Energy storage in batteries or chemical fuels such as hydrogen or synthetic natural gas (produced through water electrolysis) will be crucial to the worldwide large scale deployment of fluctuating renewable energies.

As the use of renewable energies grow and technologies mature, the market for storage will gradually increase, offering strong first-mover advantages to a range of potential stakeholders.

Among the different technologies that can be deployed as energy storage, Redox flow batteriesandelectrochemical generation of hydrogenhave been identified as strategic

At De Nora, we are therefore focusing our R&D on:

• pure flow batteries (hydrogen / bromine, and other redox couples),
• hybrid flow batteries (zinc / bromine)
• metal / air batteries.

Regarding water electrolysis, strong efforts are currently being made onAlkaline Water Electrolysisfor medium large scale installations (> 50 Nm/h as hydrogen generation capacity).

In a world where high-density living in urban areas is increasing, and healthcare and the spreading of pandemics are among top concerns, the role of the cleaning industry is of great importance, though often underestimated.

Our commitment is to promote technological advancements for better standards of cleanliness, to help reducing the risk of infection transmission within public spaces.

We develop small-scale systems for theon-site production of sodium hypochloritesolutions, an effectivesanitizerto be employed on several surfaces, including frequent-hand touch sites.

Different sizes of user-friendly devices, based on electro-chemical technology, generate ready-to-use sanitizing products in different concentrations from simple elements such as water, salt and electricity.

Amongkey advantagesof our sodium hypochlorite solutions are:

Effectiveness against viruses, bacteria, fungi and spores;

Sanitizing, cleaning and deodorizing properties;

Low cost of source materials (water, salt and electricity)

No caustic stabilizer contents;

Constant production quality, short production cycles;

Environmental friendliness (no harmful chemicals, less plastics used, limited packaging and transport costs)

In addition, hygienically cleaner spaces may contribute strongly to the profitability of businesses, connected to a more pleasant user experience and brand reputation, as proven by market researches for example in the fitness sector.

We are one of the major supplier ofanodes for sodium and potassium chlorate production, used by Pulp and Paper Companies as environmentally-friendly bleaching agent (EFC Elementary Chlorine Free Process).

Our Company offers a high level of specific know-how in design and manufacturing of cells and anodes for chlorate production.

De Nora's portfolio and services can be listed as:

• Manufacture of DSA electrodes;
• Manufacture of high performing catalytic coatings for anodes and cathodes;
• Manufacture of cell separators (PMX for diaphragm cells);
• Refurbishment and repair capabilities.

De Noracurrently has strong ongoingagreements with major technology and process owners in this field.

Nickel and cobalt production, precious metal refining (gold, silver), recovery of copper from bleed streams or valuable metals from industrial wastewater, are some of the applications of our titanium DSA anodes.

Power saving, enhanced productivity and operation improvement are the results of using De Nora titanium insoluble anodes in electrowinning applications.

Since 1972, we have worked to improve anode coatings to better serve nickel and cobalt refineries and today we count more than 40.000 De Nora DSA anodes installed in refineries and recovery operation plants, providing high efficiency and optimum quality of recovered metal. We offer a very a wide array of energy-efficient products for the electrowinning of non ferrous metals.

De Noras R&D department continues to develop new products for copper and zinc electrowinning. We are constantly looking for innovative solutions that ensure performance improvements under a technical and cost-effectiveness standpoint.

INDUSTRIAL PROCESS WATER TREATMENT

Water is an integral part of the mining and metal production process. Large quantities of water are required in sufficiently high quality for all areas of mine operations from exploration, mining, processing, smelting and refining. The requirement to provide treated raw water through to water reuse.
- Treat raw water for pre-treatment- Remove suspended solids, colloidals, organics, iron, manganese and other contaminants from raw water source- Provide high quality water for process or boiler feed using Reverse Osmosis- Treat and reduce effects of Acid Rock Drainage using reverse osmosis- Treat cooling tower water or process water using disinfection technologies such as sodium hypochlorite- Treat wastewater- Treat contaminated water for environmental discharge or reuse using membranes

Our roots in the chlorine, caustic soda and potash industry run deep, from the creation of the earliest commercial diaphragm cells in the early 1920s, through mercury cells in the 40s to the development of the very first membrane cell in the 70s concentrating nowadays on the most competitive and performing electrode structures and catalytic coatings

Whether your structure requiring protection is a gas pipeline, a steel tank or a re-enforced concrete deck, De Nora produces a cathodic protection anode for your application, both LIDA and ELGARD lines of CP anodes are commercialized mainly through a network of licensed distributors or authorized customers.
