"Thibaut Duby from World Storage Presents Innovative Iron-Soled Battery Solution to Achieve 24-7 Renewable Energy and Support Net-Zero Electricity Systems at EES Event."

Thibaut Duby, responsible for business development at World Storage, introduces the company's innovative solution to achieving net zero in electricity systems: the iron-soled battery. Founded in 2016 in Munich, World Storage aims to make renewable energy available 24-7 through this breakthrough technology. The iron-soled battery leverages Redox flow concepts with separate cell stacks and electrolyte tanks that offer scalability and cost efficiency. This system can withstand high temperatures up to 55 degrees Celsius, lasts up to 10,000 cycles (translating into roughly 25-30 years), and relies on abundant local materials rather than rare earth metals. Duby emphasizes long-duration storage's importance for consistent green energy availability by citing a case where renewables alone only provide base load power about 55% of the time annually. Adding long-duration storage increases this figure significantly. He also discusses Germany’s future renewable targets and anticipates their technology meeting various durations of "dunkelflutter" events—periods with minimal solar or wind energy production. World Storage has a roadmap leading to large-scale deployments by late 2028 after demonstrating their first unit by end of 2025. They have substantial experience from deploying over 250 Redox floor systems globally. A significant case study involves AquaPower in the Middle East, where they aim to replace oil and gas turbines powering desalination plants with solely renewable energy using their iron-soled batteries designed for harsh environments.

Automated summarization by AI Conver

Storing energy for longer can safely provide additional flexibility for a power system relying on renewable energy sources, and thus plays an important role in a successful energy transition. Co-hosted by LDES and IBESA, this session will dive headfirst into the topic of long duration energy storage systems - learn about current market dynamics, technologies and more!
