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.
What happened to hydrogen patenting in the US?
By contrast, hydrogen patenting decreased significantly in the US after , and the US was a distant third to the EU and Japan in , despite being the main innovator in hydrogen in in terms of volume of international patent families.
What is a hydrogen storage power system?
The power system containing hydrogen storage can be divided into power generation, energy storage, or load according to the different parts. Ensuring the system's safe operation and achieving the system's operating goals requires an appropriate energy management control strategy.
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.
How many patents are there in Green Hydrogen Energy?
Comprehensive analysis of 5,471 patents in the areas of green hydrogen energy from year to . 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.
Which companies have patented hydrogen technology?
Two Japanese companies – Toyota and Honda – as well as R. Korea's Hyundai stand out. All three feature in this list thanks to patent portfolios in established technologies for the storage, distribution and transformation of gaseous or liquid hydrogen.
