AB Vilnius heat networks (VŠT) in Vilnius, Lithuania, has received a positive Environmental Impact Assessment (EIA) conclusion for their green hydrogen production project aimed at sustainable public transport. The project, utilizing renewable energy sources (RES), will produce green hydrogen to replace 16 diesel buses, saving 1414 tons of CO2 emissions annually. This initiative aligns with the city's goal of becoming climate-neutral by 2030. The green hydrogen plant will not only supply Vilnius public transport but also provide access to the public. It will leverage waste heat for district heating water preparation, maximizing infrastructure efficiency. The company plans to use the wastewater generated during hydrogen production and collect waste heat to produce energy as sustainably as possible.
