Abstract
The purpose of this research was to derive promising technologies for the transport of hydrogen fuel cells, thereby supporting the development of research and development policy and presenting directions for investment. We also provide researchers with information about technology that will lead the technology field in the future. Hydrogen energy, as the core of carbon neutral and green energy, is a major issue in changing the future industrial structure and national competitive advantage. In this study, we derived promising technology at the core of future hydrogen fuel cell transportation using the published US patent and paper databases (DB). We first performed text mining and data preprocessing and then discovered promising technologies through generative topographic mapping analysis. We analyzed both the patent DB and treatise DB in parallel and compared the results. As a result, two promising technologies were derived from the patent DB analysis, and five were derived from the paper DB analysis.
Highlights
Hydrogen energy is eco-friendly energy that does not generate pollutants
We try to improve the accuracy of the analysis results by overcoming the limitations of the patent unpublished period by conducting paper analysis
For the analyUS patents published between January 2000 and April 2021 were searched in the WIPS
Summary
Hydrogen energy is eco-friendly energy that does not generate pollutants. Conventional fossil fuels are causing serious problems, as they emit pollutants, such as carbon dioxide, when making energy. Hydrogen produces heat and electricity through a chemical reaction with oxygen. Hydrogen can be stored in large capacities, drawing attention toward it as an alternative beyond the limits of other environmentally friendly energies. The shift from fossil energy to hydrogen energy will change the paradigm of industry beyond technological evolution and innovation and emerge as a major factor that will determine national competitiveness over the generation. It is expected that if even a quarter of the global strategies of various countries are realized by 2030, the transition to a green hydrogen energy society will be solidified, and hydrogen will become the center of a carbon-neutral energy society [1]
