Problem
Traditional green hydrogen production methods often involve separate systems for electrolysis and energy storage, leading to inefficiencies and increased complexity. Fluctuations in renewable energy sources can also make it difficult to ensure a consistent and cost-effective supply of green hydrogen for industrial applications.
Solution
STOFF2 provides an integrated green hydrogen production solution using its Zinc Zwischenschritt Electrolyzer (ZZE) technology. The ZZE system combines electrolysis and energy storage in a single unit, enabling efficient use of renewable energy sources like solar and wind power. By storing energy in solid zinc, the system decouples power intake and hydrogen production, allowing for on-demand hydrogen generation and grid stabilization. This approach reduces hydrogen production costs by utilizing power during off-peak hours and provides a reliable supply of green hydrogen for various industrial applications.
Target Audience
STOFF2's primary customers include industrial companies, public utilities, wind and solar farms, and sustainable chemical producers seeking a reliable and cost-effective supply of green hydrogen for decarbonizing their operations.
