Introduction: The "Battery as Structure" Paradigm
The global push for electric mobility is accelerating, but it faces a significant roadblock: the immense weight of traditional lithium-ion batteries. These powerful energy sources add substantial mass to electric vehicles (EVs), which in turn limits their range and overall efficiency. A revolutionary technology poised to shatter this limitation is emerging: structural battery composites. By 2026, this innovation won't just improve EVs; it will fundamentally redefine how they are designed and built.
Defining Structural Battery Composites (SBCs)
At their core, structural battery composites are advanced, multifunctional materials that perform two jobs simultaneously: they store electrical energy like a conventional battery and bear mechanical loads as part of the vehicle's frame. This technology combines three distinct fields: materials science, electrochemistry, and structural engineering. Instead of designing a car and then finding a place to install a heavy battery pack, engineers can now build the car's chassis out of the battery itself. The key components enabling this fusion are structural electrodes (often made from carbon fiber), a solid polymer electrolyte that also acts as a bonding resin, and integrated reinforcement fibers.
The Core Concept: "Massless" Energy Storage
The central idea behind this technology is often called "massless" energy storage. This doesn't mean the battery has no weight; rather, its mass becomes part of the load-bearing structure, effectively vanishing as a separate, parasitic component. In this new paradigm, essential vehicle components like the floor pan, roof, or door panels serve a dual role as both the vehicle's skeleton and its power source. This approach eliminates the need for the heavy casings, modules, and protective structures that make up a traditional battery pack. It's a fundamental shift from the "battery-in-a-box" model to a fully integrated, energy-storing chassis.
The Promise for EVs in 2026
By integrating energy storage directly into the vehicle's structure, structural battery composites offer a trifecta of benefits expected to mature by 2026. These advantages create a virtuous cycle of improvement, addressing the core challenges of EV adoption.
- Lighter Vehicles: Removing the dedicated battery pack, which can weigh over 500 kg, could reduce a vehicle's total weight by up to 20%. This drastic weight reduction makes the vehicle more efficient.
- Longer Range: The efficiency gains from a lighter vehicle directly translate to longer range. Furthermore, by utilizing the entire chassis volume for energy storage, some projections suggest a potential range increase of up to 70%.
- Superior Design: Eliminating the bulky "skateboard" battery pack gives designers unprecedented freedom. This allows for truly flat floors, increased cabin space, and the creation of entirely new vehicle architectures that are impossible with today's designs.
Infographic: A Fundamental Shift in EV Architecture
The transition from traditional battery packs to structural composites represents a complete reimagining of the electric vehicle. It moves from an assembly of separate parts to a truly integrated system.
| Feature | Traditional EV Layout ("Battery-in-a-Box") | Structural Battery Composite (SBC) EV Layout |
|---|---|---|
| Energy Storage | Contained within a single, heavy, dedicated pack casing. | Distributed throughout the vehicle's chassis and body panels. |
| Structural Role | Battery pack is parasitic weight; the chassis provides all structural support. | The battery is the structure, providing stiffness and load-bearing capacity. |
| Weight | High. The pack and its housing add significant "dead weight" to the vehicle. | Low. Eliminates redundant structural mass, leading to a much lighter vehicle. |
| Design Impact | Constrained by the large, rectangular battery "skateboard," often creating a raised cabin floor. | Enables flat floors, greater interior volume, and novel vehicle shapes. |
How Structural Battery Composites Work
Unlike a traditional battery that is a distinct and separate component, a structural battery composite is a fully integrated, load-bearing part of the vehicle. Its ability to both power the car and support it mechanically comes from a sophisticated synergy of advanced materials, each chosen for its ability to perform at least two critical functions.
Core Materials and Their Dual Functions
The ingenuity of structural batteries lies in making every material work twice as hard. Traditional battery components are replaced by materials that combine electrochemical properties with mechanical strength.
Carbon Fiber as a Multifunctional Electrode
The primary building block is often carbon fiber, a material renowned for its high strength and low weight. In this application, it serves a triple purpose. First, it provides the primary structural stiffness and strength for the composite panel. Second, its inherent microstructure allows it to intercalate (store) lithium ions, enabling it to function as the negative electrode, or anode. Finally, its excellent electrical conductivity means it can also act as the current collector, eliminating the need for the separate copper foil found in conventional lithium-ion cells.
The Structural Solid-State Electrolyte
A key innovation is the development of a structural solid-state electrolyte. This material replaces the flammable liquid electrolyte used in most current EVs. It has two main jobs: first, as an electrolyte, it facilitates the transfer of ions between the anode and cathode. Second, it acts as the polymer matrix, or resin, that binds the carbon fibers together, transferring mechanical loads between them and giving the composite its rigid shape. This solid-state design is crucial for both safety and durability.
Cathode and Separator Integration
The positive electrode (cathode) is typically made from a conventional active material like Lithium Iron Phosphate (LFP), which is coated onto a conductive surface. In some designs, this surface is a thin metallic foil, while more advanced concepts apply the coating directly onto another layer of carbon fibers. To prevent short circuits, an insulating separator is placed between the anode and cathode. This is often a glass fiber fabric, which not only provides excellent electrical insulation but also contributes significantly to the overall structural integrity of the composite panel.
The Multilayer Composite Design
A structural battery panel is built like a high-tech sandwich, resembling the construction of traditional aerospace-grade carbon fiber components. Each layer performs a specific electrochemical function while contributing to the mechanical whole. A typical layup involves a precise stacking of these multifunctional materials:
- Carbon Fiber Layer (Anode): The structural and negative electrode foundation.
- Separator/Electrolyte Layer: A glass fiber fabric impregnated with the solid-state polymer electrolyte for insulation and ion transport.
- Cathode Layer: An active material (e.g., LFP) coated onto a current collector.
Multiple sets of these layers are stacked together and then cured under heat and pressure. This process solidifies the polymer electrolyte, fusing all the layers into a single, rigid, and electrochemically active panel. This method allows for the creation of complex shapes, enabling components like floor pans or roof structures to become the battery.

Each layer in a structural battery composite serves both an electrical and a mechanical purpose, from the carbon fiber anode to the integrated separator and cathode.
Comparison to Traditional Battery Packs
The architectural difference between a vehicle using structural battery composites and one with a conventional battery pack is profound. The traditional method involves assembling many small parts into a large, heavy, and passive component, while the SBC approach is about true system integration.
Traditional Architecture: The "Box"
The standard EV battery pack is an exercise in redundancy. Thousands of individual cells are first bundled into modules. These modules are then placed inside a large, heavy protective casing made of aluminum or steel, which is then bolted to the car's chassis. This pack requires dedicated, non-structural hardware for thermal management (like cooling plates), a separate Battery Management System (BMS), and extra structural members within the vehicle's frame just to support its immense weight.
SBC Architecture: The Integrated System
The SBC architecture eliminates nearly all of this redundant mass. There are no cells, modules, or heavy external pack casings; the energy storage system is the vehicle's chassis. By distributing the energy storage across a wide area, the need for concentrated, heavy cooling systems is greatly reduced. Furthermore, BMS sensors can be integrated directly into the structure, simplifying the electronics. This shift from aggregated components to an integrated system is the key to unlocking massive weight savings.
Component Breakdown: Traditional vs. Structural Battery Architecture
| Component | Traditional Battery Pack | Structural Battery Composite System |
|---|---|---|
| Energy Cells | Thousands of individual cylindrical or pouch cells. | No individual cells; energy stored in the material itself. |
| Modules | Cells grouped into multiple heavy modules. | Eliminated. |
| Pack Casing | Heavy, protective aluminum or steel enclosure. | Eliminated; the vehicle chassis is the "casing." |
| Support Structure | Additional chassis cross-members to support pack weight. | Eliminated; the battery provides structural support. |
| Thermal Management | Dedicated liquid cooling plates and pumps. | Simplified passive cooling due to large surface area. |
| Overall System | A heavy, isolated component added to the vehicle. | A lightweight, fully integrated vehicle system. |
Transforming EVs: Benefits in 2026
The widespread adoption of structural battery composites promises to catalyze the most significant leap in electric vehicle technology since the advent of the lithium-ion cell. By fundamentally changing the relationship between a vehicle's structure and its power source, these materials unlock a cascade of improvements in weight, range, performance, and safety that will define the next generation of EVs.
Weight Reduction
The most immediate and profound benefit of structural batteries is a dramatic reduction in vehicle weight. This is achieved through the principle of mass decompounding, a virtuous cycle where initial weight savings lead to even further reductions.
The Principle of Mass Decompounding
The process starts by eliminating the dedicated battery pack, a component that can weigh around 480 kg in a popular mid-size EV like the Tesla Model 3. This initial saving of up to 20% of the vehicle's total mass means that less powerful—and therefore lighter—motors, brakes, and suspension components are needed to achieve the same performance targets. This secondary weight saving further reduces the overall energy required for propulsion, creating a feedback loop of efficiency. Tesla's own move toward semi-structural packs in the Model Y is expected to reduce the vehicle's weight by 10%.
Extended Range and Efficiency
Reduced weight translates directly into superior range and efficiency, tackling the primary concern for many potential EV buyers. This is achieved through a two-pronged improvement in both direct efficiency and total energy capacity.
Direct Efficiency Gains
Lighter vehicles require less energy to accelerate and overcome rolling resistance. It's a fundamental principle of physics that pays significant dividends in an EV. Industry studies have shown a strong correlation: a 10% reduction in vehicle weight can improve energy efficiency by 6-8%. For an EV, this means more miles driven per kilowatt-hour, effectively stretching the energy stored in the battery.
Increased Energy Capacity
Beyond making the vehicle more efficient, structural battery composites allow for more energy to be stored in the first place. By turning large sections of the chassis into energy storage devices, SBCs utilize the vehicle's volume far more effectively than a traditional battery pack confined to a single box. Researchers at Chalmers University of Technology project that this dual approach of reducing weight and increasing storage volume could boost an EV's total range by as much as 70%.
Improved Design and Performance
The benefits of structural batteries extend beyond raw numbers, enabling a wholesale reimagining of vehicle dynamics and interior architecture.
Vehicle Dynamics and Handling
By distributing the battery mass across the vehicle's floor and integrating it into the structure, engineers can achieve a lower and more evenly distributed center of gravity. This inherently improves stability and handling. Furthermore, making the battery a core structural component significantly increases the chassis's torsional rigidity—its resistance to twisting forces. For example, BYD's "Cell-to-Body" technology creates a sandwich structure with a torsional rigidity of 40,500 N·m/°, a figure comparable to luxury performance cars. This stiffness provides a more stable platform for the suspension to work, resulting in better responsiveness, improved cornering, and reduced noise, vibration, and harshness (NVH).
Architectural Freedom
Perhaps most exciting for consumers is the newfound design freedom. The elimination of the "skateboard" battery pack allows for the first time a truly flat floor in an EV. This simple change unlocks vast potential for flexible interior layouts, increased cabin and storage volume, and more ergonomic seating positions. It opens the door to novel vehicle form factors that are simply not feasible with current battery architectures, such as ultra-lightweight sports cars or spacious, lounge-like autonomous shuttles.
Safety Enhancements
Integrating the battery into the car's structure while simultaneously moving to solid-state chemistry presents a major leap forward in EV safety.
Mitigating Thermal Runaway
Conventional EV batteries, with their thousands of cells packed tightly together and filled with flammable liquid electrolyte, carry the risk of thermal runaway—a chain reaction that can lead to fire. Structural batteries mitigate this in two ways. First, distributing energy storage over a larger area prevents a single point of failure from causing a catastrophic, pack-level event. Second, the solid-state electrolytes used in SBCs are inherently non-flammable and more thermally stable, removing the primary fuel source for a battery fire.
Improved Crashworthiness
Carbon fiber composites are known for their exceptional strength and ability to absorb and dissipate crash energy. Unlike metals that bend and deform, carbon fiber structures are designed to fracture in a controlled manner during a collision, absorbing impact forces and reducing their transmission to the passenger cabin. Studies comparing bumper beams have shown that on a per-mass basis, carbon fiber composites provide significantly higher energy absorption than steel or aluminum, making them an ideal material for enhancing occupant safety.
Safety Scenario Comparison: Concentrated vs. Distributed Energy
| Scenario | Traditional Pack (Concentrated Liquid Electrolyte) | Structural Composite (Distributed Solid Electrolyte) |
|---|---|---|
| Puncture/Impact | High risk of internal short circuit, leading to thermal runaway and fire due to flammable liquid electrolyte. | Localized damage. Non-flammable solid electrolyte prevents fire propagation. High-strength composite resists intrusion. |
| Severe Crash | Pack deformation can cause widespread cell failure. The heavy pack acts as a concentrated mass, complicating crash force management. | Integrated structure absorbs and dissipates energy through controlled fracture. Energy is distributed, not concentrated. |
| Overheating | A single cell overheating can trigger a chain reaction (thermal runaway) throughout the densely packed module. | Vastly improved thermal stability. Large surface area allows for better passive heat dissipation, reducing the chance of overheating. |
Key Developments and Players by 2026
The journey to make structural battery composites a commercial reality is being driven by a global ecosystem of university labs, agile startups, and automotive giants. By 2026, the fruits of this research and development will move from laboratory prototypes to tangible applications, led by key players who are pioneering this transformative technology.
Pioneering Research and Academia
The foundational breakthroughs in structural batteries are emerging from academic institutions that combine materials science and engineering. These universities are setting the performance benchmarks that industry will aim to commercialize.
Chalmers University of Technology (Sweden)
Chalmers University is arguably the global epicenter of structural battery research. For years, Professor Leif Asp and his team have been refining the core technology, focusing on using carbon fiber as the anode and developing robust solid-state electrolytes. Their work has produced a series of world-leading prototypes, demonstrating continuous improvement in the critical balance between mechanical strength and energy storage.
Chalmers University: Structural Battery Progress & Goals
| Metric | 2021 Performance | 2024 Performance | 2026 Target |
|---|---|---|---|
| Energy Density (Wh/kg) | 24 Wh/kg | 30 Wh/kg | 75 Wh/kg |
| Stiffness (Elastic Modulus) | 25 GPa | ~70-76 GPa | 75 GPa |
Chalmers has already achieved stiffness comparable to aluminum while steadily increasing energy density.
Other Key Institutions
Alongside Chalmers, other universities are making significant contributions. Imperial College London has been a key academic partner in European research projects on the topic, while Sweden's KTH Royal Institute of Technology has collaborated closely with Chalmers on developing these multifunctional materials.
Automotive Integration and Adoption
The automotive sector is the primary driver for structural battery commercialization. While true structural composites are still in advanced R&D, several automakers are already implementing intermediate concepts that validate the "battery-as-structure" paradigm.
Tesla's Structural Pack: A Stepping Stone
Tesla has been a trailblazer with its 4680 structural battery pack. While not a true composite material, it's a critical first step. In this design, the large cylindrical 4680 cells are not just held within a pack but are an integral part of its structure, bonded together to form a rigid unit. This pack eliminates the intermediate "module" level, connects the front and rear vehicle mega-castings, and serves as the floor of the car. This approach reduces parts, lowers weight, and significantly improves the vehicle's torsional rigidity. It serves as a powerful proof-of-concept for the immense benefits of integrating the battery into the chassis.
Legacy Automaker R&D (Projections for 2026)
Established automakers are accelerating their research. Volvo has been involved in structural power composites for over a decade, participating in EU-funded projects to develop energy-storing body panels, including trunk lids and plenum covers made from carbon fiber composites. By 2026, it is expected that major players like BMW, VW, and GM will be moving from pure research to demonstrating advanced semi-structural and fully-structural prototypes in their pre-production vehicle platforms.
Startups and Niche Applications
Hypercar manufacturers and specialized startups are often the first to adopt cutting-edge materials. Koenigsegg, known for its extensive use of carbon fiber chassis, is actively exploring integrated cell concepts in its advanced vehicle designs. Startups focused solely on structural battery composites are also emerging, targeting initial applications where the weight-to-performance ratio is paramount, such as in high-performance vehicles, drones, and aerospace.
Materials and Component Supply Chain
The viability of structural batteries depends on a robust supply chain for both advanced composites and battery materials. Major chemical and materials companies are positioned to be key enablers of this technology.
- Composite and Fiber Manufacturers: Industry leaders like Toray Industries, Hexcel Corporation, and SGL Carbon are central to producing the high-strength carbon fibers required for these applications.
- Battery Material and Cell Producers: Giants such as CATL, LG Chem, and Panasonic will play a crucial role. Their expertise in developing and scaling up the production of cathode materials and solid-state electrolytes will be essential for improving the energy density of structural composites.
Aerospace and Beyond
The advantages of massless energy storage are even more critical in aerospace, where every kilogram saved translates directly to increased payload or extended range.
- Airbus: The aerospace giant is actively experimenting with and developing concepts for energy-storing fuselage panels and wing skins, recognizing the transformative potential for future electric and hybrid-electric aircraft.
- UAVs and Drones: For Unmanned Aerial Vehicles (UAVs), structural batteries are a game-changer. Integrating the battery into the airframe is critical for extending flight times and mission capabilities, a key focus for both commercial and defense applications.
- Consumer Electronics: Looking further ahead, the technology promises thinner, lighter, and more durable consumer electronics. A laptop casing or smartphone back that also serves as the battery could revolutionize portable device design.
Challenges to Widespread Adoption
While the promise of structural battery composites is immense, significant hurdles in manufacturing, technology, and regulation must be overcome before they can be widely adopted in mass-market vehicles. These challenges require concurrent breakthroughs in material science, industrial engineering, and policy-making.
Manufacturing Complexities and Cost
The transition from traditional assembly lines to integrated composite manufacturing presents the most immediate barrier to adoption, primarily driven by high costs and complex processes.
High Material Costs
The foundational materials for high-performance structural batteries are inherently expensive. Aerospace-grade carbon fiber, prized for its strength-to-weight ratio, comes at a premium. While manufacturing fixed costs for composites can be lower than for steel, the raw material expense is a major obstacle. Some estimates show carbon fiber material prices can be upwards of $16 per pound, a stark contrast to automotive steel at around $0.40 per pound. Specialized solid-state polymer electrolytes add another layer of cost, making the bill of materials significantly higher than for a conventional EV.
Complex Production Processes
The manufacturing process for structural composites is intricate and time-consuming. It involves the careful co-curing of electrochemical and structural materials under precise temperature and pressure, a process that is far slower than the rapid cycle times of metal stamping and traditional battery pack assembly. Scaling this from laboratory batches to the high volumes required by the automotive industry will demand entirely new quality control methodologies and advanced automation to ensure every panel is both structurally sound and electrochemically flawless.
Technical Hurdles
Beyond manufacturing, fundamental technical challenges remain in balancing performance, ensuring long-term durability, and closing the significant gap in energy storage capacity compared to existing technologies.
The Performance Trilemma
Engineers face an inherent trade-off between three competing properties: mechanical strength, energy density, and power density. This "trilemma" means that improving one property often comes at the expense of another. For instance, adding more reinforcing fibers boosts stiffness but reduces the volume available for active battery materials, thereby lowering energy density. Conversely, maximizing energy storage might compromise the composite's ability to withstand mechanical stress. Finding the optimal balance for a given application is a central challenge of SBC development.
Chart: The Structural Battery Trilemma
Optimizing for one property, such as mechanical strength, often requires a compromise in another, like energy density, creating a constant balancing act for engineers.
Durability and Long-Term Performance
A structural battery must reliably perform thousands of charge and discharge cycles over a decade or more, all while being subjected to constant mechanical stress, vibration, and temperature fluctuations. Researchers are focused on ensuring these materials can resist fatigue and impact damage without degrading their electrochemical performance. Managing the different rates of thermal expansion and contraction between the various layers (carbon fiber, polymer, cathode materials) is another critical challenge to prevent delamination or internal damage over the vehicle's lifespan.
Energy Density Gap
The most significant technical hurdle is the energy density gap. Current leading structural battery prototypes from institutions like Chalmers University have achieved impressive results, but their energy density still lags far behind traditional lithium-ion technology. Significant breakthroughs in material science are required to close this gap and make SBCs competitive for long-range EVs.
Safety and Regulatory Frameworks
As a disruptive technology, structural battery composites do not fit neatly into existing standards. New protocols for testing, certification, and end-of-life management are urgently needed.
New Testing and Certification Protocols
Current automotive safety standards are designed for vehicles with inert structures and separate, contained battery packs. There are no established protocols for crash-testing a vehicle whose chassis is also its energy source. Engineers and regulators need to create new safety standards. They must develop tests to assess crashworthiness, the spread of heat in these distributed energy systems, and electrical safety during an impact. Before these cars can be approved for public roads, they will need extensive testing and validation.
Repair, Serviceability, and End-of-Life
The integrated design of structural batteries makes them difficult to repair. In a standard EV, a faulty battery module can be replaced. However, a damaged section of a structural battery panel cannot be easily swapped out. Because the battery is part of the car's structure, a minor collision damaging a component like the floor pan could require replacing the entire part. This might be so expensive that the vehicle is not worth repairing. Recycling these composites is also a major hurdle. The materials are tightly bonded together, and separating the carbon fibers, polymers, and active battery components requires advanced processes that are still under development.
Market Outlook and Future Projections
Despite the existing challenges, the market for structural battery composites is poised for explosive growth. Driven by relentless demand for lighter and more efficient energy storage solutions, this nascent market is on a trajectory to become a multi-billion dollar industry within the next decade, reshaping supply chains and creating new leaders in the automotive, aerospace, and electronics sectors.
Market Size and Growth Trajectory
Market analyses converge on a bullish outlook, predicting a dramatic expansion from a niche, research-focused field to a significant industrial segment. Several forecasts project the market will surge from under USD 250 million in 2025 to approach or exceed USD 1 billion by 2032. This rapid expansion is underpinned by an anticipated Compound Annual Growth Rate (CAGR) of between 21% and 25% from 2025 to 2032. This growth reflects the technology's transition from the laboratory to early-stage commercial applications, driven by escalating demand for lightweighting in high-value industries.
Regional Market Drivers
The global adoption of structural batteries will be led by three key regions, each with unique strategic advantages that will fuel innovation and market growth.
- North America: This region is expected to be a significant market, largely driven by the U.S. aerospace and defense sectors and the presence of EV pioneers like Tesla and General Motors who are actively innovating in battery integration. Government initiatives to boost domestic advanced battery production further strengthen its position.
- Europe: Driven by some of the world's most stringent emissions regulations, Europe is a key hub for automotive R&D. German automakers such as BMW and Volkswagen, along with Swedish innovators like Northvolt and the research community at Chalmers University, place the region at the forefront of developing sustainable transportation solutions.
- Asia-Pacific: The Asia-Pacific region is poised to hold the largest market share, anchored by its dominance in global battery manufacturing and a rapidly expanding EV market. Countries like China, Japan, and South Korea, home to key material suppliers and battery giants like CATL, LG Chem, and BYD, are leading the charge in both production and policy support.
Key Application Segments
While the long-term vision for structural batteries includes a wide array of products, the initial market growth will be concentrated in sectors where the benefits of weight reduction are most critical.
Automotive applications are expected to dominate the market as EV manufacturers aggressively pursue weight savings to extend vehicle range.
- Automotive: Expected to be the largest and fastest-growing segment, the automotive industry's push for longer-range EVs makes it the primary driver for structural battery composites.
- Aerospace & Defense: This sector will be a critical early adopter. For aircraft, drones, and satellites, every gram saved translates into significant gains in fuel efficiency, payload capacity, or flight time, justifying the higher initial material costs.
- Consumer Electronics: While a smaller initial market, the potential for thinner, lighter, and more durable laptops, tablets, and other devices represents a significant future growth area as manufacturing costs decrease.
The development of structural battery composites represents a pivotal moment in the evolution of electric transportation and beyond. It signals a fundamental shift away from the century-old paradigm of assembling separate, single-function components and toward a future built on smart, multifunctional, and deeply integrated materials. The vehicle ceases to be a container for a battery; the vehicle becomes the battery.
While significant challenges in cost, manufacturing, and energy density must still be overcome, the trajectory is clear. The potential benefits in weight reduction, range extension, design freedom, and safety are too transformative to ignore. These advantages create a powerful incentive for the continued investment and innovation needed to bring this technology into the mainstream.
The path to widespread adoption will be phased and strategic. We can expect to see the first commercial applications emerge in niche, high-value sectors like aerospace, performance vehicles, and drones, where the premium on weight savings justifies the initial cost. Following this, a hybrid approach will likely enter the automotive mainstream, with semi-structural components working alongside conventional battery packs to deliver early weight-saving benefits. As the technology matures and costs decline post-2026, we will move closer to the ultimate goal: a fully integrated, energy-storing chassis for mass-market EVs.
Ultimately, structural battery composites are more than just a better battery; they are a key enabling technology for the next generation of sustainable and highly efficient mobility. They promise to redefine the very architecture of our machines, paving the way for lighter, safer, and longer-range electric vehicles that will accelerate the global transition to clean energy.
