The idea for an LNG training facility was conceived at UWA in 2014 as part of its successful bid for an Australian Research Council Industrial Transformation Training Centre. Further funding was secured from National Resources Energy Australia (NERA) in 2018 to develop a living laboratory for technology demonstration.

Over time this developed into a broader training and LNG research testing facility with a 10 tonne per day plant. A major milestone was the commitment by the WA State Government to provide the grant of land at Kwinana and $10 million in funding over ten years. At this point the concept was known as the LNG Futures Facility.

In 2020 the concept developed further to address the increasing challenge of transitioning the energy industry to net-zero emissions with the addition of a green hydrogen plant, before KETH as its latest iteration was formally established in 2021.
