Haeolus in a nutshell

The Project in Brief

Haeolus is a EU project that proposes a new-generation electrolyser integrated within a state-of-the-art wind farm in a remote area with access to a weak power grid.
Haeolus will demonstrate multiple control systems, to answer the specific challenges of the three main modes of operation identified by the International Energy Agency:

  • Electricity storage
  • Mini-grid
  • Fuel production

For each of these modes, new operating strategies will be developed, optimizing operation concerning uncertain weather and power-price forecastsbut also constraints of the specific operating mode.
In addition, Haeolus’ demonstration shall be completely remotely controlled and monitored, due to the remoteness of the selected location and its difficult accessibility in winter; this is a characteristic of many wind farms.

The Objectives

More Wind Power

More Wind Power

Haeolus shall demonstrate several control strategies allowing wind-hydrogen integration, reducing the unpredictability of power produced by a wind farm, and thereby enabling much higher rates of renewable energy penetration in the European grid.

Use Cases

Use Cases

Haeolus will develop and test control strategies for each mode of operation for wind-hydrogen systems: energy storage, mini-grid and fuel production. The results will be relevant to many wind farms across Europe and worldwide.

2,5 MW Electrolyser

2,5 MW Electrolyser

Haeolus will demonstrate for the first time a 2,5 MW PEM electrolyser with a single-cell stack: a unique PEM cell stack, developed by Hydrogenics, will contain up to 420 cells. We will analyse the data from this electrolyser and benchmark against the results from other EU projects.

Remote Operation

Remote Operation

Very often, wind parks are in inaccessible regions—as is the case for our site of Raggovidda, Norway. Haeolus will demonstrate the ability to run a wind-hydrogen system in a remotely controlled setup, with only occasional on-site maintenance.

Dissemination

Dissemination

Haeolus will deliver public reports with analyses of business-case, techno-economical factors, environmental impact, impact on the European energy system, and a technology roadmap towards the MAWP 2013 targets.

Protocols for demonstration of fuel-production strategy

Tecnalia propose a deliverable that defines the suite of test protocols that will be used to assess the demonstration performance of the HAELOLUS system when configured for operations in the fuel-production use case. Fuel-production use case covers the option of the combination of the wind-hydrogen systems that maximise the
production of hydrogen by the electrolyser feed by the energy coming from the wind farm. These protocols shall ensure that all relevant aspects of that control algorithms shall be tested during demonstration.

Control system for fuel-production use case

Colleagues from UniSannio contributed to a new public deliverable for the HAEOLUS project.

In this report a Model Predictive Control approach is designed.
In the fuel-production control algorithm, hydrogen production objectives are two-fold: to deliver hydrogen as a fuel to (road) vehicles and to provide a demand and generation management solution for energy supply modulation. The priority comes first with the first objective, and then any excess of stored hydrogen will be re-electrified through fuel cell in meeting electrical references.

Haeolus’ Second Summer School

The second summer school for undergraduate and graduate students, out of three to be held by the Haeolus project, was held online on 30 June and 1 July 2021. The presentations are included below.

Haeolus Demonstration Started

The Haeolus project is very excited to announce that finally, on the 15th of June 2021, KES, in collaboration with Hydrogenics and Varanger Kraft, started the first of a suite of tests developed by Tecnalia for the energy-storage control strategy. With this, the 2.5 year long demonstration phase is officially started, after several delays due to the Covid-19 pandemic and other factors. The tests were run from Benevento in Italy to demonstrate remote operation, which is a key feature of Haeolus.

Haeolus Installation Finally Starting!

After a 2020 with so many delays due to the Covid-19 pandemic, we are happy to report that the hydrogen system (both electrolyser, fuel cell, converters etc.) is on the way to Berlevåg, and is scheduled to arrive on 5 May 2021.

Personnel from Hydrogenics just arrived on site, after a week of quarantine at Oslo airport. From tomorrow, you may peek at the operations from the webcam in Berlevåg’s harbour.
