Feature: Hydrogen Society
KeidanrenSDGs.com has collected many innovative cases contributing to achieve Society 5.0 for SDGs. In this article, we'd like to introduce some of them, Toyota, Taiyo Nippon Sanso, NSSMC, Chiyoda Coporation and Mitsubishi Hitachi Power Systems, related to Hydrogen smart&sustainable society.
Development of Fuel Cell Vehicles, “Ideal Eco-Cars”
TOYOTA MOTOR CORPORATION
MIRAI (Fuel Cell Vehicle)
Through the chemical reaction between hydrogen and oxygen, fuel cell vehicles(FCV) generate electricity to power a motor. They are ideal eco-cars which discharge only water. Toyota has made use of its hybrid vehicle technology as core technology in the development of fuel cell vehicles. In addition to excellent environmental credentials, fuel cell vehicles are fun to drive, and also offer convenience and performance.
Furthermore MIRAI can be used a a generator during disasters. Hydrogen can be produced from a wide range of primary energy sources, and also can be stored as hydrogen for power supply. Additionally it is able to be combined with renewable energy sources.
Toyota sees great potential in fuel cell vehicles which can make it sustainable society for mobility with energy diversification.
Developing a low-cost multifunctional hydrogen refueling station for a hydrogen energy-based society
TAIYO NIPPON SANSO CORPORATION
Fuel cell vehicles (FCVs) run on hydrogen and emit no carbon dioxide. For the spread of FCVs, it is critical to establish hydrogen refueling stations to supply hydro gas to the vehicles. Taiyo Nippon Sanso has developed the Hydro Shuttle packaged hydrogen refueling station based on its long-accumulated industrial gas manufacturing and supply technology. The station is provided as a package of cost- and weight-saving downsized devices and costs only about half the price of a conventional hydrogen refueling station. Moreover, the station is movable and can serve in multiple ways, for example, as an on-site station equipped with hydrogen manufacturing equipment, an off-site station that simply supplies hydrogen, and as a station that travels to supply hydrogen gas to specific users.
HRX19®, the ultimate stainless-steel solution for high-pressure hydrogen stations that will revolutionize the hydrogen society
Nippon Steel & Sumitomo Metal Corporation (NSSMC)
The development of hydrogen stations and other elements of infrastructure will be essential to the market penetration of fuel-cell vehicles (FCVs). HRX19® is a new stainless-steel we have developed for piping, coupling, and valve applications within the high-pressure hydrogen environments of commercial hydrogen stations. It has the following features: (1) Hydrogen gas embrittlement resistance For the improved service life and safety of hydrogen station piping (2) High-strength material HRX19 boasts approx. twice the strength of conventional materials for use in high-pressure hydrogen environments. This makes it possible for stations to be designed with thinner walls and for pipes to be made with larger internal diameters, resulting in larger capacity and shorter hydrogen filling times. In addition, weight reductions contribute to lower CO2 emissions and trucking costs. (3) Weldability Supports applications that utilize welding-based fabrication methods instead of couplings, thus facilitating reduced installation and maintenance costs
To achieve CO2-free power generation, or 100% hydrogen power
Mitsubishi Hitachi Power Systems, Ltd.
Hydrogen conversion project at natural gas GTCC power plant
Hydrogen-fueled gas turbine is expected to make a major contribution to easing the burden on the global environment during power generation. MHPS participates in hydrogen conversion project at natural gas GTCC power plant in the Netherlands, and support feasibility study about the field of gas turbine. The project aims to convert one of the three existing units to 100% hydrogen by 2023. As a result, CO2 emission of one GTCC can be reduced from 1.3 million tons per year to zero.
Hydrogen supply chain development
Building a SPERA hydrogen® supply chain
Chiyoda Corp. was the world's first company to develop SPERA hydrogen® -- a stable liquid formulation of hydrogen -- utilizing a dehydrogenation catalyst that incorporates platinum nano-particles. Although it is a clean energy, hydrogen is also considered difficult to handle. The SPERA hydrogen® system, however, allows hydrogen to be safely and easily handled and transported in large volumes. Moreover, this breakthrough in hydrogen transport has set the stage for the supply of hydrogen as a new and renewable energy resource. Burning hydrogen produces zero CO2 emissions. Additionally, SPERA hydrogen can be stored for long periods or transported over long distances at ambient pressures and temperatures. SPERA hydrogen will aid the battle against global warming on several fronts, whether utilized as a fuel by power stations or through the development of supply infrastructure for hydrogen-powered vehicles. The supply of hydrogen as an energy resource will be a huge first step toward sustainability and the creation of a low-carbon society.
