Certification for UK company converting waste plastics to hydrogen
A UK technology company pioneering hydrogen production from waste plastic and used tyres has received independent technical assurance certification for its waste to power and waste to hydrogen technology processes.
PowerHouse Energy (PHE) Group has developed a process technology, known as DMG®, to convert waste plastic, end-of-life tyres and other wastes into EcoSynthesis gas, which can be used to create valuable products such as chemical precursors, hydrogen, electricity and other industrial products. The DMG® process can generate in excess of one tonne of road-fuel quality hydrogen and more than 28 megawatt hours of exportable electricity per day.
The independent review of PHE’s technology was carried out by DNV GL, a global quality assurance and risk management company. DNV GL has issued a ‘Statement of Feasibility’ to the DMG® technology, meaning its Technology Assessment found no prohibitive obstacles to the development of the technology.
As part of the certification process, PHE undertook an extensive engineering, safety and risk management programme over several months. The programme involved a robust and rigorous review of the engineering design, test data, process modelling and the equipment engineering design required for the commercial application of the DMG® technology.
The DNV GL ‘Statement of Feasibility’ states that ‘the PowerHouse Energy Group’s DMG® waste-to-energy technology can convert 25 tonnes per day of feedstock comprising high calorific value waste materials.’
With regard to the outputs of the DMG® technology, it adds: ‘The produced energy-rich syngas can be combusted to produce power for distributed electrical generation. The DMG® technology allows for integrating a process for the co-production of high purity hydrogen (one tonne per day) from a proportion of the syngas in addition to generating power.’
The Statement of Feasibility also confirms that the DMG® technology eliminated waste with high levels of energy recovery, produces electricity for distribution and has the ability to co-produce high purity hydrogen with electrical power.
PHE has identified seven sites, including one at Ellesmere Port in Cheshire, where application-specific engineering activities are taking place, with each site comprising different specific waste streams that will be processed by a DMG® technology ‘research demonstrator’.
Commenting on the news, David Ryan, PHE’s Engineering Director, said: “Gaining this Statement of Feasibility provides us with a key foundation in the engineering and risk mitigation programme, giving us great confidence in the scale up and roll out of the technology. Furthermore, it provides our partners in the waste management industry with a key element of the independent technical assurance needed to finalise site application-specific commercial agreements to utilise the DMG® technology to reduce the volumes of waste plastics sent to landfill.
“Our expectations are that, with our planned engineering and risk management in place, the commercial operation of our DMG® technology will exceed one tonne of hydrogen production and generate in excess of two megawatts of electricity per DMG® unit, and we should achieve full certification against the DNV GL Technology Qualification process at our first site”.
Keith Allaun, the company’s CEO, added: “We sought this Technology Assessment of our engineering design by one of the world’s most highly respected evaluators of new technologies. DNV GL confirms both our technology design and the rigour of our engineering approach. Our team has worked relentlessly over the last 18 months to get the DMG® technology to its existing commercialisation phase.
“This independent assessment of our proprietary DMG® Technology adds further credibility to the considerable scope that exists for its commercial application, in the many sectors [involving] efficient and responsible use of non-recyclable and waste plastics, end-of-life tyres, and the creation of clean energy”.
