Abandonment of the green hydrogen megaproject in South Africa – pv magazine International

Kallis Energy Investments has confirmed that it will shelve its proposal to build a 6GW renewable hydrogen project in Moolawatana, South Australia, due to water supply issues.

Terry Kallis, founder of Kallis Energy Investments, confirmed over the weekend that his company 6 GW Moolawatana Green Hydrogen Project will not progress after an assessment of its water supply.

“This assessment, announced in the initial project announcement, determined that the environmental and permitting risks associated with water supply and desalination were unacceptable. Therefore, the project was stopped,” Kallis said on LinkedIn.

The Moolawatana Green Hydrogen Project had proposed to build a combined solar and wind farm, each with up to 3 GW of capacity, which would only power electrolysers on 100,000 hectares just east of the northern Flinders Ranges. Kallis Energy also planned to include a desalination plant on the site and, as noted by Kallis, had already flagged water as a potential obstacle, which later proved insurmountable at the pre-feasibility stage.

“Not all projects work and it’s important that developers identify fatal flaws as early as possible in the project schedule and communicate this to stakeholders,” Kallis said.

Kallis said he looked at other locations with better water prospects, but couldn’t find anything suitable for the massive multi-gigawatt he was looking for.

The shutdown of the Moolawatana project will not impact the Murchison Renewable Hydrogen project in Western Australia, added Kallis, of which he is a co-founder.

The Murchison Proposal involves up to 5.2 GW of combined onshore wind and solar power and aims to produce two million tonnes per year of green ammonia for export. The proposed site for this project is at Northampton, approximately 20 kilometers north of Kalbarri on the mid-coast of WA.

Kallis said the Murchison Renewable Hydrogen project is “full steam ahead”.

The company founder did not comment on two other major projects in which Kallis Energy is involved, the 2 GW Star of the South offshore wind farm and the Starfish Hill wind farm in South Africa, but these projects are likely not either. more affected by the news from Moolawatana.
