Pioneers in hydrogen technologies and international energy generation projects

Cidaut guides this strategic line towards hydrogen technologies, energy efficiency and the energy use of waste.

Hydrogen technologies

Our experience of more than 20 years in R&D projects in H2 covers the entire value chain, including both projects for the development of fuel cells and use of hydrogen, as well as H2 generation technologies (reforming, electrolysis and thermochemical cycles ). Also projects to integrate H2 technologies in different applications in sectors such as mobility and industry.

Hydrogen technologies in various applications

The projects cover integrations in both the transportation sector and the residential-industrial sector.

  • Experimentation on electrochemical systems based on H2.
  • Development of components and systems for water electrolysis.
  • Design, development and manufacturing of H2 generation systems from renewable substance reforming technologies.
  • Development of synthesis processes for carriers (Methane, Methanol, NH3), and their subsequent cracking and use in various thermochemical and electrochemical applications.

  • Development of pressure H2 storage devices.

  • Development of stacks and fuel cells for specific use requirements.
  • Integration of H2 and fuel cells in systems for electricity generation with application to the transportation, industrial and building sectors.
  • Design of combustion systems for pure H2 and mixtures of H2 with other fuels for application in thermal equipment and thermal engines.

Energy efficiency

Cidaut has extensive experience in energy efficiency, addressing R&D projects in energy generation, exchange and efficient use. Apply this experience in residential and industrial settings, developing comprehensive systems that combine renewable and conventional energies. Additionally, it focuses on monitoring and control research, efficient materials, energy audits and simulation tools.

Currently, Cidaut's actions focus on:

  • Development of solutions for buildings in the field of almost zero energy consumption (nZEB)
  • Development of applications for intelligent building management in 4.0 schemes.

Energy use of waste

Within this line of work, Cidaut focuses its efforts on the use of organic waste of urban origin and lignocellulosic waste to obtain e-fuels and their transformation into products with greater added value.

Infrastructures and laboratories

The HyCID experimental laboratory includes equipment for the research and development of hydrogen technologies linked to both electrochemical and thermochemical processes.

There is also equipment for the supply of hydrogen and other gases:

  • On-site hydrogen generation facility using alkaline electrolyzer for the production of 8,6 Nm3/h of H2 and hydrogen compression and storage system at a pressure of 30 -400bar (up to 55 kg of H2).
  • Instrumented gas supply lines H2, CO2, O2, air, N2 for different configurations of experimentation.

Carrying out tests and developments for the use of electrochemical H2 from a scale of monocells, stacks or complete fuel cells with their entire plant balance. These are testing facilities for energy systems based on hydrogen and fuel cell technologies.

Equipment that includes:

  • Electrical load emulation up to 250kW
  • AVL PUMA® Fuel CellTesting Fuel Cell Testing Interface
  • Equipment for electrochemical studies of single cell and stack up to 5 kW
  • High precision and high sampling rate (1-2MHz) LV measurement equipment
  • Equipment for high power complex impedance testing (current ripple amplitude 60 Amps peak to peak) in stacks
  • 200kW cooling tower for thermal dissipation, safety PLC.

Carrying out tests and developments linked to thermochemical processes with H2: use of H2 as fuel from a thermal point of view; development of conversion processes to carriers (ammonia and methanol); and subsequent use or conversion to H2.


  • H2 combustion boiler and GN+H2 mixtures and heat exchange system: cylindrical hearth 1,5 meters long and 0,5 m in diameter provided with a refractory lining to withstand the high temperatures of internal combustion (up to 1.800ºC ). It includes five large viewing windows for combustion analysis using the multispectral thermal imaging camera.
  • Multispectral camera for combustion analysis: TELOPS IRC-FAST-Multiespectral M350 16 GB. It allows the scene to be divided into eight spectral bands instead of a single broadband image for the analysis of different species. It has different filters to analyze the distribution of species during the combustion process.
  • Gas analyzer: MicroGCAgilent 990 with two carrier gases (Ar and He) and four channels to provide a greater spectrum of measurement compounds such as CO2, CO, CH4, C2-C4 hydrocarbons, H2S, NH3, H2, N2, O2, polar compounds such as ethanol, methanol, acetone and acetic acid. It allows the measurement of gases containing NH3 and its quantification has been incorporated.
