The conference 'Green Hydrogen as a Guide to Energy Transition' held in Belgrade emphasized the significance of green hydrogen as a driver for decarbonisation, energy security, and technological advancement. The European Union, aiming to become a climate-neutral continent by 2050, views green hydrogen as a pivotal element in achieving this goal. The EU Hydrogen Strategy, part of the European Green Deal, focuses on accelerating the deployment of renewable hydrogen technologies and establishing a competitive hydrogen market through extensive research and development. The Energy Development Strategy in Serbia has now explicitly incorporated hydrogen in its energy transition plans, aligning with EU trends and regulations. The EU's vision involves repurposing a substantial portion of the natural gas network for hydrogen by 2030, a move expected to have a similar impact in Serbia. Green hydrogen, produced using renewable electricity, offers a zero-emission alternative to traditional fossil fuels and is a key component in the EU's strategy for energy transition and sustainable development. Stakeholders at the conference exchanged insights on the current status and future challenges of hydrogen production and distribution in the EU and Serbia. The future plan includes a larger-scale conference to delve deeper into these topics. The goal is for renewable hydrogen to account for around 10% of the EU's energy needs by 2050, significantly reducing carbon emissions in industrial processes and the transport sector. Overall, the sentiment towards green hydrogen in the article is positive, highlighting its pivotal role in shaping a sustainable energy future.
