ELIRE Maritime and consortium partners on Monday (25 May) announced the successful completion of the UKRI-funded Clean Maritime Demonstrator Competition Round 6 (CMDC6) programme.

CMDC6 is a GBP 1 million (USD 1.3 million) feasibility programme and initiative delivered by Innovate UK in partnership with the UK Shipping Office for Reducing Emissions (UK SHORE), part of the UK Department for Transport.

The partners are Ricardo UK, Schneider Electric, Rux Energy UK, Triton Anchor Europe, OREC (Offshore Renewable Energy Catapult), and the University of Strathclyde. 

The programme successfully validated one of the world’s first fully grid-independent Hydrogen Floating Power Hub systems capable of delivering clean power directly to vessels at berth without requiring traditional shore-side grid infrastructure. 

The consortium demonstrated that large vessels can realistically be powered at berth today using existing hydrogen, battery, fuel cell, and electrical technologies integrated into a modular floating maritime system designed for rapid deployment across global ports.

The solution can now be deployed and would be expected to support the reduction of up to 500,000 tonnes of CO₂ emissions globally over the next decade through a scalable maritime clean energy infrastructure capable of operating independently from constrained port grids.

“Ports are under increasing pressure to decarbonise while facing major infrastructure constraints,” said Luke Jenkinson, Founder and CEO of ELIRE Maritime. 

“The Hydrogen Power Hub proves that ports do not need to wait years for grid upgrades to begin reducing emissions. We have validated a practical, scalable, and deployable system capable of delivering clean power directly where it is needed most.”

The Hydrogen Power Hub establishes a new category of maritime infrastructure by moving energy and power generation as well as storage onto water rather than relying on fixed, land-based systems constrained by grid access, cost, permitting, and land availability.

At full configuration, this particular validated system is capable of delivering 5MW of continuous clean power output directly to vessels at berth, enough to support medium-sized cruise vessels and other large maritime assets requiring both 6.6kV and 11kV shore power connections. This system integrates three modular hexagonal floating platforms with a combined 1,200 sqm footprint, approximately 45MWh of battery energy storage capacity, modular fuel cell systems, hydrogen-powered generation, onboard renewable generation, and advanced grid-forming AC/DC electrical architecture.

The consortium confirmed the platform can deliver approximately 91MWh of energy per week while supporting repeated vessel charging operations without requiring major civil works, land reclamation, or expensive grid reinforcement.

The system uses approximately 7,500 to 8,000kg of hydrogen weekly, stored within modular ISO-compatible low-pressure storage containers integrated directly into the floating infrastructure. The current layout accommodates seven onboard hydrogen tanks, with refuelling operations expected approximately twice weekly, enabling ports to adopt hydrogen incrementally without requiring permanent hydrogen infrastructure during early deployment phases.

Instead of relying on oversized generators, the platform uses modular 1.3MW fuel cells operating continuously throughout the week to gradually charge the onboard batteries before rapidly dispatching energy when vessels arrive at berth.

Classification society DNV on Saturday (2 May) released technical and regulatory news on the highlights of IMO’s MSC 111 including approved interim guidelines for ships using hydrogen and ammonia cargo as marine fuels as well as endorsed work plans to address regulatory safety barriers to alternative fuels and new technologies.

The following are excerpts of the article: 

The 111th session of the Maritime Safety Committee (MSC 111) was held from 13 to 22 May 2026. The adoption of a new goal-based Code for Maritime Autonomous Surface Ships (MASS) marks a key milestone in the IMO’s work to ensure that the regulatory framework keeps pace with the rapid development of shipping technologies. MSC 111 also approved revised Explanatory Notes for the Safe Return to Port concept for passenger ships, as well as draft amendments to the IGC Code for gas carriers to incorporate a decade of Unified Interpretations, turning operational experience into clearer and more consistent requirements.   

Training for seafarers on alternative fuels and new technologies

MSC 111 approved new “Interim guidelines on training for seafarers on ships using methyl/ethyl alcohol as fuel”, as well as new “Interim guidelines on training for seafarers on ships using amm onia as fuel”.

The fuel-specific guidelines support the generic “Interim guidelines on training for seafarers on ships using alternative fuels and new technologies to support the reduction of GHG emissions from international shipping” (STCW. 7/Circ.25),which were approved by MSC 110 in 2025.

MSC 111 further endorsed the work plan for the further development of training provisions for seafarers on ships using alternative fuels and new technologies.

Ships using hydrogen as fuel 

MSC 111 approved “Interim using hydrogen as fuel” guidelines for the safety of ships

Ships using ammonia cargo as fuel

MSC 111 approved “Interim guidelines for use of ammonia cargo as fuel on gas carriers”. These guidelines aim to support the safe handling of ammonia as fuel, with main focus on areas outside the cargo areas to ensure safety for the crew and ship.

IGC Code – ships carrying gases or low flashpoint fuels 

MSC 111 approved draft amendments to the IGC Code to incorporate the large number of Unified Interpretations (UIs) developed since the latest major review of the code, which entered into force in 2016. The primary objective of the draft amendments is to remove ambiguity and promote the consistent implementation of the IGC Code requirements.

The draft amendments to the IGC Code are expected to enter into force on 1 July 2028, subject to adoption by MSC 112 (December 2026).

The draft amendments to the IGC Code will apply to ships constructed on or after 1 July 2028, i.e. ships:

for which the building contract is placed on or after 1 July 2028; or in the absence of a building contract, the keels of which are laid or which are at a similar stage of construction on or after 1 January 2029; or the delivery of which is on or after 1 July 2032.

Draft amendments to the model form of the International Certificate of Fitness for the Carriage of Liquefied Gases in Bulk in Appendix 2 of the IGC Code were approved to reflect the three-date application provision.

The following MSC Circulars, containing UIs to the IGC Code, are expected to be suspended upon adoption and entry into force of the IGC Code amendments:

• MSC.1/Circ.1543, MSC.1/Circ.1559, MSC.1/Circ.1590,
• MSC.1/Circ.1606, MSC.1/Circ.1617, MSC.1/Circ.1625,
• MSC.1/Circ.1651, MSC.1/Circ.1669 and MSC.1/Circ.1679.

Classification society DNV on Wednesday (20 May) said it has released a new recommended practice (RP) for hydrogen as ship fuel, outlining the competence requirements for crew, inspectors, and technical personnel to support the proper handling of hydrogen systems on board ships.

Hydrogen is gaining traction as a marine fuel, with seven vessels currently in operation and another 30 in the orderbook. However, several safety barriers like hydrogen leakage, low ignition energy, and management of high‑pressure or cryogenic storage, still limit its uptake. But with proper training and a strong safety culture, and with ship designs engineered to limit risk as much as possible, its use can be managed more safely and efficiently.

The DNV-RP-0703 “Competence related to use of hydrogen as fuel” addresses hydrogen’s specific risk profile by defining structured competence requirements. The RP can also be used as a basis for operational procedures and emergency preparedness planning. It builds on DNV’s existing competence framework for low‑GHG fuel, following RPs and Standards for LNG, ammonia, and methanol.

Cristina Saenz de Santa Maria, CEO Maritime at DNV, said: “Hydrogen represents one of several possible pathways in maritime decarbonization. The development of efficient safety regulations and guidelines is fundamental for hydrogen to evolve from large-scale demonstration to commercial use. 

“To get there it is essential that the industry develops competence levels among seafarers in parallel with technical solutions so that they can operate hydrogen‑fuelled vessels with confidence.”

DNV’s RP is designed to supplement existing regulatory frameworks such as the STCW Convention and ISM Code by providing hydrogen‑specific competence guidance for organizations considering using hydrogen as a marine fuel. 

It is also intended for use by shipowners and operators for onboard familiarization and competence management, by maritime academies and training institutions to develop curricula and courses, and by third parties as a reference for certification or verification of learning programs and competence assessments.

Kirsten Birgitte Strømsnes, Business Development Leader in DNV, said: “The use of hydrogen as a ship fuel requires that crew and shore-based personnel are trained on its specific hazards, and that organizations reflect these risks in their management systems and competence frameworks. It also means ensuring safer ship designs and implementing the necessary technical barriers.

“We have developed this recommended practice using DNV’s established methodology for competence standards, with input from industry partners and with reference to international regulations. As industry experience with hydrogen-fuelled vessels grows, this RP is intended to evolve in line with emerging best practices into a competence standard.” 

DNV has collaborated with industry partners Samskip, eCap Marine, Naval Dynamics, Chart Industries, LH2 Shipping, Torghatten, Shell, Everllence, and GreenH in developing the recommended practice.
