Powerhouse Energy Group Plc

 (the "Company" or "PHE")

European Patent Grant Confirmed

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 it has been notified by the European Patent Office that the Company's European Patent Application No 20751207.0, "Method and Apparatus for the Treatment of Waste Material", will be fully granted on the 11 October 2023.

As stated in the Company's announcement of 13 July 2023, the patent is in relation to protection around the control of the heating of the waste within the Thermal Conversion Chamber ("TCC") over several zones to allow the optimum synthesis gas to be produced. This allows the temperature profile in the TCC to be adjusted to give the optimal syngas composition. The TCC is the main thermal chamber or kiln where the conversion of the waste feedstock to a syngas takes place.

The UK and Europe are expected to become key markets and the granting of patent protection in these territories is therefore an important step for the Company. PHE continues discussions with a number of clients, from a diverse range of industries and sectors, each of which requires a solution for their  waste and are seeking to reduce reliance on virgin fossil fuels.

PHE looks forward to progressing its other patent applications within the UK, Europe and the rest of the world.

Antony Gardner-Hillman, Chairman of PHE, commented:

"I am delighted by this news, which justifies the hard work put into the application, and into the development of the technology preceding that, by the very skilled PHE team. This will be the first patent to be granted to the Company. It provides significant protection for the DMG technology that differentiates PHE from others in the waste-to-energy sector. It is fitting that this patent has been granted while we fit out the Powerhouse Technology Centre in Bridgend. I look forward to keeping the Company's shareholders updated on future developments."
