<br />Green hydrogen is one of the most promising solutions for achieving carbon neutrality, as it can play a pivotal role in reducing carbon emissions through several methods, including:<br />1-. Producing clean energy without carbon emissions<br />, green hydrogen is produced by electrolysis of water using electricity generated from renewable sources such as solar or wind energy, which means that the process does not release any carbon emissions, compared to gray hydrogen produced from fossil fuels.<br /><br />2-Use in heavy industries to reduce emissions<br />Fossil fuels can be replaced in emissions-intensive industries such as steel and cement production using green hydrogen, which helps reduce the carbon footprint of these industrial as shown in fi It can also be used in chemical refining and the production of green ammonia to make fertilizers in environmentally friendly ways.<br /> <br /><br />3- Storing renewable energy and stabilizing electrical grids<br />Surplus renewable electricity can be stored in the form of green hydrogen and used later to generate electricity when needed, which enhances the stability of electrical grids that rely on intermittent sources such as solar and wind .<br /> <br /><br />4-Providing clean fuel for the transportation sector<br />Green hydrogen can be used as fuel for hydrogen fuel cells, making it a clean alternative to gasoline and diesel in cars, trucks, trains, and even airplanes, reducing CO2 emissions from the transportation sector as shown in figure (4)<br /><br /> <br />5-Reducing emissions in the energy sector<br />As shown in figure (5), it can be used in natural gas-fired power plants by blending it with gas or replacing it entirely, reducing the carbon emissions of this sector.<br /> <br />Conclusion<br />Green hydrogen is considered one of the essential solutions to achieve carbon neutrality by 2050, as it can contribute to decarbonizing the most polluting sectors, and provides a clean and sustainable alternative to traditional energy, helping to build a more sustainable environmental future.<br /><br />Dr. Qusay Rasheed al-amir<br /><br />جامعة المستقبل الجامعة الاولى في العراق <br />
