    "goal": "Produce hydrogen on demand to replace fossil fuels and provide clean energy for marine, automotive, rail, aviation and power generation applications.",
    "problem_addressed": "Need for efficient, safe, and economical hydrogen production to reduce reliance on heavy, polluting fossil fuels.",
    "concept_summary": "The Phillips Method uses an electro-activated carbon (or lead) catalyst combined with water and an aluminum fuel to generate hydrogen on demand. Electrical energy activates the catalyst, which then reacts with water (or other hydrogen-containing liquids) and aluminum to release hydrogen gas. The reaction rate can be controlled by heating or cooling the mixture.",
