As we trend toward more renewables and distributed energy resources (DERs), the design of the electric distribution system itself imposes physical limitations. These system constraints could lead to issues like overloaded power lines and faults that propagate freely.

But what if we could restructure the underlying system to support greater renewable integration and system resilience? To that end, a National Renewable Energy Laboratory (NREL)–led project is working on a new type of grid device enabled by silicon carbide (SiC) switches and other medium voltage (MV) power electronics that could segment sections of the grid, providing advanced control for flexibility and resilience for our power systems.

The project team is first designing a megawatt-scale prototype converter that provides native “back-to-back” conversion — AC to AC power — at distribution voltages (i.e., not requiring transformers to step down voltage to levels typically used in electronic power conversion). By using MV SiC-based power modules, the converters could be 1/5th the size and 1/10th the weight of alternate equivalent systems, which are trailer-sized and include heavy transformers. Then the team will connect the power converter into NREL’s MV testbed to validate new grid control approaches that the prototype enables.

The project is named “Grid Application Development, Testbed, and Analysis for MV SiC (GADTAMS)” and is funded by the Department of Energy’s Advanced Manufacturing Office.

The NREL-led GADTAMS project is developing and demonstrating smaller and lighter alternatives for direct medium-voltage connections on the grid, which could enable new resilient grid architectures.

“With back-to-back converters between feeders, we can go one step higher in providing resilience across the distribution system,” said Akanksha Singh, a project lead at NREL.

“This technology wasn’t necessary before because we didn’t have so many distributed energy resources on the system, but now we have feeders that are becoming saturated with PV; apart from storage, these feeders don’t have anywhere to inject that excess power,” Singh said. “A new approach to grid interconnection could enable advanced forms of power sharing and provide much-enhanced grid resilience.”

A future grid that features such converters would have the capability to control the flow of power between sections of the grid, shunting excess load or DER-based generation to feeder sections or adjacent circuits as needed, adding new versatility to power distribution. Networked microgrids could protect against the propagation of faults from one microgrid to the next while still allowing controlled power dispatch between the two systems and the macrogrid as well.

During outage recovery, microgrids could be formed that then stabilize neighboring microgrid systems, as envisioned in NREL’s autonomous energy systems research. In general, the two sides of the converter do not need to be synchronized in frequency or even exact voltage level at all — a major shift from the modern power system. But prior to proving any of these applications, NREL and others will first need to build the necessary controls.

“We are developing very novel controls for upcoming grid architectures,” Singh said. “We have local controls on inverters, and we have hierarchical controls that coordinate between grid partitions. With regard to grid support, these controls can do it all: dynamic stability, frequency support, black start, fault ride-through and protection.”

Unlike anything currently available, the NREL testbed provides an environment to validate medium-voltage grid solutions with real power hardware-in-the-loop and real-time grid simulation. For this project, NREL and partners are interested in the full range of use cases for back-to-back SiC converters and have teamed with utility Southern California Edison to inform on utility applications, as well as industry partners General Atomics and Eaton to seek out a commercial path for the technology.

The SiC converter is being built in two halves by project partners Ohio State University and Florida State University. The three-phase converter prototype will be rated for 330 kW and will implement a full thermal and electrical design appropriate for utility use. Traditionally, the same AC-to-AC conversion process requires stepping-down the voltage to low-voltage levels where conventional power electronics can be used, which results in heavy and expensive transformer equipment. The MV SiC option takes advantage of the superior voltage ratings of devices to minimize weight, cost, and size, which makes the technology far more practical and economical for system-wide deployment.

Still, the converter technology is only one aspect of fulfilling flexible interconnections. This framework currently lacks the standardization that exists for so many other recent grid innovations. At NREL, the project team hopes to collect baseline operational data to jumpstart the conversation around how to integrate MV converters in future grids.

“This is a new application that doesn’t exist anywhere yet. We need standards that apply to how the converters can integrate with regular system operation, like starting up, syncing to the grid, etc.,” Singh said. “We are using IEEE Standards 1547 and 2030.8 as a base, interpreting their rules to implement new controls on MV systems. We are trying to merge the two to understand what will apply to this new approach.”

An entirely new grid architecture and operational flexibility could seem far-out for now, but NREL and partners are showing that these options are viable in the near-term and that NREL has the capability to prepare these solutions for real systems. Learn more about how NREL can validate advanced energy systems at scale.

Honda's Prologue electric SUV is taking the US by storm

Honda’s first electric SUV, the Prologue, is already a top-selling EV in the US. With demand picking up, the Honda Prologue is shaping up to be a hit.

Honda Prologue EV sales are picking up in the US

The electric SUV was the fifth best-selling EV in the US, with sales topping 12,600 in the third quarter.

According to Cox Automotive, the Prologue trailed only Tesla’s Model Y, Model 3, Cybertruck, and the Ford Mustang Mach-E.

The performance is impressive, given that Honda didn’t sell a single EV in the US last year. With over 4,100 Prologue’s sold in October, Honda continued outpacing several rivals. The electric SUV outsold the Ford Mustang Mustang Mach-e, which sold 3,313 units in the US last month.

Through October 2024, Honda Prologue sales reached 18,309 in the US, compared to zero last year. Honda began delivering Prologue models in March.

Based on GM’s Ultium platform, the SUV offers up to 296 miles of driving range. Although it uses the same platform as new Chevy, Cadillac, and GMC models, Honda fine-tuned the EV to help it stand out.

The 2024 Honda Prologue EX FWD trim starts at $47,400. With the $7,500 federal tax credit, the electric SUV could be bought for under $40,000 (not including the destination fee).

Electrek’s Take

Although Honda took longer to introduce its first electric SUV in the US, the company is quickly looking to make up ground.

The Prologue, like GM’s new Chevy Equinox and Blazer EVs, is seeing sales surge in the US as new models roll out to dealerships.

Despite headlines claiming EV sales are “slowing” or “cooling,” many automakers, including Honda and GM, are posting record numbers. It isn’t a secret. With long-range models, tech-loaded EVs offered at an affordable price, GM and Honda are proving the demand is there.

Coinbase’s big election bet is about to be tested

Coinbase's big election bet is about to be tested

How Coinbase is looking to drive crypto voters to the polls

WASHINGTON — In the first few years after founding Coinbase, CEO Brian Armstrong shied away from Washington, D.C. But as his ambitions for his crypto exchange scaled, so too did his need to curry favor on Capitol Hill.

“About five or six years ago, we realized that crypto was getting big enough that we needed to go really engage actively in a policy effort, so I started coming out to D.C.,” Armstrong, who started Coinbase in 2012, told CNBC in September, following a day of meetings with political leaders.

Now, it’s practically Armstrong’s full-time job, and Coinbase’s money is all over the nation’s capital. The company was one of the top corporate donors this election cycle, giving more than $75 million to a group called Fairshake and its affiliate PACs, including a fresh pledge of $25 million to support the pro-crypto super PAC in the 2026 midterms. Armstrong personally contributed over $1.3 million to a mix of candidates up and down the ballot.

The tech industry’s biggest names have dotted Washington for years to try and push their agendas as their market caps have expanded, but for Coinbase, the matter is potentially existential.

SEC Chair Gary Gensler sued the firm last year over claims that it sells unregistered securities. A judge has since ruled that the case should be heard by a jury. Coinbase has fought back vociferously, and has also said that it wants to work with regulators to come up with a proper set of laws governing the nascent industry.

Meanwhile, Coinbase faces a growing list of competitors.

In the company’s latest quarterly earnings report last week, Coinbase missed on the top and bottom lines due to lower transaction revenues and a drop in subscription and services revenues. The shares plummeted 15%.

Data from CCData shows the exchange is losing spot market share to industry rivals like Crypto.com. And investors have many new options for accessing bitcoin and ethereum since the SEC greenlit spot funds this year. BlackRock’s ETF chief Samara Cohen told CNBC that 75% of its bitcoin buyers are crypto investors who are new to Wall Street.

Washington can’t save Coinbase from the competition, but the company is betting that, with favorable lawmakers in place, it can be the leader in a thriving industry rather than under the constant threat of lawsuits and Wells notices.

Armstrong said his D.C. visits normally took place once or twice a year. Then it got to be at least a quarterly occasion. And the pace has only increased.

“In the beginning, a lot of people didn’t know what crypto was,” Armstrong said of his earlier trips. Now, “the discussion has advanced, really, to, how do we pass clear rules, create legislation in the United States?”

Coinbase's legal chief on crypto's 2024 election spending

An SEC sans Chair Gensler

Paul Grewal, Coinbase’s chief legal officer, attended a fundraiser in San Francisco in June that raised $12 million for former President Donald Trump. It was hosted by venture capitalist David Sacks, a former Trump critic who became an outspoken supporter when he became the Republican nominee.

Grewal later joined a fundraiser in Nashville in July for the former president.

Trump has never shown much of an aptitude for the nuances of crypto, but he’s welcomed the industry’s financial support. He was applauded in the summer, when he vowed to fire Gensler as head of the SEC if he wins.

Grewal told CNBC that he’s had “many conversations” behind closed doors with both the Trump camp as well as Democratic Vice President Kamala Harris’ campaign. Heading into Election Day on Tuesday, the candidates were in a virtual dead-heat.

“What I think we’re hearing from both campaigns is they get it,” Grewal said. “They understand that in swing state after swing state, there are enough voters who care about crypto that the candidate and their campaigns need to give voice to the concerns of those voters in supporting sensible rules for crypto, sensible legislation coming out of Congress, and that’s very encouraging.”

Grewal said that Trump “came earlier to this pro-crypto view,” but said that Harris recognizes the need for “an agenda focused on promoting sensible rules for crypto as much as any other technology.”

But Coinbase has stayed out of the presidential contest and focused its finances exclusively on Congressional races, as the company looks to help assemble a group of lawmakers with favorable views of the industry.

The Stand With Crypto Alliance, launched by Coinbase last year, has developed a grading system for House and Senate candidates across the country.

In the Ohio Senate race, for example, the organization gives Democratic incumbent Sen. Sherrod Brown, who chairs the banking committee, an “F” grade, versus an “A” grade for his Republican rival Bernie Moreno, a blockchain entrepreneur. Some $40 million of crypto money has been directed at defeating Brown, and one PAC has paid for five ads designed to boost awareness of Moreno. The race is very close and is crucial in determining which party will control the Senate.

Stand with Crypto, which has enrolled 1.4 million advocates across the country, is also working to mobilize digital asset owners living in swing states. This effort involved a cross-country bus tour through battlegrounds focused on getting these residents registered to vote.

Crypto climbs and bitcoin nears all-time high ahead of U.S. election

“It’s really extraordinary, given how razor-thin the margin of victory was in the 2020 election, to see crypto not only be an issue, but potentially a determinative issue in terms of the presidential cycle,” Faryar Shirzad, Coinbase’s chief policy officer, said in an interview.

Shirzad said that last year, he and his team concluded that the only way to get politics out of crypto was “to build our own political operation.” He said the goal is to “neutralization the politicization of the crypto issue and talk about it on the merits.”

Coinbase is far from alone. Nearly half of all corporate money raised this election comes from crypto firms.

Fairshake, one of the top spending PACs this cycle, told CNBC it’s raised around $170 million this election and disbursed approximately $135 million.

Ripple Labs is another one of Fairshake’s top political donors.

The company, which has spent more than $100 million battling Gensler, has given around $50 million to Fairshake. Several executives have also contributed to a mix of Democratic and Republican candidates in races across the country.

Ripple’s head of U.S. public policy, Lauren Belive, told CNBC at a fintech conference in Las Vegas that the company was motivated by the SEC’s overreach.

“We really wanted to put people into office that could learn about this technology and understand this technology, because we need Congress to act and to create federal statutes and not have this enforcement regime,” said Belive. She added the regulator has issued over 100 enforcement actions against crypto-aligned companies.

No backing down on CO2 targets, says EU’s next transport head

No backing down on CO2 targets, says EU's next transport head

The next European commissioner for sustainable transport drew a hard line in a hearing this week: Apostolos Tzitzikostas backs e-mobility and has no intention of watering down the EU’s plan to ban new registrations for ICE cars in 2035. Problem is, it’s not clear how he aims to make this happen.

At an hours-long hearing Monday before the Transport Committee, live-reported by Politico, the man designated the take the top seat in transport as EU commissioner, Greek politician Apostolos Tzitzikostas, clearly talked the talk. He held firm that he won’t delay next year’s emission targets, regardless of relentless pressures from the automobile industry.

“We have specific rules and goals that we want … and we have to stick to the plan. Otherwise the message the European Union will convey … is not a message of stability and trust,” he was quoted as saying via Politico. “We know very well that the technology is going forward.”

What about Europe’s automobile industry, which employs 14 million people across the bloc and is deep in crisis mode and facing a potential 15 billion euros a year in fines by failing to meet the CO2 targets? Profits are tanking, factories are closing, and European automakers are losing dominance to Chinese competition. Don’t worry, Tzitzikostas said. He will offer a full-scale plan early in his tenure, so we’ll just have to wait and see what this means: more restrictions on Chinese-made vehicles, more government subsidies on electric vehicles?

“We have to make everything in our power to make [the car sector] survive,” Tzitzikostas said. “The automotive industrial plan will give answers to all these skepticisms you might have.”

“There is no reason to be worried.” Hmm, vagueness isn’t very comforting, I’m sure.

However, one solution put on the table was the EU’s support of all-electric company fleets, which account for half of all new registrations across the EU. Doing so would also create a second-hand market in EVs in that most company fleets are purchased by lease, so cars are replaced a few years later. “I can’t say if it would be done by incentives or taxation, but I can’t exclude legislative action.”

From 2035, cars emitting CO2 may not be registered in the EU, which was put in place by Commission President Ursula von der Leyen’s “Green Deal” during her first term in office. To secure a majority vote for her second term, she called for an exemption for combustion engines that are operated with e-fuels. One thing that was clear from the hearing is that Tzitzikostas too supports that position, and wants e-fuels to be included in legislation up for review in 2026.

The future commissioner also wants to drive investment and solutions into sustainable transport, looking into greener air travel by scaling greener fuels, and making rail travel more attractive by allowing rail travelers to use a single ticket and booking system for cross-border train journeys. Lest the automobile industry panic even further, Tzitzikostas added that he does not want to lose sight of road transport and helping European carmakers make the shift to electric vehicles. But again, no details here.

“Commissioner-designate Tzitzikostas talked a good game about cleaning up Europe’s top polluter, transport,” said William Todts, executive director of T&E in a statement. “He showed commitment to e-mobility, scaling clean fuels for aviation and shipping, and solving rail ticketing. But he said very little about what exactly he would do when appointed Commissioner. His repeated refusal to commit to a much anticipated EU law to electrify corporate car fleets was bewildering.”

Still, it’s early days for Tzitzikostas, whose closing remarks, after more than three hours of grilling by MEPs, got a hearty round of applause. His confirmation vote quickly followed, so the tough job of handling Europe’s green transition will soon be all his.
