According to GlobalData’s Technology Foresights, which uses over 201,000 patents to analyze innovation intensity for the oil & gas industry, there are 65+ innovation areas that will shape the future of the industry.

Green hydrogen synthesis is a key innovation area in environmental sustainability

Green hydrogen synthesis essentially involves electrolysis of water. When an electric current is passed through water in an electrolyser system, the molecules are split into hydrogen and oxygen. If the electrical energy consumed during the electrolysis process is derived from renewable energy sources, the produced hydrogen is categorised as green hydrogen.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 495+ companies, spanning technology vendors, established oil & gas companies, and up-and-coming start-ups engaged in the development and application of green hydrogen synthesis.

Key players in green hydrogen synthesis – a disruptive innovation in the oil & gas industry

‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

Patent volumes related to green hydrogen synthesis

French Alternative Energies and Atomic Energy Commission, Siemens, Saudi Aramco, Repsol, and TotalEnergies are among the key patent filers for green hydrogen synthesis.

Siemens entered a joint venture partnership with Air Liquide to produce industrial-scale renewable hydrogen electrolyzers. Production of electrolysis stacks at their multi-gigawatt electrolyzer facility in Berlin is expected to start in 2023 and ramp up to an annual production capacity of three gigawatts by 2025.

Saudi Aramco is the leading crude oil producer in the world. It is focusing on hydrogen as an alternate energy source and pursued green hydrogen technology development, announcing several green hydrogen projects, including its ambitious Neom Helios hydrogen project. This is in line with Saudi Arabia’s long-term goal of being a major supplier of green hydrogen.

Repsol has partnered with Spanish gas provider Enagas and other research institutes to develop hydrogen technology. As part of its hydrogen strategy, the company will invest EUR2.5 billion (US$2.9 billion) in the hydrogen value chain by 2030.

TotalEnergies is involved in the H2 Mobility joint venture in Germany, with Air Liquide, Linde, Daimler, Hyundai, OMV, and Shell, to develop hydrogen mobility. In January 2021, the company signed a cooperation agreement with Engie to develop, design, build, and operate the Masshylia green hydrogen project in France.

In terms of application diversity, The French Alternative Energies and Atomic Energy Commission leads the pack, while Toshiba and De Nora Permelec stood in the second and third positions, respectively. By means of geographic reach, SoftBank Group held the top position, followed by NACCO Materials Handling Group and Metso.
