Anaerobic digestion for energy generation and nutrient recycling in the City of Buenos Aires: A techno-economic and carbon footprint analysis

Organic waste is the largest domestic waste category in the City of Buenos Aires (CABA) and is currently landfilled together with other waste streams. Landfilling organic waste not only has a large impact on the environment, but also leads to the loss of the value embedded in organic waste, such as nutrients and energy. In this regard, anaerobic...

Front-End Techno-Economic and Environmental Analysis on CCU Technologies: Identifying the most business critical pathways for valorization and utilization of carbon dioxide

Carbon capture and utilization (CCU) is an emerging technology for reducing the CO2 concentration in the atmosphere and to limit the negative effects on the global warming. Different from carbon capture and storage (CCS), in CCU the carbon captured from point sources or direct from air is processed to valuable carbon containing products. Several...

Phosphorus recovery from dairy manure via biocrystallization in a UASB reactor: A techno-economic and environmental assessment

Recovering phosphorus from manure allows to cycle a valuable nutrient back to agriculture while offering farmers a way to comply with the increasingly restrictive legislation concerning livestock manure application on agricultural land. To this end, a novel biocrystallization process in an Upflow Anaerobic Sludge Bed (UASB) reactor has been...

Air-to-Methanol via the micro-plant approach: An ex-ante Life Cycle Assessment

The capture of carbon dioxide before or after it is emitted has been regarded as a crucial mitigation pathway to prevent the rapidly increasing accumulation of CO2 in the atmosphere. The valorisation of the captured CO2 into value added products such as methanol provides an additional economic incentive to continue developing these technologies....

Carbon capture and storage in industrial product value chain: An economic assessment of the impact of carbon capture and storage in the industrial product value chain: from industrial production to final product

This research provides insight into the implementation of CCS in industrial production from a consumer perspective (i.e., the cost impact on the final product). The impact of implementing CCS in two different industries (e.g., cement and steel) to produce a final product is analyzed. Also, this research provides insight into CCS implementation...

Long-Term Feedback Enabled Energy Management Control Framework for Ships with Hybrid Power Supply

In the present study, a Model Predictive Control (MPC) - based, Energy Management Strategy (EMS) is proposed, aiming at the minimisation of the fuel consumption of vessels with hybrid propulsion and power supply. This approach is capable of utilising online information regarding realistic future predictions of the propulsive power demand,...

Hybrid boiler systems in the Dutch industry: A techno-economic analysis of the potential of hybrid boiler systems to cost-effectively decarbonise steam generation in the Dutch industry

The Netherlands aims to accelerate the energy transition. Accordingly, ambitious targets have been set for the industrial sector. This will require additional investments in the Dutch industry which is expected to reduce the CO2 emissions at limited costs in comparison with other sectors. However, the ambition to reduce the emissions can create...

Electrochemical synthesis of CO2-methanol utilizing direct air capture, CO2 electrolysis and H2O electrolysis: A life cycle assessment

This thesis examines the production of an alternative liquid hydrocarbon fuel, namely CO2-methanol, produced utilising DAC, CO2 electrolysis, H2O electrolysis and thermo-catalytic synthesis. The reason for such research lies in a persistent growth in global energy demand, a significant share of which comes from liquid fuels, in the present...

The environmetal impact of a solar powered CO2 to methanol farm

Zero Emission Fuel (ZEF) has the goal to create affordable high-grade methanol, produced from absorbed carbon dioxide and water from the air. The methanol is produced in a solar methanol (MeOH) farm, consisting of 13225 micro-plants which are powered by PhotoVoltaicsolar panels (PV panels). The solar capacity of the solar MeOH farm is 12 MW and...

Power to methane to power: Performance analysis of a closed loop energy storage system

Reducing carbon emissions in the power generation sector can be done by generating energy from renewable sources such as wind and sun. However these sources alone cannot provide a reliable electricity system and therefore an energy storage system is needed. Power-to-gas is a concept in which surplus renewable electricity is used for the...

Uncertainty in electrified industrial systems: Towards a method for the identification and exploration of uncertain factors
