The semiconductor industry, crucial for technological advancement, is under increasing pressure to decarbonize its production processes due to their energy-intensive nature. The demand for semiconductors continues to rise, resulting in a higher energy consumption requirement, mainly derived from fossil fuels like coal and gas. Hydrogen plays a significant role in various semiconductor manufacturing processes, with a shift towards green hydrogen through electrolysis of water powered by renewable energy being seen as a sustainable solution. The potential benefits of transitioning to green hydrogen include reducing carbon emissions, improving supply chain resilience, and offering cost-effective solutions for semiconductor fabs aiming to localize hydrogen production. This shift can also address Scope 1 and Scope 2 emissions while supporting the global goal of limiting temperature rise. Additionally, the semiconductor industry can contribute to the green economy by enabling renewable energy utilization through power semiconductors essential for harnessing, converting, and storing renewable energy efficiently. The industry must adopt a multifaceted approach towards decarbonization, including enhancing energy efficiency, transitioning to renewable sources, and integrating low-carbon technologies. Moreover, decarbonization efforts should extend beyond hydrogen substitution to include circular economy principles, carbon capture technologies, and optimal logistics networks. Companies need to focus on sustainability and research to develop business models that prioritize environmental impact. In conclusion, the integration of green hydrogen and sustainable practices in semiconductor manufacturing is vital for reducing emissions, enhancing efficiency, and aligning with global climate goals. The industry's role in driving technological progress makes it imperative to embrace green solutions for a more sustainable future.
