The future home market will also need hydrogen sensors


Just like large lithium batteries, the application of hydrogen energy will gradually enter the home market from vehicles. The green energy home hydrogen storage system announced by Australian startup Lavo in 2022 can be connected to home solar inverters and water purification devices. Excess solar energy can be used to produce hydrogen through the process of electrolyzing water. Its patented "hydrogen storage alloy" for storing hydrogen can compress hydrogen to less than 1/1000 of its gaseous volume and store it. Has the advantage of low risk of leakage and can be stored under low pressure. , can store about 40 kilowatt hours of energy, which is three times the storage capacity of Tesla's lithium battery energy storage device Powerwall 2, and can provide a household with electricity for 2 days. This device is extremely suitable for households in remote areas to be self-sufficient in electricity.

Japanese builder Sekisui House Co., Ltd. is developing a house that stores electricity in a hydrogen storage tank made of hydrogen-absorbing alloy, and is scheduled to be commercialized in the summer of 2025. Hydrogen-absorbing alloys are currently made of rare metals such as nickel and cobalt. In the future, they are expected to be replaced by general materials such as aluminum-iron or titanium-iron alloys to reduce costs.
Kitakyushu City in Japan has carried out a hydrogen energy town demonstration project and laid a 1.2-kilometer-long hydrogen pipeline to ensure a stable supply of hydrogen from the factory to the hydrogen demonstration room, and to support the technical demonstration and demonstration of various hydrogen-related products. R&D. Leak detection is one of the most important items in infrastructure and safety equipment. In April 2023, Rinnai Industry and Iwatani Co., Ltd. announced that they will install new hydrogen combustion water heaters in Kitakyushu in hydrogen apartment buildings that receive hydrogen pipeline supply, and evaluate them through actual usage conditions. This water heater was announced by Japan's Rinnai Industrial in May 2022 and was successfully developed based on the company's long-term accumulation of combustion technology and fluid control technology in gas appliances. It is the first in the world to use 100% hydrogen fuel. Since water heaters account for a large proportion of household carbon dioxide emitting equipment, they have become a target for hydrogenation. In addition to Japan, Rinnai also cooperates with the Australian Gas Infrastructure Group (AGIG),

A hydrogen water heater has been installed in a hydrogen house in Victoria, and the equipment is being verified and is scheduled to be put into practical use in 2030. In addition to Rinnai, Noritsu has also developed a 100% hydrogen fuel household water heater.
It is scheduled to be launched in Japan after 2025, and plans to develop another exhaust-type hydrogen water heater mainly used in the European and Australian markets, scheduled to be commercialized in 2025 or later.
Gas stoves are another high-carbon-emitting household appliance that require hydrogenation. In October 2022, Rinnai and Toyota Motor Corporation began to jointly develop new applications for burning hydrogen cooking in Shizuoka Prefecture.
The introduction of hydrogen fuel into homes is still in the experimental stage, but it can show the vast reach of the hydrogen energy market and is also the future stage of hydrogen sensors.
