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
DICE involves converting coal or biomass into a water-based slurry (called micronised refined carbon, MRC) that is directly injected into a large, specially adapted diesel engine. CSIRO is excited about the potential for DICE to lower power costs, halve carbon dioxide intensity and create a new export market for both brown and black coal.
Accelergy Corporation has begun production of a synthetic fuel from coal and biomass, to be evaluated by the United States Air Force (USAF) as the industry benchmark for 100% synthetic jet fuel. The pilot facility will also provide a tool for evaluating new coal and biomass feedstocks as the technology moves towards commercial deployment.
The National Energy Technology Laboratory (NETL) has released a follow-on study to its 2009 evaluation of the economic and environmental performance of Coal-to-Liquids (CTL) and CTL with modest amounts of biomass mixed in (15% by weight) for the production of zero-sulfure diesel fuel. This equates to diesel prices in the range of $2.70

A report from MIT and The University of Texas at Austin urges the US to accelerate efforts to pursue carbon capture and storage (CCS) in combination with enhanced oil recovery (EOR), a practice that could increase domestic oil production while significantly curbing emissions of carbon dioxide. CO 2 could be employed.
The US Department of Energy (DOE) selected eight projects to advance the development of transformational oxy-combustion technologies capable of high-efficiency, low-cost carbon dioxide capture from coal-fired power plants. The Energy Department’s $7 million investment—leveraged with recipient cost-share to support approximately $9.4
BG Group has approved implementation of the first phase of a US$15-billion project to convert coal seam gas (CSG) to LNG—the first major commercial project to do so. Total gross discovered coal seam gas reserves and resources presently amount to an estimated 17.3 Those contractors include: Bechtel Oil and Gas, Inc.,
Gasoline section shows results for fuel derived from both conventional oil and oil sands. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty whether shale gas emissions are actually lower than those of conventional natural gas.

Comparison of coal consumption and CO 2 emissions for co-production and separate production of liquids and power. Conventional CTL plant gasifies coal to produce a syngas which is then converted in a Fischer-Tropsch reactor to products. Even with CCS, the liquid product costs are comparable to recent crude oil prices.
Crude and lease condensate includes tight oil, shale oil, extra-heavy crude oil, field condensate, and bitumen (i.e., oil sands, either diluted or upgraded). Other liquids refer to natural gas plant liquids (NGPL), biofuels (including biomass-to-liquids [BTL]), gas-to-liquids (GTL), coal-to-liquids (CTL), kerogen (i.e.,

Southern Research Institute (SRI) entered into a cooperative agreement with the US Department of Energy (DOE) to develop a mild liquefaction process that will economically convert biomass to petroleum refinery-ready bio-oils. Other liquefaction processes either use severe conditions or expensive catalysts to achieve stability.
In contrast to arguments that peak conventional oil production is imminent due to physical resource scarcity, a team from Stanford University and UC Santa Cruz has examined the alternative possibility of reduced oil use due to improved efficiency and oil substitution. 2010, to above 140 $/bbl in constant 2010 dollars).
The EMS (Earth and Mineral Science) Energy Institute at Penn State has developed a conceptual novel process configuration for producing clean middle-distillate fuels from coal with some algal input with minimal emissions. Principal inputs are coal, water, non-carbon electricity, and make-up solvent. Schobert (2015) Click to enlarge.
billion went to traditional sources—such as coal and oil—and $2.3 billion went to carbon capture and storage, which is designed to reduce greenhouse gas emissions from coal-fired power plants. More than half the subsidies for renewables—$16.8 Of the fossil fuel subsidies, $70.2 ELI Senior Attorney John Pendergrass.
Oil accounts for most of this decline as, for the first time, global consumer spending on oil is set to fall below the amount spent on electricity. This could be particularly detrimental to the outlook in some developing countries, where financing options and the range of investors can be more limited. —Dr Birol.
The government of Jordan has concluded negotiations with Shell for the in-situ production of oil from oil shale. In December, the Natural Resources Authority (NRA) forwarded to the Cabinet the commercial deal it initially signed with the Royal Dutch Shell Oil Company to tap the Kingdom’ss vast amounts of oil shale.

The Canadian oil sands are now poised to become the number one source of US crude oil imports in 2010, according to new research from the IHS CERA Canadian Oil Sands Dialogue. That WTW range is lower than that determined by a number of other studies, IHS CERA notes.).
China’s shift toward alternative fuels in order to cut its reliance on imported oil is creating large opportunities, notably in natural gas vehicles (NGVs) and in the conversion of coal to ethanol, according to a new report from Lux Research. China is seeking to reduce its imports of oil from the current 50% of domestic demand.
Pyrolysis bio-oils are produced by the thermal decomposition of biomass by heating in the absence of oxygen at more than 500 °C; fast pyrolysis of biomass is much less expensive than biomass conversion technologies based on gasification or fermentation processes. The gasoline-range alcohols can be high-octane gasoline additives.
Energy executives expect continued volatility in the price-per-barrel of oil for the remainder of the year, with 64% predicting crude prices to exceed $121 per barrel. Only 35% think current crude prices are near the high they expect for oil this year, predicting the peak will be between $111 and $120 per barrel.
A decade later, fossil fuels continue to constitute 80% of global energy consumed—as they have since about 1910, when coal consumption surpassed that of biofuels, the researchers wrote. Costs ranged from a low of 0.3% 5 consumer of oil,” Krane said.
The five different fuel groups were those derived: from conventional petroleum; from unconventional petroleum; synthetically from natural gas, coal, or combinations of coal and biomass via the FT process; renewable oils; and alcohols. million bpd. Reduced GHG impact. For CTL, life-cycle GHG emissions would roughly double.
A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. This is not the same as crude oil occurring naturally in shales, as in the Bakken.
