Keynote: Sustainability – from a fuzzy concept to a guiding principle

A recent online article is aptly titled: “Sustainability – confusing term for a clever concept“. This nicely summaries both the beauty and challenge in dealing with this important concept. The idea of  sustainability first emerged with regards to forestry,  where  it  means  never  harvesting more  than  what  the  forest  yields  in  new  growth. The  word “Nachhaltigkeit”  (the  German  term  for sustainability)  was  first  used  with  this  meaning  in  1713. Since then the concept of sustainability has come a long way.  In general terms, sustainability means meeting our own needs without compromising the ability of future generations to meet their own needs. However, this is not restricted to the natural environment but also extends to social and economic resources. Thus, sustainability goes beyond environmentalism and also encompasses social equity and economic development. Sustainability can also be understood as a movement which has its roots in social justice, conservationism or internationalism. By the end of the 20th century, many of these ideas were united under the roof of “sustainable development” and found their most prominent expression in the Sustainable Development Goals (SGD) as the current global agenda for reducing poverty and raising the quality of life. Sustainability as a political and strategic concept has its origin in the Brundtland Report “Our Common Future” of 1987. The report was concerned with the tension between the aspirations of mankind towards a better life on the one hand and the limitations imposed by nature on the other hand.

The presentation traces the history of the concept of sustainability and critically discusses its many dimensions.

Session A: Economics of Battery Use in Agriculture: Economic Viability of Renewable Energy Complemented with Batteries in Agriculture

The production of renewable energy fluctuates in terms of sun and wind and must be supplemented by storage in the system. On an individual basis, i.e., for centralized electricity production and predominantly self-consumption, the use of batteries is considered here. Possible future development scenarios were simulated based on current price relationships (status quo). In the status quo, a selling price for PV electricity of 13 Euro cents (ct)ct/kWh was assumed with a production cost of 11 ct/kWh. The selling price of wind power is 5 ct/kWh with a production cost of 3 ct/kWh. The cost of storing electricity in a battery increases the price by 33 ct/kWh. A price of 20 ct/kWh is assumed for electricity purchases by companies. In the status quo, the use of batteries is not economical given the assumed price relationships. Changing the framework conditions, such as those of the legislature in Germany with the nuclear power phase-out and in the EU with the coal exit and decarbonization, will lead to increased availability of (fluctuating) renewable electricity, especially during the day. The purchase of electricity at other times, when the supply is scarce, can lead to increased electricity prices, especially at night. Together with falling costs for storage, the use of batteries for centralized power generators could be very interesting in the future. The method used in this study is nonlinear optimization of the target function costs of electricity supply in the developed simulation model. The results can also be transferred to other countries, as the assumed trends apply worldwide.

Session A: Hybrid Energy Storage System as Active Power Filter

The presentation is about the use of a hybrid energy storage system (HESS) as an active power filter for advantageously stabilize the volatile power output of a wind turbine. For this purpose, a HESS (25 kW / 25 kWh) consisting of lithium-ion batteries (200 x 3.2 V / 40 Ah) and double-layer capacitors (12 x 48 V / 156 F modules) was set up in the laboratory at Stralsund University. A fluctuating power conversion is simulated by a 20 kW engine test bench with an asynchronous generator. The HESS uses the advantageous properties of both energy storage technologies. These enable the power flow at the grid connection point to be stabilized, from highly dynamic load peaks to longer-term power changes in the hourly range. A major advantage of this storage combination is the reduced cycle load of the lithium ion batteries due to the corresponding use of the double-layer capacitors. A design of the HESS components optimized for the respective work cycle, together with optimized operation, ensures an increased service life of the LIB.
