Summary: Biomass power generation technologies, now mature and competitive, can solve power shortages, mitigate environmental impacts of coal-based power generation, and offer renewable alternatives. This study employs patent data to reveal the technological evolution of biomass power generation. Growth curve and citation network approaches identify core technologies and main trajectories. Simulation and prediction based on the logistic growth curve suggest that biomass power generation has reached maturity and will saturate by 2031. Main path analysis traces technological trajectory, with patent citation analysis identifying six main technology paths. Further analysis highlights biomass power generation hybridization, waste-to-power utilization, and bioenergy with carbon capture and storage as potential technologies for achieving negative emissions.

Summary: Biological hydrogen production is a clean, renewable, and potentially sustainable way to generate energy. Dark and photo fermentations are considered more sustainable and economical, but they have limitations such as low yield and production rate. Integrating dark and photo fermentation, using lignocellulosic biomass, may improve and accelerate biohydrogen production technology sustainably.

Summary: Photo nanocatalyst play a promising role in various fields, especially in biohydrogen production, where their catalytic efficiency depends on size, surface-to-volume ratio, and number of surface atoms. They can utilize solar light to generate electron-hole pairs, which is crucial for their catalytic efficiency and requires appropriate excitation wavelength, band energy, and crystal imperfections. This review discusses the role of photo nanocatalysts in catalyzing biohydrogen production. It highlights the large bandgap and high defect concentration of photo nanocatalysts, allowing customization of their characteristics. The mechanism of photo nanocatalysts in catalyzing biohydrogen production is explored, and limiting factors are addressed, along with recommendations to enhance the utilization of these photo nanocatalysts in photo-fermentative biohydrogen production from biomass wastes.

Summary: Recent years have witnessed an increase in soil environmental problems, but the direction of research and development (R&D) for soil pollution remediation technology (SPRT) to address these challenges remains unclear. This study examines the status and future direction of SPRT through the analysis of 14,475 patents from 1971 to 2020. It is found that the United States, Japan, and South Korea hold a monopoly in SPRT, and patent organizations play a crucial role in technology transfer. The study identifies the need for more research on microbial-assisted phytoremediation technology, as well as green and cost-effective solutions for reducing organic pollutants in soil remediation.
