Welcome to Green Fortress Engineering
Green Hydrogen Solutions
Hydrogen Storage - Solid State
Clean. Abundant. Flexible.
Green Fortress has patented technology for storing hydrogen in catalytically-modified porous silicon. Launches past compressed gas or cryogenic storage. Stands above metal hydrides or MOFs.
Low-cost. Convenient
Cost projections show that hydrogen from renewable sources (biomass or solar-split water) can be stored at costs below 8 USD/kWh. System scales range from "smart dust" to grid-level energy storage.
Renewable Energy Breakthrough
Hydrogen from biogas can be stored in porous silicon: smaller, lighter, and safer than battery storage.
