Safe hydrogen storage vessels and purification vessels as well as high-pressure vessels from VAKO.
Competence from the manufacturer.
For more than 40 years, VAKO GmbH & Co. KG has stood for uncompromising safety and exceptional quality in type-1 hydrogen storage vessels. As a family-owned company in Kreuztal, Germany, we combine tradition with innovation and supply sustainable hydrogen storage solutions that are used worldwide in industry, research, infrastructure, mobility, special projects, and the energy transition.
VAKO’s unique testing concept significantly reduces recurring maintenance costs and enables all inspections to be conducted from outside the pressure vessel without any hydrogen losses, flushing, or downtime – for maximum cost effectiveness and minimal operational impact. We easily exceed established market standards with around 60 specialists, cutting-edge manufacturing technology, and 100% weld seam testing using complementary processes.
VAKO drives the push for a safe, climate-friendly energy future with its certified, sustainable hydrogen storage vessels in standard sizes or custom design vessels up to 330 bar.
