As a bullet practice runs within the background, a liquid hydrogen tank lifts photo voltaic panels and hydrogen gasoline cells at Panasonic’s Kusatsu plant in Japan. Mixed with a Tesla Megapack storage battery, the hydrogen and photo voltaic can present sufficient electrical energy to energy the Ene-Farm gasoline cell manufacturing facility on website.

Whereas the bullets are touring at 285 kilometers per hour, Panasonic’s Norihiko Kawamura appears at Japan’s tallest hydrogen storage tank. The 14-meter construction sits above the tracks of the Tokaido Shinkansen Line exterior the traditional capital of Kyoto, in addition to quite a few photo voltaic panels, hydrogen gasoline cells and Tesla Megapack storage batteries. The ability sources generate sufficient juice for use in a part of the manufacturing website utilizing solely renewable vitality.
“This would be the largest hydrogen consumption space in Japan,” mentioned Kawamura, a supervisor of the equipment maker’s Good Power System Enterprise Division. “We estimate that we use 120 tons of hydrogen a yr. As Japan produces and imports an increasing number of hydrogen sooner or later, it is a very appropriate sort of plant.”
Nestled between a high-speed rail and freeway, Panasonic’s manufacturing facility in Kusastsu, Shiga Prefecture, is a sprawling 52-hectare website. It was initially based in 1969 to fabricate gadgets together with fridges, one of many “three treasures” of dwelling home equipment, together with TVs and washing machines, which the Japanese desired as a nation to rebuild. additionally after the destruction of the Second World Conflict.
At present, one nook of the plant is the H2 Kibou Subject, an indication sustainable energy facility that started operations in April. It consists of a 78,000-liter hydrogen gasoline tank, a 495 kilowatt hydrogen gasoline cell array consisting of 99 5kW gasoline cells, 570kW from 1,820 photovoltaic photo voltaic panels organized in an inverted “V” formed to seize essentially the most daylight, and 1.1 megawatts of lithium-ion battery storage.
On one facet of the H2 Kibou Subject, a big show exhibits the quantity of energy produced in actual time from the gasoline cell and photo voltaic panel: 259kW. About 80% of the ability generated comes from gasoline cells, with photo voltaic accounting for the remainder. Panasonic says the ability produces sufficient energy to fulfill the wants of the positioning’s gasoline cell manufacturing facility – it has a peak energy of about 680kW and an annual use of about 2.7 gigawatts. Panasonic thinks it may very well be a template for the following technology of progressive, sustainable manufacturing.
“That is the primary manufacturing space of its type utilizing 100% renewable vitality,” mentioned Hiroshi Kinoshita of Panasonic’s Good Power System Enterprise Division. “We need to develop this resolution in direction of making a decarbonized society.”
The 495kilowatt hydrogen gasoline cell array consists of 99 5KW gasoline cells. Panasonic says it’s the first website on the earth of its type to make use of hydrogen gasoline cells to create a producing plant that runs on 100% renewable vitality.

A man-made intelligence-equipped Power Administration System (EMS) routinely controls on-site energy technology, 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, EMS may prioritize photo voltaic panels, deciding on a mixture of 300kW photo voltaic, 200kW hydrogen gasoline cells, and 100kW of storage batteries. On a cloudy day, nonetheless, it might scale back the photo voltaic element, and increase the hydrogen and storage batteries, that are recharged at evening by gasoline cells.
“A very powerful factor to make manufacturing greener is an built-in vitality system together with renewable vitality resembling photo voltaic and wind, hydrogen, batteries and others,” mentioned Takamichi Ochi, a senior supervisor for innovation. -or local weather and vitality at Deloitte Tohmatsu Consulting. “To do this, the Panasonic instance is near a really perfect vitality system.”
With grey hydrogen, it’s not but absolutely inexperienced
H2 Kibou Subject shouldn’t be fully inexperienced. It relies on so-called grey hydrogen, which is generated from pure gasoline in a course of that releases a whole lot of carbon dioxide. Tankers transport 20,000 liters of hydrogen, cooled in liquid kind to minus 250 Celsius, from Osaka to Kusatsu, which is about 80 km away, about as soon as per week. Japan depends on international locations resembling Australia, which have larger provides of renewable vitality, for hydrogen manufacturing. However the native provider Iwatani Company, which cooperated Chevron earlier this yr to construct 30 hydrogen fueling websites in California by 2026, opening a expertise heart close to Osaka targeted on producing inexperienced hydrogen, created with out using fossil fuels.
One other problem slowing adoption is value. Though electrical energy is comparatively costly in Japan, a hydrogen plant at the moment prices greater than utilizing energy from the grid, however the firm expects Japanese authorities and trade efforts to enhance provide and demand. distribution will make the aspect extra inexpensive.
“Our hope is that the price of hydrogen will lower, in order that we are able to obtain one thing like 20 yen per cubic meter of hydrogen, after which we are going to obtain parity with the price of {the electrical} grid,” he mentioned. Kawamura
Panasonic additionally expects that Japan’s push to develop into carbon-neutral by 2050 will improve demand for brand spanking new vitality merchandise. Its gasoline cell manufacturing facility in Kusatsu has produced greater than 200,000 Ene-Farm pure gasoline gasoline cells 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 inside eight days of a calamity. Final yr, it started promoting a pure hydrogen model geared toward business customers. It desires to promote gasoline cells within the US and Europe as a result of governments there have extra aggressive hydrogen cost-cutting measures than Japan. In 2021, the USA Division of Power launched a so-called Hydrogen Shot program that goals to chop the price of clear hydrogen by 80% to $1 per 1 kilogram inside 10 years.
Panasonic has no plans to extend the size of the H2 Kibou Subject in the mean time, eager to see different firms and factories undertake comparable vitality programs.
It would not essentially make financial sense now, says Kawamura, “however we need to begin one thing like this in order that it may be prepared when the price of hydrogen falls. Our message is: if we need to have 100% renewable vitality by 2030, then we have to begin one thing like this now, not in 2030.”
