Project Timeline

7,000 hours of operation reached

Since June 2017, the RSOC system was operated for more than 7,000 hours. Over the course of operation, two long-term steady state operation phases in natural gas fuel cell mode and electrolysis mode were accomplished, each about 1,500 hours long. Hardware and software upgrades were implemented during commissioning and in between operation regimes to increase system reliability.
The NG-FC operation proofed the reversibility of the system and showed its ability to produce power at efficiencies over 50 %LHV. Also first results on shut-down, start-up and switch-over times were gathered. The electrolysis operation demonstrated for the first time the possibility to integrate a high temperature electrolysis as hydrogen supplier into an existing industrial site. The RSOC unit also showed high efficiencies of close to 80 %LHV. With one third of the produced hydrogen fed in the hydrogen pipeline, for the first time hydrogen from a high temperature electrolyser has been used in an industrial application.

Mid-Term Review @ FCH JU

After the successful submission of the first Periodic Report GrInHy is going to take the next step. On Tuesday, 21 November, the project’s progress is being audited by the Fuel Cell and Hydrogen Joint Undertaking at the Mid-Term Review (MTR) in Brussels. At the MTR the project team will present the first results to the Project Officers and external reviewers to jointly discuss the next steps to take.

System operation in industrial environtment started

This September, GrInHy's long-term test operation started at Salzgitter Flachstahl GmbH with the fuel cell operation with natural gas (SOFC–NG, Solid Oxide Fuel Cell). Thus, the operation started four months before the schedule.

3rd Project Meeting

From August 30 - 31 the project team has been guest at VTT in Espoo, Finland. After the meetings in Madrid (BR&T-E), Dresden (sunfire) and Salzgitter (SZMF/SZFG), the 3rd project meeting at VTT was the first at one of the research organizations.
Besides the obligatory lab tour through VTT's hydrogen and catalyst activities, main focus was on the progress of the first 18 project months and the upcoming 1st periodic reporting.

GrInHy's first public appearance

As part of the conference “Efficient and emission-free - expansion of hydrogen and fuel cell applications” the GrInHy system was available to interested participants.

The conference was held at the Hotel am See in Salzgitter on June 7 and was attended by almost 200 attendees from politics, administrative bodies, research organizations and associations.

Some presentations and further information can be found here.

Everything comes together

On Monday, 2017/05/29, the installation of both the RSOC and HPU container started at Salzgitter Flachstahl GmbH. Whereas sunfire’s container consists of almost 1,500 reversible Solid Oxide Cells, Boeing’s container with its pressure swing adsorption and compressor is responsible for the purity of hydrogen at 10 bar(g).

GrInHy at Hannover Messe 2017

The GrInHy project was presented at this year's Hannover Messe (Hanover Fair). One of the central elements at the booth of Salzgitter AG was a model that explained the basic principle of the GrInHy project and its implementation at the integrated iron-and-steel works of Salzgitter Flachstahl.

Together with an accompanying presentation, the GrInHy project was presented to experts of both the steel and hydrogen industry, to national and international politicians and to a broader audience.

Furthermore, we used the fair for a productive Project Coordination Meeting. Beside other things, the next steps regarding the operation of the reversible high-temperature electrolyzer were discussed between Sunfire, Salzgitter Mannesmann Forschung and Salzgitter Flachstahl.

System fabrication almost finalized

Sunfire finalized the first of two Hotboxes for the RSOC prototype. Each Hotbox contains 3 ICMs à 720 Solid Oxide Cells and all high temperature components to operate them (e.g. heat exchangers, after burner and reformers). In parallel, the second Hotbox, Coldbox (fluid supplies) and the container (housing, power electronics and BoP) are implemented and close the finalization.

If everything stays on schedule, the commissioning of the GrInHy system - including Boeing's Hydrogen Processing Unit - will start by the end of May 2017 at Salzgitter Flachstahl.

2nd Project Meeting

From 28th - 29th of March, Boeing Research and Technology Europe (BR&T-E) invited us to the 2nd Project Meeting in Madrid, Spain.

Besides other things, BR&T-E is responsible for designing, assembling and commissioning of the Hydrogen Processing Unit (HPU) in order to provide hydrogen of highest purity (99.999 %) to Salzgitter Flachstahl (SZFG).

During the period of the Project Meeting each Partner informed the consortium about their progress of work. One main outcome was the commitment of sunfire, BR&T-E and SZFG to start operating the GrInHy System in Salzgitter by July this year. This means, we are about six months ahead schedule with regard to the system operation.

In the end of meeting we still had time to have a look at the current state of the HPU (s. picture). Great work and thanks to everyone!

System layout frozen

Milestone 1,

GrInHy reaches the first milestone on-time.
Based on preliminary techno-economic data and operation profiles most promising business cases and their requirements were identified. Adapted to those needs, Sunfire developed several system layouts. Each of them has been evaluated by steady-state system simulations.

The layout with the best prospect has been chosen and already integrated into the 3D design of the rSOC system (see attached picture).
