6 Frequently Asked Questions about “Hydrogen energy storage patent statistics”
Are hydrogen patents a good indicator of innovation?
Patents are strong indicators of innovation activity which can give very detailed insights into the state and direction of the science. This study, which combines the expertise of the International Energy Agency and the European Patent Office, is the most comprehensive, global and up-to-date investigation of hydrogen-related patenting so far.
What happened to hydrogen patenting in the US?
By contrast, hydrogen patenting decreased significantly in the US after 2015, and the US was a distant third to the EU and Japan in 2020, despite being the main innovator in hydrogen in 2011 in terms of volume of international patent families.
How many international patent families are there in hydrogen technology?
About half of international patent families (IPFs)1 in hydrogen technologies in the period 2011–2020 were related to hydrogen production. The other IPFs were split between end-use applications of hydrogen and technologies for the storage, distribution and transformation of hydrogen.
What is a hydrogen patent?
Their patent portfolios are mainly focused on production by electrolysis and applications based on fuel cells but also extend to established technologies for the storage and distribution of liquid or gaseous hydrogen, an area of focus for these countries which plan to import stored hydrogen in the near future.
Why are hydrogen production technologies becoming more patentable?
Specifically, the growth of patenting in hydrogen production technologies since 2001 has been chiefly driven by the rapid rise of innovation in electrolysis, whereas patenting in hydrogen production from fossil fuels has been decreasing over the past decade after a peak in IPF publications in 2007.
Why do we need patents for hydrogen energy?
Through patenting, inventors seek to ensure that they can recoup these investments in innovation. Coordinating the deployment of the full hydrogen energy value chain is perhaps the most complex of all the technical challenges facing energy engineers and it is sometimes hard to discern the status of all the underpinning technology areas.
