Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. The 1,000 wind turbines that the spheres could anchor could, on average, replace a conventional on-shore coal or nuclear plant. Earlier post.).
Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).
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. MIT: leaning toward conversion for light-duty vehicles. Earlier post.) I.e., on an energy basis at the point of use, the CO 2.
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. Click to enlarge.
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. Unity Power Alliance.
The study by researchers at MIT also points out that production of the two metals has been increasing by only a few percentage points per year.the availability of REEs appears to be at risk based on a number of factors. Comparison of demand projections for REE (total summed). Credit: ACS, Alonso et al. Click to enlarge.
A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. for oil, 24% for coal, and 20% for natural gas.
This project will develop and optimize a novel, engineered microorganism that produces a biodiesel-equivalent fuel from renewable hydrogen and carbon dioxide, at costs of less than $2.50 The aerobic microbe has been engineered at MIT and is capable of converting a variety of organic compounds into oil, from which biodiesel may be produced.
The MIT Energy Initiative (MITEI) has released a report on the proceedings—and papers that informed those proceedings—of the 8 April 2010 symposium on The Electrification of the Transportation System: Issues and Opportunities. The symposium was sponsored by the MIT Energy Initiative, together with Ormat, Hess, Cummins and Entergy.
Propane is a cleaner burning fossil fuel, yielding 87% less hydrocarbons and 50% fewer toxins than gasoline, and is more economical compared to petroleum-based options, roughly 40 to 50% less than gasoline/diesel per gallon, although less attractive on a cost per energy equivalent basis due to its lower energy content. Renewable propane.
Fuel cell system durability has improved and costs have been reduced through R&D, the ARB staff noted. In volume production, FCVs are expected to be cost competitive with other advanced vehicles, and are approaching the cost of advanced hybrid system even with current designs and high costs of materials.
Currently that means burning coal, coke, fuel oil, or natural gas, often along with waste plastics and tires. These pilot programs will need to scale up without eating profits—something that eluded the coal industry when it tried CCS decades ago. plant and burying up to 2 million tonnes of CO 2 per year below the plant. billion ($1.6
This is despite the fact that Chu, in an interview with MIT Technology Review, stated that “four miracles&# would be required for fuel cells to become viable: relating to their durability and cost; production; storage; and distribution infrastructure.
A three-year study by a team of researchers based at MIT has concluded that fundamental changes are needed in the US energy-innovation system. The study was carried out at the MIT Industrial Performance Center and involved faculty and students from nine MIT departments. Business as usual is unsustainable over the long run.
Plug-in hybrid electric vehicle technologies are not yet competitive due primarily to the high cost of advanced batteries. Ford and SCE will explore whether these batteries have other uses that could reduce their cost to consumers. But we want to give them cause to continue to press forward." ( MIT Technology Review ).
If you ask a bunch of experts to predict the cost of a technology 10 years from now, they’re all over the map—9 out of 10 are wrong, and you don’t know which one is right. So when I went to MIT to do my Ph.D., Jenkins: We have to shut down coal plants as fast as is feasible because they’re by far the most environmentally damaging.
It is simply the cost of doing business. "On some products, the costs, particularly in advanced technologies, are high," he said in a lengthy interview with Automotive News (free subscription required). Its been improving over time, but the power density and cost issues are still steep for what exists thus far.
