The aim of the RETO-DOSSO research project is to contribute to sustainable livelihoods in the rural areas of Niger by creating essential basics and enabling rural entrepreneurial activities. To achieve this, the researchers use electricity from renewable sources to provide basic needs such as water and food. Surplus electricity from a decentralized solar energy system strengthens rural economies by generating simple, but creative business ideas as local sources of income.

Despite the improvements of the global energy supply in the last years, more than one billion people worldwide don’t have access to electricity[2], the majority of them living the sub-Saharan Africa[3]. Moreover, a secured access to water and food is a critical topic. Therefore, it exists an urgent need of a sustainable economy, which ensures the basic life standard and the well-being of the people in the rural areas of  West African countries. Furthermore, the climate change and the steady increasing number of the worldwide population will increase the need for energy, water and food in the future. Especially the secure supply of these needs, as well as health security will gain rising importance for the worldwide society.

As a result, the overall objectives of the project “RETO-DOSSO” is to build up a long-term and sustainable livelihoods in the rural areas of sub-Saharan Africa and to establish a long-standing research and education cooperation between Germany and Africa. Alongside the project-related objectives, the initiated collaboration of different universities, research institutes and business partners of Germany and Africa (Niger, Mali and Algeria) is expected to generate different synergies and mutual benefits by linking, extending and intensifying unique networks of partners, sharing experiences in teaching and research.

The project is financed by the German Federal Ministry for Education and Research (BMBF) as well as supported by the Through the Project Management Agency Jülich (PTJ).

Hybrid Energy Lab

installation and training

The laboratory comprises three test stands: Hydrogen Renewable Energy Trainer (HRET), Fuel Cell Trainer (FCT) and Solar Hydrogen Trainer (SHT).

The HRET has various individual modules that can be interconnected. The large number of modules enables not only basic experiments, but also the investigation of real, operational problems such as

shading of PV systems. In addition to the energy source (230 V connection), the test objects in the form of photovoltaics (PV), wind turbine and a fuel cell can be investigated by means of measuring and control units as well as by means of safety devices. For fuel cell operation, there is an external hydrogen generator and two metal hydride storage tanks.

The FCT consists of a low-temperature fuel cell (PEM fuel cell, stack power 50 W) with a metal hydride storage (200 Nl). In addition, there is a variable electronic load, a load in the form of a traffic light, as well as a transformer to raise the output voltage of the fuel cell (4 V… 9.5 V) to 12 V. All measurement data are displayed directly on the FCT by means of analogue displays. The FCT can be connected to a computer. The corresponding software can be used to record measurement data. In addition, the experiments can be carried out with or without computer support.

The SHT is intended to explain the practical generation and application of solar energy. A functioning 230 V operating voltage is provided by two PV modules, 325 Wp each, connected in parallel, as well as an inverter or rectifier with integrated buffer storage, two 12 V lead acid batteries (60 Ah) connected in series. External devices such as the hydrogen generator (up to 72 l/h hydrogen) can be operated via the 230 V operating voltage. Thus, the SHT reflects the overall picture of a modern PV system, with the possibility of hydrogen production.
