China's state-owned oil company, Sinopec, has significantly expanded its floating solar pilot project in Qingdao, aimed at producing green hydrogen from seawater. Despite its strong presence in the petroleum industry, Sinopec's venture into green hydrogen highlights a shift towards decarbonization. The project focuses on innovative solutions such as using seawater for cooling, eliminating the need for additional battery storage, and addressing water-intensive challenges through advanced desalination systems. In contrast, ExxonMobil is promoting 'virtually carbon-free ammonia' by capturing and sequestering carbon emissions at its Texas facility. Sinopec's emphasis on green hydrogen production involves cost-efficient measures like utilizing on-site solar energy, reducing transmission costs, and optimizing power generation efficiency by placing solar panels close to the water. The company's collaboration with the Dalian Institute of Petroleum and Petrochemicals to develop a seawater-to-electrolysis system showcases advancements in sustainable energy production. The expansion to a 23-megawatt floating array at the Qingdao refinery exemplifies Sinopec's dedication to scaling up green hydrogen production and embracing coastal energy solutions for a more sustainable future.
