In the vast universe of energy technology, lithium-ion batteries have reignes supreme for decades. From our mobile phones to electric vehicles, these batteries have been the silent engine that drives our daily lives. But, like any technology, lithium also has its limitations and challenges. What comes next? Join us as we explore the batteries of the future and the alternatives to lithium that could transform the world.
Why look for alternatives to lithium?
Lithium has numerous advantages, but it also presents significant challenges. Lithium can be environmentally costly to extract, and growing demand is putting pressure on global supplies. In addition, lithium batteries, while efficient, have limitations in terms of storage capacity and safety. So what options do we have?
Battery breakthroughs: overcoming challenges for a sustainable energy future
In the search for more affordable and abundant alternatives to lithium-ion batteries, sodium-ion batteries are emerging as a promising option by using sodium instead of lithium as the active ion. Although they do not currently achieve the same energy density as lithium batteries, sodium-ion batteries offer significant advantages in safety and sustainability by using more abundant and less expensive materials. In addition, solid-state batteries represent another innovation by replacing liquid electrolyte with solid electrolyte, improving safety and potentially energy efficiency with higher energy densities and faster charge times, making them ideal for applications in electric vehicles and portable devices. Finally, graphene, known for its ultra-thin and tough structure, is revolutionising energy storage with promises of ultra-fast charge times and long lifetimes, promoting significant advances in consumer electronics and industries, and paving the way for a new generation of more efficient and durable devices.
Beyond batteries: exploring new frontiers in energy storage
While electric batteries have been the mainstay of modern energy storage, relying only on one technology isn´t enough to meet the energy challenges of the future. Diversification of storage sources is essential to create a robust and resilient energy system. In addition to electric batteries, exploring options such as thermal storage and other innovative methods will allow us to make better use of renewable energy, optimise energy efficiency and ensure a constant and reliable supply.
Let´s discover some of these fascinanting alternatives!
Can abundant natural resources be harnessed for energy storage? Air and water prove it!
Compressed air storage (CAES) uses underground caverns or tanks to compress air at high pressure during periods of low electric demand. When electricity is required, the compressed air is expanded to generate power efficiently through turbines, which is crucial for stabilising power grids in areas where topography doesn´t allow for reservoirs. Hidraulic storage, on the other hand, harnesses reservoirs and dams to store and release water on demand, providing stability to the electricity system and facilitating the integration of intermitent renewable enrgies towards a more sustainable and stable future.
Energy revolution: how we cover the peaks of demand with advance technology
In the vibrant world of energy, one of the biggest challenges is managing those times when energy consumption spikes unexpectedly. How do we ensure that our power grid holds up without blackouts?
An alternative can be flywheels, which are notable for their ability to store kinetic energy in a rotating disc and release it almost instantly. But they aren´t the only heroes in this scneario. Supercapacitors, with their ability to charge and discharge energy at breakneck speeds, also play a crucial role in providing a boost of energy when it is needed most.
By integrating these technologies, which are capable of providing large power peaks in short periods of time, with other storage or generation systems, remarkable stability is achieved in electricity grids. This is especially beneficial for small or medium-sized grids that intend to operate in isolation, ensuring a reliable and constant power supply.
Phase change materials (PCM): heat under control and thermal change materials (TCM): efficient storage
Phase change materials (PCM) are substances that store and release large amounts of thermal energy during their melting and solidification process. These materials can be used for applications such as building air conditioning, improving energy efficiency and reducing the need for heating and cooling systems.
Similar to PCM, thermal change material (TCM) store thermal energy, but with different mechanisms, such as absorbing and realeasing heat through chemical reactions. The TCM can be used in thermal energy storage systems for solar power plants, increasing efficiency and storage capacity.
Storage and transport: ammonia and hydrogen. Integrated solutions
Ammonia is emerging as a promising energy carrier. It can be used as fuel directly or as a storage medium for hydrogen. As a liquid at moderate temperature and pressure, it is easier to store and transport than pure hydrogen. Moreover, it can be produced sustainably using renewable energies.
Hydrogen is considered by many to be the fuel of the future. It can be produced from water using renewable energy, stored and then converted back into electricity using fuel cells. In addition, it has thermal and mobility apllications. However, the challenge remains the infrastructure for its efficient and safe production, storage and distribution.
The future of batteries and energy storage is brilliant
The race for the next generation of energy storage technologies is in full swing. With so many promising options on the horizon, the future of portable energy and storage looks brighter than ever. From sodium and graphene to innovative phase-change materials and hydrogen, we are on the verge of an energy revolution.
At CARTIF, we excel with innovative projects that explore advanced solutions for energy storage, such as THUMBS UPand SINNOGENES, among others. These projects reflect our strong commitment to research and development of sustainable technologies that are set to transform the global energy landscape. Keep up to date with the latest news by visiting our blog and website to follow these exciting developments.
‘Innflation’ (innovation + innflation) is the phenomenon whereby an increase in the supply of R&D is not reflected in a reduction in its price because there is a stimulated demand for the purchase of that R&D.
It´s the phenomenon that moves us away from dull innovation systems characterised by continuous price reduction due to oversupply and allows us to have thriving innovation systems characterised by long-term transfer relationships so that the R&D generated is transformed into innovation when successfully exploited.
A dull innovation system, in which the phenomenon of ‘innflation’ doesn´t occur, is characterised by the fact that the public resources allocated to the generation of R&D supply are public expenditure, because the agents that generate that supply are stressed and compete in a red ocean in terms of price. These are innovation systems dependent on the outside world with low and decreasing levels of productivity, characterised by the flight of talent.
“Dull innovation system. Innovation system dependent on the outside world with low and decreasing levels of productivity, characterised by the flight of talent.”
It is therefore a question of implementing dual innovation policies that make it possible to sustain the supply of R&D, but also to stimulate the demand for R&D so that public resources are invested and not spent, to compete on value by creating blue oceans and not on price, undervaluing innovation, to have stimulated and efficient R&D agents, to use our own technology and promote our technological independence, and to have an impact on increasing productivity and retaining talent.
Stimulating demand for R&D must be done through systemic policies with a single, comprehensive visionthat includes:
Attractive tax deduction policies to stimulate new investors in innovation.
Industrial policy to increase the m2 of production plants equipped with their own technology (supply of R&D generated)
Education and employment policies to create and retain talent.
Communication and information policy to create culture, but, above all, innovation discipline.
Policies for the creation of technology-based companies based on the supply of R&D generated.
Stimulating demand will maintain long-term transfer relationships and have a positive effec on ‘innflation’ levels.
Innovate for you, innovate for me, innovate for us.
The construction sector has evolved over the years and, with it, processes and products have gradually adapted to the needs of the market at all times. At CARTIF we have been researching and working in the field of infrastructures and building around thirty years to transform architecture and develop technological solutions focused on sustainable and intelligent construction.
We operate in different fields of application with special emphasis on the sensorisation and monitoring of infrastructures, the integration of renewable energies in buildings, as well as 3D printing technologies in construction, devices and IoT networks (Internet of Things).
On the road to the quest for the smart home, CARTIF researches in building rehabilitation and preventive maintenance, 3D digitisation and measuring, FEM simulation, the development of new materials with innovative properties and solutions for logistics and transport.
A proof of this is the METABUILDING Labs project, where we lead the construction of a network of test benches for façade components.
The main objective of this project, funded by the Horizon 2020 european programme and compound by a consortium of 40 partners proceed of 13 european countries, is contribute a Innovative European Ecosystem and a competitive, sustainable and inclusive grid of Open Innovative Testbenches, that stimulates the inversion of vanguard technologies for building envelopes.
With a focus on optimising the technical and environmental quality of building products, the project consortium is driving the development of these technologies by providing access to services and infrastructure for prototyping, testing and certification. The platform metabuilding.com serves as virtual and unique access to this powerful innovation ecosystem, that includes a wide grid of testing facilities.
In addition, innovative, replicable, standarised and cost-effective facilities known as O3BET (Open Source/Data/Access Building Envelope Testbench) have been desgined and developed during the project to test innovative envelope components under real conditions on a 1:1 scale.
CARTIF has been invovled in the definiton of the requirements and specifications of the prototype of this 03BET and has built the first and only test bench of these characterisitcs in Spain, which is located in the Boecillo Technolgoy Park, next to our facilities. The aim is to continue working on the start-up, the definition of tests and services, the development of the corresponding digital twin, as well as the replication of this test bench, which will be built in seven other countries in the European Union.
This is a milestone that we want to continue to pass on to all companies in the building renovation sector, especially SMEs, to facilitate their access to highly innovative testing tools. And, ultimately, to improve the sustainability of construction.
In a world that is increasingly globalized, the trend to consume local products and opt for short distribution chains has become increasingly relevant. This approach not only has economic implications but also environmental and social ones, positively impacting citizens and the planet. However, this trend is far from becoming our routine food shopping practice.
According to data published by the Spanish Ministry of Agriculture, Fisheries, and Food in 2021, food is primarily distributed through supermarkets, hypermarkets, and discount stores, reaching 73% of sales, while traditional shops distribute 18% of food1. At the European level, direct sales between farmers and consumers only represent 2% of the fresh food market2.
Some forms of selling local or proximity products through short distribution chains include farmers’ markets, direct on-farm sales, or community-supported agriculture (CSA), a model in which consumers purchase subscriptions directly from farmers and in return, regularly receive fresh products like fruits, vegetables, and sometimes meat or dairy during the harvest season.
Consuming local products strengthens the economy of our region. By buying directly from local producers and farmers, we promote the growth of small and medium-sized businesses, generating employment and keeping resources within the community. This cycle of local consumption and production helps create a more resilient economy, less dependent on global fluctuations.
Short distribution chains, characterized by the minimal number of intermediaries between the producer and the consumer, have a direct impact on the freshness and quality of products. By reducing the time and distance of transport, food arrives fresher and more nutritious to our tables. Additionally, this reduction in transport decreases carbon emissions and the ecological footprint, significantly contributing to the fight against climate change.
From a social perspective, local consumption strengthens social ties. Knowing the producers and understanding the origin of the products we consume creates a deeper connection and a sense of belonging and responsibility towards our community. This direct relationship also allows for fairer trade, where producers receive adequate remuneration for their work, avoiding exploitation and promoting decent working conditions.
In terms of sustainability, short distribution chains promote more responsible and sustainable agricultural and production practices. Local producers often adopt more environmentally friendly farming methods, such as organic or regenerative agriculture, which preserve biodiversity and improve soil health. This contrasts with the intensive, large-scale practices of global food industries, which often result in environmental degradation and loss of natural resources.
However, there are barriers that are preventing the take-off of this type of distribution. The main limitations are the small volumes and limited variety of production that are not always able to meet the demand of large buyers, such as in the case of public purchases for hospitals, schools, etc. Additionally, the time and lack of specific producer’s skills can be considered barriers since, besides production tasks, they must perform marketing, advertising, sales, management, etc. Moreover, the higher price and lower convenience, meaning less variety in sizes, formats, pre-processed products, etc., of these types of products make them less adaptable to the lifestyle of many people compared to products sold in large distribution chains. There is also the lesser availability of hours or proximity that these markets can offer the consumer.
Research into how to minimize these barriers is key to tipping the balance towards a more responsible and sustainable production and consumption model in the long term. Greater consumer awareness, along with increased support from public agencies to generate and maintain strategies and actions that support local consumption, are essential.
Many cities and regions are implementing multiple, integrated strategies to promote the shortening of supply chains and stimulate the demand for locally and sustainably produced food. These represent a firm commitment to the development of low-carbon, resilient, and diversified food systems. Some examples are the Strategic Food Plan of Catalonia 2021-2026, the Municipal Action Plan of the Vitoria-Gasteiz Food Strategy 2017-2025, or the Food Corridors Strategy in Coimbra (Portugal).
Some of the actions that are part of these strategies include promoting an online sales network for local products, enhancing the commercialization of local products through the increase and improvement of producer market infrastructures, fair trade fairs, etc., creating a distribution network for local products and facilitating the adhesion of local producers to it, legislating and training public technicians to improve local producers’ access to public procurement, especially in tenders aimed at school canteens, among others.
These strategies and actions are being developed with the participation of many involved actors, from producers to consumer associations, including distributors, food companies, representatives of public agencies, etc., and are equipped with solid monitoring and evaluation mechanisms.
CARTIF, through the FUSILLI project, is working in 12 European cities with the aim of shortening food distribution chains and contributing to the transition towards a more sustainable food system. This set of best practices and experiences are available to be adapted to any other context involved with local consumption and the sustainability of its citizens and planet.
And as an example of our commitment, CARTIF, in collaboration with the Association of Organic Producers Vallaecolid, offers its employees the possibility to buy local and seasonal products weekly and receive them at their workplace. It’s that easy! Are you willing to be part of a similar initiative?

The hydropower sector is a key driver of the energy transition in Europe. In 2022, renewable energies accounted for 41.2% of the total electricity consumption in Europe, with hydropower representing 29.9% of total renewable generation.
As more energy sources are integrated into the European energy landscape, hydropower plays an essential role due to its flexibility. While the generation from other renewable sources like solar or wind is subject to uncontrollable variable weather conditions, it is possible to decide when to turbine the water from a reservoir or river to generate energy. This way, the hydropower sector helps maintain stability in the electrical grid by balancing demand and generation.
Figure 1. Sources of renewable energy in gross electricity consumption in the EU, 2022, Eurostat
In addition to its fundamental contribution to reducing CO2 emissions, this type of energy offers other environmental and socio-economic benefits. It regulates river flows through its dams, acting against flood threats and providing water supply for human consumption and the agricultural sector. Moreover, it can affect the development of local economies by generating employment, retaining human capital, and creating tourist attractions.
Emerging as a fundamental solution in Europe’s energy transition, hydropower is not without challenges and risks: One of the major challenges in Europe is the high age of infrastructures (an average of 45 years compared to 30 years in regions like Asia-Pacific or 15 years in China1), causing inefficiencies in energy production, increased maintenance stoppages, and production costs due to the need for investment and repair.
Additionally, climatic events are making their effects felt in all regions of the world. In Europe, many areas are experiencing more frequent, intense, and prolonged droughts. In the second half of 2022, this situation became evident with a significant reduction in hydropower production, particularly noticeable in the south of the continent, where a near 15% decrease in production was recorded.
Figure 2. Evolution over time of Guadalquivir basin capacity, S.A.I.H Guadalquivir.
This situation necessitates addressing intelligent management of water and hydropower resources. The iAMP-Hydro project (intelligent Asset Management Platform for Hydropower), coordinated by Trinity College Dublin and involving CARTIF, emerges as an innovative response to the challenges facing the European hydropower sector.
Within the framework of the project, a package of digital solutions based on artificial intelligence will be developed, validated in five hydropower plants distributed between Spain and Greece. These solutions will assist plant operators in decision-making by considering environmental and socio-economic factors.
The project includes a predictive maintenance solution through the development of advanced sensors capable of real-time monitoring of the state of turbines and installations. These devices will collect data which, through deep learning-based AI algorithms, will predict possible malfunctions before they occur. This will not only significantly reduce maintenance costs by up to 10% but also enable optimal scheduling of planned shutdowns adjusted to market conditions and socio-economic needs.
Furthermore, a set of specialized sensors will monitor various biodiversity parameters, ensuring that plant operations have the minimum possible environmental impact.

Lastly, CARTIF is leading the use of artificial intelligence techniques and neural networks to create predictive flow models. These models are designed to analyze patterns in historical data, including climate, and will be able to anticipate the potential energy a hydropower plant can generate over the next 7 days. This anticipation will allow for up to 23% more efficient plant operation, ensuring water availability while minimizing waste. In extreme drought situations like those in southern Europe, predictive models are being implemented to assess the short- and medium-term recovery capacity of hydroelectric reserves, considering various climate scenarios and irrigation demands. These models will provide operators with a clear vision of the plant’s evolution in the medium term and allow them to optimize the selection of the most suitable turbines for each operational scenario.
Researchers predict that iAMP-Hydro will improve the environmental and socio-economic sustainability of the current hydropower fleet by reducing operating costs by €1000 million, cutting CO2 emissions by 1,260 tons, creating 10,000 future jobs, and enabling environmentally sustainable flow regulation through digital solutions.
Current estimates show that digitizing the existing 1,225 GW of hydropower worldwide could increase annual production by 42 TWh, equivalent to $5000 million in annual operating savings2.

Water security is an essential concept defined as ´the ability of humankind to protect sustainable access to water, ensuring well-being, livelihoods and socio-economic development´. This concept includes taking measures to protect the ecosystems that provide this vital resource and to secure the ecosystem services linked to water. It is not only about ensuring that there is enough water, but also that it meets high quality standards and meets the agricultural, industrial, energy and domestic needs of a specific region.
The preservation of environmental systems, which constitute the natural sources of water and related ecosystem services becomes essential.
The Global Water Partnership1, an international network dedicated to sustainable water management, describes a water secure world as one in which every person has access to safe and affordablewater for a healthy and productive life, and in which communities are protected from floods, droughts and water-borne diseases. It adds that water security promotes environmental protection and social justice in the face of conflicts over shared resources.

The UN has sounded the alarm about the water deficit that is expected in the future. According to its estimates, by 2030 the Earth could face a 40% deficit if current consumption patterns are not changed. Population growth, especially in urban areas, has increased pollution that affects water quality, not only through air pollution, but also through changes in land use. Water consumption has doubled in the last half century, and it is estimated that by 2025 at least two-thirds of the world´s population will live in areas of high water stress.
Climate change also poses an additional risk to water security, reducing water availability and making it increasingly unpredictable in many parts of the world, leading to major supply problems. In addition, extreme weather events, such as droughts and floods, affect rich and poor alike, disrupting traditional livelihoods and production patterns.
In Castilla y León, water security is already a critical issue, given the importance of our agricultural sector in food production, twhich is highly dependent on a constatn supply of water. The region´s agriculture relies heavily on the production of cereals, wine and horticultural products, and is being affected by climate variability, including prolonged droughts that deplete water resources and jeopardise the sustainability of crops. Similarly, the region is experiencing increasing water stress aggravated by climate change, which threatens food production and affects the balance of the rural economy, thus increasing the already pressing problem of depopulation of our villages or rural environments.
Farmers face an increasingly difficult challenge: maintaining productivity in a context of limited water resources. Many have had to adapt their techniques, investing in efficient irrigation and crop diversification to mitigate the impact of droughts. However, these solutions come at a high cost that not everyone can afford, highlighting the urgency of finding more inclusive approaches. This is where Nature based Solutions (NbS) come in, offering a sustainable alternative to follow.
Source: CARTIF
Nature-Based Solutions are vital to address these problems in a creative way and at the same time provide additional sustainability benefits. UNESCO, in its World Water Development Report, argues that NbS can improve water supply and quality while mitigating the impact of natural disasters. A clear example is restored watersheds and wetlands, which act as natural filters for water purification. By mimicking natural processes, NbS improve water availability and quality and reduce water-related risks.
It is essential to highlight the importance of conserving wetlands and restoring river basins the region, as they act as natural filters, improving water quality and regulating flow in times of drought. Techniques such as agro-forestry and crop rotation can also be explored to maintain soil fertility and reduce dependence on intensive irrigation systems. These practices mimic natural processes and help maintain a balance between production and conservation.
The Global Water Security Index (GWSI)3 , which integrates criteria such as water availability, accesibility, security and quality, standardises water vulnerabilities and risks, helping to identify priority areas where action is urgently needed. This index also highlights the need for innovative strategies that combine green infrastructure with traditional solutions, maximising value for society.

It is also important to highlight the relevance and scope of water security in urban settings, where it encompasses five dimensions: environmental, domestic, economic, urban and resilience to natural disasters. All these aspects make the lack of water security one of the greatest risks to global prosperity and underline the urgent need to take care of the natural resource “water”. This implies sustainbale management, responsible consumption, combating degradation and reuse.
In the Natural Resources and Climate Area of CARTIF, we develop diverse projects related to sustainable water management as basis for water insurance, both for human consumption and for agricultural consumption.
We coordinate the PRIMA NAT-med project, in which we aim to develop, implement and validate a set of Nature-based Solutions, combined in Full Water Cycle-NbS (FWC-Nbs), integrated in existing water infrastructures (grey or natural) and based on specific phases of the water cycle, to optimise the provision of water-related ecosystem services (quality and quantity) and water-dependent ecosystem services (social, economic and environmental aspects), empowering stakeholders and local communities in the Mediterranean region. NATMed will also demonstrate the effect of different SbN-CCA in five case studies located in Spain, Greece, Italy, Turkey, Algeria.
Similarly, through our CIRAWA project coordination work, we work in 8 regions in Cape Verde, Ghana, Senegal and The Gambia to improve agriculture by developing new agroecology-based practices that build on existing local and scientific knowledge to help create more resilient food supply chains in West Africa, and where sustainable water resource management is essential.

From the Natural Resources Area of CARTIF, like many other ´guardians of water`, we work to improve water security, using Nature-based Solutions, as part of our vital commitment to the future of the planet. Only through intelligent and collaborative management can we build a world in which every person has access to water and can live with dignity, ensuring that future generations will also enjoy it.
