Green hydrogen tenders
Hydrogen procurement covers the whole value chain, and public buyers appear at most points along it. Governments and energy agencies tender national hydrogen strategies, market studies and certification schemes for low-carbon hydrogen; regions and ports commission hub and valley feasibility studies; transport authorities buy hydrogen buses, refuelling stations and fuel supply; and utilities and industrial clusters tender electrolysers, pipelines and storage.
Notices are technical and often large. Equipment tenders specify electrolyser technology, capacity, efficiency and lifetime guarantees; supply tenders specify purity, delivery and the carbon intensity of production; study tenders ask for techno-economic modelling and offtake analysis. In Europe, prequalification stages are common for larger projects, and notices may reference the rules that define renewable hydrogen.
This page lists open tenders that mention hydrogen or electrolysers. It serves hydrogen developers, equipment suppliers, engineering firms and energy transition consultancies, and it is a useful early signal: a feasibility study tendered today is often the first step towards the equipment and supply contracts that follow a few years later.
16 open tenders match this topic today, across 4 countries on the first page. 10 of those shown close within 30 days. Recently closed notices are listed after the open ones. Deadlines come from the source notice; confirm against the official document before you submit.
