Grothe Power Tower Project

How it Works! 

1) Grothe Power Tower receives surplus energy from a renewable energy source like solar or wind through a common electrical connection. 



2) Using a hydrogen fuelcell the power is converted and stored as a gas in a water tower like device called a Grothe Power Tower.    (patent pending design)




3) Using the same fuelcell we convert the stored energy (gas) in the power tower back into an on-demand electrical load ready for home or local community when the sun isn't shining or the wind blowing. Making the Grothe Power Tower an ideal energy storage solution for renewable energy devices.





What is a Hydrogen Fuel Cell?

pem-fuelcell-diagramHydrogen FuelCells and Solar/Wind Power

Hydrogen is the most abundant element in the universe, and it is also the element with the most energy per unit of weight! However, hydrogen gas does not exist naturally on earth as it is only found in compounds like water, which covers over 80% of the earth's surface, and all living things, like plants & animals. A Hydrogen FuelCell uses the energy in hydrogen and oxygen molecules to make electricity.

It takes some energy to produce pure hydrogen because it requires molecular bonds to be broken. The process of separating chemically bonded elements is called electrolysis. The electrolysis of water (H2O) produces hydrogen which we can use in fuelcells. Two molecules of water can be separated into oxygen (O2) and two hydrogen molecules (2H2).

     2H2O + Energy > 2H2 + O2

Many fuelcells are known as reversible fuelcells because they can be used to electrolyze water (producing hydrogen and oxygen), and they can also be used to consume hydrogen and oxygen and produce energy (electricity). So the reverse equation is also carried out in a fuelcell: 2H2 + O2 > 2H2O + Energy

In this way, fuel cells serve a similar function to batteries, but do not confuse the two! A fuelcell consumes an outside fuel source (H2), which is replenished from any supply that produces pure H2 from outside the cell. As long as there is a supply of fuel (H2), the fuel cell never runs out of energy. Batteries, on the other hand, store electrical energy within a closed system and must be recharged periodically. When pure hydrogen is consumed in the fuelcell, the result is electricity and water with none of the toxic emissions of other fuel sources. The electricity created by fuelcells can be used in any application that uses electricity.

And beyond transportation, fuelcells are also being used for heating and power generation for homes, offices, communities, and even space stations with no pollution! (picture on right is of the 2009, 8 Hydrogen Car Tour in Olympia, WA. Robert drove the red one shown below. Quiet as a whisper, all electric hydrogen fuelcell engine and no tailpipe.)

hydrogencartour060109-olympia-wa3One big advantage of hydrogen fuel is that it can be stored and transported just as easy as natural gas, and in many applications even replace it using the same pipelines we have coming into our homes and businesses today. Our appliances don't care as long as it's fuel that will burn with some minor fitting adjustments. But the home or business will see an immediate improvement in cleaner air, more even heating, and no toxic fumes. Fortunately, we can use the enormous clean energy sources like wind and solar to produce the hydrogen creating a clean, transportable source of electricity and fuel with no hazardous emissions!  And with the Grothe Power Tower energy storage solution, that electrical energy and fuel (and clean water) can now be supplied right where the demands are, when there is no sun or wind 24 hrs a day, making for a complete renewable, sustainable, clean energy cycle from production to delivery, to end consumer with multiple uses for the local home, office, church, school, hospital, government building, community shopping center, or transportation car, truck, suv, bus & construction vehicles of all kinds. All within a local community economy, easy to distribute, cost effective, sustainable, and best of all pollution free. Will not hurt the environment ever! Now that's a good deal for everyone.
