Excessive-speed methanol engine for transport now efficiently examined, says Rolls-Royce

The world’s first high-speed marine engine operating completely on methanol has been efficiently examined, Rolls-Royce introduced on 27 October, in what appears an vital milestone for carbon-neutral transport.

Whereas methanol engines in transport have up to now been demonstrated with the bigger, slower-speed class of vessels, Rolls-Royce’s announcement marks a technological first within the growth of a high-speed marine engine (i.e., one appropriate for smaller vessels reminiscent of ferries and yachts).

In a video, Dr Johannes Kech, Head of Methanol Engine Growth within the Energy Techniques division at Rolls-Royce, defined among the technical hurdles that needed to be overcome, together with the whole absence of lubricity with methanol – in different phrases, it has no lubricating properties, in contrast to diesel – which required the group to work with suppliers to develop a brand new injection system.

There are additionally vital variations within the combustion properties of methanol in comparison with diesel, together with its a lot greater ignition temperature, and the truth that it burns far more shortly. “Now we have basically redesigned the combustion course of, the turbocharging, and the engine management system – and even tailored our take a look at bench infrastructure,” he mentioned, in a press launch from the group. “Preliminary checks present that the engine is operating easily – now it’s time for fine-tuning.”

Accomplished on the firm’s take a look at bench in Friedrichshafen, southern Germany, the innovation is a product of the meOHmare analysis venture, which goals to develop a CO₂-neutral high-speed marine engine powered by inexperienced methanol by the top of 2025.

Rolls-Royce, injection system specialist Woodward L’Orange, and the WTZ Roßlau expertise and analysis centre have been engaged on the meOHmare joint venture, which is funded by the German Federal Ministry for Financial Affairs and Power.

“It is a real world first,” mentioned Dr. Jörg Stratmann, CEO of Rolls-Royce Energy Techniques AG. “Thus far, there isn’t a different high-speed engine on this efficiency class that runs purely on methanol. We’re investing particularly in future applied sciences to be able to open up environment friendly methods for our clients to cut back CO2 emissions and additional broaden our main function in sustainable propulsion techniques.”

An vital sign
“With this profitable take a look at run, we’re sending a transparent sign: inexperienced methanol is a future-oriented gasoline – and the expertise for it’s right here,” mentioned Denise Kurtulus, Senior Vice President World Marine at Rolls-Royce. “The one-fuel methanol engine is a sexy answer, particularly for operators of ferries, yachts or provide vessels who wish to scale back their carbon footprint. The duty now could be to create the framework situations for wider use.”

Alongside the single-fuel methanol engine, Rolls-Royce can also be creating a dual-fuel idea that may function on each methanol and diesel — serving as a bridging expertise till inexperienced methanol turns into extra broadly accessible.

Why methanol?
Inexperienced methanol is seen as one of the promising various fuels for the maritime business. When produced utilizing renewable electrical energy in a power-to-X course of, it gives CO₂-neutral operation, is biodegradable, and emits considerably fewer pollution than fossil fuels.

It additionally has benefits in being liquid and straightforward to retailer. In comparison with hydrogen, it doesn’t require pressurised tanks or different types of specialised dealing with.

“For us, methanol is the gasoline of the long run in transport – clear, environment friendly, and climate-friendly,” mentioned Kurtulus. “It burns with considerably decrease emissions than fossil fuels and has a excessive power density in comparison with different sustainable power sources.”
