Here are the key risks to OPAL Fuels' business:

1. Exposure to Regulatory and Policy Changes: OPAL Fuels' profitability is heavily dependent on government incentives and environmental credit programs, such as D3 Renewable Identification Numbers (RINs) and Low Carbon Fuel Standard (LCFS) credits, which constitute a significant portion of the company's revenue. Any adverse changes in regulations, reductions in incentive values, or shifts in governmental policy (e.g., under a new administration) could materially impact the market price of these credits, directly affecting OPAL Fuels' revenue and margins.

2. Commodity Price Volatility: The company is susceptible to the volatility of commodity prices, including natural gas, diesel, and the aforementioned environmental credits. Fluctuations in these prices can impact the cost of operations, the competitiveness of renewable natural gas against conventional fuels, and the overall value of OPAL Fuels' products and environmental attributes, leading to potential instability in future earnings.

3. Capital Intensity, Project Execution, and Operational Dependencies: OPAL Fuels' growth strategy relies on significant capital investments for developing and expanding its RNG production facilities and fueling station network. The company has experienced historical operating losses, maintains a substantial level of debt, and has expressed a need for liquidity, raising risks of potential capital dilution. Furthermore, delays in project development, increased construction costs, operational hazards inherent in handling flammable materials at RNG facilities, and the company's reliance on agreements with third-party feedstock providers (like landfill and dairy farm owners) and utility companies pose significant operational and financial risks. Disruptions in any of these areas could hinder growth plans, affect cash flows, and impact overall profitability.

The clear emerging threat for OPAL Fuels is the rapid advancement and increasing adoption of **battery-electric heavy-duty trucks**. As major manufacturers such as Tesla, Daimler Truck, and Volvo Trucks continue to develop, produce, and deploy electric semi-trucks, the market for internal combustion engine heavy-duty trucks, including those powered by renewable natural gas (RNG), faces a direct challenge. If battery technology improves in terms of range, charging speed, and cost-effectiveness, and as charging infrastructure expands, battery-electric trucks could significantly reduce the long-term demand for RNG and natural gas fueling stations, directly undermining OPAL Fuels' core business.

OPAL Fuels Inc. operates in several addressable markets related to renewable natural gas (RNG) and alternative fueling infrastructure, primarily for the heavy-duty truck market in North America.

Renewable Natural Gas (RNG) Production and Distribution

The global renewable natural gas (RNG) market was estimated at approximately USD 15.17 billion in 2024 and is projected to grow to about USD 30.13 billion by 2033, demonstrating a Compound Annual Growth Rate (CAGR) of 8.0% from 2025 to 2033. North America, a key region for OPAL Fuels, held the largest share of the global RNG market, approximately 45%, in 2024. Within this market, the transportation fuel segment, which includes heavy-duty trucking, constituted the largest application share, about 56%, in 2024. In the U.S., renewable natural gas (RNG) and compressed natural gas (CNG) currently serve only 2% of the heavy-duty trucking market, indicating a significant addressable growth opportunity. The North American RNG market capacity is projected to reach 604 million cubic feet per day (mmcfd) in 2025.

Natural Gas Fueling Stations

The global natural gas refueling stations market is projected to reach USD 4.1 billion by 2034, growing from USD 2.1 billion in 2024 at a CAGR of 6.8%. North America represents a significant market for natural gas fueling stations, with the U.S. expected to contribute substantially to the regional market's expansion due to continuous investments in infrastructure and technological advancements. As of 2023, the United States had over 700 public compressed natural gas (CNG) fueling stations and approximately 50 liquefied natural gas (LNG) fueling stations, mainly serving the long-haul trucking industry.

Hydrogen Fueling Stations

The global hydrogen fueling station market size was approximately USD 500.74 million in 2025 and is predicted to grow to about USD 2,271.60 million by 2035, with a CAGR of 16.32% from 2026 to 2035. The U.S. hydrogen fueling station market specifically generated USD 83.1 million in revenue in 2024 and is anticipated to reach USD 458.2 million by 2030, exhibiting a robust CAGR of 32.4% from 2025 to 2030. North America held a dominant share of the global market, accounting for 42.14% in 2025.

OPAL Fuels Inc. (OPAL) is expected to drive future revenue growth over the next 2-3 years through several key initiatives and market dynamics:

1. Increased Renewable Natural Gas (RNG) Production: The company anticipates continued double-digit growth in RNG production, stemming from new facilities coming online and enhanced operational efficiencies at existing plants. For 2026, OPAL Fuels targets RNG production between 5.4 million and 5.8 million MMBtu.
2. Expansion of Fuel Station Services and New Fleet Adoption: OPAL Fuels is actively expanding its network of owned fueling stations, which reached 61 by the end of 2025. The company expects improving macro conditions to stimulate deferred truck purchases by fleets, leading to increased adoption of Compressed Natural Gas (CNG) and RNG in heavy-duty trucking, particularly in 2027 and beyond, with 2026 as a pivotal year.
3. Benefit from 45Z Tax Credits: The extension of the 45Z tax credit through 2029 provides crucial policy stability and financial support for RNG project economics. OPAL Fuels' 2026 guidance includes an estimated $15 million to $20 million from these credits, directly contributing to profitability and revenue.
4. Operational Improvements and Higher Plant Utilization: Ongoing enhancements in gas collection, plant efficiencies, and operational teams are projected to drive incremental production growth from existing RNG assets. The company aims to increase plant utilization towards a target of 85% to 86%.
5. Strategic Project Pipeline and Capital Investment: OPAL Fuels maintains a robust pipeline of new project opportunities, including biogas rights and renewable power conversion projects. The company's strengthened liquidity position, supported by new financing facilities, enables disciplined capital allocation for further expansion across its integrated RNG value chain.
