Please note: Nanoptek has replaced the SHG300 with an improved Hybrid Solar Hydrogen Generator. Serious inquiries will receive a detailed slide presentation upon request.

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, for an electrical energy basis conversion efficiency of up to 148%.

By providing efficient chemical storage of electrical energy, the SHG300, in combination with hydrogen storage and fuel cell components from other manufacturers, enables more efficient electrical energy storage (EES) and distributed electricity storage (DES). Utilities can save low-cost off-peak power to replace expensive peak-load capacity. Intermittent solar and wind power can be efficiently converted into hydrogen to provide a stable buffer to the grid, converting such clean sources into reliable “on demand” power to utilities.

When the sun is not shining, the SHG300 can continue to produce hydrogen with its integral MMO (mixed metal oxide) anode, chemically converting off-peak power from windfarms or the grid for later use, and with conversion efficiency as good as or better than many PEM electrolyzers.

Of course, no carbon is produced with renewable power input.  But even with fossil-fueled grid power input, the sunlit panels reduce carbon 50% to 66% per unit of hydrogen produced compared to other electrolyzers.

The SHG300’s highly efficient use of the shorter 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 up to utility-size multi-acre MW installations, or down to off-grid backup and commercial installations. 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.
