Hydrogen technologies refer to methods and systems that utilize hydrogen as a clean energy source. These technologies include the production, storage, and use of hydrogen fuel, which can be generated through processes like electrolysis or steam methane reforming. Hydrogen can power fuel cells, which convert chemical energy into electricity, making it a promising alternative to fossil fuels. In addition to energy production, hydrogen technologies are also being explored for applications in transportation, heating, and industrial processes. As countries aim to reduce carbon emissions, hydrogen is gaining attention for its potential to support a sustainable energy future while minimizing environmental impact.
