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 positioning’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 may be the biggest hydrogen consumption site in Japan,” says Kawamura, a supervisor on the equipment maker’s Smart Energy System Business Division. “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 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 inbuilt 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 illustration 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 essentially 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 remaining. Panasonic says the power produces sufficient energy to fulfill the wants of the positioning’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 first manufacturing site of its kind using 100% renewable energy,” says Hiroshi Kinoshita of Panasonic’s Smart Energy System Business Division. “We want to expand this solution towards the creation of a decarbonized society.”
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 variety to make use of hydrogen gasoline cells towards creating a producing plant working on 100% renewable power.

An synthetic intelligence-equipped Energy Management System (EMS) routinely controls on-site energy era, switching between photo voltaic and hydrogen, to attenuate 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 would possibly prioritize the photo voltaic panels, deciding on a mix of 300kW photo voltaic, 200 kW hydrogen gasoline cells, and 100kW storage batteries. On a cloudy day, nevertheless, it’d decrease the photo voltaic part, and increase the hydrogen and storage batteries, that are recharged at night time by the gasoline cells.
“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,” says Takamichi Ochi, a senior supervisor for local weather change and power at Deloitte Tohmatsu Consulting. “To do that, the Panasonic example is close to an ideal energy system.”
With gray hydrogen, not completely inexperienced but
The H2 Kibou Field isn’t completely inexperienced. It will depend on 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 every week. Japan has relied on nations like Australia, which has higher provides of renewable power, for hydrogen manufacturing. But native provider Iwatani Corporation, which partnered with Chevron earlier this yr to construct 30 hydrogen fueling websites in California by 2026, has opened a expertise middle close to Osaka that’s targeted on producing inexperienced hydrogen, which is created with out the usage of fossil fuels.
Another difficulty that’s slowing adoption is price. Even although electrical energy is comparatively costly in Japan, it at the moment prices rather more to energy a plant with hydrogen than utilizing energy from the grid, however the firm expects Japanese authorities and trade efforts to enhance provide and distribution will make the factor considerably cheaper.
“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 mentioned.
Panasonic can be anticipating that Japan’s push to grow to be carbon-neutral by 2050 will increase demand for brand new power merchandise. Its gasoline cell manufacturing facility at Kusatsu has churned out over 200,000 Ene-Farm pure gasoline gasoline cell for dwelling use. Commercialized in 2009, the cells extract hydrogen from pure gasoline, generate energy by reacting it with oxygen, warmth and retailer scorching water, and ship as much as 500 watts of emergency energy for eight days in a catastrophe. Last yr, 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 does not plan to extend the size of its H2 Kibou Field in the meanwhile, desirous to see different firms and factories undertake related power programs.
It will not essentially make financial sense at this time, Kawamura says, “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.”
