Resolution of European Patent Challenge

Powerhouse Energy Group Plc (AIM: PHE), a company pioneering integrated technology that converts non-recyclable waste into low carbon energy, is pleased to announce that the claim originally issued on 6 October 2023 by GetGo Recycling Limited (now called Onunda Ltd) ("Onunda") against its European patent and patent applications has been resolved.

An agreement has been reached to resolve the issues and the Company looks forward to progressing its other patent applications within Europe and the rest of the world.

The agreement ensures that no additional challenge to Powerhouse's patents worldwide will be raised by Onunda or any of its group companies, now or in the future.

Paul Emmitt, CEO of PHE commented:

"This is a major step forward for Powerhouse and I am pleased that this matter has been resolved.  The whole process has been extremely time consuming and a significant diversion for the team over the last seven months. The closure of this matter now allows us to return to our main goals of progressing our R&D activities, the FTU and our project pipeline which we believe will provide value to our shareholders."
