Comprehensive analysis of 5,471 patents in the areas of green hydrogen energy from year 2002 to 2022. Classification of water electrolysis (ALK, PEM, AEM, SO, ALL) and system operation (BOP, CON). Natural Language Process (NLP) method for automatic parsing of the patent database.
The global patent trend of green hydrogen by technology areas (or technology subtypes) during the recent 20 years has been presented. The technology type of the system operation showed a ratio of 53% as shown in Fig. 2 (a), while that of the water electrolysis has less than 50%.
Hydrogen production technologies accounted for the largest number of hydrogen patents overall in the 2011-2020 period, and the report finds that across all segments of the hydrogen value chain, low-emission innovations generated more than twice the number of international patents than established technologies.
Technology trend studies on patent analyses of hydrogen technology are critical in understanding the status of present and future technology, as well as, its market opportunity. However, the studies were mostly limited to specific countries and lacked the details of green hydrogen production technology.
The report uses global patent data to provide a comprehensive, up-to-date analysis of innovation in hydrogen technologies. It is the first study of its kind and covers the full range of technologies, from hydrogen supply to storage, distribution and transformation, as well as end-use applications.
The network analysis was utilized to understand high-impact patents as a technical barrier in green hydrogen technologies. A Python script was developed to identify forward and backward relations of a specific patent to others, which was cited by patents in the following years.
