Hydrogen Production

Energy Requirements

• about 50kWhr [1] to produce one kg of hydrogen. At electrical costs of 10 cents per kWhr, that is $5 per kilo, equivalent to a $5/gal of gasoline cost for the Energy Density.
• For the Seed Eco-Home - the total installed marginal cost of 3kW is $2000 in 2017. This could produce 1 kg of hydrogen in 3 days. Perfect. Annual cost of fuel at $3/gal is $1200 - 400 gallons at 25 mpg - for 10k average miles. So we would get free fuel after 2 years of use.

• If cost over lifetime is considered - 20 years at 3kW of production yields 20*365*6*3 kWhrs = 131,400 kWhrs. This yields an energy cost of 1.5 cents per kilowatt hour. Or equivalent to 80 cent per gallon gasoline cost.

• This makes a great case for the Seed Eco-Home + Hydrogen Filling Station + Open Source Hydrogen Car + Microfactory + Aquaponic Greenhouse as a productive unit for civilization with automated food harvest and passive electricity and fuels production.

H from Aluminum

One way to generate hydrogen is by reacting aluminum with base such as NaOH.

This company promises $2000 home scale units for producing hydrogen at $1 per Kg
