Green hydrogen derived from renewable energy sources is especially key to decarbonising hard-to-abate sectors, such as steel production.
The company’s patented components are used in third-party systems for applications such as combined heat and power generation, green hydrogen production, renewable energy storage, and syngas production for synthetic fuels and chemicals. On route to a fossil-free future, Elcogen’s scalable, eco-friendly power solutions enhance energy security by supporting low-carbon transition fuels, such as biogas and natural gas, and enabling reliable, localised power in island mode, ensuring energy supply even during grid disruptions.
