What is the European Night of the Researchers?
In its seventh consecutive year, the european night of the researchers is a night in which both men and women do science for you. The main aim is to approach science and researchers to the general public in order to prove, in a practical and playful way, the relationship between research and daily life, and disseminate scientific investigations among young people.
This initiative is a European scientific dissemination project promoted by the European Commission within the Marie Sktodowska-Curie actions of the Horizon 2020 program, which it takes place simultaneously in over 340 European cities since 2005.
Letter Engineers and the experiment for the night of the researchers
In this edition of 2018 Letter Engineers participates together with the University in an experiment in which we will make renowable hydrogen and, subsequently, energy in a fuel cell.
The process can be seen in the following scheme:
- The solar module converts sunlight into current
- This current is carried to the electrolyser where the water molecule breaks down into hydrogen and oxygen
- The gases produced are stored in the test tubes that the electrolyser has
- Hydrogen and oxygen are put into the fuel cell where they are converted into electric current
- The current produced lights the lamp
We filled the electrolyser with about 50 ml distilled water.
The solar module should be tilted towards the highest radiation to generate between 150 and 350 mA at a voltage of 2.4V. This can be seen with the ammeter.
At about 10 minutes we will see the water bubble and, on each side of the electrolyser, we will collect both gases. We will be producing about 3 ml of hydrogen.
Do you want to see how this renewable hydrogen battery works?
We are waiting for you this afternoon at 18:00 in the STAND 8_UGR.

“The most difficult thing is to leave from a model where there is a series of investments and positions created, towards another much more plural, diverse and positive energy model”
“It’s time for sustainable development” words of Teresa Rivera, Minister of Energy and Environment.
For any citizen is becoming common to hear talk about “decarbonisation of energy”. Mainly we need energy for the buildings and for the transport leaving aside other uses such as the industrial one. We are going to focus on analyzing what is happening in these two sectors with the energy transition that we are already experiencing.
To understand the concept of decarbonisation we have to comprehend which the energy we need is obtained from fossil fuels (coal and gas in combined cycles), nuclear or renewable energy plants. According to the recent report by Spanish Red Electrica (REE) electricity demand in 2017 was supplied as follows:
The new Government, with Minister Teresa Ribero at the head, has already indicated its intention to finish in less than 10 years (2028) with the coal and nuclear power plants. We quickly realize that we will need 38.1% of the 252 TWh of current annual demand. We can already get an idea of the potential that renewables have in this transition.
On the other hand we have the issue of CO2 emissions. We all know which the nuclear ones do not have emissions and they contribute to reduce the global compute. This year we have increased our emissions by 5% and is expected to continue being done in the coming years. Therefore it is very important which everything is done very well analyzed as it is also expected that the ton of CO2 will pass in a few years to cost € 30 to € 100. Yes, you listened well, we paid for the emissions. We even pay for nuclear waste, in this case € 75,000 / year to France.
According to the International Labour Organization, throughout this transition process will be created four posts jobs for every one destroyed. The sectors with more opportunities: renewable in buildings, sustainable mobility with electricity and gas, energy management active and intelligent of smartcity. Among them are synergies as the exchange of energy between cars, urban equipment and buildings, all aimed to build cities of the future in which the citizen owns his energy, produce and consume.
