When it was discovered that graphene, a type of carbon, could be extracted from graphite, enthusiasts believed that this would transform the world
According to Terry Tanaka, they might have been early rather than incorrect.
In 1874, Scottish-American businessman Andrew Carnegie finished building the mile-long Eads Bridge, which crossed the Mississippi River into St. This is Louis. Nobody thought steel was sturdy enough for a project like this at the time. According to Vivek Koncherry, CEO of Graphene Innovations Manchester, Carnegie demonstrated its strength by having an elephant walk alongside it. As a result, Carnegie made sure that mass-produced steel would "lead to the rise of the skyscrapers" and serve as the foundation of the subsequent industrial revolution.
According to Koncherry, graphenea sheet strong enough to support an elephant standing on a pencilis poised to change the modern world in the same way that steel did in the past. It could be profitable for investors in addition to being a prime example of innovative British science. According to Koncherry, "some of the biggest companies of the future" will emerge thanks to graphene and related nanomaterials.
Graphene: Where did it originate?
According to James Baker, CEO of Graphene@Manchester, the history of graphene started in 2004 with two scientists, Professors Andre Geim and Konstantin Novoselov of the University of Manchester, some graphite, and some sticky tape. They discovered that they could separate a single two-dimensional atomic layer of carbon from the graphite using a modified sticky tape. Graphene is a naturally occurring, albeit extremely rare, material that is a crystallized single layer of carbon atoms arranged in a flat honeycomb or hexagonal lattice pattern. It can function as a membrane that lets some molecules pass through while blocking others, and it is stronger than steel and more conductive than copper, among other "unique properties."
According to Baker, the most intriguing applications of the material happen when you "add it to things to complement them" and enhance their functionality. It has already been shown by scientists to be a valuable addition to materials used in batteries, energy storage, water filtration, hydrogen storage, corrosion-prevention coatings for metals, membranes, water desalination, and even wearable technology inks. According to Baker, Manchester researchers have already created graphene sensors that have been implanted into patients' brains, suggesting that the substance may even be used to treat diseases like Parkinson's and strokes.
According to Asad Farid, portfolio manager of JSS Sustainable Equity Strategic Materials at J, graphene's "exceptional qualities" are that it is "lightweight, while having high tensile strength and electrical conductivity" and "enhances the performance and durability of products."

Its "simplicity"graphene "is not a new compound and doesn't use any exotic materials in its manufacturing" and can be extracted from graphite, a common substanceis another characteristic that sets it apart.

The challenge of living up to expectations.
Forecasts that the world was going to change due to the discovery of graphene turned out to be too optimistic. However, Baker contends that this had nothing to do with the content itself and was instead the result of irrational expectations. Geim and Novoselov's discovery in 2004, their Nobel Prize award in 2010, and the lack of commercial applications until the present day are not particularly uncommon. After all, it took 25 years for the first carbon-fibre products to reach the market, and those were high-end, luxury goods like golf clubs, tennis rackets, and Formula One cars. In actuality, it typically takes ten years for new materials to enter the market, and it takes even longer for them to reach a mass market. Graphene is therefore still considered a "relatively young material."
According to Aneeka Gupta, director of macroeconomic research at WisdomTree, production costs, scalability issues, and a lack of standardization are the main obstacles preventing widespread adoption. Graphene does not yet meet industry standards for affordability, consistency, and scalability. In fact, "there werent even any widely adopted standards" for the content until quite recently. Large industrial companies care about this because they won't want to redesign a process around a material unless they are certain that other suppliers will be able to produce comparable materials.
The good news is that all three issues have been addressed, albeit in a "very quiet incremental way," despite these "headwinds," according to Gupta. Graphene is beginning to establish itself in "niche, high-value components" but hasn't quite reached the stage where it is used extensively throughout industry. The Advanced Carbons Council trade association's Terrance Barkan is more optimistic, pointing out that many businesses have been experimenting with adding graphene to their products for the past five years and are now prepared to begin launching them.
Establishing international standards.
The graphene classification framework, which is now an ISO standard and a global benchmark for uniformity across industries, was developed by the Advanced Carbons Council, which has been at the forefront of efforts to establish product quality standards. Additionally, the council works to assist businesses in auditing and inspecting the graphene supplies they utilize. Barkan emphasizes the significance of this. "The credibility of the entire market is harmed if a company uses a substance that they are told is graphene but isn't, and it doesn't function as they anticipated. The "
The main issue of producing graphene on a large scale at a low cost has also been resolved. According to Kjirstin Breure, CEO of HydroGraph, the method has historically involved "exfoliating graphite," which is essentially the same strategy Geim and Novoselov employed back in 2004. Based on research conducted at Kansas State University, her company has created a different method that uses hydrocarbon gas explosions.
Although this method may not be the most cost-effective in terms of weight, "it works out as much cheaper for our customers as they have to use much less of it" because the end product is of such high quality when compared to other approaches. As HydroGraph begins to relocate its operations to a large-scale production facility in Houston, Texas, which Breure estimates will be able to produce hundreds of metric tonnes of graphene annually, costs are expected to drop even more. As demand soars, she anticipates that production will increase even more.
There are other companies spearheading a revolution in the production of graphene besides HydroGraph. Concretene CEO Mike Harrison cites the efforts of Levidian Nanosystems, a University of Cambridge spinout that has developed its own method for producing superior graphene from methane. Harrison shares Breure's belief that we have reached a point where more businesses will be interested in using the material due to cost reductions and quality improvements. This will allow those producing graphene to take advantage of economies of scale, which will further lower the price.
Construction with graphene.
The A4 Turin-Milan motorway features a novel asphalt made of hard plastic and graphene.
The construction sector is one that is beginning to enthusiastically adopt graphene. For instance, Concretene claims that adding graphene to concrete (also known as "graphene doping") improves the material's performance by 10% to 20%. As a result, building firms can lessen the quantity of cement they must use in their concrete, which lessens the environmental effect of their projects. Cement consumption can be reduced by 79 kg for every 50g of graphene added.
Currently, the majority of Concretenes' clients, such as United Utilities, are businesses interested in the product because it will improve their green credentials. The Middle East has been interested as well. However, Harrison believes that graphene in concrete will be the best option in a few years, both economically and environmentally.
Additionally, graphene is expected to play a significant role in other areas of the building industry. For instance, Vector Labs' Nathan Feddy and Liam Britnell are already collaborating with a variety of partners, including major builders, to launch a line of products that use graphene to enhance home insulation. Noting that graphene-enhanced materials "can reduce the spread of flames in the event of fire by up to 80 percent, without impacting on the performance of the original material, which is one of the weaknesses of existing materials," they are especially impressed by graphene's potential to lower fire risks.
A growing graphene market.
The graphene revolution may be leading the way in the construction industry, but other industries are following closely. Although there isn't a "single killer application" at the moment, Barkan lists at least 45 distinct vertical markets where graphene will be crucial. For instance, graphene is already being used in the paint and coating industries to prevent corrosion. The material is also being embraced by the textile industry; "more than a dozen companies now make graphene-enhanced clothes." Graphene is beginning to be used "to make smaller and more efficient semiconductors, for use in a wide range of electronics and batteries," according to Koncherry. According to Gupta, recent reports indicate that graphene-based photonic chips made by Cambridge Graphics can "deliver not only much higher data throughput, but also 80 percent lower energy use than equivalent silicon chips". Given that "they are exactly the kind of niche, high-value market where graphenes speed and optical properties matter more than its lack of scale," this could have significant ramifications for telecom companies and AI data centers.
In summary, hundreds of graphene-related businesses have emerged globally. According to Gupta, "the hype that we saw a few years ago has died down, a slightly slower, but more realistic, revolution has taken its place," with graphene being used to enhance batteries, coatings, plastics, concrete, and filters. Ivan Buckley, director of business development at Graphene@Manchester, notes that the global market for graphene is "estimated to grow by around 27 percent a year over the next decade to 2036" according to research from IDTechEx.
A thrilling period for materials.
The fact that businesses and researchers are "developing a whole family of other 2D materials" in response to graphene's success is perhaps the most obvious indication of change in the materials industry, according to Baker. He believes that the MXenes, a family of 2D materials based on metals, will be a topic of much greater discussion in the future. They are occasionally used in conjunction with graphene and have a "potentially huge" range of applications for energy storage and aircraft.
According to Drexel University's Yury Gogotsi, MXenes also outperform all other materials in specific characteristics that make them perfect for use in wearable electronics and insulation. Although MXenes have historically been "in the shadow of graphene," interest in them is growing, particularly in Asia. There are currently "more than a dozen" Chinese companies that manufacture and market MXenes, in addition to those in the US, Korea, and Europe. Businesses like Murata and Samsung possess "dozens of patents" in this field.
Gii is another promising material that resembles graphene. Gii, which was discovered in 2014 and emerged from graphene research, shares many characteristics with graphene. However, according to Marco Caffio, co-founder and chief scientific officer of iGii (formerly Integrated Graphene), Gii "can be grown in three dimensions, without losing performance," whereas the former takes the form of a single 2D layer. According to Jean-Christophe Granier, CEO of iGiis, it can also be produced "anywhere where theres electricity" and at a low cost. The development of "faster, more accessible ways to detect disease or water contaminants, as well as the creation of flexible printed batteries the size of a fingernail" is one area in which Granier and Caffio note that industry has already shown a great deal of interest. Granier and Caffio's assessment of the current state of the materials industry as "exciting" is not surprising given these developments.
How to purchase graphene.
In graphene, there is no safe route.
The graphene theme is not offered by any exchange-traded fund (ETF) or other collective investment. Additionally, the local businesses must be regarded as high-risk. According to Terrance Barkan of the Advanced Carbons Council, investors have grown impatient with some of the very early public companies that have struggled to reach commercial sales, and as a result, their stock prices have declined. However, since "sales cure all ills," businesses that are successful in reaching both profitability and critical mass may see a return in investor interest.
A trigger for broader acceptance.
HydroGraph Clean Power (Vancouver: HG) is one business that is currently witnessing a sharp increase in revenue. A technique for removing graphene from gases has been developed by the company. According to CEO Kjirstin Breure, "we alone could serve as a sort of catalyst for wider adoption of graphene by industry" because the company is currently constructing a large production facility in Texas that could significantly reduce costs and increase output. In fact, HydroGraph is so optimistic about the future that it intends to transfer its US share listing to the Nasdaq.
Better cement and batteries.
WisdomTree's director of macroeconomic research, Aneeka Gupta, is upbeat about the future of the Canadian company Graphene Manufacturing Group (Toronto: GMG), which produces batteries based on graphene. The company and Rio Tinto, a mining company, partnered two years ago to create a battery that uses graphene to increase battery safety and lower cooling requirements. When batteries need to be charged and discharged fast, this is helpful in harsh environments. Gupta is especially enthusiastic about GMG's graphene spray products, which can be used to increase metals' conductivity without sacrificing functionality.
According to Gupta, the Australian company First Graphene (Sydney: FGR) is beginning to release products, and its graphene-enhanced cement has progressed from trial to mass production. Major construction companies like Morgan Sindall and Breeden are starting to award contracts to the company. In fact, First Graphene announced earlier this month that 600 tonnes of graphene-enhanced cement would be produced at the Breedon Group facilities in Derbyshire for use in upcoming UK projects.
Two other plays.
Businesses that provide equipment to manufacturers are a slightly different way to participate in the graphene revolution and the development of related materials. For instance, CVD Equipment Corporation (Nasdaq: CVV) manufactures systems for growing 2D materials like graphene. Even though its revenue is increasing by about 7% annually, it still trades at a discount to its net assets of about 18%.
The London-listed microcap Directa Plus (Aim: DCTA) may be of interest to those who are particularly daring with risk. Graphene nanoplatelet-based products are manufactured and supplied by the company. Filters and textiles, including sneakers, use these. It is not currently profitable, like all of the aforementioned businesses, but revenue is anticipated to increase by more than 50% this year compared to 2024 and then quadruple once more in 2026.
