Recently, the second Energy Transition Working Group (ETWG) conference of the G20 came to an end in Gandhinagar, clearly portraying India as an up-and-coming powerhouse in the energy transition. One of the main topics of discussion during India’s G20 Presidency is the development of a green hydrogen economy. Given the vital role that hydrogen plays in enhancing our energy security and diversity, the development of a strong green hydrogen economy is progressing quickly. However, where and how do we begin?

Definition and Scale

Even within the G20 countries, there is currently no agreed-upon definition or classification of “green hydrogen.” The G20 presidency by India is an excellent chance to encourage member countries to work on a standard and certification procedure that is accepted by all countries. The creation of a transparent, strong, and international marketplace can be made possible by a standardized framework for classifying green hydrogen and its derivatives. This framework can set common standards and give explicit definitions of what green hydrogen and its derivatives are. A unified framework for defining green hydrogen and its derivatives would make it easier to implement targeted policy changes and will give customers, suppliers, and investors clarity and assurance.

The G20 has not yet adopted a specific framework for advancing a green hydrogen economy, although there are numerous existing frameworks for defining green hydrogen and its derivatives. To build a coordinated framework for a green hydrogen standard, we must take use of the ongoing green hydrogen activity in member countries. The framework must emphasize the numerous requirements for sustainable green hydrogen generation that minimizes emissions and other negative environmental impacts. It should do this by drawing on the knowledge and experience of member nations. The framework needs to specify in detail how renewable energy sources (such as wind, solar, geothermal, or hydropower) are used in production processes including electrolysis, bioconversion, and ethanol manufacturing. This would increase trade by facilitating simple and traceable reporting throughout the full certification process.
