The Efficiency Classroom LETTER – UGR moves with you

The collaboration space created between the University of Granada and the company Letter Ingenieros S.L opens a new website to inform about the activities and programs it organizes.

This new portal, which can be accessed through http://aulaletter.ugr.es/, has relevant information for the university community.

Within this community, it is especially designed for undergraduate and master students in Chemical Engineering.

Classroom Programs

Among the programmes that have been launched, the most efficient TFG Award stands out, which rewards projects that take into account the energy efficiency of the main processes.

In this way, it is favoured that the projects that leave this department have a differentiating component that favours the students.

The 2019 edition of the prize has a last generation iPad valued at more than 500€ among other gifts.

Another of the successful programs launched by the Aula are the internships in the company, being this program a help for labor insertion.

Classroom Activities

In addition to these programs, it also organizes activities that encourage students to connect with the company.

Proof of this connection are the Sports Days that are organised this year between teachers, students and company employees.

For this occasion, a bus will be floated on 10/5/2019 to allow students to attend and all participants will be treated to an aperitif at the Vegas de Genil sports facility.

During the day the participants will be able to play 7-a-side football and paddle tennis among other activities.

Classroom R&D

Finally, it should be noted that the website informs of the R&D projects being carried out, highlighting the entitled H2-SMART which can be further information here: https://letteringenieros.com/es/category/hidrogeno/

1ºWorkshop H2Smart project at the University of Granada

1ºWorkshop H2Smart project at the University of Granada

H2 Smart – An energy efficiency model for transport fleets

“The renewable hydrogen as an efficient solution in the design of a Smart City and its positive impact on a new model of sustainable mobility with vehicles emission 0” as a conclusion to a WorkShop, in which representatives of city councils, public entities and companies of Granada participated.

 

Iº Workshop on Hydrogen in Granada, organized by Letter Engineers

Within the framework of the H2 Smart Innovation project, led by Letter Ingenieros and supported by the Smart Cities Cluster of Andalusia and the University of Granada, the first H2Smart Workshop has taken place. in order to further advance the development of feasibility study on hydrogen technology as a real market solution to meet the challenge on the storage of energy from renewable sources.

The meeting, which took place on 12 December in the Cloisters Hall of the Faculty of Sciences of Granada, was a success because it raised a common interest among the more than 30 attendees: MAKE OUR CITIES UN HABITAT FREE NOx , EFFICIENT AND SUSTAINABLE.

The development of the Day.

For the development of the Workshop, Letter engineers opted for an unusual format, organizing attendees in work tables of common interests. The purpose was to reach a final conclusion, elaborated from the different profiles and points of view that were in the room.

In the first place we have the welcome of Mrs. María Carmen Carrión, illustrious Dean of the Faculty of Sciences who showed its sensitivity to renewable energy, research at the university, business involvement and the real possibilities of hydrogen as a totally clean and environmentally friendly alternative in this energy transition. He also thanked the presence of City Councils, Entities and companies.

Subsequently, Dr. Carlos Funes, head of the Open Innovation Unit of the National Hydrogen Center, was responsible for exposing renewable hydrogen technology and the costs of its generation. With this he demonstrated the profitable and ecological application of this technology in fleets of public buses and fleets of garbage trucks. From his speech, two interesting conclusions are drawn for the use of hydrogen in the development and planning of a Smart City:

  1. "The use of renewable energy to produce hydrogen and, in turn, use that hydrogen to the mobility sector can generate a positive business case today"
  2. "The most interesting approach for regions and cities is the production of renewable hydrogen and its consumption in captive fleets of buses and garbage trucks."

Later he spoke D. Juan Carlos García Abril, Director of Innovation and Projects Letter Engineers, who presented the project and its viability Smart H2 for Granada. It is presented as a great solution for the decarbonisation of the city and compliance with restrictive European policies. In addition, Juan Carlos García as a citizen of Granada, highlighted the serious problem of pollution that has Granada and its metropolitan area. Since 2008 the limits in NOx (called the invisible poison) and suspended particles have been exceeded, obtaining values similar to those of Madrid, Barcelona or Bilbao.

TABLE COUNCILS: Moderated by D. German Luzon González, professor and coordinator of Chemical Engineering at the University of Granada, and composed of representatives of various municipalities in the area of Granada. They aimed to know the reality of our municipalities, their concerns and management tools and financing used in the governance of our cities, in order to fit the viability of the H2 Smart project in the planning of Smart Cities. As a most important conclusion, it should be noted that all the representatives of this table agreed on the difficulty of reaching financing or approval of budgets to carry out projects of this nature, since they work more in the face of the citizen, than for environmental improvement a city or town. In addition, both mayors and technical highlighted the lack of staff or external experts in certain subjects, having an engineer for all, and the need to bring these projects through a common and applicable to all regulations. Finally, also it highlighted the lack of awareness in our citizens, not being aware that more than half a million deaths occur annually caused by pollution problems and air quality.

Table participants: Agenda 21 Local Town Hall of Granada, Armilla City Council, Salar City Council, Padul City Council and Albolote City Council.

TABLE ENTITIES: Moderated by Ms. María Ávila Montoro, Commercial Director of Letter Engineers, and formed by public entities of the Granada area. They aimed to know first-hand about future environmental planning policies and the challenges they face as financial managers. This table talked about the funds of aid that, to date, exist to be able to undertake projects of this type. The 20M € that were still available in the announcement for Intelligent Networks (Andalusian Energy Agency) and the Edusi Funds, which contemplate the execution of projects that improve air quality, were highlighted. In conclusion, it was emphasized that have a common strategic plan would be complicated by the multitude of actors are involved in the development of the (City Councils, Transport Consortium Companies, etc).  In addition, it was also specified that, in smaller municipalities, Sustainable Mobility Plans have been developed more focused on Crosswalk, Bike Rails and parking, instead of others aimed at solving the mobility driven by Diesel / Petrol combustion vehicle.

Table participants: Diputación de Granada, Cluster of Sustainable Construction of Andalusia, Provincial Energy Agency of Granada and Inagra.

COMPANY TABLE: Moderated by Don Juan Carlos García Abril, Director of Innovation and Projects of Letter Engineers, and formed by companies from Granada which represent the energy sector of the province. Its aim was to know the business vision of experts in management and installation of renewable energies, on the H2 Smart project and its viability in the province. During the development of this table, all the participants (who in some way generate energy from renewable energy) saw in the H2Smart project the main solution for the storage of energy in the form of renewable hydrogen. On the other hand, the companies highlighted the competitive advantage of hydrogen as a source of motor power in mobility compared to the electric vehicle. And it is that these vehicles not only have greater autonomy if not also have less charging time. On the other hand, the table entrepreneurs showed very interested in knowing actual data for technical and financial feasibility. This was intended to analyze the return on investment and to answer the question of: Would you be willing to invest in hydrogen vehicles? For this, D. Juan Carlos García, invited them to read the Business Plans which have been developed at the National Hydrogen Center.

Table participants: Grupo Cuerva, Construcciones Otero, Andasol, Windhunter, Iberdrola and A.E. Jérez del Marquesado.

End of the day and conclusions:

At 12:20 in the morning it was reached at the end of the workshop with a general conclusion of the three tables:

Renewable hydrogen as a clean energy source and zero-emission cycle, along with other technologies for sustainable mobility is the future in designing strategic plans of our Smart Cities. All this will be possible when a pilot project is developed which demonstrates the technical and financial viability of the great challenge posed by modal changes and air quality

Letter Engineers and Renewable Hydrogen Cell in the Night of the Researchers

Letter Engineers and Renewable Hydrogen Cell in the Night of the Researchers

“If I do not know something, I will investigate it”. Louis Pasteur

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:

  1. The solar module converts sunlight into current
  2. This current is carried to the electrolyser where the water molecule breaks down into hydrogen and oxygen
  3. The gases produced are stored in the test tubes that the electrolyser has
  4. Hydrogen and oxygen are put into the fuel cell where they are converted into electric current
  5. 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.

Nuevo Panorama Energético Español

Energy Transition in Spain. We explain it to you

“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.

Letter Engineers: Five years working with Energy Efficiency

Letter Engineers: Five years working with Energy Efficiency

Letter Engineers celebrates its 5th anniversary in the development of energy projects.

Why an Energy Efficiency company?

Back in 2013, the economic situation of the country caused three young experts in energy matters and with a very different situation, to pose the following question: what now? … a question that was answered with “OTHER COUNTRY”… but these three young people, (María Ávila, Juan Carlos García y Alberto Ochando), were unwilling to have to leave his city, his family, much less abandon their dreams, to answer that dreaded question …

With years of experience in the energy sector they decide to combine their skills, qualities and knowledge to venture into the business world. In this way, LETTER INGENIEROS saw the light with a single mission: To meet legal, energetic and environmental needs of the customers, offering an integrated service of Engineering and Environmental Consulting.

5 years with Energy Efficiency

Now, 5 years later, LETTER INGENIEROS and its more than 20 workers are proud of the way traveled, the projects executed and the energy savings achieved. That is why, and for much more, so from the management team of Letter Engineers, has been launched:

I SPORTS MEETING LETTER ENGINEERS

Next Friday, April 20 at 12:00, on the sports courts of Vegas del Genil, the entire team of LETTER ENGINNERS, will play two tests: in pairs we will conduct a Padel Tournament and by teams we will play a football match.

An event designed to share our happiness with the whole team, day after day makes it possible, those three youths turned into a leader team, continue to believe in the present and continue to bet on the future of LETTER ENGINEERS.
