EcoInn Danube - Containerized energy
20-12-2017
The philosophy of a Hungarian company named JKH is always to follow and deal with state-of-the-art and cutting edge technology, they also do it in the “traditional” photovoltaic industry. Their staff is very enthusiastic to work with innovative project and that played a key role in starting designing and realizing their new product which is the containerized, off grid electricity producing and storing power system. It is capable to supply electricity to a household throughout the year without interruption at 3 x 16 Amp, max 10 kWh/day.
The goal of designing the product was to produce and store energy, without increasing CO₂ level in the atmosphere, in rural, faraway places where grid connection is not available. By applying already known processes and solutions, combining them in an innovative way, we met the requirement of the targeted goal. Storing in, and regaining energy from hydrogen, solve the problem of long term storage of photovoltaic energy for periods when the sun doesn’t supply enough energy. Both the energy production and the storage of it are under full IT control.
The demand for an innovative solution to supply electricity to locations where there are no public grid came from E.ON because, they faced a problem: where the distance between an existing grid and the consumer was more than 1,700 meters, the costs of connecting the consumer to the grid was unbearable both for the consumer and the service provider company. They found out that there were more than 6,000 such places alone in Hungary. They are the main target users of the product. Besides that, there are more and more environmentally conscious people who can afford to invest into such environment friendly solutions.
The container consists of two main parts:
- Energy production: this section controls and converts electricity produced by the 10,8 kWp PV array
- Hydrogen section: produces hydrogen from not used electricity and electricity from hydrogen
This eco innovative solution saves the atmosphere from 7.8 tons of carbon dioxide in every year, which is a significant impact in such a small location. The economic impact of it is that it pays back the invested money right away as it starts functioning since it is less expensive than to build the grid. The cost of operation is so small, you can hardly measure. But the social impact is greater than the former two: an isolated family that haven’t had access to electricity now is “connected” to modern society, they can use household appliances – e.g. washing machine, TV, computers, etc. – and the Internet which is essential today.
