CO2OLHEAT: supercritical CO2 power cycles demonstration in Operational environment Locally valorising industrial waste HEAT
CO2OLHEAT aims at demonstrating at TRL 7 the operation of a 2 MW Waste-Heat-to-Power (WH2P) system based on supercritical CO2 (sCO2) power cycle. This first-of-a-kind waste heat-sCO2 plant will be installed in the CEMEX cement manufacturing plant in Prachovice (CZ) and will valorize waste heat at 400°C contributing to the industry energy efficiency improvement and GHG emissions reduction. The project will analyze sCO2 WH2P potential from a technical, economic, and environmental point of view, as well as investigating CO2OLHEAT cycle benefits in the cement, glass, aluminum, and power generation sectors via replication feasibility studies.
The project is coordinated by ETN and it involves several EU industrial players (EDF, ENGIE, MYTH, CEMEX, SISECAM, CELSA) and key turbomachinery OEM (Siemens, Baker Hughes).
Project start: June 2021 | Project duration: 48 months

HIghly efficient POwer production by green Ammonia total oxidation in a membrane Reactor

The HiPowAR (HIghly efficient POwer production by green Ammonia total oxidation in a membrane Reactor) project aims at developing a power generation system that adopts a novel membrane reactor where ammonia is oxidized at high pressure using oxygen separated from air through the permeable membrane, without the need for air compression. The project focuses on a breakthrough in the direct conversion of ammonia into electricity, which is driving the acceptance of ammonia as a synthetic fuel without CO2 emissions. The membrane reactor is based on Mixed Ionic Electronic Conductor (MIEC) membranes and the plant can achieve higher efficiencies in electricity generation than internal combustion engines or steam generators.
Project start: September 2020 | Project duration: 48 months

Progetto H2020 LEILAC2: LOW EMISSIONS INTENSITY LIME AND CEMENT 2: DEMONSTRATION SCALE
C4U: Advanced Carbon Capture for steel industries integrated in CCUS Clusters

Funded by the European Union H2020 programme, C4U is a holistic interdisciplinary project addressing all the essential elements required for the optimal integration of CO2 capture in the iron and steel industry as part of the CCUS chain. This spans demonstration of two highly efficient solid based CO2 capture technologies for optimal integration into an iron and steel plant and detailed consideration of the safety, environmental, societal, policy and business aspects for successful incorporation into the North Sea Port CCUS industrial cluster in Belgium and the Netherlands.
C4U elevates from TRL5 to TRL7 two highly energy-efficient high-temperature solid-sorbent CO2 capture technologies for decarbonising blast furnace gas and other carbon containing gases. For the first time, in combination, these two technologies will target up to 90% of the total emissions from the steel plant that come from a variety of sources. In addition, C4U analyses the optimal design for full-scale integration of such technologies in industrial plants operated by the world’s largest iron and steel manufacturer, ArcelorMittal.
Project start date: 1 April 2020
Project expected end date: 31 March 2024

MACBETH – Membranes And Catalysts Beyond Economic and Technological Hurdles

The MACBETH poject (Membranes And Catalysts Beyond Economic and Technological Hurdles) was funded within the H2020 European research platform.
The project started in November 2019 and during its 54 months lifetime will validate industrial applicability of the Catalytic Membrane Reactor Technology through long-term operation of demo plants for the large-scale processes of hydroformylation, hydrogen production, and propane dehydrogenation at TRL 7. In addition, the consortium aims to achieve extension goals transferring this technology to biotech applications for the selective enzymatic cleavage of fatty acids and also to create a spin-off company ‘Lighthouse Catalytic Membrane Reactors’.

Social Energy research project
The Social Energy research project (co-funded by Regione Lombardia, CUP number: E59J18000000009, June 2017 – November 2019) focuses on the sustainable production of biomethane from the anaerobic digestion of chicken manure, agricultural residues and other types of residual biomass. The primary objective of the POLIMI team is to make the biogas-to-biomethane upgrading process energy self-sufficient and fully renewable by properly integrating energy technologies and optimized biogas upgrading processes.

SCARABEUS: Supercritical CARbon dioxide/Alternative fluids Blends for Efficiency Upgrade of Solar power plants

The aim of the SCARABEUS project is to demonstrate the capability of transcritical cycles, working with CO2-based binary mixtures in CSP plants, to reduce CAPEX (the target of the project is -30%) and OPEX (target -35%) with respect to state-of-the-art steam cycles, thus exceeding the reduction achievable with standard supercritical CO2 technology. This would translate into a LCOE below 96 €/MWh.
The partners of SCARABEUS will adapt the modelling of the cycle to CO2 mixtures with proper equations of states, along with the design of the heat exchangers and the turbomachinery involved. The partners will collect experimental data on various promising CO2 mixtures, and they will also demonstrate the innovative fluid and newly developed heat exchangers at a relevant scale (300 kWth) for 300 h in a CSP-like operating environment.
Project start: 1 April 2019
Project expected end: 31 March 2023
Partners: Politecnico di Milano, TU-WIEN, Universidad de Sevilla, City University of London, Università degli Studi di Brescia, Kelvion, Abengoa, Quantis
