Vyse Tech AB

Vyse Tech develops a groundbreaking technology that transforms how we use hot water. Today, huge amounts of energy and water are wasted because hot water is heated centrally, stored in large tanks, and pushed through long pipes before reaching the user. The result is standby losses, pipe losses, and unnecessary flushing – inefficiencies that cost households, property owners, and society at large.

The innovation is a faucet-integrated water heater that produces hot water instantly at the outlet – only and precisely when needed. At its core lies a compact heat exchanger manufactured with advanced metal 3D printing. This patented design enables optimized internal geometry, allowing rapid and highly energy-efficient heating. The product is ultra-compact, easy to install in both new and existing systems, and eliminates virtually all hot water waste.

For property owners, this means lower operating costs and a cost-effective way to upgrade existing buildings. For users, it delivers immediate comfort with hot water on demand. And for society, it offers a sustainable shift: reducing resource consumption, cutting emissions, and relieving infrastructure – a vital step forward in an era of rising energy prices, growing water scarcity, and ambitious climate targets.

Ambidex

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.

Logotype Valys

Valys

Water treatment plants struggle to optimize their processes due to a lack of precise real-time data on water quality parameters such as dissolved organic carbon (DOC) and its reactivity. Inefficient dosing of chemicals and overuse of activated carbon result in high operational costs, unnecessary environmental impact, and make it difficult to meet stringent water quality regulations.

Valys offers a state-of-the-art optical sensor that provides continuous, real-time monitoring of DOC and other key water quality parameters. Our patented solution gives operators the data they need to optimize treatment processes, reduce chemical usage, and increase the longevity of activated carbon filters. By integrating our sensors, water treatment plants can achieve improved operational efficiency, reduce costs and labor, and minimize their environmental impact.

 

 

Algeno

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.

Smena

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.

Eneryield

Accelerating the electrified society through energy analytics, protection- and control of electricity flow using machine learning and deep learning.

Enairon

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.

Mimbly

Mimbly

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.

Modvion

Modvion offers a modular, high altitude tower while simplifying transportation. The company builds with a light, low cost, and renewable material: laminated timber. The tower reduces production cost by 40 % and the cost of wind energy by 6 %. Increased yield due to 40 % lower tower cost -> 6 % lowered cost of wind energy.

  • Simplified logistics in inaccessible areas
  • CO2 -neutral wind power from the first kWh
  • Enhanced local acceptance of wind power due to the material
  • Reduced weight
