Energy Storage | Hamad Bin Khalifa University

The purpose of the Energy Storage portfolio is to develop safe, reliable, and cost-effective large battery technology that enables the storage of surplus energy and the integration of renewables, in particular solar, with grid. It aims to address technical barriers (scientific and engineering) in battery technologies to enable their adaptation for solar energy applications;  the objectives also include the development and deployment of battery field demonstrations to assist in testing, validation and benchmarking of battery technologies that can meet solar technology needs. Energy storage portfolio also aims to explore emerging energy storage technologies to identify opportunities and develop innovative solutions (discover/invent materials, processes, systems and intellectual property).

SUMMARY OF RESEARCH ACTIVITIES

  • Supervisory control and data acquisition (SCADA) system was developed for Solar Test Facility battery for efficient operating conditions of the large 500kWh/250kW li-ion battery.
  • Lithium-Sulfer (Li/S) battery with a specific capacity of 880 mAh/g was developed. This could add value to sulfur (side product of gas industry).
  • New cathode materials for sodium battery application based on affordable phosphates, sulphate and vanadate materials were deigned and synthesized.
  • Technical evaluation of energy storages systems based on performance/merit taking into consideration Qatar climate/gap/opportunity. 
  • Modified Carbon Nano Tubes (CNTs) and /or Carbon Nano Fibers (CNFs) were prepared and tested for hundreds of cycles with improvement in electrochemical performance for flow battery application.

 

Lithium Ion Battery

Pillar aims to develop advanced lithium ion batteries that will meet the requirements of the PV application in terms of stability, affordability and safety, hence integrating electrochemical energy storage systems with PV for the off-and on-grid applications.

Emerging Technologies (Beyond Lithium Ion batteries)

Pillar is focused on developing battery systems that outperform the current technologies (Sulfur) and/or drastically decrease their cost (sulfur and sodium), in order to enhance sustainability and cost-effectiveness.

Flow Redox Batteries Pillar

Aims to develop high performance and cheaper battery materials and designs in order to make flow batteries economically viable for mass market and be deployed in a number of remote locations (e.g., livestock farms) in Qatar.

PARTNERSHIPS & COLLABORATIONS

Venegrate

QEERI has developed close contacts with Qatar Solar Technologies (QSTec) in order to identify research topics of common interest. QEERI plans to use silicon produced by QSTec to design and fabricate wafers and cells of high performance.

École Polytechnique Fédérale de Lausanne (EPFL), Switzerland

QEERI and EPFL (Switzerland) established a strong partnership to design and produce silicon solar cells that perform better in desert environments and to develop the emerging Perovskite-based PV technology.
