UK sets new record for wind power generation

Electrified Trucking Grid Integration explores vehicle-to-grid (V2G) strategies where rolling batteries backfeed power during peak demand, optimizing charging infrastructure, time-of-use pricing, and IESO market operations for Ontario shippers like Nature Fresh Farms.

Key Points

An approach using V2G-enabled electric trucks to support the grid, cut peak costs, and add revenue streams.

✅ Models charging sites, timing, and local grid impacts.

✅ Evaluates V2G backfeed economics and IESO pricing.

✅ Uses Nature Fresh Farms data for logistics and energy.

A University of Windsor project will study whether an electrified trucking industry might not only deliver the goods, but help keep the lights on with the timely off-loading of excess electrons from their powerful batteries via vehicle-to-grid approaches now emerging.

The two-year study is being overseen by Environmental Energy Institute director Rupp Carriveau and associate professor Hanna Moah of the Cross-Border Institute in conjunction with the Leamington-based greenhouse grower Nature Fresh Farms.

“The study will look at what happens if we electrified the transport truck fleet in Ontario to different degrees, considering the power demand for truck fleets that would result,” Carriveau said.

“Where trucks would be charging and how that will affect the electricity grid grid coordination in those locations at specific times. We’ll be able to identify peak times on the demand side.

“On the other side, we have to recognize these are rolling batteries. They may be able to backfeed the grid, sell electricity back to prop the grid up in locations it wasn’t able to in the past.”

The national research organization Mathematics of International Technology and Complex Systems (Mitacs) is funding the $160,000 study, and the Independent Electricity Systems Operator, a Crown corporation responsible for operating Ontario’s electricity market, amid an electricity supply crunch that is boosting storage efforts, is also offering support for the project.

Because of the varying electricity prices in the province based on usage, peak demand and even time of year, Carriveau said there could be times where draining off excess truck battery power will be cheaper than the grid, and vehicle-to-building charging models show how those savings can be realized.

“It could offer the truck owner another revenue stream from his asset, and businesses a cheaper electricity alternative in certain circumstances,” he said.

The local greenhouse industry was a natural fit for the study, said Carriveau, based on the amount of work the university does with the sector along with the fact it is both a large consumer and producer of electricity.

The study will be based on assumptions for electric truck capacity and performance because the low number of such vehicles currently on the road, though large electric bus fleets offer operational insights.

How will an electrified trucking industry affect Ontario’s electricity grid? University of Windsor engineering professor Rupp Carriveau is part of a new study on trucks being used to help deliver electricity as well as their products around Ontario. He is shown on campus on Tuesday, July 6, 2021.

Nature Fresh Farms will supply all its data on power use, logistics, utility costs and shipping schedules to determine if switching to an electrified fleet makes sense for the company.

“As an innovative company, we are always thinking, ‘What is next?’, whether its developments in product varieties, technology or sustainability,” said company CEO Peter Quiring. “Green transportation is the next big focus.

“We were given the opportunity to work closely on this project and offer our operations as a case study to see how we can find feasible alternatives, not only for Nature Fresh Farms or even for companies in agriculture, but for every industry that relies on the transportation of their goods.”

Currently, Nature Fresh Farms doesn’t have any electrified trucks. Carriveau said the second phase of the study might actually involve an electric truck in a pilot project.

Germany Hydrogen Fuel Cell Market gains momentum as policy, mobility, and R&D align; National Hydrogen Strategy, regulatory frameworks, and cost-of-ownership advances boost heavy transport, while Europe races Asia amid battery-electric competition and infrastructure scale-up.

Key Points

It is Germany and Europe's hydrogen fuel cell ecosystem across policy, costs, R&D, and mobility and freight deployments.

✅ Policy support via National Hydrogen Strategy and tax incentives

✅ TCO parity improves for heavy transport vs other low-emission tech

✅ R&D targets higher temps, compactness for road, rail, sea, air

In a new report examining the status of the German and European hydrogen fuel cell markets, the German government-backed National Platform Future of Mobility (NPM) says there is “a good chance that fuel cell technology can achieve a break-through in mobile applications,” even as the age of electric cars accelerates across markets.

However, Europe must catch up with Asian countries, it adds, even as a push for electricity shapes climate policy. For Germany and Europe to take on a leading role in fuel cell technologies, their industries need to be strengthened and sustainably developed, the report finds. In its paper, the NPM Working Group 4 – which aims to secure Germany as a place for mobility, battery cell production, recycling, training and qualification – states that the “chances of fuel cell technology achieving a break-through in the automotive industry – even in Europe – are better than ever,” echoing recent remarks from BMW's chief about hydrogen's appeal.

The development, expansion and use of the technology in various applications are now supported by “a significantly modified regulatory framework and new political ambitions, as stipulated in the National Hydrogen Strategy,” while updated forecasts show e-mobility driving electricity demand in Germany, the report stresses. In terms of cost of ownership, “hydrogen solutions can hold their own compared to other technologies” and there are “many promising developments in the transport sector, especially in heavy transport.”

If research and development efforts can help optimise installation space and weight as well as increase the operating temperature of fuel cells, hydrogen solutions can also become attractive for maritime, rail and air transport, even as other electrochemical approaches, such as flow battery cars, progress, the report notes. Tax incentives -- such as the Renewable Energy Sources Act (EEG) surcharge exemption for green hydrogen -- can contribute to the technology’s appeal, it adds.

Fuel cell drives are often seen as a way to decarbonise certain areas of transport, such as heavy trucks. However, producing the hydrogen in a sustainable way consumes a lot of renewable electricity that power companies must supply in other sectors, and experts say electricity vs hydrogen trade-offs favor battery-electric trucks because they are much cheaper to run than other low-emission technologies, including fuel cells.

Tidal Energy harnesses ocean currents with tidal turbines to deliver predictable, renewable power. From Scotland's Orkney to New York's East River, clean baseload electricity complements wind and solar in decarbonizing grids.

Key Points

Tidal energy uses underwater turbines to capture predictable ocean currents, delivering reliable, low-carbon power.

✅ Predictable 2-way flows enable forecastable baseload

✅ Higher energy density than wind, slower flow speeds

✅ Costs remain high; scaling and deployment are challenging

As the world looks to curb climate change and reduce fossil fuel emissions, some companies are focusing on a relatively untapped but vast and abundant source of energy — tidal waves.

On opposite sides of the Atlantic, two firms are working to harness ocean currents in different ways to try to generate reliable clean energy.

Off the coast of Scotland, Orbital Marine Power operates what it says is the "most powerful tidal turbine in the world." The turbine is approximately the size of a passenger airplane and even looks similar, with its central platform floating on the water and two wings extending downwards on either side. At the ends of each wing, about 60 feet below the surface, are large rotors whose movement is dictated by the waves.

"The energy itself of tidal streams is familiar to people, it's kinetic energy, so it's not too dissimilar to something like wind," Andrew Scott, Orbital's CEO, told CNN Business. "The bits of technology that generate power look not too different to a wind turbine."

But there are some key differences to wind energy, primarily that waves are far more predictable than winds. The ebb and flow of tides rarely differs significantly and can be timed far more precisely.

Orbital Marine Power's floating turbines off the Scottish coast produce enough energy to power 2,000 homes a year, while another Scottish tidal project recently produced enough for nearly 4,000 homes.

Orbital Marine Power's floating turbines off the Scottish coast produce enough energy to power 2,000 homes a year.

"You can predict those motions years and decades [in] advance," Scott said. "But also from a direction perspective, they only really come from two directions and they're almost 180 degrees," he added, unlike wind turbines that must account for wind from several different directions at once.

Tidal waves are also capable of generating more energy than wind, Scott says.

"Seawater is 800 times the density of wind," he said. "So the flow speeds are far slower, but they generate far more energy."

The Orbital turbine, which is connected to the electricity grid in Scotland's Orkney, can produce up to two megawatts — enough to power 2,000 homes a year — according to the company.

Scott acknowledges that the technology isn't fully mainstream yet and some challenges remain including the high cost of the technology, but the reliability and potential of tidal energy could make it a useful tool in the fight against climate change, as projects like Sustainable Marine in Nova Scotia begin delivering power to the grid.

"It is becoming increasingly apparent that ... climate change is not going to be solved with one silver bullet," he said.

'Could be 24/7 power'
Around 3,000 miles away from Orbital's turbines, Verdant Power is using similar technology to generate power near Roosevelt Island in New York City's East River. Although not on the market yet, Verdant's turbines set up as part of a pilot project help supply electricity to New York's grid. But rather than float near the surface, they're mounted on a frame that's lowered to the bottom of the river.

"The best way to envision what Verdant Power's technology is, is to think of wind turbines underwater," the company's founder, Trey Taylor, told CNN Business. And river currents tend to provide the same advantages for energy generation as ocean currents, he explained (though the East River is also connected to the Atlantic).

"What's nice about our rivers and systems is that could be 24/7 power," he said, even as U.S. offshore wind aims to compete with gas. "Not to ding wind or solar, but the wind doesn't always blow and the sun doesn't always shine. But river currents, depending on the river, could be 24/7."

Verdant Power helps supply electricity to New York City
Over the course of eight months, Verdant has generated enough electricity to power roughly 60 homes — though Taylor says a full-fledged power plant built on its technology could generate enough for 6,000 homes. And by his estimate, the global capacity for tidal energy is enormous, with regions like the Bay of Fundy pursuing new attempts around Nova Scotia.

A costly technology
The biggest obstacle to reaching that goal at the moment is how expensive it is to set up and scale up tidal power systems.

"Generating electricity from ocean waves is not the challenge, the challenge is doing it in a cost-effective way that people are willing to pay for that competes with ... other sources of energy," said Jesse Roberts, Environmental Analysis Lead at the US government-affiliated Sandia National Laboratories. "The added cost of going out into the ocean and deploying in the ocean... that's very expensive to do," he added. According to 2019 figures from the US Department of Energy, the average commercial tidal energy project costs as much as $280 per megawatt hour. Wind energy, by comparison, currently costs roughly $20 per megawatt hour and is "one of the lowest-priced energy sources available today," with major additions like the UK's biggest offshore wind farm starting to supply the grid, according to the agency.

When operational, the Orbital turbine's wing blades drop below the surface of the water and generate power from ocean currents.

When operational, the Orbital turbine's wing blades drop below the surface of the water and generate power from ocean currents.

Roberts estimates that tidal energy is two or three decades behind wind energy in terms of adoption and scale.

The costs and challenges of operating underwater are something both Scott and Taylor acknowledge.
"Solar and wind are above ground. It's easy to work with stuff that you can see," Taylor said. "We're underwater, and it's probably easier to get a rocket to the moon than to get these to work underwater."
But the goal of tidal power is not so much to compete with those two energy sources as it is to grow the overall pie, alongside innovations such as gravity power that can help decarbonize grids.

"The low hanging fruit of solar and wind were quite obvious," Scott said. "But do they have to be the only solution? Is there room for other solutions? I think when the energy source is there, and you can develop technologies that can harness it, then absolutely."

Utility-Controlled EV Charging shapes who builds charging stations as utilities, regulators, and private networks compete over infrastructure, grid upgrades, and pricing, impacting ratepayers, competition, and EV adoption across states seeking cleaner transport.

Key Points

Utility-controlled EV charging is utilities building charging networks affecting rates, competition and grid costs.

✅ Regulated investment may raise rates before broader savings.

✅ Private firms warn monopolies stifle competition and innovation.

✅ Regulators balance access, equity, and grid upgrade needs.

Electric vehicles are widely seen as the automobile industry’s future, but a battle is unfolding in states across America over who should control the charging stations that could gradually replace fuel pumps.

From Exelon Corp. to Southern California Edison, utilities have sought regulatory approval to invest millions of dollars in upgrading their infrastructure as state power grids adapt to increased charging demand, and, in some cases, to own and operate chargers.

The proposals are sparking concerns from consumer advocates about higher electric rates and oil companies about subsidizing rivals. They are also drawing opposition from startups that say the successors to gas stations should be open to private-sector competition, not controlled by monopoly utilities.

That debate is playing out in regulatory commissions throughout the U.S. as states and utilities promote wider adoption of electric vehicles. At stake are charging infrastructure investments expected to total more than $13 billion over the next five years, as an American EV boom accelerates, according to energy consulting firm Wood Mackenzie. That would cover roughly 3.2 million charging outlets.

Calvin Butler Jr., who leads Exelon’s utilities business, said many states have grown more open to the idea of utilities becoming bigger players in charging as electric vehicles have struggled to take off in the U.S., where they make up only around 2% of new car sales.

“When the utilities are engaged, there’s quicker adoption because the infrastructure is there,” he said.

Major auto makers including General Motors Co. and Ford Motor Co. are accelerating production of electric vehicles, and models like Tesla’s Model 3 are shaping utility planning, and a number of states have set ambitious EV goals—most recently California, which aims to ban the sale of new gasoline-powered cars by 2035. But a patchy charging-station network remains a huge impediment to mass EV adoption.

Democratic presidential candidate Joe Biden has called for building more than 500,000 new public charging outlets in a decade as part of his plan to combat climate change, amid Biden’s push to electrify the transportation sector. But exactly how that would happen is unclear. The U.S. currently has fewer than 100,000 public outlets, according to the Energy Department. President Trump, who has weakened federal tailpipe emissions targets, hasn’t put forward an electric-vehicle charging plan, though he backed a 2019 transportation bill that would have provided $1 billion in grants to build alternative fueling infrastructure, including for electric vehicles.

Charging access currently varies widely by state, as does utility involvement, with many utilities bullish course on EV charging to support growth, which can range from providing rebates on home chargers to preparing sites for public charging—and even owning and operating the equipment needed to juice up electric vehicles.

As of September, regulators in 24 states had signed off on roughly $2.6 billion of utility investment in transportation electrification, according to Atlas Public Policy, a Washington, D.C., policy firm. More than half of that spending was authorized in California, where electric vehicle adoption is highest.

Nearly a decade ago, California blocked utilities from owning most charging equipment, citing concerns about potentially stifling competition. But the nation’s most populous state reversed course in 2014, seeking to spur electrification.

Regulators across the country have since been wrestling with similar questions, generating a patchwork of rules.

Maryland regulators signed off last year on a pilot program allowing subsidiaries of Exelon and FirstEnergy Corp. to own and operate public charging stations on government property, provided that the drivers who use them cover at least some of the costs.

Months later, the District of Columbia rejected an Exelon subsidiary’s request to own public chargers, saying independent charging companies had it covered.

Some charging firms argue utilities shouldn’t be given monopolies on car charging, though they might need to play a role in connecting rural customers and building stations where they would otherwise be uneconomical.

“Maybe the utility should be the supplier of last resort,” said Cathy Zoi, chief executive of charging network EVgo Services LLC, which operates more than 800 charging stations in 34 states.

Utility charging investments generally are expected to raise customers’ electricity bills, at least initially. California recently approved the largest charging program by a single utility to date: a $436 million initiative by Southern California Edison, an arm of Edison International, as the state also explores grid stability opportunities from EVs. The company said it expects the program to increase the average residential customer’s bill by around 50 cents a month.

But utilities and other advocates of electrification point to studies indicating greater EV adoption could help reduce electricity rates over time, by giving utilities more revenue to help cover system upgrades.

Proponents of having utilities build charging networks also argue that they have the scale to do so more quickly, which would lead to faster EV adoption and environmental improvements such as lower greenhouse gas emissions and cleaner air. While the investments most directly help EV owners, “they accrue immediate benefits for everyone,” said Jill Anderson, a Southern California Edison senior vice president.

Some consumer advocates are wary of approving extensive utility investment in charging, citing the cost to ratepayers.

“It’s like, ‘Pay me now, and maybe someday your rates will be less,’” said Stefanie Brand, who advocates on behalf of ratepayers for the state of New Jersey, where regulators have yet to sign off on any utility proposals to invest in electric vehicle charging. “I don’t think it makes sense to build it hoping that they will come.”

Groups representing oil-and-gas companies, which stand to lose market share as people embrace electric vehicles, also have criticized utility charging proposals.

“These utilities should not be able to use their monopoly power to use all of their customers’ resources to build investments that definitely won’t benefit everybody, and may or may not be economical at this point,” said Derrick Morgan, who leads federal and regulatory affairs at the American Fuel & Petrochemical Manufacturers, a trade organization.

Utility executives said their companies have long been used to further government policy objectives deemed to be in the public interest, drawing on lessons from 2021 to guide next steps, such as improving energy efficiency.

“This isn’t just about letting market forces work,” said Mike Calviou, senior vice president for strategy and regulation at National Grid PLC’s U.S. division.

U.S. Renewable Energy Forecast 2024 will see wind and solar power surpass one-fourth of electricity generation, EIA projects, as coal declines, natural gas dips, and clean energy capacity, grid integration, and policy incentives expand.

Key Points

EIA outlook: renewables at 26% of U.S. power in 2024, led by wind and solar as coal declines and gas share dips.

✅ Wind and solar hit 18% combined, surpassing coal's 17%.

✅ Natural gas dips to 37% as demand rebounds modestly.

✅ Coal plant closures accelerate amid costs, emissions, and age.

Renewable energy is poised to reach a milestone, after a record 28% in April this year, as a new government report projects that wind, solar and other renewable sources will exceed one-fourth of the country’s electricity generation for the first time, in 2024.

This is one of the many takeaways from the federal government’s Short Term Energy Outlook, a monthly report whose new edition is the first to include a forecast for 2024. The report’s authors in the Energy Information Administration are expecting renewables to increase in market share, while natural gas and coal would both decrease.

From 2023 to 2024, renewables would rise from 24 percent to 26 percent of U.S. electricity generation; coal’s share would drop from 18 percent to 17 percent; gas would remain the leader but drop from 38 percent to 37 percent; and nuclear would be unchanged at 19 percent.

It was a big deal in 2020 when generation from renewables passed coal for the first time in 130 years over a full year. Coal made a comeback in 2021 and then retreated again in 2022 as renewables surpassed coal in generation. The ups and downs were largely the result of fluctuations in electricity demand during and then after the Covid-19 pandemic.

The new report indicates that coal doesn’t have another comeback in the works. This fuel, which was the country’s leading electricity source less than a decade ago, is declining as many coal-fired power plants are old and economically uncompetitive. Coal plants continue to close, and developers aren’t building new ones because of concerns about high costs and emissions, a trend underscored when renewables became the second-most prevalent source in 2020 across the U.S.

The growth in renewable energy is coming from wind and solar power, with wind responsible for about one-third of the growth and solar accounting for two-thirds, the report says, and combined output from wind and solar has already exceeded nuclear for the first time in the U.S. Other renewable sources, like hydropower and biomass, would be flat.

In fact, the growth of wind and solar is projected to be so swift that the combination of just those two sources would be 18 percent of the U.S. total by 2024, which would surpass coal’s 17 percent.

A key variable is overall electricity consumption. EIA is projecting that this will fall 1 percent in 2023 compared to 2022, due a mild summer. Then, consumption will increase 1 percent in 2024.

If demand was rising more, then natural gas power would likely gain market share because of gas power plants’ ability to vary their output as needed to respond to changes in demand.

I asked Eric Gimon, a senior fellow at the think tank Energy Innovation, what he thinks of these latest numbers.

He said wind and solar have gotten so big that it almost makes sense to track them as their own categories as opposed to lumping them into the larger category of renewables. He expects that the government will do this sometime soon.

Also, he thinks the projected increases for wind and solar, while substantial, are still smaller than those resources are likely to grow.

“My experience over the last 10 years is that the EIA tends to have flattish forecasts,” he said, meaning the federal office has underestimated the actual growth.

Some energy analysts have criticized EIA for being slow to recognize the growth of renewables. But much of the criticism is about the Annual Energy Outlook, which has numbers going out to mid-century, even as the U.S. is moving toward 30% from wind and solar by the end of the decade. The Short Term Energy Outlook, with numbers going one year into the future, has been more reliable.

Gimon said EIA is “kind of like your conservative uncle” in its forecasts, so it’s notable that the office expects to see a significant uptick in wind and solar.

Even so, he thinks the latest Short Term Energy Outlook should be read as the lower end of the range of potential increase for wind and solar.

For him to be right, the wind and solar industries will need to figure out solutions to the challenges they’ve been having in obtaining parts; they will need to make progress in dealing with local opposition to many projects and in having enough interstate power lines to deliver the electricity. And, new policies like the Inflation Reduction Act will need to have their desired effect of encouraging projects through the use of tax incentives.

It’s not much of a stretch to imagine that clean energy industries will make some progress on all of those fronts.

US Renewable Energy Cost Advantage signals cheaper utility-scale solar and onshore wind versus natural gas, with LCOE declines, tax credits, and climate policy cutting electricity costs for utilities and grids across the United States.

Key Points

Cheaper solar and wind than natural gas, driven by LCOE drops, tax credits, and policy, lowering US electricity costs.

✅ Utility-scale solar is about one-third cheaper than gas

✅ Onshore wind costs roughly 44 percent less than natural gas

✅ Policy and tax credits accelerate renewables and cut power prices

Natural gas’s dominance as power-plant fuel in the US is fading fast as the cost of electricity generated by US wind and solar projects tumbles and as wind and solar surpass coal in the generation mix, according to Guggenheim Securities.

Utility-scale solar is now about a third cheaper than gas-fired power, while onshore wind is about 44% less expensive, Guggenheim analysts led by Shahriar Pourreza said Monday in a note to clients, a dynamic consistent with falling wholesale power prices in several markets today. 

“Solar and wind now present a deflationary opportunity for electric supply costs,” the analysts said, which “supports the case for economic deployment of renewables across the US,” as the country moves toward 30% wind and solar and one-fourth of total generation in the near term.

Gas prices have surged amid a global supply crunch after Russia’s invasion of Ukraine, while tax-credit extensions and sweeping US climate legislation have brought down the cost of wind and solar, even as renewables surpassed coal in 2022 nationwide. Renewables-heavy utilities like NextEra Energy Inc. and Allete Inc. stand to benefit, and companies that can boost spending on wind and solar, as wind, solar and batteries dominate the 2023 pipeline, will also see faster growth, Guggenheim said.
