Cities have become the focus of global climate mitigation efforts because as they are responsible for 60-70% of energy-related CO2 emissions. As the world is increasingly urbanized, it is crucial to identify cost-effective pathways to decarbonize and enhance the resilience of cities, which ensure the well-being of their dwellers. In this study, we propose a SolarEV City concept, in which integrated systems of cities roof-top photovoltaics and electric vehicles (EVs) supply affordable and dispatchable CO2-free electricity to urban dwellers.
The SolarEV City assumes that 70% of toof-top of cities at maximum are used for PV and all passenger vehciles are converted to EV in cities being used as batteries for PV electricity. We conducted technoeconomic analyses to evaluate the concept in terms of CO2 emission reduction, cost savings, energy suffciency, self-sufficiency, self-consumption for nine Japanese urban areas (Kyoto City, Hiroshima City, Korimaya City, Okayama City,

At cruising altitude, airplanes emit a steady stream of nitrogen oxides into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. Nitrogen oxides, or NOx, are a major source of air pollution and have been associated with asthma, respiratory disease, and cardiovascular disorders. Previous research has shown that the generation of these chemicals due to global aviation results in 16,000 premature deaths each year.
Now MIT engineers have come up with a concept for airplane propulsion that they estimate would eliminate 95 percent of aviation s NOx emissions, and thereby reduce the number of associated early deaths by 92 percent.

BROOKLYN, New York, Tuesday, January 12, 2021 - Beginning in January, the Urban Future Lab at the NYU Tandon School of Engineering will be the U.S. landing pad for Innovate UK s Global Incubator Programme (GIP), which is designed to cultivate and support the launch of innovative cleantech companies with a strong potential to scale internationally to new markets.
The program will provide eight U.K.-based businesses with the opportunity to explore the potential of the U.S. market and access to world-class mentors. The cohort will consist of businesses in electric mobility, distributed energy, and technologies focused on reducing greenhouse gas emissions or addressing the effects of global warming.
A new method to analyze chemical status of lithium was developed by using a synchrotron-based scanning transmission soft X-ray microscope (STXM). A key of the method is installation of a newly designed X-ray lens, a low-pass filtering zone plate, to the STXM to improve quality of a monochromatic X-ray. 2-dimensional chemical state of a test electrode of Li-ion battery was successfully analyzed with spatial resolution of 72 nm.

With ever-worsening climate change, there is a growing need for technologies that can capture and use up the atmospheric CO
2 (carbon dioxide) and reduce our carbon footprint. Within the realm of renewable energy, CO
2-based e-fuels have emerged as a promising technology that attempts to convert atmospheric CO
2 into clean fuels. The process involves production of synthetic gas or syngas (a mixture of hydrogen and carbon monoxide (CO)). With the help of the reverse water-gas shift (RWGS) reaction, CO
