Decarbonizing the transportation sector is critical to achieving global climate change mitigation. Although biofuels will play an important role in conventional gasoline and diesel applications, bioderived solutions are particularly important in jet fuels and lubricants, for which no other viable renewable alternatives exist. Producing compounds for jet fuel and lubricant base oil applications often requires upgrading fermentation products, such as alcohols and ketones, to reach the appropriate molecular-weight range. Ketones possess both electrophilic and nucleophilic functionality, which allows them to be used as building blocks similar to alkenes and aromatics in a petroleum refining complex. Here, we develop a method for selectively upgrading biomass-derived alkyl methyl ketones with > 95% yields into trimer condensates, which can then be hydrodeoxygenated in near-quantitative yields to give a new class of cycloalkane compounds. The basic chemistry developed here can be tailored for aviation fuels as well as lubricants by changing the production strategy. We also demonstrate that a sugarcane biorefinery could use natural synergies between various routes to produce a mixture of lubricant base oils and jet fuels that achieve net life-cycle greenhouse gas savings of up to 80%.


Solar irradiation on the rear surface of bifacial solar modules: a modeling approach
Durusoy, Beyza; ÖZDEN, TALAT; Akınoğlu, Bülent Gültekin (Springer Science and Business Media LLC, 2020-08-01)
The transition in the energy sector has started with the growing population leading to the growing energy demands. The use of photovoltaic (PV) technologies has become a crucial way to meet energy demand. There are many ongoing studies for increasing the efficiency of commercial PV modules. One way to increase the energy yield of the PV modules is to use bifacial solar panels by capturing the rear side illumination as well. One of the challenges for estimating the bifacial module performances is to calculat...
Dataset on the Marine Sustainability in the United Arab Emirates
Gülseven, Osman (Elsevier BV, 2020-08-01)
This data compiles the relevant indicators on measuring the UAE's attainments towards sustaining marine life and coastal ecosystems. Those indicators are compiled from three databases, namely from the United Nations, BertelsmannStiftung (BS) Foundation, and the Ocean Health Index (OHI). While the UN and BS indicators are widely accepted in measuring sustainability, many of the indicators in these databases are ambiguous and incomplete. The data from OHI is complete and offers a better perspective on measuri...
Simulating the effects of deep saline aquifer properties for CO2 sequestration
Basbug, B.; Gumrah, F.; Oz, B. (2007-10-01)
CO2 is one of the hazardous greenhouse gases causing significant changes to the environment. The sequestering of CO2 in a suitable geological media can be a feasible method to avoid the negative effects of CO2 emissions into the atmosphere. A numerical model was developed regarding CO2 sequestration in a deep saline aquifer. A compositional numerical model using CMG software (GEM) was employed to study the ability of the selected aquifer to accept and retain large quantities of CO2 injected in a supercritic...
Investment needs for climate change adaptation measures of electricity power plants in the EU
Lise, Wietze; van der Laan, Jeroen (2015-10-01)
Climate change is expected to have impacts on the power sector, leading to, among others, a need for adaptation measures in the sector in the near future. This paper analyses the need to adapt to climate change impacts for power generation technologies in Europe until 2100. Europe is broadly divided into four geographic climate zones, for which regional climate change impacts are quantified with the help of the ENSEMBLES RT2b data. The European future technology mix is based on two Eurelectric energy scenar...
Decarbonization of turkish public electricity sector: adopting sustainable energy portfolio
Şahin, Hasret; Soytaş, Uğur; Akınoğlu, Bülent Gültekin; Department of Earth System Science (2014)
Sustainable energy settles in the core of the economic activities since climate change issues have arisen. Decarbonization strategies of the electricity sector target to reach sustainable energy by liberalization movements. To adopt the sustainable energy portfolio similar to European Union ones’, Turkey took a step in decarbonization of the Turkish electricity sector by beginning with the public electricity sector. In this study, the decarbonization process of Turkish public electricity sector is projected...
