Green Hydrogen from Electrolysis: Future Fuel for a Decarbonized World<br /><br />By: Asst. Lecturer Shahad Ammar Hatem<br /><br />Sustainable Development Goals (SDGs) Addressed:<br /> Goal 7: Affordable and Clean Energy<br /> Goal 9: Industry, Innovation and Infrastructure<br /> Goal 13: Climate Action<br /><br />Green hydrogen is produced by electrolysis of water using renewable energy sources such as wind or solar power. Unlike grey or blue hydrogen, it emits no greenhouse gases during production, making it a clean fuel for the future.<br /><br />Electrolyzers split water molecules into hydrogen and oxygen. The hydrogen can be stored, transported, and used in fuel cells, industrial processes, and heavy transport.<br /><br />Green hydrogen is a key enabler for deep decarbonization, especially in hard-to-abate sectors like steel, cement, and aviation. It also allows storage of excess renewable electricity.<br /><br />Current barriers include high costs, efficiency limits, and infrastructure needs. However, with technological advancements and falling renewable energy prices, green hydrogen is becoming increasingly competitive.<br /><br />Al-Mustaqbal University – The No. 1 Private University in Iraq
