As a bullet teach speeds by means of within the background, a liquid hydrogen tank towers over sun panels and hydrogen gas cells at Panasonic’s Kusatsu plant in Japan. Mixed with a Tesla Megapack garage battery, the hydrogen and sun can ship sufficient electrical energy to energy the web site’s Ene-Farm gas cellular manufacturing facility.

As bullet trains whiz by means of at 285 kilometers according to hour, Panasonic’s Norihiko Kawamura appears to be like over Japan’s tallest hydrogen garage tank. The 14-meter construction looms over the Tokaido Shinkansen Line tracks outdoor the traditional capital of Kyoto, in addition to a big array of sun panels, hydrogen gas cells and Tesla Megapack garage batteries. The facility resources can generate sufficient juice to run a part of the producing web site the use of renewable power simplest.
“This can be the most important hydrogen intake web site in Japan,” says Kawamura, a supervisor on the equipment maker’s Good Power Device Trade Department. “We estimate the use of 120 lots of hydrogen a 12 months. As Japan produces and imports an increasing number of hydrogen sooner or later, this will probably be an excessively appropriate roughly plant.”
Sandwiched between a high-speed railway and freeway, Panasonic’s manufacturing facility in Kusastsu, Shiga Prefecture, is a sprawling 52 hectare web site. It was once initially inbuilt 1969 to fabricate items together with fridges, probably the most “3 treasures” of family home equipment, at the side of TVs and washing machines, that Jap coveted as the rustic rebuilt after the devastation of Global Warfare II.
As of late, one nook of the plant is the H2 Kibou Box, an illustration sustainable energy facility that began operations in April. It is composed of a 78,000-liter hydrogen gas tank, a 495 kilowatt hydrogen gas cellular array made up of 99 5kW gas cells, 570kW from 1,820 photovoltaic sun panels organized in an inverted “V” form to catch essentially the most daylight, and 1.1 megawatts of lithium-ion battery garage.
On one facet of the H2 Kibou Box, a big show signifies the volume of energy being produced in actual time from gas cells and sun panels: 259kW. About 80% of the facility generated comes from gas cells, with sun accounting for the remainder. Panasonic says the ability produces sufficient energy to fulfill the desires of the web site’s gas cellular manufacturing facility — it has top energy of about 680kW and annual utilization of a few 2.7 gigawatts. Panasonic thinks it may be a template for the following era of recent, sustainable production.
“That is the primary production web site of its type the use of 100% renewable power,” says Hiroshi Kinoshita of Panasonic’s Good Power Device Trade Department. “We wish to amplify this resolution against the advent of a decarbonized society.”
The 495kilowatt hydrogen gas cellular array is made up of 99 5KW gas cells. Panasonic says it is the global’s first web site of its type to make use of hydrogen gas cells towards growing a producing plant operating on 100% renewable power.

A synthetic intelligence-equipped Power Control Device (EMS) mechanically controls on-site energy era, switching between sun and hydrogen, to attenuate the volume of electrical energy bought from the native grid operator. As an example, if it is a sunny summer season day and the gas cellular manufacturing facility wishes 600kW, the EMS may prioritize the sun panels, selecting a mix of 300kW sun, 200 kW hydrogen gas cells, and 100kW garage batteries. On a cloudy day, then again, it could decrease the sun part, and spice up the hydrogen and garage batteries, which can be recharged at night time by means of the gas cells.
“A very powerful factor to make production greener is an built-in power device together with renewable power equivalent to sun and wind, hydrogen, batteries and so forth,” says Takamichi Ochi, a senior supervisor for local weather exchange and effort at Deloitte Tohmatsu Consulting. “To do this, the Panasonic instance is with reference to an excellent power device.”
With gray hydrogen, no longer completely inexperienced but
The H2 Kibou Box isn’t completely inexperienced. It relies on so-called gray hydrogen, which is generated from herbal fuel in a procedure that may free up a large number of carbon dioxide. Tankers haul 20,000 liters of hydrogen, chilled in liquid shape to minus 250 Celsius, from Osaka to Kusatsu, a distance of a few 80 km, about as soon as per week. Japan has depended on international locations like Australia, which has higher provides of renewable power, for hydrogen manufacturing. However native provider Iwatani Company, which partnered with Chevron previous this 12 months to construct 30 hydrogen fueling websites in California by means of 2026, has opened a generation heart close to Osaka this is interested in generating inexperienced hydrogen, which is created with out the usage of fossil fuels.
Some other factor this is slowing adoption is charge. Despite the fact that electrical energy is fairly pricey in Japan, it recently prices a lot more to energy a plant with hydrogen than the use of energy from the grid, however the corporate expects Jap govt and trade efforts to beef up provide and distribution will make the component considerably inexpensive.
“Our hope is that hydrogen charge will pass down, so we will be able to reach one thing like 20 yen according to cubic meter of hydrogen, after which we will reach charge parity with {the electrical} grid,” Kawamura mentioned.
Panasonic could also be expecting that Japan’s push to transform carbon-neutral by means of 2050 will spice up call for for brand new power merchandise. Its gas cellular manufacturing facility at Kusatsu has churned out over 200,000 Ene-Farm herbal fuel gas cellular for house use. Commercialized in 2009, the cells extract hydrogen from herbal fuel, generate energy by means of reacting it with oxygen, warmth and retailer sizzling water, and ship as much as 500 watts of emergency energy for 8 days in a crisis. Closing 12 months, it all started promoting a natural hydrogen model focused at business customers. It desires to promote the gas cells within the U.S. and Europe as a result of governments there have extra competitive hydrogen cost-cutting measures than Japan. In 2021, the U.S. Division of Power introduced a so-called Hydrogen Shot program that goals to slash the price of blank hydrogen by means of 80% to $1 according to 1 kilogram over 10 years.
Panasonic does not plan to extend the dimensions of its H2 Kibou Box in the intervening time, short of to look different corporations and factories undertake equivalent power techniques.
It may not essentially make financial sense nowadays, Kawamura says, “however we wish to get started one thing like this so it’s going to be able when the price of hydrogen falls. Our message is: if we wish to have 100% renewable power in 2030, then we should get started with one thing like this now, no longer in 2030.”
