Integrated Hydrogen Sensor/Separation Module Boosts Long-Term Efficiency and Revenue in Solar Power Plants

Concentrating solar power (CSP) plants generate clean energy to power our communities. Yet, one consistent challenge of CSP plants is hydrogen buildup, which can be costly to mitigate and reduces plant efficiency. NREL researcher Greg Glatzmaier has spent much of his career finding a solution.

Renewables Rescue Stability as the Grid Loses Spin

Across the world, renewable power is displacing traditional generation, but can renewables also replace the critical stability functions that go with it? NREL studies are confirming in the field and on live power systems that solar, wind, and hybrid power plants can provide their own source of grid stability—potentially unlike anything currently on the grid.

From Lab to Tundra: Building a More Efficient Future with Rural Alaska

In a small Athabascan village on the Yukon River, a new house is going up. Tribal leaders in Huslia, Alaska, hope homes like this will attract health care and law enforcement workers to the remote Arctic community. Staying warm is the center of life at this latitude and the driving purpose of the Cold Climate Housing Research Center.

Grid Coordination Opens Road for Electric Vehicle Flexibility

As electric vehicle sales continue to rev up in the United States, the power grid is in parallel contending with the greatest transformation in its 100-year history: the large-scale integration of renewable energy and power electronic devices. The changes will test the limits of grid integration, but NREL sees opportunity at the intersection of energy systems and transportation.

From Space Travel to Fisheries: Wave Energy Modeling Tool Helps Design Tomorrow's Tech

NASA is using WEC-Sim (Wave Energy Converter SIMulator), an open-source code developed by NREL and Sandia National Laboratories, to ensure NASA’s Orion Crew Model uprights and remains upright upon landing in the ocean.

Blockchain: Not Just for Bitcoin

A common vision for the future of the nation's energy grid involves homeowners selling unused power generated from rooftop solar panels to others in their communities, and working together to help ensure the reliability, resiliency, and security of the power grid everyone uses. But how can the grid manage such complex energy transactions at scale? Several emerging solutions rely on blockchain technology.

NREL Research into Fueling Big Rigs Could Help More Hydrogen Vehicles Hit the Road

Hydrogen-fueled cars are increasingly popular in California, but moving beyond the state's borders may require 18-wheelers crisscrossing America's highways leading the way. Research at NREL suggests a shift in long-haul trucking toward hydrogen that could drive a coast-to-coast network of fueling stations.

50th Anniversary of Earth Day Puts NREL Research in Focus

Five decades ago, an idea sprouted into an event that grew into a movement, which today, on its 50th anniversary, we recognize as Earth Day—a global day of awareness and a celebration of principle, responsibility, and sustainability. NREL has always enjoyed strong ties to Earth Day. The laboratory's second director, Denis Hayes, played a key role in its creation, coordinating the first Earth Day in 1970.

Buildings Research Sets Foundation for Future Design

"Earth Day is about looking at how we use energy and how we can increase sustainability by reducing our negative impact on Earth," said NREL's Roderick Jackson. "Buildings are the largest consumers of energy. If a building can be designed in a way that allows us to accelerate that clean energy future… that's what we're doing here."

Bifacial Solar Advances with the Times—and the Sun

Traditional solar modules convert light to electricity using photovoltaic cells on the top side of the panels. Now, NREL researchers are shining a light on what lies beneath. Data from June through November 2019 revealed up to a 9% gain in energy production using bifacial panels compared with their one-sided cousins.

Declining Renewable Costs Drive Focus on Energy Storage

An oft-repeated refrain—the sun doesn't always shine, is sometimes seen as an impediment to renewable energy. But it's also an impetus toward discovering the best ways to store that energy until it's needed.
