Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have demonstrated a room-temperature method that could significantly reduce carbon dioxide levels in fossil-fuel power plant exhaust, one of the main sources of carbon emissions in the atmosphere.
Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2.
The EPFL system captures CO 2 directly in the trucks’ exhaust system and liquefies it in a box on the vehicle’s roof. First, the vehicle’s flue gases in the exhaust pipe are cooled down and the water is separated from the gases. Researchers at EPFL have patented a new concept that could cut trucks’ CO 2 emissions by almost 90%.

An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption. This is done via exhaust gas recirculation (EGR). Dimethyl ether (DME) can be produced from hydrogen and CO2.
It then sprays the treated sea-water into the exhaust funnel, where CO 2 is converted into bicarbonates, SO 2 into sulfates and NO x into nitrates through natural chemical processes. The process water is collected, filtered, and pumped into an aft tank for further processing, and eventually returned to the ocean.
In addition to demonstrating the integration of Air Products’ vacuum swing adsorption technology, the project is also helping to verify that CO 2 -enhanced oil recovery (CO2-EOR) is an effective method for permanently storing CO 2.
Eaton’s cylinder-deactivation (CDA) technology increases the exhaust temperature at low load to allow NO x aftertreatment systems to quickly reach peak efficiency range of 250 °C – 400 °C. Hydraulic lash adjusters can also support cylinder deactivation. CDA is just one of Eaton’s variable valve actuation (VVA) technologies.
Researchers have used a novel near-infrared light imaging technique to capture the first cross-sectional images of carbon dioxide in the exhaust plume of a commercial jet engine. The researchers used their new chemical species tomography setup to capture the first images of carbon dioxide exhaust from a commercial aircraft engine.
The study found that even when the microbial factories were activated consistently for hours at a time, they showed few signs of exhaustion or depletion, indicating that the cells can regenerate and thus limit the need for rotation. The process also shows promising signs of being able to operate at scale.
Whether or not you subscribe to the theory that carbon dioxide released by human activity is to blame for global warming, theres no doubt that we do release a lot of CO2 into the atmosphere. Many countries have now introduced measures to curb those emissions, something that goes hand-in-hand with reducing reliance on fossil fuels.
The remaining two-thirds are lost as waste heat going into the environment through the car’s exhaust emissions and through the radiator. Use of the thermal energy contained in the car’s exhaust gas also offers major saving and comfort potentials.
This is to be achieved through the synergistic application of an extremely downsized gasoline engine coupled with electrified boosting and exhaust gas energy recovery; micro-hybrid functionality with stop/start, torque assist and regenerative braking; and a novel energy storage technology. The vehicle is to offer the performance of a 2.0
Direct capture of CO 2 from air, or from an exhaust stream vented to the atmosphere, represents negative emissions. When that carbon is converted into a fuel, burned, and exhausted to the atmosphere, the overall cycle is roughly neutral. In CCTF, the source of CO 2 determines the net carbon intensity of the fuel, Kreutz says.
The engine’s dual-circuit cooling system and integrated water-cooled exhaust manifold enable short engine warm-up times. The two overhead camshafts are driven by toothed belts; the intake camshaft is variable, further reducing emissions and fuel consumption and improves the power curve in the lower rev range.

They then installed a port-fuel injection system for gaseous fuels; a low-pressure exhaust gas recirculation system; and cylinder-pressure sensors in all four cylinders.
The combustion of 1 liter of diesel fuel produces approximately 11% more energy than gasoline fuel, but the diesel fuel also releases approximately 11% more CO2 due to its higher carbon content. On top of the higher energy density of diesel fuel, diesel engines historically possessed a number of efficiency advantages over gasoline engines.
The entire extracted gas volume then is reintroduced into the FGD outlet transition duct where it is mixed with the FGD exhaust gas. In this research pilot plant, however, the CO 2 is remixed with the treated flue gas after process discharge sampling measurements.
The funding will be used for the design of a demonstration system that will capture carbon dioxide from exhaust stacks at Honeywell’s manufacturing facility in Hopewell, Va., UOP, a Honeywell company, has been awarded a $1.5 and deliver the captured CO 2 to a cultivation system for algae.

An advanced waste heat recovery system captures and reuses energy from the engines’ exhaust gas for extra propulsion with less fuel consumption. When exhaust gas leaves the engine, it has a very high heat potential. Utilizing this potential in an exhaust gas boiler, it is possible to generate steam.
In this way, the cost of exhaust-gas treatment can be reduced, Bosch adds. Carbon-neutral combustion engines that run on synthetic fuels are thus a very promising path to explore—including for passenger cars. In addition, synthetic fuels can be designed to burn practically soot-free.
