HDF is very excited to cooperate with ABB to assemble and produce megawatt-scale fuel cell systems for the marine market based on Ballard technology.
This is important for policymakers when forecasting and influencing future emissions paths in the context of climatechange. The reasons were two-fold: (i) increased air pollution led to households staying indoors more to mitigate the pollution impact; and (ii) PM 2.5 pollution ranges between 20 and 200 ?g/m³.
Projected changes in summer mean usable capacity of power plants in the US and Europe for the SRES A2 emissions scenario for the 2040s (2031–2060) relative to the control period (1971–2000). A study published in Nature ClimateChange suggests that thermoelectric power plants (i.e., Source: van Vliet et al. Click to enlarge.
These effects are calculated with climate models, but when possible, they are evaluated with both microphysical measurements and field observations. Predominant sources are combustion related; namely, fossil fuels for transportation, solid fuels for industrial and residential uses, and open burning of biomass.
Through 2042, EPA estimates the net climate and health benefits of the standards on new gas and existing coal-fired power plants are up to $85 billion. Establishing emission guidelines for states to follow in limiting CO 2 emissions from existing fossil fuel-fired steam generating EGUs (including coal, oil and natural gas-fired units).
Pratt & Whitney was selected by the US Department of Energy (DoE) to develop novel, high-efficiency hydrogen-fueled propulsion technology for commercial aviation, as part of DoE’s Advanced Research Projects Agency-Energy (ARPA-E) OPEN 2021 program ( earlier post ). Now the concern is greenhouse gases and climatechange.
Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. A study by Mark Z. It delays action.
A “well-to-wheel” life cycle assessment (LCA) by a team from synthetic fuels producer Greyrock ( earlier post ), and the National Renewable Energy Laboratory (NREL) has determined the potential reduction of greenhouse gases and criteria pollutant emissions from the use of synthetic fuels directly converted from flare gas.
It operates at high temperatures—above the temperature for spontaneous reaction from any fuel—to enable combustion without a flame. Low-cost ceramics enable temperatures beyond the limitations of metals to deliver fuel efficiencies of power plants in small-scale distributed power. —IPG CEO Toby Gill.
The FY 2011-2012 plan focused primarily on five areas of interest: sustainable communities; behavior and technology adoption; health and air pollution exposures; air pollution science; and greenhouse gas targets. These regulations have led to considerable improvements in air quality throughout California.
A new report from the European Environment Agency (EEA) warns that the health of Europe’s most vulnerable citizens remains disproportionately affected by environmental hazards such as air and noise pollution and extreme temperatures, especially in Europe’s eastern and southern regions, despite overall improvements in Europe’s environmental quality.
The study will appear next month in the peer-reviewed journal ClimaticChange Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. However, the effects of natural gas on climatechange have been difficult to calculate.
When it comes to addressing climatechange, the “in unity there’s strength” adage certainly applies. Using age-appropriate language, the video, which is posted on TryEngineering’s climatechange page , explores the issue through visual models and scientific explanations.
Researchers from London South Bank University (LSBU), School of the Built Environment and Architecture, are investigating the use of metal hydrides to absorb, release and store hydrogen for fuel cell buses. On demand, the hydrogen is released from the hydride (endothermic reaction), utilizing the waste heat of the fuel cell.
Today, operating the best-selling gas-powered commercial leaf blower for one hour emits air pollutants comparable to driving a 2017 Toyota Camry from Los Angeles to Denver. We must look beyond transportation if we are to achieve the emissions reductions needed to fight climatechange and improve air quality and health in our communities.
When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).
The shift to electric mobility is in line with ongoing efforts to reduce the world’s dependence on fossil fuels, and reduce harmful greenhouse gas emissions responsible for climatechange. It has also contributed to environment degradation, landscape damage and soil contamination, groundwater depletion and pollution.
Since internal combustion engines will remain the primary mode of choice for mobility in the foreseeable future, both alternative (renewable) fuels and high-performance combustion concepts/ engines using fuels adapted for that purpose will be preferred for reducing the combustion impact on climatechange.
The California Energy Commission approved an $8-million grant to Equilon Enterprises—a fully owned subsidiary of Shell Oil—to develop a high-capacity hydrogen fueling station to service and promote the expansion of zero-emission fuel cell electric Class 8 drayage trucks at the Port of Long Beach.

The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.
California’s air quality programs have forced a reduction in black carbon despite a significant increase in diesel fuel consumption. The reductions occurred during a time when diesel fuel consumption increased by about a factor of five. It is also one of the major short-lived contributors to climatechange. Ramanathan.

Greater reliance on energy taxation is needed to strengthen efforts to tackle the principal source of both greenhouse gas emissions and air pollution, according to a new OECD report. The report assesses the magnitude and coverage of taxes on energy use in 2015, and considers change between 2012 and 2015.
However, the fuel-cycle PM 10 , PM 2.5 , SO 2 , and NO x emissions of EVs could be up to five times higher than those of ICEVs (internal combustion engine vehicles) and CNGVs. The preferred fuel path(s) will depend to a great extent on their climate and environmental performance, which is of national concern. Earlier post.]
The people whose business model is to wreck the ecology and the climate and profit from it. These are the people who in the face of science that says we must transition from fossil fuels to renewable energy or destroy the futures of our children and all who come after them, still want to drill for oil that should never be burned.
The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climatechange [kg CO 2 -eq.]. The top sample above shows climatechange impact; the subsequent chart shows human toxicity. Sample results from Carculator. Depletion of fresh water reserves [m 3 ].

Manufacturers would have to produce, in addition to older, heavier or polluting models, a sufficient number of cleaner—or more fuel efficient—models to achieve a balance of 147g in 2020, or face penalties. ClimateChange Emissions Europe Fuel Efficiency Policy'
When concentrations of acidic sulfate from fossil fuel emissions decrease while the concentration of more basic ammonium molecules in the atmosphere stay constant, liquid water droplets in clouds become less acidic. This makes conversion of sulfur dioxide to sulfate more efficient.
