Technology

In order to help the Energy Transition by improving the Energy Storage systems for enhancing the grid and allowing more renewable penetration, HESStec has developed several enabling technologies.

 Hybridization

The pain point of the batteries performance under “power profiles”, which creates uncertainties about operation and degradation, is currently approached through oversizing a BESS solution (only battery system), leading to additional costs (in CAPEX and OPEX) in an expensive technology beforehand (commonly Li-Ion) and eliminating the profitability of the BESS solution.

However, HESStec approaches this challenge by adding Ultra Capacitors or any other available energy storage system hybridizing the system.

Optimization

Some algorithms are focused towards the optimization of the operation of hybrid systems, harnessing the potential of each one regarding its technical and economical characteristics.

Optimization is one of our own expertise, not only for the hybridization but for optimal sizing of Energy Storage Systems depending on the different services to be provided.

Control

HESStec has developed its own control platform for Ultra-Capacitor Technologies to be capable to control and operate at grid scale. Thanks to the previous technologies, HESStec has developed different control layers for providing advanced functionalities for the grid, allowing the substitution of synchronous generators by Virtual Synchronous machines.

Additionally, HESStec has developed the State of Function Concept to manage distributed energy resources as a network, addressing the technical challenges related to information management, system dynamics, and communication latencies.

VisynC
This project seeks to develop and validate a hybrid storage system, which combines lithium-ion batteries and ultracapacitors, with management through a specific control system. It will be connected to the Lanzarote-Fuerteventura electrical grid, operating in synchronous grid-forming mode, with a power of 16 MW and 3.45 MWh of storage capacity.

HL-Powertrain project
HL-POWERTRAIN is a collaborative project funded by the European Union through the Operational Programme of the European Regional Development Fund (FEDER) of the Valencia Region 2014-2020. This project, led by the Valencian Agency of Innovation (AVI), focuses on the technological and innovative development of the propulsion system for hyperloop using a turbojet engine and an electric vehicle powertrain.
Proyecto HYBRIS: Innovación en Almacenamiento de Energía para un Futuro Sostenible
HYBRIS project
The HYBRIS project, financed by the EU and part of the “Hybridisation of battery systems for stationary energy storage H2020-LC-BAT-9” call, of the Horizon 2020 Research and Innovation Framework Programme, aims to optimise systems as highly efficient, economic and sustainable hybrid solutions in micro-network applications.
