OX2, Sodra and TES advance e-NG project into pre-FEED
OX2 and Södra, together with the e-NG project development company TES, announced that they are advancing their development plans for an e-NG (electric natural gas) facility at the Värö peninsula in Varberg, Sweden, by entering the Pre-Front-End Engineering Design (Pre-FEED) phase. The decision follows the signing of a Letter of Intent in January 2025 and the successful completion of an initial feasibility study assessing the technical and commercial viability of the concept.
Sweden imports significant quantities of fossil natural gas and biogas to supply chemical and industrial companies that depend on gas in their processes, primarily via pipeline from Denmark, with fossil-based natural gas still representing the lion’s share of this energy mix. The Värö e-NG project can materially support the Swedish energy transition, economy, its energy security and resilience.
The facility is designed to produce 1.2 TWh of e-NG (e-methane) annually. e-NG is produced capturing biogenic CO₂ from Södra’s pulp mill at Värö and combining it with hydrogen produced onsite using renewable electricity. With 1.2 TWh of e‑NG, the share of Swedish-produced fossil‑free gas in the Swedish gas grid would increase significantly, representing more than a fourfold increase in domestic production of fossil‑free gas.
The Pre-FEED phase which will be carried out over a one-year period, is partly supported by SEK 16.8 million (~€1.6 million) in funding from the Industrial leap (Industriklivet), the Swedish Energy Agency’s program for industrial decarbonization which is part of the EU Recovery and Resilience Facility (RRF) and Next Generation EU. The funding will form approximately 50% of the Pre-FEED and development costs.
During the Pre-FEED phase, the partnership will draw up technical designs, evaluate the potential for integration with Södra’s existing pulp mill operations, secure the necessary grid connections for electricity and gas distribution, advance permitting processes and refine commercial agreements.
The partnership behind the project brings together complementary capabilities across the value chain. Södra operates the pulp mill that generates biogenic CO₂ as a by-product of its production processes. OX2 develops large-scale renewable energy projects in the region, whereas TES specializes in e-NG production technology and contributes technical know-how and market insight gained from scaling up similar projects globally.
e-NG is a “fossil-free” chemically equivalent to fossil natural gas; from this vantage point, it serves as a drop-in fuel that can be used immediately in existing infrastructure without any modifications. Potential applications include maritime fuel, chemical industry feedstock and industrial processes.
The project established a Heads of Agreement with an energy major for the purchase of the majority of the planned production volume. Subject to the findings and subsequent investment decision by the partners, the facility should enter operation in the early 2030s, on time for the entry into force of sizeable EU RED III RFNBO obligations. Decisions on progressing to subsequent stages will be taken jointly by the partners based on the results of this phase.
