Texas battery rush: Oil state's power woes fuel energy storage boom

Faroe Islands Tidal Kites harness predictable ocean energy with underwater turbines by Minesto, flying figure-eight paths in fjords to amplify tidal power and deliver renewable electricity to SEV's grid near Vestmanna at megawatt scale.

Key Points

Subsea turbines that fly figure-eight paths to harvest tidal currents, delivering reliable renewable power to the grid.

✅ Figure-eight control amplifies speed vs. ambient current

✅ Predictable baseload complementing wind and hydro

✅ 1.2 MW Dragon-class units planned for Faroese fjords

Known as "sea dragons" or "tidal kites", they look like aircraft, but these are in fact high-tech tidal turbines, part of broader ocean and river power efforts generating electricity from the power of the ocean.

The two kites - with a five-metre (16ft) wingspan - move underwater in a figure-of-eight pattern, absorbing energy from the running tide. They are tethered to the fjord seabed by 40-metre metal cables.

Their movement is generated by the lift exerted by the water flow - just as a plane flies by the force of air flowing over its wings.

Other forms of tidal power use technology similar to terrestrial wind turbines, and emerging kite-based wind power shows the concept's versatility, but the kites are something different.

The moving "flight path" allows the kite to sweep a larger area at a speed several times greater than that of the underwater current. This, in turn, enables the machines to amplify the amount of energy generated by the water alone.

An on-board computer steers the kite into the prevailing current, then idles it at slack tide, maintaining a constant depth in the water column. If there were several kites working at once, the machines would be spaced far enough apart to avoid collisions.

The electricity is sent via the tethering cables to others on the seabed, and then to an onshore control station near the coastal town of Vestmanna.

The technology has been developed by Swedish engineering firm Minesto, founded back in 2007 as a spin-off from the country's plane manufacturer, Saab.

The two kites in the Faroe Islands have been contributing energy to Faroe's electricity company SEV, and the islands' national grid, on an experimental basis over the past year.

Each kite can produce enough electricity to power approximately 50 to 70 homes.

But according to Minesto chief executive, Martin Edlund, larger-scale beasts will enter the fjord in 2022.

"The new kites will have a 12-metre wingspan, and can each generate 1.2 megawatts of power [a megawatt is 1,000 kilowatts]," he says. "We believe an array of these Dragon-class kites will produce enough electricity to power half of the households in the Faroes."

The 17 inhabited Faroe islands are an autonomous territory of Denmark. Located halfway between Shetland and Iceland, in a region where U.K. wind lessons resonate, they are home to just over 50,000 people.

Known for their high winds, persistent rainfall and rough seas, the islands have never been an easy place to live. Fishing is the primary industry, accounting for more than 90% of all exports.

The hope for the underwater kites is that they will help the Faroe Islands achieve its target of net-zero emission energy generation by 2030, with advances in wave energy complementing tidal resources along the way.

While hydro-electric power currently contributes around 40% of the islands' energy needs, wind power contributes around 12% and fossil fuels - in the form of diesel imported by sea - still account for almost half.

Mr Edlund says that the kites will be a particularly useful back-up when the weather is calm. "We had an unusual summer in 2021 in Faroes, with about two months with virtually no wind," he says.

"In an island location there is no possibility of bringing in power connections from another country, and tidal energy for remote communities can help, when supplies run low. The tidal motion is almost perpetual, and we see it as a crucial addition to the net zero goals of the next decade."

Minesto has also been testing its kites in Northern Ireland and Wales, where offshore wind in the UK is powering rapid growth, and it plans to install a farm off the coast of Anglesey, plus projects in Taiwan and Florida.

The Faroe Islands' drive towards more environmental sustainability extends to its wider business community, with surging offshore wind investment providing global momentum. The locals have formed a new umbrella organisation - Burðardygt Vinnulív (Faroese Business Sustainability Initiative).

It currently has 12 high-profile members - key players in local business sectors such as hotels, energy, salmon farming, banking and shipping.

The initiative's chief executive - Ana Holden-Peters - believes the strong tradition of working collaboratively in the islands has spurred on the process. "These businesses have committed to sustainability goals which will be independently assessed," she says.

"Our members are asking how they can make a positive contribution to the national effort. When people here take on a new idea, the small scale of our society means it can progress very rapidly."

One of the islands' main salmon exporters - Hiddenfjord - is also doing its bit, by ceasing the air freighting of its fresh fish. Thought to be a global first for the Atlantic salmon industry, it is now exporting solely via sea cargo instead.

According to the firm's managing director Atli Gregersen this will reduce its transportation CO2 emissions by more than 90%. However it is a bold move commercially as it means that its salmon now takes much longer to get to key markets.

For example, using air freight, it could get its salmon to New York City within two days, but it now takes more than a week by sea.

What has made this possible is better chilling technology that keeps the fresh fish constantly very cold, but without the damaging impact of deep freezing it. So the fish is kept at -3C, rather than the -18C or below of typical commercial frozen food transportation.

"It's taken years to perfect a system that maintains premium quality salmon transported for sea freight rather than plane," says Mr Gregersen. "And that includes stress-free harvesting, as well as an unbroken cold-chain that is closely monitored for longer shelf life.

"We hope, having shown it can be done, that other producers will follow our lead - and accept the idea that salmon were never meant to fly."

Back in the Faroe Island's fjords, a firm called Ocean Rainforest is farming seaweed.

The crop is already used for human food, added to cosmetics, and vitamin supplements, but the firm's managing director Olavur Gregersen is especially keen on the potential of fermented seaweed being used as an additive to cattle feed.

He points to research which appears to show that if cows are given seaweed to eat it reduces the amount of methane gas that they exhale.

"A single cow will burp between 200 and 500 litres of methane every day, as it digests," says Mr Gregersen. "For a dairy cow that's three tonnes per animal per year.

"But we have scientific evidence to show that the antioxidants and tannins in seaweed can significantly reduce the development of methane in the animal's stomach. A seaweed farm covering just 10% of the largest planned North Sea wind farm could reduce the methane emissions from Danish dairy cattle by 50%."

The technology that Ocean Rainforest uses to farm its four different species of seaweed is relatively simple. Tiny algal seedlings are affixed to a rope which dangles in the water, and they grow rapidly. The line is lifted using a winch and the seaweed strands simply cut off with a knife. The line goes back into the water, and the seaweed starts growing again.

Currently, Ocean Rainforest is harvesting around 200 tonnes of seaweed per annum in the Faroe Islands, but plans to scale this up to 8,000 tonnes by 2025. Production may also be expanded to other areas in Europe and North America.

Massachusetts released a much-awaited energy storage solicitation on Thursday offering up to $10 million for new projects.

Issued by the Massachusetts Clean Energy Center (MassCEC) and the Department of Energy Resources (DOER), the solicitation makes available $100,000 to $1.25 million in matching funds for each chosen project.

The solicitation springs from a state report issued last year that found Massachusetts could save electricity ratepayers $800 million by incorporating 600 MW of energy storage projects. The state plans to set a specific energy storage goal, now the subject of a separate proceeding before the DOER.

The state is offering money for projects that showcase examples of future storage deployment, help to grow the state’s energy storage economy, and contribute to the state’s clean energy innovation leadership.

MassCEC anticipates making about 10-15 awards. Applicants must supply at least 50 percent of total project cost.

The state is offering money for projects that showcase examples of future storage deployment, help to grow the state’s energy storage economy, and contribute to the state’s clean energy innovation leadership.

MassCEC anticipates making about 10-15 awards. Applicants must supply at least 50 percent of total project cost.

The state plans to allot about half of the money from the energy storage solicitation to projects that include utility partners. Both distribution scale and behind-the-meter projects, including net-zero buildings among others, will be considered, but must be grid connected.

The solicitation seeks innovative business models that showcase the commercial value of energy storage in light of the specific local energy challenges and opportunities in Massachusetts.

Projects also should demonstrate multiple benefits/value streams to ratepayers, the local utility, or wholesale market.

And finally, projects should help uncover market and regulatory issues as well as monetization and financing barriers.

The state anticipates teams forming to apply for the grants. Teams may include public and private entities and are are encouraged to include the local utility.

Proposals are due June 9. The state expects to notify winners September 8, with contracts issued within the following month. Projects must be installed within 18 months of receiving contracts.

California EV Adoption leads the U.S., with 37% of registered electric vehicles and 27% of charging locations, spanning Level 1, Level 2, and DC Fast stations, aligned with OCPI and boosted by CALeVIP funding.

Key Points

California EV adoption reflects the state's leading EV registrations and growth in private charging infrastructure.

✅ 37% of U.S. EVs, 27% of charging locations in 2022

✅ CALeVIP funding boosts public charging deployment

✅ OCPI-aligned data; EVs per charger rose to 75 in CA

California has consistently been at the forefront of electric vehicle (EV) adoption, with EV sales topping 20% in California underscoring this trend, and the proliferation of EV charging stations in the United States, maintaining this position since 2016. According to recent estimates from our State Energy Data System (SEDS), California accounts for 37% of registered light-duty EVs in the U.S. and 27% of EV charging locations as of the end of 2022.

The vehicle stock data encompass all registered on-road, light-duty vehicles and exclude any previous vehicle sales no longer in operation. The data on EV charging locations include both private and public access stations for Legacy, Level 1, Level 2, and DC Fast charging ports, excluding EV chargers in single-family residences. There is a data series break between 2020 and 2021, when the U.S. Department of Energy updated its data to align with the Open Charge Point Interface (OCPI) international standard, reflecting changes in the U.S. charging infrastructure landscape.

In 2022, the number of registered EVs in the United States, with U.S. EV sales soaring into 2024 nationwide, surged to six times its 2016 figure, growing from 511,600 to 3.1 million, while the number of U.S. charging locations nearly tripled, rising from 19,178 to 55,015. Over the same period, California saw its registered EVs more than quadruple, jumping from 247,400 to 1.1 million, and its charging locations tripled, increasing from 5,486 to 14,822.

California's share of U.S. EV registrations has slightly decreased in recent years as EV adoption has spread across the country, with Arizona EV ownership relatively high as well. In 2016, California accounted for approximately 48% of light-duty EVs in the United States, which was approximately 12 times more than the state with the second-highest number of EVs, Georgia. By 2022, California's share had decreased to around 37%, which was still approximately six times more than the state with the second-most EVs, Florida.

On the other hand, California's share of U.S. EV charging locations has risen slightly in recent years, as charging networks compete amid federal electrification efforts and partly due to the California Electric Vehicle Infrastructure Project (CALeVIP), which provides funding for the installation of publicly available EV charging stations. In 2016, approximately 25% of U.S. EV charging locations were in California, over four times as many as the state with the second-highest number, Texas. In 2022, California maintained its position with over four times as many EV charging locations as the state with the second-most, New York.

The growth in the number of registered EVs has outpaced the growth of EV charging locations in the United States, and in 2021 plug-in vehicles traveled 19 billion electric miles nationwide, underscoring utilization. In 2016, there were approximately 27 EVs per charging location on average in the country. Alaska had the highest ratio, with 67 EVs per charging location, followed by California with 52 vehicles per location.

In 2022, the average ratio was 55 EVs per charging location in the United States, raising questions about whether the grid can power an ongoing American EV boom ahead. New Jersey had the highest ratio, with 100 EVs per charging location, followed by California with 75 EVs per location.

U.S. Solar Panel Shipments 2021 surged to 28.8 million kW of PV modules, tracking utility-scale and small-scale capacity additions, driven by imports from Asia, resilient demand, supply chain constraints, and declining prices.

Key Points

Record 28.8M kW PV modules shipped in 2021; 80% imports; growth in utility- and small-scale capacity with lower prices.

✅ 28.8M kW shipped, up from 21.8M kW in 2020 (record capacity)

✅ 80% of PV module shipments were imports, mainly from Asia

✅ Utility-scale +13.2 GW; small-scale +5.4 GW; residential led

U.S. shipments of solar photovoltaic (PV) modules (solar panels) rose to a record electricity-generating capacity of 28.8 million peak kilowatts (kW) in 2021, from 21.8 million peak kW in 2020, based on data from our Annual Photovoltaic Module Shipments Report. Continued demand for U.S. solar capacity drove this increase in solar panel shipments in 2021, as solar's share of U.S. electricity continued to rise.

U.S. solar panel shipments include imports, exports, and domestically produced and shipped panels. In 2021, about 80% of U.S. solar panel module shipments were imports, primarily from Asia, even as a proposed tenfold increase in solar aims to reshape the U.S. electricity system.

U.S. solar panel shipments closely track domestic solar capacity additions; differences between the two usually result from the lag time between shipment and installation, and long-term projections for solar's generation share provide additional context. We categorize solar capacity additions as either utility-scale (facilities with one megawatt of capacity or more) or small-scale (largely residential solar installations).

The United States added 13.2 gigawatts (GW) of utility-scale solar capacity in 2021, an annual record and 25% more than the 10.6 GW added in 2020, according to our Annual Electric Generator Report. Additions of utility-scale solar capacity reached a record high, reflecting strong growth in solar and storage despite project delays, supply chain constraints, and volatile pricing.

Small-scale solar capacity installations in the United States increased by 5.4 GW in 2021, up 23% from 2020 (4.4 GW), as solar PV and wind power continued to grow amid favorable government plans. Most of the small-scale solar capacity added in 2021 was installed on homes. Residential installations totaled more than 3.9 GW in 2021, compared with 2.9 GW in 2020.

The cost of solar panels has declined significantly since 2010. The average value (a proxy for price) of panel shipments has decreased from $1.96 per peak kW in 2010 to $0.34 per peak kW in 2021, as solar became the third-largest renewable source and markets scaled. Despite supply chain constraints and higher material costs in 2021, the average value of solar panels decreased 11% from 2020.

In 2021, the top five destination states for U.S. solar panel shipments were:

California (5.09 million peak kW)
Texas (4.31 million peak kW)
Florida (1.80 million peak kW)
Georgia (1.15 million peak kW)
Illinois (1.12 million peak kW)
These five states accounted for 46% of all U.S. shipments, and 2023 utility-scale project pipelines point to continued growth.

EV Charging Infrastructure accelerates with federal funding, NEVI corridors, and Level 2/3 DC fast charging to cut range anxiety, support apartment dwellers, and scale to 500,000 public chargers alongside tax credits and state mandates.

Key Points

The network of public and private hardware, software, and policies enabling reliable Level 2/3 EV charging at scale.

✅ $7,500/$4,000 tax credits spur adoption and charger demand

✅ NEVI funding builds 500,000 public, reliable DC fast chargers

✅ Equity focus: apartment, curbside, bidirectional and inductive tech

Speaking in front of a line of the latest electric vehicles (EVs) at this month’s North American International Auto Show, President Joe Biden declared: “The great American road trip is going to be fully electrified.”

Most vehicles on the road are still gas guzzlers, but Washington is betting big on change, with EV charging networks competing to expand as it hopes that major federal investment will help reach a target set by the White House for 50% of new cars to be electric by 2030. But there are roadblocks – specifically when it comes to charging them all. “Range anxiety,” or how far one can travel before needing to charge, is still cited as a major deterrent for potential EV buyers.

The auto industry recently passed the 5% mark of EV market share – a watershed moment, arriving ahead of schedule according to analysts, before rapid growth. New policies at the state and local level could very well spur that growth: the Inflation Reduction Act, which passed this summer, offers tax credits of $4,000 to purchase a used EV and up to $7,500 for certain new ones. In August, California, the nation’s largest state and economy, announced rules that would ban all new gas-powered cars by 2035, as part of broader grid stability efforts in the state. New York plans to follow.

So now, the race is on to provide chargers to power all those new EVs.

The administration’s target of 500,000 public charging units by 2030 is a far cry from the current count of nearly 50,000, according to the Department of Energy’s estimate. And those new chargers will have to be fast – what’s known as Level 2 or 3 charging – and functional in order to create a truly reliable system, even as state power grids face added demands across regions. Today, many are not.

Last week, the White House approved plans for all 50 states, along with Washington DC, and Puerto Rico, to set up chargers along highways, unlocking $1.5bn in federal funding to that end, as US automakers’ charger buildout to complement public funds. The money comes from the landmark infrastructure bill passed last year, which invests $7.5bn for EV charging in total.

But how much of that money is spent is largely going to be determined at the local level, amid control over charging debates among stakeholders. “It’s a difference between policy and practice,” said Drew Lipsher, the chief development officer at Volta, an EV charging provider. “Now that the federal government has these policies, the question becomes, OK, how does this actually get implemented?” The practice, he said, is up to states and municipalities.

As EV demand spikes, a growing number of cities are adopting policies for EV charging construction. In July, the city of Columbus passed an “EV readiness” ordinance, which will require new parking structures to host charging stations proportionate to the number of total parking spots, with at least one that is ADA-accessible. Honolulu and Atlanta have passed similar measures.

One major challenge is creating a distribution model that can meet a diversity of needs.

At the moment, most EV owners charge their cars at home with a built-in unit, which governments can help subsidize. But for apartment dwellers or those living in multi-family homes, that’s less feasible. “When we’re thinking about the largest pieces of the population, that’s where we need to really be focusing our attention. This is a major equity issue,” said Alexia Melendez Martineau, the policy manager at Plug-In America, an EV consumer advocacy group.

Bringing power to people is one such solution. In Hoboken, New Jersey, Volta is working with the city to create a streetside charging network. “The network will be within a five-minute walk of every resident,” said Lipsher. “Hopefully this is a way for us to really import it to cities who believe public EV charging infrastructure on the street is important.” Similarly, in parts of Los Angeles – as in Berlin and London – drivers can get a charge from a street lamp.

And there may be new technologies that could help, exciting experts and EV enthusiasts alike. That could include the roads themselves charging EVs through a magnetizable concrete technology being piloted in Indiana and Detroit. And bidirectional charging, where, similar to solar panels, drivers can put their electricity back into the grid – or perhaps even to another EV, through what’s known as electric vehicle supply equipment (EVSE). Nissan approved the technology for their Leaf model this month.

Building Energy Iowa Wind Farm delivers 30 MW of renewable energy near Des Moines, generating 110 GWh annually with wind turbines, a long-term PPA, CO2 reduction, and community benefits like jobs and clean power.

Key Points

Building Energy Iowa Wind Farm is a 30 MW project generating 110 GWh a year, cutting CO2 and supporting local jobs.

✅ 30 MW capacity, 10 onshore turbines (3 MW each)

✅ ~110 GWh per year; power for 11,000 households

✅ Long-term PPA; jobs and emissions reductions in Iowa

With 110 GWh generated per year, the plant will be beneficial to Iowa's environment, reflecting broader Iowa wind power investment trends, contributing to the reduction of 100,000 tons of CO2 emissions, as well as providing economic benefits to host local communities.

Building Energy SpA, multinational company operating as a global integrated IPP in the Renewable Energy Industry, amid milestones such as Enel's 450 MW U.S. wind project, through its subsidiary Building Energy Wind Iowa LLC, announces the inauguration of its first wind farm in Iowa, which adds up to 30 MW of wind distribution generation capacity. The project, located north of Des Moines, in Story, Boone, Hardin and Poweshiek counties, will generate approximately 110 GWh per year. The beginning of operations has been celebrated on the occasion of the Wind of Life event in Ames, Iowa, in the presence of Andrea Braccialarghe, MD America of Building Energy, Alessandro Bragantini, Chief Operating Officer of Building Energy and Giuseppe Finocchiaro, Italian Consul General.

The overall investment in the construction of the Iowa distribution generation wind farms amounted to $58 million and it sells its energy and related renewable credits under a bundled, long-term power purchase agreement with a local utility, reflecting broader utility investment trends such as WEC Energy's Illinois wind stake in the region.

The wind facility, developed, financed, owned and operated by Building Energy, consists of ten 3.0 MW geared onshore wind turbines, each with a rotor diameter of 125 meters mounted on an 87.5 meter steel tower. The energy generated will satisfy the energy needs of 11,000 U.S. households every year, similar in community impact to North Carolina's first wind farm, while avoiding the emission of about 70,000 tons of CO2 emissions every year, according to US Environmental Protection Agency methodology, which is equivalent to taking 15,000 cars off the road each year.

Besides the environmental benefits, the wind farm also has advantages for the local community, providing it with clean energy and creating jobs for local Iowans. The project involved more than a hundred of local skilled workers during the construction phase. Some of those jobs will be also permanent as necessary for the operation and maintenance activities as well as for additional services such as delivery, transportation, spare parts management, landscape mitigation, and further environmental monitoring studies.

The Company is present in many US states since 2013 with more than 500 MW of projects under development, spread across different renewable energy technologies, and aligning with federal initiatives like DOE wind energy awards that support innovation.
