ENERGY LAW AND HYDROGEN CERTIFICATION AND GUARANTEES OF ORIGIN

1. Introduction

Hydrogen certification and Guarantees of Origin (GOs) are regulatory systems used to verify how hydrogen was produced, what energy sources were used, and the greenhouse-gas emissions associated with its production. They are increasingly important because hydrogen may be produced from renewable electricity, natural gas, biomass, nuclear energy, or other sources with very different environmental impacts.

Energy law therefore requires credible certification so that governments, consumers, investors, and industrial buyers can distinguish renewable or low-carbon hydrogen from higher-emission alternatives. Certification supports subsidies, renewable-energy targets, carbon accounting, international trade, and protection against misleading environmental claims.

2. Guarantees of Origin

A Guarantee of Origin is an electronic certificate representing specified attributes of energy production. Under Article 19 of the EU Renewable Energy Directive (Directive (EU) 2018/2001, as amended), Guarantees of Origin may be issued for renewable energy, including gaseous renewable fuels of non-biological origin such as hydrogen. Generally, one GO represents 1 MWh of energy, and the same unit of renewable energy must not be counted more than once.

A GO normally records the energy source, production period, installation identity and location, commissioning date, support received, issuing country, and unique identification number. These rules create traceability and reduce double counting.

3. Certification versus Guarantees of Origin

Certification and GOs perform related but distinct functions. A GO primarily proves the origin and attributes of a particular quantity of energy. Certification may go further by confirming compliance with lifecycle greenhouse-gas thresholds, sustainability rules, production methodologies, and chain-of-custody requirements.

For hydrogen, certification may therefore examine electricity sourcing, electrolyzer operation, upstream emissions, transport, carbon capture, methane leakage, and other lifecycle factors.

Modern regimes increasingly use concepts such as additionality, temporal correlation, geographic correlation, mass balance, auditing, and lifecycle emissions calculation.

4. United Kingdom Framework

The United Kingdom's Low Carbon Hydrogen Standard (LCHS) establishes lifecycle greenhouse-gas accounting requirements and an emissions-intensity threshold for hydrogen seeking recognition as low carbon. Version 4 was published in January 2026 and includes updated rules concerning evidencing Renewable Energy Guarantees of Origin and other verification requirements.

The UK has also developed a Low Carbon Hydrogen Certification Scheme intended to provide reliable information concerning the environmental characteristics of hydrogen and facilitate domestic and international trade. The proposed framework is based on the LCHS and uses a mass-balance chain-of-custody approach.

5. Case Law: Ålands Vindkraft AB v. Energimyndigheten, Case C-573/12 (CJEU, 2014)

Case Name/Citation: Ålands Vindkraft AB v Energimyndigheten, Case C-573/12.

Facts: A Finnish wind producer sought access to Sweden's renewable-energy certificate support system.

Legal Issue: Whether Sweden could restrict its certificate support mechanism principally to electricity produced within Sweden.

Judgment: The Court of Justice accepted that national renewable-support schemes could, subject to EU-law requirements, operate territorially.

Legal Principle/Ratio: Renewable certificates and support mechanisms may constitute legitimate regulatory instruments for achieving national renewable-energy objectives.

Significance: The case is relevant to hydrogen certification because it demonstrates that certificate systems carry legal consequences concerning eligibility, territoriality, market access, and renewable-energy support.

6. Case Law: Essent Belgium NV v. Vlaamse Reguleringsinstantie, Joined Cases C-204/12 to C-208/12

Facts: Belgian rules granted advantages through green-certificate mechanisms while differentiating according to the origin of renewable electricity.

Legal Issue: Whether restrictions linked to certificate origin were compatible with EU free-movement rules.

Judgment: The Court recognized renewable-energy promotion as a legitimate objective but required restrictions to satisfy EU proportionality principles.

Legal Principle/Ratio: Environmental certificate schemes must be transparent, objectively justified, and proportionate.

Significance: Hydrogen GO systems must avoid arbitrary discrimination and ensure that cross-border recognition rules are legally defensible.

7. Anti-Fraud and Market Integrity

Certification registries must prevent double issuance, double counting, false carbon claims, certificate duplication, and fraudulent transfers. Electronic issuance, transfer, cancellation, independent auditing, and standardized registries are therefore essential.

These safeguards are particularly important for internationally traded hydrogen and derivatives such as ammonia or methanol.

8. Conclusion

Hydrogen certification and Guarantees of Origin combine energy law, climate regulation, consumer protection, emissions accounting, trade law, and market governance. Effective systems establish reliable traceability from production to consumption, prevent double counting, verify carbon intensity, and support credible environmental claims. As international hydrogen markets develop, harmonized certification and mutual recognition will become essential for determining which hydrogen qualifies for subsidies, renewable targets, industrial decarbonization obligations, and cross-border trade.
