Green hydrogen has emerged as a promising alternative to fossil fuels, offering the potential for a cleaner, more sustainable energy future. However, its journey from an innovative concept to a mainstream energy source is fraught with challenges and uncertainties.
In this blog, we will delve into the current hurdles the green hydrogen sector faces, examine the current market status and development strategies, and explore its future potential, including notable green hydrogen stocks.
Current Challenges in the Green Hydrogen Sector
The first step in investing in green hydrogen stocks is analyzing the challenges. The transition to a green hydrogen economy is ambitious and holds great promise, but is not without significant challenges. These obstacles span financial, technological, social, and political dimensions.
-
High Costs of Production, Storage, and Transportation
Hydrogen, despite being the most abundant element in the universe, is often found combined with other elements. This necessitates complex and costly extraction processes. The production method significantly impacts the cost:
- Black Hydrogen: Produced from coal gasification, it’s the least expensive (roughly $0.95-$1.90/kg) but has the highest carbon footprint.
- Gray Hydrogen: Derived from natural gas, it’s slightly more expensive ($1.27-$2.37/kg) and has a significant carbon footprint.
- Blue Hydrogen: Produced from natural gas with carbon capture and storage, it’s more expensive ($4-$5/kg) due to the additional carbon capture technology.
- Green Hydrogen: Produced via electrolysis using renewable energy, it’s the most expensive ($5.5-$9.5/kg) but has the lowest carbon footprint.
The high cost of green hydrogen is primarily due to the expensive electrolyzers and renewable energy costs. While renewable energy costs have decreased, the upfront investment in electrolyzers and infrastructure remains significant.
Hydrogen must be converted for storage or transportation, adding to the costs:
- Compression: Compressing hydrogen gas costs around $1-$1.5/kg.
- Liquefaction: Liquefying hydrogen requires cooling it to extremely low temperatures, costing $2-$3/kg.
- Ammonia Conversion: Converting hydrogen to ammonia is more economical ($0.4-$0.9/kg), but reconverting ammonia to hydrogen is expensive.
Hydrogen storage also presents challenges:
- Compressed Storage: More expensive than storing methane.
- Liquefied Storage: Requires maintaining extremely low temperatures, increasing energy costs.
- Material-Based Storage: Using solid materials for storage can be costly, with prices ranging from $15-$43/kg depending on the material.
-
Uncertainty in Future Demand
The future demand for green hydrogen remains uncertain. While significant investments and plans for hydrogen development exist, many countries lack a clear hydrogen strategy. The focus remains mainly on blue hydrogen due to its lower production costs and reduced emissions than gray hydrogen.
Green hydrogen’s current applications are limited, with most industries relying on cheaper, fossil-fuel-based hydrogen. There is also a lack of price support policies for green hydrogen, which diminishes its market competitiveness.
-
Environmental Impact of Hydrogen Projects
While promising, green hydrogen production faces resource challenges. It requires substantial water, especially in arid regions.
Additionally, the renewable energy infrastructure needed to power electrolyzers requires significant land. Careful planning is crucial to minimize environmental impacts and ensure green hydrogen aligns with global sustainability goals.
-
Absence of Unified Technical and International Standards
The lack of international hydrogen production and use standards poses a significant barrier. Countries are developing their regulations, leading to inconsistencies and unfair competition. The absence of a unified framework limits the global adoption of green hydrogen and hinders the development of a global hydrogen economy.
Efforts are being made to address this issue, such as the ISO Technical Committee 197, which focuses on international standards for hydrogen technology. However, more comprehensive regulations are needed to ensure safety and fairness in the industry.
-
Public Perception and Safety Concerns
Public acceptance is crucial for the expansion of hydrogen infrastructure. Hydrogen’s flammability and tendency to pose safety concerns must be addressed. Additionally, public opposition, known as the “Not in My Backyard” (NIMBY) phenomenon, can hinder the development of hydrogen projects.
Future Potential and Opportunities in the Green Hydrogen Sector
Despite facing several challenges, the green hydrogen market holds significant future potential. For instance, the recent approval of a 25-megawatt green hydrogen project in Spain highlights the growing momentum in this sector. It promises to reduce emissions across industries, transportation, power systems, and buildings. Green hydrogen can also accelerate renewable energy development and provide flexibility to power systems.
-
Decarbonization Potential
Green hydrogen, produced from renewable energy sources, offers a promising solution to reduce greenhouse gas emissions across various sectors.
While the current hydrogen economy largely relies on fossil fuel-based gray and blue hydrogen, advancements in renewable energy technologies and electrolyzer efficiency drive down the cost of green hydrogen, making it increasingly competitive.
Key areas where green hydrogen can contribute to decarbonization:
- Industrial Processes: Industries like refining, chemical production, and steel manufacturing can significantly reduce carbon footprints by transitioning to green hydrogen. The high hydrogen demand in these sectors presents opportunities for large-scale green hydrogen adoption, leading to economies of scale and lower costs.
- Transportation: Green hydrogen can power heavy-duty vehicles such as trucks, buses, trains, ships, and aircraft. Hydrogen fuel cell electric vehicles offer advantages like faster refueling and longer travel distances than battery electric vehicles.
- Buildings: Green hydrogen can be used for heating, cooking, and cooling in buildings, reducing reliance on fossil fuels. Although the current cost of green hydrogen may limit its widespread adoption, blending it with natural gas can provide a gradual transition to a more sustainable energy source.
As renewable energy costs decline and electrolyzer technology improves, green hydrogen will drop below $2.00/kg by 2030. It is poised to play a crucial role in achieving a decarbonized future.

Boosting Renewable Energy
Increased consumption of green hydrogen will drive the installation of renewable energy systems to meet power needs. By 2050, green hydrogen could account for 19 EJ of the total 351 EJ of global final energy consumption, representing about 5% of total energy use. Producing this hydrogen will require substantial renewable energy inputs, necessitating installed capacities of 4,000 to 16,000 GW.
-
Long-Term Storage Solutions
The need for energy storage will rise with increasing renewable energy capacity. Hydrogen production and storage can offer long-term flexibility and stability, accommodating seasonal variations in renewable energy output. Although hydrogen storage efficiency is relatively low (around 45%), it remains a valuable option in systems with high renewable energy penetration, minimizing excess energy waste and supporting larger renewable installations.
Market Status and Development Strategies

Current Market Overview
Most hydrogen today is used in refining and chemical industries, with gray hydrogen being the most common due to its lower cost. Green hydrogen is still in its early stages, making up less than 1% of the global hydrogen supply,” according to Raymond James analyst Pavel Molchanov.
Government investment in hydrogen research and development is increasing, with significant contributions from countries like China and Japan. Companies in the European Union advocate for a transition from “blue hydrogen” to green hydrogen, supported by carbon capture and storage (CCS) technologies.
According to market research, the green hydrogen market is booming. Its value is expected to skyrocket from $1.1 billion in 2023 to $30.6 billion by 2030, fueled by a 61.1% annual growth rate (CAGR). This growth includes various green hydrogen stocks poised for significant gains.
