Our Objectives

Enable More Wind Power

Hydrogen production is flexible and makes wind power production more predictable. More wind power can fit in a national grid, reducing emissions and increasing energy independence.

Multiple Use Cases

Some wind parks will store hydrogen to make electricity later, some will have no grid to connect to (e.g. islands), some will sell hydrogen at a regular schedule. We will develop operation strategies for all these cases, applicable everywhere in Europe and worldwide.

2.5 MW Electrolyser

We will run a prototype 2.5 MW PEM electrolyser (actually, the size of a small closet). This is advanced new technology where hundreds of cells are squeezed into a small volume.

Remote Operation

Many wind parks, like Raggovidda, are difficult to reach, or even offshore. We will build a remote monitoring, prognostics and control system to reduce on-site intervention to a minimum.

Reports and Dissemination

As an innovation project, Haeolus will disseminate its results with multiple reports for the industry (analysis of business case, techno-economics, impact on environment and on energy systems), workshops, a site visit for observers and decision-makers, academic seminars and publications, and presence at industrial fairs.

In addition, many of our deliverables are public, and will be announced and published on these pages as they are completed.
