ROLINCAP will search, identify and test novel phase-change solvents, including aqueous and non-aqueous options, as well as phase-change packed bed and Rotating Packed Bed processes for post-combustion CO2 capture. These are high-potential technologies, still in their infancy, with initial evidence pointing to regeneration energy requirements below 2.0 GJ/ton CO2 and considerable reduction of the equipment size, several times compared to conventional processes . These goals will be approached through a holistic decision making framework consisting of methods for modeling and design that have the potential for real breakthroughs in CO2 capture research. The tools proposed in ROLINCAP will cover a vast space of solvent and process options going far beyond the capabilities of existing simulators. ROLINCAP follows a radically new path by proposing one predictive modelling framework, in the form of the SAFT-γ equation of state, for both physical and chemical equilibrium, for a wide range of phase behaviours and of molecular structures. The envisaged thermodynamic model will be used in optimization-based Computer-aided Molecular Design of phase-change solvents in order to identify options beyond the very few previously identified phase-change solvents. Advanced process design approaches will be used for the development of highly intensified Rotating Packed Bed processes. Phase-change solvents will be considered with respect to their economic and operability RPB process characteristics. The sustainability of both the new solvents and the packed-bed and RPB processes will be investigated considering holistic Life Cycle Assessment analysis and Safety Health and Environmental Hazard assessment. Selected phase-change solvents, new RPB column concepts and packing materials will be tested at TRL 4 and 5 pilot plants. Software in the form of a new SAFT-γ equation of state will be tested at TRL 5 in the gPROMS process simulator.

The COOL DH project will innovate, demonstrate, evaluate and disseminate technological solutions needed to exploit and utilise sources of very low-grade "waste" heat for heating of energy efficient buildings via Low Temperature District Heating (LTDH) and show how the District Heating (DH) systems can be more resource efficient and more energy efficient. The demonstration covers both new developments and stepwise transition of existing areas with district heating and energy retrofitting of buildings. The COOL DH consortium consists of the utilities and municipalities of the two cities Lund (SE) and Høje-Taastrup (DK) and leading DH energy specialists as well as leading industrial manufacturers. COOL DH will: - Innovate, design and build cooling and heat recovery process systems, enabling heat recovery to a local low- temperature district heating grid. They will mainly be driven by renewables. Design work will start in 2017 and heat recovery will start in 2019. - Design and build a low-temperature district heating grid with non-conventional pipe materials and testing of new innovative pipe components that will become new products introduced as a result of COOL DH. - Innovate and design suitable innovative heating systems and controls inside buildings that combine LTDH with distributed integration of local produced renewable energy on the buildings. Erection of new buildings in Lund will start in 2018 and will continue throughout the time of this project, while LTDH in Høje-Taastrup mainly will be for existing buildings being refurbished including modification of the heating system. - Develop viable business models and new pricing systems, that ensures a good (low) return temperature and provide the building companies with maximum flexibility regarding the choice of heating systems. - Demonstrate a full system with all needed components suitable for ultra-low DH temperatures (40 oC) incl. demonstration of systems for heating of DHW without risk of legionella.
