Aim. This study focuses on analyzing various approaches to transporting captured carbon dioxide (СО₂) to storage sites.

Methods. The study examines four transportation methods for moving СО₂ to storage sites: pipeline, water, rail, and road systems.

Results. Our analysis revealed the unique characteristics of transporting captured СО₂ in various phase states. We determined the quality characteristics of СО₂ affecting the durability of the materials used in transportation containers and systems. Additionally, we analyzed the features of existing pipelines specifically designed for СО₂ transportation. that the findings suggest that when designing carbon pipelines, it is essential to consider the physical, environmental, and social factors of the area where the pipeline will be located.

Conclusion. The analysis of methods for transporting captured СО₂ to storage sites indicates that pipeline and water transport systems are currently the most viable options. Transporting СО₂ by water shares several similarities with the transportation of liquefied petroleum gas. Conversely, rail and road СО₂ transportation tend to be more expensive compared to pipeline and water options and may be appropriate for smaller, geographically distributed emission point sources where temporary storage in containers is feasible.

This article focuses on bridges with beams of combined cross section made of glued wood and reinforced concrete. The main purpose of the study is to compare the key characteristics of reinforced concrete, glued wood, and combined bridges. The comparison is based on three main parameters: cost, operational lifespan, and load capacity. The innovation of the use of glued wood in the construction of bridges lies in a combination of the strength and elasticity of wood with the strength and durability of reinforced concrete, which allows you to create more stable and economical structures that can withstand heavy loads. An analysis of the main characteristics of these such bridges allows us to conclude that the advantages of such a combination of materials over other types of bridges. The data obtained can be useful for designers and builders when choosing optimal material for the construction of a bridge structure.

Aim. The aim of this study is to compare the performance of toroidal and solenoidal configurations of a superconducting inductive energy storage device using CORC® and racetrack cables made from high-temperature superconducting tapes.

Methods. A numerical multiphysics analysis of inductive energy storage device was performed using the finite element method in the Comsol Multiphysics engineering modeling environment.

Results. The analysis revealed that the CORC® cable in a solenoid configuration, with a transport current density to critical current density ratio of 0.7 at the boiling point of liquid nitrogen, was the most suitable for inductive energy storage.

Conclusion. The developed numerical model allows to calculate energy capacity and energy losses in superconducting inductive energy storage devices configured as solenoids or toroids. This model can be applied to the development of inductive storage devices made from HTS composites.

Background. St. Petersburg University of Architecture and Civil Engineering is developing alternative proposals creating a high-speed highway in the Arctic zone along the Northern Sea Route. This project includes stops at major transport and logistics centers along the country’s coast as part of research by future master builders. The Arctic Transport and Energy Highway originates in the Northwestern region of Russia, starting from the seaport of Ust–Luga. The routes passes through the Leningrad and Arkhangelsk regions, the Polar regions of European Russia, Siberia, Chukotka, and ends in Alaska via the Bering Strait, thereby connecting two continents. The structure of this highway includes an overhead power line with a voltage of 330 kV running along its entire length on common load-bearing structures. This line will connect to the main electric networks of the country, including the floating power plant Akademik Lomonosov in the port of Pevek. South of Gatchina in the Leningrad Region, a large Transport Interchange Hub is proposed, where an urban high-speed transportation highway from St. Petersburg will connect to the highway. The results of scientific research on the layout and architectural design of transportation hubs are presented.

Aim. The aim of this study is the development of a high-speed transport and energy highway in the Arctic zone, based on the widespread use of electric transportation.

Materials and Methods. The highway route was built, and trestle structures were designed to handle combinations of operating loads, forces and influences. These designs account for dynamic aspects and nonlinearity, using software such as SAP2000, SCAD Office, and Lira.

Results. Preliminary technical and economic indicators show that the duration of cargo delivery along the Arctic Expressway to the Bering Strait is reduced by 5.5 times compared to the Northern Sea Route, and passenger travel time is reduced by almost 30 times. However, the projected expressway is almost 1.6 times longer owing to the need to bypass high coastal mountain ranges.

Conclusion. These studies confirm the feasibility of using evacuated tube transportation and maglev technologies for the Arctic high-speed transportation highway. Future research will consider tunnel mining and underwater pipelines, which will allow for extended rectilinear sections exceeding 1000 km. This would reduce the total length of the Arctic transportation and energy highway, decrease transportation duration for passengers and cargo, and minimize the number of transportation hubs.
