The Institute for Sustainable Process Technology (ISPT) at its energy and chemical industry partners have recently successfully concluded a feasibility study 'Power to Ammonia'. This study researched how to convert the surplus in renewable energy from wind and sun into ammonia. Three business cases have been studied.
The study shows that the electrochemical production of ammonia from renewable energy is a likely option to balance supply and demand of energy. "The great thing about this project is that it brings together all relevant parties," says Hans Wiltink of ISPT. "The renewable energy generated needs to be transported, converted into ammonia, stored, and finally used again as chemical feedstock or fuel for a power plant – it's a long chain, involving many different companies and new types of collaboration."
Ammonia as a chemical feedstock
Ruud Swarts, Technology Manager at OCI Nitrogen: "If we can use 'renewable' ammonia as the primary feedstock for our fertilizer and melamine production, we can significantly reduce our CO2 footprint. Electrolysis can currently not compete with conventional ammonia production. However, the Power to Ammonia study has shown that the technology could be competitive in 10 to 15 years' time, particularly if current trends such as increasing renewable electricity production and rising CO2 prices can be combined with innovative business models. Of course, there are still many hurdles to be overcome. By setting up pilots for this new technology, we can identify these and find ways to solve them."
Power to Ammonia is a partnership between ISPT, Stedin Infrastructure Services, Nuon, ECN, Delft University of Technology, University of Twente, Proton Ventures, OCI Nitrogen, CE Delft and Akzo Nobel.
