I am of the same opinion, the disappointing attitude the company has towards the OHD project:
1) bear in mind as per what I posted earlier, snippets of feedback from shareholders/forum posters of last years AGM, re: "As I had the impression GK understands the Company's and Shareholder sentiment, that the projects timeline needs fast tracking as much as possible, as GK implied, urgency is required on OHD just quietly." - end of Oct 17

2) this was from an announcement released 26th Oct 17 - one day prior to the AGM, and only 6 months ago.

3) OHD expert engaged, to do what? Achievements to date?
Trench’s job made easy: As per the announcement of his appointment, 11^th August 17 https://www.asx.com.au/asxpdf/20170811/pdf/43lb8hslkvjrvz.pdf aspects of his job were supervising the sourcing of feedstocks
a) coal: an announcement released 18^th August 16 GPP had already determined the licence areas for the most suitable, accessible and geologically well defined area of the inferred lignite deposit that contains sufficient volume to supply foreseeable needs for the company’s CTL feedstock requirements – almost 12 months before his appointment.

b) water/electricity/site: Discussions with the preferred infrastructure provider in the Latrobe Valley regarding the supply of coal, electricity, and water at one site where the OHD plant is proposed to be constructed were progressing well with a final decision to be made shortly. Announcement released 24^th May 17 – 2 ½ months before his appointment.

In the "fullness of time" Trench and GPP envisaged he would move into a full time engagement in a Chief Operations Officer role and allegedly, he was introduced to last years AGM as such, but there has been no announcement to quantify this.

An estimated $4 - 5 million of shareholders funds has been poured into the OHD project, but is history repeating and will this be mothballed like every other project since listing has been, whilst the company (basically lead by the same management) goes off chasing the next big thing. Can almost sense that hitting Lithium at Turesi will either make or break GPP.

It is a bit of a concern that the government is willing to provide funding for a large project in the Latrobe Valley region, but the last two attempts by GPP to get government grants for the OHD project has been unsuccessful.
Would the fact that Thermaquatica's PDU is having technical difficulties have a bearing on the grant result?

All the above is IMO only
