The Nanoptek SHG300 is a hydrogen generator panel that uses sunlight and Nanoptek’s patented engineered band-gap photocatalyst to reduce the electrical power needed to split hydrogen from water to as little as 1/3 of that required by PEM or ½ of alkaline electrolyzers, with an electrical energy basis conversion efficiency of 103% to as much as 148%.
Install the SHG300 panels for on-site hydrogen feedstock supply for chemical manufacturing, or industrial processes such as semiconductor or glass manufacture. The SHG300 can also enable efficient electrical energy storage (EES) for utility peak-shaving, remote telecomm back-up, or buffering of intermittent renewable power. Together with photovoltaic (PV) or wind power, the SHG300 panels can produce hydrogen even in remote off-grid off-pipeline areas, or supply refueling stations for hydrogen vehicles, all without any carbon by-product.
When the sun is not shining, the SHG300 can use grid or non-solar renewables such as wind to continue to produce hydrogen with its hybrid integral MMO (mixed metal oxide) titanium anode with conversion efficiency equal to that of many PEM electrolyzers, for 24/7 operation, stable hydrogen supply, and excellent return on investment.
While of course no carbon is produced with renewable power input, the efficiency of the sunlit SHG300 panels reduces even the carbon from fossil-fueled grid power input 50% to 66% per unit of hydrogen produced compared to alkaline and PEM electrolyzers respectively.
The SHG300’s highly efficient use of the shorter ultraviolet (UV) and blue wavelengths in sunlight means that it can continue to generate hydrogen at up to 1/3 or more of its peak capacity on most overcast days, because these energetic wavelengths penetrate cloud cover more effectively than the rest of sunlight.

The modular 2.0m2 panel form-factor is easily interconnected to scale from commercial roof-top to multi-acre field installations, or down to even a single unit for off-grid backup. It stacks flat for economical warehousing and shipping. Optimum shallow-angle mounting means the panels can be packed more densely in fields or on roofs. SHG300 Product Literature (PDF)
