In-Depth Analysis & Strategic Recommendations: Participation in the Joint Crediting Mechanism (JCM) and Hydrogen-Related Support Programs
Excerpt from the presentation of Ms. Tomoe Kobayashi from Nippon Koei Corporation at the Hydrogen Linkage Workshop - Bringing hydrogen into the industrialization process in Vietnam and ASEAN
1. Context & Significance
The Joint Crediting Mechanism (JCM), funded by the Government of Japan, aims to accelerate the dissemination of CO₂ reduction technologies such as green hydrogen, renewable energy, and storage solutions.
- 
Direct financial support: covers 20–50% of initial investment costs. 
- 
Improved project bankability: lower CAPEX shortens payback period and improves project attractiveness to financiers. 
- 
Carbon credits: can be shared between Japan and Vietnam, adding potential revenue from future carbon markets. 
With a total budget of approx. JPY 11 billion (around VND 2 trillion) for FY2025–2027, JCM is a major “catalyst” enabling businesses to adopt low-carbon technologies at reduced costs.
2. Requirements & Challenges
a. Project Selection Criteria
- 
Cost-effectiveness threshold: ≤ JPY 4,000/tCO₂eq (~VND 704,000/tCO₂eq). 
- 
Decreasing subsidy rate: as the number of similar projects in Vietnam increases (≥8), the subsidy rate drops from 50% to 20% or may no longer apply. 
- 
MRV (Measurement, Reporting, Verification): projects must demonstrate verifiable CO₂ reductions under Japanese standards. 
b. Business Challenges
- 
Application capacity: requires technical and language capability (English/Japanese) to prepare documentation and MRV reports. 
- 
Co-financing requirement: JCM covers only part of the cost; remaining funds must be mobilized. 
- 
Market risks: power price volatility, carbon credit price fluctuations, and OPEX uncertainty. 
3. Strategic Opportunities for Businesses
- 
Take advantage of early-stage high subsidy (2025–2026): 
 Since the number of hydrogen projects in Vietnam is still low (0–3 selected so far), businesses may receive the maximum 40–50% support.
- 
Combine complementary technologies: 
 Use JCM to fund entire integrated systems:- 
Solar + BESS to power electrolysis 
- 
Energy Management Systems (EMS) to maximize CO₂ reduction 
 
- 
- 
Japan–Vietnam–ASEAN collaboration: - 
Work with Japanese contractors to meet technical and MRV standards more easily 
- 
Leverage Vietnam projects as pilots and replicate across ASEAN 
 
- 
4. Specific Recommendations
For Vietnamese Companies
- 
Early planning: Prepare proposals for FY2025–2026 to secure higher subsidy rates. 
- 
Build internal MRV capability: Train staff to conduct emission reduction reporting, reducing reliance on external consultants. 
- 
Smart financing: Combine JCM with concessional loans (ODA, climate funds, domestic green credit lines). 
For ASEAN Companies
- 
Regional value chain integration: Connect cross-border hydrogen demand (e.g., Singapore–Vietnam shipping corridors). 
- 
Use Vietnam as a sandbox: Pilot projects in Vietnam before replicating in Thailand, Indonesia, etc. 
- 
Engage Japanese partners early: Japanese entities are mandatory representatives in many JCM projects — early engagement increases selection probability. 
5. Action Plan Summary
- 
Step 1: Assess potential CO₂ reduction and calculate cost per tCO₂eq. 
- 
Step 2: Contact consulting firms such as Nippon Koei or VAHC for project design support. 
- 
Step 3: Form a consortium with Japanese partners and prepare submission before the next call. 
- 
Step 4: Develop MRV, O&M, and reporting plans for the entire project lifecycle.
