According to the video, it was funded by the EU in hopes of mass deployment to reduce energy waste in supermarkets (no need to keep an entire open drink case chilled if customers can cool their drinks on their way out the door), and they're planning to license it worldwide for a reasonable price.
Either the license will be cheap, in which case nobody will get rich from it, or it will be expensive, in which case no product companies will buy the license and nobody will get rich from it. Basically, nobody will get rich from it.
In 20 years, however, when the patent expires, it will be old tech, so probably only a single company will dare to invest research into a new product using this now-old tech. This company will know what happened last time: If the license was expensive, they will try to be cheap to avoid the same mistake twice, and it will be good tech, sold cheaply, which will probably sell well and make them a lot of money. If the license was cheap, they will want to avoid the stigma of the glut of low-quality goods the cheap license allowed back in the day, so the new product will be high-end (probably renamed and re-purposed to another field), which means a high margin, which has a good chance of making them a lot of money.
Basically, some company will probably make a lot of money.
