Strategic collaboration Proton Ventures and Duiker Combustion Engineers

30 July 2019

Rotterdam, July 30 2019 – As of July 25th Proton Ventures BV and Duiker Combustion Engineers B.V. started a strategic collaboration. Companies will collaborate for, among other things, start-up of mini-ammonia plants in combination with the Stoichiometry Controlled Oxidation (SCO) technology developed by Duiker Combustion Engineers. S.C.O technology converts ammonia into high temperature heat.

Proton Ventures develops worldwide small-scale ammonia plants for conversion of wind and solar energy into ammonia. Duiker CE technology burns ammonia-rich streams in a furnace environment with very low NOx formation and without CO2 emissions. S.C.O. technology makes it possible to save fossil based energy and producing less CO2 and NOx emissions, because the ammonia containing fuels are oxidized in a controlled manner.

Hans Vrijenhoef, CEO Proton Ventures: “We like to collaborate with partners to complete the chain of using ammonia as an energy solution. This includes also power and heat generation and solutions for energy storage. The S.C.O. technology of Duiker CE opens new possibilities for us in applying local ammonia production from small to large scale, such as conversion of power plants to cleaner fuels while maintaining the existing installations. A combination of our expertise leads to this unique collaboration.”

Enter new markets

With this collaboration Duiker CE is also entering a new market. Currently, Duiker CE mainly operates in the (petro)chemical industry, where the S.C.O. technology has now proven itself technically and commercially. Albert Lanser, Duiker CE Business Development Director: “This collaboration offers us the opportunity to place our S.C.O. technology worldwide on the map in a completely different customer segment than we currently serve. Moreover, this S.C.O. technology is in combination with ‘green’ ammonia production unit capable of making a real contribution to the climate because ammonia does not emit CO2 during combustion. The collaboration with Proton Ventures, for example, has a reinforcing effect on the business proposition. After all, we can now offer the customer a total concept for making his / her heat demand or production process more sustainable.”
