Global Energy Ventures Ltd has provided an update on its 2.8 GW green hydrogen export project on the Tiwi Islands, Northern Territory, Australia (the Tiwi Hydrogen Project). 

GEV’s Executive Director and Chief Development Officer, Garry Triglavcanin commented: “The Company is delighted with the engagement of Darwin-based EcOz to prepare the environmental Referral submission on behalf of GEV. EcOz has extensive experience in Referral submissions for renewable energy projects both in the NT and the Tiwi Islands. The Referral submission is an important step forward as the environmental process is likely to drive the project schedule. There are a number of key environmental studies that can only be conducted during the current wet season.

Further to our previously announced MOU with ILF Consulting Engineers in Germany (ILF), GEV is delighted to commence work with ILF to assist with solar generation and transmission engineering work for the Tiwi Hydrogen Project. Additional engineering will also focus on water desalination requirements to supply pure water to the electrolysis plant.” 

LOW ENVIRONMENTAL FOOTPRINT GEV continues to pursue a low environmental footprint for the Tiwi Hydrogen Project, with the proposed solar site planned to be constructed on existing plantation land, and the hydrogen production, compression and loading facilities proposed to be built on the existing industrial precinct / existing port area. For the Referral submission to reflect this view, consultants have now been engaged to undertake engineering studies for the key components, being the transmission line route and water desalination. 
The purpose of the Referral submission is to provide sufficient information to the NT Environment Protection Authority (NT EPA) so that a decision can be made on the level of assessment required for the Tiwi Hydrogen Project. GEV expects to lodge its Referral submission in the first half of 2022. 

ENGINEERING STUDIES SUPPORTING THE REFERRAL SUBMISSION The engagements by GEV of Jacobs Group (Australia) Pty Ltd (water desalination) and ILF (transmission line) are especially important at this time, as they address two key environmental impact areas of the Tiwi Hydrogen Project, being the brine discharge from the proposed desalination plant; and the environmental impact of clearing the ~30-kilometre transmission line corridor. The engineering study to be undertaken by Jacobs will include both near and far-field modelling of the brine discharge. 
These studies will assist GEV in demonstrating to both the NT EPA and the Tiwi people that the brine discharge and transmission line corridor maintains a low environmental impact, being a material advantage of the Project. GEV will continue to provide updates as further engagements are made. 

NEXT STEPS The Company continues to work closely with the Tiwi Land Council, Munupi Landowners and the Tiwi Plantation Corporation for land access requirements to support the project, including the solar site and transmission corridor. The Northern Territory Government has also appointed a Case Manager to the Tiwi Hydrogen Project to support GEV’s interface and requirements with relevant government agencies. 
GEV will advance discussions with suitable groups to support the detailed engineering of solar generation and electrolysis for the production of green hydrogen. Appointments will be made during the March and June quarters to commence detailed engineering, including experienced renewable project resources, to support the target of financial close (of the initial phase) by mid-2023. 

The Company will also get underway with preliminary marketing activities of green hydrogen from the Tiwi Hydrogen Project in the March quarter, with a number of strategies to identify relevant parties for potential offtake in the markets of Singapore, Japan, Korea and Indonesia.
