Calculation Of The Emissions Of The Ave To Malaga

@twenergy #sustainablemobility

Last month we traveled on the AVE from Madrid – Malaga on the occasion of the visit to the Malaga Smart City, all magnificently organized by the friends of  twenergy.com. During the journey, we were able to know first-hand that the emissions of this train trip are Zero. We explain why.

In 2012, Renfe signed an electricity supply contract for the  Corredor Sur that  certifies that the energy supplied comes from 100%  renewable energy , certified by the CNE.

The  electromobility  makes Renfe AVE services are much more eco – efficient than other modes of transport as a consumption per passenger transported 36 KWh, 6-7 times lower than those in the car or plane.

The emissions of this AVE are 20% lower than those of the conventional train that operated in the corridor before December 2007, when the Madrid-Malaga AVE service came into operation. This line carries an average annual figure close to 2 million passengers, managing to remove a good part of the passengers from the plane. It is estimated that about 7,000 flights a year have been avoided, responsible for emissions of 76,000 tons of Carbon Dioxide. For comparison, they are equivalent to the annual electricity emissions of all homes in a city like Córdoba (350,000 inhabitants).

Why is the AVE a sustainable mode of transport? 

Integrated design  between the trains and the infrastructure itself.

– It is an  electric vehicle ; that innovative and sustainable technologies have been used for its implementation  ; and that its  management and operation are guided by eco-efficient criteria .

– Lower consumption of auxiliaries.

– Adapted infrastructures with lower slopes, curves and distances.

One of the most innovative technologies they use is the regenerative brake  or KERS. A technology that allows the electrical energy generated in the braking process to be returned to the grid. It is equivalent to an average of 10% of the total energy consumption of the AVE. Unlike the KERS used in Formula 1 cars, the energy regenerated by high-speed trains can be returned directly to the general electricity grid, and can be used by other consumers. It is a technology that Renfe has used in its trains since the 1990s.

Efficient driving in these trains reduces their energy consumption by 15%. In addition, the rate of use of this AVE, 65%, doubles that of other European operators, thus reducing emissions per passenger by half.

The use of electric traction allows Renfe to be the only mode of transport in Spain that uses renewable energies in a significant way. The location of the train stations in the center of the cities makes this trip contribute to a more sustainable mobility of its travelers, being connected to a great variety of public transport.

Proof of this, last September, the first railway station in Spain, a recharging point for electric vehicles with energy recovered from the regenerative braking  of trains , was inaugurated at the Malaga Station “María Zambrano”  .

In short, a recommended means of transport for those who want sustainable mobility for our trips.
