In recent discussions surrounding the renewable energy sector in australia, a pressing concern has emerged regarding the aluminium industry’s role in the burgeoning solar panel market. At a parliamentary inquiry on August 3, the Australian Aluminium Council’s CEO, Marghanita Johnson, delivered a stark warning: Australia’s aluminium sector risks missing out on significant opportunities tied to the solar panel boom, largely due to its limited engagement in the supply chain.
Aluminium is a critical component of solar panels, constituting over 88 percent of the metal used. Johnson emphasized the substantial demand for this metal, particularly as Australia transitions to renewable energy sources. “For every gigawatt of solar installed, we require 5.5 kilotons of extrusions for the frames, and an additional 13 kilotons for rails and mounting,” she explained. By 2050, projections indicate that the installed solar capacity in Australia will necessitate over 1.5 million tonnes of aluminium extrusions, underscoring the urgent need for local production.
Despite this promising outlook, Johnson pointed out a disconcerting trend: Australian-produced aluminium holds a negligible share in the solar panel supply chain. Currently, more than 70 percent of semi-finished aluminium is imported, with a mere 3 percent of the country’s extrusion capacity allocated to solar applications. This dependency is further exacerbated by the fact that over 90 percent of Australia’s solar panels are sourced from China, highlighting a critical gap in domestic manufacturing capabilities.
To mitigate this issue, Johnson advocated for the establishment of a domestic aluminium recycling and remelting industry. This initiative could create a closed-loop solar value chain that not only strengthens Australia’s industrial resilience but also retains more economic value within the country. By integrating recycling into the production process, Australia could enhance its self-sufficiency and reduce reliance on foreign imports.
The Australian Aluminium Council’s submission to the parliamentary committee highlighted the significant barriers to achieving this vision, notably the influx of imported aluminium priced below international market rates. The council stressed that fostering a competitive environment for local manufacturers would require both government support and strategic investments to boost capacity across Australia’s supply chain.
Moreover, the lack of aluminium recycling facilities poses another hurdle. Following the closure of the last two rolling mills in 2012 and 2014, Australia now exports approximately 95 percent of its aluminium scrap. Johnson pointed out that if the country could recycle just 40 kilotons of scrap domestically—around 10 percent of annual scrap generation—it could directly support over 130 jobs and generate an estimated $300 million in economic value. Such an initiative would lay the groundwork for a circular aluminium economy, capable of processing increasing volumes of aluminium salts from solar photovoltaic systems in the future.
Currently, the industry is exploring small-scale trials for recycling aluminium at select smelters; however, these efforts remain economically unviable without adequate funding to address challenges like transportation costs. Johnson warned that without proactive policy measures, Australia risks falling behind in this critical industry. “If we don’t act soon and create the necessary policy settings to overcome these challenges, we will miss the opportunity to capitalize on our resources and will further disadvantage ourselves in the global market,” she cautioned.
In conclusion, the future of Australia’s aluminium sector in relation to the solar panel industry hinges on strategic investments, enhanced recycling capabilities, and supportive government policies. As the demand for renewable energy continues to grow, the potential for a thriving local aluminium industry remains within reach—if stakeholders can effectively navigate the obstacles that lie ahead.
