Case Studies

In April 2022, the U.S. Department of Energy (DOE) awarded a $2.5 million grant to Constellation and its project partners to explore the benefits of constructing direct air capture (DAC) technology at the company’s Byron nuclear energy plant. While nuclear plants do not produce any carbon emissions, direct air capture would remove carbon dioxide directly from the atmosphere, a possible next-generation technology to help our nation combat the climate crisis.

The DAC project at Byron Generating Station could capture 250,000 tons of CO2 each year, reducing global carbon emissions and helping to decarbonize energy intensive sectors of the economy. The study will also focus on the potential for a nuclear plant to become the center of a direct air carbon capture hub, partnering the DAC technology with storage of CO2.

Achieving 100% carbon-free power is a key sustainability goal for many organizations. As customers make the transition to 100% carbon-free, many are looking to bridge the gap between their real-time electricity demand and available sources of carbon-free power. Currently, energy markets have limited options for tracking and matching carbon-free supply with demand on an hour-by-hour basis, and most organizations pursuing zero emissions power match their electricity use with renewable energy certificates, or RECs, on an annual basis.

Constellation was the recipient of a Department of Energy (DOE) grant in 2021 to explore the potential benefits of on-site hydrogen production at Nine Mile Point Nuclear Station in Oswego, NY. Constellation will partner with Nel Hydrogen, Argonne National Laboratory, Idaho National Laboratory, and the National Renewable Energy Laboratory to demonstrate integrated production, storage, and normal usage at the station. The project will generate an economical supply of hydrogen, a natural byproduct of nuclear energy, to be safely captured, stored, and potentially taken to market as a 100 percent carbon-free source of power.

Learn more about this project and, more broadly, how clean hydrogen, produced by emissions-free power, holds the key to solving the climate crisis.

NET Power, LLC is a strategic venture between Constellation, 8 Rivers, McDermott, and Occidental Petroleum. The mission of NET Power is to provide advanced clean energy to consumers worldwide by generating lower-cost power with zero emissions. NET Power is a clean energy technology company that promotes, develops, and licenses a proprietary process for efficiently generating electricity from natural gas while capturing all CO emissions. NET Power’s revolutionary technology promises to enable the world to meet its climate goals without paying more for electricity.

Constellation engages in energy storage technology development through a strategic relationship with Volta Energy Technologies. Through this relationship, Constellation has invested in four storage companies with transformational solutions relevant to the grid. Constellation and Albemarle Corporation, the leading lithium supplier for energy storage and other applications, were the founding investors in Volta in 2017.

Constellation collaborated with Kevala, Inc., a nationwide leader in energy data and grid analytics, and leading energy and utility providers National Grid and ComEd, an Exelon company, on groundbreaking new carbon accounting research in 2021. The companies released a joint whitepaper, "Total Carbon Accounting: A Framework to Deliver Localized Carbon Intensity Data," which explores advanced analytic methods designed to better compute the carbon intensity of grid electricity with higher degrees of geographic and temporal granularity. These methods can help ensure the energy sector is best equipped to evaluate, prioritize, and measure decarbonization activities in the future. In leveraging TCA's comprehensive methodology, key energy stakeholders can more accurately match carbon-free power supplies to load forecasts.

Rolls-Royce Holdings plc and Constellation signed a Memorandum of Understanding in 2020 to pursue the potential for Constellation to operate compact nuclear power stations both in the United Kingdom and internationally. Constellation will be using its operational experience to assist Rolls-Royce in the development and deployment of the UKSMR.

Constellation Responds to Advanced Clean Electricity Initiative RFI

Already the largest producer of reliable, always-on, zero-carbon energy in the nation, Constellation knows how important clean, firm energy is. We are helping to bring more of it to the system by seeking license extensions for our existing nuclear fleet and adding equipment that can increase its output, both of which provide additional clean power. 

On April 12, we responded to the RFI from Microsoft, Google and Nucor on ways to bring more advanced clean, firm energy technologies online to meet growing demand. Our response to their RFI outlined our unique capabilities and characteristics that can help developers of new clean, firm generation to overcome barriers. 

One of the significant hurdles for new clean energy deployment is siting. Constellation can help solve siting challenges by locating new small modular reactors or other advanced reactors at our existing nuclear plant sites, which already have local community support, security, rail and road access, access to water and barge infrastructure, available land, and have operating assets already federally licensed by the Nuclear Regulatory Commission.
