Deep dive into Green Hydrogen.

[YAGAY andSUN]

Let’s take a deep dive into Green Hydrogen, one of the most promising and transformative technologies for fighting climate change.

🌿 Deep Dive: Green Hydrogen – The Fuel of the Future

🔍 What Is Green Hydrogen?

Green hydrogen is hydrogen gas produced by using renewable electricity (such as solar or wind) to split water into hydrogen and oxygen through a process called electrolysis. Unlike “grey hydrogen” (made from fossil fuels), green hydrogen production emits no greenhouse gases.

💡 Why It Matters for Climate Change

• Decarbonizing Hard-to-Abate Sectors: Green hydrogen can replace fossil fuels in industries like steel, cement, aviation, and shipping, which are difficult to electrify.

• Energy Storage: Hydrogen can be stored for long periods, overcoming the intermittency of renewables like wind and solar.

• Clean Fuel: When used in fuel cells, hydrogen emits only water vapor, making it ideal for zero-emission vehicles and backup power systems.

🏭 Applications and Use Cases

1. Industrial Use: Replacing coal in steelmaking or natural gas in ammonia production.

2. Transport: Fuel for hydrogen-powered buses, trucks, trains, and aircraft.

3. Power Sector: Blending hydrogen with natural gas or using it in gas turbines.

4. Residential/Commercial Heating: Hydrogen-based heating systems in colder climates.

5. Energy Export: Countries with abundant renewables (e.g., India, Australia) can become exporters of green hydrogen.

🔧 Current Challenges

• High Production Cost: Green hydrogen is currently more expensive than grey or blue hydrogen.

• Infrastructure Gaps: Limited hydrogen pipelines, refueling stations, and storage facilities.

• Energy Efficiency: Electrolysis and fuel cell conversion involve energy losses.

• Water Use: Electrolysis requires purified water, which may be scarce in arid regions.

🏢 How Stakeholders Can Support Green Hydrogen

✅ For Businesses:

• Invest in Electrolyzer Projects: Manufacturing or partnering in green hydrogen production facilities.

• Collaborate in H2 Hubs: Join hydrogen valley or cluster initiatives to share infrastructure.

• Adopt H2 in Operations: Shift heavy transport fleets to hydrogen-powered vehicles.

• R&D and Innovation: Fund or participate in R&D for cheaper electrolyzers, catalysts, or hydrogen storage technologies.

✅ For Policymakers:

• Subsidies and Incentives: Offer tax breaks, capex support, or contracts-for-difference to lower hydrogen costs.

• Set National H2 Roadmaps: Develop long-term strategies with clear targets (e.g., India’s National Green Hydrogen Mission).

• Create Regulatory Frameworks: Standardize hydrogen quality, safety, blending norms, and transportation codes.

• Invest in Infrastructure: Public funding or PPPs for refueling stations, storage, and pipeline development.

✅ For Individuals:

• Support Green Brands: Choose products or transport services that adopt clean hydrogen.

• Spread Awareness: Share accurate information on the benefits and future of hydrogen.

• Advocate Locally: Push for clean energy choices in community projects or local governance.

🌎 Global Momentum

Countries like Germany, Japan, India, and Australia are leading the green hydrogen charge, with billions invested in pilot projects, hydrogen valleys, and international trade routes. The IRENA and IEA predict green hydrogen could meet up to 12% of global energy demand by 2050 if scaled up efficiently.
