The Potential of Hydrogen Technologies in Driving a Low-Carbon Economy

Hydrogen technology refers to the production, storage, and use of hydrogen as a fuel source. Hydrogen is a clean and renewable energy source that can be produced from a variety of sources, including water, biomass, and fossil fuels. Hydrogen can be used in fuel cells to generate electricity, in combustion engines to power vehicles, and in industrial processes. A critical review and feasibility study of existing methods of hydrogen production, storage, and transportation, including their key economic and energy aspects, was presented in a paper by Kindra et al.
The paper reviews the current progress and outlook of hydrogen technologies and their application in power systems for hydrogen production, re-electrification, and storage. The authors conclude that hydrogen technologies have the potential to play a significant role in the transition to a low-carbon economy. The production of green hydrogen must be held using renewable resources (e.g., biomass and water) along with sustainable methods.
The Future of Hydrogen report by the International Energy Agency (IEA) finds that clean hydrogen is currently enjoying unprecedented political and business momentum, with the number of policies and projects around the world expanding rapidly.
The report concludes that now is the time to scale up technologies and bring down costs to allow hydrogen to make a significant contribution to clean energy transitions. Hydrogen energy systems offer ways to decarbonize a range of sectors, including transport, buildings, and power generation.
The use of hydrogen as a fuel source has the potential to reduce greenhouse gas emissions and improve air quality. However, there are still challenges to be addressed, such as the high cost of production and the need for infrastructure development.
