How To Use Solar Panels To Make Hydrogen Gas

A team at katholieke universiteit leuven or ku leuven says it has developed a solar panel that converts sunlight directly into hydrogen using moisture in the air.

How to use solar panels to make hydrogen gas. The 1 6 m 2 solar panel directly converts 15 of incident solar radiation into hydrogen. When considering solar generated electricity almost everyone talks about pv electrolysis. Using moisture in the atmosphere the solar panel converts sunlight into hydrogen gas. The use of solar energy to produce hydrogen can be conducted by two processes.

The prototype takes the water vapor and splits it into hydrogen and oxygen molecules. Scientists in belgium have invented a solar panel that produces hydrogen as a source of fuel to heat homes. Hydrogen powered cars may soon become more than just a novelty after a unsw led team of scientists demonstrated a much cheaper and sustainable way to create the hydrogen required to power them. Green energy would be boosted if excess electricity from wind and solar farms was used to produce hydrogen for use in heating and other parts of the energy system according to engineers.

Conventional solar panels boast solar to electricity conversion efficiencies in the 18 to 20 range but if the power produced is then applied to the electrolysis process for hydrogen evolution overall efficiency declines. According to yang for solar fuel cell cathodes we re already. The anode side rips oxygen from water in a process called solar electrolysis and the cathode side produces the flow of hydrogen gas. Moreover it has potential to remain in operation for a long time to come.

One way to make hydrogen using sunlight is to use a solar panel to make electricity and then use that electricity to power a commercial electrolyzer that splits water forming hydrogen and oxygen. It shows both high solar to fuel and solar to electric efficiencies works at unprecedented power and current densities and offers cost effective fuel and power. The device a dye sensitized photoelectrosynthesis cell generates hydrogen fuel by using the sun s energy to split water into its component parts.
