WHAT ARE ENERGY STORAGE SYSTEMS?
Electric energy storage systems are already in use in many countries. In Brazil, this technology offers an important alternative for optimizing the use of electricity generated by photovoltaic systems. BESS – Battery Energy Storage Systems – not only enable the storage of electricity generated from sunlight but also ensure continuous and efficient energy supply.
Among the main storage technologies are: lithium-ion batteries, flow batteries, and sodium-sulfur batteries.
The stored energy can be used when there is no electricity from the solar photovoltaic system or the grid supplying the system, such as during blackouts, cloudy days, or at night. Effectively storing the electricity generated by solar panels ensures stable supply, reducing dependence on the conventional power grid and promoting more sustainable energy management.
GREEN HYDROGEN: THE FUEL OF THE FUTURE
Green hydrogen represents a revolution in the field of sustainable energy. It can be produced through the electrolysis of water—a process that uses electricity to split water molecules (H₂O) into hydrogen (H₂) and oxygen (O₂). When the electricity used in this process comes from clean, renewable sources such as solar energy, the result is hydrogen that is entirely free of carbon emissions.
In heavy industry, green hydrogen (H₂V) can replace fossil fuels like coal in steel production and be used in the manufacturing of ammonia and methanol. In the transport sector, hydrogen fuel cells are being adopted for heavy-duty vehicles, offering a clean alternative, particularly in aviation and maritime shipping.
In addition to being a renewable energy storage solution, green hydrogen can also replace natural gas in heating systems. Countries like Brazil, with a surplus of competitively priced renewable electricity, could become global leaders in the green hydrogen market.
