ENERGY LAW AND CROSS-BORDER HYDROGEN INFRASTRUCTURE LAW

Introduction

Cross-Border Hydrogen Infrastructure Law is an emerging branch of energy law dealing with the legal regulation of hydrogen infrastructure that crosses national boundaries. It covers hydrogen pipelines, storage facilities, ports, terminals, liquefaction or conversion facilities, hydrogen carriers such as ammonia and methanol, and interconnected electricity and renewable-energy systems used for hydrogen production.

Hydrogen is increasingly considered an important component of energy transition because it can potentially decarbonise sectors that are difficult to electrify directly, including heavy industry, shipping, aviation fuels and certain industrial processes. However, international hydrogen trade creates complex legal questions concerning infrastructure access, environmental standards, customs, transit rights, safety, investment protection, state responsibility and dispute settlement.

1. Meaning of Cross-Border Hydrogen Infrastructure Law

Cross-border hydrogen infrastructure law refers to the collection of domestic, regional and international legal rules governing the development, operation, financing, ownership, access and regulation of hydrogen infrastructure extending across two or more jurisdictions.

It may include:

Cross-border hydrogen pipelines;

Hydrogen import and export terminals;

Hydrogen storage facilities;

Ammonia and liquid-organic-hydrogen-carrier infrastructure;

Hydrogen ports and shipping facilities;

Cross-border renewable-electricity infrastructure supporting hydrogen production;

Compression, liquefaction and conversion facilities;

Interconnection between national hydrogen networks; and

Hydrogen transportation and distribution systems.

The legal framework must coordinate the laws of the exporting, transit and importing countries.

2. Importance of Cross-Border Hydrogen Infrastructure

Hydrogen production and consumption are often geographically separated. Countries with abundant renewable resources may produce hydrogen at relatively large scale, while industrialised countries may have greater demand.

Cross-border infrastructure therefore becomes important for:

international hydrogen trade;

energy security;

industrial decarbonisation;

diversification of energy supplies;

development of renewable-energy resources;

regional energy integration;

reduction of supply-chain risks; and

long-term investment in hydrogen infrastructure.

The legal challenge is to create predictable rules without preventing governments from regulating safety, environmental protection and public interests.

3. Hydrogen Pipelines and Transit Rights

Hydrogen pipelines represent one of the most significant forms of cross-border infrastructure.

A pipeline project may pass through:

the territory of the producing State;

a transit State; and

the territory of the consuming State.

Therefore, agreements may be required concerning route approval, land acquisition, construction permits, technical standards, maintenance, emergency response and liability.

A cross-border pipeline treaty may establish:

rights of transit;

ownership of the pipeline;

access conditions;

tariffs;

capacity allocation;

technical standards;

safety obligations;

environmental requirements;

emergency procedures;

inspection powers; and

dispute-resolution mechanisms.

4. Regulatory Harmonisation

Hydrogen infrastructure can be disrupted if neighbouring countries apply incompatible technical standards.

Harmonisation may therefore cover:

hydrogen purity;

pressure standards;

pipeline materials;

metering;

compression;

storage;

leakage monitoring;

transportation;

certification; and

emergency procedures.

Regulatory cooperation is particularly important because hydrogen infrastructure may interact with existing natural-gas systems.

5. Third-Party Access

An important energy-law issue is whether privately or publicly owned hydrogen infrastructure must provide access to competing suppliers.

Third-party access rules may promote competition by preventing infrastructure owners from excluding competitors.

Possible regulatory models include:

A. Regulated Third-Party Access

The regulator determines access conditions and potentially tariffs.

B. Negotiated Third-Party Access

Infrastructure users negotiate access conditions with the infrastructure owner.

C. Exempt Infrastructure

Certain new infrastructure may receive temporary exemptions from ordinary access requirements in order to encourage investment.

The appropriate model depends upon the maturity of the hydrogen market and the need to balance competition with infrastructure financing.

6. Cross-Border Hydrogen Certification

Certification is a central legal issue.

Different jurisdictions may use different definitions of:

renewable hydrogen;

low-carbon hydrogen;

clean hydrogen;

green hydrogen; and

hydrogen-derived fuels.

A cross-border hydrogen market requires mechanisms capable of demonstrating the origin and environmental characteristics of hydrogen.

Certification systems may address:

production method;

electricity source;

carbon intensity;

temporal correlation;

geographical correlation;

emissions during transportation; and

chain of custody.

Without compatible certification systems, hydrogen produced in one country may not qualify for incentives or regulatory recognition in another country.

7. Environmental Regulation

Hydrogen infrastructure can have environmental impacts even where the hydrogen itself is intended to reduce greenhouse-gas emissions.

Environmental regulation may concern:

land acquisition;

biodiversity;

water consumption;

renewable-energy development;

pipeline construction;

methane or hydrogen leakage;

ammonia handling;

marine impacts;

hazardous-material transportation; and

decommissioning.

Cross-border projects therefore commonly require environmental impact assessment and cooperation between environmental authorities.

8. Hydrogen Storage and Cross-Border Liability

Hydrogen may be stored in:

underground formations;

salt caverns;

tanks;

converted industrial facilities; and

specialised storage terminals.

Cross-border storage creates questions concerning ownership, leakage, contamination, monitoring and liability.

International agreements should specify which State has jurisdiction over an incident and which party bears responsibility for damage.

9. Ports and Hydrogen Carriers

Hydrogen may be transported internationally in forms that are easier to ship, particularly ammonia or other hydrogen carriers.

Port infrastructure may require:

specialised storage tanks;

loading and unloading facilities;

safety zones;

emergency-response systems;

customs procedures;

hazardous-material controls; and

environmental monitoring.

The legal framework must coordinate energy law with maritime, customs, environmental and transport law.

10. Investment Protection

Cross-border hydrogen infrastructure requires substantial capital investment.

Investors may seek protection against:

unlawful expropriation;

discriminatory treatment;

arbitrary regulatory measures;

breach of contractual obligations; and

restrictions on transfer of funds.

Investment treaties and infrastructure agreements may provide protections, but States normally retain regulatory powers concerning health, safety, environment and energy policy.

11. Energy Charter Treaty and Hydrogen Projects

International investment law may become relevant to hydrogen infrastructure where investors and host States are parties to applicable investment treaties.

However, treaty coverage, definitions of investment, applicable standards and dispute mechanisms must be examined carefully in each project.

Hydrogen infrastructure agreements should therefore clearly identify:

applicable law;

contractual obligations;

sovereign regulatory powers;

force majeure;

change in law;

termination;

compensation; and

dispute settlement.

12. Cross-Border Energy Infrastructure and State Sovereignty

A major legal principle is that States retain sovereignty over infrastructure located within their territory.

Accordingly, a cross-border hydrogen agreement cannot simply disregard domestic:

planning law;

environmental law;

property law;

energy regulation;

safety law;

taxation;

customs rules; and

public procurement requirements.

International cooperation must therefore operate together with domestic legal authority.

13. Customs and Trade Law

Hydrogen and hydrogen carriers crossing borders may be subject to customs and trade regulations.

Legal issues can include:

classification of hydrogen products;

customs valuation;

tariffs;

border procedures;

export controls;

technical barriers to trade;

non-discrimination; and

recognition of foreign certification.

Trade rules become particularly important where States establish subsidies or preferential treatment for domestically produced hydrogen.

14. Cross-Border Electricity and Hydrogen Production

Many hydrogen projects depend upon renewable electricity.

A cross-border project may therefore involve both:

Electricity infrastructure → Renewable generation → Electrolysis → Hydrogen infrastructure → Export → Import → Industrial consumption

The legal framework must coordinate electricity-market regulation with hydrogen regulation.

Questions may include:

who owns renewable assets;

whether electricity qualifies as renewable;

how electricity origin is certified;

grid-access rights;

transmission charges;

curtailment;

congestion management; and

responsibility for balancing.

15. Public International Law

Public international law provides important principles for cross-border infrastructure.

Relevant principles include:

territorial sovereignty;

peaceful cooperation;

good faith;

prevention of transboundary harm;

environmental due diligence;

treaty obligations; and

peaceful dispute settlement.

Where infrastructure causes damage across an international boundary, questions of attribution and State responsibility may arise.

16. Dispute Resolution

Cross-border hydrogen projects should contain carefully drafted dispute-resolution mechanisms.

Possible mechanisms include:

Negotiation;

Expert determination;

Mediation;

Commercial arbitration;

Investment arbitration;

Domestic courts; and

International courts where jurisdiction exists.

Dispute clauses should address governing law, seat of arbitration, applicable institutional rules, emergency relief and enforcement of awards.

17. Relevant Case Laws

1. Trail Smelter Arbitration (United States v. Canada)

The Trail Smelter Arbitration established an important principle concerning transboundary environmental harm. The dispute involved pollution originating in Canada and causing damage in the United States.

Legal Principle: A State may have international responsibility where activities within its territory cause significant transboundary harm.

Relevance to Hydrogen: Cross-border hydrogen pipelines, storage facilities and hydrogen-carrier terminals should be designed and operated with safeguards against transboundary environmental damage.

2. Pulp Mills on the River Uruguay (Argentina v. Uruguay), ICJ

The International Court of Justice considered environmental obligations associated with activities capable of affecting another State.

Legal Principle: States have procedural and substantive environmental obligations in relation to potentially transboundary activities, including cooperation and environmental assessment in appropriate circumstances.

Relevance to Hydrogen: Large cross-border hydrogen projects may require environmental assessment, information exchange and cooperation between neighbouring States.

3. Gabčíkovo-Nagymaros Project (Hungary v. Slovakia), ICJ

The dispute concerned a major transboundary infrastructure project involving the Danube River.

Legal Principle: International infrastructure agreements must be interpreted alongside evolving environmental considerations, while treaty obligations remain legally significant.

Relevance to Hydrogen: Long-term hydrogen infrastructure treaties must accommodate environmental developments and technological changes while maintaining legal certainty.

4. Certain Activities Carried Out by Nicaragua in the Border Area (Costa Rica v. Nicaragua), ICJ

The ICJ examined issues concerning activities in border areas and transboundary environmental effects.

Legal Principle: States must respect territorial rights and relevant environmental obligations when conducting activities near or affecting another State.

Relevance to Hydrogen: Cross-border hydrogen pipelines and terminals require careful treatment of territorial boundaries and environmental impacts.

5. Methanex Corporation v. United States

This investment arbitration concerned regulatory measures affecting an investor's commercial interests.

Legal Principle: Investment protection does not necessarily prevent States from adopting bona fide public-interest regulation.

Relevance to Hydrogen: Investors in
