Technical Forum, Hannover April 27, 2017

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
