Urine Fertiliser

Farmers and researchers in Niger have conducted trials of urine fertiliser from 2014 to 2016 and achieved a 30% increase in pearl millet yield compared to standard fertiliser. Urine fertiliser is also a much more environmentally sustainable alternative to regular fertiliser.

Co2 Battery

Italian company Energy Dome have launched a large scale Co2 battery that can use captured carbon dioxide as a closed system battery. Electrical energy converts Co2 stored in a dome into compressed liquid, while storing the heat generated by the conversion. When the energy needs to be withdrawn, the stored heat is used to heat the compressed Co2 which turns a turbine to generate electricity and refill the Co2 dome.
