Green Hydrogen: The Next Powerhouse in Clean Energy

In today’s rapidly shifting energy landscape, the spotlight is now on hydrogen, especially for its promising capability to address significant energy dilemmas. Just as renewable energy resources and electric vehicles have revolutionized the industry with innovative policy and technology strategies, hydrogen stands poised to join their ranks.

Why Green Hydrogen Holds the Future

Green hydrogen is rapidly rising as a top choice for storing excess energy generated by renewable sources. Imagine harnessing the vast solar energy of the Sahara desert and supplying it to bustling metropolises miles away; this is the potential green hydrogen offers. Long-distance energy transport, especially from resource-rich zones to high-demand regions, is now a feasible vision with green hydrogen.

During the recent UN Climate Conference, the chatter frequently veered towards green hydrogen. Its touted potential to revolutionize major sectors such as heavy industries, maritime transport, and aviation dominated discussions. In essence, the global commitment to a net-zero future hinges on recognizing hydrogen as a pivotal energy source.

International Moves Towards a Green Future

The Green Hydrogen Catapult, championed by the United Nations, recently revealed ambitious targets. Initially aiming for 25 gigawatts of green electrolysers, they’ve now expanded that goal to a whopping 45 gigawatts by 2027. Additionally, the European Commission, taking progressive strides, introduced legislative measures. These aim to promote renewable gases, especially hydrogen, ensuring European citizens enjoy sustainable energy.

Venturing further, the United Arab Emirates is also sprinting ahead, targeting a significant stake in the global low-carbon hydrogen market by 2030. Meanwhile, Japan is laying the groundwork, earmarking a substantial $3.4 billion from its green innovation kitty. The focus? Fast-tracking research, development, and popularizing hydrogen use in the coming decade.

Deciphering the Color Codes of Hydrogen

For the uninitiated, the hydrogen lexicon can be puzzling. Terms like ‘grey,’ ‘blue,’ and ‘green’ frequently pop up. So, what do they signify? Simply put, these colors categorize hydrogen based on its production methodology. Although hydrogen releases mere water upon burning, its production might be carbon-heavy. Consequently, hydrogen could be grey, blue, or even colorful variants like pink, yellow, or turquoise. However, when the goal is a climate-neutral production, green hydrogen emerges as the sole contender – making it indispensable for achieving net zero by 2050.

Expert Insights on Green Hydrogen’s Role

To delve deeper into the significance and workings of green hydrogen, we sought insights from Dr. Emanuele Taibi, a renowned figure in power sector transformation strategies at the International Renewable Energy Agency (IRENA). Based at IRENA’s Innovation and Technology Center in Bonn, Germany, Dr. Taibi is on the frontline, aiding member countries in sculpting strategies for overhauling the power sector. He highlighted the pivotal roles of power system flexibility, hydrogen, and storage in steering the global energy transition. Besides, Dr. Taibi’s contributions to the World Economic Forum’s Strategic Intelligence platform have been instrumental, especially in crafting the roadmap on Hydrogen.
