Rolls-Royce Successfully Tests mtu Engines With Pure Hydrogen

The title of this post, is the same as that of this press release from Rolls-Royce.

These are the two bullet points.

  • mtu gensets and cogeneration units to be further developed for 100% hydrogen use
  • First use in the new CO2-neutral container terminal in the German inland port of Duisburg

This is the first paragraph.

Rolls-Royce (LSE: RR., ADR: RYCEY) today announces that it has conducted successful tests of a 12-cylinder gas variant of the mtu Series 4000 L64 engine running on 100% hydrogen fuel. The tests, carried out by the Power Systems business unit, showed very good characteristics in terms of efficiency, performance, emissions and combustion. These tests mark another important step towards the commercial introduction of hydrogen solutions to meet the demand of customers for more sustainable energy.

Note.

  1. Rolls-Royce mtu have converted and tested a natural gas version of the Series 4000 L64 engine.
  2. The Class 43 power cars used in the iconic InterCity 125 train and powered by mtu V16 4000 R41R engines.

Are the two engines related? If so, can Rolls-Royce mtu build a hydrogen engine that could power an InterCity 125?

It was a rapid development.

Andrea Prospero, an engineer at Rolls-Royce responsible for the development of the hydrogen engine, is quoted as saying.

We are very pleased with the rapid progress. The very low engine emissions are well below the strict EU limits, no exhaust gas aftertreatment is required.

Due to the different combustion behaviour of hydrogen compared to natural gas, some engine components including fuel injection, turbocharging, piston design and control, were modified in the test engine. However, by using proven technologies within the Power Systems’ portfolio, such as mtu turbochargers, injection valves, and engine electronics and control, the development of the engine to use hydrogen was advanced quickly and efficiently.

Diesel and natural gas internal combustion engine manufacturers like Cummins, Rolls-Royce mtu and several other companies, have a long history of research, that they have the knowledge to convert diesel or natural gas engines to hydrogen.

So far only Cummins, JCB and Rolls-Royce mtu have disclosed a multi-fuel line of engines.

First Deployment For CO2-Neutral Power Supply At Duisport

There is a section in the press release called First Deployment For CO2-Neutral Power Supply At Duisport, where this is said.

Duisport, one of the world’s largest inland ports, is working with several partners to build a hydrogen-based supply network for its new terminal, ready for operation in 2024. In the future, most of the electricity required by the port itself will be generated directly on site from hydrogen in a CO2-neutral manner. This will be achieved by two combined heat and power plants with mtu Series 4000 hydrogen engines (with a total installed capacity of 2MW) as well as three mtu fuel cell systems (with a total installed capacity 1.5MW).

As part of its sustainability program, Rolls-Royce is realigning the product portfolio of Power Systems towards more sustainable fuels and new technologies that can further reduce greenhouse gas emissions.

There is also this Rolls-Royce graphic, which shows the energy sources.

It would appear batteries,  combined heap and power (CHP), grid electricity, hydrogen electrolyser, hydrogen storage and renewable electricity are being brought together to create a climate-neutral energy system.

Is this a world-first, where hydrogen engines and fuel cell systems will be working together?
