Why GreenEd HS?
An overwhelming number of scientists, agree that the adoption of renewable energy will improve the efficiency and capacity of power grids. How does this benefit you? Using renewables as an alternative to fossil fuels alleviates climate change, reduces pollution, and curtails environmental degradation benefiting you and the global ecosystem. However, when renewable energy is not in use, it must be stored. Many people have heard of various types of renewable energy technologies (solar, wind, geothermal, biofuels, etc) and some may even know how they work. However, they have never heard of alternative energy storage methods such as hydrogen and fuel cells.
The Importance of GreenEd HS
Hydrogen gas, H2, is the lightest and smallest element of the periodic table and the most abundant in the universe. On Earth, we can use electricity via an electrolyzer to produce H2, then pass it through a fuel cell to generate the electricity again which is an excellent way to store unused energy. Unfortunately, 95% of hydrogen is “gray” produced from Steam-Methane Reforming and less than 1% is “green” produced from electricity from renewables. The H2-fuel cell system’s advantage over the battery is that hydrogen’s energy density is much higher (120 MJ/kg) than a typical battery's, which means you can store more energy using less mass. There is no hydrogen economy yet, due to a lack of infrastructure and only about 40 hydrogen fueling stations exist in the U.S. Nonetheless, the electrolyzer is the first step to create a hydrogen economy.
The GreenEd Mini-Electrolyzer
The GreenEd Mini-Electrolyzer is our flagship product. H2 and O2 flow rate, temperature, and supply voltage data can be easily read from the screen underneath the logo. The dial can be turned to control the amount of current allowed into the water tank. There is a 2.8 W monocrystalline solar cell within the top of a GreenEd unit which can be attached to the 6 V rechargeable battery pack for charging. For more hydrogen and oxygen production, the optional wall outlet can provide 24 V.The solar cell will likely not charge the entire pack, but it's there to understand that the energy for green hydrogen comes from renewable sources.
Who Is GreenEd For?
-
Engineers and Scientists - they need a cheap solution to obtain hydrogen and oxygen for their experiments and take quick measurements , such as attaching the hydrogen and oxygen output tubes to a fuel cell to test it.
-
Science Educators - will want an intuitive science kit, a teaching tool for students at a low pric
-
We are planning on selling each GreenEd unit for $300 which is much cheaper than conventional laboratory electrolyzers which cost more than $1,500. The $300 price is more affordable to ordinary teachers, engineers, and scientists, than the conventional electrolyzers.
What Is An Electrolyzer?
An electrolyzer is an electrochemical cell that splits water into hydrogen and oxygen using an electric current in a process called electrolysis. In an alkaline electrolyzer, there are two conductive electrodes, an anode and cathode are separated and emerged in an aqueous alkaline solution (H2O + NaOH) as known as the electrolyte. Sodium hydroxide, NaOH, dissociates into Na+ OH- ions in the electrolyte which allows the current to flow. Redox reactions occur at each electrode as a current is passed through them which produces hydrogen, H2 and oxygen gas, O2. The gasses are then each passed through a tube which is filled with a desiccant to remove the moisture from the gas stream. H2 and O2 then can pass through two gas ports located on the left side which can then be hooked up to a fuel cell to generate electricity. Go to the Department of Energy for More.
