A powerhouse group of graduating seniors from the University of Colorado Boulder made waves in a sustainable challenge that’s all about energizing the future.

�ճ����CU Hydropower Team took part in this year’s��, where 12 teams from universities across the country were tasked with developing unique energy solutions using fresh, moving water—one of the Earth’s oldest forms of renewable energy.

But they weren’t just participants. They were overwhelming winners, earning first-place honors in a variety of contests within the competition, including the highly coveted Overall Best Team award.

“We had a great group and a really good workload sharing system,” said Logistics Manager Miles Salzer. “We weren’t really sure how we were going to do or what the outcome would be. There were a lot of challenges, but we overcame them and we’re proud of what we were able to accomplish.”

The competition, sponsored by the Department of Energy and the Water Power Technologies Office, was launched in 2022. It allows teams to showcase their engineering prowess by conceptually designing plans for either an electricity generating power dam or a functioning closed-loop pump storage facility.

The team chose to tackle the closed-loop pump storage facility—a novel hydropower solution that features two independent reservoirs that transport water back and forth, much like the sand in an hourglass. The system is also hydrodynamically sealed, preventing water from exiting the system.

CAD Engineer Jack Printup says this new pump storage concept is currently growing in popularity as a clean energy and sustainable alternative, but there are still some environmental risks involved.

“It’s basically a big water battery that lasts longer and is more consistent than other nonrenewable sources, but like nuclear plants, they can cause some damage to the area around it,” Printup said. “Our task was to choose and develop a site for our pump storage facility that was safe and could be implemented in the real world.”

But the competition doesn’t just focus on technical design. Judges also assessed the team’s ability to manage their facility’s finances and cybersecurity.��

They even measured the group’s ability to use digital tools to increase community awareness or quickly pitch their plan to a panel of “investors” in an environment reminiscent of the hit TV show “Shark Tank.”

Luckily, Salzer said the group was perfectly equipped to handle the interdisciplinary obstacles with a well-rounded force of their own. The team featured students from the��Paul M. Rady Department of Mechanical Engineering, the��Environmental Engineering Program, the��Department of Computer Science and even the Leeds School of Business.

“I think the different backgrounds made our group really unique,” said Salzer. “Hydropower—and renewable energy in general—are large and complex infrastructure projects. One of our team’s biggest strengths compared to other teams was our varied skill sets that allowed us to handle all of the challenges.”

Most importantly, however, the competition is designed to help college graduates develop skills, connections and interest in the hydropower industry.��

Printup says increased activity and engagement in hydropower can be crucial, and this competition really sparked his passion.

“There are spurts in the hydropower industry—you build a large plant and then 60 years later it needs to be refurbished or new facilities need to be built,” Printup said. “I’m going into hydropower to continue developing this incredible technology, but also make sure public safety is at the forefront.”
