Shaping a new energy world with storage solutions

[H3] To fight climate change we need carbon neutral energy production and distribution.
[H3]
For that, renewables such as wind and solar are key. But their supply fluctuates – and still, energy demand has to be met, and the grid has to operate reliably and economically.
While today’s energy producers respond to grid fluctuations by mainly relying on fossil-fired power plants, energy storage solutions will take on a dominant role in fulfilling this need in the future, supplying renewable energy 24/7. It’s already taking shape today – and in the coming years it will become a more and more indispensable and flexible part of our new energy world.

Present

Future

Today, in a variety of cases, battery storage is being used as an efficient method of supplying power when needed. For example, many large offshore vessels or drilling platforms use it for their electricity needs. In power plants, together with mechanical flywheels, batteries are being used for ensuring grid stability, to perform ‘black starts’ (without external power sources) if needed, and support frequency regulation. They are also directly connected to the grid as stand-alone solutions to help with fluctuating power supply and demand. And combining renewables – such as wind farms – with battery storage can successfully manage power depending on current needs.

[IMG: icon]

[IMG: icon]

By mid-century, we envision a nearly completely decarbonized world with power produced from renewable sources only, resulting in efficient power consumption across society, intelligent management of a decentralized power grid, and the wide use of different energy storage technologies. Batteries will be used for short-term storage of electricity, and, for mid-term storage, combinations of thermal and mechanical storage solutions will provide industrial heat and electricity. Also, electrolyzers will turn excess power from renewables into green hydrogen that can be stored long term and turned into electricity or transferred to other sectors of the economy as needed.

Your challenges – our solutions

The situation energy producers, distributers and industrial consumers find themselves in is by no means easy. They face constant social pressure to decarbonize – and risk ruining their reputation if they appear not to act fast enough. As long as they emit CO2, they have to pay a hefty price for it. Once energy utilities close fossil-fired power plants, they have to manage stranded assets.
Also, renewable energy producers have to ensure a consistent availability of energy – and in order to do so, they may have to curtail output. And as the share of renewable energy increases year over year, operators are challenged to cost-efficiently match energy supply and demand and ensure grid stability.
But a steady flow of energy is non-negotiable: Industry, like many other sectors of the economy, relies on it in order to ensure its operations run smoothly and without interruption. The production of green hydrogen also requires renewable energy sources, but if none are available, energy still needs to be at hand to manufacture it.

Energy storage solves many of these problems:

[H3] No need to curtail energy

If you have a surplus in energy production, energy storage solutions can save it for later.

[H3] Take advantage of high energy prices

[H2] Get answers: FAQs on energy storage

[H3]
What is meant by energy storage?

Energy storage refers to the process of capturing energy produced at one time for use at a later time. This is particularly important for balancing supply and demand, ensuring a stable and reliable energy supply, and integrating renewable energy sources like solar and wind, which can be intermittent.

Energy storage works by converting energy from its original form into a storable form and then converting it back when needed.

[H3]
What types of energy storage technologies are commonly used?

Battery Storage: Batteries store electrical energy in chemical form. When energy is needed, the chemical energy is converted back into electrical energy. This is useful for short-term storage and applications like grid stability and frequency regulation.

Thermal Storage: This involves storing energy in the form of heat. For example, excess electricity can be used to heat a material (like molten salt), which can then be used to generate electricity later.

Mechanical Storage: This includes methods like pumped hydro storage, where water is pumped to a higher elevation using excess electricity and then released to generate electricity when needed. Flywheels are another example, where rotational energy is stored and then converted back to electricity.

Hydrogen Storage: Excess electricity can be used to produce hydrogen through electrolysis. The hydrogen can be stored and later used in fuel cells to generate electricity or for other applications.

[H3]
How do energy storage solutions contribute to a carbon-neutral energy future?

Energy storage solutions play a critical role in the transition to a carbon-neutral energy future by enabling the integration of renewable energy sources like wind and solar into the power grid. They store surplus energy generated during periods of high production and release it during periods of high demand or low renewable energy availability, ensuring grid stability and reliability. By reducing the reliance on fossil-fuel-based power generation, energy storage supports decarbonization and helps create a sustainable energy ecosystem.

Why electrical grid expansion and modernization can’t wait

Much of today's power grid infrastructure was built decades ago for a one-way electricity flow from centralized coal and nuclear plants to consumers. Today, grids must be far smarter and more flexible: they need to handle two-way electricity flows, integrate variable output from solar and wind farms, and connect millions of decentralized resources like rooftop solar panels or local biomass plants. Without urgent modernization and expansion, millions of megawatts of renewable projects remain stuck in connection queues, stalling the energy transition.
By 2040, more than 80 million kilometers of electrical grid will need to be added or upgraded globally—about the length of rebuilding the entire current grid. And right now, over 3,000 gigawatts of renewable projects are waiting for grid connections, signaling that grid investments lag far behind renewable installations. Currently, only about 60 cents is spent on grid and storage for every U.S. dollar invested in renewables, yet the International Energy Agency (IEA) states a 1:1 investment ratio is essential.
Grid modernization is no longer optional—it’s central to meeting climate goals.

[H2]
Key drivers for grid modernization and expansion

The urgent need for grid modernization and expansion is driven by the rapid growth of renewable energy, increasing electricity demand from electrification and digital infrastructure, and the risks posed by aging grid infrastructure that limits reliability and renewable integration.

[H3]
1. Renewables expansion

Global climate targets depend on scaling renewables fast, but new wind and solar projects must connect to grids strong enough to handle their variable supply across long distances. For example, the International Renewable Energy Agency (IRENA) calls for tripling renewable capacity by 2030, which current grids cannot support without major upgrades. Stronger, more flexible grids enable continuous renewable power delivery, vital to ongoing decarbonization.

[H3]
2. Increasing electricity demand

Electrification of industries, homes, and transportation – and the surge of digital infrastructure like data centers—are driving demand well beyond existing grid capacity. Data center electricity consumption alone could surpass 1,000 terawatt-hours globally by 2026, more than Japan’s current usage. Integration requires smarter networks, demand management, and digital grids to keep supply reliable and affordable while supporting growth.

[H3]
3. Aging infrastructure risks

Much of the global grid is past its design life: In Europe, nearly 40 percent of transmission lines are over 40 years old; in the U.S., many are 25 to 50 years old or more. Aging assets increase outage risks, maintenance costs, and bottlenecks that limit renewable integration and cause reliability concerns. Annual grid spending is rising but still trails renewable deployment, making accelerated upgrades critical to energy security and system resilience.

[H2]
Key strategies for grid modernization and expansion

Meeting tomorrow’s energy needs depends on robust infrastructure, sustainable technologies, and advanced digital solutions that can handle increasing complexity.
Taken together, these approaches point to four strategies that guide grid modernization worldwide:
Grid connection: Grid connectivity solutions empower reliable, efficient, and sustainable integration of energy systems into the power grid.Grid digitalization: Leveraging AI, automation, and intelligent control systems to manage complexity, balance energy flows, and improve grid visibility and responsiveness. Grid resilience: Strengthening and renewing aging infrastructure, including equipment that relies on F-gases, and using digital technology to reduce outages and cyber risks.Grid decarbonization: Supporting high shares of renewables and sustainable grid technologies.
It’s not only about building more lines, modernizing and expanding the power grid is also about building smarter. Demand management can reduce peak loads and the need for costly new infrastructure, as seen in large-scale demand-response programs in the U.S. and Europe. Digitalization and AI tools are helping grid operators forecast demand, predict outages, and extend asset life through digital twins. And new cross-border interconnections, such as the Viking Link between Denmark and the UK, enable countries to share renewable power and strengthen resilience.

[H2]
The technologies powering grid modernization and expansion

Advanced technologies are central to grid modernization and expansion. From flexible alternating current transmission systems (FACTS) that stabilize renewable power flows to AI-driven digital tools, high-voltage direct current (HVDC) interconnections, and energy storage, these solutions reduce strain on electrical grids and prepare them to handle rising demand and increasing renewable generation.

[H3]
Interconnections between regional grids

Linking regional grids makes electricity systems stronger, cheaper, and more efficient. High-voltage direct current (HVDC) interconnectors allow countries to share power across borders, helping each other balance supply and demand. They also make better use of renewable energy by moving green electricity from where it’s generated to where it’s needed most. A prime example is the Viking Link between Denmark and the UK. Stretching 765 kilometers with a capacity of 1,400 megawatts—which enables clean power to flow reliably and efficiently between the two nations. The link can send surplus wind power one way and, when conditions shift, reverse the flow to support the other side, stabilizing the grid and cutting costs on both sides.

[H3]
Multi-terminal hubs: the next HVDC innovation

Traditional HVDC links connect one point to another. The next frontier is multi-terminal hubs, direct current (DC) switching stations that connect multiple lines and sources. These hubs make it possible to integrate power from multiple offshore wind farms and distribute it efficiently across regions, while also protecting the grid from faults. Siemens Energy, together with all four major German transmission operators, is currently developing this next generation of HVDC hubs—marking a major step toward more flexible, robust, and affordable energy transmission.

[H4]
Modernizing complex power grids: Axia Energia, Brazil

Siemens Energy and Axia Energia (formerly known as Eletrobras Chesf) are transforming Brazil’s power grid—one of the country’s largest retrofit projects—boosting efficiency, reliability, and setting new standards for the future of energy. See how innovation and teamwork are powering millions and shaping a sustainable tomorrow.

FACTS: Shock absorbers for the grid

Every time the wind drops or clouds pass over a solar farm, the flow of electricity changes. Multiply that across thousands of renewable plants and the challenge is clear: today’s grids must absorb constant fluctuations while keeping power reliable. One of the most important tools here are flexible alternating current transmission systems (FACTS). Acting like shock absorbers for the grid, they smooth out sudden changes and give operators real-time control over how electricity moves. The result: more renewable energy can be delivered through the networks we already have, without sacrificing stability or efficiency.

[H3]
Utilizing AI and digital technologies

From predicting storms to preventing blackouts, AI and digital tools are reshaping how the modern grid works. By transforming raw data into instant, actionable insights, these technologies make power grids smarter, faster, and more resilient. They forecast demand and weather shifts, increase line capacity, balance supply in real time, and extend the life of existing infrastructure through digital twins—virtual models that detect wear early, guide smarter maintenance, and test scenarios without risking damage. Adoption is accelerating—AI use in the energy sector grew by more than 20 percent in 2024 alone—highlighting its crucial role.

[H4]
Rewiring the grid for renewables: TenneT, Germany

At the site of a retired coal plant, the world’s first E-STATCOM has been built: a breakthrough grid stabilizer powered by supercapacitors. It delivers instant “artificial inertia,” keeping the grid stable as coal and nuclear plants are phased out. This technology is a benchmark for resilient, future-ready power grids.

Making the grid itself green: sustainable upgrades that cut emissions

The grid can do more than enable clean energy—it can also become a driver of sustainability in its own right. That means cutting emissions from grid technologies themselves. One priority is eliminating fluorinated gases like sulphur hexafluoride (SF₆) from electrical switchgear, which is 24,300 times more harmful to the climate than CO₂. Through its Blue portfolio of switchgear, Siemens Energy replaces SF₆ with clean air and vacuum switching technology, reducing the carbon footprint of substations.
Another major opportunity lies in circularity. Using recycled materials not only reduces emissions but also strengthens supply chains for critical components. In September 2024, Siemens Energy and TenneT agreed to supply transformers with 100-percent recycled copper windings. If recycled copper were used for all new transformers worldwide to expand the electrical grid by 2040, the savings could reach 14 million metric tons of greenhouse gas emissions. Changes like these show how upgrading grids can advance both climate goals and resource security.

[H3]
Expanding energy storage systems

Without storage, much renewable energy would be wasted. Batteries provide rapid balancing for short-term demand spikes, while green hydrogen enables long-term storage by converting surplus renewable electricity into a clean fuel—one that can be fed back into the grid or used in other sectors. Siemens Energy is scaling both: Its grid-scale battery systems support real-time balancing, and its Gigawatt Factory in Berlin produces electrolyzers to expand green hydrogen production. As storage capacity grows, it will play a central role in creating reliable, 24/7 clean power systems.

[H4]
More strength for the North American grid: IPA, Utah, USA

Transforming a former coal plant into a renewable powerhouse with the largest synchronous condenser project in North America is a large undertaking. But the innovative setup of the Intermountain Power Project is key to providing reactive power and stabilizing the grid.

Investing in the future of energy

Meeting global climate and energy goals hinges on investing at least one dollar in grids and storage for every dollar in renewables. The most cost-effective pathway is timely, coordinated grid modernization combining advanced hardware, digital innovation, and sustainable practices. Strategic partnerships, long-term planning, and shared investments will enable a resilient, clean, and future-proof electricity system.

A twentieth-century grid cannot support a twenty-first-century economy. A modern grid ensures energy resilience, security, and independence for generations.

The question is how to invest wisely and act now. Delayed or piecemeal fixes will cost more and slow progress. The transition demands bold grid expansion today for a cleaner, more reliable tomorrow.

Local manufacturing: a critical success factor

Grid modernization requires massive transformer and equipment production—key components like transformers step down voltage for safe delivery. In the U.S., 90 percent of power flows through large transformers. The National Renewable Energy Laboratory (NREL) estimates that the number of large transformers may need to increase by as much as 260 percent by 2050 to meet rising demand and the build-out of renewable energy. Yet today, about 80 percent of U.S. transformers are imported, with delivery times stretching up to five years.
To close this gap, Siemens Energy is expanding its manufacturing and service operations of large power transformers in Charlotte, North Carolina – an investment creating nearly 600 direct jobs and 300 construction jobs. Similar expansions are underway across its Grid Technologies factories worldwide. The challenge is that key materials like copper, aluminum, and steel are still heavily imported, leaving costs vulnerable to tariffs and supply chain pressures. With government support to strengthen local supply chains, local manufacturing can accelerate grid modernization while boosting sustainability, resilience, and energy security.

The reliability and resilience of the U.S. electric grid are vital for both energy and national security. Large power transformers (LPTs) are critical components, but currently more than 80 percent are imported, with lead times of up to five years. In response to this challenge, Siemens Energy is expanding its manufacturing and service operations in Charlotte, North Carolina.
