The Iron Redox Flow Battery (IRFB), also known as Iron Salt Battery (ISB), stores and releases energy through the electrochemical reaction of iron salt. This type of battery belongs to the class of (RFB), which are alternative solutions to (LIB) for stationary applications. The IRFB can achieve up to 70% round trip . In comparison, other long duration storage technologies such as pumped hydro energy storage pr. [pdf]
Iron-based flow batteries designed for large-scale energy storage have been around since the 1980s, and some are now commercially available. What makes this battery different is that it stores energy in a unique liquid chemical formula that combines charged iron with a neutral-pH phosphate-based liquid electrolyte, or energy carrier.
Benefiting from the low cost of iron electrolytes, the overall cost of the all-iron flow battery system can be reached as low as $76.11 per kWh based on a 10 h system with a power of 9.9 kW. This work provides a new option for next-generation cost-effective flow batteries for long duration large scale energy storage.
A new iron-based aqueous flow battery shows promise for grid energy storage applications. A commonplace chemical used in water treatment facilities has been repurposed for large-scale energy storage in a new battery design by researchers at the Department of Energy's Pacific Northwest National Laboratory.
The trade-off is that iron batteries have much lower energy density, which means they can’t store as much energy as a lithium-ion battery of the same weight. And flow batteries require more up-front investment and maintenance than lithium-ion batteries.

China’s first megawatt iron-chromium flow battery energy storage demonstration project, which can store 6,000 kWh of electricity for 6 hours, was successfully tested and was approved for commercial use on February 28, 2023, making it the largest of its kind in the world.

Croatia satisfies its electricity needs largely from hydro and thermal power plants, and partly from the Krško nuclear power plant, which is co-owned by Croatian and Slovenian state-owned power companies. Renewable energies account for approximately 31.33% of Croatia's energy mix. .

Total energy supply (TES) includes all the energy produced in or imported to a country, minus that which is exported or stored. It represents all the energy required to supply end users in the country.
In February 2020, the Croatian government adopted a new Energy Strategy for the period until 2030, with an outlook through 2050. The Strategy includes a wide range of energy policy initiatives that will improve energy security, increase energy efficiency, lower dependence on fossil fuels, increase local production and increase renewable resources.

Croatia imports about 54.54% of the total energy consumed annually: 74.48% of natural gas, 78.34% of oil and petroleum products, and 100% of its solid fossil fuel needs. Croatia also co-owns the Krsko nuclear reactor in Slovenia, which is included in its energy mix as imported electricity.
Renewable energies account for approximately 31.33% of Croatia's energy mix. Hrvatska elektroprivreda (HEP) is the national energy company charged with production, transmission and distribution of electricity.
