The pace of innovation for patents in the technology fields of energy transition and decarbonisation has increased sharply in recent years.

Our recent analysis of global patent trends in this technology field (Figure 1) reveals a sharp increase in the number of patent applications, from under 16,000 filed patent families in 2006 to a staggering 58,011 in 2024. The number of granted patents has followed the same trend, with 31,062 patents granted in 2024. This strongly underscores the growing momentum and commercial demand within this technology sector, showing that patenting is considered a key tool to secure competitive advantages and drive long-term growth.

China stands out as the clear dominant player, with almost 222,000 national patent applications since 2006, followed by the USA, Japan, South Korea and the European Patent Office (Figure 2). In comparison, national patent application filings in Denmark (2056), Norway (765) and Sweden (211) were relatively modest during this period.

Among the key technology terms driving growth in this trend are hydrogen production, fuel cell development, carbon dioxide capture, and electrolyte membranes.

This data highlights a clear global shift toward sustainable technologies, improved resource utilisation, and the development of advanced solutions that support the energy transition.

For Norwegian, Swedish, and Danish companies, staying leaders in innovation means combining fresh ideas with smart patenting to protect their inventions. Patents are more than just paperwork—they help keep companies competitive, safeguard technology, and open global markets.

While not patenting is a valid choice, the growing number of patents by others means companies need clear strategies to avoid costly mistakes, especially when exploring international business.
