Solar To Hydrogen Efficiency Record Broken By Australian National University Researchers

The title of this post, is the same as that of this article on Hydrogen Fuel News.

The traditional route to produce green hydrogen from solar panels, is to create electricity and then use electrolysis to create the hydrogen.

This process goes direct and an improvement in efficiency of 17.6 %.

Rolls-Royce Commences Series Production Of Hybrid-Ready MTU PowerPacks For Irish Rail

The title of this post, is the same as that of this article on CleanTechnica.

This is the introductory paragraph.

Rolls-Royce is to supply its very first series production MTU PowerPacks which are prepared for future use as hybrid traction units: Iarnród Éireann Irish Rail, the national railway operator of the Republic of Ireland, has ordered 41 of these MTU Hybrid-ready PowerPacks. Fitted with MTU 6H 1800 R86 engines, the PowerPacks comply with the EU Stage V emissions directives and each delivers 375 kW from the diesel engine as well as 150 kW from the electrical machine.

Later the aim would be to add batteries to the PowerPacks to make the trains fully hybrid.

I do think Rolls-Royce MTU might have a game-changer here.

  • You take a modern fleet of diesel multiple units like a British Class 170 trains or an Irish Class 22000 trains,
  • For starters you replace the old diesel engine, with a modern one that meets all the latest environmental regulations.
  • It surely helps both sales and engineering, when the old diesel engine was supplied by MTU.
  • Later you fit appropriately sized batteries to the PowerPack to create full hybrids with regenerative braking.

In Iarnród Éireann Orders Stage V MTU PowerPacks, I said this about fuel consumption and emissions.

The aim is to achieve a reduction of over thirty percent in both fuel consumption and carbon dioxide emissions.

I would suspect that with savings like that, the case for conversion might be an easy sell.

Hitachi Rail To Acquire Perpetuum In Digital Expansion

The title of this post, is the same as that of this article on Railway Gazette.

This is the first two paragraphs.

Hitachi Rail Ltd has agreed to acquire Southampton-based condition monitoring specialist Perpetuum as part of a strategy to strengthen the use of digital technology in rail operations.

Established as a university spin-off less than a decade ago, Perpetuum developed the use of bogie-mounted self-powered vibration sensors to monitor the condition of rolling stock. Wireless equipment fitted to around 3 000 vehicles operating across three continents sends back real-time data about the performance of wheelsets, gearboxes, motors and bogies.

It seems to me, that Hitachi have bought an interesting company.

Let’s hope they develop the technology, but keep that development in Southampton.

Do We Need More New Measurement Trains?

In New Measurement Train – 30th July 2020, I said this.

With all the spare InterCity 125 trains at present, will Network Rail create a second train?

We have now had the tragic Stonehaven Derailment, where three have been sadly killed.

Increasingly, we seem to be getting weather-related problems on the UK’s railways.

I can remember several in the last few years.

So perhaps just as the Hatfield Crash led to the New Measurement Train, we should up our testing and the development of new tests.

Extra trains would increase the amount of testing, but also provide more laboratory space to test the testing systems in real railway conditions.

Perhaps, if a University or high-tech company has a feasible idea, there should be a mechanism, whereby they can rent space in the trains, just as they can on satellite launchers.
