Optimization of solar collectors

Optimization of solar collectors

Aiguasol have designed a solar concentration called 'Ulisses'. Ulisses is a cylindrical concentrator which uses flat movable mirrors rotating on a shaft. Ulisses can be coupled to flat solar collectors or to photovoltaic modules, thereby enhancing their efficiencies and minimizing the cost of power generation. The fact that the mirrors are movable allows the structures and protective systems from wind, snow, and high temperatures to be simplified.

Optimized tap nozzles saving water

Optimized tap nozzles saving water

Conventional taps allow water to gush out at around 10–12 liters per minute – but only a fraction of that water is actually used for washing hands or rinsing plates. Altered:Nozzle “atomizes” the water, breaking it up into a high speed dense mist made out of millions of individual drops. The speed of the water is also increased up to 50 km/h. This way the user gets in contact with, and uses, every single drop of water coming out of the tap. The result is only 2% of the flow compared to a regular tap. It consists of a simple retro-fit that can be installed in less than a minute in most existing taps in the world today. This design is said to significantly reduce water consumption as well as energy.

Organic flow batteries

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

Peer-to-peer solar electricity trading platform

Peer-to-peer solar electricity trading platform

SOLshare claims to have developed the world’s first peer-to-peer solar electricity trading platform that leverages existing solar home systems (SHS) in an off-grid context to create a bottom-up smart grid. SOLshare’s SOLbox is a DC bi-directional power meter, solar charge controller and end-user device that functions as an individual node of the electricity trading network. SOLbox allows the trading network to grow dynamically from the ‘bottom-up’ as more users connect over time. SOLshare facilitates secure peer-to-peer electricity trading between users; integrating mobile money payment, data analytics and grid management services. As a SOLshare network grows, it can connect with the national grid, operating in island mode or drawing power from the grid.

Perovskite solar cells

Perovskite solar cells are developed by the University of Warsaw and represent a new class of photovoltaic devices. Their efficiency has reached 24 percent within 8 years of development, which is comparable with silicon solar panels that hav been developed for decades. Estimates say that this generation of solar cells will be significantly cheaper than panels currently available on the market. This is due to low temperature fabrication processing, simple manufacturing and cheap components. Furthermore, there is a possibility to make flexible devices which opens a brand-new application of solar panels.

Plant-based alternatives to meat

Beyond Meat creates plant-based burgers, sausages, crumbles, and other products made directly from simple plant-based ingredients. By shifting from animal to plant-based meat the company aims to solve four growing issues attributed to livestock production: human health, climate change, constraints on natural resources and animal welfare. A life-cycle assessment of the Beyond Burger suggested that compared to an equivalent beef burger, it generates 90% less greenhouse gas emissions, requires 46% less energy, use 99% less water and has 93% less impact on land use.

Portable biomass densification technology

Takachar developed technology at the Massachusetts Institute of Technology (MIT) and licensed it in order to develop small-scale, low-cost, portable biomass treatment systems that can be attached to the back of tractors, trailers, or even donkey carts. Takachar’s mobile biomass systems can then be deployed on farms in remote areas to take small pockets of biomass residues and process them onsite into a chemically densified form that is moisture-resistant and volumetrically dense. This can in turn reduce the logistical, collection, and disposal cost by about 75% compared to current alternatives such as baling and pelleting. Takachar therefore provides farmers with a cost-effective way to clear their land of crop residues rapidly after harvest.
