Successful workshop: Potential of water electrolysis for large-scale energy storage

Potential of water electrolysis for large-scale energy storage.

PrometH2 held this November 16th a face-to-face workshop in Madrid within the IMPACT HUB space, a unique space opened only for the celebration of sustainable events. The event was attended by a total of 100 guests (online and face-to-face).

The main objective of the PROMET-H2 project is to develop a polymer technology electrolyser – one of the most suitable for coupling this process to the production of renewable methanol – reducing its current cost and making it more sustainable and reliable. This means developing its main elements, including the pressurized proton exchange membrane water electrolyser (PEMWE), at a lower capital cost than that achieved to date – between 500 and 700 euros per kilowatt (kW) – without compromising its performance and durability, and replacing noble metals with others that are more benign from an environmental and economic point of view.

The following speakers participated in the workshop:

Daniel García-Sánchez, Senior Researcher at the German Aerospace Center (DLR) and Coordinator of Promet-H2, who spoke about “The European project PROMET-H2: Cost- effective proton Exchange Membrane water Electrolyser for Efficient and Sustainable Power-to-H2 Technology” and presented the progress of the PROMET-H2 project in reducing costs and environmental impact for the fabrication of a PEM electrolyzer by reducing critical materials.

Stefania Siracusano Senior Researcher Consiglio Nazionale delle Ricerche, who spoke about “PEM electrolysis for power to gas and grid balance service” will present how #hydrogen represents a successful method of storing excess energy from oversupply and how it can be stored indefinitely without loss of the energy it contains.

Also, Vanesa Gil Hernandez – Senior researcher from the Aragonese Foundation for Research and Development (ARAID) and Head of the R&D Department at Aragon Hydrogen Foundation (FHa), focused on “Low temperature water electrolysis: Features & Capabilities.” Considering the role of water electrolysis in a decarbonised energy market. Opportunities in on-grid and off-grid. Key Challenges at R&D level in providing grid balancing and at demo level linked to photovoltaic.

Another expert was Wim Béatse – Application Development Engineer for the fuel cell and water electrolysis applications. – at The Chemours Company, who spoke about “advanced Membranes for Improved Water Electrolyzer Performance”.

Patricia Rabanal Hernández Head of Engineering Department at H2Greem Global Solutions was part or the event and spoke about “H2Greem: Manufacture of PEM electrolysers”.

Maribel Rodríguez Olmo Sr. Business Development Manager at Repsol, focused on “How far is hydrogen needed in the energy matrix? Repsol’s decarbonization roadmap”.

To continue, Carlos Navas Head of Strategy and Regulatory Affairs Enagás Enagás Renovable presented Green Hysland – Deployment of a H2 Ecosystem on the Island of Mallorca.

SebastianKönig Director Sales Electrolysis at Air Liquide focused his presentation on “Large scale water electrolysis as front-end for integrated PtX-plants” and highlighted how PtX is the process of converting renewable electricity into a wide variety (X) of end products, using hydrogen for that purpose.

Rodrigo Pérez Gil from ARIEMA Energía y Medioambiente spoke about the “Development of a new alkaline electrolyser associated to a renewable offshore plant” and highlighted the development and scale-up of a multi-megawatt alkaline electrolyser to operate in an offshore environment.
