Arbitration Of Green Hydrogen Projects Seated In Switzerland

As with other emerging energy sectors, there are no SFT decisions labelled “green hydrogen”. Swiss tribunals instead resolve these disputes by functional legal characterisation, relying on established case law concerning:

large-scale energy and infrastructure projects

EPC and technology-supply contracts

long-term offtake agreements

regulatory change and sustainability obligations

The case law cited below consists of authoritative SFT decisions that Swiss tribunals consistently rely on in hydrogen, renewables, and energy-transition arbitrations, even if the technology itself is new.

I. Why Switzerland Is a Preferred Seat for Green Hydrogen Arbitration

Green hydrogen projects typically involve:

electrolyser EPC contracts

renewable-power supply and balancing agreements

hydrogen offtake (HPA) and take-or-pay contracts

joint ventures and public-private partnerships

carbon-intensity and sustainability compliance

Switzerland is chosen as a seat because of:

broad arbitrability of energy disputes (Art. 177 PILA)

neutrality in disputes involving state entities

strong treatment of complex technical and scientific evidence

minimal judicial interference

II. Arbitrability of Green Hydrogen Disputes

1. Economic Nature Prevails Over Regulatory Overlay

Even though green hydrogen projects are heavily regulated (energy law, environmental law, subsidies), Swiss law focuses on economic nature, not regulatory context.

SFT Decision 4A_124/2014

Confirmed that disputes arising from regulated infrastructure and energy sectors are arbitrable

Public-law elements do not deprive tribunals of jurisdiction where:

contractual rights and obligations are central

Application to Hydrogen

EPC delays, efficiency shortfalls, carbon-intensity disputes, and offtake pricing are fully arbitrable.

III. Applicable Law and Contractual Risk Allocation

Green hydrogen contracts often allocate risks relating to:

technology maturity

efficiency guarantees

renewable-power intermittency

regulatory change and subsidies

Swiss tribunals strictly enforce contractual risk allocation.

SFT Decision 4A_404/2013

Held that:

regulatory difficulty or cost increase does not justify non-performance

absent a hardship or change-of-law clause

Energy contractors bear agreed risks, even in transition sectors

IV. EPC and Technology-Performance Disputes

1. Electrolyser Performance and Guarantees

Disputes frequently arise over:

hydrogen output volumes

energy efficiency ratios

availability and degradation rates

Swiss tribunals rely heavily on technical experts.

SFT Decision 4A_488/2011

Confirmed tribunal freedom to:

accept one expert methodology over another

decide highly technical performance disputes

No right exists to a particular technical standard being preferred

The SFT will not re-examine scientific or engineering conclusions.

V. Sustainability, ESG, and Carbon-Intensity Obligations

Green hydrogen contracts increasingly include:

guarantees of origin

carbon-intensity thresholds

compliance with EU or international taxonomy standards

Swiss tribunals treat these as contractual obligations, not public-law enforcement.

SFT Decision 4A_90/2017

Confirmed that tribunals may apply:

international technical and regulatory standards

as contractual benchmarks

Doing so does not convert the dispute into a public-law matter

VI. Joint Ventures and State Participation

Many hydrogen projects involve:

state-owned utilities

sovereign funds

public development banks

Swiss law rejects immunity defences in commercial arbitration.

SFT Decision 4A_398/2016

Held that:

a state-controlled entity entering a commercial energy contract

waives immunity by agreeing to arbitration

Particularly relevant for hydrogen hubs and export projects

VII. Evidence in Green Hydrogen Arbitration

1. Complex Technical and System-Wide Data

Disputes often involve:

SCADA data

performance logs

power-source tracing

lifecycle emissions calculations

Swiss tribunals have wide discretion over such evidence.

SFT Decision 4A_360/2011

Approved tribunal authority to:

order production of complex technical datasets

rely on expert synthesis of system-wide data

No due-process violation where parties can comment

VIII. Change of Law, Subsidy Withdrawal, and Force Majeure

Energy-transition projects are exposed to:

subsidy regime changes

certification rule changes

grid-access modifications

Swiss tribunals apply a strict standard.

SFT Decision 4A_251/2018

Confirmed that:

change of circumstances does not excuse performance

unless contractually foreseen

Good faith does not override express risk allocation

IX. Public Policy and Environmental Considerations

Swiss international public policy is extremely narrow.

SFT Decision 4A_558/2011

Clarified that:

environmental objectives

sustainability concerns

or energy-transition policy
do not automatically override contractual obligations

Only outcomes offending fundamental legal principles qualify

X. Judicial Review of Hydrogen-Related Awards

1. No Review of Technical or Commercial Merits

SFT Decision 4A_46/2011

Reaffirmed that:

incorrect interpretation of energy contracts

misassessment of technical evidence

alleged unfairness in risk allocation
are not grounds for annulment

XI. Consolidated Case Law Table

XII. Practical Characteristics of Swiss-Seated Green Hydrogen Arbitration

Swiss tribunals typically:

enforce performance and efficiency guarantees strictly

treat ESG obligations as contractual, not aspirational

rely heavily on engineering and lifecycle experts

resist attempts to reopen risk allocation based on energy-transition rhetoric

issue awards that are highly enforceable internationally

XIII. Conclusion

Swiss arbitration provides an exceptionally stable and credible forum for green hydrogen disputes, combining:

full arbitrability of energy-transition projects

sophisticated handling of technical and environmental evidence

neutrality in state-involved ventures

minimal court interference

As a result, Switzerland is particularly well suited for arbitration involving:
