An internet data center (IDC) filled with server computers needs a huge cooling system, with its room temperature kept at about 19 degrees Celsius (66.2 degrees Fahrenheit) using air conditioners. An ordinary IDC uses about 30 percent of consumed electricity for cooling.
Cooling systems that utilize cold energy go through regasification processes that convert liquefied natural gas (LNG) at -162 degrees Celsius back to natural gas at atmospheric temperature. During regasification, heat is drawn from nearby objects to accelerate the process.
KT said in a statement on November 22 that when the LNG-based cooling system is developed, it will help a mid-sized data center to save 12 megawatt-hours of electricity every month, which is enough to power 30,000 ordinary households. Because the cold energy system uses almost zero electricity for cooling, it can be established in remote areas where the supply of electricity is limited.
"We hope this technology becomes the foundation for the next-generation carbon-free IDC technologies," KT's enterprise division director Shin Soo-jeong was quoted as saying.

Busan City Corporation to Officially Certify Carbon Absorption at Osiria Ecological Forest
Busan City Corporation is moving forward with the registration of an 'external carbon absorption project' aimed at reducing greenhouse gases at the Osiria Ecological Forest located in Gijang County.The external project registration is a system that officially certifies the carbon absorption capacity of existing forests and ecological parks by a government-designated expert organization. The corporation aims to secure greenhouse gas reduction achievements and enhance its capacity for managing eco-friendly urban spaces.According to a Busan City Corporation official, the organization has been selected as a recipient of free consulting for the external carbon absorption project led by the Korea Forest Service and is currently in the initial preparation stages, including drafting a project plan and collecting basic data.Initially, during the extension of the application period by the Forest Service, Busan City Corporation participated in the project and began to refine it with the support of free consulting. Other regional city corporations, including Daejeon City Corporation, also participated in this application.An official from the corporation stated, "We are currently at the starting line, receiving consulting and have not yet completed formal registration or final certification. We aim to complete the necessary data supplementation and review application by next year, with a target of final registration in the first half of 2028."The total area of the Osiria Ecological Forest, which is the subject of registration, is 14 hectares (approximately 140,000 square meters) and was completed in 2021. This project will not create new forests but will formalize the carbon absorption value of the existing site through an 'in-boundary approach,' similar to the external project registration method pursued by Haeundae Arboretum last March.Regarding the estimation of carbon absorption, the corporation conservatively estimates an annual reduction effect of about 70 tons of greenhouse gases.The official explained, "Based on standard calculation formulas and rough estimates of the number of trees planted, we expect an annual reduction of about 70 tons. The exact reduction amount will be determined through precise calculations and monitoring procedures in the future."Concerning the transfer of management rights for the Osiria green space in Gijang County, the corporation plans to establish a consultation mechanism to ensure that project implementation and performance maintenance are not disrupted.The corporation confirmed through inquiries with relevant departments that even if ownership or management rights change to local governments (Busan City and Gijang County), future business continuity and carbon absorption performance distribution can be maintained through a memorandum of understanding.Additionally, regarding costs incurred after project registration, including monitoring and verification, the corporation will conduct a pilot project for free consulting to assess the necessary budget and gradually incorporate it into the budget for execution.Lee Sang-yong, head of the Strategic Business Division at Busan City Corporation, stated, "The selection for this project will enhance the public value of the green assets created by the corporation and serve as an important opportunity to contribute to the government's carbon neutrality policy. We will establish the experiences gained during the registration and certification process as a standard model and expand its application to future restoration projects and park and green space development initiatives."* This article has been translated by AI.

Climate Response Committee Explores Policy and Financial Support for Low-Carbon Steel Transition
The National Climate Crisis Response Committee has sought policy and financial support to facilitate the low-carbon transition of the steel industry. The committee discussed ways to back investments necessary for technological development and equipment upgrades in the steel sector, aiming to reduce greenhouse gas emissions while maintaining industrial competitiveness.On October 28, the committee held the 'Second Forum on Low-Carbon Transition Policies for the Industrial Sector' at the Peace and Park Convention Center in Seoul, attended by over 100 participants from the government, steel industry, academia, and financial sectors.The steel industry accounted for approximately 39% of greenhouse gas emissions from domestic industrial sectors as of 2018, making it the largest emitter. The forum addressed the direction of the steel industry's low-carbon transition and investment and financial linkage strategies for Korea's green transition initiative, known as 'K-GX.'The Ministry of Trade, Industry and Energy presented the policy direction for the steel industry's low-carbon transition, while the Financial Services Commission outlined the current status and direction of transition financing. The Ministry of Climate, Energy and Environment explained support measures for green and transition investments. Academia and the Korea Chamber of Commerce and Industry also proposed strategies for securing competitiveness in the domestic steel industry and outlined investment plans and challenges for green transition.Steel industry representatives described the challenges of technological development and equipment upgrades, requesting support. POSCO Holdings highlighted the investment burdens associated with the demonstration and commercialization of low-carbon technologies, such as hydrogen reduction steelmaking, and urged the government to lead the creation of a low-carbon steel market, expand clean power and hydrogen supply bases, and establish long-term investment and financing conditions.The Korea Iron and Steel Association proposed tax incentives for low-carbon transition investments, relief from electricity cost burdens, securing high-quality scrap steel, and recognition of the reduction performance of low-carbon steel products as common industry tasks.This forum is part of the activities of the 'Carbon Neutral Grand Alliance,' launched in December 2024, aimed at fostering cooperation among high-emission industries, financial sectors, and relevant government departments. The Climate Response Committee plans to incorporate feedback gathered during the forum into discussions by the 'Green Transition Committee for High-Emission Industries' and share it with relevant departments to review policy linkages and complementary measures.Lee Chang-hoon, the private sector chair of the Climate Response Committee, stated, "The low-carbon transition of industries is a task that requires collaboration between the public and private sectors to reduce greenhouse gas emissions and secure industrial competitiveness. Government policy support, along with climate finance, must effectively connect with corporate investment needs to lead to tangible reductions."* This article has been translated by AI.
