Africa's first wind hydrogen system launched
The first African initiative to make hydrogen from water using green energy has been successfully installed in Morocco.
The Pure Energy® Centre, the UK pure® fuel, renewable energy and energy storage company in collaboration with Sahara Wind Inc. and Al Akhawayn University in Morocco announce the completion of Africa’s First Wind Hydrogen System. The hydrogen system has been installed to enable the storage of excess wind energy. The installed system demonstrates that the intermittency of the wind and excess production can be resolved.
Sahara Wind Inc. of Morocco, has coordinated the installation of a wind farm consisting of three wind turbines at Al Akhawayn University, one Moroccan’s top University. The installation of the wind turbines meant that green energy could be used around the University campus.
However, it was found that there were times where there would be excess energy produced from the wind turbines. A good example of such excess is when the wind turbines would generate power at night. In this case, there would be very little load demand on the campus, hence the wind turbine needed to be shut down. This is why the Pure Energy® Centre was commissioned to design and install a hydrogen energy storage system. The stored energy could then be re-used at a later stage when no wind generation was available through different hydrogen applications.
The Pure Energy® Centre, an expert company in renewable and energy storage technologies, installed the hydrogen system. This consisted of a hydrogen electrolyser, a hydrogen store and a fuel cell. The hydrogen electrolyser is used to produce hydrogen from water. The electrolyser split water into its two main molecules. It uses electricity to break H2O (water) into H2 (hydrogen) and O2 (oxygen) molecules. The H2 gas is stored into a hydrogen tank while the O2 is vented to the atmosphere. In other installations, the O2 is also stored so that it can be used. Usage of the O2 gas is found in many industries such as welding, hospitals and others.
This cutting-edge project, which has been driven by Sahara Wind Inc. with financial support from the North Atlantic Treaty Organisation NATO under its Science for Peace and Security frameworks. As a result, AUl and Pure Energy® Centre, will see many Moroccan engineers accessing state-of-the art energy storage technologies. Elizabeth Johnson, Business Development Manager of the Pure Energy® Centre said: “We are very pleased to have been involved in Africa’s first wind hydrogen system. We are especially pleased to have installed latest hydrogen technologies which will be used for teaching and training tomorrow’s Africa top engineers. We feel very proud of the hydrogen system which operates at the back of wind power, fully demonstrating our commitment to renewables.”
Khalid Benhamou, from Sahara Wind Inc. said: “Renewables have one major issue in that they are intermittent. We have identified that we can reduce this issue by storing excess energy produced from renewables as hydrogen and thereafter reuse the hydrogen in a fuel cell for power generation. We feel that coupling wind and hydrogen will play an important role in Africa’s future through a variety of applications involving the continent’s main industries. The applications are indeed numerous: They range from powering telecommunications networks and green mobility (to be developed in partnership with local telecom and automotive industries) and extend to water utilities and mine processing industries. The latter would use hydrogen and other electrolysis byproducts such as chlorine as feedstock. We are therefore pleased that this project is a success and look forward to use green hydrogen for many applications”.
Khalid Loudiyi, from Al Akhawayn University added: “The wind and hydrogen systems will be used for training, teaching and research. Our aim is to strengthen our research portfolio and to develop a number of hydrogen applications such as fuel cell vehicles, cooking and even heating as Al Akhawayn University has been built at a 1600 meter height and winters are cold here. We are highly pleased that the wind hydrogen systems installation has been successful and look forward to a bright future for green energy and storage technologies in Morocco.”
Why hydrogen energy storage?
There are two main reasons the world’s need energy storage technologies. These are that energy storage can reduce (a) the impact of renewable intermittency and (b) resolve the issue with excess green power. When one installs a wind turbine, this turbine will only operate when there is wind. So when there is no wind, we would need to switch on a conventional power station to supply the demand. In addition, when there is wind, there may be no load demand; hence the wind turbines should be switched off. Shutting down wind turbines seems like a waste of green energy. This is where energy storage comes into play. When there is excess energy, we do not switch off the renewable source, but instead we store it as hydrogen. Whenever there is no renewable generation, then we just use the stored hydrogen as a fuel for electricity generation, cooking, heating, in vehicles and other applications. Therefore hydrogen energy storage will play a more role in our society as the renewable installations increases substantially at a global level.
