Nephin Energy Limited

What Nephin Energy Limited does

Nephin Energy Limited is Ireland's largest domestic natural gas producer, holding a 43.5% non-operating interest in the Corrib Gas Field located 83 kilometres off Ireland's northwest coast in 350 metres of water depth. The Corrib field supplies up to 30% of Ireland's daily gas needs and constitutes 100% of Ireland's domestic natural gas production. Gas is processed at the Bellanaboy Bridge Gas Terminal and transmitted via a 90km pipeline to the national gas grid operated by Gas Networks Ireland, with Vermilion Energy (56.5% interest) acting as field operator. The company is a wholly-owned subsidiary of Canada Pension Plan Investment Board (CPP Investments), which acquired Shell's 45% interest for $1.23 billion in 2017 and subsequently built out Nephin Energy to hold the asset.

The company is executing a strategic pivot from a single-asset natural gas holding company into a multi-vector renewable energy platform. In February 2024, Nephin launched Nephin Renewable Gas (NRG), a biomethane subsidiary headquartered in Tipperary Town, focused on producing renewable gas from agricultural waste through anaerobic digestion. Construction began in September 2025 on Ireland's largest agri-based biomethane plant at Ballinrobe, County Mayo, processing 90,000 tonnes of farm waste annually to generate over 85 GWh of biomethane, with three plants in the pipeline delivering 250+ GWh annually under a landmark offtake agreement with Flogas (DCC plc). In February 2026, the Corrib Joint Venture signed a Strategic Collaboration Agreement with Gas Networks Ireland to explore green hydrogen production at Bellanaboy, leveraging existing infrastructure and Mayo's wind resources.

Nephin operates with a small team (1-10 employees) and is led by Group CEO Tom O'Brien, with a board drawing deep E&P expertise from Shell, Vermilion, Tullow, and CPP Investments senior leadership. The revenue model is transaction-based: natural gas sold to the national grid and energy suppliers, and biomethane locked in via multi-year offtake agreements with Flogas and grid injection partnerships with Gas Networks Ireland. The company's strategic intent, articulated as 'growing in Ireland and Europe through the acquisition of material interests in assets across the energy spectrum,' is enabled by patient capital from CPP Investments (CAD $780.7 billion in net assets as of December 2025). The Corrib interest provides stable cash flow funding the transition into biomethane and hydrogen, positioning Nephin as a central player in Ireland's energy transition strategy.

Broad incumbents

• Drax Group: UK-listed renewable energy generator with significant biomass power generation and an emerging bioenergy with carbon capture and storage (BECCS) business. Comparable as a broader incumbent in renewable gas/bioenergy infrastructure converting biological feedstocks into grid-scale energy.
• Equinor: Norway-headquartered Equinor is a major European natural gas producer and active developer of offshore wind and hydrogen. Its combination of upstream gas production with renewable energy diversification parallels Nephin's Corrib/hydrogen/biomethane strategy, though at much larger scale and across multiple geographies.
• Eni: Italian integrated energy major with significant natural gas production and an established biomethane and agricultural feedstock business (Eni Rewind, Agri-feedstock partnerships). Comparable as a European gas major building a renewable gas portfolio through anaerobic digestion and circular economy initiatives.
• BP: Global supermajor with natural gas production and growing biomethane and bioenergy investments. BP's gas + renewables transition strategy and integrated energy portfolio broadly parallels Nephin's positioning as a gas asset holder pivoting to renewable gas.
• Shell: Shell was the original operator of Corrib, divesting its 45% stake to CPP Investments (Nephin) in 2017 for $1.23B. As a global supermajor with major natural gas and emerging biomethane/hydrogen businesses, Shell is a broad incumbent in the same upstream gas + renewable energy transition space.
• TotalEnergies: Global integrated energy company with extensive natural gas production and a multi-billion-euro biomethane investment program (acquisitions of biogas players in Europe). Comparable to Nephin as a large gas producer scaling into biomethane and grid-compatible renewable gas.

Direct peers

• Vermilion Energy: Vermilion operates the Corrib Gas Field with a 56.5% operated interest and is Nephin's direct JV partner in the same asset. It is a publicly traded Canadian-incorporated international gas and oil producer with comparable upstream gas operations across North America, Europe, and Australia, making it the most direct operational comparable.
• GreenGas: GreenGas is an Irish biomethane producer developing anaerobic digestion plants across Ireland, directly comparable to Nephin Renewable Gas's biomethane development pipeline. Both target agricultural waste feedstock, grid injection via Gas Networks Ireland, and Proof of Sustainability-certified renewable gas for Irish industrial and heat customers.

Emerging players

• Future Biogas: UK-based anaerobic digestion and biomethane producer operating multiple AD plants supplying renewable gas to the UK gas grid. Comparable to Nephin Renewable Gas in feedstock sourcing, AD technology, and offtake agreements with energy suppliers, though focused on the UK rather than Irish market.
• Bright Renewables: Dutch biomethane technology provider and AD plant operator with comparable anaerobic digestion technology and grid injection partnerships. Represents an emerging player in the European biomethane infrastructure space with overlapping technology and customer base.
