Eutectic electrodes for photoelectrochemical water splitting and hydrogen generation

Green Hydrogen from a Polish Laboratory – Science on the Path to Commercialization

Hydrogen production using exclusively solar energy and water - this is the goal of research conducted by Dr. Jarosław Sar from the Ensemble3 Centre of Excellence. The technology he is developing joins the global race for so-called green hydrogen, considered one of the key fuels of the energy transition.

Unlike conventional hydrogen production methods, the solution being developed by Dr. Sar requires neither fossil fuels nor energy-intensive industrial processes. Sunlight is the sole power source, making this technology exceptionally attractive from both ecological and economic perspectives.

The results of the research to date have been recognized by the Foundation for Polish Science, which qualified Dr. Sar and his team - Wojciech Wegner (Technology Transfer Manager) and Marcin Zimny (Business Leader) - for the first edition of the PRIME program: a science commercialization support initiative funded by the European Funds for a Modern Economy (FENG) program. This program combines the development of scientific competencies with practical preparation for bringing technology to market.

Dr. Jarosław Sar's research into advanced photocatalytic materials allows solar energy to be used to split water into oxygen and hydrogen - without additional energy sources and without environmental burden. The core of the research involves the application of photocatalytic materials (composites consisting of various material types, including single crystals) that combine the ability to absorb sunlight and convert it into chemical energy. Thanks to these properties, it is possible to carry out the photocatalytic process of splitting water into hydrogen and oxygen. This breakthrough approach enables the production of green hydrogen - the fuel of the future - without fossil fuels or additional external power supply. This approach could revolutionize how the world generates and stores clean energy.

The research utilizes single-crystal structure materials that combine the characteristics of different components, giving them exceptional stability and efficiency in long-term photocatalytic processes. Dr. Jarosław Sar is conducting tests to optimize material configurations in order to achieve maximum water-splitting efficiency and electrode durability under varying environmental conditions.

"The biggest surprise in our research was that the longer the process lasted, the more efficient the materials became. This is proof that we are still uncovering their immense, untapped potential," emphasizes Dr. Jarosław Sar.

The outcomes of the research can bring tangible benefits to society - ranging from lower energy production costs and reduced carbon emissions to creating new opportunities for the chemical and energy industries. In the long term, this technology could become one of the pillars of global decarbonization.

Within the PRIME framework, the three-person team focuses on developing a commercialization strategy and building the competencies necessary to effectively translate research results into industrial applications.

PRIME is the only "tailor-made" acceleration program for the transfer of knowledge and technology for scientists and their research organizations in Poland, offering support for an individual commercialization path for innovative products. The program provides the opportunity to both develop competencies (e.g., training) and acquire practical skills (e.g., talks with potential recipients). For the authors of the best ideas, individualized support is provided to implement the chosen commercialization path. The PRIME project is financed by the European Funds for a Modern Economy (#FENG) program. The project is implemented by the Foundation for Polish Science (#FNP).
