$PLUG Bullet Points – Part 3 WHY GREEN HYDROGEN? Green Hydrogen Applications 1. Transportation: Eliminates pollution generated by cars, buses, trucks, airplanes and ships 2. Chemical Industries: Reduces metal oxides to metals, HCI and production of methanol, ammonia 3. Industries: Eliminates fossil fuels in the production of steel, cement, glass 4. Space: Used as rocket and space shuttle fuel 5. Food Industry: Hydrogenation of unsaturated vegetable oils 6. Residential: Power houses, backup power In 2025 the “Hydrogen Industry” produced approximately 1% of the total energy produced by oil, natural gas, coal, nuclear, solar, wind and geothermal. Of that 1% green hydrogen accounted for approximately 4% of the 1%. Green hydrogen market share when produced at $1/kg using the recent iridium reduction coating technology: 2030: 4.0% of the world energy market 2040: 8.0% of the world energy Market The world energy market in 2025 was approximately $9 trillion dollars!

$PLUG Bullet Points – Part 2 Colors of hydrogen - 5 different categories: • 1. Brown: Burning fossil fuel, hydrocarbon cracking & coal gasification with high CO2 emissions • 2. Grey: Steam Methane Reforming -released CO2 directly into the atmosphere • 3. Blue: Steam Methane Reforming with carbon capture • 4. Pink/red: Nuclear-powered electrolysis • 5. Green: Renewable-powered electrolysis Cost of hydrogen by color: • Brown - $2.50/kg • Grey - $3.00/kg • Blue - $4.00 to $5.00/kg • Pink - $5.00 to $8.00/kg • Green - $6.00 to $8.00/kg Production of Hydrogen by Energy Source: • Natural Gas – 48% • Coal – 38% • Oil – 18% • Renewable Energy – 4% The production of hydrogen through SMR, coal gasification, burning of fossil fuels, and hydrocarbon cracking emits GHG and toxic effluents into the atmosphere severely affecting the world climate. Unfortunately the use of natural gas, coal, and oil accounts for roughly 96% of the hydrogen produced in the world today.
