Chemical-mechanical separation of pig slurry into a solid fraction rich in dry matter, P, Cu and Zn and a liquid fraction rich in inorganic N but poor in dry matter may allow farmers to manage surplus slurry by exporting the solid fraction to regions with no nutrient surplus. Pig slurry can be applied to arable land only in certain periods during the year, so it is commonly stored prior to fiel...

Long-duration energy storage (LDES) is a potential solution to intermittency in renewable generation. In this study we have evaluated the role of LDES decarbonized electricity systems and identified cost efficiency performance necessary for substantially reduce costs displace firm low-carbon Our findings show that capacity discharge are most important parameters. Charge/discharge charge play se...
