The U.S. Department of Energy said $35 million in funding would be made available “to advance tidal and river current energy systems” under plans it hopes will provide a shot in the arm to a sector whose current footprint is tiny.

In a statement Tuesday outlining the move, the DOE said the funding opportunity — which is slated for release in 2023 — represented the “largest investment in tidal and river current energy technologies in the United States.”

A notice of intent related to the funding opportunity has been posted online. The DOE said it proposed “to develop a tidal or river current research, development, and demonstration site and to support in-water demonstration of at least one tidal energy system.”

Alejandro Moreno, who is acting assistant secretary for Energy Efficiency and Renewable Energy, said oceans and rivers represented “a huge potential source of renewable energy.” The DOE said the funding would come from the Bipartisan Infrastructure Law.

Over the past few years a number of projects related to tidal power, including ones in the United States, have taken significant steps forward.

In July 2021, for instance, a tidal turbine dubbed “the world’s most powerful” started grid-connected power generation at the European Marine Energy Centre in Orkney, an archipelago located north of mainland Scotland.

In May 2022, a £4.6 million (around $5.18 million) facility that can test tidal turbine blades under strenuous conditions was officially opened, with those behind it hoping it will accelerate the development of marine energy technology and lower costs.

While there is excitement about the potential of renewable technologies such as tidal power, there are significant challenges when it comes to scaling up, a point the DOE acknowledged in its announcement.

“The U.S. tidal and river current energy industry requires long-term and substantial funding to move from testing devices one at a time to establishing a commercial site,” it said.

“The complexity of installing devices and navigating permitting processes, combined with a lack of connection to local power grids, have proven to be a consistent barrier to advancing tidal and river current energy.”

Today, America’s electricity generation mix remains heavily reliant on fossil fuels.  

According to preliminary figures from the U.S. Energy Information Administration, in 2021 fossil fuels’ share of utility-scale electricity generation was 60.8%. By contrast, renewables’ share stood at 20.1%, while nuclear accounted for 18.9%.

While tidal barrage developments were the initial focus of those operating in the marine energy industry — EDF’s La Rance tidal barrage dates back to the 1960s, for example — recent years have seen companies focus their attention on different systems.

These include tidal stream devices which, the European Marine Energy Centre says, “are broadly similar to submerged wind turbines.” Compared to other renewables, the overall size of tidal stream and wave energy projects is very small.

In data released in March 2022, Ocean Energy Europe said 2.2 MW of tidal stream capacity was installed in Europe last year, compared to just 260 kilowatts in 2020.

For wave energy, 681 kW was installed, which OEE said was a threefold increase. Globally, 1.38 MW of wave energy came online in 2021, while 3.12 MW of tidal stream capacity was installed.

By way of comparison, Europe installed 17.4 gigawatts of wind power capacity in 2021, according to figures from industry body WindEurope.

Workhorse electric delivery vans arrive in Canada this spring

Following approval from Transport Canada, EV startup Workhorse will be bringing the W56 and W750 model electric delivery vans to commercial truck dealers in Canada as early as this spring.

Workhorse first showed its W56 medium-duty electric truck at Indiana’s Work Truck Week in 2023, and has sold the trucks to logistics and delivery companies like FedEx and Pride Group – which ordered more than six thousand of the electric vans in 2021, and continues to expand its fleet.

“This is a major step forward for Workhorse,” says Josh Anderson, Workhorse’s chief technology officer in a press statement. “Pre-clearance from Transport Canada opens up a large new market for our products throughout Canada, including with fleets that operate across borders in North America.”

As part of the approval process, Workhorse completed its registration as a foreign manufacturer under Transport Canada’s Appendix G clearance program. Transport Canada confirmed the vans’ compliance with Canadian Motor Vehicle Safety Standards (CMVSS) for both vehicles – but it remains to be seen if and how the latest tariff-driven trade war between the Trump Administration’s US and Canada will impact Workhorse’s plans to expand throughout North America.

Despite that uncertainty, Workhorse execs remain upbeat. “We’re excited that our electric step vans can now reach Canadian roads and highways, providing reliable, zero-emission solutions that customers can depend on,” added Anderson.

Canadian pricing has yet to be announced.

There’s no other way to say it: the Trump/Musk co-presidency is disrupting a lot of companies’ plans – and that’s especially true across North American borders. But in all this chaos and turmoil there undoubtedly lies opportunity, and it will be interesting to see who ends up on top.

Liebherr developing giant, 140-ton Segway-style autonomous haulers [video]

Liebherr developing giant, 140-ton Segway-style autonomous haulers [video]

The new Liebherr S1 Vision 140-ton hauler is unlike any heavy haul truck currently on the market – primarily because the giant, self-propelled, single-axle autonomous bucket doesn’t look anything like any truck you’ve ever seen.

Liebherr says its latest heavy equipment concept was born from a desire to rethink truck design with a focus only on core functions. The resulting S1 Vision is primarily just a single axle with two powerful electric motors sending power to a pair of massive airless tires designed carry loads up to 131 tonnes (just over 140 tons).

The design enables rapid maintenance, as important components easily accessible for quick servicing. Wear parts can be replaced efficiently, and the electric drive significantly reduces maintenance work. This helps to minimise downtimes and increases operational efficiency.

LIEBHERR

Because of its versatility, durability, and ability to perform zero-turn maneuvers that other equipment simply can’t, the Liebherr S1 Vision can be adapted for various applications, including earthmoving, mining, and even agriculture. There’s also a nonzero chance of this technology finding applications supporting other on-site equipment through charging or fuel delivery.

The S1 accomplishes that trick safely with the help of an automatic load leveling system that ensures maximum stability, even on bumpy or rough terrain. The company says this technology significantly reduces the risk of tipping while providing smooth and secure operation across various environments.

Liebherr will show the S1 Vision at this year’s bauma equipment exhibition in Munich, Germany. The design has already been nominated for the bauma Innovation Award in the Mechanical Engineering category – and my money’s on it winning.

Electrek’s Take

This is such goofy, stupid fun that if it was wheelbarrow-sized I’d have three of them. I can’t imagine the insanity of watching one of these things roll across a job site with 100 tons of granite in the bucket – and will have nightmares about the kind of damage it could do if it flipped out like a poorly made Chinese hoverboard clone whipping a toddler across a living room … which, in fairness, would probably get a billion views on Instagram or TikTok or whatever.

I can’t wait.

Meet the newest EV from Hyundai – new HX19e electric excavator

The HD arm of Hyundai has just released the first official images of the new, battery-electric HX19e mini excavator – the first ever production electric excavator from the global South Korean manufacturer.

The HX19e will be the first all-electric asset to enter series production at Hyundai Construction Equipment, with manufacturing set to begin this April.

The new HX19e will be offered with either a 32 kWh or 40 kWh li-ion battery pack – which, according to Hyundai, is nearly double the capacity offered by its nearest competitor (pretty sure that’s not correct –Ed.). The 40kWh battery allows for up to 6 hours and 40 minutes of continuous operation between charges, with a break time top-up on delivering full shift usability.

Those batteries send power to a 13 kW (17.5 hp) electric motor that drives an open-center hydraulic system. Hyundai claims the system delivers job site performance that is at least equal to, if not better than, that of its diesel-powered HX19A mini excavator.

To that end, the Hyundai XH19e offers the same 16 kN bucket breakout force and a slightly higher 9.4 kN (just over 2100 lb-ft) dipper arm breakout force. The maximum digging depth is 7.6 feet, and the maximum digging reach is 12.9 feet. Hyundai will offer the new electric excavator with just four selectable options:

  • enclosed cab vs. open canopy
  • 32 or 40 kWh battery capacity

All HX19es will ship with a high standard specification that includes safety valves on the main boom, dipper arm, and dozer blade hydraulic cylinders, as well as two-way auxiliary hydraulic piping allows the machine to be used with a range of commercially available implements. The hydraulics needed to operate a quick coupler, LED booms lights, rotating beacons, an MP3 radio with USB connectivity, and an operator’s seat with mechanical suspension are also standard.

Like its counterparts at Volvo CE, the new Hyundai excavator uses automotive-style charging ports to take advantage of existing infrastructure at fleet depots and public charging stations. More detailed specifications, dimensions, and pricing should be announced by bauma.

Electrek’s Take

The ability to operate indoors, underground, or in environments like zoos and hospitals were keeping noise levels down is of critical importance to the success of an operation makes electric equipment assets like these coming from Hyundai a must-have for fleet operators and construction crews that hope to remain competitive in the face of ever-increasing noise regulations. The fact that these are cleaner, safer, and cheaper to operate is just icing on that cake.
