Hydrogen public transport, a sector in which numerous innovations are emerging, in-depth studies are underway in Italy, in Europe and beyond. There are numerous goals to be achieved and i pilot projects, virtuous, they must become completely ordinary realities in front of which we will no longer roll our eyes as we do now. We begin to see where we are and what awaits us.
Hydrogen public transport: how it works
Buses powered by a mixture of hydrogen and methane, trains that in less than a year will be active, able to move only thanks to hydrogen cells and continuous progress in the production of hydrogen in a less impactful way so that the Hydrogen public transport be possible in all cities and not only in those who have the time, the way and the funds to experiment. There has been no lack of failures, the important thing is that you don't stop trying and that you do it in an increasingly targeted and conscious way.
Hydrogen public transport: buses
Let's find an example of Public hydrogen bus transport in Bologna: this vehicle is powered with a mixture of methane and hydrogen, it is called MHybus and to be correct it must be said that it runs on hydromethane. It was created by Enea, in collaboration with Aster, Sol, Start Romagna and the Emilia Romagna Region, and in 2014 it received recognition from the European Commission as the best initiative on the theme "Environment and climate action" as part of the award "Best Life Environment".
Even though it was an experiment of Hydrogen public transport - we cannot yet speak of continuous service - this exploit has had its importance because it has allowed us to quantify the cost-benefits of a certain type of technology, that based onaddition of hydrogen to methane resulting reduction of CO2 emissions.
Hydrogen public transport: train
The train, the first with hydrogen cells, is arriving in Germany by the end of 2017, even if the French Alstom took care of making it. This kind of Hydrogen public transport on tracks, aims to zero CO2 emissions since hydrogen fuel cells emit only steam and water condensation.
Sound pollution will also benefit as the noise produced by the hydrogen train it will be much less than what we are used to hearing today on board a wagon or near a stretch of railway.
While it's not on its way yet, this train has already made headlines, partially revealing how it works. In acceleration the movement is related only to the fuel cells but as the train approaches a station there lithium ion battery it is partially recharged by a converter. Regeneration then takes place with the recovery of kinetic energy during braking.
For those who find it hard to believe this result in the Hydrogen public transport it will be possible to see it with your own eyes while it will cover its first section at about 140Km / h Buxtehude-Bremervörde-Bremerhaven-Cuxhaven, with a declared autonomy between 600 and 800 km.
Hydrogen public transport in Italy
In Italy we are not stationary, there is a wait for the train, unless overtaking surprises, but the buses are there. In Milan already in 2013, the year in which the first three hydrogen-powered buses arrived and there were already other hybrids in operation.
Another example of Hydrogen public transport successful is that of Bolzano, where we find the first production and refueling station of hydrogen working with renewable sources, close to the Brenner motorway. Refueling station not only for individuals but also for hydrogen buses.
Public hydrogen transport in Europe
On board and in support of the Hydrogen public transport in Europe there are many people and many companies, and also some local administrators who believe in it. Although many projects will not give us a hydrogen bus or train directly, they will be able to facilitate their realization or create the surrounding conditions because theHydrogen public transport become more and more widespread.
For example, there are those who are making membranes for the separation of oxygen and hydrogen, essential in the development of energy production systems from fossil fuels with CO2 sequestration (DEMOYS Project).
In Arezzo, on the other hand, an operational project has started and is divided into 5 sectors: centralized hydrogen storage, network of hydrogen distribution, gas detectors and meters, CHP cogenerators at companies served by the hydrogen pipeline and demonstration laboratory.
Instead, he is engaged in the development of directives and regulations for the approval of hydrogen-powered vehiclesEuropean Integrated Hyrdogen Project (EIHP) whose goal is to arrive at a harmonization of European legislation in this area.
