How the EU’s CBAM Affects the Solar Energy Storage Battery Businesses

Table of Contents

The EU’s Carbon Border Adjustment Mechanism (CBAM) is the bloc’s most ambitious climate rule so far. It aims to keep competition fair. EU manufacturers already pay carbon costs under the Emissions Trading System (ETS). Many foreign companies don’t. CBAM closes that gap. It is already changing how green energy products move in global trade. Initially, CBAM was applied only to heavy industries, such as cement and steel. Now the scope is growing. The European Solar Manufacturing Council (ESMC) aims to include solar products. They are calling for batteries, wafers, and ingots to be covered, too. This means battery materials could be next under CBAM rules.

We have worked on lithium batteries for 15 years. In that time, we stayed committed to sustainable growth. We built environmental care and social responsibility into daily operations. Now I’ll explain how CBAM works. I’ll show why it matters for green products. And I’ll share how you can turn compliance pressures into growth opportunities.

What is CBAM?

The Carbon Border Adjustment Mechanism (CBAM) is an important tool introduced by the European Union to price the embedded carbon emissions in imported goods.

Core Objective: To Ensure a Level Playing Field and Prevent "Carbon Leakage".

Its goal is to establish a fair price for carbon emissions generated during the production of certain imported goods, encourage other countries to adopt cleaner production methods, and create a level playing field for local producers who already pay carbon costs under the EU Emissions Trading System (ETS).

Key Timeline Milestones

On October 1, 2023, CBAM entered its transitional phase. Importers must now meet reporting obligations. From 2026 to 2034, the EU will roll out the full mechanism in stages. During this time, free allowances under the Emissions Trading System (ETS) will shrink. By 2034, they will disappear completely. In this stage, importers need to buy and surrender CBAM certificates.

Certificate Purchase and Surrender

The purchase and surrender of CBAM certificates form the core of the EU Carbon Border Adjustment Mechanism. In practice, this step directly affects importers’ costs and compliance status. So, how can companies get these certificates? Importers can use several main channels:
  • Designated trading platforms in EU member states (for example, Germany’s DEHSt or France’s DGEC)
  • The EU’s centralized CBAM Registry
  • Authorized brokers certified by the EU
In addition, companies must work with EU-accredited institutions to verify their product’s carbon footprint. They also need to complete carbon cost accounting in the country of origin. After that, they must prepare declaration materials carefully, especially by using accurate HS codes. Overall, this process is not quick. On average, it takes one to two months.

The Connection Between CBAM and Solar Energy Storage Batteries

Although solar energy storage battery systems are seen as “green products,” their manufacturing process can still produce significant carbon emissions. In fact, this issue lies at the center of CBAM’s concerns. Therefore, companies in this sector need to pay close attention to how their products are evaluated under the mechanism.

The Core of CBAM: Focus on "Embedded Carbon Emissions" in Products

CBAM does not target the “green attributes” of products themselves or their clean benefits during the usage phase, but rather focuses on the carbon emissions generated during the production and manufacturing process—known as “embedded carbon emissions.” For lithium-based products such as solar photovoltaic panels and energy storage batteries, their production process heavily relies on energy-intensive raw materials covered by CBAM. For example:
  • Polysilicon, a core material in photovoltaic modules, requires an extremely energy-intensive manufacturing process that consumes significant electricity.
  • Energy storage battery systems extensively use CBAM-covered aluminum and steel for components such as exterior casings, brackets, and container structures.
  • The electrolytic smelting of aluminum is one of the most energy-consuming industrial processes globally.

In summary, although solar energy storage battery products are not yet directly covered by CBAM, the carbon emissions from their upstream supply chains are already indirectly affected by the mechanism, impacting importers and distributors of these products.

Solar Energy Storage Importers and Distributors are Affected

Rising Costs:

CBAM will impose carbon costs based on the embedded emissions of imported goods. Suppliers that use carbon-intensive energy will face higher costs. These costs will raise prices and put pressure on the budgets of small and medium-sized installers and distributors.

Data and Reporting Obligations:

Importers must collect and verify suppliers’ product carbon footprint data. However, this task becomes complex when there is no standardized reporting. As a result, the lack of carbon transparency will turn into a major barrier to trade.

Market Competitiveness Restructuring:

Low-carbon products will gain a clear competitive advantage. Taking photovoltaic modules as an example:
  • Manufactured using coal power: carbon intensity ≥ 60 kg CO₂e/kW
  • Manufactured using renewable energy: carbon intensity ≤ 20 kg CO₂e/kW
The difference in CBAM cost between the two can reach €3.6/kW.

CBAM and the EU Battery Regulation: A Dual Regulatory Overlap

The EU’s Battery and Waste Battery Regulation took effect on August 17, 2023. Starting on August 18, 2025, it will fully replace the old Battery Directive.
For the lithium battery industry, CBAM and the New Battery Law must be considered together. When combined, they create an “overlapping regulatory effect.”

To respond, you can take several measures. These steps will help you handle the dual pressure more effectively.

Focus on the Total Cost of Ownership (TCO)

In the future, buyers need to make procurement decisions more rationally. At first, batteries with a lower carbon footprint may cost a bit more. However, they help avoid future risks from carbon cost swings or regulatory penalties. In the long run, they often deliver better total costs.

Collaborate with supply chain partners on emission reduction

Proactively communicate with battery manufacturers and upstream material suppliers. Together, explore ways to cut emissions. For example, you can support suppliers in using green electricity, improve production processes, and increase the use of recycled materials.
This is not only about meeting regulatory requirements. More importantly, it is a key step to building a supply chain that is long-term, stable, and green.

Turn Compliance into a Market Advantage:

Position products that meet CBAM and the New Battery Law as proof of environmental performance and sustainability. In this way, compliance becomes part of your brand story.
As a result, you can attract consumers and business partners who care about the environment. For example, if your energy storage systems use low-carbon batteries, that alone is a strong selling point. You can also highlight their role in protecting the environment when you talk to end users.

Conclusion​

CBAM is not just a simple trade barrier. Instead, it reshapes global rules during the shift to a carbon-neutral era. As a result, it changes how countries compete in trade. It does this by tying carbon emission costs directly to the competitiveness of products.
For solar storage battery manufacturers, this moment calls for a clear decision. Simply reacting to regulations will only increase costs and risks. But taking proactive steps now can establish your leadership in the emerging market.
