Power grids in most developed countries traditionally operate under centralized models of energy generation and distribution. However, the shift towards decarbonization and the incorporation of renewable sources like wind, solar, and green hydrogen is altering this landscape. The need for decentralized energy systems is growing to manage the variability in energy demand, especially with the inclusion of sources like electric vehicles. Modular automation solutions are being recognized as vital in supporting this transition. Standardization and interchangeable modules reduce complexities and costs in manufacturing and assembly. ABB has introduced a groundbreaking modular enabled process automation solution, emphasizing the importance of standardization in the industry. Finland stands out for its commitment to green hydrogen and Power-to-X technologies, utilizing its abundant resources and clean electricity system to drive carbon-neutral goals. The country aims to produce a significant portion of the EU's green hydrogen by 2030, supported by its expertise in various industries related to the hydrogen economy. Collaboration among technology vendors and government entities is highlighted as essential in advancing efficient technologies for hydrogen production. As the world moves towards low-emission hydrogen production through electrolysis, standardized approaches will play a crucial role in scaling up electrolyzer capacity. Finland's dedication to clean hydrogen production and the development of modular automation solutions position the country competitively in the global energy transition.
