Metallica’s European Tour Showcases Renewable-Energy Big Rigs—And Their Limits
The heavy-metal band is using natural gas and vegetable oil to power its 7,200-mile journey, but filling trucks up on sustainable fuels still has a long way to go

Metallica, the band that blazed a trail for thrash metal with rugged guitar riffs and relentless drumbeats, is trying to do something similar for trucks powered by sustainable fuels.
The group, a rock music mainstay since their 1986 hit album “Master of Puppets,” is looking to burnish its bona fides on social issues by using rigs powered by fuels including biomethane and vegetable oil on its European tour this summer.
Working with European truck maker Iveco, the authors of songs including “Battery” and “Fuel” (sample lyric: “Fuel is pumping engines / Burning hard, loose and clean / And I burn, churning my direction / Quench my thirst with gasoline.”) aim to show that sustainable transportation in heavy-duty trucking is possible on European highways dotted with alternative-fuelling stations.
But the trucks’ limitations and the workarounds the band’s logistics providers are undertaking on the meticulously-planned 7,200-mile journey winding through the continent from Sweden to Spain also illustrate how far trucking is from using cleaner fuels in regular operations.
“You have limited options because of the lack of the infrastructure,” said Natasha Highcroft, a director of Suffolk, U.K.-based Transam Trucking, which provides logistics for Metallica and other bands. “We use alternative fuels as and when we can, as much as possible, but until the infrastructure is there it’s very difficult.”
The trucks run on natural gas, vegetable oil, electricity and hydrogen fuel cells, and will be hauling giant video screens, lighting and instruments across nine countries.
The workhorses of Metallica’s tour will be 10 heavy-duty trucks powered by renewable natural gas—such as methane from landfills—and four heavy-duty trucks running on biodiesel or hydrogenated vegetable oil. The trucks, dramatically decked out in Metallica’s fierce logo, can travel about 1,000 miles between refuelling.
Both fuels provide a significant reduction in emissions compared with regular diesel, although emissions experts say they aren’t nearly as clean as battery-electric or hydrogen fuel cell technologies.
The tour was due to kick off this week in Munich, Germany, and over the next two months will cover the continent from Italy and Spain in southern Europe to Denmark and Norway. The longest journey between shows, from Warsaw to Madrid, covers almost 1,800 miles.
Iveco, which is providing the eco-friendly trucks for Metallica’s tour, makes both battery-electric and hydrogen fuel cell big-rig engines, the types that governments in Europe and the U.S. are trying to press on truckers as soon as possible. But because of the lack of charging and fuelling stations on the long legs between gigs, the battery-electric and hydrogen trucks will be mostly for promotional use at concerts, said Gerrit Marx , chief executive of the Italian truck maker.
Marx said Iveco wants to highlight that renewable natural gas and hydrogenated vegetable oil are “more available and ready” than batteries and hydrogen while also being “way better than fossil diesel.”
Europe has hundreds of liquefied natural gas and hydrogenated vegetable oil, or HVO, refuelling stations. A representative for British energy major Shell , which is working with Iveco on the tour, said Metallica’s low-carbon journey wouldn’t have been possible even a couple of years ago.
Shell says its customers can access HVO in five European countries and renewable natural gas in Germany and in the Netherlands. That means that when low-carbon options aren’t available, the Iveco trucks will be fuelled with regular LNG and the HVO trucks will be fuelled with regular diesel.
A Shell representative said the Metallica tour will buy carbon credits to offset “unavoidable emissions“ generated by the low-emission trucks.
U.S. companies are also using renewable natural gas and biodiesel to reduce carbon emissions. But trucking specialists say the fuels aren’t available in sufficient quantities to power the world’s fleets, which is why regulators are pushing battery-electric and hydrogen fuel cell vehicles.
Trucking executives say the costs of operating those technologies are double or triple those of diesel and that they aren’t workable in a highly-competitive, low-margin industry like trucking.
Lars Stenqvist , chief technology officer at truck maker Volvo Group , said it is important that high-profile performers like Metallica amplify the capabilities of sustainable fuels.
Truckers will only adopt the technology when customers demand it, he said, so “This is music to my ears.”

The lunar flyby would be the deepest humans have traveled in space in decades.

It’s go time for the highest-stakes mission at NASA in more than 50 years.
On April 1, the agency is set to launch four astronauts around the moon, the deepest human spaceflight since the final Apollo lunar landing in 1972.
The launch window for Artemis II , as the mission is called, opens at 6:24 p.m. ET.
National Aeronautics and Space Administration teams have been preparing the vehicles to depart from Florida’s Kennedy Space Center on the planned roughly 10-day trip. Crew members have trained for years for this moment.
Reid Wiseman, the NASA astronaut serving as mission commander, said he doesn’t fear taking the voyage. A widower, he does worry at times about what he is putting his daughters through.
“I could have a very comfortable life for them,” Wiseman said in an interview last September.
“But I’m also a human, and I see the spirit in their eyes that is burning in my soul too. And so we’ve just got to never stop going.”
Wiseman’s crewmates on Artemis II are NASA’s Victor Glover and Christina Koch, as well as Canadian Space Agency astronaut Jeremy Hansen.
What are the goals for Artemis II?
The biggest one: Safely fly the crew on vehicles that have never carried astronauts before.
The towering Space Launch System rocket has the job of lofting a vehicle called Orion into space and on its way to the moon.
Orion is designed to carry the crew around the moon and back. Myriad systems on the ship—life support, communications, navigation—will be tested with the astronauts on board.
SLS and Orion don’t have much flight experience. The vehicles last flew in 2022, when the agency completed its uncrewed Artemis I mission .
How is the mission expected to unfold?
Artemis II will begin when SLS takes off from a launchpad in Florida with Orion stacked on top of it.
The so-called upper stage of SLS will later separate from the main part of the rocket with Orion attached, and use its engine to set up the latter vehicle for a push to the moon.
After Orion separates from the upper stage, it will conduct what is called a translunar injection—the engine firing that commits Orion to soaring out to the moon. It will fly to the moon over the course of a few days and travel around its far side.
Orion will face a tough return home after speeding through space. As it hits Earth’s atmosphere, Orion will be flying at 25,000 miles an hour and face temperatures of 5,000 degrees as it slows down. The capsule is designed to land under parachutes in the Pacific Ocean, not far from San Diego.
Is it possible Artemis II will be delayed?
Yes.
For safety reasons, the agency won’t launch if certain tough weather conditions roll through the Cape Canaveral, Fla., area. Delays caused by technical problems are possible, too. NASA has other dates identified for the mission if it doesn’t begin April 1.
Who are the astronauts flying on Artemis II?
The crew will be led by Wiseman, a retired Navy pilot who completed military deployments before joining NASA’s astronaut corps. He traveled to the International Space Station in 2014.
Two other astronauts will represent NASA during the mission: Glover, an experienced Navy pilot, and Koch, who began her career as an electrical engineer for the agency and once spent a year at a research station in the South Pole. Both have traveled to the space station before.
Hansen is a military pilot who joined Canada’s astronaut corps in 2009. He will be making his first trip to space.
Koch’s participation in Artemis II will mark the first time a woman has flown beyond orbits near Earth. Glover and Hansen will be the first African-American and non-American astronauts, respectively, to do the same.
What will the astronauts do during the flight?
The astronauts will evaluate how Orion flies, practice emergency procedures and capture images of the far side of the moon for scientific and exploration purposes (they may become the first humans to see parts of the far side of the lunar surface). Health-tracking projects of the astronauts are designed to inform future missions.
Those efforts will play out in Orion’s crew module, which has about two minivans worth of living area.
On board, the astronauts will spend about 30 minutes a day exercising, using a device that allows them to do dead lifts, rowing and more. Sleep will come in eight-hour stretches in hammocks.
There is a custom-made warmer for meals, with beef brisket and veggie quiche on the menu.
Each astronaut is permitted two flavored beverages a day, including coffee. The crew will hold one hourlong shared meal each day.
The Universal Waste Management System—that’s the toilet—uses air flow to pull fluid and solid waste away into containers.
What happens after Artemis II?
Assuming it goes well, NASA will march on to Artemis III, scheduled for next year. During that operation, NASA plans to launch Orion with crew members on board and have the ship practice docking with lunar-lander vehicles that Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin have been developing. The rendezvous operations will occur relatively close to Earth.
NASA hopes that its contractors and the agency itself are ready to attempt one or more lunar landing missions in 2028. Many current and former spaceflight officials are skeptical that timeline is feasible.
