2-2. CarbonTech: The Technological Breakthrough for Industrial Decarbonization

• Market dominance and growth potential

The carbon tech sector is one of the fastest-growing segments in the green tech market, with particular attention focused on '2-1. Carbon Capture, Utilization, and Storage (CCUS)' technologies and business areas for achieving carbon neutrality. According to Research and Markets, the global CCUS market is projected to grow from $2.2 billion in 2021 at a CAGR of 27.1%, reaching $9.4 billion by 2027. The domestic CCUS market is projected to grow from KRW 17.1 billion in 2021 to KRW 44.3 billion by 2027, with a CAGR of 17.05%. Demand is particularly high in the steel industry, including companies like POSCO and Hyundai Steel, and in the cement industry. 

The Ministry of Science and ICT-led CCUS initiative launched in April 2025, setting an annual CO₂ capture target of 4.8 million tons by 2030. Meanwhile, POSCO and Hyundai Steel are developing technology to reduce carbon emissions from steelmaking processes by 90% through the introduction of hydrogen-based ironmaking processes (HBI: Hot Briquetted Iron).

Meanwhile, the Korea Emissions Trading System (K-ETS) operates as of February 2025, covering 525 facilities and managing approximately 68% of emissions. Notably, the petroleum refining and aviation sectors maintain a 100% free allocation rate, interpreted as policy support to preserve global competitiveness.

2-2. In the 'Low-Carbon Industrial Processes' sector, the electrification of manufacturing has emerged as a key trend, driving the development of technologies to transition high-temperature processes traditionally reliant on fossil fuels to an electric-based foundation. The Ministry of Trade, Industry and Energy announced the opening of a hydrogen power generation bidding market in May 2025, with clean hydrogen power generation volumes set at 3,000 GWh annually, requiring power generation to commence by 2029. With the government opening a clean hydrogen power generation bidding market annually, the five power generation companies, facing urgent need to build hydrogen and ammonia infrastructure, are expected to actively utilize the coal power generation infrastructure being phased out. This can contribute to decarbonization in the industrial sector. Furthermore, the introduction of the Green Taxonomy (K-Taxonomy) is expanding financial support for the transition to eco-friendly processes. 

‘2-3. Eco-friendly Mobility Infrastructure/Services’ is evolving beyond electric vehicle charging infrastructure into integrated mobility services. MaaS (Mobility as a Service) platforms integrating EV charging, battery management, and car sharing are emerging, and solutions dramatically reducing carbon emissions from urban transportation systems are gaining attention. 

• Investment Strategy Opportunities and Outlook

Investment in the carbon tech sector is significantly influenced by changes in the regulatory/policy environment alongside technical feasibility. The revised emissions trading system in 2025 expanded the scope of companies subject to allocation and increased the proportion of auctioned allowances, substantially boosting demand for carbon reduction technologies. From an investment perspective, the following business areas and technology fields are expected to be promising.

1) Industrial Direct Air Capture (DAC) Technology Technology for directly capturing CO₂ from the atmosphere is entering the commercialization phase, with small-scale distributed DAC solutions showing particular promise. However, the key risk is the shortage of CO₂ storage sites. The most significant structural barrier is the absolute lack of domestic geological storage capacity. The CO₂ storage capacity of the Jeju Basin is estimated at approximately 302Mt (million tons), which is only half of South Korea's 2011 CO₂ emissions (approximately 610Mt). To achieve carbon neutrality by 2050, CO₂ must be sequestered via methods such as subsea storage.  To overcome these geological limitations, the Korea National Oil Corporation (KNOC) has formed a government initiative with the participation of SK E&S and Hanyang University. This initiative is currently conducting a project to evaluate CO₂ storage capacity in the East Sea, West Sea, and South Sea surrounding the Korean Peninsula. The "Comprehensive 2D/3D Geophysical Exploration and Computational Reprocessing for Securing Large-Scale Commercial CO₂ Storage Sites around the Korean Peninsula" project, scheduled for completion in December 2026, is expected to lay the foundation for national carbon capture/storage projects.  Therefore, from an investment strategy perspective, given the domestic storage capacity shortage, it is deemed necessary to construct an investment portfolio focused on the Utilization segment within the CCUS (Carbon Capture, Utilization, and Storage) sector rather than just CCS technology. Additionally, exploring investment opportunities by identifying partner companies for establishing a joint East Asian CO₂ storage hub should also be considered.   2) Other areas include carbon fiber composite materials and carbon footprint measurement/management solutions Carbonfiber composite materials represent high-value material development utilizing captured carbon, with strong demand in construction, automotive, and aerospace industries. Carbon footprint measurement/management solutions are projected to see surging demand for precise carbon accounting solutions as companies face mandatory reporting obligations for Scope 3 emissions (indirect emissions across the entire supply chain). However, the announcement of the ESG disclosure roadmap, which the Korean government had promised to release within the first half of the year, has been somewhat delayed. Although the Financial Services Commission has repeatedly announced plans to release the 'disclosure roadmap' starting in 2024, the deadline has been postponed each time. Since the mandatory ESG disclosure date was pushed back to after 2026, no detailed schedule has been presented.

Investments in the carbon tech sector carry significantly higher risks than other sectors due to uncertainties surrounding technological maturity, commercialization timelines, and policy dependence. Consequently, companies possessing business models based on already proven technologies inevitably become the primary investment targets.

From an investment analyst's perspective, this government-led capital inflow will serve as a powerful momentum supporting the structural growth of the green tech market. 

Green tech investment in Korea from 2025 to 2030 is expected to be restructured around three key areas. ① Scaling up renewable energy and ESS integration projects, ② Substantial commercialization of CCUS or the hydrogen economy, ③ Intelligent environmental data platforms.
Particularly noteworthy is the potential for cross-sector convergence solutions to create new investment opportunities, moving beyond traditional single-technology approaches. Conversely, risks specific to each of the five major sectors (cleantech, carbon tech, ecotech, ag·food tech, geotech) also exist.

[CleanTech Sector]is the most balanced investment target in terms of growth potential and profitability.
In particular, AI-based energy management systems and ESS integration technologies are expected to attract significant investment interest. However, grid stability concerns and the sector's capital-intensive nature (cash flow deferral risk) require careful consideration during investment evaluation.

[Carbon Tech Sector]is a sector highly dependent on regulatory environments and policies, presenting challenges such as technological uncertainty (
) and difficulty in predicting commercialization timelines. Particularly, the shortage of domestic CO₂ storage capacity (approximately 150 million tons) suggests considering a strategic portfolio focused on the Utilization segment within the CCUS field rather than CCS. This requires sensitivity analysis regarding technological validation and changes in regulatory frameworks.

[Eco-Tech Sector]is a mature market with cumulative investments reaching 2.3725 trillion won in waste management and eco-friendly materials.
Particularly, as the EU intensifies its circular economy push, the value of companies participating in global supply chains is expected to rise further. Conversely, cost competitiveness during the scale-up process and compatibility with existing infrastructure are critical. This means cost competitiveness and infrastructure compatibility will be key variables in investment decisions.

[Agri-Food Tech Sector]In South Korea, investment is concentrated in the smart agriculture sector (cumulative investment raised: KRW 367 billion) rather than alternative proteins (cumulative investment raised: KRW 28.9 billion).
Regulatory framework compliance with the Ministry of Food and Drug Safety and consumer acceptance are key variables for investment success.
 

[Geotech Sector]Satellite-based environmental monitoring and blockchain-based carbon trading platforms show long-term promise, while the Bank of Korea and Korea Exchange's experiments with DLT and CBDC are expected to accelerate the digitalization of the carbon market in the long term. 

[Strategic Investment Opportunities to Focus on Between 2025 and 2030]

1. Priority should be given to 'cross-sector convergence business models'.
   Companies capable of offering complex value propositions—such as ESS-end-of-life battery recycling (Second Life) integration or smart farm-renewable energy integrated solutions—can establish higher entry barriers compared to single-technology firms and gain an advantage in diversifying revenue models.
2. 'Positioning from a global value chain perspective.'
   Carbon accounting and monitoring solutions capable of responding to the EU's Carbon Border Adjustment Mechanism (CBAM) and global supply chain restructuring, along with low-carbon raw material supply technologies, can secure high premiums through preemptive investment.
3. Proactive identification of government regulations and policy changes is crucial.
   The 「Offshore Wind Power Special Act」 (full implementation March 26, 2026), the 「Green Transition Guarantee System」 (1.5 trillion won), and the 「Hydrogen Power Generation Bidding Market」 (3,000 GWh of electricity, enough for approximately 850,000 households for one year) are expected to be watershed moments that rapidly transform the industrial ecosystem. This may also warrant considering preemptive investment positioning that leverages the time lag between policy changes and their reflection in the market.

As seen in the trend of impact investment firms establishing specialized climate tech funds, green tech is establishing itself as a core pillar of investment strategies that simultaneously pursue financial returns and environmental value.

Successful green tech investment hinges on the ability to identify opportunities at the intersection of technology, market, and policy. In particular, changes in the regulatory environment—such as mandatory ESG disclosures and the expansion of carbon emissions trading systems—create market inefficiencies, offering alpha-generating opportunities for proactive investors.

Investors should approach green tech investments not merely as environmental assets, but as strategic positioning to secure leadership in future industrial architecture. Considering that while Korean green tech companies have established strong positions in the domestic market, their global market share remains relatively low, growth capital investments in companies with global expansion potential are expected to be more promising.

In conclusion, green tech investments should be recognized not merely as environmental investments, but as opportunities for long-term value creation arising from the structural realignment of global supply chains and the transition of industrial paradigms. Investors should proactively capture opportunities emerging at the intersection of technological innovation and policy shifts, focusing on identifying companies capable of building sustainable competitive advantages through cross-industry convergence.
