How Mountains Could Store Mountains of Clean Energy

As the country transitions to a carbon-free power grid, researchers are searching for the best ways to store energy for use when winds die down, clouds block the sun, and the grid needs a boost. Some experts are hoping to forge better batteries, like the well-loved lithium-ion batteries that power electric cars. But batteries are like cheetahs—they’re best for short distances. DOE states pumped storage hydropower may be older, but, like the high-endurance ostrich, it can outlast its cousins, storing energy for up to 12 hours at a time (whereas a battery can store about 4 hours’ worth). To further facilitate this form of storage, NREL researchers created a new cost estimation tool that can evaluate the potential construction and labor costs associated with closed-loop pumped storage hydropower plants. Read more about how the new tool can support the evolving U.S. power grid.

Hydropower Investment Landscape Study

A new report, Hydropower Investment and Public-Private Ecosystem Assessment, developed by the National Renewable Energy Laboratory and funded by WPTO, provides a comprehensive analysis of both the risks and opportunities for investing in small- to medium-sized hydropower and pumped storage hydropower projects. Read the full article Hydropower Investment Opportunities on the DOE website, to learn more about the key findings and opportunities to increase investment in hydropower. You can also dive deeper into the new hydropower investment landscape report.

Do We Still Need Hydropower?

Switching to 100% clean energy means keeping carbon out of our atmosphere. And we’re getting there. Solar panels and wind turbines are more affordable and efficient than ever before. But they’re not foolproof. A clean energy grid needs a clean energy partner that can balance grid fluctuations when the sun sets and winds slow. Many hydropower facilities can start and stop within minutes or even seconds. And, like thermal power plants—coal and the like—hydropower can provide something called grid inertia: If a system failure disrupts the power grid, the plant’s large machinery keeps moving, like a stalled car on a hill, so communities can continue to get some power while workers fix the glitch. Read more about why hydropower is essential in the battle against climate change.

WaterPACT Project to Quantify and Reduce Plastic Waste in U.S. Rivers

Rivers are nature’s highways, supplying nearby areas with life-sustaining water, nutrients, and biodiversity on their journeys to larger bodies of water. These days, however, they are far from pristine. A harmful substance is making its way down rivers and into oceans around the world: plastic debris. The WaterPACT project is on a mission to develop renewable-energy-powered technologies to detect, quantify, and collect plastic from U.S. waterways. With collaboration from researchers at the Pacific Northwest National Laboratory, the NREL-led Bio-Optimized Technologies to keep Thermoplastics out of Landfills and the Environment consortium, and the Environmental Molecular Sciences Laboratory, the WaterPACT project aims to reduce the volume of plastic currently entering the ocean annually via U.S. waterways by more than half by 2040. Read more about how WaterPACT is addressing plastic pollution.

Can Ocean Energy Power Carbon Removal?

Researchers at NREL authored a new study to examine various methods to capture carbon dioxide from the air or ocean and permanently sequester or store it—or, better yet, do both simultaneously. For their study, which was funded by WPTO, researchers analyzed the benefits and drawbacks of each of the most promising marine carbon management techniques. But they also looked at how the country—and the world—could power these carbon-snatchers, especially those that operate in the remote ocean, far from any power grid. Learn why offshore energy could help the world reach critical carbon removal goals.

Offshore Wind Makes Fiscal Sense For Alaska

Offshore wind makes the most sense to decarbonize energy production in Alaska when compared to electricity from waves or tides, according to an analysis by NREL researchers. Their new U.S. Department of the Interior report, Feasibility Study for Renewable Energy Technologies in Alaska Offshore Waters, was conducted for the Bureau of Ocean Energy Management to evaluate which renewable energy options could be optimal for Alaska. The study area included state waters outside of the Bureau of Ocean Energy Management’s jurisdiction to allow broader consideration of tidal and wave energy, which are often more powerful closer to shore.

How NREL Experts Are Working To Accelerate Deployment of Domestic Coastal Structure Integrated Wave Energy Converters

In a new webpage, NREL researchers explain the potential benefits of a specific kind of wave energy technology called coastal structure integrated wave energy converters. These dual-purpose technologies, which are installed in breakwaters, could provide coastal communities with both clean energy and protection from erosion and coastal storms. Now, a team of NREL experts are working to accelerate the deployment of coastal structure integrated wave energy converters in the United States, so these technologies can help support local jobs and power desalination, ocean observation, aquaculture, and even the grid.

Beneath the Surface: Alec Schnabel Has the Power (and the Power Electronics) To Advance Wave Energy

Alec Schnabel

Most kids who grew up in chilly, snow-prone areas remember the dreaded five-day rule: After five snow days savoring hot chocolate and chucking snowballs, any extra had to be traded for precious summer vacation days.

Alec Schnabel was one of those kids. Growing up in central Ohio in the 2000s, he remembers eclipsing the five-day rule more winters than not. But then, as he got older, something changed.

“We saw less snow,” Schnabel said. “And now it’s very green during the winter, always. In Ohio, we get some snow, but it just melts instantly.”

Schnabel, who is now a marine energy researcher at NREL, is part of the first generation to see climate change alter their world in real time—an experience that can be just as powerful and terrifying as watching a loved one age.

Less snow might seem like an insignificant or even welcome change—except to the kids who miss out on a snow day’s crystalline joy. But the internet broadcasts a never-ending reel of climate change’s more sinister havoc, like devastating wildfires, more violent tropical storms, and crop-decimating droughts. (By the way, Ohio’s snow loss is not insignificant; according to a Weather.gov article, less snow could be connected to summertime drought and a spike in tick populations according to this article by The Ohio State University).

“Something about climate change bothered me, really sat with me,” Schnabel said. “I really wanted to be a part of finding some sort of solution.”

Now, he is.

In this Beneath the Surface profile, Alec Schnabel shares why he decided early on in his career that he wanted to help find solutions to combat the crisis.
