ONE SOLUTION FOR VINEYARDS IN ACTUAL ENERGY CRISIS.

In vineyard residual biomass is obtained that can be used locally to produce electricity, heat and biochar, when and as much as necessary, so necessary in this state of actual energy crisis. In RO 2021, 160000 ha were cultivated with vines and a minimum of 0.274 Tg.br.db dry vine ropes with an energy potential of 1.45 TWh/year would be collected. In farms from vine prunings, chopped and dried, with CHP equipment is produced electricity for own use with an efficiency of 19% and a thermal energy with efficiency of 52%. With CHAB systems heat and biocar is produced, biocar is used as an agricultural amendment or is gasified to produce gas.bc that can locally replace natural gas, or electricity production with a CHP. The vineyard activity is seasonal, the collection and storage of biomass for energy use is an investment and lockup of capital, recoverable through lower costs and the supply of energy when and as much as needed. Ecological variants with energy and economic efficiency are analyzed. Chopped and dried vine prunings as well as biochar represent an energy stock that can be used when and as much as needed in wine growing units to ensure safe and economical operation.
