Profitable, versatile, modular: Energy Campus

Our modular power plant takes up the solarwind technology and expands it at the same time: the solar collector output of the Energy Tandem is limited by large wind forces. Taking this into consideration and wanting to extend the advantages and patents of the Energy Tandem concept into the MW output range, the Campus 4 – 8 concept was developed. This consists of a mast designed as a pressure vessel, which carries a larger wind turbine compared to the Energy Tandem and also serves as an energy or hydrogen storage. The solar collectors of the Energy Tandem supplement the performance of the Energy Campus here as ground-connected Trackers with a selectable number according to the modular principle.

The Campus line is available in versions 4, 6 and 8 with electrical outputs of 1.5 to 3 MW and H2 outputs 300 to 600 Nm3/h.

The solarwind Energy Campus power plants are also equipped with an electrolyser to produce gaseous hydrogen as well as with an energy storage system. The wind turbine mast is designed as a pressure vessel and serves as a hydrogen storage. The installation of a fuel cell to cover possible electricity peaks is also planned.

An intelligent upgrade of renewable energy: Retrofitting wind power plants

The advantage of a solar energy storage with simultaneous extension of operating times of wind power plants is achieved by retrofitting them with a solar conversion system that uses 67 % (27 % electrical, 40 % thermal) of the solar rays. This will also make it possible to serve the heating market with the process waste heat that accumulates. The solar energy potential of the energy storage system, if and when possible enriched by the conversion of surplus wind power, is available as a base load and to cover periods of no wind. The generation of other supply products such as hydrogen is also possible by using the value chain of the self-generated electricity.

The solar system part of the Energy Campus 4-8 product line is used for retrofitting, currently with the following retrofit electrical nominal outputs:

Electric powerThermal heat
Retrofit Campus 4 NR500 kW1,500 kW
Retrofit Campus 6.NR750 kW2,200 kW
Retrofit Campus 8 NR1,000 kW3,000 kW

43/40° C, 95/90° C thermal heat / district heat

We recommend a ratio of wind to solar capacity of 2:1.
