As a bullet prepare speeds by within the background, a liquid hydrogen tank towers over photo voltaic panels and hydrogen gasoline cells at Panasonic’s Kusatsu plant in Japan. Combined with a Tesla Megapack storage battery, the hydrogen and photo voltaic can ship sufficient electrical energy to energy the location’s Ene-Farm gasoline cell manufacturing facility.

As bullet trains whiz by at 285 kilometers per hour, Panasonic’s Norihiko Kawamura appears to be like over Japan’s tallest hydrogen storage tank. The 14-meter construction looms over the Tokaido Shinkansen Line tracks exterior the traditional capital of Kyoto, in addition to a big array of photo voltaic panels, hydrogen gasoline cells and Tesla Megapack storage batteries. The energy sources can generate sufficient juice to run a part of the manufacturing web site utilizing renewable power solely.
“This stands out as the greatest hydrogen consumption web site in Japan,” says Kawamura, a supervisor on the equipment maker’s Smart Energy System Business Division. “We estimate utilizing 120 tons of hydrogen a 12 months. As Japan produces and imports increasingly hydrogen sooner or later, this might be a really appropriate type of 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 initially in-built 1969 to fabricate items together with fridges, one of many “three treasures” of family home equipment, together with TVs and washing machines, that Japanese coveted because the nation rebuilt after the devastation of World War II.
Today, one nook of the plant is the H2 Kibou Field, an indication sustainable energy facility that began operations in April. It consists of a 78,000-liter hydrogen gasoline tank, a 495 kilowatt hydrogen gasoline cell array made up of 99 5kW gasoline cells, 570kW from 1,820 photovoltaic photo voltaic panels organized in an inverted “V” form to catch probably the most daylight, and 1.1 megawatts of lithium-ion battery storage.
On one aspect of the H2 Kibou Field, a big show signifies the quantity of energy being produced in actual time from gasoline cells and photo voltaic panels: 259kW. About 80% of the facility generated comes from gasoline cells, with photo voltaic accounting for the remainder. Panasonic says the power produces sufficient energy to satisfy the wants of the location’s gasoline cell manufacturing facility — it has peak energy of about 680kW and annual utilization of some 2.7 gigawatts. Panasonic thinks it may be a template for the subsequent era of latest, sustainable manufacturing.

“This is the primary manufacturing web site of its sort utilizing 100% renewable power,” says Hiroshi Kinoshita of Panasonic’s Smart Energy System Business Division. “We wish to increase this answer in the direction of the creation of a decarbonized society.”
An synthetic intelligence-equipped Energy Management System (EMS) mechanically controls on-site energy era, switching between photo voltaic and hydrogen, to reduce the quantity of electrical energy bought from the native grid operator. For instance, if it is a sunny summer season day and the gasoline cell manufacturing facility wants 600kW, the EMS may prioritize the photo voltaic panels, deciding on a combination of 300kW photo voltaic, 200 kW hydrogen gasoline cells, and 100kW storage batteries. On a cloudy day, nonetheless, it’d reduce the photo voltaic part, and increase the hydrogen and storage batteries, that are recharged at evening by the gasoline cells.
The 495kilowatt hydrogen gasoline cell array is made up of 99 5KW gasoline cells. Panasonic says it is the world’s first web site of its sort to make use of hydrogen gasoline cells towards creating a producing plant operating on 100% renewable power.

“The most essential factor to make manufacturing greener is an built-in power system together with renewable power comparable to photo voltaic and wind, hydrogen, batteries and so forth,” says Takamichi Ochi, a senior supervisor for local weather change and power at Deloitte Tohmatsu Consulting. “To try this, the Panasonic instance is near a super power system.”
With gray hydrogen, not completely inexperienced but
The H2 Kibou Field is just not completely inexperienced. It depends upon so-called gray hydrogen, which is generated from pure gasoline in a course of that may launch a number of carbon dioxide. Tankers haul 20,000 liters of hydrogen, chilled in liquid kind to minus 250 Celsius, from Osaka to Kusatsu, a distance of some 80 km, about as soon as per week. Japan has relied on nations like Australia, which has larger provides of renewable power, for hydrogen manufacturing. But native provider Iwatani Corporation, which partnered with Chevron earlier this 12 months to construct 30 hydrogen fueling websites in California by 2026, has opened a know-how middle close to Osaka that’s targeted on producing inexperienced hydrogen, which is created with out using fossil fuels.
Another subject that’s slowing adoption is value. Even although electrical energy is comparatively costly in Japan, it at present prices far more to energy a plant with hydrogen than utilizing energy from the grid, however the firm expects Japanese authorities and business efforts to enhance provide and distribution will make the aspect considerably cheaper.
“Our hope is that hydrogen value will go down, so we will obtain one thing like 20 yen per cubic meter of hydrogen, after which we will obtain value parity with {the electrical} grid,” Kawamura stated.
Panasonic can also be anticipating that Japan’s push to change into carbon-neutral by 2050 will increase demand for brand spanking new power merchandise. Its gasoline cell manufacturing facility at Kusatsu has churned out over 200,000 Ene-Farm pure gasoline gasoline cell for residence use. Commercialized in 2009, the cells extract hydrogen from pure gasoline, generate energy by reacting it with oxygen, warmth and retailer sizzling water, and ship as much as 500 watts of emergency energy for eight days in a catastrophe. Last 12 months, it started promoting a pure hydrogen model focused at industrial customers. It needs to promote the gasoline cells within the U.S. and Europe as a result of governments there have extra aggressive hydrogen cost-cutting measures than Japan. In 2021, the U.S. Department of Energy launched a so-called Hydrogen Shot program that goals to slash the price of clear hydrogen by 80% to $1 per 1 kilogram over 10 years.
Panasonic would not plan to extend the size of its H2 Kibou Field in the intervening time, eager to see different corporations and factories undertake comparable power methods.
It will not essentially make financial sense as we speak, Kawamura says, “however we wish to begin one thing like this so it will likely be prepared when the price of hydrogen falls. Our message is: if we wish to have 100% renewable power in 2030, then we should begin with one thing like this now, not in 2030.”
