Brown Coal is Dead?, page-10

I was told by IK at the last agm that chtd is proven as far as the people at Exergen are concerned. Probably because the 700m deep autoclave pilot plant at beaconsfield was such a success. I think perhaps Exergen are waiting on the downstream process techs and companies to get their projects up and running, like DICE and KHI's hydrogen.

Csiro have big wraps on the chtd tech. The high efficiency of the tech is it's strength, utilising gravity to generate the high heat required for the process.
