Solar energy is used for large-scale hydrogen energy production, according to a team of researchers at the University of Strathclyde. Even today, hydrogen is one of the country''s cleanest sources of energy. Even today, most of the hydrogen we produce is still from fossil fuels. A shocking analysis from the US Department of Energy shows that natural gas plants are the national source of 95 percent of the hydrogen produced in the country.

These gases are absorbed into the atmosphere as a result of these fossil-fuel-driven hydrogen production methods. This can be prevented if we discover a green and sustainable way to produce hydrogen.

In a recent research published in angewandte Chemie, a science journal managed by the German Chemical Society, scientists at the University of Strathclyde have proposed one of these methods.

The most effective strategy for green hydrogen fuel production

In many previous experiments, scientists have used sacrificial electron donors for hydrogen production.

Although these agents might increase hydrogen yield by reducing electron and hole''s recombination tendency, they couldn''t be used for large-scale hydrogen fuel production. According to a researcher at the University of Strathclyde, storable hydrogen can be produced in large quantities by photocatalysis of water in the presence of sunlight using a particulate conjugated polymer as iridium.

Conjugated polymers (loaded with material like Iridium) have significant potential due to their tunability by chemical synthesis, allowing for better materials design in the future. However, since Iridium is a rare material, Sprick suggests, research will now focus on replacing these rare metal catalysts to help process hydrogen production at a fraction.

According to previous studies, green hydrogen production requires the availability of a wide variety of renewable energy sources. Solar power is a well-known and renewable energy source, and it is available in an overwhelming amount on Earth. Sprick and his team of researchers demonstrate that a photocatalytic splitting of water under the influence of sunlight can be the most effective and efficient way to achieve green hydrogen on a large scale.

The amount of solar energy that comes to Earth in an hour is more than enough to meet global power demands for an entire year. A solar energy-backed photocatalysis is also a very simple and inexpensive technique to produce hydrogen.

According to Sprick, the reported photocatalyst can access solar energy through unfavorable energy injections to create a storable energy carrier in the form of hydrogen from water. The hydrogen then can be converted cleanly into electricity in a fuel cell, with water being the only side-product.

Is green hydrogen the future?

Hydrogen obtained from a solar photocatalysis using a conjugate polymer does not lead to carbon emissions. Additionally, no greenhouse gases are released when this hydrogen is transformed into a hydrogen fuel cell. Therefore, almost clean and green hydrogen production can be achieved using this technique.

Green hydrogen is of great potential as it can significantly reduce our dependence on fossil fuels and reduce the global carbon footprint. Today, industries such as shipping, petroleum refinement, transportation, and aerospace that currently cause a lot of pollution due to traditional fuels can become nearly pollution-free.

Last year, the UK government pledged to generate enough hydrogen for the project to meet the energy demand of three million households. The country''s national grid is also developing a hydrogen-based network to produce clean electricity. France will invest $7.28 billion(7 billion euros) by the end of this decade to achieve its green hydrogen objectives.

Green hydrogen is the fuel of the future, according to many nations and businesses. Its eco-friendly, efficient, and capacity to assist us in reducing climate change efforts. However, researchers at the University of Strathclyde believe that there are still many difficulties in the path of sustainable green hydrogen production, and they are working on these issues.
