Clean Hydrogen: A Long-Awaited Solution for Hard-to-Abate Sectors?

Hydrogen is a versatile energy carrier that can be produced from a variety of sources, including natural gas, coal, biomass, and water. However, the production of hydrogen from fossil fuels is associated with significant greenhouse gas emissions, which undermines its potential as a clean energy source. Clean hydrogen, on the other hand, is produced from renewable sources such as wind and solar power or through carbon capture and storage (CCS) technologies. This article explores the potential of clean hydrogen as a long-awaited solution for hard-to-abate sectors.

What are Hard-to-Abate Sectors?

Hard-to-abate sectors are industries that are difficult to decarbonize due to their high energy demand and reliance on fossil fuels. These sectors include heavy-duty transport, aviation, shipping, steel, cement, and chemicals. According to the International Energy Agency (IEA), hard-to-abate sectors account for approximately 30% of global CO2 emissions.

The Promise of Clean Hydrogen

Clean hydrogen has the potential to decarbonize hard-to-abate sectors by replacing fossil fuels with a clean energy source. Hydrogen can be used as a fuel for transportation, heating, and industrial processes. When produced from renewable sources or through CCS technologies, clean hydrogen has zero or low greenhouse gas emissions.

The Challenges of Clean Hydrogen

Despite its promise, there are several challenges associated with the production and use of clean hydrogen. First and foremost is the cost. Currently, clean hydrogen is more expensive to produce than hydrogen from fossil fuels. This is due to the high cost of renewable energy sources and CCS technologies.

Another challenge is the lack of infrastructure for storing and transporting hydrogen. Unlike fossil fuels that can be transported through pipelines or tankers, hydrogen requires special storage tanks and transportation methods.

Finally, there are technical challenges associated with the use of hydrogen in existing infrastructure. For example, hydrogen has a lower energy density than fossil fuels, which means that more hydrogen is required to produce the same amount of energy. This requires modifications to existing equipment and infrastructure.

The Role of Policy

To overcome these challenges and realize the potential of clean hydrogen, supportive policies are needed. Governments can play a crucial role in promoting the production and use of clean hydrogen by providing incentives for investment in renewable energy sources and CCS technologies. They can also support the development of infrastructure for storing and transporting hydrogen.

In addition, policies can be put in place to encourage the use of hydrogen in hard-to-abate sectors. For example, governments can mandate the use of clean hydrogen in transportation or provide subsidies for industries that switch to clean hydrogen.

Conclusion

Clean hydrogen has the potential to be a long-awaited solution for hard-to-abate sectors. It offers a clean energy source that can replace fossil fuels and reduce greenhouse gas emissions. However, there are several challenges associated with its production and use, including cost, infrastructure, and technical challenges. To overcome these challenges, supportive policies are needed to promote the production and use of clean hydrogen.
