Transylvania Hydrogen Valley

Country
Romania

Transylvania Hydrogen Valley (THV) aims to establish the first integrated green hydrogen ecosystem in Romania, centered in Cluj-Napoca. The project develops a 2.5 MW renewable-powered electrolyzer to supply hydrogen for public transport, district heating, and future industrial use. Partnering with nearby cities, THV will create a regional clean-energy corridor, advancing decarbonization, energy independence, and innovation across Transylvania.
