Aenert news. Invention analysisIntroduction Der zunehmende Einsatz von Wasserstoff in der modernen Energieversorgung ist eine Voraussetzung für den Übergang zu kohlenstoffarmen Formen der Energieerzeugung und des Energieverbrauchs. Wasserstoff ist vor allem deshalb einzigartig, weil er sowohl als umweltfreundlicher Kraftstoff als auch als Medium zur Energiespeicherung genutzt werden...

The world's leading patent offices (WIPO, IP5) released key statistics for 2020 at the end of last year. Additional interest in these materials is undoubtedly due to the fact that 2020 was influenced by the coronavirus pandemic and 2019 saw a significant drop in patent activity in China, the most productive country in the world in terms of invention. However, the data presented proved the expected pessimistic predictions wrong. First...

The latest decisions taken on COP-26, including agreements on coal, methane, and limitations on the utilization of fossil fuels make up an important stage in the reduction of greenhouse gas emissions. However, it will take several decades, numerous organizational arrangements, and immense financial resources for a complete switching of the energy industry to renewable sources. This is related to the fact that presently the share of...

Oil and gas production from low permeability plays in most cases requires the employment of directional drilling and hydraulic fracturing technologies. This is necessary to increase the contact area of the well with a formation rich in oil or gas, and to improve the permeability of the rock. Taking into consideration the increase in the share of hard-to-recover reserves in the global hydrocarbon balance, it becomes clear that the use...

As a continuation of the previous review (UNCONVENTIONAL GAS 2019/ key indicators), the results of patenting activity of major applicants from patent applications, dedicated to unconventional gas production including associated petroleum gas (APG), coal bed methane (CBM) and methane hydrates (GHD) are briefly evaluated here. In total, 564 documents were selected for consideration, which were submitted by 270 applicants from 17...

This review provides key statistical results of the analysis of patent applications filed with world patent offices in 2019 on topics related to unconventional gas production including associated petroleum gas (APG), coal bed methane (CBM) and methane hydrates (GHD) which were collected from generally-accessible sources as of the date of this publication. In total, 564 documents were selected for consideration, which were submitted by...

The IP5 Global Dossier Task Force (GDTF) released another progress report on the patent activity of the five leading patent offices of the world (IP5 Offices) in 2019. A total of 2.7 million patent applications were filed and 1.25 million patents were granted at USPTO (USA), EPO (Europe), CNIPA (China), JPO (Japan) and KIPO (South Korea). As for patent applications, there is a slight decrease in the number of documents – one year...

Hydrogen production via electrochemical water splitting is a promising area for storing solar energy. For this technology to be economically competitive it is crucial to develop water-splitting systems with high solar-to-hydrogen (STH) efficiencies. Usually, expensive solar cells or costly semiconductors are used for this. Now (2021), scientists at the Brookhaven National Laboratory have demonstrated that modifying the top layer of...

The proposed review provides statistical data on patent applications registered in patent offices around the world in 2019, and is related to the subject of wind energy, mainly to applications concerning horizontal axis wind turbines which were found as the result of a deliberate search and processed on the date of this publication. In total, the patent search resulted in 2125 patent applications published in 23 offices around the...

The present review includes key indicators of patenting activity of inventors in the field of wind energy in 2019 that were found as a result of a deliberate search and processed on the date of this publication. 2125 patent applications with technical content related to horizontal axis wind turbines registered in 23 patent offices around the world during the year under consideration were collected for the analysis. Almost 500...
