OVERVIEW - DePLAN : EARTH - TEMPLATE

Grid-scale electric storage units are devices that can store large amounts of electricity generated from renewable sources such as wind and solar, and release it when needed to balance the grid demand and supply. There are many types of grid-scale electric storage units, such as batteries, flow cells, pumped hydro, compressed air, thermal, and hydrogen 1.

According to a recent report by the US Department of Energy 1, the most cost-effective and environmentally safe type of grid-scale electric storage unit depends on the application and the duration of storage. For example, for short-duration applications (less than 4 hours), lithium iron phosphate batteries, a subset of lithium-ion batteries, are still the preferred choice based on cost and energy density considerations 2. For long-duration applications (more than 4 hours), hybrid flow batteries or regenerative fuel cells are promising technologies that can store electricity for very long durations for about a fifth the price of current storage technologies, with minimal location restraints and zero emissions 3. These technologies combine carbon-based electrodes with economically sourced electrolytes, such as manganese or sulphur, and use nitrogen-doped graphene to enhance the electrode durability and performance 3.

GRAPHENE : IDENTITY & RESOURCE SITES

Graphene is a two-dimensional form of crystalline carbon, either a single layer of carbon atoms forming a honeycomb (hexagonal) lattice or several coupled layers of this honeycomb structure 1. Graphene has many remarkable properties, such as high strength, electrical conductivity, transparency, and flexibility 2.

The Earth’s primary resources are the natural materials that are essential for life and human activities. They include air, water, soil, minerals, fuels, plants, and animals. Some of these resources are renewable, meaning they can be replenished by natural processes, such as sunlight, wind, and water. Others are non-renewable, meaning they exist in finite amounts and take a long time to form, such as coal, petroleum, and metals. The location and distribution of these resources depend on various factors, such as geology, climate, ecology, and human activity 3 4.

Some of the main topics related to graphene are:

Structure and properties: Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, forming a two-dimensional material with exceptional mechanical, electrical, and thermal properties. Graphene is the thinnest, strongest, and most conductive material ever measured. Graphene also has unique optical, magnetic, and quantum phenomena ¹ ²
Synthesis and characterization: Graphene can be produced by various methods, such as exfoliation from graphite, chemical vapor deposition, epitaxial growth, and chemical synthesis. Graphene can be characterized by various techniques, such as scanning probe microscopy, electron microscopy, spectroscopy, and transport measurements ³ ⁴
Applications and challenges: Graphene has potential applications in various fields, such as electronics, energy storage, biomedicine, sensors, composites, and coatings. Graphene also faces some challenges, such as scalability, integration, functionalization, and environmental impact ⁵

Current Major Producers Of Graphene-Based Electric Storage Batteries Are :

According to a market report by Fortune Business Insights, some of the major companies in the graphene battery market are Samsung Electronics, Huawei, Log 9 Materials, Cabot Corporation, Graphenano, Nanotech Energy, NANOTEK INSTRUMENTS, INC, XG Sciences, ZEN Graphene Solutions Ltd., GrapheneCA, Global Graphene Group, Vorbeck, Graphenea, Hybrid Kinetic Group Ltd., and Targray 1. However, the report does not specify which of these companies are the largest producers of graphene-based electric storage batteries on a grid-scale basis.

A possible way to measure the size of the producers is by their revenues from the grid-scale battery segment. According to Statista, ABB was the largest grid-scale battery manufacturer in the world in terms of revenue in 2020, generating over 234 million U.S. dollars from sales in this segment. Samsung SDI ranked second with a revenue of nearly 160 million U.S. dollars in the grid-scale battery energy storage segment 2. However, these figures do not indicate whether the batteries were graphene-based or not.

Another possible way to measure the size of the producers is by their installed capacity of grid-scale battery projects. According to MIT Technology Review, Oregon-based ESS and Massachusetts-based Form Energy are two of the leading companies in developing long-lasting grid batteries that can store energy for between four and 100 hours, respectively. These batteries could enable higher integration of renewable energy sources and provide grid stability and resilience 3. However, these companies do not disclose whether their batteries use graphene or not.

Therefore, it is difficult to answer your question with certainty, as there is no clear and reliable data on the current largest producers of graphene-based electric storage batteries on a grid-scale basis. However, based on the available information, some of the potential candidates are Samsung Electronics, Huawei, Log 9 Materials, Cabot Corporation, Graphenano, Nanotech Energy, NANOTEK INSTRUMENTS, INC, XG Sciences, ZEN Graphene Solutions Ltd., GrapheneCA, Global Graphene Group, Vorbeck, Graphenea, Hybrid Kinetic Group Ltd., Targray, ABB, Samsung SDI, ESS, and Form Energy.
