ENNOH

What ENNOH does

ENNOH — the European Network of Network Operators for Hydrogen — is a Brussels-based, non-profit membership association established under EU law (Regulation 2024/1789 and TEN-E Regulation 2022/869) and officially launched in January 2024. It represents 37 Hydrogen Transmission Network Operators (HTNOs) plus two Associated Partners (including the Ministry of Cyprus) across 26 EU countries, and is the sole EU-mandated body responsible for coordinated planning, network code development, and regulatory support for Europe's emerging hydrogen transmission system. ENNOH became fully operational in 2025 after receiving opinions from ACER (December 2024) and the European Commission (April 2025) and adopting its final statutory documents in June 2025.

ENNOH's core outputs are regulatory deliverables rather than commercial products. Its System Planning & Modelling function produces the Ten-Year Network Development Plan (TYNDP), Cost-Benefit Analysis (CBA) methodologies, system needs assessments, and hydrogen scenario drafting, using PyPSA (an open-source Python power-system simulation framework) for modelling. The Market, Economics & Network Codes function develops future hydrogen market design and network code inputs. The System Operation & Transparency function delivers hydrogen quality monitoring (first biennial report published May 2026), emissions and cybersecurity recommendations, and a Union-wide transparency platform mandated by Regulation 1789/2024 and launching on 1 October 2026. Additional outputs include annual reports, position papers on the EU Grids Package and Clean Energy Investment Strategy, and joint deliverables with ENTSOG (such as the May 2026 de-risking report on hydrogen infrastructure financing).

ENNOH's revenue model is membership-fee based, paid by its 37 HTNO members and 2 Associated Partners — there is no commercial pricing. Its go-to-market is regulatory and institutional rather than commercial: it acquires mandate and authority through EU regulation, public consultations, stakeholder workshops, and deep working relationships with ENTSO-E, ENTSOG, and the EU DSO Entity. The organisation is governed by a General Assembly, a Board, and a President (Christoph von dem Bussche, MD of GASCADE Gastransport). The Secretariat is organised into three functional departments plus Communications, with approximately 12 staff listed publicly. ENNOH is GDPR-compliant under EU and Belgian data protection law.

Core offering

ENNOH is the EU-mandated association of Hydrogen Transmission Network Operators (HTNOs) that coordinates the planning, market design, and regulatory development of Europe's hydrogen transmission infrastructure. Its core deliverables include the Ten-Year Network Development Plan (TYNDP), hydrogen Network Codes, Cost-Benefit Analysis methodologies, and a Union-wide transparency platform mandated under Regulation (EU) 2024/1789. The organization also runs public consultations, stakeholder workshops, and biennial hydrogen quality monitoring reports to support the development of the internal hydrogen market.

Product overview

ENNOH (European Network of Network Operators for Hydrogen) is a membership association, not a product company. It provides coordination, planning, and regulatory services for hydrogen transmission network operators across Europe. The organization operates through three core functional departments: System Planning & Modelling (developing TYNDP, CBA methodologies, and infrastructure assessments), Market Economics & Network Codes (market design and regulatory support), and System Operation & Transparency (hydrogen quality monitoring, emissions tracking, and the upcoming EU-wide transparency platform). ENNOH's deliverables include publications such as the TYNDP, hydrogen quality monitoring reports, position papers on EU policy, and joint reports with ENTSOG on de-risking investment and infrastructure repurposing. All activities are conducted in fulfillment of mandates under EU Regulation 2024/1789 and the TEN-E Regulation.

Emerging players

• European Hydrogen Backbone (consortium): The European Hydrogen Backbone is a consortium of 31 gas TSOs (many overlapping with ENNOH membership) proposing hydrogen pipeline routes. It overlaps with ENNOH's TYNDP planning but is a project-promo consortium rather than a regulator-mandated body.

Direct peers

• EU DSO Entity: EU DSO Entity is the EU-recognised association for electricity distribution system operators, a direct structural analogue of ENNOH at the distribution level. ENNOH collaborates with it on cross-carrier system integration.
• ENTSOG (European Network of Transmission System Operators for Gas): The most direct peer: ENTSOG is the EU-mandated association for gas transmission system operators, mirroring ENNOH's structure and mandate for the gas vector. They co-publish joint deliverables (de-risking report, repurposing criteria) and share office premises in Brussels.
• ENTSO-E (European Network of Transmission System Operators for Electricity): ENTSO-E is the EU-mandated body for electricity TSOs, structurally identical to ENNOH in role and governance. ENNOH cooperates with ENTSO-E on cross-sector scenario development and integrated energy system planning.

Broad incumbents

• Hydrogen Council: Hydrogen Council is a global CEO-led initiative of ~140 companies across the hydrogen value chain. While not EU-mandated, it is comparable in convening and policy-shaping function, though oriented to demand-side and industrial decarbonisation rather than transmission planning.
• ACER (Agency for the Cooperation of Energy Regulators): ACER is the EU agency that opines on ENNOH's governance and oversees EU energy regulators. It is a regulatory counterparty rather than a direct peer, but comparable in institutional role as a coordinator of EU energy-system participants.
• GIE (Gas Infrastructure Europe): GIE is the broader European gas infrastructure association covering TSOs, DSOs, storage, and LNG operators. Many ENNOH members are GIE members; GIE operates more broadly across the gas value chain while ENNOH is hydrogen-specific.

Regional players

• Clean Hydrogen Partnership: The EU's public-private hydrogen R&D partnership (formerly FCH JU) funds hydrogen R&I projects across Europe. Comparable in EU hydrogen mandate but focused on R&D funding and pilots rather than transmission planning.

Others

• IRENA (International Renewable Energy Agency): IRENA produces global renewable and hydrogen analysis with policy advisory functions. Adjacent to ENNOH in shaping the macro context for hydrogen demand and electrolyzer deployment.
• IEA (International Energy Agency): IEA produces global energy analysis including hydrogen roadmaps and infrastructure outlooks. Comparable in analytical and convening role at the global level; not a peer in the EU-mandated coordinating sense but adjacent in hydrogen policy and data work.
