Under the auspices of the International Energy Agency’s Hydrogen Implementing Agreement, a working group has been evaluating and comparing experiences of green hydrogen production with wind energy.

This paper presents an overview of Task 24 –Wind Energy and Hydrogen Integration– which has been underway since April 2007. There are currently 21 members from 9 countries working in four subtasks which undertake the following activities:

Subtask A: State of the Art;
Subtask B: Needed improvements & system integration. Technology development of
main equipment and system integration concepts;
Subtask C: Business concept development;
Subtask D: Applications (with emphasis on wind energy management).

The two main objectives are:

• To explore in detail all possible issues (technical, economic, social, environmental, market and legal) related to hydrogen production using electrolysis with wind energy.
• To analyze possible applications for hydrogen produced by electrolysis using wind energy, with special emphasis on full wind & hydrogen integration by means of hydrogen storage and electrical conversion that balances the original wind energy production, allowing an approach to demand that closes the gap between conventional energies.

In this paper results from the first phase will be presented, with more than 10 world wide wind/hydrogen projects analyzed.
