Green House Capital Update

Dual Fuel now 100% owned

Expanding to barges

Molecular Energies PLC (AIM: MEN), the international energy company, provides an update on Dual Fuel Limited, the hydrogen mobility engineering company, being part of its Green House Capital division.

Dual Fuel Limited ("DFL")

Further to the announcement of the Company on 29 June 2023, Molecular has now completed the acquisition of the remaining 50% in DFL which previously was owned by its engineering and technology partner, G-volution. The transaction is part of a process of simplifying the Green House Capital structure prior to the projected spin off and IPO of that division.

The acquisition price was for a nominal amount with the beneficial relationship with G-volution continuing and now extended on the lines of an exclusive long term commercial engineering and technology provider. All funding of DFL to date has been made by Molecular by way of inter group loan.

Whilst DFL is currently in the midst of engineering a solution to retrofit existing trucks to use a combination of hydrogen and diesel with the lead country Paraguay utilising the Group's own generated hydrogen, DFL is now in parallel moving to engineer a like retrofit solution for barges. Paraguay has the third largest barge fleet in the world providing fertile opportunities for DFL.

DFL is projecting first revenue in 2024 and the Dual Fuel website can be found at www.dualfuellimited.com in which site there is an informative presentation.
