Tiaano offers hydrogen generation systems (electrolysers) that convert water (often deionized or purified) into hydrogen and oxygen via electrolysis. These are designed for high-purity hydrogen output, durability, and integration into green energy applications.
Here are the main features highlighted by Tiaano for their hydrogen electrolyser / generator units:

Purity of output: The PEM electrolyser version produces hydrogen of ≥ 99.99% purity.

Water requirement: Operates with deionized (or purified) water. Minimal impurities are desirable for longevity and performance.

Electrode / cell materials:  Titanium‐based electrolyzer designs. The anodes, cathodes etc. are made of titanium or nickel alloy substrates. Use of precious metal catalytic materials (e.g. mixed oxides) is implied for enhanced catalytic activity.

Design & Build: Skid‐mounted/cell assembly format; durable design to withstand continuous operation.

Applications: Suitable for industrial uses, green hydrogen projects, filling stations, hydrogenation, possibly for integration in renewable energy systems.

While full specs are not publicly disclosed in all cases, here are some of the known or implied specifications:

• Stack size / capacity: One of the units (non PEM) is listed approx. US$ 4000; this likely corresponds to a smaller scale generator.
• Electrolyzer stack: A PEM electrolyzer stack of size 25 cm² has been tested, indicating lab/small prototype scale.
• Production capacity mention: A model with 20 Nm³/hr Anion Exchange Water Electrolyser (AWE) capacity has been announced.
• Expected life / durability: Titanium & nickel alloy materials suggest good resistance to corrosion and long service life, but no explicit lifetime was found (for PEM units) in the sources I saw.

• High purity hydrogen – suitable for many industrial or clean energy needs.
• Robust materials – use of titanium, nickel alloys etc. improves durability,  corrosion resistance.
• Scalable – multiple models and sizes, indication of capacity up to 20 Nm³/hr, possibly more.
• Indian made – local manufacturing, which may help with pricing, service and customization in India.
• Green credentials – suited for renewable energy / zero emission applications.

To give a fair assessment, these are some of the potential challenges/areas where more data is needed:
• Energy efficiency:   Data on power consumption per unit hydrogen (e.g. kWh per Nm³ H₂) is not clearly published for many models. For buyers this is critical.
• Operating cost:   Aside from electricity, maintenance, water purity, and   replacement of catalyst/anode materials will influence cost of ownership.
• Scale & certification:   For large industrial scale or for fuel cell / transport uses, certifications, safety standards, and infrastructure integration will matter.
• Support, service & spare parts: As with any electrolyser, long‐term support, availability of consumables (electrodes, membranes etc.), and preventive maintenance is important.

Here are some likely applications where Tiaano’s electrolyser/generator would be well suited:
• Hydrogen production for fuel cell systems (stationary or mobile).
• On‐site hydrogen for industrial processes (e.g. hydrogenation, reduction, refining).
• Hydrogen filling stations or supply for vehicle fleets.
• Integration with solar/wind energy to store surplus electricity hydrogen (green hydrogen).
• Scientific / laboratory use (small stacks) or pilot projects.
