A demonstration plant of the German Energy Agency as well as the two German companies Bioltec Systems GmbH and Sunfarming GmbH will show how food cultivation, energy production and mobility can interact efficiently and sustainably.
The German Energy Agency (Dena) has launched an extraordinary pilot project in its Renewable Energy Solutions program (Dena RES program). In cooperation with the two German companies Bioltec Systems GmbH and Sunfarming GmbH, a training and demonstration center for the German Energy Agency (DMA) has been set up Renewable energy, energy use of waste and sustainable mobility in the Caribbean combined with intelligent control of the overall system.
As a hybrid center, the trend-setting facility combines several technologies: A combined heat and power plant supplies electricity and heat to a school on whose grounds the project was realized. The special feature of this plant is that it is operated with biodiesel. This fuel can be made, for example, from used cooking oil that exists on the island. In addition, this biodiesel will be used to operate specially converted vehicles used in Bahamas waste management.

Electricity for irrigation and vehicles
In addition, a greenhouse with a photovoltaic system was built. On the one hand grow food in it, on the other hand, the greenhouse produces not only the power required for their own drip irrigation, but can also feed into the home network or in the battery system for an emergency power supply. The battery system also serves as a charging station for e-bikes and e-motorcycles. An intelligent controller ensures that such a system can also work in off-grid regions.
The reference plant will produce a total of around 50,000 kilowatt hours of electricity and 80,000 kilowatt hours of heat from renewable energies annually, thus avoiding 40 tonnes of carbon dioxide emissions. It shows how food cultivation, energy production and mobility can interact efficiently and sustainably, and already serves as a visual aid for teaching environmental management.

First Hybrid Center for Renewable Energy in the Bahamas

The first SUNfarming/bioltec Hybrid Center for renewable electricity and renewable mobility in the Bahamas was inaugurated on 10th December.

The Bahamas Hybrid Center offers renewable electricity and renewable mobility combined with food production, all coupled to a one-site training program - a very unique concept.
The German companies SUNfarming GmbH and bioltec systems GmbH , in cooperation with the Bahamian company 700 Islands Energy, have set up a hybrid center for renewable energies at the Windsor High School in Albany, Nassau.This project is part of the worldwide dena Renewable Energy Solutions Programme coordinated by the Deutsche Energie-Agentur (dena) - the German Energy Agency - and supported by the German Federal Ministry for Economic Affairs and Energy (BMWi) within the German Energy Solutions Initiative.

More than 40 political, business and university guests attended the opening ceremony on the campus of Windsor High School.
After the opening speech by Peter Schrum, company founder and main shareholder of SUNfarming, guests had the opportunity to visit the center, accompanied by knowledgeable experts who gladly answered all questions.

In this Hybrid Center, a greenhouse with roof integrated photovoltaic panels, electricity is generated from sunlight, while vegetables, fruits, flowers or medicinal herbs are grown indoors with high yield. The integration of renewable energy into a combined heat and power plant generates electricity and hot water at the same time. A smart grid management system makes the power together with a battery storage as a 24/7 stand-alone solution and / or grid-connected. Electric and fuel vehicles clearly demonstrate renewable mobility.
At the same time, SUNfarming and bioltec are striving to promote climate and resource protection, to shorten regional value chains, to provide energy, to create jobs and ultimately to increase the quality of life sustainably. The competencies of both companies have been integrated into the design. Demonstration, training, application and technology transfer of proven leading-edge technologies are the keywords for this "Bahamian - German Hybrid Center". In addition, it provides the foundation for future collaborative research and development, including business models for commercial applications. The partners bring together different systems integration technologies, whether for off grid or grid-connected applications that are adaptable to local conditions and customer needs.
