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.


Ambidex’s innovative software solution makes it possible for supermarkets to transform their refrigeration systems from an untapped resource into a new revenue stream, by using them as balancing services for the national electrical grid.

By using supermarket refrigeration systems to balance and stabilize the national electrical grid we pave way for the usage of renewable energy sources, such as wind and solar, which have a less predictable power output and need the stability.


Valys sensors streamline water purification

The technology behind the company is based on fluorescence spectroscopy research by Professor Kathleen Murphy at Chalmers. The founding team also includes business developers Andrej Krsteski and Sari Alsibai, who have backgrounds in economics, production development, and Chalmers Entrepreneurship School.

Today, water treatment plants use an excessive amount of chemicals unnecessarily. Additionally, activated carbon filters are not utilized to their full capacity. Valys aims to change that with technology built on 20 years of research at Chalmers.


Traditional control of heating systems for residential buildings relies on simple feed forward controllers that only consider the current outdoor temperature when deciding the level of the output from the heating systems. Algeno provides cloud based algorithms and services that combine AI and model predictive control (MPC) to better control the systems and reduce the energy consumption of the buildings.
The technology was developed in collaboration with Fraunhofer-Chalmers Center (FCC), Örebrobostäder, Chalmers and Energimyndigheten and is currently implemented in over 300 heating system centrals all around Sweden.

Endre technologies

To reach climate targets we need to transform our energy system to be carbon neutral. This will require significant investments in the electric power grids that makes this transformation possible. To build an efficient electric power grid, knowing when, and where new electricity demand will be, and how it will behave is crucial. By collecting large amount of data from many different sources, endre developed a technology to build a virtual electricity future. In this virtual electricity world, users can analyze and investigate the technical and financial impact of scenarios and decisions. Through the use of endres platform, we reduce uncertainty of the future, saving both time and resources for grid operators.


The world is looking to replace the 84% fossil energy currently used on earth with sustainable options to make a minimal impact on the planet’s ecology. Hydrogen is the most promising candidate as an energy carrier and raw material to arrive to net zero carbon and beyond as soon as viable.

Smena has developed a unique and patented material that can be potentially make hydrogen cheaper to produce and safer to work with. Our material can also potentially be used to better monitor poisonous gasses such as Nitrogen Dioxide (NO2) and ammonia, (NH3). Smena’s technology stems from world class research in physics at Chalmers University of Technology.

Minesto Logo chalmers ventures


Minesto develops a revolutionary concept for generating electricity from the ocean that unlocks a so far untapped renewable energy resource.


Enairon is developing a system for largescale, cost efficient energy storage. If one can efficiently store energy, one can utilize energy from varying renewable energy sources such as sun and wind and phase out fossil energy. The technology is based on a new principle for compressing air which creates unique opportunities for high efficiency. The technology is patented and has already been successful in a series of prototype tests.



We live in an unsustainable world, where large amounts of drinkable water are used in our daily tasks. For example, one single laundry consumes 60 litres of fresh water. Laundry also consumes energy and releases microplastics. Mimbly’s first answer is the Mimbox, a device that lowers the water and energy consumption of laundry machines while stopping microplastics. By recycling laundry water, Mimbly’s customers can preserve the environment and save money in the same time, effortlessly.
