A year ago, at the beginning of 2023, at CARTIF we started one of those great projects that leave a footprint (although if we talk in terms of emissions, the idea is actually to reduce them), NEUTRALPATH. In it, the cities of Zaragoza (Spain) and Dresden (Germany) are developing PCED (clean and positive energy districts) with the aim of becoming pioneering cities in the European Union in terms of climate neutrality and zero pollution by 2030. Istanbul, Vantaa and Ghent join the two aforementioned cities in NEUTRALPATH with the idea of scaling up and replicating methodologies and results in their own city plans.
For those of you, seasoned readers, who are loyal followers of this blog, the idea of climate neutrality and zero pollution in Europe with a target date of 2030 will surely ring a bell. Indeed, NEUTRALPATH is one of those few projects funded by the EU under the umbrella of the “100 climate-neutral smart cities by 2030” mission. The EU has set out to become climate neutral by 2050, and this Mission aims to support, promote and showcase the transformation of 100 pioneering European cities to become climate neutral by 2030, turning them into centres of experimentation and innovation for all other European cities, acting as a mirror for them to look up to and learn from.
Within this framework, research and innovation projects are funded that address:
Clean mobility, e.g. through the use of non-greenhouse gas emitting means of transport, such as electric vehicles or hydrogen or other alternative fuel vehicles, the use of bicycles, scooters and other non-motorised means of transport.
Energy efficiency through the use of technologies and practices that reduce energy consumption and greenhouse gas emissions in buildings and industry through equipment and envelope renovations and the use of renewable energies;
Green urban planning with measures related to the promotion of green spaces, the use of sustainable building materials or the promotion of biodiversity among others.
With these mission projects, the EU also aims to encourage the creation of joint initiatives, cooperation between projects and increased partnerships in synergy with other EU programmes.
Among the 100 cities finally selected to participate in the mission, seven are Spanish: Madrid, Barcelona, Seville, Valencia, Valladolid, Vitoria-Gasteiz and Zaragoza. In CARTIF we are fortunate to have worked directly in different smart city projects with many of them: Valladolid, through REMOURBAN among others, Vitoria-Gasteiz, within SMARTENCITY, Valencia, as part of MATCHUP, or the aforementioned Zaragoza of NEUTRALPATH.
Well, with the recently launched 2024, CARTIF is also launching another of these great reference projects of the mission: MOBILITIES FOR EU, in which two cities that already have the hallmark of mission cities, Madrid and Dresden, will carry out different actions over the next five years to contribute significantly to their transformation towards climate neutrality. I think the name of the project leaves little doubt about the scope of these actions, don’t you think?
For a long time now, we have been hearing various messages about the importance of implementing changes in the form and means of transport we use on a regular basis. So-called sustainable mobility is nowadays a key issue, especially in cities, where transport is responsible for a large part of greenhouse gas emissions. This is why the decarbonisation of transport is one of the main strategies to reduce emissions and combat climate change. Sustainable mobility can help achieve this goal, among others, by reducing dependence on fossil fuels and promoting the use of cleaner and more efficient means of transport.
But in addition to the overall impact in terms of CO2, implementing sustainable mobility measures and policies can also have other direct benefits for citizens, such as improving air quality or reducing noise pollution. Moreover, the impact on people’s quality of life by reducing traffic and improving road safety is also positive.
Sustainable mobility includes a wide variety of actions and strategies, to be developed by both public entities and private companies or initiatives, that seek to reduce greenhouse gas emissions and improve the quality of life in cities and their environments. Some of them could be the promotion of public transport, which is an efficient and sustainable way to move around cities, cycling and walking, which are not only sustainable but also healthy, as well as the implementation of policies that encourage the use of electric vehicles and the necessary infrastructure for their charging and maintenance. Electric vehicles are a cleaner and more sustainable alternative to internal combustion engine vehicles that directly impact air quality in cities. In addition to these, the development of vehicles using other types of fuels, such as hydrogen, is also an avenue of work. The involvement of companies through the generation of their own sustainable mobility plans for staff is also essential to maximise the overall impact. We must not forget that when we talk about mobility, we are talking about people as well as goods. In terms of logistics, it is also necessary to implement measures that make transport sustainable at different stages of the supply chain. In medium-sized and large cities, it is also necessary to take into account the traffic management policies employed at the global and zone level, as these can help to reduce congestion and improve transport efficiency in the city.
In the case of MOBILITIES FOR EU, the focus is on both passenger mobility and freight transport, and its aim will be to demonstrate that different innovative concepts in the field of mobility designed and implemented in an appropriate way and following participatory principles and focusing on users and their needs can help to achieve the desired goal of climate neutrality, and to do so not only with economic viability but also with profitability.
Madrid and Dresden, acting as lead cities of the project, will implement 11 pilots covering 23 highly innovative demonstration interventions for mobility of people and goods, exploiting the combined potential of electrification, automation and connectivity. These include, among others, interventions with autonomous electric vehicles, innovative charging infrastructures, green fuels, electric buses and H2 vehicles, and advanced connectivity infrastructures, 5G and 6G, for connected and autonomous driving. In both cities, they also aim to build on multiple existing citizen cooperation and social empowerment initiatives by integrating them into what we call “Urban Transport Labs” (UT-Labs), conceived as innovation hubs that will aim to foster faster replication at European level. The five replicator cities, Ioaninna (Greece), Trenčin (Slovakia), Espoo (Finland), Gdansk (Poland) and Sarajevo (Bosnia) will be the first to follow the path set by Madrid and Dresden, first as direct participants in the processes of these two leading cities, and in parallel through their own UT-Labs, and later as main protagonists of their own designs. With the same idea of generating impact beyond the framework and the cities participating in the project itself, the aim is to establish collaborative relationships with the Cities Mission Platform to promote the exchange of knowledge and experiences, as well as with the main EU initiatives in this area such as 2Zero and CCAM.
On 30, 31 January and 1 February, all the project partners will meet in Madrid to jointly kick off this challenging project with which we aspire to improve the environment and the lives of citizens. The MOBILITIES FOR EU social networks will soon be launched as the first means of communication and information through which we will share our progress. Stay tuned!
Africa, a diverse and vibrant continent, is in the midst of a unique energy transformation. International organizations such as the United Nations are promoting this energy transition under the philosophy of being just, equitable and “leave no one behind”1. In this blog, we are going to explore the challenges facing this transition, the key factors driving it and how the ONEPlanET project, funded through the Horizon Europe Programme, is supporting this process:
Energy challenges
Growing energy demand: Africa’s population is among the youngest and fastest growing in the world, with a clear tendency to concentrate in cities.
“The energy transition in Africa involves not only decarbonizing, but also guaranteeing universal access”
Limited access to affordable and sustainable energy and lack of clean cooking fuels: inadequate electrification hampers economic and social development in various regions.
Climate Change, with devastating impacts on agriculture or water resources. In addition, the increasingly harsh temperature and humidity conditions will trigger the population’s cooling needs.
Historical dependence on Fossil Fuels: the volatility of oil and gas prices affects the economic stability of many African countries, underlining the need to diversify the energy matrix.
To address these demographic, environmental and socio-economic challenges, Africa will need to double its energy supply by 2040 while ensuring access to electricity for 600 million people and clean cooking fuels for 970 million.2
Key drivers of the just and equitable Energy Transition
Natural resources and renewable potential: despite the enormous potential, to date, only 22% of the total installed energy capacity is based on renewable sources, mainly hydroelectric energy, followed by solar, wind and geothermal.3.
“The energy transition in Africa must consider equity, inclusion and affordability”
Technological Innovation: technological advancement facilitates the implementation of decentralized energy solutions, such as solar microgrids or energy storage systems, overcoming traditional infrastructure barriers in remote populations, and generating new sources of employment.
International Commitments: Growing global awareness of the need to address this transition has led to international agreements supporting clean energy investment in Africa
Renewable Energy potential in Africa is 1,000 times larger than the projected demand by20403 , so the low-carbon pathway is not simply about replacing polluting sources and covering the growing energy demand, but about preventing scenarios where this energy transition triggers conflicts in the use of resources (e.g. hydropower on water use or photovoltaic energy on land use) and seeking for appropriate trade-offs.
ONEPlanET Project
Linkages between key sectors such as water, energy and food require an “integrated Nexus approach”, which guarantees water and food security, sustainable agriculture and energy production. This Nexus approach is the cornerstone on which the ONEPlanET project, is based, in which CARTIF participates along with 11 other entities from Europe and Africa. The project aims at empowering African policymakers, research & academia, investors and citizens with the necessary tools and know-how to increase clean energy generation and sustainable use of resources while reducing inequalities and cultural/socio-economic gaps. Within ONEPlanET, “Water-Energy-Food” (WEF) Nexus models are being developed to support the definition of new policies and planning resilient energy infrastructures..
On November 9, 2023, CARTIF research team participated in the organization of a workshop for the co-creation of these WEF Nexus models in Nairobi (Kenya), attended by actors from the public and private sectors. Their feedback has been key when designing the WEF Nexus models and the subsequent simulation tool. You can click here to watch the video of the workshop.
ONE PLanET Workshop, Nairobi (Kenia), November 9, 2023
In addition, during 2024 students from African universities will carry out research stays in European entities, among which is CARTIF. We are looking forward to welcoming these researchers to our facilities!
In conclusion, the energy transition in Africa does not just imply a change in the way energy is generated, but an opportunity to drive sustainable development and improve the quality of life for millions of Africans. ONEPlanET will contribute to overcoming challenges through the comprehensive WEF Nexus approach, always with the fundamental premise that no individual or community is left behind.
“LA man discovers science-fiction death ray”. This was the shocking headline that appeared in a Los Angeles newspaper in July 1960. A few weeks earlier, on 16 May 1960, the American engineer and physicist Theodore H. Maiman at Hughes Research Laboratories had succeeded in making a synthetic ruby cylinder with reflective bases and a photographic lamp emit pulses of intense red light, the first physical implementation of laser.
Theodore H. Maiman with the first laser implementation
This milestone in photonics was the consequence both of centuries of study by great scientists such as Newton, Young, Manxwell and Einstein trying to understand and explain the nature of light, and of a frantic race since the 1950s between a dozen laboratories, led by Bell´s, to demonstrate experimentally that the stimulated emission of light predicted by Albert Einstein in his 1917 paper “The Quantum Theory of Radiation” was possible.
The termLASER or “Light Amplified by Stimulated Emission of Radiation” was coined by Gordon Gould in 1957 in his notes on the feasibility of building a laser. Gould had been a PhD student of Charles Townes, who, in 1954, had built the MASER, the predecessor of the laser, which amplified microwave waves by stimulated emission of radiation. In 1964, Charles Townes received the Nobel Prize in physics for his implementation of the MASER, Gordon Gould became a millionaire with the laser patent, and Mainman received recognition for having created the first implementation of a laser, as well as numerous academic awards.
A laser is a light source with special characteritstics of coherence, monochromicity and collimation. These characteristics make it possible to concentrate, with the help of optical lenses, a high intensity of energy in a minimum area. To achieve these characteristics, the lase4r makes use of the quantum mechanism predicted by Einstein whereby the generation of photons in certain solid, liquid or gaseous media is greatly amplified when these media are excited electrically or by light pulses.
During the 1960s, in addition to Maiman´s solid-taste laser, other lasers were developed, such as the He-Ne laser in December 1960 and the CO2 laser in 1961, whose active medium was gases, or the diode laser in 1962. Although in the beginning the laser was said to be ” a solution for an undefined problem”, the number of applications of the laser rapidly increased to a great extent, making it an indispensable tool in most fields of science and manufacturing. We can find examples of this industry, where its multiple uses for cutting, welding or for surface treatments of a large number of materiales has made it indispensable, or in the communications sector, where its use as a transmitter of information by means of pulses of light through optical fibres has made it possible to achieve unimaginable data transfer rates without which the current digital transformation would not be possible.
Nowadays, the development of new lasers, their performance and applications continues to grow. For example, in recent years, green and blue lasers have become increasingly important in electro-mobility because their wavelenghts are more suitable for welding copper elements than other more common lasers.

Since 2020 CARTIF is part of PhotonHub Europe, a platform made up of more than 30 reference centers in photonics from 15 European countris in which more than 500 experts in photonics offer their support to companies (mainly SMEs) yo help them to improve their production processes and products through the use of photonics. With this objective, training, project development and technical and financial advisory actions have been organized until 2024.
In addition, to be aware of what is happening in the world of photonics, we encourage you to be part of the community created in PhotonHub Europe. In this community you can be aware of the activities of the platforms as well as news and events related to photonics.
The majority of plastics used in the world today come from non-renewable and non-biodegradable sources. In an effort to reduce the impact of plastics on the environment, alternative methods of production and waste management have been studied for decades. Several microorganisms have the ability to produce plastics naturally, using different substrates, which are biodegradable and biocompatible under certain conditions.
During the last few years, acidogenic fermentation for the production of volatile fatty acids (VFA) has been identified as a promising approach to utilise organic waste as a valuable resource. VFA have a wide potential for applications ranging from carbon source for biological nutrient removal processes to use as a bioenergy resource for the generation of hydrogen and liquid biofuels. VFA-rich streams produced from organic waste fermentation can also be used as biopolymer precursors in the bioplastics industry, as they are a suitable feedstock for the production of polyhydroxyalkanoates (PHA).
To address the growing problem of bio-waste generation and the increasing demand for bio-based feedstocks, the ELLIPSE project is working in the biotechnology sector with the aim of valorising heterogeneous waste streams generated in significant quantities in Europe, slaughterhouse waste (contained in the belly or rumen) and paper and pulp sludge, to produce cost-effective polyhydroxyalkanoates (PHA) for agricultural and personal care applications, through co-processing with other organic wastes such as sludge from the dairy industry and glycerol from the biodiesel industry, as well as nutrient recovery to produce bio-based fertilisers. The integration of these waste streams as biorefinery feedstocks will reduce landfill waste volumes, open up new pathways for the production of chemicals and bioplastics and, at the same time, create additional income for the related industries that generate them, with the added benefits of water recycling, reduced soil degradation, groundwater contamination and methane emissions.
PHA belongs to a family of 100% bio-based polymers with versatile biodegradability properties in most environments, recyclable and exhibiting a wide range of physical and mechanical properties depending on their chemical composition, from the very flexible poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) to the rigid polyhydroxybutyrate (PHB), showing similar properties to some fossil-based materials such as polypropylene (PP) and polyethylene (PE) and better gas and liquid barrier properties than other bioplastics such as polylactic acid (PLA), being a good biodegradable and compostable alternative in agricultural and personal care applications.
One of the objectives is to maximise the production of VFA derived from acidogenic fermentation by optimising the process using innovative technologies, such as the use of an anaerobic membrane bioreactor (AnMBR). The project contributes to the circular economy by promoting sustainability and zero waste by demonstrating the technical feasibility of recovering nutrients from the waste stream (digestate) through a hybrid autotrophic-heterotrophic process of microalgae cultivation, which results in the production of a biofertiliser.
The project has 5 phases dealing with pre-treatment of waste and obtaining VFA, production of PHA, possible applications of bioplastics, life cycle analysis study and exploitation of the results.
Pliot plants of the ELLIPSE project
In Pilot 1, pre-treatment and valorisation of sludge from the processing of slaughterhouse waste for the production of rigid packaging and plastic mulch will be carried out. A co-digestion of raw materials will be carried out in order to ensure the most optimal conditions for producing VFA.
Pilot 3 will be developed simultaneously with Pilot 1 to recover N and P nutrients for biofertiliser production. Different technologies will be validated:
The biological technology of the hybrid autotrophic and heterotrophic microalgae culture system, and the physical methods of pressure-drive membrane technology (ultrafiltration and reverse osmosis) and membrane contactors, to recover ammonia, as ammonium sulphate.
Pilot 2 will treat and recover waste from the paper industry to produce bioplastic coatings for the personal care and agricultural sectors.
The demonstration of the possibility to transform complex bio-waste stream into high-value bio-based and biodegradable products in multiple sectors, accompanied by the validation of multiple end-of life routes for the biobased and biodegradable products achieved within the project will provide novel and tangible results for further promoting public awareness and acceptance of biodegradable and bio-based solutions. Apart from all this, during ELLIPSE project the pulp and paper industry will be able to utilize products (PHA coated paper for flexible packaging as counterpart of current PE coated paper) produced from its wastes. This is a good showcase for circular economy and has the potential to increase awareness and acceptance of bio-based solutions.
These days we are seeing news in the media1 about the possibility of blackouts in the coming years. This news has its roots in a report published by Red Eléctrica de España entitled “National Resource Adequancy Assessment“2 .
It summarises the conclusions of the latest analysis of the system´s ability to safely meet demand. The indicator used to make these estimates is the loss of load expectation (LOLE) indicator. This index measures the number of hours during which, in a given geographical area and in a given period of time, energy production will not be sufficient to meet demand. A LOLE of 0.94 hours/year, is considered acceptable,which means that 99.99% of the time production has to meet demand. However the Red Eléctrica de España report estimates that the LOLE could be 5.63 hours/year in 2024, 6.26 hours/year in 2025 and as high as 7.14 hours/year in 2027 if the planned energy storage is not implemented. In terms of energy deficit, these LOLE translate into 9.38 GWh/year in 2024, 12.9 GWh/year in 2025 and 15.68GWh/year in 2027. The cause of this energy deficit in the Spanish electric system would be the possible dismantling of a certain volume of combined cycle plants that would no longer be profitable due to competition from renewable generation. It would be interesting to know whether the LOLE could be even more adversely affected by the expected closure of Spanish nuclear power plants.
I would like to reflect here on the possible mitigating effect that demand flexibility management could have. As is well known, demand flexibility is the ability of consumers to change their consumption profile in response to a request to do so. Ideally this would be done in exchange for some form of compensation, ideally financial. In a study3 we published a couple of years ago, we concluded that Spanish domestic demand could, thanks to its flexibility, be reduced by up to 2 GWh in winter and more than 10 GWh in the summer months. It is true that these figures would be given in an ideal situation and that they depend on the area of Spain we are looking at. A similar study4 provides more conservative estimates, but these can be as high as 3 GWh depending on various factors. In both studies, flexibility is provided by domestic electrical loads such as heat pumps, air conditioners or electric water heaters. Therefore, flexible energy depends on weather conditions and, of course, on the number of consumers who would like to participate in a demand flexibility management scheme. But above all, it will depend on whether regulation and business models evolve to make it a reality for households and small and medium-sized businesses to be able to offer their flexibility through a mechanism that remunerates them in a way that is not only cost-effective but also profitable. Ways to achieve this goal have been proposed, as in the case of the Entra partnership roadmap5, but Spain is still lagging behind other EU countries on this issue.
For large consumers, there are ways to sell their demand flexibility. In October 2022, the first auction of the new Active Demand Response Service (ADRS) was held, in which 699 MW were offered and 497 MW were allocated at a price of 69.97 €/MW. A new auction is planned for 2023, after the National Commission for Markets and Competition has revised the corresponding regulatory framework6. In addition to this, demand can participate in balancing markets, but the requirement to make minimum bids of 1 MW makes it impossible for non-big consumers to participate. Energy communities or aggregations of consumers are therefore practically excluded from this possibility.
A demand flexibility service that is taking shape is peak shaving. This service, still under study, will reduce peak demand and is designed to facilitate the integration of renewable energies. The service is presented as something that will contribute to energy savings. How much energy can be saved is, for the moment, a mystery. In conclusion, we could say that demand flexibility could mobilise significant amounts of energy, but it does not seem easy to cover the energy deficit that has been predicted in the National Analysis of Coverage of the Peninsular Electricity System, although it could help to alleviate it. To remedy it would require a vigorous regulatory, technological, commercial and social effort to convince as many consumers as possible of the benefits of demand response. This does not appear to be easy to achieve.
In a world where humans perform tasks that involve manipulating objects, such as lifting, dragging or interacting with them (for example, when we use our beloved mobile phones or we eat an apple), these actions are performed subconsciously, naturally. It is our senses that allow us to adapt our physical characteristics to the tasks instinctively. In contrast, robots act like little human apprentices, imitating our behaviour, as they currently lack the same awareness and intelligence.
To address this gap, Human Robot Interaction (HRI) emerged, a discipline that seeks to understand, design and evaluate the interaction between robots and humans. This field had its beginnings in the 1990s with a multidisciplinary approach but today its study is in constantly evolving and has given rise to important events1 that bring together visionaries in the field, who seek to promote this technology, bringing us ever closer to a world where artifical intelligence and humans understand each other and collaborate,transforming our near future.
Understanding the discipline of human-robot interaction is crucial. It is not a simple task; rather, it is tremendously challenging, requiring contributions from cognitive science, linguistics, psychology, engineering, mathematics, computer science, and human factors design. As a result, multiple attributes are involved:
Level of autonomy: decision making indepently
Exchange of information: fluency and understanding between different parts.
Different technologies and equipment: major adaptation between languages and models.
Tasks configuration: definition and execution of tasks efficiently.
Cognitive learning: abilities to learn and improve with time.
Here again, the type of interaction, is of particular importance, which is defined as a reciprocal action, relationship or influence between two or more persons, objects, agents, etc. and a key factor is the distance between human and robot, where it can be called a distance interaction, e.g. mobile robots that are sent into space, or a physical interaction, where the human being has contact with the robot.
Human-robot interaction levels according to standards defined in ISO8373//10218//15066 Source: V. Villani, et al., Survey on human–robot collaboration in industrial settings: Safety, intuitive interfaces and applications, Mechatronics 55 (2018) 248–266,http://dx.doi.org/10.1016/j.mechatronics.2018.02.009
These attributes are just a sample of the complexities involved in these robotic interaction systems, where interdisciplinary collaboration is essential for their evolution.
The challenges of interaction between humans and robots
At the moment the challenges are related to the highly unstructured nature of the scenarios where collaborative robots are used, as it is impossible for a technology developer to structure the entire system environment. Among the most important challenges aspects related to mobility, communications, map constructions and situational awareness.
So, what is the next step in human-robot interaction? Challenges include getting them to speak the same language and improving and simplifying communication, especially for non-technologically trained people, not presupposing these prior skills and not needing complicated instruction manuals; also discovering new forms of interaction, through natural language, in the case of assistive robots, special care for proximity and vulnerability; in general improving interfaces, making them more agile and flexible, so that they can be easily adapted to different scenarios and changes in the environment.
On the other hand, a challenge that has become particularly important in recent times, is to take into account emotional needs, human values and ethics in human-robot interactions, as highlighted in this HRI definition above:
HRI definition (Human-Robot interaction)
is the science that studies people’s behaviour and attitudes towards robots in relation to their physical, technological and interactive characteristics, with the aim of developing robots that facilitate the emergence of efficient human-robot interactions (in accordance with the original requirements of their intended area of use), but are also acceptable to people and satisfy the social and emotional needs of their individual users, while respecting human values (Dautenhahn, 2013).
Inspired by this exciting field of work, CARTIF, in collaboration with FIWARE Foundationand other leading partners in Europe, will start in 2024 the EuropeanARISEproject, which aims to achieve real-time, agile, human-centric, open source technologies that drive solutions in Human-Robot HRI interaction by combining open technologies such as ROS 2, Vulcanexus and FIWARE. And where the aims is to solve challenges by funding experiments that develop agile HRI solutions with increasingly adaptive and intuitive interfaces.
ARISE will address many of the following challenges: (1) Application of collaborative robotics for disassembly of value-added products, (2) Picking of complex products in industrial warehouses, (3) Flexible robotic collaboration for more efficient assembly and quality control, (4) Intelligent reprogramming ensuring adaptability for different products through intuitive interfaces, (5) Search and transport tasks in healthcare environments, (6) Improving multimodal interaction around different functional tasks, (7) Robotic assistance in flexible high-precision tasks, and (8) Improving ergonomics and worker efficiency, thus generating a multidisciplinary framework that takes into account both technological and social aspects.
In addition, the ARISE project opens its doors to robotics experts so that they can collaborate in solving the various challenges, thus generating new technological components for the HRI Toolbox, such as ROS4HRI. This collaborative grand challenge aims to make it easier for companies to create agile and sustainable HRI aplications in the near future.
