Bulgaria

A comprehensive hydrogen development initiative in Bulgaria establishing a Hydrogen Centre of Excellence in Stara Zagora and developing hydrogen infrastructure including pipelines and electrolyzer capacity.

A 250-kilometer hydrogen-ready pipeline planned to connect Sofia, Bulgaria to Greece, with potential second phase extension to the Romanian border.

Pilot projects across Bulgaria targeting establishment of 55 MW of electrolyzer capacity by 2025 as an early goal toward the 1.1 GW target by 2030.

Executive arm of the European Union, responsible for proposing legislation, enforcing EU laws, and approving or rejecting member state state‑aid schemes.

Hydrogen industry association

Public–private partnership supporting research and innovation in hydrogen technologies in Europe, succeeding the Fuel Cells and Hydrogen Joint Undertaking.

Hydrogen produced with low or zero carbon emissions, often through methods like electrolysis powered by renewable energy or natural gas with carbon capture.

Vehicles powered by fuel cells converting hydrogen and oxygen into electricity, emitting only water vapor.

A device used to split water into hydrogen and oxygen through electrolysis. Bloom Energy produces solid-oxide electrolyzers.

The Joint Initiative for hydrogen Vehicles across Europe (JIVE) project seeks to deploy new zero-emission hydrogen fuel cell buses and the necessary refueling infrastructure across Europe.

Bulgartransgaz's initiative to retrofit existing natural gas pipeline network to accommodate a 10% hydrogen blend, enabling gradual transition of gas infrastructure.

A hydrogen valley project encompassing Slovenia, Croatia, and the Autonomous Region of Friuli Venezia Giulia in Italy.

Zero-emission bus powered by hydrogen fuel cells, deployed in trial fleets across European cities. Solaris is investing in modular hydrogen platforms.
