Abstract

The deployment of CO2 capture and storage (CCS) and negative emissions technologies (NETs) are crucial to meet the net-zero target by year 2050, as emphasised by the Glasgow Climate Pact. Over the years, several energy planning models have been developed to address the temporal aspects of carbon management. However, limited works have incorporated CCS and NETs for bottom-up energy planning at the individual plant scale, which is considered in this work. The novel formulation is implemented in an open-source energy system software that has been developed in this work for optimal decarbonisation planning. The DECarbonation Options Optimisation (DECO2) software considers multiperiod energy planning with a superstructural model and was developed in Python with an integrated user interface in Microsoft Excel. The software application is demonstrated with two scenarios that differ in terms of the availabilities of mitigation technologies. Results demonstrated the potential of fuel substitutions for low-carbon alternatives in existing coal and natural gas power plants. Additionally, once NETs are mature and are available for commercial deployment, their deployment is crucial in aiding CO2 removal in minimal investment costs scenarios. Overall, the newly developed open-source software demonstrates the importance of determining the optimal deployment of mitigation technologies in meeting climate change targets for each period.

Abstract

This article examines the use of exhaust-gas recirculation in milk powder production to optimize energy consumption and reduce costs. The dairy processing industry is known for its high energy usage and carbon emissions, and milk powder processing is particularly energy-intensive. The authors present an optimization model that identifies the most efficient recycle ratios to minimize utility use and estimated costs. The article includes a detailed process description and a case study comparing different exhaust-gas recirculation scenarios. The study highlights the potential benefits of energy optimization in the dairy industry, but also acknowledges the challenges of fines in the exhaust air and the cost of implementing wet scrubbers.
