Green alternative to polluting diesel generators
Music festivals, houses or farms in remote, rural locations, temporary offices, telecom antennas, refrigeration systems for the storage of medical materials or even emergency hospitals and schools in disaster areas. For applications like these, electricity is currently supplied by diesel generators. But these generators easily consume 30,000 litres of fuel per year. Tiger Power founders Chris Prengels and Jessica Reznor were convinced that there had to be a better way.
Chris Prengels: “During a stay in India, where some 250 million people have no access to electricity, we saw the urgent need for simple, smart and scalable plug-and-play systems for energy provision and storage. That experience brought us to the development of two revolutionary products: Sunfold® and Storager®.”
Flexible and modular power station running on solar energy and hydrogen
The patented Sunfold® is an unfolding, pre-assembled PV system with integrated batteries that fits on top of a container. Folded up, three stacked Sunfolds® are the same size and just as easy to transport as a regular shipping container. Once on-site, the Sunfold® is installed and unfolded in just half an hour after which it is immediately capable of generating 11 to 27 kilowatt-hours of green energy every day. Energy that can be consumed immediately or stored, to guarantee the supply of power before sunrise and after sunset. The combination of solar energy with battery storage within one plug-and-play product is unique.
The Storager® is a unit that can store up to 300 kilowatt-hours of green energy in the form of hydrogen for an extended period of time. With this innovative concept, rain or groundwater is converted to hydrogen and stored. When energy is needed, a portion of the hydrogen supply is converted to electricity. The use of hydrogen as an energy carrier is also on the rise in other sectors, for example, in electric cars. But Tiger Power is the first to apply this technology to a product for long-term energy storage. Just like the Sunfold®, the Storager® is also compact and easy to transport. They can both be set up and stored away in less than 30 minutes but are built to last for over 20 years.
Proactive and intelligent software
The Storager® can be used in combination with other sustainable power stations, such as small wind turbines or small biomass power plants, or with one or more Sunfolds®. Together, the Storager® and the Sunfold® form a Power camp®, a small electricity power station which is completely independent of fossil fuels and which can supply 100% green energy around the clock, all year long. Thanks to the Tiger products' intelligent software, the demand for electricity, on the one hand, and the availability of solar power, on the other, are kept in perfect balance.
CTO Jessica Reznor: “For the development of this software, we called on the support of the VITO (Vlaams Instituut voor Technologisch Onderzoek - Flemish Institute for Technological Research). Together, we are working on a proactive and self-learning system. A system, which learns, for example, at what time of day there are peaks in energy consumption and then capitalises on this by building up a supply outside of these peak moments.”
Local branch in India
In view of the market roll out of its products, Tiger Power is starting up a branch location in India. The ambition is to build 100 mini-grids in East India and 200 in Sub Saharan Africa in the coming years. Therefore, Tiger Power will also participate in project development via so-called Renewable Energy Service Companies or RESCOs, individual corporations that Tiger Power launches as joint ventures together with local actors.
