The benefit of electrical melting is that it is not only a proven technology, but it''s already available today for large-scale glass furnaces all over the world. As a result, we expect that by between 2030 to 2040, electrical boosting, or melting, will represent more than 50 per cent of the total melting energy for most new and cold-repaired glass …

Latent heat thermal energy storage (LHTES) devices aid in efficient utilization of alternate energy systems and improve their ability to handle supply–demand fluctuations. A numerical analysis of melting performance in a shell-and-tube LHTES unit in the presence of a direct current (DC) electric field has been performed.
