Vianen, Jop (author)While CO<sub>2</sub> is one of the factors increasing the global temperature, it is also utilized in the agriculture to enhance crop yield. In the agriculture, a sustainable solution to CO<sub>2</sub> mitigation would potentially lie in the greenhouses. A moisture swing direct air capture system can adsorb CO<sub>2</sub> from the air through...master thesis 2024

Reerink, Noa (author)Global warming is primarily driven by the emissions of carbon dioxide resulting from human activities. The construction industry, driven by urbanization and population growth, plays an important role in this due to its resource-intensive nature. Buildings account for nearly 40% of global energy consumption and one third of associated greenhouse...master thesis 2024

den Tonkelaar, Bram (author)To keep the global warming of the Earth to a minimum, the greenhouse gas emissions need to be reduced. Van Oord aims to be carbon neutral by 2050; therefore, Van Oord is exploring alternative fuels. Ammonia is a promising option to use as a fuel due to the forty times lower well-to-wake emissions than MGO when it is produced with green energy....master thesis 2023

Boon, Ricardo (author)Carbon dioxide can be used during concrete production, which leads to stronger concrete as well as a sequestration method for CO2. While these technologies are developed quite far, they are currently not being used within society nor is there any systemic overview of the system and a reason why these technologies are not used. This thesis...master thesis 2023
