Fig. 3 depicts the patent activity trend by countries, with China leading in granted patents for hydrogen production technology, followed by the United States. Notably, China has shown a substantial increase in patent activity starting from 2017, continuing to surge until 2022.
Abstract. Hydrogen is a promising future energy carrier due to its high energetic content and sustainable appeal when produced via clean manufacturing processes. One of the technological
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
While Japanese and German organizations still represent the most active applicants, patents are also filed by other companies than in general hydrogen patents – and a French institute leads the list. Our findings are partially consistent with those of
Japan has the most patent applications (49%), but China has the highest growth rate here. Chanchetti et al. (Chanchetti et al., 2016) took a detailed look at

Overall patent trend for HSM. The worldwide number of HSM patent documents increased rapidly in the initial periods, peaked in the 2006–2009 interval, and decreased in the 2010–2013 period, as shown in Fig. 5. In fact, HSM technology developments experienced a steep increase in the late 90''s and early 2000''s.
Hydrogen technology development is shifting towards low-emissions solutions such as electrolysis, according to a joint study of patents by the European Patent Office (EPO) and the International Energy Agency (IEA). The report is the first of its kind and uses global patent data to provide comprehensive up-to-date analysis of innovation in all
SAYUMI TAKE, Nikkei staff writer January 10, 2023 16:19 JST. TOKYO -- South Korea and China are speeding up innovation in hydrogen technologies alongside major players Europe, Japan and the U.S
This study presents the technological S-curves that integrates the Bibliometric and patent analysis into the Logistic growth curve model for hydrogen energy and fuel cell technologies and identifies the optimal patent strategy for the fuel cell industry, including PEMFC, SOFC, and DMFC/DAFC., and DMFC/DAFC.
The leading countries in Europe are Germany (11% of the global total), France (6%), and the Netherlands (3%). The United States, with 20% of all hydrogen-related patents, is the only major innovation
It covers technologies for the full range of hydrogen supply, storage, distribution, transformation and end-user applications, as well as introducing new search strategies to
Currently, there are many methods of hydrogen storage such as compressed hydrogen (CH 2), liquified hydrogen (LH 2), solid state hydrogen storage (SSHS), LOHCs and underground storage [22]. Traditionally hydrogen has been stored as a compressed gas or liquid to increase its storage density, at pressures up to 700 bar [ 30 ].
According to a joint study by the European Patent Office (EPO) and the International Energy Agency (IEA), Europe has filed 28% of hydrogen patents
Many developed and developing countries are the forerunners of reimaging their country''s energy portfolio by creating and funding innovative hydrogen initiatives. Some of these national or international programs include, the United States of America''s "Hydrogen Hubs", European Union''s "Hydrogen Accelerators", and Africa
In terms of hydrogen storage, Toyota holds patents on all options, but the patents concerning storage alloys stand out. Especially in the period 1997–2004, the Toyota data show a peak for this option. 6 However, after this peak, interest in gaseous (since 2004) and liquid hydrogen (from 2007) takes over.
hydrogen to its storage, distribution and transformation, through to its end-use applications across many different industries. Because patent information is the earliest possible signal of industrial innovation, this report offers a unique source of intelligence on a
The report finds that global patenting in hydrogen is led by the EU and Japan, who account for 28% and 24% respectively of all IPFs filed in this period. Both
To address the need for advanced energy storage technologies, DOE has been increasing resources, funding, and public engagement activity in this area. In 2018, Congress passed the DOE Research and Innovation Act,9 and as part of this codification, the DOE''s Research and Technology Investment Committee (RTIC) launched the Energy
Saudi Arabia is next on the list, thanks to the fact that it''s currently building the world''s largest green hydrogen project. A joint venture between ACWA Power, Air Products and Neom, the huge facility will include " up to 4 gigawatts of solar and wind energy to produce up to 600 tonnes" of green hydrogen per day.
Most of the world''s hydrogen-related patents were distributed between the Europe, Japan, and the United States as of the end of 2020. Basic Statistic Average retail electricity prices by sector in
the future output power and hydrogen production per unit of time, allowing the system to achieve dynamic optimization and maximize the use of the input wind energy [33]. Hitachi, Ltd. designed a
The two objectives of this paper are to identify possible sectoral shifts and employment effects due to the application of hydrogen in the energy system for selected European countries till 2030. This is based on assumptions about the market penetration of hydrogen as an energy carrier, an analysis of the competitiveness of EU countries in
609 hydrogen production patents are confirmed to be associated with HFTO funding (380 U.S. patents, 117 EPO patents, and 112 WIPO patents). 224 hydrogen storage patents are confirmed to be associated with HFTO funding (143 U.S. patents, 37 EPO
Currently, the main hydrogen storage technologies are high-pressure storage, liquid hydrogen storage, metal hydride storage, chemical hydrogen storage, and solid-state hydrogen storage [4]. High-pressure hydrogen storage, the most common method, requires specially designed pressure vessels that can withstand pressures from
Hydrogen is one of the most popular energy carriers because of its advantages, including various energy storage methods, high efficiency, and high energy density. Hydrogen has also emerged as a crucial renewable energy system component [[13], [14], [15],,,
