BARC offers Alkaline Water Electrolyser technology for Rs 10 lakh plus 2% royalty

Bhabha Atomic Research Centre is offering alkaline water electrolyser plant technology for a technology fee of Rs 10 lakhs ($13,600) plus a royalty of 2 percent. 

The machine is of a design that can produce on-demand, on-site production of hydrogen and oxygen at a capacity of 10 Nm3/hr Hydrogen and 5 Nm3/hr Oxygen.

The alkaline water electrolyser plant consist of a compact, zero gap, bipolar type configuration cell module stack with high current density porous nickel electrodes. The product gases at the stack exit are conditioned and purified to meet the specific user demands. Demineralised water, electricity and chilled water are the only inputs required for the operation of this plant. The plant is capable of producing high quality hydrogen and oxygen gases and has yielded good performance in sustained long duration operations. The process can be easily scaled up or scaled down to suit the user requirements, BARC says.

Further details can be had from BARC website, linked above.

However, one wonders if there would be any takers for alkaline electrolysers, given that PEM is much better in terms of energy efficiency. 



Reliance, Tata Steel, L&T in talks with NCL for AEM electrolyser technology


At least three large industrial groups, Reliance, Tatas (Tata Steel) and L&T, are in talks with the Pune-based National Chemical Laboratories, for access to NCL's AEM electrolyser technology.

Dr Kaliaperumal Selvaraj, a senior scientist at the government of India-owned CSIR-NCL has been quoted by the Business Line newspaper as saying that his team has achieved success with a small scale AEM, using transition metals as electrodes. 

It is reliably learnt that NCL's AEM has successfully run for "a few thousand hours of continuous operation".

In another report, NCL's Director, Dr Ashish Lele, has been quoted as saying that green hydrogen at $ 2 per kg is possible.

As hydrogen insiders know, the 'alkaline' technology is the technology of yesterday; PEM is the technology of today; AEM is the technology of tomorrow. (Well, 'tomorrow' is at least 5 years away.)
