Imagine an electric grid powered by clean, renewable energy. Now imagine that this grid provides all the comfort and convenience consumers have come to expect as well as grid reliability and resiliency services that are similar to—or better than—conventional plants. That is the promise of the FlexPower project.

With support from the U.S. Department of Energy Grid Modernization Laboratory Consortium, FlexPower brings National Renewable Energy Laboratory (NREL) researchers together with other National Laboratories to develop a colocated variable hybrid generation power plant enhanced with energy storage at NREL’s Flatirons Campus. Participants include the Idaho National Laboratory (INL) and Sandia National Laboratories (Sandia).

As renewables displace conventional generation, hybrid renewable power plants combined with energy storage can transform variable resources such as wind and solar photovoltaics (PV) into fully dispatchable and flexible energy sources. These hybridized power plants will be capable of operating in day-ahead and real-time energy markets and providing essential reliability and resiliency services to the grid.

Rethinking Renewables

“This research will help accelerate the adoption of utility-scale variable wind and PV resources by demonstrating how hybridization can smooth the transition to clean energy,” said NREL Chief Engineer Vahan Gevorgian. “For the power grid to economically and reliably integrate large amounts of variable renewable generation, it will require robust energy storage capabilities and a rethinking of the value renewable energy assets bring to the grid.”

To support this transformation, researchers will test a variety of energy storage systems, including pumped storage hydropower, battery, hydrogen, flow battery, kinetic, and ultracapacitor energy storage. In addition, the project will focus on advanced control strategies and resource forecast techniques. Sophisticated controls can improve the dispatchability and availability of variable generation by taking advantage of the complementary nature of wind and PV resources and increasing capacity factors for renewable projects with minimum or, in some cases, no additional transmission buildup. Improved forecasting allows hybrid plants to participate in energy and ancillary services markets in the same way conventional generation plants do.

By combining generation, storage, advanced controls, and improved forecasting in hybrid plants, operators can achieve economies of scale by sharing infrastructure as well as siting and permitting costs. These plants can also provide the full spectrum of existing essential reliability services as well as new, evolving grid reliability services. For example, hybrid plants can provide self-black starts as well as power system black starts, can operate in islanded mode, and can participate in power system restoration schemes. And hybrid plants are scalable, ranging from small microgrids to large, interconnected power systems.

The FlexPower project is of great interest to a wide range of stakeholders, including regulators, reliability organizations, system operators, utilities, plant owners and operators, equipment vendors, and island power system owners and operators.

“Hybrid renewable energy plants could introduce the national and global energy sectors to a new and potentially disruptive class of power systems,” Gevorgian said. “The FlexPower project will demonstrate the value of renewable energy assets and suggest strategies for using them more efficiently to reduce curtailment, increase energy production, and smooth variability. The result could be high-value grid services and a more secure and resilient power supply.”

Sharing the Findings

The FlexPower research results will be freely accessible to all stakeholders in the form of public domain information and other assets. Specifically, stakeholders will have access to the FlexPower controller architecture; control codes developed by NREL, INL, and Sandia for industrial control platforms; hybridization-potential assessment maps and databases; results of regional impacts studies; and reports, publications, regional webinars, conference presentations, and other outreach materials.

NREL’s Flatirons Campus grid-scale hybrid system will provide a test bed for companies and researchers to validate and demonstrate their hybrid plant concepts and strategies. The fully operational multi-MW hybrid power plant will be capable of demonstrating all types of dispatchability, reliability, and resiliency services. It will also provide a grid-scale test bed that offers hybrid system demonstrations for a range of stakeholders, opportunities for control and equipment vendors to test new hybrid controls and hardware, a venue for workforce education and new international collaborations, and a validation platform for standardizing hybrid technologies.

FlexPower was funded in part by U.S. Department of Energy’s Wind Energy Technologies OfficeWater Power Technologies OfficeHydrogen and Fuel Cell Technologies Office, and the Office of Electricity.

Hyundai recalls more than 145,000 EVs

Hyundai Motors is recalling 145,235 EVs and other “electrified” vehicles in the US, citing concerns about a loss of driving power, the National Highway Traffic Safety Administration (NHTSA) said on Friday.

The NHTSA announced this morning that the recall affects selected IONIQ 5 and IONIQ 6 EVs, as well as certain luxury Genesis models, including the GV60, GV70, and G80 electrified variants, from the 2022-2025 model years, Reuters reported.

It looks like the issue stems from “the integrated charging control units in these vehicles, which may become damaged and fail to charge the 12-volt battery. This malfunction could lead to a complete loss of drive power, posing safety risks for drivers,” the NHTSA stated.

If you’re an owner of one of these Hyundai models dating 2022-2025, stay tuned. Hyundai has not yet provided a timeline as to when affected vehicles will be repaired.

To make that happen, the company’s dealers will inspect and replace the charging unit and its fuse if necessary, NHTSA said. Free of charge, of course.

Importantly, no crashes, injuries, fatalities, or fires due to this issue have been reported in the US, Hyundai reported.

Tesla brings ‘Actually Smart Summon’ to Europe and Middle East where FSD is limited

Tesla brings 'Actually Smart Summon' to Europe and Middle East where FSD is limited

Tesla announced that ‘Actually Smart Summon,’ its autonomous driving feature that enables moving its vehicles without anyone inside over short distances, is now being launched in Europe and the Middle East.

The automaker’s Full Self-Driving suite of features has been limited in those markets due to regulations and Tesla’s focus on making them work in North America first.

Actually Smart Summon is the vision-only version of Tesla’s “smart summon” feature, which was released years ago on Tesla vehicles with ultrasonic sensors.

When Tesla transitioned away from ultrasonic sensors, Smart Summon was one of the missing features that Tesla had yet to adapt to the vision-only (cameras and neural nets) system.

CEO Elon Musk said that it would be coming in 2022, but it finally came only a few months ago, in 2024.

However, that’s only in North America where Tesla focuses its Full Self-Driving (FSD) development, the feature package that includes Actually Smart Summon, also referred to as ‘ASS’.

Most of Tesla’s other markets, including Europe, don’t have the same capabilities under the Full Self-Driving package. That’s partly due to regulations, but Tesla also focuses on making the features work on North American roads first.

Now, Tesla has announced that its Actually Smart Summon feature is launching in Europe and the Middle East:

The feature can only be used on private roads, like parking lots and driveways. Most people have used it to bring their vehicles parked in a large parking lot to them as they exit a store or restaurant. However, the vehicle moves quite slowly under the feature and the owner needs to keep an eye on it at all time and be ready to cancel the summon as Tesla doesn’t take any responsibility for accidents caused by using Actually Smart Summon., like all other FSD features.

Therefore, most people I know who have the feature, myself included, tried once or try to see or impress some friends who have never seen a car move without anyone inside and then stopped using it.

The feature’s main useful use-case is for people with extremely tight parking spots. It enables them to exit the vehicle before it is in its final parking spot and then move the car in and out remotely.

However, that has been the case for years with the regular Smart Summon, as you generally don’t need the vehicle to handle complex parking lots. You mostly need it to move a few feet forward or backward.

But a recent update has broken this feature for some people. We recently reported on a very unfortunate situation that resulted in a Tesla owner having to get out of his car through his trunk.

Big auto learned its lesson? It’s begging Trump not to blow up emissions rules

Big auto learned its lesson? It's begging Trump not to blow up emissions rules

US Automakers are planning to ask Mr. Trump to retain President Biden’s EPA exhaust rules, in the face of signs that Mr. Trump might try to reverse them. If the rules are reversed, it would cost Americans hundreds of billions of dollars and thousands of deaths per year.

Interestingly, this is the opposite of what big auto did the last time a reality TV show came to the White House – signaling that they have perhaps learned their lesson this time ’round.

First, some history.

In the middle of the 20th century, the effects of human activity on the atmosphere became readily apparent. Certain cities – with Los Angeles among the forefront – were choked by smog, and it was soon found out that vehicle pollution was the primary reason for this smog.

Since Los Angeles was one of the most smog-choked cities, California led the way on clean air regulation, creating the California Air Resources Board in 1967 (under then-Governor Ronald Reagan).

The federal government gave California special dispensation to set stricter regulations than the rest of the country, in recognition that it had a unique smog problem in its primary metropolis. California has retained this dispensation, in the form of a “waiver,” since then. And other states can follow California’s rules, but only if they copy all of the rules exactly.

Thus, there have been two separate sets of clean air regulation in this country since then – the federal rules, and then the “CARB states” which follow California’s rules.

In 2012 that finally changed, when President Obama’s EPA negotiated with California to finally harmonize these standards and also implement higher fuel efficiency nationwide. This would have been a huge boon for both industry and consumers, saving money and giving regulatory certainty to the auto industry.

But then, in 2016, the candidate who got the 2nd most votes in the presidential election was headed for the White House. And automakers responded by immediately lobbying to torpedo these standards, even before inauguration.

Now, you might think that asking a profoundly ignorant individual, who ended up staffing the EPA with bought-and-sold science deniers (huh, that would never happen again would it?), to change rules which had already been set through years of negotiation and lobbying was not a great idea. And you’d be right.

Not long after automakers had the dumb idea to ask an idiot to fix something that wasn’t broken, that idiot went and broke things further, fracturing the agreement between California and the federal government and ensuring less regulatory certainty for automakers.

After realizing their blunder (which they could have avoided by, y’know, thinking at all about it beforehand), big auto relented and asked the government to please not implement the rollbacks automakers had asked for. Some companies even forged their own agreement with California.

But it was too late, and we are now back in the era of disparate regulatory regimes – something which John Bozzella, head of the Alliance for Automotive Innovation (formerly called Global Automakers), keeps complaining about these days, despite having lobbied for exactly this in the first place.

The US EPA and California are still not fully harmonized, but both released recent new standards which do have somewhat similar targets. If a manufacturer builds towards one set of rules, they’ll probably not be too far off from meeting the other.

So in the end, we did get better emissions regulations and California has continued to push forward with clean air regulations, thus signaling a failure on the part of Mr. Trump to cause the long term harm to Americans that he and his oil industry solicitors so desperately seem to desire.

The most recent EPA standards, finalized in March (after being softened at the auto industry’s request), do not mandate any particular powertrain, but rather require steep emissions cuts – and EVs are the easiest way to achieve lower emissions.

Notably, Tesla lobbied in favor of making this last set of standards stronger, and they also lobbied against ruining the Obama/CA standards in 2016 – being one of very few automakers who were on the correct side of that discussion.

Despite that the President Biden EPA’s rules do not mandate any particular powertrain, Mr. Trump, in his usual ignorance, has said that he will end the nonexistent EV mandate. And now that he has received more votes than his opponent for the first time (after three tries, and despite committing treason in 2021 for which there is a clear legal remedy), it looks like the upcoming EPA might be directed to end these emissions cuts and fuel/health cost savings for Americans.

But in this instance, it sounds like the automakers might actually do the right thing for once, and ask the government not to do any rollbacks, and instead let them continue on with the plans without disruption from a convicted felon who seems determined to cede a US EV manufacturing boom back to China.

Detroit’s Big Three automakers – GM, Ford and Stellantis – are all reportedly trying to figure out how to ensure that these rules stay in place. The mentality is that constantly changing regulations are not beneficial for companies – particularly in the auto realm, where models take on the order of 7 years to plan and execute. Long-term planning is important for the hundreds of billions in manufacturing investment that EVs have attracted in the US during Biden’s EV push.

These attitudes are notable, given that this is not what automakers did in 2016/2017. That time, they compulsively pushed for fewer regulations, and now they are asking for regulations to remain in place.

It’s further notable that Tesla CEO Elon Musk, whose company lobbied strongly in favor of emissions cuts and makes more use of the federal EV tax credit than any other company, is now allied with the very entity that’s looking to harm EVs. It seems that we have entered opposite world.

So it remains to be seen where we will go from here – on the one hand, doctorsnursesscientists, environmental groupsmany businessespeople who recognize that they have lungs which they would like to continue using, and so on, generally support the strongest regulation possible. Now, automakers have been added to the pile asking for strong regulations.

On the other hand, a former reality TV host – tagged along with by the CEO of the company that has sold more electric cars than any other – seem determined to kill electric cars, despite the harm that would cause to Americans’ pocketbooks and health insurance premiums. And that famously vindictive character may be even more spurred towards this harmful course of action after failing in his efforts the first time.
