Phase change materials: technology leaders?

Phase change materials are an emerging materials class, which can store and release heat (or coldness) as they change beween solid and liquid phases. Our recent research finds they can improve the efficiency of cold storage by c20%, at attractive economics, which is superior to any other battery.

The aim of this data file is to identify the technology leaders in phase change materials, by quantifying 21,000 patents filed into the topic, and compiling a list of 5,800 patents by over 125 companies in the space.

The leading patent filers are ranked in the Leaders tab, and can be filtered by sub-sectors (shown above are companies in the refrigeration and air conditioning industry). All the raw data across 5,800 patents follow in the final tab.
