Reversible solid oxide cells

Reversible solid oxide cells are single devices that can both split water to produce hydrogen, as well as convert hydrogen back to electricity. Solid oxide cells typically operate at very high temperatures, which avoids the need for precious metal catalysts. However, the high temperatures mean that the materials a solid oxide cell need to have extraordinary properties. Sunfire has developed this technology to find materials that are up to the task, thus enabling the use of green electricity as a renewable feedstock for industry and mobility. The PowerCore solid oxide cell stack is Sunfire's technology for the production of steam electrolysers and high-temperature fuel cells.

Localot

Localot wrote: Localot provides an infrastructure to connect local retailers with customers in their city. This connection is achieved through a combination of an online shop with a "last-mile" delivery system based on bicycles. On our platform, customers can learn about, compare and buy their needed goods from their local shop. Through our routing system, a bike rider fetches the ordered products picked by the retailer and delivers them within a short time period. In this process, waste is avoided through a pawn system which is based on reusable packaging (e. G. Aluminium boxes). Therefore, our customers can enjoy their locally provided and emission-freely delivered products without having to stress about going shopping for themselves... Source: EIT Climate KIC's Climathon

Solar concentrators for high-rise buildings

Un1imited wrote: Global concern about electrical consumption and environmental sustainability inspired the application of solar energy in buildings. As expected, more than 60% of the world’s population will live in urban areas in 2030. Residential buildings are being built to be increasingly taller. At present, rooftops are typically used to install pv systems, however, as buildings are becoming taller, the available roof space per living unit may not be adequate to meet the energy demand of the building. On the other hand, many high-rise residential buildings have a large façade-to-roof area ratio. Building facades could therefore potentially be used for harvesting solar energy...

Mango solar

mango solar wrote: 1. 2 billion people in the world have no access to electricity. They satisfy basic energy needs through kerosene, which is expensive and harmful to health - especially for children. We from mango solar develop long-lasting solar home systems so people can enjoy clean and safe energy, 80 times brighter lighting and save up to 590 € in 5 years. In addition, we provide a robust and waterproof smartphone, enabling people access to the online world for the first time in their life. At the same time, this is the interface to our mango cloud, providing services like remote support, education and financing. This is how we’re shifting digitalization to previously unreachable areas!... Source: EIT Climate KIC's ClimateLaunchPad

Net zero refurbishments

Ecoworks GmbH has developed the Net Zero Refurbishments, which is a method to refurbish apartment houses with pre-fabric parts to achieve a lower energy demand in houses, and also to shift most of the energy used to be from a renewable source (solar power). The solution uses photovoltaic cells and a heat pump to reduce the electricity needed from the grid. This means that no heat from the grid is needed, however some electricity would be externally provided to meet the demand.

Mvua Nzuri!

Mvua Nzuri wrote: Typically, the soil type is not consistent throughout the field. It varies. Instead of pouring each and every inch of it with the same intensity, it makes more sense to irrigate certain areas only when really necessary.  to determine the need, we have developed low-cost, wireless sensorpacks that can be put anywhere into the soil. The sensors measure rain, brightness, humidity, soil moisture, temperature and air pressure. However, their great potential will only occur if several sensors are distributed over the field and linked with each other. Due to triangulation of the signal transit time, it is possible to calculate their relative position in the mesh... Source: EIT Climate KIC's Climathon

ORTO - Ocean Reef-Tower Oases

Sea Harmony Ltd wrote: We have developed a revolutionary aquaculture technology for the first time, combining all of the positive ecological benefits of the most effective man made reef structures. Our mussel reefs turn the ocean’s biggest problem – organic pollution into a sustainable business using unlimited resource for food production. Yet, the most important thing is that they recover the health of damaged coastal areas (more than 8 000 0000 km2 of certified “dead zones” !), by restoring their food chain – mussels, shrimp and fish (highly demanded market products)...

Green Plastics

Green Plastics wrote: We collect waste plastic materials from individuals in the communities in exchange for cash. We will communicate with these individuals through our ap where they will tell us their address and take a picture of their collection. Though this we create a source of income for the old ,disabled and unemployed. We will then sell the plastic bottles we accumulated to plastic recycling companies/projects . The rest of the plastics will go to our factories where they will be reinforced using pyloritic liquifaction and mixed with molten zinc to make the plastic stronger. We will then turn the 'new' plastic into plastic building materials which are stronger to construction companies at a much lower price ... Source: EIT Climate KIC's ClimateLaunchPad

Organic flow batteries

CMBlu Energy AG develop large-scale organic flow batteries for electrical grids. Their energy storage systems are based on renewable resources as a key technology for the energy transition and enable nationwide grid infrastructure for electromobility. The organic electrolytes are produced from the natural source lignin, which is available in almost unlimited amounts in the pulp and paper industry. Lignin derivates are obtained very cost- effective from waste streams of existing mills. They claim that their technology enables storage capacities of 1250 GWh every year only using existing infrastructure

Consider your consequences

Also the goal is to start to sensitize the people to know what impact every decision can have. This project only started with lorawan sensors which can controll gas, water and electricity, but it easily can be enhanced with a farm of sensors for each person. All this is achieved by telling the user how great it is what he does, and that every little bit of change is a good change. Https://deploy. Dlw2f3bpbe2qd.
