Hydrogen Energy Applications for Valley Environments in Northern Netherlands

Periodic Reporting for period 2 - HEAVENN (Hydrogen Energy Applications for Valley Environments in Northern Netherlands)

Reporting period: 2021-01-01 to 2021-12-31

HEAVENN is a large-scale demo project addressing the requirements of the call, by bringing together core elements: production, distribution, storage and local end-use of H2 into a fully-integrated and functioning “H2 valley” (H2V), that can serve as a blueprint for replication across Europe and beyond. The main goal is to make use of green hydrogen across the entire value chain, while developing replicable business models for wide-scale commercial deployment of H2 across the entire regional energy system. HEAVENN aims to become a Hydrogen Valley blueprint for other regions to replicate.
Cluster I: Chemical Park Delfzijl
- Two H2 pipelines under development in Delfzijl. The first will connect the Delta to the existing infrastructure. The second will connect the (to be built) 20 MW DJEWELS 1 electrolyser to the BioMCN factory and will be prepared for third party connections and extensions for other offtakers. Pipeline material developed in the project is reinforced thermoplastic reducing costs for H2 infrastructure.
- Location to build the water electrolyser has been determined. Optimal option for connection to the HV network was selected.
- Trailer fill facility: location confirmed, safety study conducted, implementation of necessary modifications to the NOU process and pipeline infrastructure started, initial concept design and engineering of the site concluded, discussions on the collaboration between partners on H2 supply-transport-use chain are ongoing.
- H2 ship HRS: two potential filling locations identified together with a methodology how H2 can be made available on the ship. H2 containers will be used for the transfer to the ship.
- FCH Dockside power: equipment specified and heating, cooling and provisional H2 requirements provided.
- H2 Salt barge: design and build contract was signed. Long-term contract for deployment of H2 powered vessel for internal transport of salt on Delfzijl – Rotterdam route was concluded. Design of the ship and configuration of H2-electric propulsion initiated, including a Fluid Dynamics calculation to determine required installed capacity and hull shape.

Cluster II: Storage and Built environment
- Salt cavern: GAS successfully conducted first static tests and demonstrated H2 can be safely stored in salt caverns. Connections specification study completed, covering various options, considering different market situations/developments, and scalability of design, resulting in a plot plan and capacity range definition. Design and site lay-out for next H2 caverns in progress.
- Technical design of H2 distribution system completed. Quantitative risk analysis, market orientation and zoning plan were prepared. In 2021, further work was done on the research, design and preparation of the permit for entire H2 chain.
- FC-based power system at data centre: integration of the FC unit has been designed. Detailed design will follow. For necessary permits consultations took place with Groningen Municipality and Veiligheidsregio Groningen.
- First of five H2 heating boilers installed but had to be taken out of operations because permit was not in place. To receive a permit, operational data of the system was needed, which could not be obtained due to COVID and consequential unavailability of required materials.

Cluster III: Emmen Industry
- In 2020 it was decided to implement an at least 4MW Electrolyser (iso 2MW). Concept design completed. Electrolyser development delayed due to the limited interest in green H2 for industry because of lack of economical feasibility. Conceptual connection studies started and paused in Q2 2021. They will be continued when industrial offtake is secured.
- H2 pipeline between GETEC and GZI: commitment was reached to implement the H2 pipeline alongside the already planned H-cal natural gas pipeline, minimizing social impact and costs. Permitting will be finalised in Q1 2022, then construction can begin. After a comparison of the pros and cons of thermoplastic and steel, steel was selected as the material for this pipeline.
- Detail design, site layout, and permit application for HRS completed. Launching customer secured. Commissioning planned for May 2022.
- H2 for steam generation at GETEC: infrastructure study completed, burner conversion study completed, procurement of subcontracters in preparation. Combustion system of gas turbine modified to process 18 volumes % H2.

Cluster IV: Green Mobility
- Procurement of refuse trucks and municipal fleet vans completed. Delivery delayed due to COVID.
- Procurement of H2 taxis delayed due to COVID.
- 15 of 100 H2 passenger vehicles procured. One is into lease as of November 2021.
- Rental and lease company for H2 trucks established. Discussions with transporters and insurance companies ongoing.
- Procurement of 8-seater H2 public transport vans almost completed. Delivery times are 18-24 months, causing a delay in deployment.
- Location development for the HRSes ongoing, including location analyses, discussions with municipalities and other relevant parties.

Impact Analysis, Business Models, and Replication
- Market and economic studies initiated, establishing analytical framework, technical and economical constraints and barriers, market and economic conditions and scenario analysis.
- Development of business models continued with further definition of methodology and specific business cases, based on feedback from techno-economic assessments.
- General methodology for development of environmental and socioeconomic impact analysis of the project was established and scope and potential cut-off criteria for analyses were preliminarily determined.
- Work on EU replication has started based on previous information and experiences from projects like BIGHIT and the H2Territories Platform (HTP). Intensive literature research completed to find a new approach, resulting in Agent-Based Modelling as the methodology where next HTP Tool will be founded.

Studies Enabling Future H2 Roll Out
- Elaborate study on the scale-up possibilities of H2 production from 100MW to 2GW at ENGIE Eemshaven site.
- Assessments done about feasibility of positioning a 20-50MW electrolyser at GZI Next Emmen plot: resulting H2 costs are not attractive for industrial offtake.
- Gasunie conducted studies interconnecting H2 infrastructure. Appr. 90% of the existing NG grid can be retrofitted for H2.
- Study underway into potential use of salt caverns for large scale H2 storage and whether local or central storage is more beneficial.
- Initial desktop research started for potential of Liquid H2 in Eemshaven/Delfzijl.
- Market export study underway and focussed on neighbouring regions in Germany, the Netherlands and UK. Consideration is being given to potential to import and export H2 from Eemshaven/Delfzijl cluster beyond these immediately regional markets.
- Three H2 mobility studies completed: focused on maritime transport, railway transport, and road trucks.
- Roadmap towards 2050 under development.
As the activities have not reached the deployment phase yet, we cannot yet demonstrate progress beyond the state of the art. Once the applications are in operation and we have collected data on the operation, we can begin to assess that.
