The capture technology involved consists of the oxy-fueled Zero Emission Power Plant (ZEPP)-concept, based on combustion of low-calorific fuel (e.g. blast furnace gas) with pure oxygen in a specially designed gas combustor; in fact it is a downscaled rocket engine. Construction and testing of this highly innovative gas system has since 2008 been initiated and at a test site in California. The 170 MWth demonstation installation is available for shipment to IJmond at the end of 2009, ready for first operations in the course of 2010.

In Phase 1 of the project a two-year demonstration period is planned. A total CO2-production could be reached of up to 0,7 megaton per year (at full time operations). At a commercial scale, i.e. Phase 2, the power plant desgn wil be standardised into 200 MWe units with estimated max. capture capacity of up to 2,5 megatons per year, depending on the fuel type chosen (e.g. blast furnace gas or likewise). As such it is intended to construct a 400 or 800 MW power plant, with expansion options to 1.200 MW total in the future.

For Phase 2 CO2 storage is planned towards depleted gasfields offshore the Dutch Continental Shelf or transport to oil fields for use as EOR (Enhanced Oil Recovery).

When successfully tested the ZEPP-process could be applied in the power sector as well in the world wide steel industry.
