Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. The intermittent nature of daylight and strong winds, however, is a stubborn problem. The apparent contradictions do not end there.

“Project Volt Gas Volt” proposes long-term financing plan to support widespread implementation of power-to-gas systems

Green Car Congress

The concept is the same embodied in Audi’s e-gas project ( earlier post ), to which the VGV proposal makes continued reference. The Green Redemption Fund could use COFACE-type mechanisms to secure the receivables of wind farms and solar installations. Hydrogen Production Natural Gas Power Generation Solar Wind'

Study projects emission impacts of inexpensive, efficient EVs: 36% further reduction in LDV GHG by 2050, or 9% economy-wide

Green Car Congress

A new study by researchers at the University of Colorado at Boulder projects the emission impacts of the widespread introduction of inexpensive and efficient electric vehicles into the US light duty vehicle (LDV) sector. The work is reported in a paper in the ACS journal Environmental Science & Technology.

Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications

Green Car Congress

These 9 combinations became the reference scenarios with defined fuel requirements and GHG emissions. The reference case scenarios assume no change to GHG intensity from current levels. The climate-targeted scenarios included cellulosic biofuel substitution to reduce GHG from light duty transportation to 20% of the reference GHG.

Daimler Trucks NA SuperTruck achieves 115% freight efficiency improvement over 2009 baseline; 50.2% engine BTE

Green Car Congress

Solar panels run the length of the top of the SuperTruck’s trailer, helping to charge the hybrid battery, which in turn powers the eHVAC system. The basic shape originated as a 3D computer model, which was carefully honed by aerodynamicists using digital wind. Aerodynamics. Fleet: Schneider, Walmart.

Government comes to realize that Hydrogen is not the answer to home boiler replacement conundrum

EV Info

The hydrogen so produced is often referred to as “gray hydrogen,” to contrast it with the “brown hydrogen” made from coal gasification. Production of gray hydrogen is responsible for 6% of all natural gas consumption globally. Hydrogen can also be generated by electrolysis of water.
