To hit its 2050 decarbonization targets, the U.S. is focused on tripling its nuclear power, adding over 200 GW of new capacity. Net-zero models highlight the need for this expansion, but how will the U.S. make it happen? The key strategies include deploying advanced reactors, streamlining regulations, boosting public-private partnerships, and investing in critical infrastructure. These steps will pave the way for a cleaner, more sustainable energy future.
The U.S. currently operates 94 nuclear reactors across 54 sites, providing about 20% of the nation’s electricity and nearly half of its carbon-free energy. These reactors are Light Water Reactors (LWRs), with 63 pressurized water reactors and 31 boiling water reactors. The average capacity of these reactors is 1031 MW, with the smallest at 519 MW and the largest at 1401 MW.
Unlocking the U.S. Nuclear Energy Future with Gen III+ and IV Reactors
The DOE has explained the need for both Gen III+ and Generation IV reactors to meet the 3X capacity by 2050. For example, LWRs, bolstered by the recently launched Gen III+ reactors at Vogtle are highly efficient in meeting the immediate energy demands.
Generation IV reactors, on the other hand, offer the advantage of producing higher temperatures, which are ideal for industrial uses. Although some of these designs date back to the 1950s, they have limited operational experience. This means they will need significant investment to reach commercial viability.

Cost Efficiency, Selection, and Standardization of Nuclear Reactors
Making nuclear energy more affordable hinges on selecting and standardizing reactor designs. Different markets, however, need other solutions that are ideal for large-scale electricity generation, such as powering data centers. In contrast, industries needing high heat or steam may benefit from next-gen technologies like Gen IV reactors. Remote areas may require more specialized designs.
Multi-unit plants help cut costs, with a 30% per megawatt-hour saving compared to single-unit plants. While 19 sites host a single reactor, others have two or more, and Vogtle stands out with four reactors. Public support for nuclear energy remains strong, with 91% of residents near plants backing it.
Many current nuclear sites could expand with new reactors like Small Modular Reactors (SMRs) or larger designs. For example, North Carolina’s Shearon Harris plant, originally designed for four reactors, runs just one. SMRs, which are smaller than 350 MW, are seen as a key to reducing costs through factory production. Their small size makes them useful for remote areas, military bases, and industries that rely on expensive diesel generators. Similarly, microreactors which are generally smaller than 50 MW are often used for the same purpose.
To succeed, SMR construction must maximize factory production. Additionally, reducing on-site construction will help lower costs and make nuclear energy more competitive.

The 3 Phases to Achieve Nuclear Liftoff by 2050
A Robust Orderbook
The first step to nuclear expansion is securing 5–10 reactor orders by 2025. This committed orderbook is key for suppliers to invest in manufacturing and reduce costs. Early orders will allow the industry to ramp up production without overloading the supply chain. Delaying these orders until 2030 would raise costs by over 50% and make it harder to hit 2050 decarbonization goals.
On-Time Project Delivery
After the initial demand, delivering the first projects on time and within budget is crucial. The nuclear industry must ensure each phase, from design to licensing, is done efficiently. Meeting construction deadlines will build confidence and prove that future reactors can be completed successfully.
Scaling the Industry
As demand grows, the nuclear industry must expand its workforce, supply chains, and fuel capacity. Reaching 200 GW by 2050 will require scaling up every part of the nuclear ecosystem, from components to spent-fuel management. This industrial growth is essential for supporting the long-term deployment of nuclear energy.

U.S. Nuclear Growth Requires Major Expansion in Uranium Supply Chain
The DOE has given utmost importance to the need to boost uranium supply to reach the goal of 300 GW of nuclear power. The uranium enrichment pathway looks like this:
The nuclear fuel supply chain has four key steps

Source: DOE report
Mining and Milling
The nation will need 55,000 – 75,000 metric tons (MT) of uranium (U3O8) each year to hit the 2050 target. Currently, the country only produces 2,000 MT annually and has procured 22,000 MT. In 2014, U.S. uranium production peaked at 2,263 MT. To meet future demand, the US will have to increase its production by about 71,000 MT annually.
Conversion Capacity
U.S. will require 70,000 to 95,000 MT of uranium hexafluoride (UF6) conversion capacity. Right now, the country has 10,400 MT of capacity. The Metropolis Works facility, the nation’s sole UF6 converter, reopened in July 2023 after a six-year shutdown. However, this restart alone will not be enough to meet rising demand.
Enrichment Needs
The U.S. needs to boost its uranium enrichment from its current 4.4 million separative work units (SWU) per year to between 45 and 55 million SWU to support 300 GW of nuclear capacity. Generation IV reactors require high-assay low-enriched uranium (HALEU), enriched to 19.75%. At present, the U.S. relies on a single HALEU facility, producing only 900 kg annually. The DOE is taking steps to create a domestic HALEU supply chain through programs like the HALEU Availability Program, which is backed by $700 million from the Inflation Reduction Act.
Fabrication
The U.S. must also increase its uranium fuel fabrication capacity to between 6,000 and 8,000 MTU annually to support 300 GW of nuclear capacity. Its current capacity stands at 4,200 MT. In addition, advanced reactors will need new fuel types, such as TRISO and metallic fuels. Companies like TerraPower and X-energy are leading projects to develop these advanced fuels. X-energy’s TRISO-X facility, set to begin operations in 2025, will help meet these demands.
International Cooperation
The U.S. leads the “Sapporo 5” coalition, which includes the U.K., France, Japan, and Canada. Together, they have pledged $4.2 billion to invest in nuclear fuel services, including enrichment and conversion. The U.S. has committed $3.42 billion to secure a stable nuclear fuel supply chain and is working closely with its partners to eliminate bottlenecks in the supply chain.
By strengthening its uranium supply chains and collaborating with global partners, the U.S. is positioning itself for significant nuclear growth while ensuring energy independence and a secure domestic supply.
U.S. Nuclear Restarts Spark Fresh Demand for Uranium Amid Tight Supply
In September, the U.S. nuclear sector received a significant boost from DOE to restart major reactors, creating fresh demand for uranium amid a tight global supply chain. These developments mark a clear shift toward nuclear growth in the nation.
S&P Global mentioned, Jonathan Hinze, president of the UxC nuclear fuel consultancy remarked,
“Each of these reactors will use up to 500,000 lb U3O8 annually, and that demand has yet to fully hit the market. While the incremental increase in demand is not that large, any additional fuel purchasing by utilities will likely be felt in the current market given very tight supply-demand fundamentals across the nuclear fuel cycle.”
On Sept. 30, the Biden administration approved a $1.52 billion conditional loan guarantee to restart the 800-MW Palisades nuclear plant in Covert, Michigan. Just days earlier, on Sept. 20, Constellation Energy Corp. announced plans to restart the Three Mile Island Unit 1 nuclear plant in Pennsylvania, partnering with Microsoft to power its data centers.
Uranium Prices Rise on Reactor Restarts
Pricing is a key factor in the nuclear energy comeback. According to S&P Global, spot uranium prices have only seen a slight rise since recent announcements, but the sector is now trending upward. The price has quadrupled from its late-2010s level, fueled by renewed interest in nuclear energy. After the 2011 Fukushima disaster, the uranium market slumped for years. However, prices soared past $100 per pound in early 2024, driven by improved investor confidence.
Recent reactor restarts mark a sharp turnaround for the U.S. nuclear sector, which saw 13 reactors close between 2013 and 2022. Analysts now see more potential for growth. CIBC analysts believe these restarts will further boost the uranium market, especially as the power-hungry AI industry increases demand for energy to run data centers.

Source: S&P Global
Will it Put Pressure on Uranium Supply?
S&P Global further analyzed the situation. They anticipate the revival of nuclear plants is expected to intensify uranium demand. Consequently, driving up prices and challenging supply chains. Scott Melbye, president of the Uranium Producers of America, pointed out that Constellation’s restart will cut into its nuclear fuel reserves, further tightening an already constrained market.
Currently, global geopolitical tensions have also impacted the nuclear fuel market. The ongoing Russia-Ukraine war has led to disruptions, with the U.S. banning enriched uranium imports from Russia in April 2023. While waivers allow some imports until 2028, the market remains under pressure as Russia considers retaliatory export cuts.
With more countries, including the U.S., committing to tripling nuclear power by 2050, the sector is poised for long-term growth. As nuclear energy regains momentum, it is positioned as a critical component in global efforts to reduce carbon emissions and combat climate change.
6 Reasons Why Nuclear Energy Will Rule the Decarbonized Future
Here are six important reasons nuclear energy plays a key role in the journey to net-zero emissions:
- Generates electricity with almost no carbon emissions, making it essential for reducing reliance on fossil fuels.
- Provides constant, reliable electricity, crucial for stabilizing the grid as renewable sources grow.
- Nuclear plants produce far more electricity per acre than solar or wind, making them ideal for regions with limited space.
- They create high-paying jobs and stimulate local economies, especially in regions like the U.S. Southeast.
- Supports industrial processes like hydrogen production, benefiting industries beyond just power generation.
- Requires fewer raw materials than renewables, reducing environmental impact and conserving critical resources.

In conclusion, nuclear energy will play a pivotal role in the U.S.’s transition to a cleaner, more resilient grid, supporting economic growth and reducing emissions.

Indigo Carbon Surpasses 2 Million Soil Carbon Credits in Landmark 1.1 Million Issuance
Indigo Carbon announced it has now passed 2 million metric tons of verified climate impact from U.S. croplands. The company reached the milestone after issuing its fifth U.S. “carbon crop.” The new issuance includes 1.1 million independently verified carbon credits issued through the Climate Action Reserve (CAR).
Indigo describes the milestone in its announcement as a sign that soil-based carbon programs can scale. It also points to rising corporate demand for credits that meet stricter quality rules.
Indigo’s latest issuance is important because it is linked to a major registry method that now carries an additional integrity label. Max DuBuisson, Head of Impact & Integrity, Indigo, remarked:
“Indigo continues to set the standard for high-integrity soil carbon removals that corporate buyers can trust. Soil carbon is uniquely positioned to scale as a climate solution because it captures and stores carbon while also improving water conservation and crop resilience. By combining world-class science and technology with farmer-driven practice change, we’re proving that agricultural soil carbon is an immediate, durable, high-integrity solution capable of helping global companies meet their climate commitments.”
Inside the 1.1M Credit Issuance and CCP Label
Indigo says its fifth issuance includes 1.1 million carbon credits verified and issued through CAR. These credits come from Indigo’s U.S. soil carbon project, listed on the Climate Action Reserve under the Soil Enrichment Protocol (SEP) Version 1.1.
CAR’s SEP is designed to quantify and verify farm practices that increase soil carbon and reduce net emissions. It covers changes in soil carbon storage and also includes reductions in certain greenhouse gases tied to farm management.
CAR’s SEP Version 1.1 has the ICVCM Core Carbon Principles (CCP) label. This means the method meets the standards set by the CCP framework.

Indigo’s disclosures also describe long-term monitoring rules. The company reports that its U.S. project includes 100 years of project-level monitoring after credit issuance, in line with CAR requirements. This mix of independent verification, registry issuance, and long monitoring periods is central to the case Indigo makes for credit quality.
Breaking Down the 2 Million Ton Milestone
Indigo says its total verified impact now exceeds 2 million metric tons of carbon removals and reductions across U.S. croplands.
In carbon markets, one credit equals one metric ton of CO₂ equivalent. Indigo’s latest issuance is very large by soil carbon standards. It also builds on earlier “carbon crop” issuances.
Indigo’s project disclosures include a quantified impact figure for its U.S. project. The company reports 927,367 tCO₂e reduced or removed through Dec. 31, 2023, for the project listed as CAR1459.

Indigo announced it has saved 118 billion gallons of water. It has also paid farmers $40 million through its programs so far. These points matter because many buyers now look beyond carbon totals. They also want evidence of farmer payments, monitoring rules, and co-benefits like water conservation.
Corporate Demand Shifts Toward Verified Removals
One reason soil carbon is getting more attention is the growing demand from buyers for removals. Many companies now focus more on carbon removal credits, not only avoidance credits.
Indigo’s largest recent buyer example is Microsoft. In January 2026, the carbon ag company announced a 12-year agreement under which Microsoft will purchase 2.85 million soil carbon removal credits from them.
- The soil carbon producer said this is Microsoft’s third transaction with the company, following purchases of 40,000 tonnes in 2024 and 60,000 tonnes in 2025.
The tech giant’s purchases show how corporate buyers may use long-term offtake deals to secure future supply of credits. This matters for soil carbon programs because credits are typically generated over multiple years. And they also depend on practice changes and verification cycles.
Indigo also says its program works across eight million acres, which signals how it is trying to scale participation across U.S. farms.
Soil Carbon Credits: Market Trends and Forecast
Soil carbon credits are gaining attention as buyers shift toward higher-quality credits and clearer verification rules. Ecosystem Marketplace reports that the voluntary carbon market is entering a new phase. This phase emphasizes integrity, even though trading activity has slowed down.
In its 2025 market update, Ecosystem Marketplace noted a 25% drop in transaction volumes. This decline shows lower liquidity as buyers are becoming more selective.

At the same time, demand for higher-quality credits is rising. Sylvera’s State of Carbon Credits 2025 reported that retirements dropped to 168 million credits in 2025, a 4.5% decrease.
Still, the market value climbed to US$1.04 billion due to rising prices. It also found that higher-rated credits (BBB+) made up 31% of retirements, and traded at higher average prices than lower-rated supply.
For soil carbon, buyers are also watching methodology quality. The ICVCM has approved two sustainable agriculture methods as CCP-approved. These are the Climate Action Reserve’s Soil Enrichment Protocol v1.1 and Verra’s VM0042. This can support stronger buyer confidence and may increase demand for soil credits that meet CCP rules.
Looking ahead, Sylvera projects compliance-linked demand will keep growing and could exceed voluntary demand by 2027. That trend may favor credits with stronger verification and compliance alignment, including higher-integrity soil carbon credits. However, integrity issues still occur, and this is where Indigo comes in.
Tackling Permanence and MRV Head-On
Soil carbon credits face a key challenge: carbon stored in soil can be reversed. A drought, land use change, or a shift in farm practices can reduce stored carbon.
This is why monitoring and reversal rules matter. CAR’s protocol is built to quantify, monitor, report, and verify practices that increase soil carbon storage.
Indigo’s project disclosure notes that projects are monitored for 100 years after they are issued. This shows the durability rules tied to their method and registry approach.
The company also positions its program as “outcome-based,” meaning it pays for verified carbon outcomes rather than paying only for adopting a practice. This messaging is designed to reassure buyers that credits are not only modeled. It stresses verification and the registry process.
A Scale Test for High-Integrity Soil Carbon
Indigo’s fifth issuance lands at a time when voluntary carbon markets are placing more weight on integrity labels and independent verification.
Two parts stand out:
- First, volume. An issuance of 1.1 million credits through a registry is large for an agricultural soil carbon program.
- Second, method approval. CAR’s SEP Version 1.1 carries the ICVCM CCP label, which is meant to signal alignment with a global integrity benchmark.
That combination may make it easier for corporate buyers to justify purchases internally. Many companies now face stronger scrutiny from auditors, regulators, investors, and civil society groups.
At the same time, more supply does not automatically mean market confidence rises. Buyers still assess risks such as permanence, additionality, and measurement uncertainty.
Even so, the milestone shows how fast some parts of the removals market are trying to scale. Large buyers are also helping drive this shift through multi-year offtake deals, like the Microsoft agreement for 2.85 million credits.
For Indigo, the new issuance supports its claim that soil carbon is moving from small pilot volumes toward larger, repeatable issuances. For the market, it adds another real-world data point: a major soil carbon program has now completed five issuance cycles and passed 2 million metric tons of verified climate impact.

Meta, Amazon, Google, and Microsoft Dominate Clean Energy Deals as Global Buying Slips in 2025
For nearly a decade, global companies have been racing to buy clean energy from wind farms, solar parks, and other green power projects. But 2025 marked the first decline in this trend in almost ten years — a surprising shift that signals a changing landscape for corporate sustainability.
The latest report from BloombergNEF (BNEF) shows that corporate clean energy purchasing dropped about 10% in 2025, falling from roughly 62.2 gigawatts (GW) in 2024 to 55.9 GW last year.
Let’s break down why this happened, what it means, and how the market could evolve in the coming years.
Clean Energy Buying: The Big Picture
Corporate clean energy buying usually happens through power purchase agreements (PPAs). They are long-term contracts where companies agree to buy electricity directly from renewable energy projects, often wind or solar farms.
For years, this was one of the fastest-growing parts of the clean energy market. Companies like Google, Amazon, Meta, and Microsoft drove most of the demand, helping build huge amounts of renewable capacity. But 2025 interrupted that streak.
Even though 55.9 GW is still one of the largest annual totals ever, the fact that it is lower than the year before shows a real shift in how companies approach renewable energy deals.
Why Corporate Clean Energy Buying Fell
There are several reasons why corporate clean energy buying slowed in 2025:
Corporate buyers are sensitive to electricity market rules and government policies. In many regions, uncertain policy environments made it harder to finalize long-term clean energy contracts. In the United States, for example, uncertainty about future clean energy incentives and carbon accounting standards caused many smaller corporations to hold off on signing new deals.
In some power markets, especially in parts of Europe, there were long hours of negative electricity prices. This happens when supply exceeds demand and power becomes so cheap that producers pay buyers to take it.
These price swings make standalone solar and wind contracts less attractive, especially for companies that want predictable, long-term value from their clean energy purchases.

Dominance of Big Tech
Another key point in the BloombergNEF findings is that the market is becoming more concentrated. As said before, four major tech firms, like Meta, Amazon, Google, and Microsoft, signed nearly half of all clean energy deals in 2025.
Meta and Amazon alone contracted over 20 GW of clean power last year, including deals that cover not just solar or wind, but also nuclear power — something unusual in past corporate PPA markets.
While this heavy concentration helps maintain volume, it also means that smaller companies are scaling back, which lowers the total number of buyers and contributes to the overall slowdown.

Regional Differences: Where Things Slowed and Where They Didn’t
Corporate clean energy markets didn’t all move in the same direction last year. Bloomberg’s data shows clear regional patterns:
United States
The U.S. remained the largest single market for corporate clean energy deals, signing a record 29.5 GW of commitments. Much of this came from major technology companies looking to match their growing electricity needs with zero-carbon power sources.
Yet despite these high numbers, the number of unique corporate buyers in the U.S. dropped by about 51%, as many smaller firms pulled back from signing new PPAs.
Europe, Middle East & Africa (EMEA)
In the EMEA region, corporate PPAs fell around 13% in 2025, slipping back to levels closer to 2023. In Europe, in particular, rising negative prices and unstable policy conditions discouraged many new deals.
Asia Pacific
Asia had a mixed story. Some markets like Japan and Malaysia continued to attract corporate clean energy buyers, thanks to mature PPA markets and supportive regulations. But slower activity in countries like India and South Korea contributed to a drop in total volumes in the region.

The Rise of Hybrid and Firm Power Deals
One interesting trend that emerged in 2025 is that companies are looking beyond just wind and solar. Because of the limitations with standalone renewable deals, many buyers are now exploring hybrid power contracts that mix renewables with storage, or even nuclear and geothermal sources.
Hybrid deals like solar paired with battery storage give companies more reliable power and help manage price and supply risks. BloombergNEF tracked nearly 6 GW of these hybrid agreements in 2025, and expects this share to grow.
- According to a report by SEIA and Benchmark Mineral Intelligence, the United States added a record 28 gigawatts (GW) / 57 gigawatt-hours (GWh) of battery energy storage systems (BESS) in 2025. It reflected a 29% year-over-year increase.
Cheaper battery costs are part of this trend. Recent data shows that the cost of four-hour battery storage projects fell about 27% in 2025, reaching record lows. This makes storage-based renewable contracts more financially compelling.

Big Companies Still Push the Market
Even with the overall slowdown, corporate clean energy buying remains strong, especially among large technology firms.
In fact, while smaller companies took a step back, the major tech buyers helped keep total volumes near all-time highs. In other words, the market didn’t crash; it just shifted shape.
This becomes even clearer when we look at individual company progress. Microsoft reported recently that it now matches 100% of its global electricity use with renewable energy, an achievement that required decades of energy contracts and partnerships.
The Clean Energy Market Is Resetting, Not Retreating
The IEA projects that renewables will provide 36% of global electricity in 2026. This shows that the energy transition is moving forward, even if corporate clean energy purchases dipped in 2025. The slowdown does not signal failure. Instead, it reflects a market that is adapting as companies, technologies, policies, and economics evolve together.

Growth in corporate renewable deals is not always steady. A single year of lower volumes does not erase the gains of the past decade. Instead, it highlights the natural adjustments markets go through as strategies shift and conditions change.
In this transitioning phase, policy and regulation remain critical. Clear rules, incentives, and supportive frameworks encourage smaller companies to participate. Additionally, regions that provide stability, such as parts of the Asia Pacific, are seeing continued growth in corporate clean energy demand.
In conclusion, even with the dip in 2025, corporate renewable energy purchasing is far larger than it was ten years ago. The market is shifting rather than shrinking, and companies continue to find ways to power growth with clean energy. This slowdown may serve as a wake-up call, encouraging smarter, more flexible strategies that can sustain the energy transition for years to come.
