Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new electrocatalyst that can directly convert carbon dioxide into multicarbon fuels and alcohols using record-low inputs of energy. At top left are transmission electron microscope images of the copper nanoparticles.

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have harnessed the power of photosynthesis to convert carbon dioxide into fuels and alcohols at efficiencies far greater than plants. Reducing CO 2 to a hydrocarbon end product like ethanol or ethylene can take up to 5 volts, start to finish.

volts to –0.5?volts volts versus the reversible hydrogen electrode) in CO-saturated alkaline water. When a voltage is applied across the electrodes of a conventional cell, a current flows and water is converted to oxygen gas at one electrode (the anode) and hydrogen gas at the other electrode (the cathode). —Matthew Kanan.

kW/h 48-volt lithium-ion battery, a Mild Hybrid Starter Generator (MHSG), a LDC converter (Low Voltage DC/DC) and an inverter. In this way, the system significantly improves the engine’s fuel economy and CO2 emissions without sacrificing maximum driving pleasure. The New Tucson combines a 48 V mild hybrid system with the 2.0

This combined combined aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance and a 12+X volt micro-hybrid stop-start and energy recuperation systems. In 2011, the HyBoost team reported that the HyBoost demonstrator was achieving comparable performance to the conventional 2.0L

Charging the batteries on a 230-volt outlet takes about seven hours. As with a torque-converter automatic, the driver can select between the gear selector positions D, N, R and P. The range of the lithium-ion batteries stabilized at 100 km (62 miles) per charge. That time is cut to just one hour on a quick charging system.

With an integrated voltage converter, the TFCM operates in a voltage range of 450 to 700 volts and most efficiently at around 30kW. The heavy-duty unit’s efficiency results in a comparatively low consumption of hydrogen relative to the power generation.
