The ZEG – technology (ZEG®)High efficient co-production of electricity and hydrogen fromhydrocarbon gases with integrated CO2- capture
• Electricity produced by high temperature solid oxide fuel cells (SOFC)
• Hydrogen production by sorption enhanced reforming (SER) using waste heat from the SOFC
• CO2 removed by a high temperature CaO-based sorbent in a carbonation reaction
• Close thermal integration in order to get overall high efficiency
• 2008: Basic technology elements (SER and SOFC) verified in 2 kW lab scale
• 2010: Technical economical feasibility studies, system design and modelling
• 2014: A 50kW pilot plant using biogas fuels (BioZEG) operational
• 2016: Design-engineering and cost estimation, upscaling from 50 kW to 400 kW

SER, advantages compared to SMR
Advantages• Higher H2-yields (95+ vol%), at lower
temperature (600-650°C)
• No need for shift catalysts
• CO2 capture included
• Simplified process layout and process intensification
Performance• Potential for lower production costs and
energy savings
• 70% efficiency

Pilot testing results - BioZEG50, Hynor Lillestrøm
• Established operational knowledge• Flexibility of process; supply of biogas,
hydrogen, steam and air• Control systems; start up, close down, operation,
data logs• Technical infrastructure, SHE
• Hydrogen produced
• Power produced to grid
• Thermal integration tested/verified• Sorbent is regenerated and CO2 released
• System modelling and optimisation• Existing models are calibrated with real
operational data

• CO2-sorbents; – Improved capacity– Improved stability– Increased lifetime
Next step – biogas to hydrogen demonstration plant
The BioZEG – value propositionBiogas is a product from waste management!
• Locally produced hydrogen used for transportation purposes, either/or
• Process improvements and modification:– Increased methane yield and reduced amount of CO2 by adding
hydrogen to the digester
– Avoiding separate CO2-scrubbing for production of biomethane. Raw biogas can be used for SER hydrogen production
• Scalable solutions for integrated industrial use, such as hydrogen used in biorefineries for production of liquid biofuels and CO2 for greenhouse purposes
• BioZEG gives the possibility of carbon negative energy solutions if CO2 is used or stored
