Malta Energy Storage System Is Looking Forward To First Pilot

The title of this post is the same as that of this article on Tech Eplore.

This is the first paragraph.

Malta has received a round of funding and is graduated from “project” to group that can sail. The Cambridge, MA-based company is focused on the storage of electro-thermal energy and the funding put the group in celebration mode this month. In return, the company is turning up the volume on its potential role in the future of energy storage—namely, working out salt-based electro-thermal energy storage.

The article goes on to describe how the system works and I suggest you read it.

This is the last paragraph.

Malta CEO Ramya Swaminathan said the challenge ahead is about design and manufacturing, in Xconomy. Swaminathan said customers were expected to come from a variety of points in the energy system. Such as? She said they expect “developers with wind or solar projects who want firm power, to grid scale applications that can be in the hundreds of megawatts range, to critical backup for data centers, to isolated grid systems like island economies.”

I believe the technology has a lot going for it.

  • It has heavyweight financial backing.
  • The technology is very conventional and well-understood, which will ease manufacture and maintenance.
  • No complex or expensive raw materials are needed.
  • I would suspect that few, if any dangerous chemicals are needed.
  • It would have developing country applications.
  • They would seem to have a large capacity.

I shall be following Malta Inc. with interest.

Have Transport for London Got A Plan To Finish Work On The Gospel Oak To Barking Line?

This article on CityMetric is entitled London’s Gospel Oak to Barking Line Might Be About To Lose All Its Trains To Birmingham.

These two paragraphs outline the problem with the Class 172 and Class 710 trains on the Gospel Oak to Barking Line.

Under Tf’L’s original plans for the GOBLIN, this would have been OK – the current diesel Class 172s were supposed to stay until the new electric Class 710s were in power. But there’s a big shortage of diesel trains in the UK, so the Department for Transport insisted that the 172s went to the West Midlands Railway franchise to boost services around Birmingham. TfL – under the previous mayor, who you may remember from certain gameshows and zipwires – signed up to transfer the trains early.

But the trains aren’t early. Two of the eight 172s on the GOBLIN have already been sent to the West Midlands, which leaves the GOBLIN service a mess because it requires all six trains to run a peak service. TfL is desperately trying to keep the trains running day-to-day by cancelling weekend services.

TfL need to cancel some weekend services, so that they can service the trains properly. I could imagine that of the six trains, that remain in North London, which run in the week, three would work Saturday and three would work Sunday.

Today, they are shuttling between South Tottenham and Gospel Oak stations.

  • The journey takes fourteen minutes.
  • There is a crossover at South Tottenham station, which allows trains to reverse there.
  • I think that two or three trains are providing a two train per hour (tph) service.

I went to South Tottenham station, this morning and there were some fractious relations between customers and staff, but nothing too fractious!

There were also posters on the wall of the station saying that on most weekends until the 20th of January, there would only be services between South Tottenham and Gospel Oak stations.

Closures between South Tottenham and Barking stations are on the following days.

  • 24th December 2018
  • 25th December 2018
  • 26th December 2018
  • 29th December 2018
  • 30th December 2018
  • 31st December 2018
  • 1st January 2019
  • 5th January 2019
  • 6th January 2019
  • 13th January 2019
  • 19th January 2019

The whole line will also be closed on the 20th January 2019.

Note that from now until the 6th January 2019, the trains will only be running for five days out of fourteen. Is this high degree of closure, so that the Class 172 trains can be fully serviced?

It looks to me that TfL are succeeding in providing a two tph service to the West of South Tottenham station.

Note that only Harringay Green Lanes and Crouch Hill stations aren’t direct or out-of-station interchanges.

If you look at the stations to the East of South Tottenham station, you find the following.

To increase services in the area, a Rail Replacement Bus is being run between Walthamstow Central and Barking stations.

The proposed level of service at weekends, should enable.

  • Enough time to maintain the six trains needed for the four tph weekday service on the whole line.
  • Three trains at the weekend to enable a two tph service between South Tottenham and Gospel Oak station.
  • Any outstanding work to be completed on the stations between Barking and South Tottenham stations.

I’m sure that it used to say on Wikipedia, that the new four-car Class 710 trains would be introduced gradually into the fleet.

This would certainly be possible, as the new trains became available and each one that entered service could release a Class 172 train for West Midlands Trains.
