Electric energy storage enables grid flexibility for renewables using utility-scale batteries and pumped-storage hydropower, delivering high round-trip efficiency, scalable capacity, and longer durations, according to EIA data as intermittent generation and demand variability increase.

 

Key Points

Electric energy storage saves power for later use using batteries and pumped storage to boost efficiency.

✅ Batteries: ~82% round-trip efficiency in 2019 (EIA)

✅ Pumped-storage: ~79% round-trip efficiency in 2019 (EIA)

✅ Pumped-storage 21.9 GW; utility-scale batteries 1.4 GW (Nov 2020)

 

Electric energy storage is becoming more important to the energy industry as the share of intermittent generating technologies, such as wind and solar, in the electricity mix increases. Electric energy storage helps to meet fluctuating demand, as many utilities see benefits from deployment, which is why it is often paired with intermittent sources. Storage technologies include batteries and pumped-storage hydropower, which capture energy and store it for later use and increasingly support EV-related grid flexibility as mobile chargers bring new options. Storage metrics can help us understand the value of the technology. Round-trip efficiency is the percentage of electricity put into storage that is later retrieved. The higher the round-trip efficiency, the less energy is lost in the storage process. According to data from the U.S. Energy Information Administration (EIA), in 2019, the U.S. utility-scale battery fleet operated with an average monthly round-trip efficiency of 82%, and pumped-storage facilities operated with an average monthly round-trip efficiency of 79%.


 

EIA’s Power Plant Operations Report provides data on utility-scale energy storage, and initiatives to enable storage in Ontario illustrate system-level integration, including the monthly electricity consumption and gross electric generation of energy storage assets, which can be used to calculate round-trip efficiency. The metrics reviewed here use the finalized data from the Power Plant Operations Report for 2019—the most recent year for which a full set of storage data is available.

Pumped-storage facilities are the largest energy storage resource in the United States, and regions anticipating tight supply, such as Ontario supply crunch, are also evaluating expanded storage portfolios. The facilities collectively account for 21.9 gigawatts (GW) of capacity and for 92% of the country’s total energy storage capacity as of November 2020.

In recent years, utility-scale battery capacity has grown rapidly as battery costs have decreased, and New York BESS is cited as a needed clean energy solution, underscoring this trend. As batteries have been increasingly paired with renewables in markets worldwide, including Ontario to rely on battery storage to meet rising demand, they have become the second-largest source of electricity storage. As of November 20, 2020, utility-scale battery capacity had 1.4 GW of operational capacity. Another 4.0 GW of battery capacity is scheduled to come online in 2021, according to EIA’s Preliminary Electric Generator Inventory.

Although battery storage has slightly higher round-trip efficiency than pumped storage, pumped-storage facilities typically operate at utilization factors that are currently twice as high as batteries. Increasing durations among battery applications could shift battery operations toward services that reward longer output periods. For example, in 2015, the weighted average battery duration was a little more than 46 minutes, but by 2019, weighted average battery durations had doubled to 1.5 hours, and emerging long-duration projects are targeting 100-hour capabilities. The role of batteries and their capability to provide high levels of round-trip efficiency may become more important as batteries continue to be deployed and as the intermittent renewables share of the electricity mix grows.

Will EV Supply Miss the Demand Mark in the Short and Medium Term?

EV Carpocalypse signals potential mismatch between electric vehicle production and demand, as charging infrastructure, utility coordination, and plug-in hybrid strategies lag forecasts, while state mandates and market-share plays drive cautious, data-informed scaling.

 

Key Points

EV Carpocalypse describes overbuilt EV supply versus demand amid charging rollout, mandates, and risk-managed scaling.

✅ Forecasts vs actual EV demand may diverge in near term

✅ Charging infrastructure and utilities lag vehicle output

✅ Mandates and PHEVs cushion adoption while data guides scaling

 

According to Forbes contributor David Kiley, and Wards Automotive columnist John McElroy, there may be an impending “carpocalypse” of electric vehicles on the way. Sounds very damning and it’s certainly not the upbeat tone I’ve taken on nearly every piece of EV demand content I’ve authored but the author, Kiley does bring up some interesting points worth considering. EV Adoption is happening, and it’s certainly doing so at ever faster rates as the market nears an EV inflection point today. The infrastructure (charging stations, utility cooperation) is being built out more slowly than vehicle manufacturers are producing cars but, as the GM president on EV hurdles has noted, the issue seems to be just that, maybe even the short and medium term plans for EV manufacturing are too aggressive.

#google#

With new EV and plug-in hybrid vehicle sales representing a mere .6% of new car cales in the US, a sign that EV sales remain behind gas cars even as new models proliferate, car makers are are going to be spending more than $100 billion to come out with more than a hundred models of battery electric vheicles which also includes PHEVs and the fear is these vehicles aren’t going to sell in the numbers that automakers and industry analysts may have expected. But forecasts are just that, forecasts, even as U.S. EV sales surge into 2024 suggest momentum. So there’s a valid argument to be made that they’ll either overshoot the true mark or come in way below the actual amount. With nine U.S. states mandating that 15% of new cars sold be EVs by 2025, you could say that at least automakers have supporters in state government helping to push the new technology into the hands of more drivers.

Still, it’s anyone’s guess as to what true adoption will be, and a brief Q1 2024 market share dip underscores lingering volatility. The use of big data and just in time manufacturing will ensure that manufacturers will miss the mark on EVs by less than they have in the past, and will able to cope with breaking even on these vehicles for the sake of gobbling up precious early stage market share. After all, many vendors have up to this point been very willing to break even or make a loss on their lease-only EVs or on EV or hybrid financing in order to gain that share and build out their brand awareness and technical prowess. With some stops and starts, demand will meet supply or supply may need to meet demand but either way, the EV adoption wave is coming to a driveway near you.

Tesla prepares to bring its electric cars to South America

Tesla Chile Market Entry signals EV expansion into South America, with a Santiago country manager, service technicians, and advisors, leveraging lithium supply, competing with BYD, and preparing sales, service, and charging infrastructure.

 

Key Points

Tesla will enter Chile to launch EV sales, service, and charging from Santiago, opening its South America expansion.

✅ Country manager role based in Santiago to lead market launch

✅ Focus on EV sales, service centers, and charging infrastructure

✅ Leverages Chile's lithium ecosystem; competes with BYD

 

Tesla is preparing to bring its electric cars to South America, according to a new job posting in Chile.

It has been just over a decade since Tesla launched the Model S and significantly accelerated EV inflection point in the deployment of electric vehicles around the world.

The automaker has expanded its efforts across North America, where the U.S. EV tipping point has been reached, and most countries in Europe, and it is still gradually expanding in Asia.

But there’s one continent that Tesla hasn’t touched yet: South America, even as global EV adoption raced to two million in five years.

It sounds like it is about to change.

Tesla has started to promote a job posting on LinkedIn for a country manager in Chile, aligning with international moves like UK expansion plans it has signaled.

The country manager is generally the first person hired when Tesla expands in a new market.

The job is going to be based in Santiago, the capital of Chile, where the company is also looking for some Tesla advisors and service technicians.

Chile is an interesting choice for a first entry into the South American market. The Chilean auto market consists of only about 234,000 vehicles sold year-to-date and that’s down 29% versus the previous year.

That’s roughly the number of vehicles sold in Brazil every month.

While the size of the auto market in the country is small, there’s a strong interest for electric vehicles as the EV era arrives ahead of schedule there, which might explain Tesla’s foray.

The country is rich in lithium, a critical material for EV batteries, where lithium supply concerns have also emerged, which has helped create interest for electric vehicles in the country. The government also announced an initiative to allow for only new sales of electric vehicles in the country starting in 2035.

Tesla’s Chinese competitor BYD has set its sight on the South American market by bringing its cheaper China-made EVs to the market, part of a broader Chinese EV push in Europe as well, but now it looks like Tesla is willing to test the market on the higher-end.

Intersolar Europe restart 2021: solar power is becoming increasingly popular in Poland

Poland Solar PV Boom drives record installations, rooftop and utility-scale growth, EU-aligned incentives, net metering, PPAs, and auctions, pushing capacity toward 8.3 GW by 2024 while prosumers, grid upgrades, and energy management expand.

 

Key Points

A rapid expansion of Poland's PV market, driven by incentives, PPAs, and prosumers across rooftop and utility-scale.

✅ 2.2 GW added in 2020, triple 2019, led by small-scale prosumers

✅ Incentives: My Current, Clean Air, Agroenergia, net metering

✅ Growth toward 8.3 GW by 2024; PPAs and auctions scale utility

 

Photovoltaics (PV) is booming in Poland. According to SolarPower Europe, 2.2 gigawatts (GW) of solar power was installed in the country in 2020 - nearly three times as much as the 823 megawatts (MW) installed in 2019. This places Poland fourth across Europe, behind Germany, where a solar power boost has been underway (4.8 GW added in 2020), the Netherlands (2.8 GW) and Spain (2.6 GW). So all eyes in the industry are on the up-and-coming Polish market. The solar industry will come together at Intersolar Europe Restart 2021, taking place from October 6 to 8 at Messe München. As part of The smarter E Europe Restart 2021, manufacturers, suppliers, distributors and service providers will all present their products and innovations at the world's leading exhibition for the solar industry.

All signs point to continued strong growth, with renewables on course to set records across markets. An intermediate, more conservative EU Market Outlook forecast from SolarPower Europe expects the Polish solar market to grow by 35 percent annually, meaning that it will have achieved a PV capacity of 8.3 GW by 2024 as solar reshapes Northern Europe's power prices over the medium term. "PV in Poland is booming at every level - from private and commercial PV rooftop systems to large free-standing installations," says Dr. Stanislaw Pietruszko, President of the Polish Society for Photovoltaics (PV Poland). According to the PV Poland, the number of registered small-scale systems - those under 50 kilowatts (kW) - with an average capacity of 6.5 kilowatts (kW) grew from 155,000 (992 MW) at the end of 2019 to 457,400 (3 GW) by the end of 2020. These small-scale systems account for 75 percent of all PV capacity installed in Poland. Larger PV projects with a capacity of 4 GW have already been approved for grid connection, further attesting to the forecast growth.

8,000 people employed in the PV industry
Andrzej Kazmierski, Deputy Director of the Department for Low-emission Economy within the Polish Ministry of Economic Development, Labour and Technology, explained in the Intersolar Europe webinar "A Rising Star: PV Market Poland" at the end of March 2021 that the PV market volume in Poland currently amounts to 2.2 billion euros, with 8,000 people employed in the industry. According to Kazmierski, the implementation of the Renewable Energy Directive (RED II) in the EU, intended to promote energy communities and collective prosumers as well as long-term power purchase agreements (PPAs), will be a critical challenge, and ongoing Berlin PV barriers debates highlight the importance of regulatory coordination. Renewable energy must be integrated with greater focus into the energy system, and energy management and the grids themselves must be significantly expanded as researchers work to improve solar and wind integration. The government seeks to create a framework for stable market growth as well as to strengthen local value creation.


Government incentive programs in Poland
In addition to drastically reduced PV costs, reinforced by China's rapid PV expansion, and growing environmental consciousness, the Polish PV market is being advanced by an array of government-funded incentive programs such as My Current (230 million euros) and Clean Air as well as thermo-modernization. The incentive program Agroenergia (50 million euros) is specifically geared toward farmers and offers low-interest loans or direct subsidies for the construction of solar installations with capacities between 50 kW and 1 MW. Incentive programs for net metering have been extended to small and medium enterprises to provide stronger support for prosumers. Solar installations producing less than 50 kW benefit from a lower value-added tax of just eight percent (compared to the typical 23 percent). The acquisition and installation costs can be offset against income, in turn reducing income tax.
Government-funded auctions are also used to finance large-scale facilities, where the government selects operators of systems running on renewable energy who offer the lowest electricity price and funds the construction of their facilities. The winner of an auction back in December was an investment project for the construction of a 200 MW solar park in the Pomeranian Voivodeship.


Companies turn to solar power for self-consumption
Furthermore, Poland is now playing host to larger solar projects that do not rely on subsidies, as Europe's demand lifts US equipment makers amid supply shifts, such as a 64 MW solar farm in Witnica being built on the border to Germany whose electricity will be sold to a cement factory via a multi-year power purchase agreement. A new factory in Konin (Wielkopolska Voivodeship) for battery cathode materials to be used in electric cars will be powered with 100-percent renewable electricity. Plus, large companies are increasingly turning to solar power for self-consumption. For example, a leading manufacturer of metal furniture in Suwalki (Podlaskie Voivodeship) in northeastern Poland has recently started meeting its demand using a 2 MW roof-mounted and free-standing installation on the company premises.

Why Electric Vehicles Are "Greener" Than Ever In All 50 States

UCS EV emissions study shows electric vehicles produce lower life-cycle emissions than gasoline cars across all states, factoring tailpipe, grid mix, power plant sources, and renewable energy, delivering mpg-equivalent advantages nationwide.

 

Key Points

UCS study comparing EV and gas life-cycle emissions, finding EVs cleaner than new gas cars in every U.S. region.

✅ Average EV equals 93 mpg gas car on emissions.

✅ Cleaner than 50 mpg gas cars in 97% of U.S.

✅ Regional grid mix included: tailpipe to power plant.

 

One of the cautions cited by electric vehicle (EV) naysayers is that they merely shift emissions from the tailpipe to the local grid’s power source, implicating state power grids as a whole, and some charging efficiency claims get the math wrong, too. And while there is a kernel of truth to this notion—they’re indeed more benign to the environment in states where renewable energy resources are prevalent—the average EV is cleaner to run than the average new gasoline vehicle in all 50 states. 

That’s according to a just-released study conducted the Union of Concerned Scientists (UCS), which determined that global warming emissions related to EVs has fallen by 15 percent since 2018. For 97 percent of the U.S., driving an electric car is equivalent or better for the planet than a gasoline-powered model that gets 50 mpg. 

In fact, the organization says the average EV currently on the market is now on a par, environmentally, with an internal combustion vehicle that’s rated at 93 mpg. The most efficient gas-driven model sold in the U.S. gets 59 mpg, and EV sales still trail gas cars despite such comparisons, with the average new petrol-powered car at 31 mpg.

For a gasoline car, the UCS considers a vehicle’s tailpipe emissions, as well as the effects of pumping crude oil from the ground, transporting it to a refinery, creating gasoline, and transporting it to filling stations. For electric vehicles, the UCS’ environmental estimates include both emissions from the power plants themselves, along with those created by the production of coal, natural gas or other fossil fuels used to generate electricity, and they are often mischaracterized by claims about battery manufacturing emissions that don’t hold up. 

Of course the degree to which an EV ultimately affects the atmosphere still varies from one part of the country to another, depending on the local power source. In some parts of the country, driving the average new gasoline car will produce four to eight times the emissions of the average EV, a fact worth noting for those wondering if it’s the time to buy an electric car today. The UCS says the average EV driven in upstate New York produces total emissions that would be equivalent to a gasoline car that gets an impossible 255-mpg. In even the dirtiest areas for generating electricity, EVs are responsible for as much emissions as a conventionally powered car that gets over 40 mpg.

Building Energy Celebrates the Beginning of Operations and Electricity Generation

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.

Shanghai Electric Signs Agreement to Launch PEM Hydrogen Production Technology R&D Center, Empowering Green Hydrogen Development in China

Shanghai Electric PEM Hydrogen R&D Center advances green hydrogen via PEM electrolysis, modular megawatt electrolyzers, zero carbon production, and full-chain industrial applications, accelerating decarbonization, clean energy integration, and hydrogen economy scale-up across China.

 

Key Points

A joint R&D hub advancing PEM electrolysis, modular megawatt systems, and green hydrogen industrialization.

✅ Megawatt modular PEM electrolyzer design and system integration

✅ Zero-carbon hydrogen targeting mobility, chemicals, and power

✅ Full-chain collaboration from R&D to EPC and demonstration projects

 

Shanghai Electric has reached an agreement with the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences (the "Dalian Institute") to inaugurate the Proton Exchange Membrane (PEM) Hydrogen Production Technology R&D Center on March 4. The two parties signed a project cooperation agreement on Megawatt Modular and High-Efficiency PEM Hydrogen Production Equipment and System Development, marking an important step forward for Shanghai Electric in the field of hydrogen energy.

As one of China's largest energy equipment manufacturers, Shanghai Electric is at the forefront in the development of green hydrogen as part of China's clean energy drive. During this year's Two Sessions, the 14th Five-Year Plan was actively discussed, in which green hydrogen features prominently, and Shell's 2060 electricity forecast underscores the scale of electrification. With strong government support and widespread industry interest, 2021 is emerging as Year Zero for the hydrogen energy industry.

Currently, Shanghai Electric and the Dalian Institute have reached a preliminary agreement on the industrial development path for new energy power generation and electrolyzed water hydrogen production. As part of the cooperation, both will also continue to enhance the transformational potential of PEM electrolyzed water hydrogen production, accelerate the development of competitive PEM electrolyzed hydrogen products, and promote industrial applications and scenarios, drawing on projects like Japan's large H2 energy system to inform deployment. Moreover, they will continue to carry out in-depth cooperation across the entire hydrogen energy industry chain to accelerate overall industrialization.

Hydrogen energy boasts the biggest potential of all the current forms of clean energy, and the key to its development lies in its production. At present, hydrogen production primarily stems from fossil fuels, industrial by-product hydrogen recovery and purification, and production by water electrolysis. These processes result in significant carbon emissions. The rapid development of PEM water electrolysis equipment worldwide in recent years has enabled current technologies to achieve zero carbon emissions, effectively realizing green, clean hydrogen. This breakthrough will be instrumental in helping China achieve its carbon peak and carbon-neutrality goals.

The market potential for hydrogen production from electrolyzed water is therefore massive. Forecasts indicate that, by 2050, hydrogen energy will account for approximately 10% of China's energy market, with demand reaching 60 million tons and annual output value exceeding RMB 10 trillion. The Hydrogen: Tracking Energy Integration report released by the International Energy Agency in June 2020 notes that the number of global electrolysis hydrogen production projects and installed capacity have both increased significantly, with output skyrocketing from 1 MW in 2010 to more than 25 MW in 2019. Much of the excitement comes from hydrogen's potential to join the ranks of natural gas as an energy resource that plays a pivotal role in international trade, as seen in Germany's call for hydrogen-ready power plants shaping future power systems, with the possibility of even replacing it one day. In PwC's 2020 The Dawn of Green Hydrogen report, the advisory predicts that experimental hydrogen will reach 530 million tons by mid-century.

Shanghai Electric set its focus on hydrogen energy years ago, given its major potential for growth as one of the new energy technologies of the future and, in particular, its ability to power new energy vehicles. In 2016, the Central Research Institute of Shanghai Electric began to invest in R&D for key fuel cell systems and stack technologies. In 2020, Shanghai Electric's independently-developed fuel cell engine, which boasts a power capacity of 66 kW and can start in cold temperature environments of as low as -30°C, passed the inspection test of the National Motor Vehicle Product Quality Inspection Center. It adopts Shanghai Electric's proprietary hydrogen circulation system, which delivers strong power and impressive endurance, with the potential to replace gasoline and diesel engines in commercial vehicles.

As the technology matures, hydrogen has entered a stage of accelerated industrialization, with international moves such as Egypt's hydrogen MoU with Eni signaling broader momentum. Shanghai Electric is leveraging the opportunities to propel its development and the green energy transformation. As part of these efforts, Shanghai Electric established a Hydrogen Energy Division in 2020 to further accelerate the development and bring about a new era of green, clean energy.

As one of the largest energy equipment manufacturing companies in China, Shanghai Electric, with its capability for project development, marketing, investment and financing and engineering, procurement and construction (EPC), continues to accelerate the development and innovation of new energy. The Company has a synergistic foundation and resource advantages across the industrial chain from upstream power generation, including China's nuclear energy development efforts, to downstream chemical metallurgy. The combined elements will accelerate the pace of Shanghai Electric's entry into the field of hydrogen production.

Currently, Shanghai Electric has deployed a number of leading green hydrogen integrated energy industry demonstration projects in Ningdong Base, one of China's four modern coal chemical industry demonstration zones. Among them, the Ningdong Energy Base "source-grid-load-storage-hydrogen" project integrates renewable energy generation, energy storage, hydrogen production from electrolysis, and the entire industrial chain of green chemical/metallurgy, where applications like green steel production in Germany illustrate heavy-industry decarbonization.

In December 2020, Shanghai Electric inked a cooperation agreement to develop a "source-grid-load-storage-hydrogen" energy project in Otog Front Banner, Inner Mongolia. Equipped with large-scale electrochemical energy storage and technologies such as compressed air energy storage options, the project will build a massive new energy power generation base and help the region to achieve efficient cold, heat, electricity, steam and hydrogen energy supply.
