Rice Acquisition Corp. II (RONI): history, ownership, mission, how it works & makes money

Curious how a 2021 SPAC transformed into a publicly traded clean-energy force? Rice Acquisition Corp. II (RONI) - formed as a special purpose acquisition company in 2021 - announced in December 2022 a definitive merger with NET Power and completed that transaction in June 2023, launching NET Power Inc. on the NYSE under the tickers NPWR and NPWR WS; the deal created a combined enterprise valued at roughly $1.5 billion with market capitalization topping $2 billion and delivered over $675 million in gross proceeds (including about $135 million from RONI's trust and ~$540 million in PIPE commitments) to accelerate commercialization of NET Power's nearly 100%-CO₂-capturing Allam Cycle technology, backed by strategic partners (Occidental, Baker Hughes, Constellation, 8 Rivers) who rolled their equity into the combined company, the Rice family and affiliates increasing their PIPE stake to $125 million (with an additional $25 million commitment) and Occidental providing a $10 million interim loan - all to fund modular, scalable plant deployments slated to begin in 2026 and monetize through electricity sales, licensing, PPAs and strategic partnerships.

Rice Acquisition Corp. II (RONI): Intro

Rice Acquisition Corp. II (RONI) was formed in 2021 as a special purpose acquisition company (SPAC) targeting the energy sector. In December 2022 RONI announced a definitive agreement to combine with NET Power - a clean-energy technology company developing low-emission, natural gas-based power generation using the Allam-Fetvedt Cycle. The business combination closed in June 2023, creating NET Power Inc.; its Class A common stock and warrants began trading on the New York Stock Exchange under NPWR and NPWR WS.

• Incorporation: 2021 as a SPAC focused on energy.
• Combination announcement: December 2022 with NET Power.
• Transaction close: June 2023; public listing as NET Power Inc. (NPWR / NPWR WS).
• Initial enterprise value at closing: ~ $1.5 billion.
• Market capitalization at combination: exceeded $2.0 billion.

The merger provided NET Power with significant capital to scale its patented zero-emissions-ready power technology and fund initial plant deliveries expected to begin in 2026.

Ownership and Capital Structure

• Former RONI public shareholders converted into holders of NET Power equity and/or had redemption options at the SPAC close.
• PIPE investors contributed approximately $540 million of fresh equity - a mix of strategic and financial backers - providing cornerstone support.
• Post-transaction capitalization reflected institutional PIPE holders, sponsor roll and public float; specific post-close ownership percentages varied by class and warrant conversion.

Mission and Strategic Rationale

NET Power's stated mission is to commercialize a low-emission, low-cost power platform capable of near-zero CO2 emissions from natural gas power generation, with potential applications for hydrogen and industrial heat. The RONI combination aimed to:

• Accelerate deployment of NET Power's Allam-Fetvedt Cycle technology.
• Fund construction and early fleet rollouts (initial plants targeted for 2026 delivery).
• Position the combined company to capture market share in decarbonizing baseload and industrial power.

How It Works - The Business and Technology Model

NET Power commercializes a proprietary thermodynamic cycle that combusts natural gas with pure oxygen and captures CO2 in a supercritical state while producing electricity. Key commercial elements include:

• Technology licensing and EPC (engineering-procurement-construction) project development.
• Sale or long-term contracting (power purchase agreements) of power output to utilities/industrial customers.
• Potential for CO2 utilization or storage value streams when integrated with industrial customers or sequestration.

How It Makes Money - Financial Path to Commercialization

• Near-term: use merger proceeds (> $675M) to complete demonstration sites, finalize supply chain, and secure initial customer PPAs.
• Medium-term (2026+): monetize via EPC projects, licensing, and long-term power sales as plants are delivered and commissioned.
• Long-term: scale through repeatable modular plant deliveries, expanded licensing, and potential CO2-related revenue streams; margins expected to improve as technology matures and supply chain scales.

Rice Acquisition Corp. II (RONI): Mission and Values

• Fuel and oxidant combustion: Natural gas combusted with oxygen produces a high-pressure, high-temperature stream rich in CO₂ and water.
• sCO₂ working fluid: Combustion products are cooled and pressurized to supercritical conditions; sCO₂ drives a turbine directly, avoiding steam turbines.
• Closed-loop CO₂ recycle: After expansion, CO₂ is cooled, condensed (water removed), compressed and recycled into the combustor-resulting in an inherently concentrated CO₂ capture stream.
• Pure CO₂ product: The near-pure CO₂ stream can be compressed for utilization (e.g., enhanced oil recovery) or transported for permanent geologic storage.

• Power sales - dispatchable baseload or flexible electricity sold into wholesale/retail markets or under power purchase agreements (PPAs).
• Carbon commodity value - captured CO₂ can be monetized via enhanced oil recovery (EOR) contracts or sold/credited under emerging carbon marketplaces and tax-incentive regimes (e.g., 45Q-like credits where applicable).
• Equipment & licensing - modular plant packages, proprietary turbomachinery and process licensing provide recurring revenue streams and margin from manufacturing/installation.
• O&M and service contracts - long-term operations, maintenance and upgrade services tied to installed fleet.

• Modular scalability - factory-fabricated modules reduce on-site construction time and cost, enabling siting near CO₂ storage hubs or industrial customers.
• Partner ecosystem - strategic collaborations with engineering, EPC and financiers accelerate commercialization and de-risk first-of-a-kind (FOAK) to nth-of-a-kind (NOAK) transitions.
• Policy alignment - projects are structured to capture value from carbon credit/tax-incentive regimes and EOR markets, improving project IRRs versus conventional gas plants.

• Capital support - RONI's role is to provide growth capital and public-market access to accelerate FOAK-to-commercial rollouts of technologies like NET Power's Allam Cycle.
• Value creation - by backing scalable low‑carbon power systems with identifiable revenue models (power + carbon), RONI aims to capture upside as deployments transition to repeatable commercial scale.
• Investor alignment - structuring deals that align equity upside with meaningful decarbonization metrics and long-term cash flows.

Rice Acquisition Corp. II (RONI): How It Works
