How to use solar panels to make hydrogen gas.

After the split hydrogen is sequestered and. 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. Scientists in belgium have invented a solar panel that produces hydrogen as a source of fuel to heat homes. 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.

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. 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. 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.

Using moisture in the atmosphere the solar panel converts sunlight into hydrogen gas. Moreover it has potential to remain in operation for a long time to come. The use of solar energy to produce hydrogen can be conducted by two processes. The anode side rips oxygen from water in a process called solar electrolysis and the cathode side produces the flow of hydrogen gas.

The most common methods for producing solar hydrogen employ either pecs or pv systems plus electrolyzers ec. 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. 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.
