The Efficiency Classroom LETTER – UGR moves with you

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/

On the basis of the H2-SMART project, informative talks will be given at the Greencities Málaga congress  and in La Madraza Granada.



Power to gas

Where is the power to gas?

Visit to Energy Park Mainz (Germany)

Wherever the power to gas is there will always be a restless engineer trying to learn and in our team we have several.

As you surely know, we are immersed in a project called H2-Smart where we studied the feasibility of using H2 along with our renewable engerias.

With the intention of learning the secrets of this technology we embarked on a technical visit to the facilities of Energy Park Mainz located just outside Mainz near Frankfurt (Germany).

These facilities have been designed and commissioned by a consortium composed of Siemens, The Linde Group, RheinMain University of Applied Sciences and Stadtwerke Mainz in 2017. (more…)



The role of the price of CO2 in the Energy transition

The role of the price of CO2 in the Energy transition

Putting a price on carbon is an important step, and many in the private sector firmly believe which governments must go in that way to effectively approach climate change – The World Bank

What price must have the CO2 gas to leave out?

Last October 2018 we saw how coal and gas combined cycle acted in support of Spanish electrical system. The funny thing is that this has been going on in recent years. But, according to the government’s plans, this situation may end because, as we know, coal has its days numbered and the gas will be increasingly penalized by the increase in the price of CO2 emissions.

spanish-energy-mixIn December 2018, the UN in its Environment section published the annual disparity report on global emissions, in which 3 scenarios are proposed based on global warming objectives: less than 1.5ºC, 1.8ºC and 2ºC. In addition, the UN talks about urgent and unprecedented measures if we want this to not get out of hand.

On the other hand, the trend of global warming in the period 2014-2017 has been stagnant, being alarmed the increase experienced in this 2018. With these data, it is stated that only 40% of the countries will have achieved their emissions targets in 2020. This report talks of 3 fronts to mitigate the adverse data: effective policies on renewable, efficient transport and forestry.

Instead the study reveals that only 10% of the CO2 emitted globally is penalized with a tax effective enough to encourage not issued. Therefore, in order to achieve the goal of less than 2ºC of global warming, it is estimated that the value of the penalty is between 34-68 € / Ton CO2.


Remember than 1 GWh produced with natural gas emits 202 Ton CO2, more than double if we do with coal. Doing accounts, and knowing the current competitiveness of the gas compared to other ways of generating, we can advance that in penalization ranges above 70 € / Ton CO2, it would not be profitable to generate electricity. Therefore, it is very possible that these plants had to be transformed to renewable gas, such as hydrogen.

In conclusion, I would like us to reflect on these data and we answer these questions. Without policies of penalization to the polluting technologies, a country like Spain will be able to realize a real energetic transition? Did you know the CO2 market and how it works? Do you see it right?

I invite you to leave comments.

Thank you!

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

Reunion Letter H2B2 del proyecto H2 Smart

1st Project Meeting H2 – Smart

The H2 Smart project includes visits to facilities such as those of the Seville-based company H2B2.

This entity is in charge of the manufacture of solutions for the production and supply of hydrogen through water electrolysis, with 3 offices: in Seville, Madrid and California.

H2B2 is a highly qualified and experienced technology company that develops hydrogen production systems based on PEM water electrolysis.

With this visit the company Letter Ingenieros aims to learn first hand several concepts such as:

  • The plant balance used by the Sevillian manufacturer.
  • The ways to establish a mutual benefit.
  • Establishing direct contact between companies.

The meeting had a great explanation from our esteemed colleague Eugenio Trillo, which was nuanced by a great professional of the sector as is Afríca Castro.

During the same it was emphasized that this system is modular and scalable so it is easily profitable.

This type of equipment is not discarded, but in initial projects it is possible to take advantage of smaller facilities while facilities with greater demand can be adapted to larger plants.

The H2B2 professionals also told us that their machines are tested 24/7 to verify their optimum performance and that their control system can connect to the internet and create alerts.

As a result of this visit our vision of your plant balance was more than clear as well as other more commercial aspects.
