By using it to create green hydrogen first. See Australia's National Hydrogen Strategy/Roadmap. Their goal is to become a major global player by 2030. Still a few hurdles to overcome, as usual, but it's much more than just a plan already.
"Yuri will build the plant adjacent to Yara Australia’s world-scale ammonia production facility in the Pilbara region of Western Australia. The plant will produce up to 640 tonnes of renewable hydrogen a year for the facility. Yara Australia is a unit of Norway’s Yara International, the world’s leading crop nutrition company."
That's "only" a 10 megawatt electrolyzer though, they are building much larger.
At almost literally the other side of the world. Shell is building a 200 megawatt electrolyzer in Rotterdam, powered by the wind parks in sea. Problem is that's still only 10% of what they use in their own nearby refinery.
When you put solar panels on your roof in EU it doesn't actually lower the CO2 output. What... yes... and not cause we have funny weather but funny EU laws and regulations. Don't tell anyone lol but to emit CO2 on an industrial basis in EU, you need to pay for CO2 emission rights. When you put solar panels on your roof, power plants have to work less hard, so can buy less CO2 emission rights. The supply of those tradeable rights is fixed, so the demand lowers and thus the prices for those rights lower too, and they end up being sold to others who no longer have to compete with major energy suppliers. Net result is Shell becomes greener, but the total CO2 reduction is zero point zero. It's like a magic trick, making green energy go poof. The largest hydrogen factory of Europe, 4-10 gigawatt, will be build in the north of NL, small harbor town, sucking more energy from the wind parks on sea.
That makes it arguably a bad idea, to use locally produced green energy to create green hydrogen. It's a bit like turning plants into meat while the plants where already food. It costs green electricity to create green hydrogen, while the electricity could be used directly. So we need to import more hydrogen, from places where there's simply more space and sun to create it from green energy sources.
Pretty much the entire west coast of Europe is preparing for green hydrogen from Australia.

With the war in Ukraine forcing the European Union to cut its dependence on fossil fuels from Russia, one renewable technology that it will lean on to help fill the gap is green hydrogen.
