Rolls-Royce Successfully Tests First Pure Methanol Marine Engine – Milestone For More Climate-Friendly Propulsion Solutions
The title of this post, is the same as that of this press release from Rolls-Royce.
These four bullet points act as sub-headings.
- World first: first high-speed 100 percent methanol engine for ships successfully tested
- Cooperation: Rolls-Royce, Woodward L’Orange and WTZ Roßlau are developing sustainable propulsion technology in the meOHmare research project
- Green methanol: CO2-neutral, clean and safe marine fuel
- Dual-fuel engines as a bridging technology on the road to climate neutrality
Rolls-Royce has successfully tested the world’s first high-speed marine engine powered exclusively by methanol on its test bench in Friedrichshafen. Together with their partners in the meOHmare research project, Rolls-Royce engineers have thus reached an important milestone on the road to climate-neutral and environmentally friendly propulsion solutions for shipping.
“This is a genuine world first,” said Dr. Jörg Stratmann, CEO of Rolls-Royce Power Systems AG. “To date, there is no other high-speed engine in this performance class that runs purely on methanol. We are investing specifically in future technologies in order to open up efficient ways for our customers to reduce CO2 emissions and further expand our leading role in sustainable propulsion systems.”
Rolls-Royce’s goal is to offer customers efficient ways to reduce their CO2 emissions, in-line with the ‘lower carbon’ strategic pillar of its multi-year transformation programme. The project also aligns with the strategic initiative in Power Systems to grow its marine business.
These are some questions.
Why Methanol?
Rolls-Royce answer this question in the press release.
Green methanol is considered one of the most promising alternative fuels for shipping. If it is produced using electricity from renewable energies in a power-to-X process, its operation is CO2-neutral. Compared to other sustainable fuels, methanol is easy to store, biodegradable, and causes significantly fewer pollutants.
“For us, methanol is the fuel of the future in shipping – clean, efficient, and climate-friendly. It burns with significantly lower emissions than fossil fuels and has a high energy density compared to other sustainable energy sources,” said Denise Kurtulus.
Note that Denise Kurtulus is Senior Vice President Global Marine at Rolls-Royce.
Could Methanol-Powered Engines Be Used In Railway Locomotives?
Given, there are hundreds of railway locomotives, that need to be decarbonised, could this be handled by a change of fuel to methanol?
I asked Google AI, the question in the title of this section and received the following answer.
Yes, methanol-powered engines can be used in railway locomotives, but they require a modification like high-pressure direct injection (HPDI) technology to be used in traditional compression ignition (CI) diesel engines. These modified engines typically use methanol as the primary fuel with a small amount of diesel injected to act as a pilot fuel for ignition, a process known as “pilot ignition”. Research and simulations have shown that this approach can achieve performance and thermal efficiencies close to those of standard diesel engines
From the bullet points of this article, it looks like Rolls-Royce have this pilot ignition route covered.
How Easy Is Methanol To Handle?
Google AI gave this answer to the question in the title of this section.
Methanol is not easy to handle safely because it is a highly flammable, toxic liquid that can be absorbed through the skin, inhaled, or ingested. It requires rigorous safety measures, proper personal protective equipment (PPE), and good ventilation to mitigate risks like fire, explosion, and severe health consequences, including blindness or death.
It sounds that it can be a bit tricky, but then I believe with the right training much more dangerous chemicals than methanol can be safety handled.
How Easy Is Green Methanol To Produce?
Google AI gave this answer to the question in the title of this section.
Producing green methanol is not easy; it is currently more expensive and capital-intensive than traditional methods due to high production costs, feedstock constraints, and the need for specialized infrastructure. However, new technologies are making it more feasible, with methods that combine renewable energy with captured carbon dioxide and renewable hydrogen to synthesize methanol.
Production methods certainly appear to be getting better and greener.
Which Companies Produce Methanol In The UK?
Google AI gave this answer to the question in the title of this section.
While there are no major, existing methanol production companies in the UK, Proman is planning to build a green methanol plant in the Scottish Highlands, and other companies like Wood PLC and HyOrc are involved in the engineering and construction of methanol production facilities in the UK. Several UK-based companies also act as distributors or suppliers for products, such as Brenntag, Sunoco (via the Anglo American Oil Company), and JennyChem.
It does appear, that we have the capability to build methanol plants and supply the fuel.
How Is Green Methanol Produced?
Google AI gave this answer to the question in the title of this section.
Green methanol is produced by combining carbon dioxide and hydrogen under heat and pressure, where the hydrogen is created using renewable electricity and the carbon dioxide is captured from sustainable sources like biomass or industrial emissions. Two main pathways exist e-methanol uses green hydrogen and captured carbon dioxide, while biomethanol is made from the gasification of biomass and other organic waste.
Note.
- We are extremely good at producing renewable electricity in the UK.
- In Rolls-Royce To Be A Partner In Zero-Carbon Gas-Fired Power Station In Rhodesia, I discuss how carbon dioxide is captured from a power station in Rhodesia, which is a suburb of Worksop.
In the Rhodesia application, we have a Rolls-Royce mtu engine running with carbon-capture in a zero-carbon manner, producing electricity and food-grade carbon-dioxide, some of which could be used to make methanol to power the Rolls-Royce mtu engines in a marine application.
I am absolutely sure, that if we need green methanol to power ships, railway locomotives and other machines currently powered by large diesel engines, we will find the methods to make it.
What Are The Green Alternatives To Methanol For Ships?
This press release from Centrica is entitled Investment in Grain LNG, and it gives hints as to their plans for the future.
This heading is labelled as one of the key highlights.
Opportunities for efficiencies to create additional near-term value, and future development options including a combined heat and power plant, bunkering, hydrogen and ammonia.
Bunkering is defined in the first three paragraphs of its Wikipedia entry like this.
Bunkering is the supplying of fuel for use by ships (such fuel is referred to as bunker), including the logistics of loading and distributing the fuel among available shipboard tanks. A person dealing in trade of bunker (fuel) is called a bunker trader.
The term bunkering originated in the days of steamships, when coal was stored in bunkers. Nowadays, the term bunker is generally applied to the petroleum products stored in tanks, and bunkering to the practice and business of refueling ships. Bunkering operations take place at seaports and include the storage and provision of the bunker (ship fuels) to vessels.
The Port of Singapore is currently the largest bunkering port in the world. In 2023, Singapore recorded bunker fuel sales volume totaling 51,824,000 tonnes, setting a new industry standard.
Note.
- After Rolls-Royce’s press release, I suspect that methanol should be added to hydrogen and ammonia.
- I don’t think Centrica will be bothered to supply another zero-carbon fuel.
- I can see the Isle of Grain providing a lot of fuel to ships as they pass into London and through the English Channel.
- Centrica have backed HiiROC technology, that makes hydrogen efficiently.
I can see the four fuels ammonia, hydrogen, LNG and methanol competing with each other.
What Are The Green Alternatives To Methanol For Railway Locomotives?
The same fuels will be competing in the market and also Hydrotreated Vegetable Oil (HVO) will be used.
