The Rhodium Group, an independent research provider, estimates that, after a sharp uptick in 2018, US greenhouse gas (GHG) emissions fell by 2.1% This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. Coal-driven decline.
The Front-Loading Net Zero report states that electricity production costs could be reduced by up to 50% by 2050 if countries and states adopt 100% renewable systems faster than currently planned. Utilities should keep repeating steps 1 - 3 until their systems run on 80 – 90% renewables.
Despite the much-vaunted megatrend involving the global electrification drive and shift to renewable energy , the most ambitious pledges by Big Oil to pursue net-zero agendas remain weak at best. Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge. 2 Total SA.
The US Department of Energy (DOE) announced up to $64 million in federal funding for cost-shared research and development (R&D) projects under the funding opportunity announcement ( DE-FOA-0002057 ), “Critical Components for Coal FIRST Power Plants of the Future.”. —Assistant Secretary for Fossil Energy Steven Winberg.
While there is global potential to generate renewable energy at costs already competitive with fossil fuels, a means of storing and transporting this energy at a very large scale is a roadblock to large-scale investment, development and deployment. Generation 2 moves the Haber-Bosch process to renewable sources of hydrogen.
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.
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. Coal accounted for over 40% of the overall growth in global CO 2 emissions in 2021, reaching an all-time high of 15.3 billion tonnes. billion tonnes.
However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

Under the terms of the agreement, Energy Vault agreed to provide 1.6
Energy Information Administration (EIA) revealed that the United States generated more electricity from renewable energy sources than coal last year. According to the EIA, declining costs and rising subsidies contribute to renewables displacing fossil fuels. electric power demand through 2050 in all cases,” noted the EIA.
The US Environmental Protection Agency (EPA) released its 28 th annual Inventory of US Greenhouse Gas Emissions and Sinks (GHG Inventory), which presents a national-level overview of annual greenhouse gas emissions from 1990 to 2019. CO 2 emissions decreased 2.2% from 2018 to 2019. Total GHG emissions in 2019 were up 1.8% Source: EPA.
The intention is to set up a power-to-x competence center at the Brandenburg University of Technology Cottbus-Senftenberg and to construct a demonstration plant for the production of synthetic fuels and chemicals using electric power generated in photovoltaic and wind power plants. —Andreas Schell, CEO of Rolls-Royce Power Systems.
Aventine Renewable Energy, a leading producer, marketer and end-to-end supplier of ethanol, completed a $13.20-million million project to upgrade its wet mill ethanol plant in Pekin, Illinois, by replacing 70-year-old coal boiler technology with two newly installed Indeck high-pressure natural gas boilers.
The plant will use electricity from offshore wind turbines to produce renewable hydrogen for buses, trucks and potentially taxis. Hydrogen may also be produced by means of electrolysis, a process in which electricity is used to split water into hydrogen and oxygen.
In the new process, the supplier uses hydrogen and electricity from 100% renewable energy sources instead of coking coal in steel production. The hydrogen serves as a reduction gas, which releases and binds the oxygen from the iron ore. Unlike the use of coking coal, this does not produce CO 2 , but water.
In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas.
The CO 2 produced from the BF is used in the TC cycle to produce more CO, therefore creating a closed carbon loop, allowing for the decoupling of steel production from greenhouse gas emissions. The novel recycling system captures the CO 2 from the top gas and reduces it to CO using a perovskite crystalline mineral lattice.
Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. In both plants, natural gas turbines power the equipment.
Increased use of renewable energy will help reduce electricity generation from coal and natural gas power plants, according to the U.S. The EIA forecasts that wind and solar will together account for 16% of total electricity generation in 2023, up from 14% in 2022 and 8% in 2018.
The US Department of Energy’s (DOE) Office of Fossil Energy (FE) has selected four projects for cost-shared research and development under the funding opportunity announcement (FOA), DE-FOA-0002180, Design Development and System Integration Design Studies for Coal FIRST Concepts.
Globally, ExxonMobil expects to see growth in plug-in hybrids and electric vehicles, along with compressed natural gas (CNG) and liquefied petroleum gas (LPG) powered vehicles. A growing share of the supplies used to meet liquid-fuel demand will come from deepwater, oil sands, tight oil, natural gas liquids and biofuels.
Renewable energy and nuclear power are the world’s fastest-growing energy sources, each increasing 2.5% Natural gas is the fastest-growing fossil fuel, as global supplies of tight gas, shale gas, and coalbed methane increase. The use of liquids declines in the other end-use sectors and for electric power generation.
Other key takeaways from the November 2022 STEO forecast include: EIA forecasts renewable energy sources will provide 24% of US electricity generation in 2023, up from an estimated 22% in 2022. “We We expect notable decreases in electricity generation from natural gas and coal next year.
These facilities typically use approximately one ton of coal to produce one BBL of hydrocarbons, with a life cycle CO 2 emissions calculation that is slightly worse than equivalent fuels derived from conventional oil refining. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming.
The collapse in world oil prices in the second half of 2014 will have only a moderate impact on the fast-developing low-carbon transition in the world electricity system, according to research firm Bloomberg New Energy Finance. Saudi Arabia burns up to 900,000 barrels of oil per day to generate over 50% of its electricity.
This year’s outlook is the first to highlight the significant impact that falling battery costs will have on the electricity mix over the coming decades. BNEF predicts that lithium-ion battery prices, already down by nearly 80% per megawatt-hour since 2010, will continue to tumble as electric vehicle manufacturing builds up through the 2020s.
Total greenhouse gas emissions in the European Union (EU) decreased by 3.8% The large decline in emissions, achieved before the COVID-19 crisis, was mainly due to reduced coal use for power generation. in 2019, according to latest official data published by the European Environment Agency (EEA).
According to the IEO2021 Reference case, which projects future energy trends based on current laws and regulations, renewable energy consumption has the strongest growth among energy sources through 2050. EIA projects electricity generation to almost double in developing non-OECD countries by 2050. —Stephen Nalley.
Electra has raised $85 million to produce Low-Temperature Iron (LTI) from commercial and low-grade ores using zero-carbon intermittent electricity. By comparison, 69% of steel today is made at approximately 1,600 degrees Celsius (2,912 degrees Fahrenheit) using coal, emitting about two tons of carbon dioxide for every ton of steel produced.
The strategy is centred around two main technology routes, as introduced in the first ArcelorMittal Europe climate action report published earlier this year: The use of hydrogen in DRI-EAF (Direct Reduced Iron - Electric Arc Furnace) and, also, the blast furnace. The expansion of its Smart Carbon route, also utilizing hydrogen.
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. —Dr Birol.
The feed-stock reduction is achieved primarily by supplementing the process with oxygen and hydrogen produced by water electrolysis units that are powered by clean wind and solar generated electricity. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming.
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. s second-busiest container port.
Anticipated price hikes for coal and natural gas could lead to increase use of renewable energy in electricity generation, making both the grid and EVs cleaner, according to new United States Energy Information Administration (EIA) analysis.
The prototype will use ammonia to deliver 200kg of hydrogen a day—enough to power around 5-10 hydrogen fuel cell-electric buses. We have just 13 years to deliver a net-zero electricity grid for the UK. The traditional process of producing ammonia has used “grey” or “black” hydrogen from either natural gas or coal.
One of the common arguments you hear from people in America who are not fans of the idea of electric vehicles is that they are mostly charged from electricity produced from coal power plants. Heavy Coal Using States Accounted for Only 10% of EV Sales in 2020. of electric vehicle sales in the US. of sales.
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. EMS Energy Institute process.
All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. Wind beats coal by any environmental measure, but that doesn’t mean that its impacts are negligible. degrees Celsius.
By leveraging Siemens Gamesa’s intricate knowledge and decades of experience with offshore wind, electric losses are reduced to a minimum, while a modular approach ensures a reliable and efficient operational set-up for a scalable offshore wind-hydrogen solution. Just 1% of that hydrogen is currently generated from green energy sources.
