Agricultural work is determined by weather, seasons, soil conditions, plant growth, and harvest windows.
Energy is therefore not always needed exactly when the sun, wind, or other energy sources are directly available.
Irrigation, cooling, processing, mowing, harvesting, or transport may also be necessary at times when little renewable electricity is being generated.
Energy storage therefore bridges energy production and energy demand.
It makes energy temporally shiftable.
However, this also results in additional losses, material requirements, and technical dependencies.
Energy can be stored in various forms.
These include, among others:
Agriculture has always worked with energy storage systems.
Plants store solar energy in biomass.
Humans and animals store energy in their bodies.
Wood, plant oils, biogas, and other fuels store chemical energy.
Newer technical systems complement these forms with batteries, heat storage, hydrogen, and larger power grids.
Many agricultural tasks are time-critical.
Examples include:
These activities cannot be arbitrarily postponed.
The more agriculture is electrified and automated, the greater the need for available and storable energy may become.
Biomass is a biologically derived form of stored solar energy.
This includes:
Biomass can be storable and used as needed.
However, its use is tied to land, growth, water, soil fertility, and ecological limits.
Biomass should therefore not automatically be considered an unlimited energy source.
Diesel, gasoline, plant oils, and other liquid fuels have a high energy density.
They can be easily stored and transported.
They are therefore frequently used in agriculture and logistics.
Their advantages include:
Their disadvantages may include:
Batteries store electrical energy chemically.
They can be used for:
Batteries enable the direct use of electrical energy.
However, they require:
Aging and limited charge cycles must also be considered.
Heat storage systems can store energy in the form of heat or cold.
Possible applications include:
Possible storage forms include:
Heat storage can be particularly useful when heat is used directly and does not need to be converted multiple times between different energy forms.
Hydrogen can chemically store electrical energy.
It can later be used for heat, electricity, mobility, or industrial processes.
However, this involves several conversion steps.
These can result in significant energy losses.
Additionally required are:
Hydrogen can be useful for certain applications but should not be viewed as a loss-free or unlimited solution.
Power grids also serve a storage and balancing function.
They connect different regions, generation facilities, and consumption times.
A grid can balance fluctuations without every individual farm needing its own complete storage system.
This requires:
Grids do not completely replace storage but can reduce local storage needs.
Energy cannot be stored and released without losses.
Losses occur, for example, due to:
The more conversion steps are necessary, the greater the total loss may become.
A central question is therefore:
Can energy be used as directly as possible in the form in which it is generated?
Direct use is often more efficient than multiple conversions and storage.
Storage systems themselves require energy and materials.
These include:
The production of a storage system is therefore part of its energy balance.
A complete assessment must consider:
A storage system can be technically efficient yet still incur high material costs.
Automated agriculture often requires energy regardless of time of day or weather.
Robots, sensors, pumps, control systems, and digital systems should function even when little energy is being generated.
Automation can therefore create additional storage needs.
This raises the question:
Is a task automated because it is overall more sensible—or does automation create a new, permanent energy and storage requirement?
Biological and technical storage systems serve different purposes.
Biological storage systems include, for example:
Technical storage systems include, for example:
Biological storage systems are part of living cycles.
Technical storage systems enable targeted availability but require additional infrastructure.
Sustainable agriculture combines both forms where they are each appropriate.
The following questions can help evaluate a storage system:
Energy storage is closely linked to:
This article aims to consider energy storage not merely as a technical issue.
Storage affects:
The goal is not to store as much energy as possible.
The goal is to first reduce energy demand, use energy as directly as possible, and only store energy where it is truly necessary for a sustainable agricultural system.
