As a bullet educate speeds by in the history, a liquid hydrogen tank towers more than photo voltaic panels and hydrogen fuel cells at Panasonic’s Kusatsu plant in Japan. Mixed with a Tesla Megapack storage battery, the hydrogen and solar can produce sufficient electrical energy to power the site’s Ene-Farm gasoline mobile manufacturing unit.

As bullet trains whiz by at 285 kilometers for every hour, Panasonic’s Norihiko Kawamura seems to be above Japan’s tallest hydrogen storage tank. The 14-meter structure looms over the Tokaido Shinkansen Line tracks exterior the ancient funds of Kyoto, as perfectly as a big array of solar panels, hydrogen gas cells and Tesla Megapack storage batteries. The ability resources can crank out ample juice to run aspect of the manufacturing web site working with renewable strength only.
“This may be the greatest hydrogen consumption web-site in Japan,” states Kawamura, a manager at the equipment maker’s Sensible Electricity System Organization Division. “We estimate working with 120 tons of hydrogen a calendar year. As Japan makes and imports much more and much more hydrogen in the foreseeable future, this will be a incredibly suited sort of plant.”
Sandwiched concerning a higher-pace railway and freeway, Panasonic’s factory in Kusastsu, Shiga Prefecture, is a sprawling 52 hectare website. It was at first developed in 1969 to manufacture products which include refrigerators, one particular of the “3 treasures” of household appliances, along with TVs and washing equipment, that Japanese coveted as the region rebuilt after the devastation of Globe War II.
Right now, 1 corner of the plant is the H2 Kibou Discipline, a demonstration sustainable energy facility that begun functions in April. It is made up of a 78,000-liter hydrogen fuel tank, a 495 kilowatt hydrogen fuel cell array designed up of 99 5kW fuel cells, 570kW from 1,820 photovoltaic photo voltaic panels arranged in an inverted “V” form to catch the most sunlight, and 1.1 megawatts of lithium-ion battery storage.
On one particular aspect of the H2 Kibou Subject, a massive display signifies the volume of electric power staying manufactured in authentic time from gas cells and photo voltaic panels: 259kW. About 80% of the electrical power generated comes from gasoline cells, with photo voltaic accounting for the rest. Panasonic says the facility produces plenty of electrical power to fulfill the requirements of the site’s gasoline mobile factory — it has peak power of about 680kW and once-a-year utilization of some 2.7 gigawatts. Panasonic thinks it can be a template for the next generation of new, sustainable producing.
“This is the initial manufacturing site of its form employing 100% renewable electrical power,” claims Hiroshi Kinoshita of Panasonic’s Wise Energy Technique Enterprise Division. “We want to increase this alternative in the direction of the creation of a decarbonized society.”
The 495kilowatt hydrogen fuel cell array is created up of 99 5KW gasoline cells. Panasonic suggests it is the world’s first web site of its form to use hydrogen gasoline cells towards developing a producing plant managing on 100% renewable power.

An synthetic intelligence-equipped Vitality Administration Program (EMS) mechanically controls on-web page energy generation, switching among photo voltaic and hydrogen, to limit the total of electricity procured from the regional grid operator. For instance, if it can be a sunny summer working day and the gas mobile manufacturing unit wants 600kW, the EMS could possibly prioritize the photo voltaic panels, choosing on a mixture of 300kW solar, 200 kW hydrogen fuel cells, and 100kW storage batteries. On a cloudy working day, however, it might lower the solar part, and boost the hydrogen and storage batteries, which are recharged at evening by the fuel cells.
“The most critical issue to make producing greener is an built-in energy technique such as renewable electricity these types of as photo voltaic and wind, hydrogen, batteries and so on,” says Takamichi Ochi, a senior supervisor for local weather improve and energy at Deloitte Tohmatsu Consulting. “To do that, the Panasonic case in point is shut to an great power program.”
With grey hydrogen, not absolutely inexperienced nonetheless
The H2 Kibou Area is not thoroughly green. It is dependent on so-named grey hydrogen, which is created from organic gas in a method that can launch a whole lot of carbon dioxide. Tankers haul 20,000 liters of hydrogen, chilled in liquid variety to minus 250 Celsius, from Osaka to Kusatsu, a distance of some 80 km, about at the time a 7 days. Japan has relied on international locations like Australia, which has better provides of renewable energy, for hydrogen generation. But regional supplier Iwatani Corporation, which partnered with Chevron previously this yr to establish 30 hydrogen fueling websites in California by 2026, has opened a technologies heart near Osaka that is concentrated on developing inexperienced hydrogen, which is designed devoid of the use of fossil fuels.
Another concern that is slowing adoption is value. Even while electrical power is fairly pricey in Japan, it at this time fees substantially additional to power a plant with hydrogen than applying power from the grid, but the corporation expects Japanese federal government and marketplace efforts to enhance offer and distribution will make the component significantly less costly.
“Our hope is that hydrogen price will go down, so we can reach anything like 20 yen for each cubic meter of hydrogen, and then we will be capable to attain value parity with the electrical grid,” Kawamura claimed.
Panasonic is also anticipating that Japan’s thrust to grow to be carbon-neutral by 2050 will strengthen demand from customers for new electrical power items. Its gas cell manufacturing facility at Kusatsu has churned out over 200,000 Ene-Farm purely natural fuel gas mobile for residence use. Commercialized in 2009, the cells extract hydrogen from pure gasoline, produce ability by reacting it with oxygen, warmth and shop sizzling h2o, and deliver up to 500 watts of emergency energy for 8 days in a catastrophe. Past 12 months, it started promoting a pure hydrogen variation qualified at commercial customers. It needs to offer the fuel cells in the U.S. and Europe simply because governments there have far more aggressive hydrogen charge-chopping steps than Japan. In 2021, the U.S. Department of Vitality released a so-termed Hydrogen Shot software that aims to slash the price of clean hydrogen by 80% to $1 for every 1 kilogram about 10 several years.
Panasonic would not strategy to raise the scale of its H2 Kibou Field for the time currently being, seeking to see other firms and factories adopt comparable electrical power devices.
It will not likely essentially make economic perception currently, Kawamura states, “but we want to commence one thing like this so it will be completely ready when the value of hydrogen falls. Our information is: if we want to have 100% renewable energy in 2030, then we have to start with one thing like this now, not in 2030.”
