KYIV, Oct 21 – The cost of a pilot hydrogen project of Naftogaz Ukrayiny and RWE Supply & Trading (Germany) for the production of green ammonia is tentatively estimated at EUR 500 million, head of Naftogaz Ukrayiny Yuriy Vitrenko said.

"We now estimate the cost of this project at approximately EUR 500 million. The economic effect of this project will significantly exceed the investment in it, but a lot depends on regulation, both in the European market and in Germany, because this entire green hydrogen industry is new, and even now there is no final decision by the German government how it will develop hydrogen energy in Germany, and the final profitability of the project depends on this," he said in an interview with DW.
