EU Shipping E-Fuel Support Proposal Faces Calls for Stronger Investment Guarantees

Summary

Transport & Environment has called for changes to the EU’s proposed shipping support mechanism to help renewable fuel projects secure investment. An October 12 joint letter recommends reserving allowances for e-fuels and allowing support to be booked in advance, arguing that price incentives alone may not generate long-term purchasing commitments.

Letter seeks stronger support for e-fuel investment

EU shipping e-fuel support should provide greater certainty for producers and buyers, according to recommendations published by Transport & Environment.

The joint letter addresses the proposed Sustainable Maritime Alternative Propulsion mechanism, known as SMAP, within negotiations on reforming the EU Emissions Trading System.

It identifies potential support estimated at €15 billion between 2028 and 2040, while arguing that the mechanism needs a stronger connection to long-term fuel purchasing.

The recommendations remain advocacy proposals. They do not establish new obligations or an operational funding entitlement.

Two changes target the financing gap

The letter proposes earmarking a substantial share of SMAP allowances for e-fuels.

It also recommends a “book-in-advance” arrangement through which shipping companies could obtain greater confidence about future support before committing to fuel purchases.

The underlying argument is that capital-intensive production projects need dependable, long-term customers to secure financing. Without confidence in future price support, shipowners may hesitate to sign the contracts that producers require.

The signatories therefore want the mechanism to reward sustained e-fuel use and help projects progress towards final investment decisions.

That is a commercial financing argument alongside an environmental one: the design of support influences whether prospective demand becomes a contract that lenders can assess.

Commission proposal would reserve ETS allowances

The European Commission’s July 2026 ETS revision proposal envisages reserving 110 million allowances for shipping support through 2040, beginning in 2028 or the first year after the directive enters into force.

The proposed mechanism would help cover part of the price difference between conventional fossil fuels and eligible sustainable marine fuels.

It would also support eligible zero-emission propulsion technologies and equipment required to use qualifying fuels, subject to the proposed conditions.

This is broader than an e-fuel-only instrument. The latest recommendations seek to influence how support would be distributed within that wider scope.

The legislative proposal must be distinguished from an agreed programme. Its final design, eligibility rules and implementation arrangements remain subject to the EU legislative process.

Existing maritime carbon pricing provides the background

Shipping entered the EU ETS in January 2024.

The system places an allowance obligation on covered emissions, with a phased introduction: 40% of reported 2024 emissions, 70% of 2025 emissions and full coverage of emissions within the applicable scope from the 2026 reporting year.

The geographical rules generally cover all emissions from voyages between covered European ports and emissions within those ports, plus half the emissions from voyages connecting covered ports with destinations outside the system.

Methane and nitrous oxide enter maritime ETS coverage from 2026 alongside carbon dioxide.

These existing requirements create a cost for emissions. SMAP would add a proposed support channel intended to help shipping invest in alternatives.

FuelEU creates a separate demand signal

FuelEU Maritime complements carbon pricing by limiting the annual average greenhouse-gas intensity of energy used aboard covered ships.

Applicable from 2025, it begins with a 2% reduction against its reference level and becomes progressively more demanding, reaching 80% by 2050.

The framework assesses emissions across the fuel lifecycle, including carbon dioxide, methane and nitrous oxide.

For fuel producers, these requirements provide an indication of future demand for lower-emission energy. However, a regulatory requirement does not automatically settle which fuels customers will buy, at what price or under which contract duration.

That gap between future compliance demand and bankable purchasing commitments is central to the current debate.

Shipowners also seek greater revenue recycling

A separate October 15 intervention from the European shipowners’ association, ECSA, called for at least tripling the ETS revenues earmarked through SMAP.

Its position emphasises the scale of funding available for sustainable fuels and technologies, including energy-efficiency projects.

The two interventions address related questions: how much support shipping receives and how effectively that support enables investment. They also highlight choices over the balance between near-term improvements and emerging fuel production.

For shipowners, fuel developers and financiers, the outcome will influence contract negotiations and investment timing. The immediate issue is whether the final mechanism offers sufficiently predictable support to turn planned production into financed projects and sustained fuel supply.

FAQs

What is SMAP?

The proposed Sustainable Maritime Alternative Propulsion mechanism within the EU ETS reform.

What changes does the joint letter recommend?

Earmarking allowances for e-fuels and introducing a book-in-advance support mechanism.

Is SMAP already operational?

It remains part of a legislative proposal under negotiation.

Why do long-term fuel contracts matter?

They can give producers greater revenue certainty when seeking project finance.

How does FuelEU Maritime differ from the ETS?

FuelEU limits energy’s greenhouse-gas intensity; the ETS requires allowances for covered emissions.
