The HANNOVER MESSE 2023, the world's most important event for industrial technology, focuses on digitalization and sustainability because they are the key to transforming business and industry. They enable digitalized, climate-neutral, and sustainable value creation. Exhibitors at HANNOVER MESSE have combined digitalization, artificial intelligence, automation, and sustainable energy concepts to develop solutions to the global challenges of climate change. Companies from mechanical and electrical engineering as well as the software and IT sectors demonstrate how digitalization and automation link together factories to produce more efficiently and use fewer resources. Companies from the energy industry show how to generate and transmit energy efficiently and sustainably; how to produce and use hydrogen for industrial production; and how to distribute wind and solar power intelligently. These technologies offer considerable potential, especially for energy-intensive manufacturing companies.
