Summary: The current context of the climate emergency calls for the decarbonization of the energy sector through the adoption of renewable energy sources. Concentrating solar power (CSP) technology has emerged as a commercially viable alternative, although it is hampered by high production costs and the challenge of managing production during temporary variations in solar resource availability. This study proposes the hybridization of CSP technology with direct biomass combustion, presenting an innovative process scheme that deviates from traditional configurations. The techno-economic evaluation of this novel configuration in a small-scale power plant reveals the potential for a cost-effective and sustainable energy solution.

Summary: This study presents a novel methodology to design and assess the performance of a micro-scale solar-only air-breathing open Brayton cycle. Different thermodynamic layouts are generated and evaluated under various solar irradiation levels. The use of PyCycle, a thermodynamic cycle modeling library, allows for jet engine performance modeling to be transformed into solar thermal plant performance modeling. The study also demonstrates the importance of the thermodynamic configuration on the off-design performance of the plant.

Summary: This paper investigates how a sustainable and durable electricity supply can be provided in off-grid communities in Colombia using a system dynamics model. The results show that transitioning from diesel to renewables is not only possible, but also economically viable and desirable. The simulations suggest that in order to make the best use of limited government funding, the transition to renewables should begin as soon as possible and be accompanied by a zero-diesel policy by 2040. Additionally, the model highlights the importance of designing electricity systems to enable gradual growth in demand driven by socio-economic development and productive uses.

Summary: The Bangladesh Solar Home Systems (SHS) programme, the world's largest domestic solar off-grid electrification scheme, is at risk of collapsing due to the decline in end user support and installation levels. Several factors, including the government's implementation of competing energy access projects, lack of regulatory oversight, and subsidy decreases, have led to customers abandoning the programme. This jeopardizes Bangladesh's objective of achieving Sustainable Development Goal (SDG) 7 by 2030.

Summary: Despite significant progress, the electrification sector in India still faces multiple challenges. This study examined the drivers and barriers to rural electrification, highlighting the importance of enabling policies and government support. The research identified political, economic, and financial factors as the main drivers for centralized grid expansion, and convergence with livelihood programs and electricity for irrigation as strong drivers for RE-based mini-grids. High electricity costs and customers' inability to pay were perceived as barriers for both central grid and mini-grids.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
