Two scenarios were assumed to analyze the unit price of hydrogen implementation and build a blue hydrogen supply chain between Australia and Korea. Scenario 1 was the case of the unit price for transporting blue hydrogen produced at steam methane reforming (SMR) facilities in Australia to South Korea by three methods. Scenario 2 was the case of the unit price of hydrogen produced through domestic SMR facilities with CO 2 sequestration in Korea and Australia, respectively. Considering the various implementations and the unit price depending on the technology level and process efficiency, Monte Carlo simulation was used to calculate the implementation unit prices statistically. For scenario 1, the results were $12.4/kgH 2 (liquid hydrogen), $6.3/kgH 2 (ammonia), and $13.8/kgH 2 (liquid organic hydrogen carrier, LOHC). For scenario 2, they were $21.5/kgH 2 (Australia) and $13.7/kgH 2 (Korea), depending on CCS site location. This analysis showed that the implementation of blue hydrogen as ammonia in Australia is the most feasible option.

The increasing importance of addressing the climate crises through carbon neutrality is accelerating the transition to cleaner energy, such as in the case of electricity. This has led to a surge in demand for critical minerals, such as battery materials, that are essential for electrification, and rare earth elements (REE) that are essential for high-tech industries. Therefore, securing a stable supply chain of critical minerals is essential for a country's sustainable development. To build a foundation and database for exploration of critical minerals that do not have established ore genesis models and specialized exploration technologies yet, KIGAM has developed a mineral resources data platform that can increase exploration efficiency and share exploration data anywhere in the world, and its features are introduced here.

The direct current electrical resistivity survey or electrical resistivity tomography (ERT) is a geophysical exploration technique employed in various fields, including mineral exploration, environmental studies, and subsurface safety assessments. ERT, primarily conducted at the surface, can also be conducted between adjacent boreholes to yield high-resolution subsurface images at greater depths. Compared to surface exploration methods, cross-hole ERT employs distinct electrode configurations with varying sensitivities, making it crucial to consider these differences in electrode configuration or measurement environment conditions. This study elucidates electrode configurations and subsequently analyzes the characteristics of cross-hole ERT data for each electrode configuration. Following this, we explore the peculiarities stemming from borehole ERT data. We also describe distortions in ERT data caused by survey geometry and provide an examination of potential solutions to mitigate these distortions. Additionally, we introduce several case studies involving borehole ERTs.

This study analyzes carbon markets in the U.S. and Canada, including enhanced oil/gas recovery (EOR/EGR) projects. The American Carbon Registry (ACR), a voluntary carbon market in California, and the Canadian Alberta Emission Offset System have methodologies for EOR and storage in saline aquifers. ACR also presented EGR. EOR-CCS projects demonstrated significant CO2 reductions, ranging from 1,748 to 7,675 million tons in the U.S. and 30 to 3,040 million tons in Canada. The EOR and hydrogen-production-linked CCS projects are representative CCS projects in Canada. CCS infrastructure construction, R&D, and demonstration projects of oil/natural gas-CCS-hydrogen are actively underway in the net-zero policies by the U.S. and Canada. CCS projects in the U.S. and Canada, which are linked to the supply of natural gas and hydrogen energy in Korea, can secure new overseas energy sources and dispose of the CO2 captured in Korea.
本研究分析了美国和加拿大的碳市场，包括提高油气采收率(EOR/EGR)项目。美国碳登记(ACR)是加利福尼亚州的一个自愿碳市场，加拿大阿尔伯塔省排放抵消系统(Canadian Alberta Emission Offset System)拥有提高采收率和盐层储存的方法。ACR还提出了EGR。EOR-CCS项目显示出显著的二氧化碳减排效果，在美国减少了17.48亿吨至76.75亿吨，在加拿大减少了3000万吨至30.4亿吨。EOR和制氢相关的CCS项目是加拿大具有代表性的CCS项目。在美国和加拿大的净零政策下，CCS基础设施建设、研发和石油/天然气-CCS-氢气示范项目正在积极进行。与国内天然气和氢能源供应相关的美国和加拿大的CCS项目，不仅可以确保海外新能源，还可以处理国内收集的二氧化碳。

Tungsten is a resource that is widely used as a material for cemented carbide and special steel owing to its characteristics as a high-melting-point metal with excellent electrical and thermal conductivity, strong wear resistance and corrosion resistance, and low high-temperature thermal expansion coefficient. Demand is expected to increase as high-tech industries, such as robotics and aerospace engineering, develop in the current era of the Fourth Industrial Revolution. Tungsten minerals with economic development value are scheelite and wolframite, and approximately 73% exist in China, Austria, and Russia, while some are also buried in Sangdong mine, Korea. The interest in securing the resources and the processing technology development of tungsten should be constant, as the domestic supply is totally dependent on imports.
