Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

Water from the Hellisheiði power plant then flows through the facility and transports the carbon dioxide roughly 2,000 meters below the surface of the Earth. The water returns to the cycle of the geothermal power plant. Furthermore, the rock in Iceland has the ideal composition for storing large amounts of CO 2.

PSI team demonstrates direct hydrocarbon fuel production from water and CO2 by solar-driven thermochemical cycles

Green Car Congress

Solar-driven thermochemical cycles offer a direct means of storing solar energy in the chemical bonds of energy-rich molecules. syngas—from water and CO 2. Schematic illustration of direct hydrocarbon (C x H y O z ) formation from water and carbon dioxide during the reoxidation of reduced ceria doped with a catalyst (Cat.).

Swiss team develops effective and low-cost solar water-splitting device; 14.2% solar-to-hydrogen efficiency

Green Car Congress

As the V OC of the presented c-Si cells is only ∼600 mV, four cells need to be connected in series to achieve stable water splitting performance. We demonstrate in this study that, thanks to their high V OC , three series-connected SHJ cells can already stably drive the water splitting reaction at unprecedented SHE. Schüttauf et al.

Purdue, EPFL team propose Hydricity concept for integrated co-production of H2 and electricity from solar thermal energy

Green Car Congress

Researchers from Purdue University and École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are proposing a new integrated process involving the co-production of hydrogen and electricity from solar thermal energy—a concept they label “hydricity”. —Gençer et al.

IBM releases fifth annual Next Five in Five list of near-term significant innovations; personalized routing for commuting/transportation makes the cut

Green Car Congress

Together, the collaboration will provide the opportunity for proofs-of-concept and extensive pilot deployments at the state and regional level to solve common commuter headaches. Batteries today have a number of problems, chiefly, the heavy metal-oxides used inside the battery greatly limit the amount of energy it can store, IBM notes.

Conventional coal-fired plants, which make water boil to generate steam that activates a turbine, have an efficiency of about 38 percent. Ultrasupercritical plants operate at temperatures and pressures at which the liquid and gas phases of water coexist in equilibrium. France sells energy to Italy, Spain, and Switzerland,” Rahman said.

Video Friday: Autonomous Car Drifting, Aerial-Aquatic Drone, and Jet-Powered Robot

Cars That Think

We propose a prototype with special designs for propulsion and thruster configuration to cope with the vast differences in the fluid properties of water and air. This paper presents a quadrotor prototype of this concept and the design details and realization in practice. Leonardo Labs, Rome, Italy.
