Powerhouse Energy Group PLC (AIM:PHE, ETR:BT81) said emergency access to its site at the Protos Energy park has now been completed, while service ducting has been installed.
The ultimate construction of the waste-to-hydrogen facility remains subject to numerous engineering steps and raising the necessary finance for its construction, Powerhouse added.
Keith Riley, interim chairman and acting chief executive, said: "These two items form an important part of the infrastructure required to enable the Protos Plastics to Hydrogen facility to proceed.
“Emergency access is required to facilitate the installation of the electrical substation, which will both provide power to the site and allow it to be exported from the site when the plant runs in generation mode.
“The service ducting will enable the cabling and other services to be run into the site below the ground.
"We continue to work closely with [partner] Peel to progress the Protos Plastics to Hydrogen project, with further developments anticipated in and around the site shortly."
