Korall Carbon Capture AB

2024-09-02 11:33 by Fredrika Rylén

Problem
Historical high CO2 emissions already present in the atmosphere.

Solution
Impact & deeptech from Chalmers University of Technology called Direct Air Capture (DAC) where it is possible to collect CO2 directly from the atmosphere.

Potential

Global business and impact.

Bury underground, where it can mineralize in the bedrock and prevent it from returning to the atmosphere.

Transform the captured carbon dioxide into new, greener products.

 

The world urgently needs solutions to manage carbon emissions, and Korall has developed a promising one. Our technology captures carbon dioxide directly from the air, a breakthrough achieved by our research team at Chalmers University. During a coffee break, the team left an experiment unattended. When they returned, they discovered something amazing. The chemicals had captured carbon dioxide from the air at an incredible rate, so the technology’s foundation was born.

The business model is simple and can be likened to a garbage truck for the air. We capture the carbon dioxide, a customer pays for the collection, and then receives a certificate for the amount of carbon dioxide collected. We are currently working to scale up, further develop, and improve this technology to reach the market and make a real difference. With this technology, we aim to actively contribute to lowering our emissions and help the world return to a better state.

Anferra

Anferra AB addresses a significant environmental and economic challenge in the steel industry: the disposal of grinding swarf (slipmull), a complex waste by-product from machining processes. Traditionally, managing this waste is costly and environmentally damaging, particularly as the industry shifts towards less CO2-intensive practices that further limit recycling options.

Our patent-pending hydrometallurgical process offers a solution by efficiently recovering iron from this waste and converting it into high-quality iron chloride, a key chemical used in water treatment. This innovative approach not only recycles iron with a recovery rate of up to 90% but also concentrates valuable alloy metals like nickel and chromium and generates hydrogen.

The benefits are substantial: steel companies can significantly reduce waste management costs and environmental impact while enhancing their recycling rates. Additionally, by producing recycled chemicals for water treatment, our process lessens reliance on raw materials and supports circular economy principles across multiple industries.

Sinonus

Sinonus is a spinout from Chalmers technical university and KTH, and part of  Chalmers Ventures portfolio. The groundbreaking technology of carbon fibers can double as battery electrodes.

The carbon fiber technology in Ccc originates from Oxeon, another of Chalmers Venture’s portfolio companies. The carbon fiber was used in the propeller blades for NASA’s Ingenuity helicopter on Mars, chosen by the engineering team due to their ultralight weight and thinness.

Carbon fiber is a strong and light construction material that can store energy electrochemically. Sinonus uses this multi-functionality to make true carbon fiber-based structural batteries that not only store energy but also become an integral part of the product’s structure. This patented innovation represents a significant step forward in streamlining batteries and how they can be used.

The development of structural batteries at Chalmers University of Technology has proceeded through many years of research, including previous discoveries involving certain types of carbon fiber. According to a study from the same university, the introduction of carbon fiber-based structural batteries could increase the driving range for lightweight EVs by 70 percent. In addition, the lower energy density of structural batteries would make them safer than standard batteries, especially as they would also not contain any volatile substances.

Iloomina

Iloomina is a prototyping house, providing photonic integrated circuits based on SiN with a record-low loss and high design flexibility. As such, it facilitates development of future solutions in the sectors such as telecommunications, optical sensing, quantum applications. The goal of Iloomina is to become a provider of microcombs — a novel laser source that provides multiple wavelengths. Built in the SiN platform, Iloomina’s microcomb technology is power-efficient, scalable and mass manufacturable. As such it can have tremendous impact on mass-market applications such as datacenter interconnects, replacing the current technology with much needed improvement of energy-efficiency and scalability in data-rates.

Braviz

The journey toward Digital transformation in Industries is creating a very fragmented data ecosystem. Engineers need to make decisions based on data, but the problem is that there is a lot of data, which is either not accessible or is often presented in a way that is difficult to understand. This makes data-driven operations and decision-making inefficient and unscalable.

Braviz streamlines industrial intelligence, making it more accessible and consumable for engineers. The platform serves as a hub for aggregating data and fostering ad-hoc analysis. It unifies the platform with engineer-driven analysis, and AI-assisted analytics, and seamlessly integrates with external AI models.

Our goal is to make it effortless for engineers to access the data they need for decision-making. By giving them the help of a virtual data scientist that can easily dig out insights, we make sure that engineers can focus on what they’re really good at, which makes decision-making smoother and more efficient.

Repli5

Repli5 speeds up and lowers the cost of developing autonomous vehicles. Through synthetic training data in virtual worlds, the company offers software where vehicles learn to act faster in traffic. The potential for synthetic training data is also great in other industries.

Adsorbi

Air pollutant capture is essential for avoiding health problems and protecting sensitive objects. But today’s unsustainable material use has severe environmental impacts and manufacturers looking for new materials for air pollutant removal have few alternatives. We want to help industries in sustainable transition by providing an innovative super-material.

Adsorbi has developed an adsorbent material that is highly efficient in capturing air pollutants, 5-8 times more effective than the existing alternatives on the market. The material is cellulose-based and designed to have a low environmental impact throughout the entire value chain.

Air pollutant control is needed in many markets and the first Adsorbi products are launched for art conservation. Museums and archives need solutions that remove air pollutants in storage spaces, are made from stable materials, and are easy to use. Adsorbi has developed storage pads together with art conservators which will be launched in 2023.

Mat4Green Tech

Indium plays a key role in the production of flat screens, touch screens and solar cells. The demand for the metal is great but the supply is today very limited all over the world. Mat4Green Tech has developed a technology that recycles Indium from industrial waste in an efficient and climate-neutral way. The technology for recycling and producing Indium has no CO₂ emissions, which is completely unique. At the same time, we recycle more efficiently and with a higher recycling rate than competitors can do today. Right now we are recycling on a small scale in a test environment and the next step is to scale up production.

SINOM

The climate crisis puts more and more pressure on building owners to renovate their buildings to reduce energy demand and carbon emissions. At the same time, the European building stock is relatively old and in need of extensive renovation measures. In Sweden alone more than half of the 2.4 million apartment units were built before 1980, out of which more than 300 000 apartments are in urgent need of renovation. This growing backlog of renovation needs together with limited resources and manual and short-term planning processes makes it difficult for building owners to address these issues.

SINOM is a digital and smart alternative to the manual and traditional ways of maintenance and renovation planning. SINOM´s web-based planning tool builds on a unique algorithm to enable fast, optimized and data-driven maintenance and renovation planning for buildings and building portfolios. Using the SINOM webtool, building owners can map their renovation needs and quickly and easily generate maintenance and renovation plans that are optimized and prioritized based on a life-cycle perspective which saves costs, time and reduces the energy and climate impact of their buildings!
