2 1. Project achievements Solar Steam Reforming - Partnership Seven participants from seven countries aptlab apt AB CERTH/CPERI Germany Greece Italy The Netherlands Israel Switzerland United Kingdom

3 1. Project achievements Project main objectives Develop an advanced 400 kw th solar reformer Investigate various catalyst systems Simulate mass and heat transport and reaction in porous absorber Perform thermodynamic and thermochemical analyses to support the system design phase Operate the reformer with gas mixtures which represent the variety of possible feedstock on the solar tower at WIS, Israel, producing partly-solar hydrogen

4 1. Project achievements Project main objectives Evaluate new operation strategies Pre-design of a 1 MW th prototype plant Conceptual layout of a commercial 50 MW th reforming plant Assess on potential markets including cost estimation and environmental, socio-economic, and institutional impacts

5 1. Project achievements Milestones WP 1: WP 2: WP 3: WP 4: WP 5: date: 04/04 03/06 12/07 05/08 12/08 Catalytic system Reformer Solar Operation Pre-design of prototype plant Studies start of the project absorber segments reformer testing: start end pre-design strategy end of the project Note: Due to problems during the manufacturing of the reformer, the projectp is delayed. A duration extension of about one year is expected already included above.

6 1. Project achievements Catalyst development Progress Noble metal content of the final selected catalyst system could be reduced by 80% in comparison to the SOLASYS catalyst. Highly active for steam reforming and highly absorptive for concentrated solar energy.

7 1. Project achievements Progress insulation vessel window front flange extension distributor gas collector outlet gas channel inlet main absorber absorber inlet Reformer (400kW th, 10 bars, 900 C) Different concepts have been investigated. Mass of front flange was reduced by 40%. The mass flow through the absorber is regulated. Metal components and the absorber are manufactured and the final assembling will take place until the end of 2007.

8 1. Project achievements Progress Area in km² Solar Potential Algeria within 50 km of gas pipeline Market potential DNI in kwh/m²/y In Algeria about 72,000TWh/y can be used for solar H 2 production! (yellow and red area, along existing NG-pipelines) That is more than enough to produce today s H 2 amount (worldwide) completely in a renewable way!

9 2. Alignment to IP Implementation H 2 -production via reforming using concentrated solar energy Partly solar H 2 Production costs of less than 14 /GJ H2 or 1.7 /kg H 2 (large scale, solar-only) are possible. Carbon-dioxide-lean or neutral depending on the methane source (NG, biogas, etc.) w/o CO 2 sequestration Catalyst development for solar reforming highly active good absorptivity of the concentrated solar radiation cost effective

10 The process heat provided by combustion of fossil fuels in the conventional case can be provided completely by concentrated solar energy using solar-thermal concentrating systems. Saving of (fossil) fuels up to 38% (based on LHV and reforming efficiency of 75%), because fossil fuels can be used up to 100% only for chemical issues. Note: The savings are higher when CCS is applied! - High level policy objective regarding security of energy supply Reduction of CO 2 -Emissions. 2. Alignment to IP SOLREF Motivation Why solar steam reforming? - High level policy objective regarding reduction of GHG emissions

11 2. Alignment to IP IDA 2 Portfolio of Actions Suggestion: Include Solar Reforming! Transition processes partly renewable H 2 from e.g. solar steam reforming applied research pilot plant first commercial plant - few MWs CO 2 -free processes renewable H 2 from e.g. solar thermochemical cycles or solar HT steam electrolysis basic research lesson learned applied research lesson learned pilot plant lesson learned first commercial plant - few MWs It is the most convenient way to start today the renewable H 2 society Inexpensive in comparison to renewable H 2 Precursor for the scaling-up of CO 2 -free processes such as solar thermo-chemical-cycles

13 3. Cross-cutting issues Communication Education: Students, PhD students Dissemination: Installation of a project website. Publications in scientific and popular press Presenting scientific results at conferences Organisation of media events and workshops/colloquium Participation at trade fairs

14 4. Enhancing cooperation and future perspectives Cooperation Cooperation on EU-level and international level existed/exists. E.g. with INNOHYP CA, HySafe NoE and SolarPACES. Informal network exists with Japan and Australia with the aim to realise common projects.

15 4. Enhancing cooperation and future perspectives Cooperation Potential interactions with projects or organisations in the field of development of innovative reformers using concentrated solar energy as process heat in only-solar or hybrid mode.
