Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. It would be many decades before it would slow down global warming at all, and even then it would just be making a difference around the edges. Methane is an especially potent greenhouse gas.
The US National Energy Technology Laboratory (NETL) is collaborating with the University of Kentucky and their subcontractor Virginia Tech to demonstrate a novel process for the extraction of REEs from coal using plasma. However, domestic coal is of interest as a potentially abundant and easily accessible REE source in the US.
This award marks the first Advanced Class Gas Turbines in the industry specifically designed and purchased as part of a comprehensive plan to sequentially transition from coal, to natural gas and finally to renewable hydrogen fuel, and creates a roadmap for the global industry to follow. Earlier post.).
A multi-Hubbert analysis of coal production by Tadeusz Patzek at The University of Texas at Austin and Gregory Croft at the University of California, Berkeley concludes that the global peak of coal production from existing coalfields will occur close to the year 2011. Gt C (15 Gt CO 2 ) per year, according to the study.
NYK Line, Japan Marine United Corporation (JMU), and Nippon Kaiji Kyokai (ClassNK) signed a joint R&D agreement for the commercialization of an ammonia-fueled ammonia gas carrier (AFAGC) that would use ammonia as the main fuel, in addition to an ammonia floating storage and regasification barge (A-FSRB).
Global energy-related carbon dioxide emissions rose by 6% in 2021 to 36.3 billion tonnes, their highest ever level, as the world economy rebounded strongly from the COVID-19 crisis and relied heavily on coal to power that growth, according to new IEA analysis. billion tonnes, accounting for 33% of the global total.
The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.
“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. For our default assumptions (3.5% Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds.
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. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. A global warming potential of 11.6 Sand et al.
A new report from the MIT Joint Program on the Science and Policy of Global Change shows the importance of all major nations taking part in global efforts to reduce emissions—and in particular, finds China’s role to be crucial. With no global policy, the increase in warming is projected to be about 5.5 °C.
Coal’s market share of 30.3% Global energy consumption grew by 2.5% Oil demand grew by less than 1%—the slowest rate amongst fossil fuels—while gas grew by 2.2%, and coal was the only fossil fuel with above average annual consumption growth at 5.4% globally, and 8.4% was the highest since 1969.
The Covid-19 crisis in 2020 triggered the largest annual drop in global energy-related carbon dioxide emissions since the Second World War, according to IEA data, but the overall decline of about 6% masks wide variations depending on the region and the time of year. Many economies are now seeing emissions climbing above pre-crisis levels.
The base results from a study by a team at the Center for Transportation Research, Argonne National Laboratory indicate that shale gas life-cycle greenhouse gas (GHG) emissions are 6% lower than conventional natural gas, 23% lower than gasoline, and 33% lower than coal. However, the environmental impacts (e.g.,
This will be the world’s first demonstration project in which a large amount of ammonia will be co-fired in a large-scale commercial coal-fired power plant. As a fuel that does not emit carbon dioxide when burned, ammonia is expected to offer advantages in reducing greenhouse gas emissions.
The largest drop in emissions in 2012 came from coal, which is used almost exclusively for electricity generation. During 2012, particularly in the spring and early summer, low natural gas prices led to competition between natural gas- and coal-fired electric power generators.
On 26 July, the first flue gas from the natural gas power plant, the Shepard Energy Center in Calgary, Canada, was directly transformed by the C2CNT process ( earlier post ) into carbon nanotubes. The carbon nanotubes are valued at more than $100,000 per tonne—a thousand-fold greater than coal. —Prof. 2019.07.007.

Renewables are expanding quickly but not enough to satisfy a strong rebound in global electricity demand this year, resulting in a sharp rise in the use of coal power that risks pushing carbon dioxide emissions from the electricity sector to record levels next year, according to a new report from the International Energy Agency.
The COVID-19 pandemic has set in motion the largest drop in global energy investment in history, with spending expected to plunge in every major sector this year—from fossil fuels to renewables and efficiency—the International Energy Agency said in a new report.
After growing by more than 2% in 2019, globalgas use is set to fall by around 4% in 2020, as the COVID-19 pandemic reduces energy consumption across the global economies. The report shows that medium-term growth will come from increasing cost-competitiveness and increased global access to gas. Low-carbon gas.
Clariant and Siemens Fuel Gasification Technology will cooperate in the commercialization of a new, jointly developed sour gas shift (SGS) (sulfur removal) technology for coal gasification. The entrained-flow Siemens Fuel Gasifier (SFG) is able to produce syngas from a wide range of fuels, even for low ranks of coal.
This FOA, issued in August 2017, is a $50-million funding opportunity for projects supporting cost-shared research and development to design, construct, and operate two large-scale pilots to demonstrate transformational coal technologies. Some of these technologies are now ready to proceed to the large-scale pilot stage of development.
Their paper tracks fossil fuel usage and government subsidies since the the 2009 G20 summit, during which representatives from 20 countries discussed global financial and socioeconomic issues and agreed to “phase out and rationalize over the medium term inefficient fossil fuel subsidies.”. 5 consumer of oil,” Krane said.
In a new report, energy, mining and minerals consultancy Wood Mackenzie projects that despite efforts to limit coal consumption and seek alternative fuel options, China’s strong appetite for thermal coal will lead to a doubling of demand by 2030. It is very unlikely that demand for thermal coal in China will peak before 2030.
It is rapidly expanding energy use, mainly driven by fossil fuels, that explains why humanity is on the verge of breaching planetary sustainability boundaries through global warming, biodiversity loss, and disturbance of the nitrogen-cycle balance and other measures of the sustainability of the earth’s ecosystem.

Global oil demand is expected to decline in 2020 as the impact of the new coronavirus (COVID-19) spreads around the world, constricting travel and broader economic activity, according to the International Energy Agency’s (IEA’s) latest oil market forecast. The IEA now sees global oil demand at 99.9 —Dr Fatih Birol.
The result will be renewables eating up more and more of the existing market for coal, gas and nuclear. trillion being invested globally in new power generation capacity between 2018 and 2050, with $8.4 Coal emerges as the biggest loser in the long run. NEO 2018 sees $11.5 BNEF sees $1.3
MIT and the IEA both have newly released reports exploring the potential for and impact of a major expansion in global usage of natural gas, given the current re-evaluation of global supplies. The IEA takes a more conventional approach, assessing the impact on the penetration of vehicles burning gas as their fuel.
