Civil Law and Cross-Border Hydrogen Economy Contract Disputes in Europe

1. Introduction

Cross-border hydrogen economy contract disputes in Europe arise when parties located in different countries enter into agreements concerning the production, purchase, sale, transport, storage, conversion, certification, financing, infrastructure or use of hydrogen.

Examples include:

a German company purchasing renewable hydrogen from a Spanish producer;

a Dutch electrolyser operator supplying hydrogen to Belgium;

a French industrial consumer entering into a long-term hydrogen supply agreement with a Portuguese producer;

cross-border hydrogen pipeline transportation;

hydrogen storage agreements;

ammonia or methanol contracts connected with hydrogen production;

hydrogen offtake agreements;

electrolyser construction and operation contracts;

hydrogen certification and guarantees of origin;

hydrogen infrastructure connection agreements;

hydrogen project joint ventures;

cross-border hydrogen purchase and sale agreements.

Hydrogen contracts are unusual because ordinary civil and commercial contract law operates together with a rapidly developing EU energy-regulatory framework.

Directive (EU) 2024/1788 establishes common rules for the internal markets for renewable gas, natural gas and hydrogen and expressly seeks to facilitate an open, competitive hydrogen market and cross-border trade. Regulation (EU) 2024/1789 complements this framework for network access and hydrogen-market infrastructure. (EUR-Lex)

A major difficulty is that there is still relatively little CJEU case law specifically concerning private hydrogen contracts. Consequently, established electricity and natural-gas authorities are particularly important analogies.

2. Meaning of a Hydrogen Economy Contract

A hydrogen-economy contract may concern the entire value chain:

Renewable electricity → Electrolyser → Hydrogen production → Certification → Storage → Pipeline/transport → Offtake → Industrial use

A dispute can arise at any point.

Typical contractual relationships

3. Why Cross-Border Hydrogen Disputes Are Complex

A single dispute can involve:

contract law;

EU energy law;

national hydrogen regulation;

private international law;

competition law;

State-aid law;

environmental law;

infrastructure regulation;

certification rules;

taxation;

arbitration;

sanctions;

force majeure;

construction law.

Therefore, a hydrogen contract cannot be analysed solely as an ordinary sale-of-goods agreement.

4. EU Hydrogen Market Framework

Directive (EU) 2024/1788 is particularly important.

It requires Member States to facilitate competitive and non-discriminatory hydrogen markets and states that national law should not unduly hamper cross-border trade in hydrogen. It also envisages the development of hydrogen trading and liquid trading hubs. (EUR-Lex)

The Directive also provides that customers should be free to purchase hydrogen from the supplier of their choice and, subject to applicable conditions, to have more than one supply contract. (EUR-Lex)

This regulatory framework can influence private contracts involving:

access;

connection;

supply;

switching;

billing;

market entry;

network use;

licensing.

5. Regulation (EU) 2024/1789

The complementary Regulation addresses the internal-market infrastructure framework and supports development of hydrogen markets.

It is particularly relevant to:

transmission infrastructure;

network access;

infrastructure planning;

cross-border hydrogen systems;

tariffs;

interconnection;

market integration. (EUR-Lex)

Thus, a contractual right to transport hydrogen may be affected by mandatory regulatory requirements.

6. Applicable Law

The Rome I Regulation is normally central to determining the law applicable to contractual obligations.

A commercial hydrogen supply contract may contain:

“This Agreement shall be governed by German law.”

Such a clause will normally be highly significant between commercial parties.

But the parties cannot contract out of all mandatory EU or national regulatory rules.

The court must therefore distinguish:

Contractual rules

from

Mandatory regulatory rules.

7. Jurisdiction

A cross-border hydrogen agreement should ideally contain a clear jurisdiction clause.

For example:

“The courts of Amsterdam shall have exclusive jurisdiction.”

The enforceability of such a clause must be assessed under the Brussels I bis Regulation, where applicable.

Alternatively, the parties may select arbitration.

8. Arbitration

Hydrogen projects are particularly suitable for international arbitration because:

projects involve multiple jurisdictions;

parties include international energy companies;

infrastructure is geographically dispersed;

technical disputes require expert evidence;

contracts can have long durations;

confidentiality may be important.

Typical clauses identify:

seat;

institution;

number of arbitrators;

governing law;

emergency relief;

expert determination;

technical disputes;

language.

9. Hydrogen Supply Agreement

A hydrogen supply agreement should normally define:

quantity;

delivery schedule;

pressure;

purity;

temperature;

delivery point;

specification;

renewable/low-carbon status;

certification;

price;

indexation;

balancing;

take-or-pay;

force majeure;

change in law;

termination;

liability.

Ambiguous specifications can generate major disputes.

10. Hydrogen Quality Disputes

Hydrogen can be supplied in different forms and qualities.

The contract may specify:

purity percentage;

contaminants;

pressure;

moisture;

temperature;

energy content;

delivery pressure;

certification status.

A buyer may reject a shipment because the hydrogen fails contractual specifications.

The dispute then becomes:

Was the hydrogen contractually conforming at the contractual delivery point?

Technical expert evidence will often be essential.

11. Quantity Disputes

Suppose the contract requires:

10,000 tonnes of hydrogen per year.

The producer supplies only 7,000 tonnes.

The parties may disagree about whether the shortfall was caused by:

equipment failure;

electricity shortage;

renewable-energy intermittency;

network congestion;

regulatory restrictions;

force majeure;

buyer's failure to take delivery.

The contract's allocation of production risk becomes crucial.

12. Take-or-Pay Clauses

Long-term hydrogen projects may use take-or-pay arrangements.

Under such a clause, the buyer agrees either:

to take a minimum quantity; or

to pay for the minimum quantity even if it does not physically take it.

Disputes may concern:

whether the clause is a genuine payment obligation;

whether force majeure applies;

whether the buyer has a right to suspend purchases;

whether alternative purchases should be credited;

whether the clause constitutes a penalty under applicable national law.

13. Price Disputes

Hydrogen prices may be linked to:

electricity prices;

natural-gas prices;

carbon prices;

inflation;

renewable-energy costs;

commodity indices.

A contract may contain a formula such as:

Hydrogen Price = Base Price + Electricity Component + Carbon Component + Adjustment

Disputes can arise when:

an index disappears;

government policy changes;

electricity prices become negative;

subsidies are withdrawn;

production costs rise;

the agreed formula produces commercially unexpected results.

14. Case Law 1 — Federutility

Case C-265/08, Federutility and Others

This is an important natural-gas authority that can be applied by analogy to hydrogen.

The case concerned State intervention in the pricing of natural-gas supply after market liberalisation.

The CJEU held that intervention in prices could be compatible with EU law only under strict conditions, including pursuit of a general economic interest and compliance with proportionality. (InfoCuria)

Hydrogen relevance

If a Member State imposes price controls or other public-service requirements affecting hydrogen supply, a court may need to consider:

legitimate public interest;

proportionality;

necessity;

market competition;

non-discrimination.

Classification

Analogical energy-market authority — not a hydrogen case.

15. Case Law 2 — ANODE

Case C-121/15, ANODE v Premier Ministre

The dispute concerned regulated natural-gas tariffs in France.

The CJEU examined whether State regulation of supply prices was compatible with the EU internal market.

The Court recognised that objectives such as security of supply and territorial cohesion can potentially justify State intervention, but the intervention must satisfy EU-law requirements and must not go beyond what is necessary. (curia)

Hydrogen application

This principle can become relevant where a Member State regulates:

hydrogen prices;

hydrogen supply obligations;

strategic hydrogen reserves;

vulnerable-consumer supply;

public-service hydrogen arrangements.

Classification

Analogical authority.

16. Case Law 3 — E.ON Földgáz Trade

Case C-510/13, E.ON Földgáz Trade v Hungarian Energy and Public Utilities Regulatory Authority

This case concerned access to the natural-gas transmission system and the right of an energy-market operator to challenge a regulatory decision.

The CJEU recognised the importance of effective judicial protection for market participants directly affected by regulatory decisions. (InfoCuria)

Hydrogen application

This is highly relevant to disputes concerning:

hydrogen pipeline access;

network capacity;

connection charges;

regulatory decisions;

refusal of network access;

capacity allocation.

A hydrogen trader or producer may need an effective mechanism to challenge a regulatory decision affecting its contractual business.

Classification

Strong energy-infrastructure analogy.

17. Case Law 4 — Commission v Hungary

Case C-771/18, Commission v Hungary

The case concerned charges for access to electricity and natural-gas transmission networks and the legal framework for setting those charges.

The CJEU emphasised the importance of regulatory rules concerning network-access charges and effective judicial protection. (InfoCuria)

Hydrogen application

The same issues can arise in future hydrogen infrastructure:

pipeline access charges;

connection fees;

transmission tariffs;

capacity charges;

storage charges.

A private hydrogen contract cannot necessarily override mandatory network-access regulation.

Classification

Analogical infrastructure authority.

18. Case Law 5 — PreussenElektra

Case C-379/98, PreussenElektra AG v Schleswag AG

This landmark renewable-energy case concerned German legislation requiring electricity suppliers to purchase electricity generated from renewable sources at minimum prices.

The CJEU considered both free movement and State-aid issues. (InfoCuria)

Hydrogen relevance

Hydrogen projects frequently depend on renewable electricity.

A hydrogen producer may therefore enter into:

renewable PPAs;

grid contracts;

renewable-electricity support arrangements;

hydrogen offtake contracts.

Government support mechanisms can affect the economics and enforceability of these arrangements.

Classification

Important renewable-energy analogy.

19. Case Law 6 — Ålands Vindkraft

Case C-573/12, Ålands Vindkraft AB v Energimyndigheten

The CJEU considered Sweden's renewable-electricity certificate system.

The Court held that EU renewable-energy legislation did not require Member States operating support schemes to extend those schemes to renewable electricity produced in another Member State. (curia)

Hydrogen application

Hydrogen producers may face similar questions concerning:

renewable hydrogen certification;

support schemes;

cross-border recognition;

subsidies;

guarantees of origin;

eligibility for national incentives.

A producer cannot necessarily assume that a national support mechanism automatically follows hydrogen produced in another Member State.

Classification

Strong analogy for renewable-hydrogen support and certification.

20. Case Law 7 — Komstroy

Case C-741/19, Republic of Moldova v Komstroy

This case concerned an arbitration dispute connected with a claim arising from a contract for electricity supply.

The CJEU held that a simple claim arising from an electricity-supply contract, without an underlying investment, did not constitute an “investment” for purposes of the Energy Charter Treaty.

The Court treated an ordinary electricity supply contract as a commercial transaction rather than automatically as an investment. (curia)

Hydrogen significance

This is extremely useful for distinguishing:

ordinary hydrogen sale contract

from

investment in a hydrogen project.

A long-term hydrogen supply agreement does not automatically become an investment merely because it relates to a strategic energy project.

Classification

Important energy-contract/investment-law analogy.

21. Case Law 8 — E.ON Földgáz and Effective Judicial Protection

The E.ON Földgáz jurisprudence is also significant because a market participant affected by a regulatory decision must have access to an effective legal remedy.

This becomes increasingly important as hydrogen markets develop and regulators determine:

network access;

capacity;

connection;

tariffs;

market participation.

The CJEU has linked these procedural protections with Article 47 of the Charter. (InfoCuria)

22. Case Law 9 — Commission v Netherlands, Italy, France and Spain

Joined Cases C-157/94 to C-160/94

These cases concerned national monopolies concerning import and export of electricity and gas.

The CJEU examined national restrictions on cross-border energy trade. (curia)

Hydrogen application

The cases provide historical foundations for the principle that national energy monopolies and restrictions must be assessed against EU free-movement principles.

For hydrogen, this matters because Directive 2024/1788 expressly seeks to prevent undue barriers to cross-border hydrogen trade. (EUR-Lex)

Classification

Foundational energy-market analogy.

23. Hydrogen Certification Disputes

Certification can become one of the most important areas of litigation.

The buyer may contract for:

“renewable hydrogen”

while the producer supplies hydrogen that does not qualify under the relevant EU certification framework.

Potential disputes include:

origin;

carbon intensity;

renewable-electricity sourcing;

temporal correlation;

geographic correlation;

chain of custody;

guarantees of origin;

sustainability documentation.

The question becomes:

Is certification merely regulatory documentation, or is it also a contractual specification?

If the contract incorporates the certification requirement, failure may constitute contractual non-performance.

24. Green Hydrogen vs Low-Carbon Hydrogen

Contracts should carefully distinguish:

Renewable hydrogen

Hydrogen produced under the applicable renewable-hydrogen framework.

Low-carbon hydrogen

Hydrogen meeting the applicable emissions-reduction requirements but not necessarily produced in the same way as renewable hydrogen.

Using the term “green hydrogen” without a contractual definition can create disputes.

A well-drafted contract should identify the precise regulatory standard.

25. Cross-Border Hydrogen Pipeline Contracts

Pipeline contracts may involve:

capacity reservation;

entry/exit points;

balancing;

pressure;

metering;

quality;

network losses;

maintenance;

outages;

interconnection.

A producer in Spain might contract to deliver hydrogen to Germany through infrastructure crossing:

Spain → France → Germany.

The dispute may involve several regulatory authorities and several national legal systems.

26. Hydrogen Storage Contracts

Hydrogen storage can involve:

salt caverns;

underground storage;

tanks;

converted gas infrastructure.

Contractual issues include:

storage capacity;

injection rights;

withdrawal rights;

losses;

contamination;

pressure;

leakage;

availability;

emergency withdrawal.

If the storage facility is located in another country, jurisdiction and applicable-law questions become important.

27. Electrolyser Contracts

Hydrogen production frequently depends on electrolysers.

An electrolyser contract may be:

equipment sale;

EPC contract;

technology licence;

operation and maintenance agreement;

performance guarantee.

Disputes can involve:

efficiency;

production capacity;

degradation;

electricity consumption;

commissioning;

availability;

warranty;

replacement.

28. Performance Guarantees

Suppose the contract promises:

Electrolyser efficiency of 75%.

Actual performance is only:

62%.

The buyer may claim:

breach of warranty;

price reduction;

repair;

replacement;

damages;

termination.

The contract should specify the testing methodology because technical measurement disputes can become central.

29. Hydrogen Infrastructure Construction Disputes

Hydrogen projects may involve major infrastructure:

pipelines;

terminals;

storage;

electrolysers;

compression facilities;

ports.

Construction disputes may concern:

delay;

defects;

design changes;

permits;

cost escalation;

change in law;

force majeure;

commissioning.

FIDIC-style contractual mechanisms may therefore become relevant.

30. Cross-Border Joint Ventures

Hydrogen projects frequently involve several companies.

For example:

Energy company + industrial company + infrastructure operator + financial investor

may form a joint venture.

Disputes can concern:

capital contributions;

board control;

deadlock;

technology contributions;

profit distribution;

exit rights;

dilution;

transfer restrictions.

The joint-venture agreement may be governed by one country's law while the project operates in another.

31. Offtake Agreements

An offtake agreement is a long-term commitment by a buyer to purchase hydrogen.

It may support project financing.

The buyer may promise:

minimum annual purchase;

fixed price;

indexed price;

take-or-pay;

long-term duration.

If the buyer terminates prematurely, the producer may claim substantial damages.

Conversely, if the producer fails to deliver, the buyer may seek:

replacement costs;

cover damages;

price difference;

termination.

32. Force Majeure

Hydrogen contracts need unusually detailed force-majeure provisions.

Potential events include:

electricity-grid failure;

electrolyser failure;

pipeline failure;

extreme weather;

war;

sanctions;

export restrictions;

regulatory prohibition;

shortage of renewable electricity;

cyberattack;

infrastructure outage.

The key question is:

Was the event outside the affected party's reasonable control and did the contract allocate that risk to force majeure?

33. Change in Law

Hydrogen regulation is developing rapidly.

A long-term contract may be signed under one regulatory regime and performed under another.

Possible changes include:

hydrogen definitions;

emissions thresholds;

certification rules;

network regulation;

subsidies;

taxation;

environmental requirements.

A sophisticated contract should therefore contain a change-in-law clause.

It can provide:

renegotiation;

price adjustment;

temporary suspension;

termination;

compensation.

34. Subsidy Withdrawal

Hydrogen projects may depend on:

national subsidies;

EU funding;

contracts for difference;

tax incentives;

renewable-energy certificates.

If the expected support disappears, parties may disagree about whether:

“loss of subsidy” = force majeure,

or

“loss of subsidy” = ordinary commercial risk.

Usually, the answer depends heavily on the contractual allocation of risk and the applicable national law.

35. State Aid and Hydrogen Projects

Government support may raise EU State-aid questions.

A private party should therefore distinguish:

Contractual entitlement

What the State or company promised.

Regulatory permission

Whether the scheme is legally permissible under EU law.

State aid compatibility

Whether public financial support complies with EU competition rules.

A contract cannot necessarily cure an unlawful State-aid arrangement.

36. Competition Law

Hydrogen markets are developing from a relatively concentrated industrial base.

Potential competition issues include:

exclusive supply agreements;

long-term offtake arrangements;

market allocation;

discriminatory network access;

refusal to supply;

infrastructure foreclosure;

information exchange.

A long-term hydrogen contract can therefore be both:

a private civil contract

and

an agreement subject to EU competition law.

37. Cross-Border Hydrogen Trading

Directive 2024/1788 specifically states that Member States should not unduly hamper cross-border trade in hydrogen and should facilitate market entry and exit. (EUR-Lex)

This has significant contractual consequences.

A national measure that makes a cross-border hydrogen contract impossible may need to be examined under:

EU energy law;

free-movement principles;

proportionality;

non-discrimination.

38. Network Access Disputes

Suppose:

Producer: Spain
Pipeline: France
Buyer: Germany

The producer has a supply contract with the German buyer but cannot obtain sufficient French pipeline capacity.

The resulting dispute may involve:

producer vs pipeline operator;

producer vs regulator;

producer vs buyer;

force majeure;

alternative transport;

contractual penalties.

E.ON Földgáz and Commission v Hungary provide useful analogies concerning regulated network access and effective remedies. (InfoCuria)

39. Hydrogen Delivery Point

The contract should identify precisely where delivery occurs.

For example:

“Delivery occurs when hydrogen enters the buyer's receiving pipeline.”

This determines:

risk transfer;

title;

measurement;

quality testing;

insurance;

transportation responsibility.

Unclear delivery points can generate major cross-border disputes.

40. Incoterms and Hydrogen

Where hydrogen is transported physically, parties may attempt to use standard commercial delivery concepts.

However, hydrogen has special technical characteristics.

The contract should therefore supplement ordinary commercial terms with provisions concerning:

pressure;

purity;

custody transfer;

metering;

certification;

pipeline connection;

storage.

41. Hydrogen Derivatives

Hydrogen may be converted into:

ammonia;

methanol;

synthetic fuels.

A dispute may therefore involve a contract formally concerning ammonia but economically connected to a hydrogen project.

Courts must identify the precise contractual obligation rather than automatically treating every hydrogen-related dispute as a hydrogen supply dispute.

42. Insurance

Hydrogen projects create unusual risks.

Insurance disputes can concern:

explosion;

leakage;

equipment failure;

business interruption;

construction risk;

transport;

environmental damage.

Cross-border projects may involve insurers governed by a different legal system from the project operator.

43. Liability for Hydrogen Leakage

Hydrogen leakage can produce:

property damage;

business interruption;

environmental claims;

infrastructure damage;

third-party injury.

Liability depends upon:

contract;

negligence;

statutory safety duties;

causation;

insurance.

A contract may allocate responsibility among:

producer;

transporter;

storage operator;

purchaser.

44. Cybersecurity

Modern hydrogen infrastructure may depend on:

automated controls;

SCADA systems;

smart meters;

digital pipeline management;

remote monitoring.

A cyberattack can therefore result in:

production interruption;

delivery failure;

physical damage;

data loss;

safety incidents.

The parties should define whether cyber incidents constitute:

force majeure;

contractual breach;

security incident;

compensable event.

45. Evidence

Hydrogen disputes may require highly technical evidence.

Important documents include:

production logs;

purity certificates;

measurement data;

pipeline records;

energy-consumption records;

electrolyser performance data;

certification documents;

meter readings;

maintenance reports;

engineering reports;

regulatory permits.

Experts may be required in:

hydrogen chemistry;

engineering;

pipeline operations;

renewable-energy accounting;

economics;

carbon accounting.

46. Damages

Possible damages include:

Direct loss

Cost of replacement hydrogen.

Cover damages

Additional cost of purchasing hydrogen elsewhere.

Lost profits

Where recoverable under applicable law.

Delay damages

For late commissioning or delivery.

Capacity damages

Loss arising from unused infrastructure.

Financing losses

Additional project-finance costs.

Termination damages

Loss arising from premature termination.

47. Penalty Clauses

Hydrogen contracts may contain:

delay liquidated damages;

shortfall penalties;

failure-to-take charges;

quality penalties;

availability penalties.

Whether such clauses are enforceable depends heavily on the applicable national law.

Some civil-law jurisdictions allow courts to reduce excessive penalties.

Therefore, the governing law should be checked before assuming that a contractual penalty is automatically enforceable.

48. Regulatory vs Contractual Dispute

This distinction is extremely important.

Contract dispute

“The hydrogen supplier failed to deliver.”

Regulatory dispute

“The regulator unlawfully denied pipeline capacity.”

Mixed dispute

“The supplier failed to deliver because the regulator denied pipeline access.”

The third situation requires analysis of both legal regimes.

49. Key Case-Law Table

50. The Most Important Six Cases

For examination purposes, six particularly useful authorities are:

1. E.ON Földgáz Trade — C-510/13

Rule: Energy-market participants affected by regulatory decisions require effective judicial protection. (InfoCuria)

2. Commission v Hungary — C-771/18

Rule: Network-access charges and regulatory remedies must comply with EU energy-law requirements. (InfoCuria)

3. ANODE — C-121/15

Rule: State intervention in energy prices must satisfy EU-law conditions, including proportionality.

4. Federutility — C-265/08

Rule: Public-interest price regulation in energy markets is subject to strict EU-law conditions. (InfoCuria)

5. PreussenElektra — C-379/98

Rule: Renewable-energy purchasing obligations must be assessed against EU free-movement and State-aid principles. (InfoCuria)

6. Komstroy — C-741/19

Rule: A simple energy-supply claim does not automatically constitute an investment under the Energy Charter Treaty. (curia)

Important: These cases are primarily energy-sector analogies, not judgments directly deciding private hydrogen supply-contract liability. Direct CJEU jurisprudence on private cross-border hydrogen contracts remains comparatively limited.

51. Hypothetical Example

Facts

A Spanish company produces renewable hydrogen.

A German steel manufacturer signs a 15-year offtake agreement.

The hydrogen must pass through French infrastructure.

The contract provides:

German law;

arbitration in Paris;

minimum annual quantity;

renewable-hydrogen certification;

take-or-pay obligation.

After five years:

French pipeline capacity becomes unavailable;

Spanish production falls;

certification rules change;

hydrogen prices rise sharply.

The German buyer refuses to pay the take-or-pay amount.

Legal Questions

Question 1 — Was there a supply breach?

The court must determine whether the producer was contractually obligated to deliver the minimum quantity.

Question 2 — Was pipeline unavailability force majeure?

The contract's force-majeure clause must be examined.

Question 3 — Who bears regulatory risk?

The change-in-law clause becomes important.

Question 4 — Is the hydrogen still contractually compliant?

Certification rules must be examined.

Question 5 — Is the take-or-pay clause enforceable?

The applicable German law determines the relevant civil-law rules.

Question 6 — Is arbitration available?

The arbitration clause determines the dispute-resolution mechanism, subject to applicable arbitration law.

Question 7 — Can the producer obtain pipeline access?

EU and national hydrogen-network rules may become relevant.

52. Contract Drafting Lessons

A cross-border hydrogen agreement should expressly address:

Product

hydrogen purity;

pressure;

temperature;

quality.

Quantity

minimum quantity;

maximum quantity;

tolerance;

balancing.

Certification

renewable;

low-carbon;

carbon intensity;

verification.

Price

fixed;

indexed;

adjustment formula.

Delivery

delivery point;

title;

risk;

measurement.

Regulation

permits;

regulatory changes;

subsidies.

Force majeure

electricity failure;

pipeline outage;

regulatory intervention;

cyberattack.

Liability

caps;

exclusions;

consequential loss.

Termination

persistent failure;

insolvency;

change in law;

prolonged force majeure.

Dispute resolution

court;

arbitration;

seat;

governing law;

technical expert determination.

53. Role of Good Faith

Good faith is relevant to:

contract interpretation;

cooperation;

notice;

mitigation;

renegotiation;

exercise of termination rights.

However, the exact legal effect of good faith varies between European legal systems.

A court should therefore identify the national law governing the contract rather than assuming that one uniform European doctrine of good faith applies.

54. Force Majeure vs Hardship

These concepts should be distinguished.

Force majeure

Performance becomes impossible or seriously prevented by an external event.

Hardship

Performance remains technically possible but becomes extraordinarily burdensome because circumstances have fundamentally changed.

Hydrogen contracts should ideally address both separately.

55. Long-Term Hydrogen Contracts

Hydrogen projects often require long-term contracts because producers need revenue certainty to finance infrastructure.

Long-term contracts therefore create tension between:

stability

and

regulatory/market change.

A 15- or 20-year contract may experience:

new hydrogen standards;

new carbon prices;

new taxes;

new infrastructure;

new certification rules;

technological change.

Contractual flexibility becomes essential.

56. Cross-Border Enforcement

After obtaining a judgment or arbitral award, the successful party may need to enforce it in another country.

Assets could include:

bank accounts;

hydrogen infrastructure;

shares;

receivables;

equipment.

For EU court judgments, Brussels I bis can provide the relevant recognition and enforcement framework.

For arbitral awards, the New York Convention is generally central.

57. Overall Legal Structure

A cross-border hydrogen contract dispute can be analysed using this sequence:

Step 1

Identify the parties.

Step 2

Classify the contract.

Step 3

Identify the hydrogen product/specification.

Step 4

Identify the delivery location.

Step 5

Determine jurisdiction.

Step 6

Determine governing law.

Step 7

Identify mandatory EU energy rules.

Step 8

Check national hydrogen regulation.

Step 9

Examine breach.

Step 10

Examine causation and damages.

Step 11

Consider force majeure/change in law.

Step 12

Apply arbitration or court procedures.

Step 13

Determine recognition and enforcement.

58. Conclusion

Cross-border hydrogen economy contract disputes in Europe sit at the intersection of civil contract law, energy regulation, private international law, infrastructure law, environmental regulation, competition law and arbitration.

The emerging EU hydrogen framework is expressly designed to facilitate an integrated hydrogen market and prevent undue barriers to cross-border hydrogen trade. Directive 2024/1788 specifically refers to cross-border hydrogen trade, market entry and exit, customer choice and the development of hydrogen trading markets. (EUR-Lex)

Because private hydrogen-contract jurisprudence is still developing, established electricity and natural-gas decisions provide important guidance. E.ON Földgáz, Commission v Hungary, ANODE and Federutility are particularly useful for network access, regulation and pricing; PreussenElektra and Ålands Vindkraft illuminate renewable-energy support and territorial issues; and Komstroy is important for distinguishing an ordinary energy-supply contract from an investment. (InfoCuria)
