Digital Product Passport for Energy Storage (ESS)

Energy Storage (ESS) fall under the EU Ecodesign for Sustainable Products Regulation (ESPR 2024/1781). Home and industrial energy-storage systems built around batteries above 2 kWh fall under the EU Battery Regulation, mandatory from 18 February 2027. This page covers what that means in practice: the timeline, the data a passport must carry, who is legally responsible, and how to get ready.

Bottom line: Industrial and stationary batteries above 2 kWh are covered by the EU Battery Passport (Regulation 2023/1542). The passport must stay reachable for up to 15 years through an independent backup provider, and every registered version must carry a qualified electronic seal.

When it applies

Home and industrial energy-storage systems built around batteries above 2 kWh fall under the EU Battery Regulation, mandatory from 18 February 2027. The precise data set for energy storage is fixed by a delegated act under ESPR — the framework is law since July 2024; the sector detail arrives act by act. The central EU DPP Registry opened for registration on 19 July 2026, so identifiers can be filed as each group's rules take effect.

What the passport must carry

Across product groups the passport draws from the same families of data. For energy storage, expect:

battery identity, category and chemistry
capacity, power and performance data
recycled content of key materials
carbon footprint and performance class
state of health and durability
due-diligence and end-of-life information

Each claim needs its evidence — a certificate or test report with traceable provenance, not just a stated value. Market-surveillance and customs authorities can inspect the record.

Who is responsible

The manufacturer or EU importer of the storage system carries the obligation. The duty cannot be delegated: if a platform registers the passport on your behalf, you — the economic operator placing the product on the EU market — remain accountable.

How to prepare

ESS makers often integrate third-party cells, so cell-level data must flow up from the cell supplier into the system passport. PassPer builds the passport from the documents you already hold — spec sheets, certificates, supplier declarations — with AI extraction and human review, then handles the GS1 Digital Link carrier, the registry filing and the long-term hosting.

Frequently asked questions

Is a Digital Product Passport mandatory for energy storage?

Home and industrial energy-storage systems built around batteries above 2 kWh fall under the EU Battery Regulation, mandatory from 18 February 2027. It becomes mandatory when the ESPR delegated act for the group takes effect; the framework regulation is already in force and the EU registry is open.

Who needs the passport — the manufacturer or the importer?

The economic operator that places the product on the EU market. For goods made outside the EU, that is normally the importer or an appointed authorised representative.

How long must the passport stay available?

Up to 15 years, via an independent backup provider — the passport must outlive the product and, if necessary, the vendor that issued it.
