As a bullet train speeds by in the background, a liquid hydrogen tank towers over photovoltaic panels and hydrogen fuel cells at Panasonic’s Kusatsu plant inJapan Combined with a Tesla Megapack storage battery, the hydrogen and solar can provide adequate electrical energy to power the website’s Ene-Farm fuel cell factory.

As bullet trains whiz by at 285 kilometers per hour, Panasonic’s Norihiko Kawamura examines Japan’s highest hydrogen tank. The 14- meter structure towers above the Tokaido Shinkansen Line tracks outside the ancient capital of Kyoto, along with a big variety of photovoltaic panels, hydrogen fuel cells and Tesla Megapack storage batteries. The source of power can create adequate juice to run part of the making website utilizing renewable resource just.
“This may be the biggest hydrogen consumption site in Japan,” states Kawamura, a supervisor at the home appliance maker’s Smart Energy System BusinessDivision “We estimate using 120 tons of hydrogen a year. As Japan produces and imports more and more hydrogen in the future, this will be a very suitable kind of plant.”
Sandwiched in between a high-speed train and highway, Panasonic’s factory in Kusatsu, Shiga Prefecture, is a vast 52 hectare website. It was initially integrated in 1969 to make products consisting of fridges, among the “three treasures” of home home appliances, in addition to Televisions and cleaning makers, that Japanese yearned for as the nation rebuilt after the destruction of World War II.
Today, one corner of the plant is the H2 Kibou Field, a presentation sustainable power center that began operations inApril It includes a 78,000- liter hydrogen fuel tank, a 495 kilowatt hydrogen fuel cell variety comprised of 99 5kW fuel cells, 570 kW from 1,820 photovoltaic photovoltaic panels organized in an inverted “V” shape to capture the most sunshine, and 1.1 megawatts of lithium-ion battery storage.
On one side of the H2 Kibou Field, a big screen shows the quantity of power being produced in genuine time from fuel cells and photovoltaic panels: 259 kW. About 80% of the power created is approximated to come from fuel cells each year, with solar accounting for the rest. Panasonic states the center produces adequate power to fulfill the requirements of the website’s fuel cell factory– it has peak power of about 680 kW and yearly use of some 2.7 gigawatts. Panasonic believes it can be a design template for the next generation of brand-new, sustainable production.
“This is the first manufacturing site of its kind that aims at using 100% renewable energy,” states Hiroshi Kinoshita of Panasonic’s Smart Energy System BusinessDivision “We want to expand this solution towards the creation of a decarbonized society.”
An synthetic intelligence-equipped Energy Management System (EMS) immediately manages on-site power generation, changing in between solar and hydrogen, to decrease the quantity of electrical energy bought from the regional grid operator. For example, if it’s a warm summer season day and the fuel cell factory requirements 600 kW, the EMS may focus on the photovoltaic panels, choosing a mix of 300 kW solar, 200 kW hydrogen fuel cells, and 100 kW storage batteries. On a cloudy day, nevertheless, it may decrease the solar part, and enhance the hydrogen and storage batteries, which are charged in the evening by the fuel cells.
The 495 kilowatt hydrogen fuel cell variety is comprised of 99 5KW fuel cells. Panasonic states it’s the world’s very first website of its kind to utilize hydrogen fuel cells with the objective of developing a factory working on 100% renewable resource.

“The most important thing to make manufacturing greener is an integrated energy system including renewable energy such as solar and wind, hydrogen, batteries and so on,” states Takamichi Ochi, a senior supervisor for environment modification and energy at Deloitte TohmatsuConsulting “To do that, the Panasonic example is close to an ideal energy system.”
With grey hydrogen, not completely green yet
The H2 Kibou Field is not completely green. It depends upon so-called grey hydrogen, which is created from gas in a procedure that can launch a great deal of co2. Tankers haul 20,000 liters of hydrogen, cooled in liquid type to minus 250 Celsius, from Osaka to Kusatsu, a range of some 80 km, about when a week. Japan has actually depended on nations like Australia, which has higher products of renewable resource, for hydrogen production. But regional provider Iwatani Corporation, which partnered with Chevron previously this year to construct 30 hydrogen sustaining websites in California by 2026, has actually opened an innovation center near Osaka that is concentrated on producing green hydrogen, which is developed without using nonrenewable fuel sources.
Another problem that is slowing adoption is expense. Even though electrical energy is reasonably costly in Japan, it presently costs a lot more to power a plant with hydrogen than utilizing power from the grid, however the business anticipates Japanese federal government and market efforts to enhance supply and circulation will make the component substantially less expensive.
“Our hope is that hydrogen cost will go down, so we can achieve something like 20 yen per cubic meter of hydrogen, and then we will be able to achieve cost parity with the electrical grid,” Kawamura stated.
Panasonic is likewise expecting that Japan’s push to end up being carbon-neutral by 2050 will enhance need for brand-new energy items. Its fuel cell factory at Kusatsu has actually produced over 200,000 Ene-Farm gas fuel cell for house usage. Commercialized in 2009, the cells extract hydrogen from gas, create power by responding it with oxygen, heat and shop warm water, and provide up to 500 watts of emergency situation power for 8 days in a catastrophe. Last year, it started offering a pure hydrogen variation targeted at business users. It wishes to offer the fuel cells in the U.S. and Europe due to the fact that federal governments there have more aggressive hydrogen cost-cutting procedures thanJapan In 2021, the U.S. Department of Energy released a so-called Hydrogen Shot program that intends to slash the expense of tidy hydrogen by 80% to $1 per 1 kg over 10 years.
Panasonic does not prepare to increase the scale of its H2 Kibou Field for the time being, wishing to see other business and factories embrace comparable energy systems.
It will not always make financial sense today, Kawamura states, “but we want to start something like this so it will be ready when the cost of hydrogen falls. Our message is: if we want to have 100% renewable energy in 2030, then we must start with something like this now, not in 2030.”
