Problem
Current renewable energy systems lack a practical method for long‑term, high‑density storage and transport of clean power, making it difficult to replace fossil fuels for applications that require energy on demand, such as industrial heat or remote power supply.
Solution
Hydral offers a carbon‑free energy storage and transport platform that uses aluminum as a recyclable fuel. Their reactors convert stored aluminum back into hydrogen and heat by reacting it with water, producing only recyclable aluminum oxide as a by‑product. The oxide can be re‑electrolyzed into fresh aluminum, creating a closed‑loop system that can store energy for days, weeks, or even centuries. Because aluminum’s energy density exceeds that of conventional fossil fuels, the stored energy can be shipped globally and released on‑site without the need for catalysts or additional inputs. This approach enables the delivery of industrial‑grade heat and hydrogen to hard‑to‑decarbonize sectors while maintaining a fully circular material cycle.
Target Audience
Primary customers include industrial manufacturers, maritime and logistics operators, and remote power providers that need reliable, high‑density energy storage and on‑site heat or hydrogen generation for hard‑to‑abate processes.
Features
- Aluminum fuel cartridges that encapsulate stored renewable energy in a stable, compact form
- Reactor units that generate hydrogen and high‑temperature heat on demand using only water as a reactant
- Production of recyclable aluminum oxide as the sole waste, which can be recharged into fresh aluminum via electrolysis
- Energy density higher than traditional fossil fuels, allowing efficient maritime transport of stored energy
- Capability to provide continuous power for extended periods (days to centuries) without degradation
- No requirement for external catalysts or complex supply chains during energy release
