The U.S. Department of Energy (DOE) recently released three reports on how to commercialize key clean energy technologies, including pathways for deploying advanced nuclear reactor systems.
The Pathways to Commercial Liftoff: Advanced Nuclear report found that the U.S. will need between 550-770 GW of additional clean, firm power to complement the deployment of variable renewables in order reach net-zero by 2050.
There are only a few options for clean, firm power and nuclear energy is a proven asset that can deliver this at scale.
Based on various models, the report estimates that advanced nuclear could provide about 200 GW of additional capacity by 2050.
The five charts below explain the why and how to make that happen.
Nuclear Power is Key Asset
Advanced nuclear offers a unique value proposition for a decarbonized grid as communities transition away from fossil fuels.
As you can see in the chart below, nuclear energy checks virtually every box.
It generates clean electricity, provides firm power to complement variable renewable energy sources, uses land efficiently, and does not need a lot of transmission buildout.
Advanced reactors can also be used for additional applications, such as clean hydrogen production or water desalination, to help meet the needs of any community.
Advanced Nuclear Provides Economic Benefits and High-Quality Jobs
Nuclear power can also help create higher paying jobs throughout the clean energy transition.
According to the report, small modular reactors are estimated to provide nearly 240 permanent jobs per gigawatt, while traditional large-scale reactors currently employ around 500 per GW.
The chart below also highlights that these jobs tend to have higher industry wages compared to other generation sources.
A 2022 DOE study found that nearly 400 existing and retired coal power plant sites are suitable to host an advanced nuclear power plant. This coal-to-nuclear transition could increase nuclear capacity in the U.S. and provide well-paying jobs and economic benefits to communities that previously hosted coal power plants.
New Nuclear Deployment Is Needed NowThe report finds that waiting until the mid-2030s to deploy advanced reactors at scale could threaten U.S. decarbonization goals and/or lead to significant overbuild of the supply chain.The report explains that if new nuclear deployment starts by 2030 and annual deployment increases to 13 gigawatts (GW) by 2040, the U.S. could deploy an additional 200 GW by 2050.As the chart shows, a five-year delay in scaling the industrial base could lead to a 50% increase in capital required to achieve the same amount of capacity.
