Supercapacitor energy storage design for electric oil drilling rigs

How does a supercapacitor work?

Employing the supercapacitor, an automatic energy storage system is designed. A supercapacitor stores and releases energy through a process of ion absorption and release at the electrode-electrolyte interface. The control strategy of this system is discussed.

Can electric energy storage systems be used for drilling rigs?

The work to develop electric energy storage systems for drilling rigs has been underway worldwide for the last 5 years, however, mainly targeting isolated offshore rigs.

Is supercapacitor an energy storage device?

In this study, supercapacitor as an energy storage device will be examined for current status and future perspective. Trade distribution of supercapacitor as an energy storage device and taken patents will be evaluated. 1. INTRODUCTION Fossil fuels are the main energy sources that have been consumed continually.

Which rigs have energy storage systems for onshore drilling?

The energy storage system developed for onshore drilling is among the world’s first ones. As a foreign analog, only the project of the German rig manufacturer Bentec implemented in Oman can be highlighted. In 2017, the container-type 0.9 MW Bentec ESS with a storage capacity of 0.3 MW was put into trial operation on the KCA Deuteg T-94 rig.

How to reduce the cost of oil drilling rig lifting system?

An effective approach to reduce the cost of an oil drilling rig lifting system is recycling the energy during the process of lowering drill string and casing. In the present work, for a multi-model drilling rig, the total energy recovery and energy-saving ratio are calculated with considering the effect of hook without loading.

Can a hybrid energy accumulation system be integrated into a rig power circuit?

The efficiency of using a hybrid energy accumulation design is proven; the design calls for joint use of Li-ion cells and supercapacitors, as well as three-level inverters, to control the storage system. The article reviews all possible options for connecting the system into a unified rig power circuit, and the optimum solution is substantiated.
