The pair aims to progress the development of the Estonian company’s systems in applications involving waste heat recovery.

Under the memorandum of understanding signed at the India Energy Week in Goa, JNK could provide engineering, procurement, and construction services to Elcogen, which is looking to strengthen its presence in the Indian market.

The partnership would initially target heat-rich, hard-to-abate sectors, including green ammonia, green urea, e-fuels, and power-to-x applications, which often create ideal conditions for solid electrolyser cell integration.

This comes after Elcogen appointed a business development director for India and the Asia-Pacific (APAC) region in January.

Elcogen’s solid oxide stacks for electrolyser systems (SOEC) produce syngas or hydrogen from water and CO2, while its solid oxide stacks for fuel cell systems (SOFC) can run on natural gas, biogas, or hydrogen.

Elcogen CEO, Enn Õunpuu, praised the agreement’s potential to improve the firm’s understanding of the Indian energy sector, which he said is “moving forward quickly”.

Solid oxide systems are well-suited to waste heat integration due to their high operating temperatures. However, with no large-scale systems operating globally, the technology remains relatively nascent. .

In September 2025, Elcogen boosted its SOEC and SOEF capacity to 360MW with a new manufacturing facility in Tallinn, backed by €25m ($29.6m) of support from the EU Innovation Fund.
