In an unassuming industrial park in Tonsley, south of Adelaide, the Australian Gas Infrastructure Group (AGIG) is spearheading the nation's largest gas decarbonisation project, Hydrogen Park SA. With a $4.9m contribution from the State Government, the $15m prototype plant produces hydrogen blended with natural gas for around 4000 homes and businesses in metropolitan Adelaide. AGIG's Chief Executive, Craig de Laine, envisions a future where hydrogen integration leads to a renewable energy system, aiding in the push toward net zero by 2050. The project includes plans to raise the hydrogen blend to 100% and expand to Gladstone with a renewable hydrogen blend by 2024. AGIG's low-carbon vision aims for at least 10% renewable gas by 2030, transitioning to 100% renewable gas by 2040-2050. Despite debates on the effectiveness and cost of hydrogen compared to green electricity, AGIG continues to pilot projects nationwide, including HyHome in Melbourne, showcasing a 100% hydrogen home. The Federal Government's support and investments in hydrogen production further underline the commitment to renewable gas in the energy transition.
