The South Australian Government has launched a bid to host COP31, the United Nations climate change conference, with Whyalla’s developing hydrogen industry among the projects being highlighted as part of the state’s climate and energy credentials.

The government says hosting COP31 could generate an estimated $511.6 million in economic benefits for South Australia through increased tourism, trade, investment and international exposure.

Whyalla features prominently in the state's renewable-energy ambitions. The government has pointed to the world’s largest hydrogen electrolyser and power station, currently under construction in Whyalla, as one of the major projects demonstrating South Australia’s role in the development of new energy technologies.

The proposed hydrogen development forms part of the broader industrial transformation planned for Whyalla. The city has traditionally been strongly associated with steelmaking, but governments and industry are increasingly looking at renewable energy and hydrogen as potential components of its future industrial economy.

South Australia is also promoting its broader renewable-energy performance as part of the COP31 proposal. According to the state government, 75 per cent of the state’s energy currently comes from renewable sources, with an ambitious target of reaching 100 per cent renewable energy by 2027.

The government argues that these developments position South Australia as a strong candidate to showcase Australian climate innovation to an international audience.

For Whyalla, international attention connected to COP31 could potentially provide greater visibility for the city's energy and industrial projects. The hydrogen development is particularly significant because it is intended to support the transition of the region's industrial economy while increasing the use of renewable energy.

The proposal also comes as Whyalla continues to undergo significant industrial and economic change. The city's future has been closely linked to decisions about steel production, new energy technologies and investment in major infrastructure.

If South Australia's bid is successful, the conference could bring international delegates, businesses, researchers and government representatives to the state. The government says this would provide opportunities for tourism, trade and investment while showcasing South Australia's renewable-energy capabilities.

The COP31 proposal is part of a broader Australian effort to secure the international climate conference. South Australia says its renewable-energy record and major projects, including those being developed in Whyalla, make the state a natural choice to host the event.
