BAKU, Azerbaijan, Jan.10. In contrast to the US and European countries, hydrogen innovation is more concentrated geographically in Japan, R. Korea and P.R. China, with a small number of very large regional clusters, Trend reports with reference to the International Energy Agency (IEA).
IEA report reveals that four Japanese regions feature among the top ten global clusters, including Tokyo and Osaka at the top of the list.
“Apart from Tokyo, patenting activities related to hydrogen have increased rapidly in these regions, typically with a strong focus on end-use applications of hydrogen. Seoul is the only cluster identified in R. Korea, with a similar focus on end-use applications.
It stands out with a very rapid growth of patenting activities in the period 2011–2020 and an important contribution by public research institutions to these activities. Another fourteen clusters have been identified in the US, of which two (New York and Houston) feature in the global top ten. These two clusters show a specialization in established hydrogen production technologies. Unlike other major clusters in Europe and Asia, they did not experience a significant growth of patenting activities during the past decade,” the agency says.
