Since the efforts to decarbonize the transport sector are intensified, hydrogen is a basic solution. This source, which is able to overcome the batteries, is especially promising for heavy vehicles and applications where dense energy is decisive. Scientists from the University of Linköping in Sweden are working on innovative materials capable of producing hydrogen from solar energy and opening a way to the future, where traffic systems could be supported by truly clean energy.
A spectacular improvement thanks to a system of three layers
Scientists at Linköping University have recently introduced significant progress in the production of solar hydrogen. Have developed the structure of the layer by means of carbide of cubic silicon (3c-s), cobalt oxide (co₃o₄₄) and catalytic layer of nickel hydroxide (NI (OH) ₂). This combination of materials allows a significant improvement in hydrogen production.
According to Jianw Sun, the main challenge in understanding is the role of each layer and the way they contribute to optimizing the properties of the material. When exposed to sunlight, the material generates electrical loads that triggers the reaction of water separation in hydrogen and oxygen. The main obstacle in these systems is the complication of the load that can neutralize the efficiency of the process.
“It could feed humanity for 170,000 years”: This forgotten source of energy recovery energy at the right time
By integrating these three layers, scientists have managed to improve the load department and achieve multiplied eight compared to the 3C-Nic itself. This progress could radically transform how we produce hydrogen, and open the way to wider use in the industries where the batteries cannot be used effectively.
Towards a truly ecological hydrogen
Currently, almost all hydrogen is available on the market as “gray” because it is made from fossil fuels. This method emits approximately 10 tonnes per ton of hydrogen producedWhich threatens its role in pure fuel. On the contrary, “green” hydrogen is generated due to renewable electricity, although it often requires other energy sources above simple sunlight.

The aim of the Jianwa Sun team is to reduce this energy dependence exclusively by using solar energy to supply the reaction to hydrogen production. This approach could significantly reduce costs and eliminate carbon emissions Associated with this process and hydrogen formation really ecological.
The target of 10 % efficiency that needs to be achieved
Despite the progress, technology is not yet prepared for commercial exploitation. The current materials used to separate solar water show only efficiency between 1 and 3 %. For “green” hydrogen to be made on a large scale, the materials must achieve at least 10 % efficiency.
Nevertheless, Jianwa Sun is optimistic about achieving this goal. It estimates that it will take five to ten years for the research team to develop materials capable of reaching this long -term limit of 10 %. Such a milestone would be a turning point for the hydrogen economyallowing the production of hydrogen without hydrogen and carbon, sufficiently important for supporting industrial use and transport sector.
A promising future for heavy transport
While electric motors are effective for cars, their energy density and recharging make them unexpected for heavy vehicles, vehicles, boats and aircraft. Hydrogen appears to be a viable solution for these sectorsWhere battery -based systems cannot meet energy requirements.
The development of materials capable of producing hydrogen from solar energy could transform these sectors. If the technology achieves set objectives of efficiency, it could become the pillar of its own energy infrastructure for the coming years. This arrival could allow a truly durable heavy transport, released from the restrictions of fossil fuels and carbon emissions.
As the research proceeds, the question arises: becomes solar hydrogen standard for heavy transport and revolution in how we design and use energy in these sectors?
