Leading the transition to green energy, building a sustainable future.
Specialized in green hydrogen EPC and integrated wind–solar–storage systems, we deliver full life-cycle solutions globally, with a special focus on South America.
About Us
Founded in 2007, HYVODA is the core entity of Tianjin Huamai Energy Technology Co., Ltd. We are more than equipment suppliers — we are your trusted global energy partner. We specialize in integrating complementary energy sources such as solar energy, natural gas and hydrogen. With solid industrial experience and a global service network, we provide customized, stable, efficient and low-carbon solutions for large-scale projects.
Key Competitive Advantages
Comprehensive Technology Integration
We integrate engineering technologies and optimize electrical, mechanical and power systems to break down interdisciplinary barriers, ensuring stability, efficiency and long-term sustainable operation for every hydrogen production project.
Global Technical Service
We have built a fully integrated global service network covering multiple continents, with professional service centers and partners worldwide to deliver consistent and timely technical support for overseas hydrogen production projects.
Turnkey EPC Service
We possess full-spectrum EPC capabilities covering the entire project life cycle (planning, design, procurement, construction, operation and maintenance —O&M—) up to turnkey handover. We take full responsibility for coordinated, efficient and high-quality execution of hydrogen production plant projects.
Adaptable Solutions
We abandon rigid service models and design solutions tailored to project scale, site conditions, energy demand and regional policies, maximizing project benefits and meeting customized construction requirements.
Engineering Team
Our team comprises senior engineers, project managers and technical specialists with global experience in energy sector EPC contracts and professional qualifications. They are capable of solving complex engineering problems with proven efficiency.
24/7 Support
We manage a dedicated rapid response team operating 24/7 to handle project technical inquiries, technical faults, after-sales requirements and emergencies. This shortens the problem resolution cycle and ensures uninterrupted project progress and stable operation.
Key Solutions
We provide systematic solutions covering all clean energy scenarios.
Complete Green Hydrogen Chain
production, storage, transportation and integrated hydrogen fuel applications.
Wind-Solar-Storage Integration
wind + solar + storage + smart microgrids for energy complementarity and peak management.
Integrated Energy Management
optimization of energy efficiency and remote operation and maintenance based on digital platform.
Seamless Transition・Practical Carbon Reduction
To address the challenges of transitioning from traditional energy to fully green energy, HYVODA offers:
Hydrogen Blending in Natural Gas
gradual increase of hydrogen percentage in existing networks and equipment without modifications, to achieve low-emission operations.
Modernization of Hybrid Power Plants
conversion of diesel/fuel oil power plants to hybrid "natural gas + solar + storage" systems balancing economy and emission targets.
Phased Implementation Roadmap
Phased deployment, fully aligned with your budget and decarbonization schedule, will be carried out with rigorous and adaptive risk control.
Integral Turnkey EPC Services
From the drawing to grid connection, we take full engineering responsibility.
Engineering
Feasibility studies, system design, equipment selection and engineering drawings for optimized solutions.
Procurement
Access to the global supply chain for top‑quality equipment, with strict control over costs and delivery lead times.
Construction
In‑house project teams that guarantee schedule, quality, safety and on‑time delivery.
Operation and maintenance (O&M)
Preventive maintenance, optimization, technical support and after‑sales services for your peace of mind.
Cost leadership
To address the challenges of the transition from traditional energy to fully green energy, HYVODA provides:
Integrated cost control within EPC
As a turnkey EPC supplier, we integrate design, procurement and construction, eliminating surcharges and communication‑related losses caused by subcontracting. Global design optimization reduces rework; centralized purchasing improves bargaining power; coordinated construction shortens schedules, lowering project costs without compromising quality.
Cost advantage of China’s industrial chain
Leveraging the mature large‑scale manufacturing ecosystem for renewables, we source components (panels, batteries, electrolyzers, equipment) at lower costs than competitors. Efficient domestic logistics and export channels ensure shorter delivery cycles and better cost‑value ratio, bringing China‑based advantages to the whole world.
Comprehensive economic optimization of the life cycle
We focus not only on capital expenditure (CAPEX), but also reduce operational expenses (OPEX) by applying effective long‑term O&M strategies. This ensures that the levelized cost of energy (LCOE) and total hydrogen‑production costs are highly competitive over the entire project life‑cycle.
