Uniper has moved its proposed NorthStarH2 e-methanol facility in Östersund into basic engineering, awarding contracts worth more than SEK100 million to define the plant before a planned 2028 investment decision.
Uniper has appointed AFRY, Carbon Clean, Siemens Energy, and Topsoe to work across electrolysis, carbon capture, methanol synthesis, and purification. The front-end engineering and design phase is expected to run for approximately one year.
The proposed plant is designed to produce around 115,000 tonnes of e-methanol annually from renewable electricity and biogenic carbon dioxide. Uniper intends to submit an environmental permit application during autumn 2026, with commissioning currently scheduled to begin in 2031 if the project secures permits, customers, financing, and final investment approval.
Moving into FEED represents a material project-stage change because NorthStarH2 remains a development proposal rather than a sanctioned production plant. Early studies can establish a process route and nominal output, but basic engineering has to convert those assumptions into equipment sizes, energy balances, plot requirements, interfaces, capital estimates, and a construction basis sufficiently detailed for investment decisions.
The process starts with electrolysis, using renewable electricity and water to produce hydrogen. That hydrogen is combined with captured biogenic carbon dioxide before methanol synthesis and purification produce the final liquid fuel.
Each stage has to be sized around the others. An electrolysis plant producing more hydrogen than the synthesis section can accept leaves expensive equipment underused, while interruptions to carbon supply can restrict output even when electricity and electrolyser capacity remain available. Storage and operating flexibility therefore become part of the process design.
Uniper has previously identified regional energy company Jämtkraft as the intended source of biogenic carbon dioxide from its bioenergy operation in Östersund. Locating carbon supply, renewable electricity, water, and transport infrastructure within the same area reduces some logistical constraints, although it does not remove the cost of conditioning, capturing, moving, and storing the feed streams.
Electricity will remain central to plant economics because electrolysis is energy intensive. Compression, gas handling, methanol synthesis, purification, pumping, and utilities add further electrical and thermal demand, meaning the price and availability of renewable power will influence both production cost and plant utilisation.
The FEED contractors will therefore have to optimise more than individual equipment packages. Waste heat from one process section may be recoverable elsewhere, while the output and operating profile of electrolysers, carbon capture, synthesis, and purification have to be coordinated through process control and intermediate storage.
Plant availability will also affect cost per tonne. Equipment designed around high annual utilisation becomes expensive if upstream feedstock shortages, maintenance, power constraints, or downstream outages repeatedly reduce production. Engineering redundancy has to be balanced against the cost of duplicating high-value process equipment.
NorthStarH2 is intended to supply markets including transport and the chemical industry. Methanol is already handled globally as a liquid chemical and fuel, giving e-methanol an established physical product format even though its production economics differ materially from conventional fossil-derived methanol.
Shipping is one potential market because suitably configured vessels can use methanol without the cryogenic storage requirements associated with some alternative fuels. Fuel systems, tanks, safety arrangements, and bunkering infrastructure still have to be designed around methanol’s characteristics, and the emissions benefit depends on how the hydrogen and carbon inputs are produced.
The chemical sector offers another route because methanol is already used as an industrial feedstock. Substitution can therefore reduce fossil-derived carbon inputs without requiring an entirely new downstream molecule, although customers still have to accept the price, certification, and supply conditions attached to lower-carbon production.
That makes long-term offtake important before construction. A technically workable plant is not automatically financeable where production costs are higher than conventional alternatives and revenue depends on customers placing value on lower lifecycle emissions.
Uniper plans to reach a final investment decision in 2028. The interval gives the company and its contractors time to develop the plant design, complete permitting work, improve capital-cost estimates, negotiate commercial arrangements, and establish whether the expected e-methanol price can support financing.
The more than SEK100 million now committed to engineering moves NorthStarH2 beyond early concept work but stops well short of construction approval. Over the next year, the project has to establish what the proposed 115,000-tonne plant will actually require in equipment, energy, land, utilities, and capital — the information that will determine whether the 2031 commissioning target remains credible.
