An Australian company has today (December 18) launched plans for a AUD $425m ($285.6m) large-scale waste-to-hydrogen progressing facility in South Australia.

Greenhill Energy has said it intends to build the country’s “first” fully integrated facility to convert landfill waste and sustainable biomass into fertilisers, synthetic fuels and low-cost clean hydrogen.

With hopes for the facility to divert up to 200,000 tonnes of waste from landfill within five years, CO2 produced from the process is planned to be used in the manufacture of over 100,000 tonnes of urea fertilisers.

In the first phase of the project, which Greenhill hopes to construct in 2025, a single gasifier will be installed – allowing the processing of up to 60,000 tonnes of biomass or waste per year for syngas production and use in a combined cycle gas turbine (CCGT).

The second phase plans to install a second gasifier and integrate hydrogen-to-urea manufacturing capacity. Gas separation facilities and post syngas clean-up would provide gas streams of hydrogen and carbon dioxide.

The company, following “positive” trials and R&D, has secured 20 hectares of land at Tailem Bend in Murraylands for the flagship project – the Riverbend Energy Hub.

Nicholas Mumford, Executive Managing Director at Greenhill Energy, said the company had also been granted state government crown sponsorship across the project.

Mumford said five years of research led the company to learn more about waste-to-hydrogen technologies, “which are in successful application across many European countries.”

He continued, “We also added a twist of Australian innovation to integrate energy inputs and outputs into a novel, closed ecosystem with diverse products.”

Having signed several MoUs for waste feedstock and product off-take, the company hopes the inaugural project will become a blueprint for other sites “across Australia and internationally.”
