Energy – essential for our daily life – is required for all natural processes as well as a source for heat, light and running equipment.
The Lohtragon® metal salts contribute to a sustainable energy generation and storage across various types of energy. In many systems these high performance metal salts act as active component like in thermal energy storage and batteries. In other energy sectors metal salts are used as auxiliary materials and to optimize production processes, e.g. as hydrogen sulfide scavenger in biogas plants.
Stocking thermal energy by heating or cooling a storage medium is an important pillar of a renewable energy storage concept.
Latent heat storage
Latent Heat Storage Systems use specific Phase-Change Materials (PCM), typically metal salts. These salts, hydrates and anhydrous salts as well as their mixtures, release heat with the phase change from liquid to solid and are charged by heating with renewable energy (melting the solid material into its liquid phase). The Lohtragon® portfolio offers a dedicated range of Formates and Acetates as well as magnesium and Lithium mixed salts. The Lohtragon® competences in metal salt modifications support to enhance the heat transfer efficiency by product encapsulation, particle design and other types of modifications.
Thermo-chemical Heat Storage
The dehydration of a metal Hydroxide into its oxide and water is one example of a solid-gas reaction for thermo-chemical heat storage, for example Magnesium and Calcium Hydroxides. Important is the optimization of the operating temperature by the right choice of additives.

Battery Energy Storage (BES)
Batteries is what immediately comes to our mind when we think about electric energy storage. more
Batteries are what immediately comes to our mind when we think about electric energy storage. This power source is not only one of the fastest growing industry segments but also highly driven by innovation and optimization of its technology.
Rechargeable batteries
Huge efforts are spent on the optimization of lithium-ion batteries (LIB) for electrical vehicles (EV) and for other electrical devices. Ongoing research and innovation permanently extend the already broad variety of lithium-based batteries like Lithium Iron Phosphate (LFP). Additional technology is required to fulfil the manifold needs in various energy storage systems, e.g. rechargeable batteries. Metal salts based on iron, manganese and many other materials are the basis for batteries used and developed for e.g. stationary batteries. Lohtragon® metal salts are precursors for various active materials used in current rechargeable battery types.

Fuel cells
Generating electricity by combining hydrogen with oxygen while forming a harmless byproduct, water, is the short version of the fuel cell technology while its market implementation is highly complex. With the Lohtragon® competences we are heading to contribute to new developments in this field. Examples are the solid oxide fuel cells (SOFC), containing ceramics based on metal Oxides and the molten Carbonate fuel cells (MCFC) which use Carbonates based on Sodium, Magnesium and Lithium Potassium as an electrolyte.
Redox flow batteries
Due to their specific performance profile, redox flow batteries are predominantly suitable for stationary energy storage. Vanadium-based systems are considered as standard technology and other potential electrolytes are based on Iron, Zinc or systems under development. The Lohtragon® team is highly interested in looking into innovations for energy storage systems.
The production of biogas – an organic renewable energy source – always generates toxic hydrogen sulfide. A full range of Iron based Lohtragon® metal salts is available to remove hydrogen sulfide for further use of the biogas. A selection can be made according to solubility and pH-value/level, depending on requirements.
Along the value chain of the oil and gas industry there are several steps requiring metal salts to ensure efficient and safe processes.
Exploration and production
The cementing protects and seals the well bore. Processing the cement and achieving specific physical properties requires a set of additives added to the cement slurry. The setting time is important for the process. The reaction is adjusted with admixtures, such as accelerators and retarders.
During the drilling step processing fluids enhance the efficiency with a complex requirement profile. One important characteristic is a reliable pH level control to provide fluid stability and control of contaminants.
In the upstream production process, metal salts are used as hydrogen sulfide scavenger. Crude oil can contain a large proportion of hydrogen sulfide, which is toxic and extremely corrosive in contact with water. The combustion product sulfur dioxide is equally aggressive and harmful to health. Therefore, for health and environmental protection and for economic reasons, hydrogen sulfide quickly has to be removed from crude oil and natural gas.
