Adelaide’s Bolivar Wastewater Treatment Plant, one of South Australia’s most significant recyclers of wastewater, will supply a massive irrigation scheme after the Australian Federal Government confirmed funding for the project.

Costing AU$156mn and taking 18 months to build once officially signed off, the sustainable water development will create upwards of 3,700 jobs and add $500mn to South Australia’s economy every year. 

Initial extra output from Bolivar is predicted to be 12bn litres of water a year, or 12 gigalitres.

This represents a 60% increase in output from the site at a time when concerns have been raised about Australia’s ability to handle predicted hikes in urban populations. The extra capacity will significantly boost the area’s ability to farm commercial crops in a sustainable manner.  

Once at full capacity the site, which draws water from the Gawler River, will produce 20bn extra litres of recycled water a year.

South Australia Premier Jay Wetherill said: “This scheme is about supporting our State’s primary production industry and Adelaide’s northern suburbs by creating jobs and diversifying the local economy.

“The Federal Government has made a valuable contribution to an initiative which will provide economic growth and stability in the Northern Adelaide Plains.

“The scheme’s focus is helping South Australia to be competitive in the export market by transforming the region into the national leader in intensive, high-tech food production, as well as drive employment growth and attract new skills and talent into the state.”

Trafigura and Yara International explore clean ammonia usage

Commodity trading company Trafigura and Yara International sign MoU to explore developing ammonia as a clean fuel in shipping

Independent commodity trading company Trafigura and Yara International have signed an MoU to explore developing ammonia as a clean fuel in shipping and ammonia fuel infrastructure.

Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050. 

How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.

Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:

  • The supply of clean ammonia by Yara to Trafigura Group companies
  • Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
  • Development of new clean ammonia assets including marine fuel infrastructure and market opportunities

Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.  

There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.

Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.

Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.

Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.

It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
