Combined Decarbonization of Electrical Energy Generation and Production of Synthetic Fuels by Renewable Energies and Fossil Fuels

Abstract

Power generation from renewable energy sources and fossil fuels are integrated into one system. A combination of technologies in the form of a carbon capture utilization (CCU)‐combined power station is proposed. The technology is based on energy generation from fossil fuels by a coal power plant with CO2 recovery from exhaust gases, and pyrolysis of natural gas to hydrogen and carbon, completed by reverse water‐gas shift for the conversion of CO2 to CO, which will react with hydrogen in a Fischer‐Tropsch synthesis for synthetic diesel. The carbon from the pyrolysis can replace other fossil carbon or can be sequestered. This technology offers significant CO2 savings compared to the current state of technology and makes an environmentally friendly use of fossil fuels for electricity and fuel sectors possible.

Liquid–Liquid Phase Behavior of Diesel/Biofuel Blends: Ternary Mixtures of n-Hexadecane, 2,2,4,4,6,8,8-Heptamethylnonane, and Ethanol and the Binary Subsystems

“…For this purpose, it is useful to study simplified surrogate fuels with well-known chemical compositions. Ternary mixtures of alkanes, their isomers, and short-chain alcohols, such as ethanol, propan-1-ol, butan-1-ol etc., became prominent model systems for the development of such surrogate fuels. − Since some years, the so-called decarbonization of commonly used fossil fuels has induced an increasing demand for research in the field of classical petrochemistry. − Reliable thermophysical data of fuels are needed for the basic understanding of chemistry and thermodynamics behind all processes dealing with classical engine combustion. , Due to the high complexity of the chemical reactions behind such processes, suitable model fuels or model systems have to be studied. The usually technical grade fuels and chemicals used, e.g., for self-ignition engines, make the proper characterization of the underlying processes difficult or even impossible. − Therefore, the development of suitable model fuels based on highly defined substances and mixtures is required: (a) for the purpose of standardization, (b) to guaranty high repeatability, and (c) to compare technical grade substances or mixtures with such reference systems. , In the case of diesel engines, the cetane number (CN) has been introduced to rate fuels of different origins.…”

Transformation of struvite from wastewater to a hydrogen fuel storage compound ammonia borane

“…The recycled nutrients from wastewater can also be directed towards other purposes such as making energy storage molecules in the energy industry. An increase in energy demand and consumption, along with a desire to reduce fossil fuel utilization, creates a demand for finding ways to transition to more carbon free and renewable energy sources (Veziroglu, 2007;Maaß and Möckel, 2019). The new sources should be eco-friendly and must also be sustainable, abundant, and have high energy density.…”
