Green Hydrogen Production, Storage, and Utilization System
We used our expertise in air conditioning system engineering to provide onsite green hydrogen infrastructure powered by renewable energy. We contribute to our customers’ decarbonization and carbon neutrality by producing and storing green hydrogen with no CO2 emissions from production to use and supplying it as a raw material for power generation, fuel, and industry.

Features
- Our water electrolyzers are the solid polymer (PEM) type, and thus have high load-following capacity and are optimal for producing hydrogen from renewable energy, which can be very inconsistent.
- The system uses volatile supplies of renewable energy to produce and store hydrogen, which it then uses to balance the supply of electricity with demand.
- Storing hydrogen involves no energy loss—it can be stored for months and even years, making it an apt energy supply during disasters, power outages, and other emergencies.
- We provide optimal solutions to meet your needs, including for products manufactured by other companies.
Solid polymer water electrolyzer “Hydro Creator®“
A water electrolyzer made by Takasago Thermal Engineering.
Unique approach
- We developed this water electrolyzer using technology cultivated over many years under our integrated water electrolysis-fuel cell system
- We developed this water electrolyzer from the perspective of equipment users
Proprietary cell stack
- We leveraged our knowledge of integrated cell development to develop a high-efficiency cell stack for electrolysis (5–15 points higher than conventional cell stacks)
- Our proprietary design and manufacturing technology enables us to provide custom-made products tailored to customers’ needs
Proprietary system
- Our distinct moisture capturing technology contributes to improved system efficiency (10–20 points higher than conventional systems)
- Our distinct control technology reduces the negative impact of output fluctuations on performance

Case study
Microgrid in the Atsuta District of Ishikari, Hokkaido
- The system uses solar power (163 kW) to supply electricity to five public facilities in the Atsuta District of Ishikari
- The system features storage batteries (50 kW/168 kWh) and a hydrogen system (water electrolyzer and fuel cell) to store energy to maximize the availability of solar power
- Designed with direct current between photovoltaic generation, storage batteries, and power conditioner to reduce power conversion losses
- When disasters strike, the system automatically switches to autonomous mode and can supply electricity to designated evacuation centers for at least 72 hours
