A research team at Pennsylvania State University in the United States has developed a new technology that uses sunlight to electrolyze water and generate hydrogen gas. This technology uses titanium dioxide (TiO₂) as a catalyst, which is more efficient at utilizing solar energy than traditional electrolysis. The titanium dioxide catalyst absorbs specific wavelengths of sunlight and facilitates the separation of oxygen and hydrogen during electrolysis. The catalyst is particularly long-lasting and stable, making it more cost-effective to maintain compared to previous catalysts.

The catalyst is particularly long-lasting and stable, making it more cost-effective to maintain compared to previous catalysts.

In experiments conducted at Pennsylvania State University's facilities, it was confirmed that over 80% of the sunlight was efficiently used, with a hydrogen production rate of about 30 liters per hour. What makes this technology unique is that it relies entirely on renewable energy, generating hydrogen without the use of fossil fuels. The technology has also attracted the attention of ExxonMobil, an energy giant, which has formed a partnership with the research team to work toward commercialization. This partnership aims to enable low-cost, large-scale hydrogen production, further promoting the adoption of hydrogen energy.
