Electrification, batteries and hydrogen trains should replace DMUs, says study

Electrification, battery power and fuel cells are the most sensible options for replacing diesel multiple-units, according to an environmental and value-for-money study undertaken by the Association for Electrical, Electronic & Information Technologies.

The «Alternatives to DMUs in Rail Passenger Transport» study was undertaken by VDE with funding from the Federal Ministry of Transport & Digital Infrastructure.

Confirming that electrification would be the best option for meeting targets of decarbonising rail transport by 2050, especially on busier routes, the study recommends that planning processes should be made faster and costs of €2m/km reduced to facilitate wiring of the remaining 40% of the German network.

However full electrification of lightly used routes is unlikely to be economically viable in the foreseeable future, the authors say, and so alternatives ways of displacing diesel traction are needed.

The report says battery operation is the best option for routes with unelectrified sections of up to 80 km, with the traction batteries being charged from overhead lines elsewhere on the route.

Fuel cells are the seen as the best option for routes with long gaps in the electrification, however these would require hydrogen production and supply infrastructure to be put in place.

The report says battery and fuel cell technologies should be equal priorities for development, with political support provided to mitigate implementation risks.

The authors did not consider electro-diesel or diesel-battery options, as rolling stock life-cycles mean these would be a potentially expensive investment in what would only be a ‘transitional measure’.

Doha Metro

Trial operation of the Doha Metro’s Green Line started on December 10, which means all three metro lines in the Qatari capital are now in trial operation.

The 22km line runs from Al Riffa in the northwest of Doha to Al Mansoura and interchanges with the north-south Red Line at Al Bidda and Msheireb, where there is also a connection with the east-west Gold Line.

Trains on the Green Line are now operating between 06.00 to 23.00 from Saturday to Thursday, while services start at 14.00 on Fridays.

In December 2017, Qatar Rail awarded RKH Qitarat, a joint venture of RATP Dev, Keolis and Hamad Group, a 20-year contract to operate and maintain the three-line Doha metro network and the four-line Lusail light rail network.

Scenarios for Crete’s VOAK Motorway implementation via… Attiki Odos

ΒΟΑΚ, Βόρειος Οδικός Άξονας Κρήτης

While the current double tender for Crete’s VOAK motorway axis is essentially considered to be «dead», the Ministry of Infrastructure is preparing the new model to promote the implementation of this major road project.

In fact, there is already some information available on how the new deal will look like. PM, Mr. Kyriakos Mitsotakis has already mentioned that VOAK will be implemented using another concession. And this concession cannot be other than Attiki Odos.

After all, it is a concession that expires in 2024, so the most likely scenario is for Attiki Odos «to be combined» with VOAK Motorway, in order to secure funding for it, thus making it viable and most important, bankable.

The key point

The key point that will define the new tender that will be one and only, integrating the whole axis is the term «viable». Well-informed sources told ypodomes.com that the existing model, in addition to the complex triple process, involved a high participation of the Greek State, an exorbitant subsidy and availability payments that would raise the final cost of the project, higher than any other motorway ever built and operated in the country.

On that basis, the new model will seek a lower participation of the State and funding from another concession contract – most likely from Attiki Odos. In any case, tolls will not be avoided as they were also included in the previous concession tender, at a rate of 0,063 euro/km, as in the rest of the country’s motorways.

However, the participation of a large concession, could bring a reduction to the basic toll fare. What is also known is the intention for the axis construction in 2 phases: firstly the section Chania-Aghios Nikolaos and secondly the extensions to Kolymbari (to the west) and Sitia (to the east). The «unveiling» of the new tender and its architecture are expected by the Prime Minister, probably in early 2020.

MEPs push for high ambitions at the COP25 in Madrid

Πράσινη Ανάπτυξη Φυτό

A delegation from the European Parliament arrived in Madrid yesterday to participate in the COP25, where they will meet with key stakeholders in the negotiations.

An official delegation from the European Parliament will take part in the UN conference on climate change, the COP25, in Madrid in Spain this week from today until 14 December. The delegation is led by Bas Eickhout (Greens/EFA, NL), with Peter Liese (EPP, DE) as Vice-Chair.

The delegation is set to meet with UNFCCC Executive Secretary Patricia Espinosa, IPCC Chair Hoesung Lee, delegates from several non-EU countries as well as civil society representatives.

A press conference with delegation Chair, Bas Eickhout (Greens/EFA, NL), and Commission Vice-President Frans Timmermans is scheduled to take place on 12 December 14.30-15.00 (TBC).

On Thursday 12 December at 12.30, Parliament is hosting a side event in the EU Pavilion focusing on the need to make all countries’ Nationally Determined Contributions (NDCs) more ambitious and on the role that forests play in reaching the Paris target.
Quote

“I am glad that the European Parliament delegation has come to Madrid with a very clear mandate: The EU has to increase its National Determined Contribution to minus 55% greenhouse gas emission in 2030 compared to 1990, and become climate neutral by 2050 at the latest,” says Bas Eickhout (Greens/EFA, NL), Chair of the delegation.

“While technical issues are very important, the most important thing is to continue to work for the common goal, in spite of Donald Trump’s withdrawal from the Paris Agreement. I very much support Ursula von der Leyen’s initiative to have an international alliance to increase ambition in the Nationally Determined Contributions (NDCs). Developments in China, India, South Africa and Canada show that if we act in the right way, we are not the only ones that can be more ambitious.” says Peter Liese (EPP, DE), Vice-Chair of the delegation.
