The Zero Emissions Ship Technology Association (ZESTAs) on Tuesday (3 February) welcomed Hydro Air Concept Energie (HACE), reinforcing the deployment of Absolute Zero emissions shipping ecosystems.

HACE’s non-intermittent wave energy system, designed to operate across a wide wave spectrum, delivers electricity with typical load factors in the 50 to 90% range, depending on site, and with very low lifecycle greenhouse gas emissions, measured at only a few grams CO₂e per kWh. 

The technology is modular and scalable, from megawatt-scale installations to multi-hundred-megawatt or gigawatt-class arrays, and is designed for integration with coastal and port infrastructure, with no adverse impact on marine ecosystems, while contributing to coastal protection through wave attenuation.

Energy supply is a foundational constraint. Zero-emissions vessels, shore power, and maritime fuel production all depend on access to continuous, genuinely zero-emissions electricity and hydrogen. Intermittent energy sources, while valuable in many contexts, pose specific challenges for port operations and for electrolysers used in maritime hydrogen production. 

Dr Jean-Luc Stanek, President of HACE, said: “Shipping’s transition to zero emissions requires energy systems that are reliable, scalable, and compatible with the operational realities of ports and coastal infrastructure. ZESTAs brings together the actors needed to address these issues in an integrated way, and we see strong alignment between our work and this approach.”

For ZESTAs, HACE strengthens the energy dimension of its work, particularly in coastal and port environments where space constraints, resilience, and environmental integrity are decisive.

Madadh MacLaine, Secretary General of ZESTAs, said: “Maritime shipping’s ability to meet the IMO’s revised GHG strategy targets hinges on access to continuous, zero-emissions energy. The HACE system goes well beyond this by also providing freshwater  and preventing coastal erosion. 

“ZESTAs is thrilled to partner with visionaries confronting the challenges of climate change mitigation and adaptation through a single technology. We look forward to including the HACE solution as a component of the Absolute Zero emissions ecosystem.”

For ZESTAs, this transition is inseparable from ocean health. Eliminating emissions from shipping is not an abstract climate objective, but a necessary condition for protecting marine ecosystems already under threat  from heating , acidification, underwater noise, and coastal degradation. Absolute Zero emissions shipping is therefore not only an industrial challenge, but a prerequisite for a sustainable relationship between maritime activity and the ocean.

ZESTAs brings together technology developers, ship designers, operators, ports, energy providers, and regulators to enable the integration of mature zero-emissions technologies into deployment-ready ecosystems. Today, ZESTAs brings together over 50 members, collectively covering the full range of components required to operate Absolute Zero emissions vessels — on board ships, in ports, and across associated energy supply chains.

MacLaine added, “systemic change in shipping comes not from isolated pilots, but from deploying integrated ecosystems where technology, infrastructure, regulation, finance, and operations are developed together.”

By joining ZESTAs, HACE will contribute to the association’s technical, regulatory, and deployment-focused activities, supporting the development of integrated maritime systems in which vessels, ports, and energy supply are treated as a single operational whole.

The Intersessional Working Group on Reduction of Greenhouse Gas (GHG) Emissions from Ships (ISWG-GHG 22) met for its 22nd meeting from 1 to 4 September 2026, chaired by Mr. Sveinung Oftedal (Norway), according to the International Maritime Organization on Friday (4 September). 

According to a meeting summary by IMO, the meeting had a high level of participation, with nearly 1200 registered participants, in person and online.

During the meeting participants considered the following agenda items:

Consideration of proposals, including documents submitted to MEPC 84 and 85, previous sessions of ISWG-GHG, as well as documents submitted to ISWG-GHG 22, on how to address concerns with the draft amendments to MARPOL Annex VI on the Net-Zero Framework, in line with the 2023 IMO GHG Strategy

Following constructive discussions, the Chair expressed his observation of a genuine willingness within the Group to make concrete further progress at the next ISWG-GHG meeting and work towards presenting text to MEPC 85 that adequately addresses the noted progress made in the consideration of proposals on how to address concerns raised regarding the draft amendments to MARPOL Annex VI on the mid-term measure.

The Group invited interested delegations to continue to consult intersessionally to address remaining concerns with the draft amendments to MARPOL Annex VI, in line with the 2023 IMO GHG Strategy, taking into account views expressed at the Group’s session, with a view to submitting concrete proposals reflecting enhanced convergence allowing timely adoption and effective implementation.

Further consideration of the draft guidelines supporting the uniform and effective implementation of IMO’s mid-term measures.

The Group held a preliminary exchange of views on this agenda item, although time became a limiting factor and the Group and agreed to defer the consideration of all documents submitted to this session under this agenda item to ISWG-GHG 23 (23-27 November 2026).

Further consideration of the development of the IMO Life Cycle GHG Assessment (LCA) framework.

Due to time constraints, the Group was not able to consider the agenda item related to the IMO Life Cycle GHG Assessment (LCA) framework. The Group deferred the consideration of those documents to ISWG-GHG 23, in conjunction with the report of the fourth meeting of the GESAMP-LCA Working Group expected to be submitted to MEPC 85.

Next steps

The next meeting of the Intersessional Working Group on Reduction of Greenhouse Gas (GHG) Emissions from Ships (ISWG-GHG 23) is scheduled for 23 to 27 November 2026, ahead of MEPC 85 (30 November to 3 December).

The second extraordinary session of MEPC (adjourned last October) is scheduled to resume on 4 December, subject to discussions at MEPC 85.

UCL on ISWG-GHG 22: Majority back GHG pricing, centralised fund in IMO NZF talks

A significant majority of IMO member states backed a centralised system for collecting revenues to reward early adopters and support a just transition, according to UCL.

UCL Shipping and Oceans Research Group on Friday (4 September) said the IMO’s 22nd Intersessional Working Group on GHG emissions has concluded with significant majority of member states supporting a centralised system for collecting revenues, operationalised through a GHG price (RU price), and disbursing it for rewards for early adopters and supporting a just and equitable transition. 

The group of member states focused on a technical-only solution and abandonment of GHG pricing, remained small and consistently composed of strongly fossil fuel aligned governments.

Just as at MEPC 84, the political dynamics observed at MEPC.ES2 did not occur in this meeting. 

The discussions were more representative of the ISWG-GHG 19 and MEPC 83 negotiating dynamics, but this does not rule out the potential for the dynamics that occurred at MEPC.ES2 returning in future meetings. That said, there was reassuring evidence from the week that reduces that risk, including in the contrast between strong public (press) positions taken against the IMO’s NZF, and the substance of how delegations negotiated in the meeting.

Dr Tristan Smith, Professor of Energy and Transport at UCL Shipping and Oceans Research Group, said: “Whilst there are many positives to take away – there is clear potential for a return to a strong policy solution and decision making this December, there remains high uncertainty in the extent that both industry’s transition and low-income countries’ transitions will be supported. 

“There remains high risk that in the effort to find a creative way forwards, the equilibrium between these two aspects, that enabled the NZF in the first place, is lost to the detriment of the outcome overall.”

In addition to the discussion on centralised system for revenue collection and disbursement, the meeting discussed a number of other items as guided by the chair, discussed in detail with member state positions in the readout. Some of these included:

  • GFI (Global Fuel Intensity) reduction pathway: GFI is likely to be softened initially (around 2030), but then steeper in the period to 2040. 
  • ZNZ rewards: ZNZ reward still broadly supported and a priority to many member states, but the broad support for a multiplier, despite it being taken off the table at the last meeting, could yet lead this to be incorporated to provide incentivisation. 
  • Compliance approaches
  • Most interventions confirmed support for the compliance mechanisms as setup in NZF ‘as is’. The strongest support was for the two least controversial options common to all proposals: reducing GHG intensity and pooling/transfer of SU. 
  • Direct contributions: Japan’s proposal to replace GHG pricing with shipowner-directed contributions was robustly rejected, particularly by the member states that would need to ‘swing’ to support it for this to start to build momentum. 
  • SU (Surplus Units) trading: Majority of member states opposed the inclusion of energy efficiency SU credits and the concept of printing SU’s to manage an SU price shock, citing various reasons, primarily a concern that this would destabilise the SU market and undermine investment predictability. 
  • Netting: China’s proposal to balance of RU and reward payments that could be netted to form a single transaction received broad support. However, the details of the concept will now need to be set out in guidelines and there remain a number of issues regarding this approach, as raised by several delegations.
