The Big Bang for the energy industry!

First there was the Big Bang, then there was hydrogen.
What connects them both? The potential to create something new!

Our Vision ...

is to add a missing component to the hydrogen world-
an effective storage and distribution solution.
This is needed to help us get to a hydrogen society, faster and safer.

Our deepest driving force is to restore harmony and balance to our planet, and we will achieve this through offering new technological solutions.

With this in mind, four visionaries from Munich, Porto and Uppsala founded the internationally networked technology start-up Water Stuff & Sun.
Today experts in the field of hydrogen storage and microsystem technology are working in cooperation with selected European research institutions and together they are developing the unique system of the Sfeers!

Our storage solution creates
new opportunities

Water Stuff and Sun Hydrogen Sfeers

For a long time it has been a challenge to come up with a way to take hydrogen vehicles longer distances. This is no longer a problem with Water Stuff & Sun‘s innovative and unique Sfeer technology.

Another challenge for the hydrogen advocates has been the issue of safety. With the Sfeers the level of safety is much higher than the demands on gasoline and diesel of today. The solution is to have a large number of small (around 40 mm) spherical high pressure tanks (up to 1000 bar) that simultaneously release hydrogen depending on the environmental pressure. One integrated low pressure tank, customized to the vehicle body, contains thousands of Sfeers that with a kind of swarm intelligence open and close all at same time, contributing to a common hydrogen mass flow.

This opens up completely new opportunities for implementation in cars and all other high energy demanding mobile applications, like drones, air taxis etc.

Imagine a world where the only waste from cars was water. With Water Stuff & Sun Sfeers it's not only possible, it's a reality!

There is a reason why things tend to become spherical. Mother earth is a perfect example of this. Don´t fight nature, work with it. Work with us!

The desire

Cool down with new solutions

world climate hydrogen hydrogen cloud gas climate

As many people know today the human impact on climate change is great and the consequences are obvious: rising sea levels, shrinking glaciers, severe weather events and threats to habitants.

We are convinced that the solution lies within the transformation of energy production, storage and usage. A shift away from fossil fuels towards sustainable and climate friendly technologies and products.

It is high time to move forward with new technologies and finally welcome a circular economy and way of life, in harmony with nature.

The technology

Easy and efficient

The Sfeer technology presents an innovative energy and gas storage solution based on high pressure technology, which elegantly and efficiently solves many problems related to conventional high pressure cylinders. This technology is the solution to the hydrogen storage problem and an important stepping-stone towards a Hydrogen Society.

Water Stuff and Sun hydrogen storage Sfeer Sfeers

Each Sfeer is equipped with an intelligent micro mechanical control chip

  • The Water Stuff & Sun Sfeer is about the size of a ping-pong ball.
  • It can store significantly more gas than any other method today.
  • Since the total volume is fragmented across thousands of small tanks, the safety function of the complete storage system is multiplied to a thousand times redundancy, making it the safest fuel ever made.
  • Sfeers can be re-used thousands of times.

The micro mechanical chip

  • The micro mechanical chip is mounted on the inside of each small spherical tank and connects the Sfeer with its environment.
  • The chip contains all mechanical structures needed for filtration, valve control, pressure regulation, etc.
  • The internal and ambient pressures control the gas flow to and from the tank. No electrical or mechanical stimuli is needed in the process.

The Sfeers intelligent valve system comes from the world of satellites, which benefits greatly from small and lightweight control components.

Lars Stenmark

Inventor

Lars Stenmark was already a legend within the space industry while he was alive. At the end of his career he was active as a professor in micro and nanotechnology at Uppsala University. He combined his experience from constructing space applications, where there is an emphasis on making things light and small, with his deep climate awareness to develop the Sfeers.
In the process he became known as the man who “brought space down to earth“.

The idea of the Sfeers first came to him when he was driving through Stockholm on his way to the patent and registration office to submit another patent application. He was so taken by the realisation of the invention he decided to pull over and stop the car. He did so for two reasons - to avoid becoming a traffic hazard and to take some serious notes. Lucky for us all that he did!

Thomas Korn

Thomas began his career as a design engineer in R&D at BMW shortly after completing his studies in engineering at Munich University of Applied Sciences. Here he developed two generations of hydrogen vehicles and started working together with Alvaro for the first time. From 2001, he led the BMW research department for fuel cell technology, before relocating to California in 2006, where he was the project manager responsible for the BMW North America H2 vehicle and filling station programme.

He then moved to Alset and took up a role as Vice-President for Technology and Innovation; this was also where he gathered first-hand experience of the start-up world. Thomas established the award-winning start-up business KEYOU, before turning his attention to Water Stuff & Sun’s paradigm-shifting Sfeer technology. As CEO and founder he is making the future of hydrogen fuel today.

Jonas Flädjemark

Jonas is a serial inventor and innovator with numerous patents, as well as several products succeeding in a variety of markets. It was 1996 when he first heard that hydrogen was the future of fuel, and he immediately began to dream of a hydrogen racing car. It wasn’t until 2008 that he got the opportunity to build one with students at Halmstad University, and it was here that he discovered the greatest problem with hydrogen was the storage and distribution of the gas.

In his search for a solution he met Lars Stenmark and within a few minutes he was convinced that the Sfeers were the answer. Together they spent the next few years developing the science and business case needed to realise their ideas.

In 2013 fate lent a hand when Thomas exhibited an Aston Martin at Le Mans that had completed the 24h Nürburgring earlier that year and Jonas presented the Sfeer concept for him. Shortly afterwards they discussed the idea of starting a company together and today Jonas is co-founder and Chief Operating Officer for Water Stuff & Sun. Today everything that could only be imagined in 1996 is real, and Jonas is one step closer to his dream of driving hydrogen racecars.

Alvaro Sousa

Alvaro has had a natural passion for vehicles since he started to walk. After realizing the damage that fossil fuels are causing he became very interested in solutions for clean mobility. The realization of a truly sustainable renewable-based Hydrogen (H2) energy economy became Alvaro’s sole motivation when he was finishing his degree in mechanical engineering in Porto.

He started his professional career at the BMW’s R&D centre in Munich soon afterwards, supporting the development of the first demonstration fleet of pre-series vehicles powered with a H2-engine, and it was here that he started to work closely with colleague and co-founder-to-be Thomas Korn. After building a solid complementary knowledge of H2 storage systems and supporting fundamental research on H2 fuel cells, Alvaro went to California to lead the H2-engine technical team that supported the North-American fleet operation of BMW’s first ever series-produced vehicles with H2-engine propulsion. Upon returning home to Porto, Alvaro became a university lecturer teaching about clean vehicle technologies and engines. He then joined Austrian and H2-engine start-up Alset, whose major achievement was to adapt an Aston Martin racecar to H2-drive and finish a 24h endurance competition.

In 2015 he co-founded H2-engine start-up KEYOU which focuses on the development of adaptation H2 kits that convert conventional engines and vehicles into clean mobility products. In 2016 Alvaro co-founded gas storage start-up Water Stuff & Sun, where he leads the technology unit, responsible for the Sfeers product development.
