image from : suryaenergi.co.id

Green hydrogen has rapidly emerged as a key pillar in the energy transition. Produced by splitting water using renewable electricity (electrolysis), it offers a carbon-free alternative for hard-to-decarbonize sectors such as heavy industry, long-haul transport, and chemical manufacturing. However, scaling up green hydrogen globally requires not only production capacity but also robust infrastructure and massive investment. This article examines current trends in production, infrastructure development, and investment, as well as the challenges and opportunities ahead.

1. Production: Where Are We Now

1.1 Scale and Key Projects

• Current global green hydrogen production is still modest compared to overall hydrogen demand. Most hydrogen today is still “grey” (made from fossil fuels without carbon capture). Global Growth Insights+3expertmarketresearch.com+3IEA+3

• There are however some large flagship projects underway. For example, the NEOM Green Hydrogen Project in Saudi Arabia is expected to have about 3.9 GW of renewable power (solar and wind) feeding into electrolyzers, producing green hydrogen and AMMONIA for global export. Wikipedia

• Another is the Fukushima Hydrogen Energy Research Field (FH2R) in Japan: this facility integrates solar power, electrolysis, and hydrogen production, serving as a model for renewable energy-driven hydrogen. Wikipedia

• The Western Green Energy Hub in Australia is also a key example: enormous wind + solar capacity (tens of GW range) aimed at producing millions of tonnes per year of green hydrogen or green ammonia for both domestic use and export. Wikipedia

1.2 Trends in Production Growth & Cost

• Electrolyzer capacity is projected to grow steeply in the next few years. Some forecasts suggest global capacities might increase from a few gigawatts currently to tens or even hundreds of gigawatts by 2030. Quick Market Pitch+2Global Growth Insights+2

• As capacity scales up, costs are falling. In regions with abundant renewables (solar, wind), green hydrogen is moving closer to competitiveness with hydrogen from fossil fuels. Policy incentives, economies of scale, and improved electrolyzer efficiency are key to this. LinkedIn+2Quick Market Pitch+2

2. Infrastructure: Building the Backbone

Green hydrogen production is only part of the story—unless the infrastructure to transport, store, distribute, and convert hydrogen is in place, uptake will remain constrained.

2.1 Key Infrastructure Elements

• Electrolyzer factories: producing stations/gigs of electrolyzer capacity is crucial. The more capacity for manufacturing electrolysers, the faster and cheaper deployment becomes. Quick Market Pitch+2IEA+2

• Feed‐in renewable energy supply: green hydrogen requires renewable electricity. Solar PV farms, wind farms (onshore and offshore), as well as supportive grid connections, are essential. Regions with cheap and plentiful renewable resources are advantaged. Global Growth Insights+2P Market Research+2

• Water supply and purification: electrolysis requires clean water. In many large projects, desalination or water treatment plants are factored in. Otherwise, water scarcity or cost can be a limiting factor. (E.g. India’s Mulapeta project includes a desalination facility.) The Times of India

• Storage and transport: hydrogen (or hydrogen carriers like ammonia) must be stored and transported. This includes pipelines, shipping, and conversion infrastructure. Some regions are repurposing existing gas pipelines for hydrogen blends or for pure hydrogen transport. P Market Research+1

• Refueling and end-use infrastructure: for transport (fuel cell vehicles, heavy trucks, ships), you need hydrogen refueling stations. For industry, you may need conversion plants (e.g. ammonia cracking, steel processes using hydrogen). Some pilot hydrogen “cities” are building integrated infrastructure from production to distribution. The Ulsan Green Hydrogen Town in South Korea is one example. Wikipedia

2.2 Infrastructure Growth Projections

• The global hydrogen infrastructure market (production, storage, distribution, refueling) was valued around USD 5.4 billion in 2023 and is projected to grow to USD 12.76 billion by 2032. That implies a compound annual growth rate (CAGR) of about 10.05%. GlobeNewswire

• Many countries are planning “hydrogen hubs” or clusters: geographic regions where production, industrial offtakers, transport, and infrastructure are co-located so as to reduce cost and maximize efficiency. Europe, China, India, the U.S., Australia and Middle East actors are major participants. Global Growth Insights+1

3. Investment: Funding the Transition

Scaling up green hydrogen demands vast sums of investment. Below are some of the trends, numbers, and key enablers.

3.1 Investment Volumes & Forecasts

• In recent years, global investment into low-emission hydrogen (green and other clean hydrogen forms) has grown significantly. There are many announced projects across the pipeline. IEA+2LinkedIn+2

• According to White Papers and market reports, by 2030, green hydrogen investment could be in the tens of billions annually. Some forecasts suggest that by 2050, the market (supply chain, infrastructure, production) could require trillions of dollars cumulatively. Deloitte+1

3.2 Geographic Patterns

• Asia-Pacific: major ambitions in China, India, South Korea, etc. China is investing heavily in electrolyzer manufacturing, industrial clusters, and large scale renewables. India has announced policies aiming for large green hydrogen capacity, export focus, and industrial use. Global Growth Insights+2IEA+2

• Middle East & North Africa (MENA): Saudi Arabia’s NEOM project is a flagship; other sun-rich and wind-rich regions see export potential in green hydrogen or derivatives (like ammonia). Global Growth Insights+1

• Europe: strong regulatory push, climate targets, hydrogen bank and other subsidy mechanisms. EU aims to decarbonize hard industries and integrate hydrogen infrastructure into industrial zones. GlobeNewswire+1

• United States: tax credits, hydrogen hubs programs, incentives under the IRA are bolstering investments. LinkedIn+1

3.3 Policy & Financial Instruments

• Production tax credits (PTCs), subsidies, contract-for-difference (CfD) schemes, guaranteed offtake agreements, feed-in tariffs, renewable energy mandates—all are being deployed in various jurisdictions to reduce investment risk. LinkedIn+1

• Blended finance structures are emerging: combining public funds & grants with private capital to de-risk first-of-a-kind projects. Development finance institutions (DFIs) are playing a role, especially in emerging markets. IEA+1

4. Challenges & Barriers

For all the promise, there are significant hurdles to overcome.

• Cost: Although falling, green hydrogen remains expensive relative to fossil-based hydrogen (unless externalities and carbon are priced in). Electrolyzer cost, renewable energy cost, water cost, and system integration contribute.

• Intermittency & grid issues: Renewable power is often variable. Ensuring high capacity utilization for electrolyzers without huge energy wastage or grid instability is challenging.

• Water availability & quality: Electrolysis requires purified water. In many regions, sourcing water affordably (and sustainably) is nontrivial.

• Infrastructure build-out speed: Pipelines, storage, refueling stations, transport infrastructure—these require long lead times, permitting, regulatory alignment.

• Policy/regulatory risk: Investors need certainty. Frequently, projects are delayed or cancelled due to shifting subsidies, unclear regulations, or lack of long-term demand guarantees. The IEA has noted many hydrogen projects in early stages that may not reach final investment decision. Reuters+1
