The large-scale international project ZAHYR has been launched at the Thracian University in Stara Zagora, which envisages the construction of the first hydrogen valley in Bulgaria.
Paraguay's Green Hydrogen Strategy aims to achieve 1 GW of electrolyzer capacity and 90,000 tonnes per year by 2030, with a focus on decarbonizing the transport sector. Plans include e‑methanol barges, 100 fuel cell electric trucks, fuel-cell buses and up to 10 hydrogen .
The system would need to consist of 1) an electrical hydrogen production device, 2) a hydrogen storage unit, and 3) a device to generate electrical energy from the stored hydrogen, along with the requisite power conversion and control equipment (Figure 1).
California's SamTrans transit agency is pushing ahead with the construction of a permanent hydrogen fueling station at its North Base facility in South San Francisco, following approval of two key contracts with Trillium USA Company, LLC during the board's July 2025 meeting.
This article explores how hydrogen storage technology bridges the gap between intermittent renewables and reliable power supply while creating new economic opportunities. With mountainous terrain limiting traditional grid infrastructure, South Ossetia faces unique energy .
