Planned Pilot Project

AHS and H2Green Oil are preparing a pilot installation at a wind and photovoltaic site in Dörrieloh, Lower Saxony.

The planned configuration combines:

• A 1 MW electrolyser

• Renewable electricity from local wind and solar generation

• An AHS hydrogenation unit with a capatiy of 500kg H2 per day

The project is currently in preparation. Commissioning, continuous operation and independently verified performance data have not yet been reported.

Role in the eSAF Value Chain

AHS is positioned within the renewable-hydrogen storage and logistics layer of the eSAF ecosystem. Its technology could help bridge temporal and geographical gaps between decentralised electrolysis and industrial hydrogen demand.

AHS does not produce eSAF. Integration into a fuel-production project requires additional infrastructure for hydrogen release, purification, process heat and downstream synthesis.

At its present maturity, the AHS platform is suited to development, pilot and demonstration environments. Future industrial deployment will depend on successful validation, operating experience and project-specific technical and economic assessment.

Collaboration Opportunities

Potential interfaces within the eSAF Alliance include:

• renewable-energy and electrolyser developers

• Hydrogen-system integrators

• LOHC logistics and carrier-management providers

• Dehydrogenation and gas-conditioning specialists

• PtL and eSAF project developers

• Industrial sites with suitable process heat

• Research and engineering organisations supporting validation and scale-up

Initial collaboration can address pilot design, renewable-power integration, hydrogen-quality requirements, heat integration and the comparison of storage and transport options for decentralised PtL projects.

Areas of Expertise

• LOHC hydrogenation

• Benzyltoluene-based hydrogen storage

• Modular hydrogenation units

• Decentralised renewable hydrogen integration

• Hydrogen buffering

• Liquid-carrier logistics

• Electrolyser and storage integration

• Pilot and demonstration system development

• Process and heat-integration concepts

• ONEReactor technology background

Development and Regulatory Context

Deployment in an eSAF or Power-to-Liquid project requires assessment of renewable-hydrogen eligibility, electricity sourcing, hydrogen purity, carrier handling, energy demand, process heat, plant safety, transport configuration and lifecycle emissions.

An LOHC storage step does not independently establish RFNBO compliance. Eligibility depends on the complete production, transport and custody chain under the applicable European framework.

Company Overview

Advanced Hydrogen Storage GmbH (AHS) develops modular technology for storing hydrogen in Liquid Organic Hydrogen Carriers. Its current development focus is a hydrogenation unit designed to bind up to 500 kg of hydrogen per day in the liquid carrier material benzyltoluene.

The approach addresses decentralised hydrogen production sites where renewable electricity is available while direct access to hydrogen pipelines remains limited. Hydrogen from electrolysis can be chemically bound in the liquid carrier, stored and transported for subsequent use at another location.

AHS reports a current technology maturity of TRL 7–8. An improved hydrogenation-unit configuration is under development and requires further engineering and validation before commercial deployment.

Contribution to the eSAF Ecosystem

eSAF production requires a dependable supply of renewable hydrogen. Electrolyser output may fluctuate with wind and solar generation, while downstream conversion processes generally benefit from stable feed conditions.

LOHC systems can provide intermediate storage and connect decentralised hydrogen production with industrial consumption sites. This may be useful for PtL projects where a dedicated hydrogen pipeline is unavailable, delayed or unsuitable during an early project phase.

Within the eSAF value chain, AHS can contribute to:

• Intermediate storage of decentralised renewable hydrogen

• Integration of electrolysis with fluctuating wind and solar generation

• Transport of chemically bound hydrogen

• Buffering between hydrogen production and downstream demand

• Modular pilot and demonstration projects

Project suitability depends on hydrogen volume, transport distance, carrier circulation, hydrogen purity, heat integration and the energy demand of the complete storage cycle.

Technology and Project Status

AHS currently focuses on the hydrogenation and storage side of the LOHC cycle. During hydrogenation, hydrogen is chemically bound to benzyltoluene in an exothermic process. Subsequent hydrogen release requires a separate endothermic dehydrogenation step at the destination.

According to AHS, the technology is based on a licence from Hydrogenious LOHC Technologies. The broader technology background includes the ONEReactor concept, which combines hydrogenation and dehydrogenation functions within a single reactor architecture. The current AHS development programme centres on a dedicated hydrogenation unit.

AHS states that the underlying reactor concept has been tested over several years in a Fraunhofer research environment. Prof. Dr. Patrick Preuster, a shareholder of AHS, contributed to the development of the ONEReactor concept and has extensive experience in LOHC systems, chemical hydrogen storage and dynamic process engineering.

Editorial Development Note – 13 October 2026

At the editorial cut-off date, no AHS-built commercial-scale installation in continuous customer operation had been publicly documented. The underlying LOHC principles and reactor concepts are supported by published research, testing and third-party development work. Operational validation and scale-up of the AHS-specific system remain in progress.
