Published Scavenger nanoparticles could make fuel cell-powered vehicles a reality
(via sciencedaily.com) Engineers have developed a material that could give fuel cell systems a competitive edge over the battery systems that currently power most electric vehicles.
Published New method purifies hydrogen from heavy carbon monoxide mixtures
(via sciencedaily.com) Refining metals, manufacturing fertilizers and powering fuel cells for heavy vehicles are all processes that require purified hydrogen. But purifying, or separating, that hydrogen from a mix of other gases can be difficult, with several steps. Chemical engineers have now demonstrated that the process can be simplified using a pump outfitted with newly developed membrane materials.
Published Fuel from waste wood
(via sciencedaily.com) According to the latest assessment report from the Intergovernmental Panel on Climate Change, a considerable reduction in CO2 emissions is required to limit the consequences of climate change. Producing fuel from renewable sources such as waste wood and straw or renewable electricity would be one way to reduce carbon emissions from the area of transportation.
Published Carbon-coated nickel enables fuel cell free of precious metals
(via sciencedaily.com) A nitrogen doped carbon-coated nickel anode can catalyze an essential reaction in hydrogen fuel cells at a fraction of the cost of the precious metals currently used, researchers have found.
Published Wind, solar could replace coal power in Texas
(via sciencedaily.com) A fraction of the wind and solar projects already proposed in Texas could eliminate the state's remaining coal power plants and their emissions, according to engineers.
Published Could we make cars out of petroleum residue?
(via sciencedaily.com) Researchers have developed a way to make lightweight fibers, for possible use in the bodies of cars, out of an ultracheap feedstock: the waste material from the refining of petroleum.
Published Greater greenhouse gas reductions for pickup truck electrification than for other light-duty vehicles
(via sciencedaily.com) Major automotive manufacturers are ramping up production of electric trucks as a key strategy to reduce the greenhouse gas emissions of their vehicles.
Published New, nature-inspired concepts for turning CO2 into clean fuels
(via sciencedaily.com) Researchers have developed an efficient concept to turn carbon dioxide into clean, sustainable fuels, without any unwanted by-products or waste.
Published From the streets to the stratosphere: Clean driving technology enables cleaner rocket fuel
(via sciencedaily.com) Original source A chemical used in electric vehicle batteries could also give us carbon-free fuel for space flight, according to new research.
Published Fueling a hydrogen revolution
(via sciencedaily.com) Researchers show how magnetic flux sensors can be used to monitor the operation of proton exchange membrane fuel cells that run on hydrogen. By detecting changes in current, failure states due to incorrect water levels can be identified. This work may lead to cost-effective sustainable energy generation for electric vehicles.
Published A 'fairly simple' breakthrough makes accessing stored hydrogen more efficient
(via sciencedaily.com) A new catalyst extracts hydrogen from hydrogen storage materials easily and efficiently. The process occurs at mild temperatures and under normal atmospheric conditions, without using metals or additives.
Published JET fusion facility sets a new world energy record
(via sciencedaily.com) European scientists have achieved a major success on the road to energy production through fusion plasmas: They produced stable plasmas with 59 megajoules of energy output at the world's largest fusion facility, JET, in Culham near Oxford, UK.
Published Massive methane emissions by oil and gas industry detected from space
(via sciencedaily.com) For the first time ever on a global scale, using satellite imagery, scientists have quantified volumes of massive methane emissions due to fossil-fuel extraction activities and their impact on the climate. Their findings partly explain why official inventories generally underestimate the volume of these emissions. Stopping these releases, be they accidental or deliberate, would save those countries responsible billions of dollars.
Published Fuel cells and game-changing tech to remove 99% of carbon dioxide from air
(via sciencedaily.com) Engineers have demonstrated a way to effectively capture 99% of carbon dioxide from air using a novel electrochemical system powered by hydrogen.
Published New polymer fuel cells can operate at higher temperatures
(via sciencedaily.com) Original source A new high-temperature polymer fuel cell that operates at 80-160 degrees Celsius, with a higher-rated power density than state-of-the-art fuel cells, solves the longstanding problem of overheating, one of the most significant technical barriers to using medium-and heavy-duty fuel cells in transportation vehicles such as trucks and buses.
Published How fuel poverty 'gets under the skin'
(via sciencedaily.com) Original source New research shows that fuel poverty makes people's physical and mental health worse. Researchers found that not being able to keep homes warm enough affects people's levels of life satisfaction. But they also found that it impacts people's physical health by causing higher levels of inflammation, measured by fibrinogen, a blood-based biomarker.
