CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario.

5 Big Ideas for High-Temperature Superconductors

Cars That Think

In 1911, Dutch physicist Heike Kamerlingh Onnes plunged a mercury wire into liquid helium and noticed that the wire’s electrical resistance vanished. It refers to materials that superconduct above −195.79 °C, the boiling point of liquid nitrogen. HTS induction heaters promise to halve energy use, along with greenhouse gas emissions.

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

Green Car Congress

Project Volt Gas Volt is based on a long-term financing plan and the use of existing technologies for the large-scale conversion of surplus renewable electricity to methane, with subsequent reuse. Project VGV uses surplus electricity generated by renewable and nuclear sources to produce hydrogen via electrolysis. Earlier post.).

Taking the Measure of the Earthquake That Destroyed Tokyo

Cars That Think

The violent vertical thrusts of the quake ruptured gas lines and water mains. In Tokyo, the fires merged into a firestorm so intense that it created its own wind system and set alight the city’s many wooden buildings. When the ground shook, the mercury would close an electrical circuit and stop an attached clock.

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

EV Info

Clueless ministers are scrambling to shore up a key part of the country’s net zero carbon strategy after the findings in a peer-reviewed study suggested that even hydrogen produced using allegedly low-emission methods can be more polluting than gas or coal. The report notes. Hydrogen can also be generated by electrolysis of water.

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

Green Car Congress

The same highly electrified scenarios, however, could not satisfy 80% GHG-reduction targets, even assuming 80% decarbonized electricity and no growth in travel demand. Within the transportation sector, the two basic options for reducing petroleum use and greenhouse gas (GHG) emissions are fuel-use reduction and fuel substitution.

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.
