What Nephin Renewable Gas does

Nephin Renewable Gas (NRG) is an Irish renewable energy company, headquartered in Tipperary Town and operating as a dedicated biomethane subsidiary of Nephin Energy. Founded in February 2024 and backed by CPP Investments (Canada Pension Plan Investment Board) as cornerstone investor, the company develops, builds, and will operate anaerobic digestion (AD) plants that convert agricultural waste into renewable biomethane for injection into the Irish gas grid and supply to industrial, commercial, and domestic heat users.

The company's core product is grid-injectable biomethane produced through anaerobic digestion of agricultural feedstocks (principally livestock manure, slurry, and energy crops). Its flagship project is the Ballinrobe plant in County Mayo, which broke ground in September 2025 and is targeted to become Ireland's first commercial-scale agricultural biomethane facility when it reaches commercial operation in 2027. Technical differentiation rests on the management team's claimed 100+ years of collective AD experience, with the Managing Director having personally delivered more than 40 AD projects. The company is also advancing a development pipeline targeting up to 1.5 TWh of biomethane output over a 5–7 year horizon.

NRG's business model combines long-term feedstock supply agreements with Irish farmers, AD plant operations, grid injection via Gas Networks Ireland (under a November 2024 MoU — the first signed by any biomethane developer in Ireland), and biomethane offtake to licensed gas suppliers, anchored by the September 2025 Flogas (DCC plc) agreement — described as the largest domestic biomethane offtake in Ireland. Revenue will therefore be driven by long-duration take-or-pay-style offtake contracts and any government Renewable Heat Incentive / National Biomethane Strategy support payments once plants become operational; the company is currently pre-revenue with all material commercial output scheduled for 2027 onward.

Revenue model

1. Biomethane Sales: Sale of biomethane produced from anaerobic digestion plants to offtake partners. Biomethane is sold as carbon-neutral renewable gas directly to the gas grid and commercial customers.
2. Agricultural Feedstock Purchase: Purchase of agricultural waste including manures and slurries from farmers, providing them with reliable long-term income while acquiring raw materials for biomethane production
3. Biofertiliser Sales: Sale of digestate by-product from anaerobic digestion process as sustainable fertiliser to displace imported fossil fuel derived fertiliser

Core offering

Nephin Renewable Gas develops and operates biomethane production projects based on anaerobic digestion. It processes agricultural manures, slurries, and food waste into renewable natural gas for injection into Ireland's gas grid, with digestate produced for use as biofertiliser.

Product overview

Nephin Renewable Gas (NRG) is a biomethane development company offering a portfolio of renewable energy products and services. The core product is biomethane produced via anaerobic digestion (AD) of agricultural waste, which is injected into Ireland's gas network. The flagship Ballinrobe Plant represents Ireland's first commercial-scale agri-based biomethane facility. Byproducts include biofertiliser (digestate) for agricultural use and biogenic CO2 for industrial applications. The company provides gas network injection services through its partnership with Gas Networks Ireland, and operates a farm feedstock partnership model where agricultural waste is sourced from local farmers under long-term supply agreements. The company aims to develop up to 1.5 TWh of biomethane capacity across multiple AD plants nationwide within 5-7 years.

• FlogascoreStrategic or Co-development Partner · 11 September 2025Landmark biomethane offtake agreement signed - largest domestic biomethane agreement in Ireland to date. Flogas will be the offtake partner for renewable gas produced by three anaerobic digestion plants in Nephin's development pipeline. The three plants will deliver over 250 GWh of sustainable Irish-produced biomethane annually - enough to heat over 38,000 homes. Flogas is a DCC business and Ireland's first energy supplier to secure indigenous biomethane (2020).

Regional players

• Severn Trent Green Power: UK-based AD operator (subsidiary of Severn Trent plc) running multiple AD plants primarily on water utility sludge and food waste. Comparable technology stack and offtake to gas/electricity, but geographically concentrated in the UK rather than Ireland.

Broad incumbents

• Nature Energy (Shell Nature Energy): Europe's largest biomethane producer (acquired by Shell in 2022) operating a portfolio of large-scale AD plants across Denmark and internationally. Provides a benchmark for scaled biomethane economics and infrastructure roll-out relevant to NRG's growth trajectory.

Others

• AB Energy: European CHP/biogas equipment provider and co-sponsor of Biomethane Day Ireland with NRG. Adjacent enabling relationship—supplies engines/integration for AD plants—but not a direct competitor in biomethane production.
