ASCENT (2014 – 2017) was a collaborative project under EU 7RP. The project addressed the need for new concepts that can reduce the energy demand associated with CO2 capture in power generation.
The project work was focused on pre-combustion technologies; CO2 capture using energy efficient high temperature solid sorbents for separation of CO2 by conversion of hydrocarbon gases into H2.

The project provided operational knowledge of the 50 kW BioZEG plant as well as key information on performance, durability and thermal integration. The obtained results will be used for optimization, upscaling and commercialization of the ZEG-technology.
The project provided important results for the optimization of the Sorption Enhanced Reforming Technology (SER) for hydrogen production from biogas. Particular focus was given to kinetic models for the particle systems (sorbent and catalyst) used in the process, as well as study of particle attrition and loss during continuous operation. The fluidized bed reactor system of Hynor Lillestrøm was used in the project.
Cost effective conversion of biomass to hydrogen and electric power for transportation purposes.During the project a 50 kW ZEG demonstration plant was developed and constructed at the Hynor Lillestrøm Hydrogen refueling station. By thermally integrating a 30 kWH2 SER (Sorption Enhanced Reforming) reactor system with a 20 kWel SOFC (Solid Oxide Fuel Cell) module utilizing biogas, a total efficiency of at least 70% will be demonstrated.The project was funded by Innovation Norway, Statoil ASA and ZEG Power AS.Obtained results in the BioZEG-project
Zero Emission Gas Power – Technology Qualification for Industrial Scale ZEG Plants.The main objectives of the project work was testing of «all-in-one» particles (combination of reforming catalysts and CO2-absorbents) for Hydrogen production, as well as next generation SOFC-stacks for ZEG plants.The project was funded by the CLIMIT-programme of The Research Council of Norway.Obtained results in the ZEGTech project
ZEG NYBORG; Hynor node Bergen. Layout and design of hydrogen production facilities and fueling stationThe main objective of this pre-project was to explore the possibility of establishing a hydrogen refueling station in the Bergen region utilizing local hydrogen production with CO2 capture based on ZEG-technology developed by Prototech and IFE.
Long-term testing of pilot plant at the Risavika Gas CentreThe ZEG-concept was demonstrated in a 2 kW laboratory installation at the Risavika Gas Centre (2005-2007). The main objective of the LongZEG project was to verify that the ZEG-technology was ready for demonstration in a pilot plant. The project was carried out by long-term testing of key technologies at conditions realistic for operation of such a plant.The project was funded by the CLIMIT-programme of The Research Council of Norway.
Co-production of electric power and hydrogen with integrated CO2 capture. A techno-economical feasibility study. System and cost optimization.The objective of the project work was to evaluate the technical and economic potential of the ZEG-technology when applied to large-scale natural gas-based plants. Different configurations were evaluated in the study: stand-alone electric power production (400MW), stand-alone hydrogen production (700MW), as well as other concepts with co-production of electric power (400MW) and hydrogen (50MW – 700MW).The project was funded by the CLIMIT-programme of The Research Council of Norway, and Statoil ASA.Parts of the results are published;Meyer et al 2011
Concept study of a 200kW demonstration plant for co-production of hydrogen and electric power with integrated CO2 capture.The main objective of the project was to develop a process design for a 200kW demonstration plant for co-production of hydrogen and electric power with integrated CO2 capture. In addition, objectives of the work were to:• Establish industrial interest for the realization of a 200kW demonstration plant
• Establish specifications for a 200kW demonstration plant

Technology for zero emission power plantsThe project dealt with new technologies for co-production of hydrogen and electric power with integrated CO2 capture, using natural gas.The main objective of the project was to establish knowledge and competence within key technology areas relevant for realizing a new type of high-efficiency zero emission power plants that will be able to deliver electric power and hydrogen at a competitive price.ZeroGen was a research and development project funded by the Klimatek-programme of The Research Council of Norway, and was conducted in collaboration between Institute for Energy Technology (IFE) and the CMR group.
Construction of verification unit, demonstration of co-production of electric power and hydrogen with integrated CO2 capture.The objective of the project was to build and test a 2kW power plant (co-production of hydrogen and electric power) based on the ZEG-concept and thus demonstrate the different key technologies together. This included a 1kW SOFC stack, a SE-SMR (Sorption Enhanced Steam Methane Reforming) reactor for conversion of natural gas to Hydrogen as well as CO2 capture, and room temperature IR measurements for analysis of the CO2 gas. The installation was constructed and tested at the Risavika Gas Centre.This was the first time the SOFC and SE-SMR reactor technology was integrated in the same installation, and the demonstration was an important step towards further up scaling. During the project, production of hydrogen with efficient CO2 capture was demonstrated, and produced hydrogen was used to operate the SOFC. The project work provided valuable operational experience.The project work was funded by the Klimatek-programme of The Research Council of Norway.
Future Energy Plants, co-production of Hydrogen and electricity with integrated CO2 captureThe project dealt with concept development for production of hydrogen and electric power with integrated CO2 capture using natural gas.The objective of the project was to develop a concept for next generation natural gas power plants producing hydrogen and electric power with integrated CO2 capture and a high total efficiency. The work provided a platform for further design and development of various alternative solutions to concretize the technology in demonstration plants of increasing complexity and size.The project work was conducted with funding from the Klimatek-programme of The Research Council of Norway in collaboration between Institute for Energy Technology (IFE), CMR Prototech and CMR Instrumentation.Obtained results in the ZEG-project (2001-2005)
