NREL’s controlled setting, troubleshooting was performed swiftly—allowing testing to resume only days later. In contrast, an Outer Banks deployment faced setbacks due to unexpected weather conditions that left equipment stranded for weeks before any solutions could be implemented.
“Investments made at sea often yield limited findings due to unpredictable factors,” Jenne stated. “With LAMP, we managed over 100 distinct scenarios within just one month.”
Innovative Solutions from SWEL Tank Testing
Seeking further data diversification led Dr. Brian Polagye and his team from the University of Washington toward another valuable resource—the SWEL wave tank operated by NREL. Unlike traditional WEC designs such as HERO, their prototype emulates movement similar to sea grass swaying amidst waves.
While their own facility was functional but too small for comprehensive tests—risking skewed results due to proximity constraints—SWEL offered ample space designed for prototypes approximately 1/75th scale relative to full-sized energy devices.
Through transparent walls allowing real-time observations below and above water levels that mimic natural conditions more closely than murky oceans do, researchers can utilize advanced motion-tracking systems paired with sensors for detailed insights into device performance.
Supported by TEAMER—a program financed by the U.S. Department of Energy’s Water Power Technologies Office—the research team tested extensively over months during early 2024 and gathered substantial datasets rapidly.
As Lydon remarked about her experience there: “It was surprisingly uneventful—which signifies success in this field.” Maintaining a consistent operational status while gathering data efficiently is what engineers aspire towards; it substantiates reliability amid dynamic testing scenarios.
Comprehensive Support Ecosystem at NREL
In recent years, NREL has transformed its capabilities into an all-encompassing service model that Rebecca Fao describes as offering everything necessary “from beginning concept design through final prototype production.” This progression supports modeling tasks via award-winning tools while ecosystem synergy fosters development stages up until real-world hardware implementation against realistic grid simulations or marine settings mimicking true environmental variables effectively.
Ben McGilton emphasizes their capacity: “We assess entire systems’ interactions with microgrids or community-scale infrastructure—not merely through simulation but actual electrical standards.”
Attraction lies not solely within sophisticated facilities; personnel also play a key role in troubleshooting failures whilst assisting active participation during experiments across various engineering domains within NREL’s expert assembly—a vital element driving successful developments forward according to previous studies indicating higher success correlations rooted deeply among collaborative environments conducive towards innovation attainment goals down-track milestones lined ahead successfully achieved promptly thereafter boosting ambitious aspirations driving marine initiatives continuously resonating amongst emerging technologies still young today!
