Swedish Stirling is granted patent for the PWR BLOK
Swedish Stirling has had a patent application – for the solution to use Stirling engines to recover energy from industrial residual gases – approved. The company has intensified its work over the year to strengthen the intellectual property protection for the PWR BLOK technology.
Swedish clean-tech company Swedish Stirling AB has had a patent application, for the company’s PWR BLOK technology, approved. The PWR BLOK unit is a system the company has developed that uses Stirling engines to recover energy from industrial residual gases and heat which is convert into electricity. The solution offers substantial cost savings and a greatly reduced climate impact.
The approved patent covers the overall system design of the PWR BLOK unit, with particular focus on the flexibility and modularity of the concept. Characteristics that reduce both the investment and operating costs of the solution. The patent makes it harder to copy the concept of using several Stirling engines for energy conversion built into a transportable container. The patent application, which was submitted in December 2019, has now been approved for Europe, and is valid until 2039.
“By means of energy recovery and energy conversion with Stirling engine technology, the PWR BLOK can efficiently reduce the industry’s electricity costs, as well as its climate footprint. A strong patent protection of the technology ensures that we’ll reap the rewards of the extensive development work we’ve put in, for a long time", says Dennis Andersson, CEO of Swedish Stirling.
The third generation of the PWR BLOK unit has been in operation since 2021 at Swedish Stirling’s pilot facility at the TC Smelter in South Africa. And in 2022, the company has commenced serial production at its factory in Sibbhult. In parallel with this, the internal work on increasing the intellectual property protection has intensified. Several new applications are being prepared, and the company also thinks that previously submitted patent applications for the PWR BLOK unit will be approved in the coming year.
