Summary: Solar photovoltaics have the potential to replace fossil fuels and contribute to lower-cost zero-emission energy systems. The initial benefits of providing solar power to the electricity system are significant, especially in deep decarbonization scenarios. However, the value of additional solar power decreases as cumulative solar capacities increase. Taking full advantage of low-cost solar energy requires the development and deployment of low-cost approaches to energy supply or electricity load shifting.

Summary: Developing new technologies for utilizing renewable energy resources is crucial for mitigating climate change and energy crises. Wave energy, as a renewable resource, offers higher power density and predictability compared to solar and wind energy. However, the technology for wave energy harvesting is still in its early stages. This paper proposes a novel Wave Net Power Assessment (WNPA) method that assesses wave resource potential from the perspective of Wave Energy Converters (WECs). The geospatial application of the WNPA method allows for the analysis of wave power production potential and provides valuable data for WEC developers to make informed decisions about deployment locations.

Summary: It has been suggested that using liquefied natural gas as a fuel source for heavy goods vehicles could lead to reduced greenhouse gas emissions. However, there has been little comparative analysis across various studies. This review provides a comprehensive examination of the well-to-wheel lifecycle emissions of liquefied natural gas for heavy goods vehicles in comparison to diesel. The primary factors affecting the emissions are the fuel efficiency of natural gas engines relative to diesel and methane leakage across the supply chain.

Summary: The COP26 Glasgow process led to stronger emissions reduction targets for 2030 and net-zero pledges for 2050-2070 by many countries. However, the impact on future warming remains uncertain. A study using four integrated assessment models (IAMs) analyzed national policies and pledges to assess CO2 emission trajectories in the near- and long-term, as well as their temperature implications. The results showed that the addition of long-term pledges can lead to emissions trajectories compatible with keeping warming well below 2 degrees C, but feasibility concerns exist regarding the cost of mitigation and deployment of technologies and measures.

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.
