Japan and EU Lead the Way in Waterstoff-Related Patents

Japan and the EU are leading in waterstoff-related patents, according to a study by the European Patent Office and the International Energy Agency. Companies from the automotive and chemical industries are the new heavyweights in waterstoffpatents, focusing on electrolysis and fuel cell technologies. Japan has secured 24% of all waterstoffpatents issued between 2011 and 2020, while Germany has 11%. German companies such as Air Liquide, Linde, BASF, Siemens and Bosch are among the world’s leading applicants for established waterstofftechnik. According to German Research Minister Bettina Stark-Watzinger, Germany is well positioned to become a „waterstoffrepublik“ and she pledges to continue funding research to speed up transfer into industry. Japanese and Korean companies such as Toyota, Hyundai and Honda are leading patent applicants.

This article discusses a study which reveals that Japan and the EU are at the forefront of waterstoff-related patents. Companies from the automotive and chemical industries are identified as key players in this field, with Japan having secured 24% of all waterstoffpatents issued between 2011 and 2020. German companies such as Air Liquide, Linde, BASF, Siemens and Bosch have also been identified as world leaders in established waterstofftechnik. The article concludes with German Research Minister Bettina Stark-Watzinger pledging to continue funding research to speed up transfer into industry.

What is Waterstoff?

Waterstoff is a zero-emission fuel source that can be used to power vehicles, generate electricity, and provide heating. It is created through the process of electrolysis, which uses electricity to split water into its two components: hydrogen and oxygen. Hydrogen is then stored in tanks and used as fuel, while the oxygen is released back into the atmosphere. Waterstoff has many advantages over traditional fossil fuels, such as being renewable and producing no carbon emissions when burned. Additionally, it can be easily transported and stored for long periods of time without degrading.
