NuScale Power's SMRs: A Blueprint for Decarbonization and Water Security

The twin crises of climate change and water scarcity are forcing a global reckoning. As droughts intensify and energy demand surges, the search for scalable, carbon-free solutions has never been more urgent. Enter NuScale Power, a company whose small modular reactor (SMR) technology is now redefining the boundaries of what's possible in energy, water, and hydrogen production.

NuScale's recent advancements—particularly its integration of SMRs with clean water desalination and novel hydrogen generation methods—are not merely incremental improvements. They represent a paradigm shift in addressing two of humanity's most pressing challenges: how to power cities without emissions and how to secure access to clean water for billions.

The Water-Energy-Hydrogen Nexus

NuScale's breakthrough lies in its ability to bundle three critical systems into one compact, carbon-free package. A single 77 MWe SMR module paired with reverse osmosis can produce 150 million gallons of clean water daily—enough to sustain 2.3 million people when scaled to 12 modules. Crucially, this process also generates surplus electricity to power 400,000 homes.

But the real innovation is in how NuScale repurposes waste. Brine, a byproduct of desalination, is typically an environmental liability. NuScale's new hydro-thermal chemical decomposition method turns this brine into a feedstock for producing hydrogen—a clean fuel—without relying on energy-intensive electrolysis. This closed-loop system also incorporates direct air capture (DAC) to synthesize sodium formate, a safe hydrogen carrier. The result? A carbon-free hydrogen production process that solves two problems at once: water scarcity and industrial decarbonization.

Partnerships Powering Progress

NuScale's collaborations underscore its seriousness as an industry leader. The U.S. Department of Energy's Pacific Northwest National Laboratory (PNNL) is working with the company to refine the sodium formate process, while partnerships with GSE Solutions and Fuel Cell Energy are advancing solid oxide electrolysis and fuel cell integration. These alliances are critical for scaling up systems that can produce 200 metric tons of hydrogen daily—a benchmark necessary for industrial applications like steelmaking or shipping.

The company's Integrated Energy System simulator in Oregon further highlights its commitment to real-world validation. By testing hydrogen storage, electrolysis, and fuel cells in a controlled environment, NuScale is de-risking what could become a foundational technology for the green economy.

The Investment Case: Risks and Rewards

NuScale's potential is undeniable, but so are the hurdles. SMR technology faces regulatory scrutiny, project delays, and competition from entrenched players like Westinghouse or GE Hitachi. The market's appetite for nuclear innovation also hinges on policymakers: federal subsidies for clean energy and carbon pricing frameworks will determine adoption rates.

Yet the stakes are high enough to justify a closer look at NuScale's stock. As of June 2025, the company's valuation reflects its promise but also its risks. Consider this:

While NUS has underperformed the sector since its IPO, its recent partnerships and technical milestones could catalyze a revaluation. The global market for clean hydrogen alone is projected to reach $150 billion by 2030, with water desalination needing $100 billion in annual investment to meet demand. NuScale's integrated solution sits at the intersection of both.

A Long-Term Play in the Energy Transition

NuScale isn't just a nuclear company anymore. It's a platform for sustainability, offering utilities and industries a path to decarbonize while solving water shortages. Its SMRs could become the backbone of “hydrogen hubs” and water-reuse networks in regions from California to the Middle East.

For investors, the question is whether to bet on NuScale's execution over the next decade. The risks are real—technological, regulatory, and financial—but so is the opportunity. In a world where water and energy security are existential imperatives, NuScale's vision could crystallize into a multi-billion-dollar franchise.

In the end, the most compelling argument for NuScale isn't its technology alone. It's the company's ability to package three critical systems into one scalable, carbon-free solution. For investors willing to look beyond the near-term noise, that's a blueprint worth watching.
