All pathways to truly sustainable fuels for the shipping and aviation sectors require green hydrogen, produced from renewables, with some of them requiring carbon dioxide from sustainable sources like direct air capture (DAC).

This was the main conclusion of a report released on Monday (11 September) by the SASHA Coalition, facilitated by Opportunity Green. 

The report revealed that there is a lack of policy supporting the production of green hydrogen, which is slowing down demand and discouraging investment, creating a “Green Hydrogen Gap”. 

It outlined how governments should prioritise the use of hydrogen and DAC in the aviation and shipping sectors because they lack decent alternatives, and also highlights the need for policy to ensure that these solutions can be rolled out at scale. 

While first-mover ambitious companies can step forward voluntarily to send clear, unambiguous and urgent demand signals to green hydrogen producers, their actions will always be in isolation without the backing of policymakers.  

The Green Hydrogen Gap report by Opportunity Green draws on exclusive research by Arup and looks at the policy landscape of green hydrogen and DAC in the UK and the EU. 

It found that hydrogen production is behind on projections of where it needs to be to meet the temperature goals of the Paris Agreement and that this is due to a lack of guaranteed demand across the board. 

The latest environmental policies from both the EU and the UK focus more on supporting biofuels and/or the use of gas (liquefied natural gas) in aviation and shipping respectively, rather than ensuring that green hydrogen – required for full decarbonisation – is prioritised for aviation and shipping.

Aoife O’Leary, CEO of Opportunity Green and Director of the SASHA Coalition, said: “There is a worrying delay in green hydrogen production, which means that if aviation and shipping don’t make their case clearly and loudly now, they won’t have access to fuels that will truly lead to sustainable decarbonisation.”

“Governments are already prioritising other industries for hydrogen, so without stronger policy, aviation and shipping will be overlooked.”

Kerosene and Heavy Fuel Oil currently meet the bulk of fuel demand for the marine and aviation industries, and it’s estimated that the total consumption of marine fuels account for around 5% of global oil demand.

Sally Prickett, Director of Hydrogen, CCUS and New Fuels in Arup’s Advisory team, said: “Clearly, shipping and aviation will be unable to decarbonise at the scale and pace required without alternative fuels. It’s unlikely that there will be a ‘one solution fits all’ fuel for these sectors, but one thing this research tells us is that green hydrogen will play a critical role in their decarbonisation as a feedstock for the majority of sustainable fuel pathways. Without green hydrogen, these sectors will struggle to find satisfactory zero emissions solutions.” 

According to the report, policy signals are supporting the uptake of hydrogen-derived fuels at both a UK and EU level. However, these are not on the scale that’s needed to meet Paris targets and are just one component that will drive the adoption of hydrogen-derived fuels. 

“Policymakers must recognise that green hydrogen will continue to be in limited supply in the coming decades and should therefore be targeted towards sectors – such as shipping and aviation – that have no more efficient routes to decarbonisation,” it said. 

Nuala Doyle, Policy Officer at the SASHA Coalition, said: “Both shipping and aviation have come under increasing scrutiny for their climate impact, resulting in additional regulation at international, regional and national levels. And regulation will only get stricter over time as the climate crisis worsens.”

“We know that the fuels that will fully decarbonise both sectors require green hydrogen and direct air capture. However, current regulations do little to incentivise these – instead the regulations encourage fuels that either are not scalable or are still fossil fuels. Without regulation that aligns with, and incentivises, the goal of zero emissions, companies may find they end up with stranded assets from investment in a fuel that is no longer acceptable to use.”

The UK Chamber of Shipping on Monday (3 August) published Alternative Fuels: Building the Safety Evidence Base, a report bringing together industry expertise to identify and assess the safety considerations associated with the fuels expected to power shipping’s transition to net zero.

Developed through the Chamber’s Safety of Alternative Fuels Working Group (SAFWG), the publication provides preliminary, high-level risk assessments covering five key fuel pathways: Battery Energy Storage Systems (BESS), biofuels, methanol, hydrogen and ammonia. 

Francesco Sandrelli, Policy Director (Environment) at the UK Chamber of Shipping, said: “Shipping is on a critical pathway to net zero. New fuels and energy sources are moving from pilot projects to commercial reality, but safety, standards and operational readiness must keep pace.

“There is no single fuel that will decarbonise shipping. Different vessel types, trades and operating environments will require different solutions. What is essential is that the transition takes place safely. This publication is an important step towards achieving that goal.”

Among the report’s key findings is the need for robust design and process safety frameworks to support the commercial deployment of alternative fuels. The research also highlights a number of cross-cutting themes, including material compatibility, emergency response preparedness, crew training and competence, and the need for clearer regulatory pathways. 

The report represents a major collaborative effort by industry to build a shared understanding of the opportunities and challenges associated with alternative marine fuels. It provides practical insights into the known risks, highlights where further work is needed, and creates a foundation for future research, regulation and operational learning. 

The SAFWG was established by the UK Chamber of Shipping to support industry understanding of the safety implications associated with emerging zero and near-zero emission fuels. 

The report is the culmination of the Working Group’s first year of activity, during which more than 200 participants from over 50 organisations collaborated through a series of technical workshops delivered by Policy Director Francesco Sandrelli, supported by Robert Merrylees and Paul Markides. 

The publication forms part of the UK Chamber’s wider work to support shipping’s transition to net zero while maintaining the highest standards of safety and operational excellence. 

Future work by the SAFWG will focus on identifying regulatory and knowledge gaps, developing project-specific case studies, expanding stakeholder engagement and establishing an incident and lessons-learned database.

The European Commission recently said it has approved a EUR 103 million (USD 119 million) State aid scheme by the Netherlands to accelerate the greening of the Dutch maritime fleet. 

The scheme will support the purchase of new clean and zero-emission vessels powered by renewable methanol or renewable hydrogen and the retrofitting of existing vessels to enable them to use renewable methanol and renewable hydrogen. 

It covers different types of vessels, including passenger, cargo and work vessels, mainly operating in the short-sea shipping segment. The support will take the form of direct grants awarded under an open, transparent and non-discriminatory selection process.

The scheme aims to help companies overcome high upfront investment costs and limited market incentives that currently slow the uptake of clean shipping technologies. The aid will be granted between 2027 and 2031 and will help bridge the investment gap in line with the objectives of EU legislation such as the FuelEU Maritime and the EU Emission Trading System.

The Commission assessed the measure under EU State aid rules, in particular Article 107(3)(c) of the Treaty on the Functioning of the EU and the 2022 Climate, Environmental Protection and Energy Aid Guidelines (CEEAG). 

“The Commission concluded that the scheme is necessary and appropriate as the supported investments would not take place without public support at the same scale and within the same timeframe. The measure is also proportionate as it has limited effects on competition and trade in the internal market,” it said.

Genevos and Koedood Marine Group team up on maritime hydrogen fuel cell deployment

Marine fuel cell systems provider Genevos recently said the company signed a Letter of Intent (LOI) with engine supplier Koedood Marine Group to explore the deployment of hydrogen fuel cell systems for inland and coastal maritime transport. 

The LOI was signed by Phil Sharp, co-founder and CTO of Genevos, and Mühlheim, Business Development Director of Koedood Marine Group during the 2026 Advanced Maritime Technology Show in Amsterdam.

Building on Koedood’s proven experience in hydrogen maritime projects – including its ongoing work with Mitsubishi Heavy Industries and TNO on hydrogen engine development – the collaboration will explore how ready-to-use marine fuel cell systems can support shipowners and shipyards in the transition towards zero-emission operations. 

“Koedood has a strong reputation in the maritime sector and a deep understanding of vessel operators’ needs. This LOI is an important step in exploring how Genevos’ hydrogen fuel cell systems can be deployed more widely across inland and maritime applications, helping shipowners reduce onboard emissions with robust, practical and scalable clean power solutions,” said Sharp.

The collaboration aligns with growing market demand for rapidly deployable hydrogen solutions and the wider need to accelerate the adoption of zero-emission technologies across the maritime sector. 

“With this collaboration, we are further strengthening our portfolio of maritime energy solutions. Together with Genevos, we are exploring how we can support our customers in the adoption of hydrogen technology,” said Mühlheim.
