The US Department of Energy (DOE) intends to provide up to $100 million in awards ( DE-FOA-0002116 ) for the Coal FIRST (Flexible, Innovative, Resilient, Small, and Transformative) initiative (announced in November 2018), which aims to develop coal plants of the future that will provide secure, stable, reliable power with near-zero emissions.
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 US Department of Energy is awarding $620 million for projects around the country to demonstrate advanced Smart Grid technologies and integrated systems. Smart grid regional demonstrations involving plug-in vehicles include (ranked by DOE funding): Columbus Southern Power Company (doing business as AEP Ohio).

The committee also separately derived a range of values for damages from climate change; the wide range of possibilities for these damages made it impossible to develop precise estimates of cost. Coal accounts for about half the electricity produced in the US.
In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario.

Spinning reserves are power generation or storage assets that can come online quickly to serve as bridge power for the grid to maintain system frequency stability during emergency operating conditions and unforeseen. generation; and the ability of a grid operator or vertically integrated utility to call upon. load swings.
Increasing the power generating capacity of a 12-module NuScale small modular reactor (SMR) plant by an additional 25% lowers the overnight capital cost of the facility on a per kilowatt basis from an expected $3,600 to approximately $2,850.
The solution will lower the cost of hydrogen by being able to run off grid, opening up more and better wind sites. The bulk is obtained from natural gas and coal, emitting 830 million tons of CO 2 per year, more than the entire nation of Germany or the global shipping industry.
The least expensive way for the Western US to reduce greenhouse gas emissions enough to help prevent the worst consequences of global warming is to replace coal with renewable and other sources of energy that may include nuclear power, according to a new study by University of California, Berkeley, researchers.

The 1,000 wind turbines that the spheres could anchor could, on average, replace a conventional on-shore coal or nuclear plant. Preliminary estimates indicate that one such sphere could be built and deployed at a cost of about $12 million, Hodder says, with costs gradually coming down with experience.
However, the financial cost of the shift is causing concern. These costs are primarily borne by consumers. To date, renewables have had feed-in priority over conventionally generated power from combined cycle and coal-fired power plants. Siemens stands behind the energy transition. One possibility here is auctions.
They also found that the total costs of ownership (TCO) of the electric and diesel trucks are similar. Electric grid transmission and distribution efficiency (from power plants to end-use customers) is the third component. Numbers in red are net total including recycling effect.

Reduced fossil fuel expenditures more than pay for the increased costs of additional transmission in all high wind scenarios. Incorporating high amounts of wind power in the Eastern grid goes a long way towards clean power for the whole country.
We see $548 billion being invested in battery capacity by 2050, two thirds of that at the grid level and one third installed behind-the-meter by households and businesses. The result will be renewables eating up more and more of the existing market for coal, gas and nuclear. Coal emerges as the biggest loser in the long run.
In line with the government’s plan to develop a national e-vehicle industry, the project will support the establishment of an e-vehicle parts industry, battery supply chain, and charging stations, including five off-grid solar charging stations. More than 40% of Chhattisgarh’s 21 million residents live below the poverty line. million.

A coal plant in South Texas will shut down and convert to a solar + battery electricity generation facility, with the help of a $1.4 SMECI has operated a mine mouth lignite-fired coal plant (named due to its proximity to the mine that supplies it) since 1982. But that coal-fired plant is one of the dirtiest in Texas.
The costs of providing a low-speed leased BEV for local city use is far less than trying to replicate the current ownership model of all-purpose long-range ICE vehicle. System-level implications include the decarbonization of the grid and the addition of additional generation capacity. —Tran et al.
Electricity from all sources flows into the grid and is used to meet instantaneous system-wide demand. Yet owners of existing electrified vehicles are unlikely to vary their charging habits according to the quantity of bioelectricity on the grid. —Lemoine et al.
The study, in press in the Journal of Power Sources , examines the efficiency and costs of current and future EVs, as well as their impact on electricity demand and infrastructure for generation and distribution, and thereby on GHG emissions. Derive GHG emissions and costs of charging of EVs in the 2015 Dutch context and. We therefore.
Researchers at the US Department of Energy (DOE) National Renewable Energy Laboratory (NREL) are identifying battery second use (B2U) strategies capable of offsetting vehicle expenses while improving utility grid stability. —“Identifying and Overcoming Critical Barriers to Widespread Second Use of PEV Batteries”.
Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. Reduction in annual generation cost and external emissions costs due to controlled charging compared to uncontrolled charging ($2010).
Their path to cost reduction is through higher volume, resulting in the consumption of more subsidies. Further cost reduction, to a subsidy free level, can then be achieved through higher volume assisted by private funding.
However, the resulting low gas prices, as well as clean air and climate policies, will promote further switching to gas from other more polluting energy sources, such as oil and coal. India is planning to almost double the length of its gas transmission grid, while China will grow its gas network about 60% by 2025. MMbtu in Russia, $8.7/MMbtu
The IEA said that this reflects the continued domination of fossil fuels—particularly coal—in the energy mix and the slow uptake of other, lower-carbon supply technologies. Smart grids, for example, make it easier and cheaper to replace fossil-fired power with renewables without jeopardizing the reliability of the energy system.
Greenhouse gas emissions will certainly grow too, because India’s energy generation is dominated by fossil fuels—coal-fired power plants for electricity, coal- and gas-fired furnaces for industrial heating, liquid petroleum gas for cooking, and gasoline and diesel for transportation. costs less than fossil-fuel-based electricity.
Researchers at Georgia Tech have compared medium-duty (MD) electric and diesel urban delivery trucks in terms of life-cycle energy consumption, greenhouse gas (GHG) emissions, and total cost of ownership (TCO). One surprise among their findings was that the electric truck had cost advantages over the diesel vehicle under some conditions.
Deep declines in wind, solar and battery technology costs will result in a grid nearly half-powered by the two fast-growing renewable energy sources by 2050, according to the latest projections from BloombergNEF (BNEF). Each year, NEO compares the costs of competing energy technologies through a levelized cost of energy analysis.
If successful, new battery technologies developed under this program will give electrified light-duty vehicles range, performance, lifetime, and cost required to shift transportation energy from oil to the domestically powered US electric grid. Innovative Materials & Processes for Advanced Carbon Capture Technologies (IMPACCT).
Cost considerations on the total infrastructure or cost of ownership were also outside the scope of this work but are nevertheless important, they team noted. They assessed scenarios for 25% (RPS-25) and 50% (RPS-50) renewable portfolio standards for EV use along with the current US mix, natural gas, and coal. Click to enlarge.
To answer this question, we gathered data on (i) the quantity and location of emissions released from tailpipes and from upstream processes to produce and operate vehicles, (ii) the externality costs of damages caused by the release of these emissions, and (iii) estimates of externalities and other costs to the US associated with oil consumption.
This study models a single urban area with a finer grid resolution (4 km) than has been considered in previous PHEV studies, and also incorporates plume-in-grid treatment for improved tracking of plume dispersion. Brinkman et al. For other areas, where PM2.5
Tesla Energy takes a stand against coal and gas generators in Australia. Elon Musk announced Tesla’s solar neighborhood a few days after Texas Governor Greg Abbott released directives that included streamlining incentives to foster and maintain power sources like natural gas, coal, and nuclear power.
The cost of deploying a PSA system and associated refueling pump at a fueling stations will be on the order of $300,000 to $500,000, said Jeff Kissel, president and CEO of TGC during a briefing on the announcement—about one-quarter of the cost of currently installing a more conventional hydrogen fueling station in the US.
Among the findings of the survey: Approximately one-third (33.8%) of respondents felt the lack of investment to modernize the grid is a primary roadblock preventing the widespread support of EVs. 19% of those surveyed indicated the government should bear the primary burden of developing and funding an EV infrastructure or smart grid.
In addition, China also possesses an advantage in electric motors, which is partly due to its position as the dominant producer of rare earth.Rare earth materials, specifically neodymium, contribute approximately 30 percent of the material cost of permanent magnet motors, one of the key motor types used in electric propulsion systems.
Their business model dictates that they pursue the lowest-cost power source and charge the highest premiums they can for the product in an open, but federally controlled, market. These companies have sunk costs invested in coal, gas and oil plants and are content in maximizing the return on these investments. in Connecticut.
One of the fundamental themes of your book is that the technological learning curve that has resulted in the rapid reduction in the costs of renewable energy has been sustained for 50 to 70 years and shows no signs of slowing down. Unless U.S. I keep thinking that Elon Musk should not be worrying so much about autonomous cars today.
The Wind and Water Power Program is seeking Phase III proposals that will enhance the commercialization potential of utility-scale technologies that significantly decrease the cost of energy and/or improve the reliability of wind power systems. Office of Electricity Delivery and Energy Reliability.
Long Duration Energy Storage (LDES): Although LDES technology is still maturing, the LDES market has enormous potential to improve grid resilience, increase the adoption of renewable power generation, and strengthen our energy security. have had overnight capital costs over $10,000 per kW.
The objective of the Hydrogen Production sub-program is to reduce the cost of hydrogen dispensed at the pump to a cost that is competitive on a cents-per-mile basis with competing vehicle technologies. Based on current analysis, this translates to a hydrogen threshold cost of. Source: DOE. Click to enlarge.
Not only is this a massive increase in absolute terms, but as the costs of technologies fall, mineral inputs will account for an increasingly important part of the value of key components, making their overall costs more vulnerable to potential mineral price swings.
