Methanol as a marine fuel proposed in Athens seminar

The seminar, held in late May, was organised by the consultancy Sea Commerce with support from the Methanol Institute, Methanex and FEDCOM. It brought together more than 70 delegates to hear from stakeholders advocating the use of methanol as a marine fuel, including Waterfront Shipping Co., Marinvest Shipping, The Methanol Institute and MAN Energy Solutions.

The speakers discussed the use of methanol as fuel from the point of view of ship design and construction, management and operations, propulsion and regulatory issues, drawing on direct experience and expert insight.

Seminar series organiser Capt. Saleem Alavi, President of Sea Commerce, argued methanol’s advantages when compared to LNG, which is being marketed as a long term solution.

“Methanol is similar to existing liquid marine fuels and is much easier to handle than LNG, as existing fuel tanks can be used, while the cost of conversion to methanol is 25% of an LNG conversion. Beyond cost savings, methanol is the only 2020-compliant fuel capable of intrinsically achieving NO_X Tier III compliance by use of water in fuel technology. In the near term, bio-methanol has near zero CO₂ footprint, hence it is capable of addressing the forthcoming IMO CO₂ reduction regulations.”

Paul Hexter, President of Waterfront Shipping, a wholly owned subsidiary of Methanex, explained that methanol could be cost-competitive and delivered value beyond a simple bunker cost equivalent.

“On an energy equivalent basis, methanol is cost competitive over the cycle compared to conventional low sulfur fuels such as MGO. Going forward, we see significant value creation opportunities of a methanol flex fuel engine, with efficiency gains mitigating expected increases in the price of conventional ultra-low sulfur fuels and the potential to eliminate selective catalytic reduction. These benefits make methanol a viable clean fuel option for the marine industry and part of the solution to help meet future emissions regulations.” Peter Hinchliffe, Consultant to the Methanol Institute provided a perspective on the development of regulations governing the use of methanol, in the revision of the IGF Code by IMO.

“We are in a confidence-building stage at the moment where we can see a clear trajectory through sulfur regulations to the IMO strategy on GHG reduction and shipowners need to see this as a continuum; a knee jerk reaction to first sulfur and then to CO₂ reduction will not be cost-effective. Methanol provides a solution that addresses both regulations and over time should be both a cost-effective and long term solution.”

Fredrik Stubner, Director Ship Management Marinvest Shipping, shared real life operational experience running tankers powered by methanol on behalf of Waterfront Shipping.

“Our first four ships delivered in 2016, have not experienced any serious issues that have resulted in off-hire or idle time and we now have in excess of 45 000 successful running hours on methanol. What should be realised is that the EEDI reduction introduced in 2030 will apply for new ships as well as old. We expect that carbon emissions will be measured from well to wake, so methanol which can be produced from many different sources will have big advantages.”

George Drossos, Head of Marine New Sales, MAN Energy Solutions Hellas stressed the simplicity of adopting methanol fuelled engines as well as the fuel’s ability to meet NO_X emissions regulations.

“Our LGIM methanol engine not only lowers SO_X and CO₂ emissions, our latest tests show that mixed with water, methanol can meet Tier III NO_X emissions without any additional SCR equipment. Installation is simple as a methanol fuel gas supply system operates at low-pressure and fuel is stored without the need for cryogenics. Engines can be retrofitted easily with very few components, thereby increasing the value of the vessel.”

The seminar was live streamed and sponsored by the Society of Naval Architects and Marine Engineers (SNAME) which will make a recording available via its website.

Feedback from delegates suggested that the industry still requires additional data and practical information on the use of methanol as marine fuel and on its potential as a sustainable fuel when produced from renewable sources. Basil Galanomatis, Manager, Newbuilding Contracting, George Moundreas & Company SA said:

“Methanol seems to be one of the most attractive solutions for use as marine fuel provided the issues of availability and production cost are resolved. The method of methanol production by capturing atmospheric CO₂ seems to be very promising in respect to a dramatic reduction in GHG emissions.”

The next seminar in the series will be held in Sao Paolo, Brazil in August (date to be finalised).
