Electrochemical CO2 Reduction on Metal Electrodes
Abstract: Carbon dioxide is a probable carbon resource plentiful on earth. It is also a greenhouse gas with a rapidly increasing atmospheric concentration during the last two centuries. Carbon dioxide can be electrochemically reduced to useful products under mild conditions. However, the energy conversion efficiency is low that, may discourage practical application of CO2 reduction in the very near future. However, the significance of the CO2 reduction will be re-evaluated in …

Design and Fabrication of Pedal Operated Air Compressor
Abstract: The first idea for powering the pump would be a stationary bicycle. Pedal power is simple, efficient, and practical. Its most familiar use is the bicycle for personal or cargo transportation. But pedals can also power small stationary machines. Since the system is to remain human powered and large amounts of power are required, having the operator use their stronger leg muscles was intuitive. A stationary pedal driven device seemed …

Techno-Economic Analysis of Packed Bed Type Thermal Batteries for Surplus Renewable Energy Storage
Abstract: Low carbon electricity from renewables will form the bed rock of the energy transition necessary for climate change mitigation. However, variable renewable generators suffer from intermittency and variability – there can be large surplus power available at times which cannot be dispatched to the grid. At many times, the practice is to curtail surplus renewable output, which is wasteful and not economic. There are also phases when generation is not …
