What is Green Hydrogen?

Green hydrogen is molecular hydrogen (H₂) produced through water electrolysis using electricity sourced exclusively from renewable energy such as wind, solar, or hydroelectric power. Unlike grey hydrogen, which is generated from fossil fuels and emits significant greenhouse gases, green hydrogen production emits zero carbon emissions. This clean production process positions green hydrogen as a vital energy carrier to decarbonize sectors that are hard to electrify directly, such as heavy industry, long-haul transport, and seasonal energy storage.

The term “green hydrogen” distinguishes it from blue and grey hydrogen:

- Grey hydrogen derives from natural gas via steam methane reforming without carbon capture, emitting large CO₂ quantities.

- Blue hydrogen uses the same production method as grey but incorporates carbon capture and storage technologies to reduce emissions.

- Green hydrogen’s advantage lies in its sustainability and potential for integration with renewable energy surpluses, contributing to energy security and carbon neutrality.

Current Development Status of Green Hydrogen Production

Globally, green hydrogen technology is advancing on multiple fronts—technologically, commercially, and policy-wise. Electrolyzer technologies, which split water into hydrogen and oxygen, are at the heart of green hydrogen production. The main types of electrolyzers include Proton Exchange Membrane (PEM), Alkaline, and Solid Oxide Electrolyzers (SOE). Each has different operational characteristics and maturity levels:

- Alkaline Electrolyzers are the most mature and cost-effective technology, widely deployed for industrial uses but less flexible for variable renewable energy inputs.

- PEM Electrolyzers offer flexibility and high purity hydrogen production, well suited to variable renewables like solar and wind.

- SOE technology is promising for high efficiency but remains mostly in the demonstration phase, due to high operating temperatures and material challenges.

Cost remains a substantial barrier. However, recent trends show a steady decrease in renewable electricity costs and electrolyzer prices, making green hydrogen increasingly competitive. According to the International Energy Agency (IEA), the cost of producing hydrogen from renewables could fall by up to 30% by 2030 due to these improvements and scaling effects. 

Countries like South Korea, Germany, Australia, Japan, and the European Union have established hydrogen roadmaps featuring significant green hydrogen capacity buildout targets as part of their net-zero strategies. South Korea has invested heavily in developing hydrogen production facilities and infrastructure and aims to become a global hydrogen leader through innovation and export initiatives.

Direction and Future Prospects

Looking ahead, green hydrogen is poised to become a fundamental pillar in integrated clean energy systems. Several key directions define the future landscape:

1. Scale-Up and Cost Reduction: Massive deployment of renewable energy capacities and electrolyzers will drive economies of scale, further reducing costs. Innovations in materials and manufacturing processes for electrolyzers will enhance durability and efficiency.

2. Sector Coupling and System Integration: Green hydrogen will integrate with power grids, heating networks, industrial processes, and transportation. For example, blending hydrogen with natural gas in pipelines, using it as feedstock in ammonia or steel production, and powering fuel-cell vehicles are expanding applications.

3. Infrastructure Development: Hydrogen storage, transport and distribution infrastructure will be scaled to facilitate local consumption and international trade. This includes pipeline repurposing, hydrogen liquefaction, and shipping technologies.

4. Policy and Market Mechanisms: Supportive policies such as subsidies, carbon pricing, and renewable hydrogen certification schemes will be vital to create market confidence and attract investment.

5. Research and Innovation: Ongoing R&D focuses on new electrolyzer technologies, such as high-temperature SOE, novel catalysts, and hybrid renewable-hydrogen systems, which promise higher efficiencies and lower environmental impact.

Challenges to Overcome

Despite its promise, green hydrogen production faces notable challenges. Intermittency of renewables can limit continuous hydrogen production; thus, pairing with energy storage or grid management solutions is necessary. The current limited scale means hydrogen supply chains are not yet robust or economical. Additionally, regulatory frameworks and safety standards need harmonization globally to facilitate cross-border hydrogen trade.

However, the combination of policy momentum, technological progress, and increasing climate action urgency has created a dynamic environment for rapid green hydrogen growth.

Conclusion

Green hydrogen production, enabled by renewable electricity-powered electrolysis, offers a transformative pathway to decarbonize energy-intensive sectors and support a sustainable energy future. Advances in electrolyzer technologies, falling production costs, proactive government roadmaps, and integration into broader clean energy systems mark the accelerating progress of this field. Going forward, scaling up production, building dedicated infrastructure, and fostering robust market frameworks will be essential to unlock green hydrogen’s full potential as a versatile, zero-emission energy carrier.

As nations pursue ambitious climate goals, green hydrogen stands at the forefront of clean energy innovation. Its evolution will reshape global energy markets, support energy security, and drive a sustainable green economy. For Korea and the world, investing in green hydrogen means investing in a resilient, low-carbon future.

Thanks.

Accelerating Renewable Energy Development and Deployment in ASEAN

The ASEAN region faces both opportunities and challenges in scaling up renewable energy capacities. Notably, the Philippines secured over 10 GW of renewable energy capacity by 2029 through its 4th Green Energy Auction (GEA-4) conducted in 2025. The auction capped solar power bids at 72 USD/MWh, significantly below the market’s average wholesale price of 94 USD/MWh. This demonstrates that competitive bidding can provide long-term renewable electricity supplies at costs lower than existing market rates. Transitioning to competitive auctions is therefore an efficient pathway for ASEAN countries to expand renewable energy while reducing costs simultaneously.

However, state-owned utilities in several ASEAN countries suffer from weak financial health, raising the perceived investment risks and financing costs associated with renewables. The prevailing “single-buyer” market structure means state utilities—often deeply indebted—are considered high-risk buyers, increasing equity and debt costs for renewable projects. Power Purchase Agreements (PPAs) also face challenges such as delayed payments or regulatory changes, undermining project financing certainty. While corporate renewable PPAs are emerging worldwide as a key mechanism to boost renewables, they remain at a nascent stage in ASEAN due to regulatory and approval complexities.

Countries like Malaysia, Singapore, Thailand, and Vietnam are experimenting with PPA expansions, but their share relative to total power demand remains modest. Malaysia operates a Corporate Green Power Program enabling renewable electricity procurement via renewable energy certificates (RECs), while Singapore allows buyers to contract with licensed power retailers to access renewable power through the grid. Thailand pilots up to 2 GW of corporate PPAs facilitating direct renewable purchases by large consumers, and Vietnam’s 2024 PPA framework accommodates both physical and virtual contracts.

Simplifying permitting processes is crucial to avoid costly project delays. Growing local community engagement and benefit-sharing frameworks can also reduce social opposition to large-scale renewable projects, limiting uncertainty. ASEAN countries are making commitments to phase down fossil fuel-based generation, including coal power plants. For instance, Indonesia plans to reduce coal-fired plants by the mid-2030s through conversions like biomass co-firing and carbon capture technology. The Philippines is halting new coal plant construction and exploring emissions trading incentives for early retirements. Vietnam aims to close or repurpose all coal plants by 2050. However, such transitions require aligning power system flexibility and stable operations with long-term contracts for fossil capacity, demanding comprehensive reforms.

Currently, most ASEAN members (except Vietnam) are still at early integration stages of variable renewables, with limited grid impacts evidenced so far. This allows relatively low-cost management of renewables’ output variability. But many countries operate with inflexible long-term contracts and surplus coal generation capacity, which limits the ability to reduce fossil output during low-demand or high renewable output periods. The inadequate ancillary services compensation mechanisms and inclusion of such services in PPAs restrict renewables’ flexibility response.

In summary, ASEAN’s renewable energy growth depends on clear and detailed long-term energy plans to reduce investor uncertainty and finance costs, robust reforms to improve PPA frameworks and market structures, streamlined permitting, expanded corporate renewable procurement, fossil generation phase-out aligned with grid flexibility enhancement, and active community engagement. These measures are critical to transition ASEAN’s energy sector towards affordability, efficiency, and decarbonization.

Understanding the Australian Energy Market Operator: Managing the Future of Power

In Australia, the smooth operation and reliability of energy supply across states rely heavily on a central institution known as the Australian Energy Market Operator (AEMO). Established to oversee the efficient management of electricity and natural gas markets, AEMO plays a crucial role in balancing supply and demand, ensuring safe energy delivery, and facilitating the transition towards cleaner and more sustainable energy sources.

What is AEMO?

AEMO is the independent organization responsible for operating Australia’s wholesale electricity market and gas markets, as well as managing the country’s power system 24/7. By acting as the “market operator,” AEMO balances generation and consumption in real time through a process called “dispatch,” which determines which power plants run and when, to maintain system stability and meet demand efficiently.

The electricity market managed by AEMO covers the National Electricity Market (NEM) — spanning Queensland, New South Wales, Victoria, South Australia, and Tasmania — while the gas market includes major eastern and western states. AEMO also prepares forecasts, oversees planning and development, and manages emergency operations when needed.

Challenges in Managing Australia’s Energy Future

Australia’s energy landscape is rapidly evolving, with increasing adoption of decentralized renewable energy systems such as rooftop solar panels and battery storage distributed among households and businesses. This trend creates new challenges for AEMO’s traditional centralised approach, as energy flows become less predictable and more complex to control.

Moreover, energy consumption in large metropolitan areas is highly concentrated, prompting discussions about decentralizing energy management and improving infrastructure in regional and rural areas. This is critical to ensure equitable energy access and support sustainable growth beyond major cities.

Looking Ahead: Policy and Technology Innovations

AEMO is actively involved in reforms aimed at enhancing market flexibility and supporting Australia’s climate goals. This includes advancing smart grid technologies, integrating electric vehicles as dynamic loads, and promoting demand response programs where consumers adjust usage based on grid conditions.

In addition, market design reforms planned for 2025 and 2026 aim to better accommodate the variability of renewable energy and foster investment in new energy infrastructure. These reforms also emphasize increased transparency and consumer participation.

What Does This Mean for Energy Consumers?

For end users, developments led by AEMO promise greater energy reliability and competitive pricing, alongside new opportunities to participate in energy markets through technologies like smart meters and peer-to-peer trading platforms. Consumers in regional areas can also expect improvements in infrastructure that better reflect local needs.

Conclusion

The Australian Energy Market Operator stands at the heart of Australia’s energy transition, balancing the complex demands of today’s power system while steering towards a sustainable future. With innovative policy changes and technological advancements on the horizon, AEMO’s role will be more vital than ever in ensuring a reliable, efficient, and green energy market across Australia.

China-EU Electric Vehicle Trade: From Tariffs to Price Commitment Agreements

The trade relationship between China and the European Union (EU) in the electric vehicle (EV) sector is undergoing a notable transformation. Chinese electric cars have surged in popularity across Europe, challenging established automakers and attracting increasing consumer attention. However, this rise has not come without tensions. The EU's investigation into China's state subsidies for EV manufacturers led to the imposition of countervailing tariffs, aiming to protect European industry from unfair competition. Recently, both sides agreed on a pioneering price commitment framework to replace tariffs, signaling a new chapter in electric vehicle trade and cooperation.

Understanding the Subsidy Dispute and Tariff Measures

Public subsidies granted by the Chinese government to domestic EV producers have long been a subject of concern for the EU. These subsidies help lower the production cost and retail prices of Chinese electric vehicles, allowing them an advantage in foreign markets. In October 2023, the European Commission launched a formal anti-subsidy investigation targeting Chinese EV imports. After thorough analysis, the EU found that subsidies led to unfair competition and imposed countervailing duties of up to 35.3% in late 2024, intended to neutralize the subsidy impact.

Countervailing duties differ from standard tariffs in that they specifically target subsidy-induced price distortions. They are imposed to restore a fair level playing field, compensating for the price advantage that subsidies create. These tariffs apply for a five-year term, affecting mainly Chinese EV models entering the EU market directly.

Despite these tariffs, the volume of Chinese EVs sold in Europe continued to grow remarkably. Between 2024 and 2025, sales jumped from around 408,000 units to approximately 700,000 units across the EU, the United Kingdom, and the European Free Trade Association (EFTA) countries. This growth reflects robust consumer demand, competitive pricing, and the increasing acceptance of Chinese EV brands in Europe.

The Shift to Price Commitment Mechanisms

Recognizing the limitations of tariffs as a long-term solution, Chinese and EU negotiators sought a more sustainable, transparent approach to address subsidies and trade fairness. By mid-2025, they agreed to explore a price commitment arrangement in which Chinese automakers voluntarily agree to a minimum export price for their electric vehicles sold in Europe. This mechanism effectively replaces tariffs with a price floor, ensuring that exported vehicles are sold at prices that offset subsidy advantages.

The benefit of such an approach is multifaceted. For the EU, it protects its automotive industry by setting a clear pricing boundary, preventing artificially low import prices. For Chinese manufacturers, it allows tariff-free access to the market if they comply with the pricing commitments, simplifying trade flows and reducing administrative burdens related to tariff compliance.

European Commission’s Price Commitment Guidelines

On January 12, 2026, the European Commission issued detailed guidelines to implement this mechanism. Key features include:

- Chinese EV manufacturers must submit a binding application detailing their price commitments, consistent with eliminating the effects of subsidies.

- The minimum export prices must be credible in practice, ensuring market enforcement is feasible.

- The system should prevent the risks of cross-subsidization, where profits from non-subsidized products might otherwise offset lower-priced subsidized vehicles.

- Ongoing monitoring and transparency are essential to maintain the integrity of the agreement.

If companies meet these criteria, they gain approval and are allowed to export and sell their EVs in Europe without tariffs under this price commitment scheme.

Strategic Responses by Chinese EV Makers: Local Production in Europe

Alongside trade negotiations, many leading Chinese electric vehicle firms have taken proactive steps by establishing or expanding manufacturing capabilities within Europe. Doing so circumvents tariff barriers completely and offers strategic advantages such as shorter supply chains, better customization for local consumers, and compliance with increasingly strict EU regulations.

For example, BYD, a dominant player in the Chinese EV industry, has already started production in Hungary and Turkey. They are also exploring opportunities in Spain, aiming to complement their existing manufacturing base. The recent launch of a BYD and Chery joint venture production line in Spain culminated with the rollout of their first vehicle in November 2024.

Similarly, another heavyweight, the Guangzhou Automobile Group (GAC), collaborates with Magna International at a plant in Austria to produce the AION V SUV, a model under the GAC Ion sub-brand. This joint production initiative helps establish local supply networks and strengthens GAC's market presence in Europe.

Such local manufacturing investments align with the EU’s industrial policy priorities and reflect commitments to long-term engagement in the European EV sector.

Market Implications and Consumer Impact

The price commitment agreement and local production strategies reflect an evolving marketplace. They signal a shift from confrontational trade barriers toward cooperative, rule-based mechanisms that encourage fair competition while fostering market growth.

European consumers stand to benefit from a broader choice of cleaner, more affordable electric vehicles. Chinese manufacturers continue to offer competitive pricing, innovation, and diverse model offerings, challenging traditional European automakers to innovate and improve.

From a policy perspective, the EU’s ability to enforce price commitments rather than relying solely on tariffs reflects a more nuanced trade approach. It balances enforcement with facilitation, helping to create a more predictable business environment for all parties involved.

Outlook: Toward Sustainable International EV Trade

The China-EU price commitment deal could serve as a model for future trade resolutions involving new technology sectors where subsidies play a significant role. By prioritizing transparency and market-based price controls, this approach provides a practical alternative to prolonged tariff disputes.

Moreover, this framework encourages Chinese firms to align their pricing with international norms while securing access to critical foreign markets. It also stimulates local production partnerships, boosting employment and industrial collaboration within Europe.

This cooperation aligns with broader global pushes toward sustainability, clean transportation, and reducing carbon emissions. Electric vehicles remain a cornerstone of these efforts, making the smooth functioning of international EV trade systems vital.

Conclusion

The ongoing evolution in China-EU electric vehicle trade relations highlights the complexity of balancing industrial policy, fair competition, and market openness in a rapidly transforming sector. The recently agreed price commitment framework replaces traditional countervailing duties with a more sophisticated pricing mechanism. This method promises to protect European manufacturers from unfair subsidies while ensuring the uninterrupted availability of competitively priced Chinese EVs to European consumers.

Additionally, the trend of Chinese electric vehicle companies establishing local production facilities in Europe complements these trade measures by further embedding them in the regional automotive ecosystem. Together, these developments illustrate how global trade policies are adapting to the realities of modern, clean technology industries with an emphasis on cooperation and sustainability.

For stakeholders in the automotive sector, policymakers, and environmentally conscious consumers, this agreement represents a meaningful step toward fairer and more efficient electric vehicle market dynamics in Europe and beyond.

China's Solar PV Waste Market: Current Challenges and Future Prospects

As China’s initial solar photovoltaic (PV) installations reach the end of their life cycles, the disposal and recycling of solar waste modules have emerged as pressing issues on a national scale. According to recent estimates, the volume of discarded solar modules in China is set to increase drastically in the coming decades. With projections indicating that by 2030 the cumulative recycling market for solar waste could reach approximately 26 billion yuan, and by 2050 exceeding 420 billion yuan, the scale of this challenge—and opportunity—is enormous. This evolving dynamic has propelled the Chinese government to elevate the solar waste recycling industry into formal policy discussions, marking an important step toward systematic management and resource recovery.

Despite these clear policy signals, the on-ground reality reveals several significant hurdles impeding the market's growth. The current supply of solar waste modules remains limited, mainly confined to defective products from manufacturing, decommissioned rooftop panels, losses from power plant installations, and damage caused by natural disasters. Large volumes expected from centralized solar power plants have yet to enter the recycling market, held back by difficulties in residual value assessment, high transportation costs, and issues related to disposing of state-owned assets. Consequently, many private companies entering the recycling business face low plant utilization rates due to insufficient input materials.

Investment challenges compound the situation—setting up a recycling production line capable of processing tens of megawatts annually demands initial investments ranging from 7 to 8 million yuan, while larger-scale facilities require hundreds of millions of yuan for plant, equipment, and labor, making rapid industry expansion difficult. Moreover, the lack of standardization across the recycling sector creates further inefficiencies. Each company tends to deploy custom equipment and processes, which drives up operational costs and acts as a barrier to scaling up.

Nevertheless, efforts by both state-owned and private enterprises show promise. China’s State Power Investment Corporation has established a production line capable of processing 30 MW per year, with plans to enhance automation and informatization to boost recovery rates beyond 92.5%. Similarly, affiliates of China Orient Asset Management are undertaking large-scale projects backed by investments exceeding 18 billion yuan, underscoring the confidence in and potential of this emerging market.

Policy innovation is also underway. The introduction of a "white list" system for recycling companies, which sets clear criteria on energy consumption, pollutant emission, and recycling rates, seeks to incentivize environmentally and economically sustainable practices. Additionally, institutional solutions like the Circular Economy Group’s linkage of residual value assessment with asset trading aims to mitigate controversies around state-owned asset depreciation, thus creating a more transparent and incentivized environment for large-scale PV waste recycling.

In summary, while China’s solar PV waste recycling market faces significant obstacles—including supply constraints, high costs, and fragmentation—the combination of governmental policy support, substantial investment, and technological advances is laying the foundation for future growth. If the market achieves higher volume inflows and benefits from streamlined standards and mechanisms, the industry’s viability and profitability can improve substantially. This transformation will also contribute to addressing critical environmental concerns by enabling the circular use of valuable materials from end-of-life solar modules, reinforcing China’s leadership in sustainable energy development.

Overall, the challenges are complex and multifaceted, but the strides in policy and investment demonstrate a clear trajectory toward establishing a robust recovery and recycling ecosystem for solar PV waste in China. The scale and impact of this new market will likely become a significant factor in the country’s energy and environmental landscape in the coming decades.

Thanks.

Building a Sustainable Hydrogen Value Chain: Insights into China’s First Phase Hydrogen Pilot Areas

China’s commitment to advancing hydrogen energy technologies is manifesting through its strategic pilot projects that aim to build a comprehensive hydrogen value chain across multiple regions. The National Energy Administration (NEA) has designated nine pilot areas along with 41 targeted projects for the first phase of hydrogen energy demonstration, focusing on integrating regional resources, industrial clusters, and infrastructure for efficient hydrogen production, storage, transport, and utilization.

Among these pilot regions, Jilin Province's Changchun-Songyuan-Baicheng corridor is emerging as a core hub in Northeast China by leveraging a stable supply of renewable energy to enable large-scale green hydrogen production. Ningxia’s Ningdong area is developing China’s “Green Hydrogen Valley,” where renewable energy-driven hydrogen production facilitates decarbonization in energy-intensive industries. In the Hebei Province, the “Beijing-Hebei-Tianjin Hydrogen Corridor” initiative reflects a forward-looking approach to link hydrogen production with high-pressure transport pipelines and advanced storage systems. These projects aim to reduce hydrogen transport costs drastically—from about 13 yuan per kilogram to under 3 yuan per kilogram—by 2026, boosting economic viability significantly.

Storage innovations also play a key role, with projects in Hubei Province pioneering deep underground rock cavern hydrogen storage—the first of its kind in China—which is expected to reduce annual carbon emissions by 120,000 tons once completed. This method highlights how China is investing in diverse storage technologies, including liquid and solid-state forms, to ensure safe and scalable hydrogen reserves.

Hydrogen usage is expanding across industrial and energy sectors as well. Green hydrogen is increasingly replacing fossil fuels in heavy industries such as refining and coal chemical sectors, helping to establish low-carbon production models. The energy sector harnesses hydrogen for distributed power supply and grid adjustment, supporting overall energy system flexibility. Especially notable are the projects in the Xinjiang Uyghur Autonomous Region focusing on combining green hydrogen with heavy industry decarbonization, while the Inner Mongolia Autonomous Region is exploring ammonia fuel gas turbines to stabilize power supply within industrial and mountainous zones.

A critical element of this pilot phase is creating differentiated development strategies tailored to each region’s unique resource endowment and industrial characteristics. For example, the northern “triangle” region (Jilin, Inner Mongolia, and Ningxia) acts primarily as a hydrogen supply base; eastern coastal provinces function as consumption centers, and central regions are designed to serve as storage and transport hubs. This approach fosters collaboration rather than isolated efforts, aiming to avoid duplicates and reduce unnecessary resource consumption through national platforms and standards supporting cooperation.

Technological advances are also at the forefront, with projects involving cutting-edge, off-grid hydrogen production units capable of being operational within five minutes. This flexibility is vital to integrate fluctuating renewable power efficiently. Additionally, large-scale hydrogen pipeline construction across Inner Mongolia, Hebei, and Guangzhou enhances long-distance transport capacity, complemented by high-density, diversified mixed hydrogen storage systems.

Together, these efforts highlight China’s strategic push to scale its hydrogen energy infrastructure effectively while addressing key challenges around coordination, cost reduction, and technological maturity. The pilot projects not only lay the foundation for a hydrogen economy but also serve as a model for regional specialization and synergy, likely leading to substantial carbon emission reductions and enhanced renewable energy integration by the mid-2020s.

Given the accelerating global shift toward clean energy, China’s example demonstrates the importance of a unified, phased approach combining technology innovation, regional specialization, and industrial collaboration. As hydrogen emerges as a cornerstone for sustainable energy systems, these initiatives highlight scalable pathways for other countries aiming to build their hydrogen ecosystems. Monitoring the progression of these pilot projects in the coming years will offer valuable insights for policymakers, industry players, and researchers worldwide.

Thanks.
