The greenwashing trap: how green hydrogen can keep its promises

The article highlights how ambiguous terminology in the hydrogen industry facilitates greenwashing, particularly when governments label carbon-intensive blue hydrogen as "low-carbon." This misleading classification exploits public optimism for clean energy while continuing to rely on fossil fuels and unproven carbon capture technologies. The core issue lies in the absence of strict definitions, allowing companies to market dirty hydrogen under the eco-friendly banner of green hydrogen, thereby undermining genuine environmental progress. A critical driver of this problem is the lack of robust, globally standardized emission thresholds for green hydrogen. Without mandatory limits, voluntary certifications and vague ISO standards fail to distinguish truly clean fuel from dirty alternatives, effectively acting as tools for greenwashing rather than protection against it. Recent regulatory efforts, such as the EU’s introduction of "additionality" requirements, attempt to close these loopholes by ensuring green hydrogen production is directly tied to new renewable energy sources. These measures underscore the urgent need for stringent policies that prevent the dilution of green claims through insufficient oversight. To combat skepticism and ensure transparency, the industry must adopt immutable tracking technologies like blockchain to verify emissions data at every stage of production. While technological solutions offer a promising path toward authentic traceability, they are only effective when paired with strong policy frameworks that define and enforce what constitutes green hydrogen. Ultimately, clarity and bold, accurate standards are essential to restore public trust and prevent the clean hydrogen revolution from being sabotaged by deceptive marketing practices.
