Using Electricity to Generate Alternative Fuel

Electrical energy generated by various methods can be difficult to store efficiently. Chemical batteries, hydraulic pumping, and water splitting suffer from low energy-density storage or incompatibility with current transportation infrastructure. UCLA researchers have demonstrated a method for storing electrical energy as chemical energy in higher alcohols, which can be used as liquid transportation fuels.

Superconducting Current Limiter

A new superconducting current limiter based on YBCO strip conductors has been installed at a power plant. At the Boxberg power plant of the Swedish company Vattenfall, the current limiter protects the grid for own consumption that is designed for 12,000 volts and 800 amperes against damage due to short circuits and voltage peaks.
