Ren-Gas

What Ren-Gas does

Ren-Gas (Nordic Ren-Gas Oy) is a Finnish clean energy company founded in 2021 and headquartered in Espoo that develops, builds, and will operate a decentralized portfolio of Power-to-Gas (P2G) plants producing RFNBO-compliant e-methane. Its core process electrolyzes water using renewable Finnish electricity to produce green hydrogen, which is then combined with biogenic CO2 captured from partner energy plants through catalytic methanation to yield synthetic renewable methane; waste heat from the process is recovered for sale to local district heating networks. The company operates a platform-plus-production model, anchored by its proprietary NRG SIMO simulation and optimization platform used for project bankability and the OMO centralized operations and maintenance framework for multi-site control. The portfolio under development exceeds 700 MW of electrolysis capacity across sites in Tampere, Lahti, Kotka, Kerava, Mikkeli, and Pori, with first commercial operations targeted from 2028.

The business model is B2B enterprise sales built on long-term offtake agreements and co-development partnerships. Primary customers are heavy-duty road transport and maritime transport operators requiring RFNBO-certified fuel to comply with binding EU RED III climate legislation effective from 2028, supplemented by sales to district heating networks and hard-to-abate industrial sectors. Gasum is an anchor offtake counterparty for up to 800 GWh of e-methane annually from two plants starting 2026. Revenue streams include long-term e-methane offtake contracts, optional hydrogen sales, and transaction-based district heat sales enabled by sector integration with municipal energy partners. Pricing is not publicly disclosed and is negotiated through multi-year volume-committed contracts, with German RFNBO market values projected above EUR 600/MWh.

Capital structure combines venture equity (Taaleri, Tesi, Allianz Capital Partners, Suomen Tavara ja Raha Oy), public grants (EUR 42M EU Innovation Fund for Kotka, EUR 45M Hydrogen Bank Auction for Lahti, EUR 28M and EUR 46M Finnish Ministry of Employment and the Economy support for Lahti and Tampere, EUR 1.5M Business Finland R&D loan), and institutional debt (EUR 230M European Investment Bank framework). The company remains pre-revenue, with all sites in development or pre-construction, transitioning to execution phase through 2026-2027 ahead of first commercial fuel sales from 2028-2029.

Core offering

Ren-Gas develops, builds and operates industrial-scale Power-to-Gas plants in Finland that produce RFNBO-certified renewable e-methane by combining green hydrogen (from water electrolysis using renewable electricity) with captured biogenic CO2 through catalytic methanation. The e-methane is delivered to European markets via existing gas infrastructure for use as a drop-in fuel in heavy-duty road and maritime transport, while waste heat from production is supplied to district heating networks.

Product overview

Ren-Gas is a Finnish energy company that operates a platform-plus-production model for delivering RFNBO-compliant e-methane to European markets. The core offering centers on E-methane (RFNBO Fuel), a synthetic renewable gas produced at Power-to-Gas Plants through methanation combining Green Hydrogen (produced via electrolysis from wind power) with biogenic CO2. The proprietary NRG SIMO Optimization Platform enables project bankability and real-time operational optimization across the plant network. District Heating is recovered as a valuable byproduct from the production process and supplied to local district heating networks. The integrated system allows Ren-Gas to deliver reliable, cost-effective, and scalable green fuel for heavy transport and shipping while maximizing efficiency through sector integration.

Functional benefit

Products and services

• E-methane (RFNBO Fuel) Synthetic, renewable methane produced by combining green hydrogen with biogenic carbon dioxide through catalytic methanation. It is an RFNBO-compliant drop-in fuel that can be distributed through existing European gas infrastructure and used in heavy-duty road and maritime transport to meet EU RED III mandates.
• Green Hydrogen Hydrogen produced by electrolysis of water using renewable Finnish wind electricity. It is the primary feedstock for e-methane production and can be sold separately as a green hydrogen product to industrial and mobility customers.
• District Heating (Carbon Dioxide-Free) Carbon dioxide-free heating produced by recovering waste heat from e-methane and hydrogen production processes. Supplied to local district heating networks (e.g., Keravan Energia, Tampereen Energia, Lahti Energia) to replace combustion-based heat production.
