Nevertheless, either
carbon capture and storage will have to be developed and
deployed or low - emission electricity sources, such as wind, solar and nuclear power, will have to grow significantly.
Deploying new sensors that drift with sometimes strong currents (allowing better measurement of marine snow than sensors placed on the ocean floor or tethered to the surface), the team sampled the flora and fauna and measured the amount of falling
carbon material
captured to assess the role of the ocean as a true
carbon sink.
The United States has many promising options for obtaining new supplies of electricity and changing its supply mix during the next two to three decades, especially if
carbon capture and storage and evolutionary nuclear technologies can be
deployed at required scales.
The model showed this scenario to be at the «limits of feasibility», with many of the model runs limited by the difficulty of rapidly
deploying low -
carbon technologies, such as
carbon capture and storage (CCS), in the near term.
For the past decade, governments and utilities have been looking at how
carbon capture technologies might be
deployed to reduce emission of greenhouse gas into the atmosphere, while enabling low -
carbon electricity generation.
In the near term, federal policy could: i) level the playing field between air
captured CO2 and fossil - fuel derived CO2 by providing subsidies or credits for superior
carbon lifecycle emissions that account for recovering
carbon from the atmosphere; ii) provide additional research funding into air
capture R&D initiatives, along with other areas of
carbon removal, which have historically been unable to secure grants; and iii) ensure air
capture is
deployed in a manner that leads to sustainable net - negative emissions pathways in the future, within the framework of near - term national emissions reductions, and securing 2 °C - avoiding emissions trajectories.
The limits are so low, in fact, that they essentially require new coal plants to be built with a technology that has yet to be
deployed in the power industry:
carbon capture and sequestration.
Improving energy efficiency and switching to alternative fuels, in combination with reducing the clinker content in cement and
deploying emerging and innovative technologies like
carbon capture and the use of alternative binding materials are the main
carbon - mitigation methods available in cement manufacturing.
When breakthrough technologies for the
capture and storage of
carbon dioxide are commercially
deployed and demonstrated to be effective, coal - fired electricity will strengthen its leading role in new electricity generation both in the United States and, perhaps more importantly, around the globe — especially in regions that desperately need a secure and plentiful source of affordable electricity.»
Like the fact that mercury emissions from coal fired - power plants continues to rise and that
carbon capture and storage remains an elusive pipe dream that will take another 40 years to
deploy on a commercial scale.
Carbon capture could reduce emissions from the electricity sector as well, but since it will raise the cost of producing power, the technology will not be widely
deployed until other nations adopt similar
carbon prices.
The basic technology is not new, said Ian Yeates, who heads the
carbon capture division at SaskPower, a Canadian firm which will
deploy its own version of
carbon capture later this year.
-- Fifty percent of the funds raised under this section shall be provided in the form of grants to electric utilities that had, prior to the award of any grant under this section, committed resources to
deploy a large scale electricity generation unit with integrated
carbon capture and sequestration or conversion applied to a substantial portion of the unit's
carbon dioxide emissions.
In the medium term, we are
deploying proven technologies such as cogeneration and
carbon capture and storage where technically and economically feasible.
It is also possible that mitigation techniques
deployed under JCM will expand to include critical technologies such as innovations in
carbon,
capture, and storage.
The USGS report did not evaluate the economic viability of geologic
carbon sequestration, but the cost of
deploying these types of
capture and storage technologies could be one of the main barriers to actually employing this strategy.
If
carbon capture and storage «is not widely
deployed in the 2020s,» the International Energy Agency said last year, «an extraordinary burden would rest on other low -
carbon technologies to deliver lower emissions in line with global climate objectives.»
These range from weatherizing 600,000 homes to
deploying 20,000 electric vehicle charging stations; from implementing the smart grid to
capturing and storing
carbon emissions; from restarting the nuclear power industry to investing in solar energy manufacturing, wind turbine reliability, and biofuels technologies.
As the International Energy Agency warned, â $ œno more than one - third of proven reserves of fossil fuels can be consumed prior to 2050â $ â $» unless
carbon capture and storage technology is widely
