As a bullet train speeds by in the background, a liquid hydrogen tank towers over solar panels and hydrogen fuel cells at Panasonic’s Kusatsu plant in Japan. Combined with a Tesla Megapack storage battery, the hydrogen and solar can deliver enough electricity to power the site’s Ene-Farm fuel cell factory.

As bullet trains whiz by at 285 kilometers per hour, Panasonic’s Norihiko Kawamura looks over Japan’s tallest hydrogen storage tank. The 14-meter structure looms over the Tokaido Shinkansen Line tracks outside the ancient capital of Kyoto, as well as a large array of solar panels, hydrogen fuel cells and Tesla Megapack storage batteries. The power sources can generate enough juice to run part of the manufacturing site using renewable energy only.

“This may be the biggest hydrogen consumption site in Japan,” says Kawamura, a manager at the appliance 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 highway, Panasonic’s factory in Kusastsu, Shiga Prefecture, is a sprawling 52 hectare site. It was originally built in 1969 to manufacture goods including refrigerators, one of the “three treasures” of household appliances, along with TVs and washing machines, that Japanese coveted as the country rebuilt after the devastation of World War II.

Today, one corner of the plant is the H2 Kibou Field, a demonstration sustainable power facility that started operations in April. It consists of a 78,000-liter hydrogen fuel tank, a 495 kilowatt hydrogen fuel cell array made up of 99 5kW fuel cells, 570kW from 1,820 photovoltaic solar panels arranged in an inverted “V” shape to catch the most sunlight, and 1.1 megawatts of lithium-ion battery storage.

On one side of the H2 Kibou Field, a large display indicates the amount of power being produced in real time from fuel cells and solar panels: 259kW. About 80% of the power generated comes from fuel cells, with solar accounting for the rest. Panasonic says the facility produces enough power to meet the needs of the site’s fuel cell factory — it has peak power of about 680kW and annual usage of some 2.7 gigawatts. Panasonic thinks it can be a template for the next generation of new, 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 fuel cell array is made up of 99 5KW fuel cells. Panasonic says it’s the world’s first site of its kind to use hydrogen fuel cells toward creating a manufacturing plant running on 100% renewable energy.

Tim Hornyak

An artificial intelligence-equipped Energy Management System (EMS) automatically controls on-site power generation, switching between solar and hydrogen, to minimize the amount of electricity purchased from the local grid operator. For example, if it’s a sunny summer day and the fuel cell factory needs 600kW, the EMS might prioritize the solar panels, deciding on a mixture of 300kW solar, 200 kW hydrogen fuel cells, and 100kW storage batteries. On a cloudy day, however, it might minimize the solar component, and boost the hydrogen and storage batteries, which are recharged at night by the fuel 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 manager for climate change and energy at Deloitte Tohmatsu Consulting. “To do that, the Panasonic example is close to an ideal energy system.”

With grey hydrogen, not totally green yet

The H2 Kibou Field is not totally green. It depends on so-called grey hydrogen, which is generated from natural gas in a process that can release a lot of carbon dioxide. Tankers haul 20,000 liters of hydrogen, chilled in liquid form to minus 250 Celsius, from Osaka to Kusatsu, a distance of some 80 km, about once a week. Japan has relied on countries like Australia, which has greater supplies of renewable energy, for hydrogen production. But local supplier Iwatani Corporation, which partnered with Chevron earlier this year to build 30 hydrogen fueling sites in California by 2026, has opened a technology center near Osaka that is focused on producing green hydrogen, which is created without the use of fossil fuels.

Another issue that is slowing adoption is cost. Even though electricity is relatively expensive in Japan, it currently costs much more to power a plant with hydrogen than using power from the grid, but the company expects Japanese government and industry efforts to improve supply and distribution will make the element significantly 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 said. 

Hydrogen market to grow 200-fold in next decade, predicts Goldman Sachs

Panasonic is also anticipating that Japan’s push to become carbon-neutral by 2050 will boost demand for new energy products. Its fuel cell factory at Kusatsu has churned out over 200,000 Ene-Farm natural gas fuel cell for home use. Commercialized in 2009, the cells extract hydrogen from natural gas, generate power by reacting it with oxygen, heat and store hot water, and deliver up to 500 watts of emergency power for eight days in a disaster. Last year, it began selling a pure hydrogen version targeted at commercial users. It wants to sell the fuel cells in the U.S. and Europe because governments there have more aggressive hydrogen cost-cutting measures than Japan. In 2021, the U.S. Department of Energy launched a so-called Hydrogen Shot program that aims to slash the cost of clean hydrogen by 80% to $1 per 1 kilogram over 10 years. 

Panasonic doesn’t plan to increase the scale of its H2 Kibou Field for the time being, wanting to see other companies and factories adopt similar energy systems.

It won’t necessarily make economic sense today, 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.”

E-quipment highlight: Liebherr R 920 G8-E electric crawler excavator

Global mining and construction equipment giant Liebherr recently rolled out its first-ever battery electric crawler excavator, setting a new standard in heavy earth-moving equipment capabilities with low noise levels and zero local emissions.

Liebherr has made headlines in the sustainability space with its massive electric haul trucks and stupefyingly quick 6MW cryo-cooled DC fast chargers, but its conventional mid-sized equipment lines haven’t electrified as quickly, leaning instead on hydrogen combustion and fuel cell efforts. That seems to be changing, however, with the launch of the 20-ton R 920 G8-E – the brand’s first-ever factory fresh HDEV.

The company’s official copy is characteristically low-key, with an emphasis on the facts and features instead of hype:

The new model completes the product range of Liebherr crawler excavators produced in Colmar (France). It is particularly quiet and emission-free. It generates the same output as a diesel machine in the same category and is particularly suitable for building sites that require low noise levels and avoiding exhaust gas emissions, such as in cities or underground operating locations.

LIEBHERR

Despite the lack of excitement in the release copy, there is a lot of excitement about the R 920 G8-E’s innovative new control cab philosophy.

Liebherr INTUSI controls


Dubbed INTUSI (for INTuitive USer Interface), the system integrates intelligent control logic with advanced machine learning capabilities to give operators a highly customizable interface that can follow them from asset to asset, from wheel loader to excavator to haul truck, dramatically flattening the learning curve for operators on a given job site.

Liebherr says INTUSI improves both operational efficiency and user comfort on Liebherr job sites through the integration of a number of new features. From the press release:

  • Haptic feedback – vibrations alert the operator to critical conditions—such as reaching dynamic device limits—enhancing situational awareness and speeding up reaction times.
  • Optical feedback – integrated RGB LEDs on the joystick provide real-time visual cues about device status and servo control, ensuring clear communication without distraction.
  • Functional safety – control elements with status LEDs allow safe operation of critical functions—without requiring two-handed input—streamlining workflow while maintaining safety standards.
  • Hand detection – capacitive proximity sensor detects the operator’s hand automatically, enabling seamless activation of controls only when needed.
  • Display navigation – a mini-joystick embedded in the handle allows for quick and efficient navigation of the display interface, reducing the need to reach for external controls.
  • Ergonomics – multi-stage handle height adjustment ensures optimal comfort and usability, adapting to different operator preferences and working conditions

In addition to the INTUSI-powered custom cockpit, the new Liebherr R 920 G8-E electric excavator ships with your choice of either a 188 or 282 kWh high capacity li-ion battery, which is capable of 150 kW DC fast charging. Fast enough, in other words, to power up the machine during shift changes, if needed.

Electrek’s Take

If the notion of a battery electric Liebherr excavator seems familiar, that’s because it should – the company first converted one of its ultramassive R9400 mining excavators last year, as a proof of concept co-developed with global mining giants Fortescue as they invest in new technology to decarbonize their mines.

Since then, Fortescue has used the machine to move millions of tons of dirt, and has ordered several more. And, because everything from excavators to loaders to heavy trucks are built to be powertrain agnostic, and manufacturers will often offer the same basic vehicle with Cummins, Detroit Diesel, or Volvo power, so there’s a degree of openness baked into those systems already. Liebherr is just taking that to the next level by installing an electric drive motor in place of an internal combustion engine, and I expect this excavator will be the first of many such machines from the brand.

Looks like Rivian is working on a steer-by-wire system

Looks like Rivian is working on a steer-by-wire system

Rivian has posted a job listing for a steering engineer, specifically mentioning work on a future steer-by-wire system for the company.

Steer-by-wire is an automotive concept that has been around for a long time, but hasn’t yet reached mass adoption. The idea is to replace (or supplement) mechanical linkages between the steering wheel and the wheels with electronic actuators instead.

There are a number of potential benefits to this, like allowing more customizability or adaptability to a steering system, reducing mechanical complexity, or adding speed-sensitive variable steering ratios.

Although there are also disadvantages, like a reduction in steering feel (although, since most cars are moving to electronic power steering, that was already gone anyway).

But few cars have implemented steer-by-wire systems, or at least not fully committed to them, given that mechanical steering racks are a relatively solved problem and the general inertia of the car industry which would rather stick with a solution they know than switch to something better (haven’t we here, at this EV publication, heard *that* one before…). There’s also the matter of regulations, which have often been written to require mechanical steering systems, and may need updating to allow for steer by wire.

But, steer by wire made it into mass production with the release of the Tesla Cybertruck. This was big news when Tesla committed to this – at the time, it was the only thing on the road to exclusively use a steer by wire system, though there are other cars with partial steer by wire (for example, mechanical front wheel steering, and steer by wire rear-wheel steering).

But it seems to have opened the floodgates, as a number of other companies are working on or have since released steer by wire systems (Lexus, for example).

And now, it looks like Rivian is one of those companies – though we don’t know if it’s for the front or rear.

The company posted a job listing for “Sr. Staff Technical Program Manager, Steering Actuator System,” based at its Irvine, CA headquarters (spotted by Rivianforums). This wouldn’t be so exceptional, except that the job posting also specifically points out that “you’ll have full cradle-to-grave ownership of the SBW subsystem.”

So – we know they’re working on steer by wire, to some extent.

But a few other EVs, particularly large EVs like the Rivian R1 platform is, use steer by wire just for the rear wheels – for example the Hummer EV and Rolls-Royce Spectre. These systems are particularly helpful for giant vehicles, because it allows them to be more nimble and make turns that otherwise would require a lot more… negotiation in a giant land yacht.

So it’s possible that Rivian is only working on rear wheel steer by wire here, but we’d like to think there’s a chance it’s working on steer by wire for the full vehicle.

We also don’t know if this would show up on all of Rivian’s vehicles, or only on certain models – the R2 and R3 are in development, and the R1 just got a big refresh. But, perhaps even more interestingly (and very speculatively), VW has invested heavily in Rivian for technology help, so we wonder if we might end up seeing this in VW group vehicles, or Scout vehicles eventually…
