NÜRTINGEN, Germany & SALZBURG, Austria--(BUSINESS WIRE)--Nov 27, 2025--
ADS-TEC Energy (NASDAQ: ADSE), a global leader in battery-based energy storage and fast-charging systems, and Salzburg AG, a regional energy and infrastructure provider in Austria, announced the successful technical prequalification of the ChargePost fast charging system for participation in the Austrian ancillary services market. Salzburg AG has integrated ChargePost into its virtual power plant, where it now contributes to maintaining grid stability.

The prequalification confirms that ChargePost is capable of providing short-term power adjustments to help stabilize grid frequency. This represents a new category of fast charging infrastructure: one that not only serves electric vehicles but adds value in an increasingly flexible and decentralized energy system.
ChargePost combines ultra-fast DC charging of up to 300 kW with up to 201 kWh of battery capacity, even when connected to the standard low-voltage grid. Its bidirectional storage and intelligent energy management enable:
These capabilities illustrate how battery-integrated fast charging can operate efficiently and reliably, even in areas with limited local grid capacity.
At a joint event in Salzburg on November 25, Thomas Speidel, founder and CEO of ADS-TEC Energy, together with Salzburg AG board members Michael Baminger and Herwig Struber, marked ChargePost’s successful prequalification.
Thomas Speidel said, “To accelerate growth, fast charging has to evolve from being a cost center. With intelligent buffering and stable grid behavior, systems like ChargePost open up new flexibility in the operation of charging infrastructure. Our work with Salzburg AG shows how high-power charging and grid stability can go hand in hand.”
Further expansion of the collaboration
ADS-TEC Energy has also won a tender from Salzburg AG for 20 additional ChargePost systems. This commitment demonstrates the importance of the two companies' strategic partnership as they continue to build-out battery-supported fast charging infrastructure in the region.
A technology milestone that delivers new market opportunities
ChargePost’s prequalification demonstrates that it meets the criteria required to provide ancillary services – a capability traditionally reserved for standalone, large-scale battery storage systems. This compact multi-use architecture enables fast charging and grid support in a single system, offering utilities and charging operators a scalable approach that can be replicated across additional regions and markets.

COPENHAGEN, Denmark (AP) — More than 200 years after being sunk by Adm. Horatio Nelson and the British fleet, a Danish warship has been discovered on the seabed of Copenhagen Harbor by marine archaeologists.
Working in thick sediment and almost zero visibility 15 meters (49 feet) beneath the waves, divers are working against the clock to unearth the 19th-century wreck of the Dannebroge before it becomes a construction site in a new housing district being built off the Danish coast.
Denmark’s Viking Ship Museum, which is leading the monthslong underwater excavations, announced its findings on Thursday, 225 years to the day since the Battle of Copenhagen in 1801.
“It’s a big part of the Danish national feeling,” said Morten Johansen, the museum’s head of maritime archaeology.
A great deal has been written about the battle “by very enthusiastic spectators, but we actually don’t know how it was to be onboard a ship being shot to pieces by English warships and some of that story we can probably learn from seeing the wreck, Johansen said.
In the Battle of Copenhagen, Nelson and the British fleet attacked and defeated Denmark’s navy as it formed a protective blockade outside the harbor.
Thousands were killed and wounded during the brutal hourslong naval clash, considered one of Nelson’s “great battles.” The intention was to force Denmark out of an alliance of Northern European powers, including Russia, Prussia and Sweden.
At the center of the fighting was the Danish flagship, the Dannebroge, commanded by Commodore Olfert Fischer.
The 48-meter (157-foot) Dannebroge was Nelson’s main target. Cannon fire tore through its upper deck before incendiary shells sparked a fire aboard.
“(It was) a nightmare to be on board one of these ships,” Johansen said. “When a cannonball hits a ship, it’s not the cannonball that does the most damage to the crew, it’s wooden splinters flying everywhere, very much like grenade debris.”
The battle also is believed to have inspired the phrase “to turn a blind eye.” After deciding to ignore a superior’s signal, Nelson, who had lost sight in his right eye, reportedly remarked: “I have only one eye, I have a right to be blind sometimes.”
Nelson eventually offered a truce and a ceasefire was later agreed with Denmark’s Crown Prince Frederik.
The stricken Dannebroge slowly drifted northward and exploded. Records say the sound created a deafening roar across Copenhagen.
Marine archaeologists have discovered two cannons, uniforms, insignia, shoes, bottles and even part of a sailor’s lower jaw, perhaps one of the 19 unaccounted-for crew members who likely lost their lives that day.
The dig site will soon be enveloped by construction work for Lynetteholm, a megaproject to build a new housing district in the middle of Copenhagen Harbor that is expected to be completed by 2070.
Marine archaeologists began surveying the area late last year, targeting a spot thought to match the flagship’s final position.
Experts say the sizes of the wooden parts found match old drawings. Dendrochronological dating, the method of using tree rings to establish the age of wood, match the year the ship was built. They also say the darkened dig site is full of cannonballs, a hazard for divers navigating waters darkened by clouds of silt stirred up from the seabed.
“Sometimes you can’t see anything, and then you really have to just feel your way, look with your fingers instead of with your eyes,” diver and maritime archaeologist Marie Jonsson said.
Chronicled in books and painted on canvases, the 1801 battle is deeply embedded in Denmark’s national story.
Archaeologists hope their discoveries may help reexamine the event that shaped the Scandinavian country and perhaps uncover personal stories of those who went into battle on that day 225 years ago.
“There are bottles, there are ceramics, and even pieces of basketry,” Jonsson said. “You get closer to the people onboard.”
