Summary: This research focuses on the optimal planning of microgrids by incorporating renewable energy sources and conventional units. A multi-objective model is used to consider economic factors and energy management, while accounting for limitations and different energy sources for a more realistic approach. The model takes into account the uncertainty in production capacity of wind turbines and photovoltaics, and incorporates load uncertainty, price, and renewable energy production. Through a demand response program with incentives, the model aims to maximize profitability and minimize costs. To solve the conflicting objectives, a developed optimization algorithm based on teaching-learning and fuzzy theory is proposed.

Summary: Utilization of CO2 for sustainable production of carbon-based chemicals can be achieved through the reverse water-gas-shift reaction. The fully electrified reverse water-gas-shift (eRWGS) process, using ohmic heating and a nickel-based catalyst, allows for the production of synthesis gas with high hydrogen and carbon efficiency. This emissions-free route provides a sustainable solution for the production of carbon-based chemicals from CO2 and renewable electricity.

Summary: The tragedy of overconsumption leading to the depletion of natural resources has had severe negative effects on both humanity and the environment. Unregulated and unscientific waste treatment has further worsened the situation, exacerbating ecological decay. To address this, there is a need to shift from a linear economic system to a circular one by focusing on recycling available resources at their maximum capacity. This paper examines the impact of a circular economy on CO2 emissions intensity among the top seven CO2 emitters in the world and finds a positive correlation between municipal waste, a crucial component of the circular economy, and CO2 emissions.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
