Periodic Reporting for period 2 - MEMBER (Advanced MEMBranes and membrane assisted procEsses for pre- and post- combustion CO2 captuRe)
Reporting period: 2019-07-01 to 2020-12-31
MEMBER aims to demonstrate state-of-the-art capture technologies in an industrially relevant environment. To achieve this, MEMBER will scale-up and manufacture advanced materials and membranes and will prove their added value in terms of sustainability and performance under industrially relevant conditions (TRL 6) in novel membrane-based technologies. `
These new technologies will outperform current technologies for pre- and post-combustion CO2 capture in power plants as well as H2 generation with integrated CO2 capture and meet the targets of the European SET plan. In both cases, a significant decrease of the total cost of CO2 capture will be achieved. MEMBER targets CO2 capture technologies that separate >90% CO2 at a cost below 40€/ton for post combustion and below 30€/ton for pre-combustion and H2 production.
From the beginning of the project the main following actions have been done:
initial risks have been listed and solution to mitigate them proposed.
Value proposition of MEMBER technologies, including a preliminary identification of all the key exploitable results have been done.
Several business models related to different MEMBER technologies have been defined.
Go to market strategy has just started for all the previous defined business cases.
WP2 System requirements, design and modelling:
The system requirements have been defined and the different membrane modelling as well as the reactor and MMMs system modelling have been completed. The steps for the purification of hydrogen using metallic supported Pd-Ag membranes in a membrane module has been completed. The permeation behaviour of polymeric membranes was analysed including a sensitivity analysis to investigate the influence of feed concentration on the separation performance of the membranes. Studies on the prediction of permeation through mixed matrix membranes have been performed. The MA-SER model has been completed and improved. A thorough optimization on the pre- & post-combustion systems based on MMMs has been performed.
WP3 Core materials production scaling-up:
The MMMs raw material production scaling-up has been completed. ZIF-8 and ZIF-94 were chosen, and 1-kg batches of both MOFs have been produced. Pebax 2533 was chosen for use in the Prototype B. 50 kg of polymer has been produced. The investigation into the recycling of linkers and solvent in the MOF synthesis has been completed.
The sorbent has been optimised extensively. An initial sorption capacity of 0.25 g-CO2/g has been found to be optimum for the sorbent stability. Knowledge needed to produce the 200 kg batch for the prototype C has been generated.
Several catalyst formulations were synthesised and tested. Best performing catalyst was determined. The production of the 50 kg batch is underway.
Industrial scale design for MOFs production has been evaluated and proposed. Preliminary process flow diagrams for production have been completed. Estimates of CAPEX and OPEX for MOF production plants have been calculated including production cost of the final materials.
WP4 Membrane production scaling-up:
Main activities have been focused on the optimization of membrane production parameters, the scaling up of the membranes for the prototypes and the optimization of recycling procedure of the critical membrane materials. The PBI based MMMs HF spinning recipe for Prototype A has been optimised. Work is ongoing on the optimization of composite hollow fibre membrane preparation for the post-combustion CO2 capture prototype. Membranes for the MA-SER prototype have been produced (1.08 m2). The pilot plant revamping for recycling the Pd-based membranes has been completed and adjustments have been performed to optimize the recycling procedure.
WP5 Pilot prototypes design, construction & testing:
Within WP5 the partners are involved in the design and set-up of the three prototypes of MEMBER project plus the syngas cleaning system to be installed upstream the pre-combustion CO2 capture prototype, Prototype A. The other prototype systems are: Prototype B, a post-combustion carbon capture system and Prototype C, the MA-SER system for H2 production with integrated CO2 capture.
The detailed engineering of the three prototypes and the syngas cleaning has been finalised. The specifications for all components have been made, and mechanical designs have been made for those components not commercially available. 3D designs of the prototypes have been made. Using the specifications most of the components have been sourced and purchased. In the next phase construction will start.
WP6 Prototype demonstration:
WP7 Environmental LCA and economic assessment:
The elaboration of the screening environmental LCA and LCC has been completed. Data collection questionnaires were sent to the partners. Based on the data, models were built which describe the three MEMBER technologies as well as the key materials. In the last months, the models were refined and transferred to an industrial level for the MEMBER lines, the reference cases and the key materials. The results showed the importance of the feedstock and therefore of the influence of carbon capture on the plant efficiency in the reference systems, especially with regard to climate change impacts and use of resources.
WP8 Dissemination and communication:
The dissemination plan has been revised. Internal and external communication tools have been updated as well as communication material. MEMBER has been disseminated in social media. Up to now 25 contributions to various conferences have been made, 3 articles in scientific journals, one patent filled out and one thesis presented. A 1st public workshop on “Membrane processes for CO2 capture” was organised in January 15th, 2020. A second virtual workshop on “CO2 Capture and Utilization” was organised jointly to other 11 projects. The meeting took place in February 16th-17th, 2021.
WP9 Project Management:
The COVID-19 has strongly affected the activities of the project and several partners were not able to perform their tasks according to the planning. A tight follow-up of the COVID-19 impact has been implemented. Nowadays, the actual impact of the technical issues and of the COVID19 on the different activities have been assessed. It has been estimated that an extension of at least 6 months is needed to complete the activities of MEMBER.
- Prototype A, targeted for pre-combustion capture in power plants using MMMs.
- Prototype B targeted for post-combustion capture in power plants using MMM at the 8.8MW CHP facilities of Agroger (GALP, Portugal).
- Prototype C targeted for pure hydrogen production with integrated CO2 capture using MA-SER at the IFE-HyNor Hydrogen Technology Centre (Norway) under the supervision of ZEG POWER.
