We are BioThrust, a biotech startup based in Germany that brings (sensitive) cell production to industrial scales. Our bionic bioreactor employs an artificial lung, providing stress-free cultivation conditions to achieve higher cell concentrations and quality. Through our patented membrane stirrer, we provide bubble-free gas exchange for any process. The formation of foam is completely avoided while gas transfer rates are 30x what conventional bioreactors offer. Our membranes allow you to increase your space-time yield by up to 250% without harming cells. By efficiently scaling the cell cultivation process, we help provide affordable stem cell therapies as well as driving progress in other sectors like cultured meat and synthetic biologics. We are a spin-off from the RWTH Aachen, on a mission to make stem cell therapy accessible for everyone.

To achieve net-zero by 2050, the global hyperloop network is an indispensable piece of the puzzle. We enable convenient and sustainable high-speed transportation for everyone with the global hyperloop network. In the hyperloop, vehicles travel autonomously through a network of low-pressure tubes. Every trip is direct towards your destination without any stops in between. For the users, departures are on-demand, with transport times a fraction of what is offered by other modalities, while pricing is competitive. For the infrastructure owners, hyperloop is easy to integrate into the environment, has low energy consumption and emissions, and has a low total cost of ownership. We are Hardt Hyperloop. We envision a world where you can live, work and be, wherever you want, whenever you want. You have the world and everything it has to offer within arm’s reach. Join us in building future-proof transportation for a sustainable and hyper-connected world.

air up® is so much more than a water bottle. As the world’s first refillable drinking system that flavors water through scent alone: it’s a hydration revolution. Whats meant by this? Science shows that the majority of what we perceive as flavor is actually derived from scents. Our one-of-a-kind drinking system transports carefully-crafted flavors from our pods through the mouth all the way to your olfactory receptors - and thats when your brain perceives the scent as flavor. This is called “retronasal olfaction” - just drinking water, but perceiving it as a flavored beverage. Mind-blowing, we know. But it’s just science.* Since its launch in Europe in July 2019, air up® has grown into a company that operates in over 11 countries, has more than 300 employees, and enjoys a customer base in the millions. Interested in following the #thinknewdrinknew journey? Check us out on Facebook and Instagram. Let’s make scents of it [together]. *Link to study regarding taste found here: https://flavourjournal.biomedcentral.com/articles/10.1186/s13411-015-0040-2#:~:text=It%20is%20frequently%20asserted%20that,from%20the%20sense%20of%20smell.

KRAFTBLOCK is an energy storage system that is able to decarbonize industries like steel, glass or ceramics, food, chemicals or paper. It will even help renewables to have their break-through in industrial heating. The modular and easily scalable system is based on a newly developed storage material that consists of app. 85% upcycled materials. It can store up to 1.2 MWh thermal energy at a temperature level up to 1,300 °C. Due to its modular character, a single module might also be used as a mobile storage unit, that enables you to charge the storage in one place, transport it by truck or train to another place and utilize the heat at the new location. We decarbonize by storing and utilizing formerly lost or wasted heat. This means Kraftblock minimizes the usage of fossile fuels, avoids the formation of carbon dioxide and increases the economic value of formerly lost or wasted energy.
