Swedish Stirling files a patent application

Report this content

Swedish Stirling AB has today filed a patent application for the company's PWR BLOK 400-F product with the European Patent Office (EPO). The ambition of the application is to prevent copying of the unique concept of energy conversion developed by the company.

The Swedish clean tech company Ripasso Energy AB has filed a patent application for the company's PWR BLOK 400-F product with the European Patent Office (EPO). The patent application covers Swedish Stirling AB’s overall system design for generating electricity from process industry residual gases. The claimed features in the patent application are focused on the flexibility and modularity of the present PWR BLOK concept that drives down cost in both investment and operations. The aim of this patent application is to prevent copying of the general PWR BLOK concept of using several Stirling heat engine energy conversion modules built into an intermodal container.

We are first with a new and proprietary technology that creates a whole new market - energy conversion of industrial residual gases. Through a strong patent protection, we ensure that we reap the value of the development work we put in, and makes it costly for major industrial players to copy the concept the day they start to realize how big this market has the potential to become”. Gunnar Larsson, CEO of Swedish Stirling.

Swedish Stirling estimates that the company will have good prospects for defending the application just submitted in case of infringement. The company has previously filed a patent application for PWR BLOK concerning a system for central monitoring and control of the working gas in each Stirling engine.
