Ripasso Energy files patent applications

Ripasso Energy announces that as of today, several patent applications concerning the hybridization aspect of Ripasso’s Stirling engine have been filed to The European Patent Office (EPO).

In a press release on February 14, the intention to file the applications in the first quarter of 2017 was made public. This has now been carried out and a total of three patent applications have been filed, all relating to the hybridization functionality in the Stirling engine. The three innovations that have been submitted for patent protection are:

1. A new type of enclosure for the Stirling engine heat exchanger which, based on low cost materials, enables the ability to combine solar radiation and hot gases from the combustion of liquid and gaseous fuels.
    
2. A new type of burner that is optimized to transfer more heat to the engine's heat exchanger, than has been possible with previously known burner solutions.
    
3. An optimized design of the engine heat exchanger which enables it to receive both radiated heat and heat from hot combustion gases, with high efficiency.

“The extensive protection offered by these three applications will most certainly ensure control of the unique aspects of our product in our hands”, says Gunnar Larsson, CEO and founder of Ripasso Energy. “The patents, combined with our exclusive license from Kockums, means that it will be both expensive and difficult to rival the performance demonstrated by our Stirling engine”. 

Ripasso Energy has constructed a Stirling engine, intended to be used in combination with a parabolic mirror. Together, they form a highly efficient way to convert the rays of the sun into electricity. Further, Ripasso Energy has developed a combustion based addition to the engine, intended as a complement when the sun is not available. This hybridization allows for continuous generation of electricity in a single product, regardless of lighting or weather conditions. Practically any fluid or gaseous fuel can be used and as the Stirling engine is solely heated externally, different kinds of fluids can be phased in or out, depending on their availability. This provides a unique degree of freedom which, combined with a world leading solar-to-grid conversion rate, has resulted in a cost-efficient product, well equipped to face present and future needs of available and clean energy. The output of each unit is 33 kW and as it is completely autonomous, it allows for the power generating capacity to be distributed, rather than centralized. Consequently, the need of a transmission grid is greatly reduced, which in certain cases can be a prohibitively expensive factor. Remote or off-the-grid locations are interesting potential markets for Ripasso Energy, as the always-on, modular Stirling engine can guarantee the availability of power.
