Elizabeth Payne points out that carbon capture and storage — which the Harper government has committed millions in funding to — will need a meaningful price on carbon to succeed.

Hydrogen, which can be produced from natural gas through Steam Methane Reforming - at which point the carbon needs to be captured - is the ultimate green gas: it emits no carbon when combusted.

Even with innovation and scaling up, we may at some point have to deploy «direct - air capture» technology, which pulls carbon dioxide out of the atmosphere.

He writes that economists got around the original «make or break point» by adding what he describes as negative emissions — the removal of greenhouse gases from the atmosphere during the second half of the century by things like carbon capture and storage.

The study's authors point to a future with greater reliance on nuclear and renewable energy, reducing emissions through new technologies that capture and store carbon dioxide, and expanding forests to naturally absorb and store carbon.

My friends at The Times Green blog have rounded up news pointing to the persistent political appeal of developing ways to burn coal while capturing and disposing of the flood of resulting carbon dioxide emissions.

Dr. Depledge described signs of a shift in the oil kingdom's stance, including its endorsement of science pointing to big impacts from a building human influence on climate and commitment of money to pursue technologies for capturing carbon dioxide from the burning of fossil fuels and other new energy options.

Can anyone point me to literature that models and quantifies the impact of this effect on carbon capture?

Finally, this all points to another reality — that if you care about blunting the buildup of carbon dioxide in the atmosphere, you'd better start hoping for a lot more basic science on how to capture that gas cheaply and stash it away for safekeeping.

Yet this estimate assumes an energy technology portfolio that includes «renewables, nuclear energy, and fossil energy with carbon dioxide capture and storage (CCS), or bioenergy with CCS (BECCS)» (Oliver Geden highlighted this point).

To Cohen, the persistent China coal push points to the importance of intensifying work on cutting the costs of systems for capturing smokestack carbon dioxide and sequestering it underground.

CDR techniques complement carbon capture and sequestration (CCS) methods that primarily focus on reducing CO2 emissions from point sources such as fossil fuel power plants.»

Further, it is pointed out that the enhancement of carbon sinks is already included in the UN Framework Convention on Climate Change agreements, and, moreover, that IPCC projections rely on unspecified negative emissions (often inappropriately assumed to be implausibly large deployments of Bioenergy with Carbon Capture and Storage (BECCS)-RRB- to prevent high probabilities of temperature rises exceeding 2oC.

It's worth noting that despite the significant role for CCS in its scenarios, the IEA says under a 2C or higher path: «Coal - fired power plants with CCS become too carbon intensive at a certain point, since 10 - 15 % of their emissions are not captured.»

Generally, CCS involves capturing carbon dioxide emissions from power plants and other point sources before compressing, transporting and injecting it deep into the earth.

Additionally, as International Energy Agency (IEA) points out, almost half of carbon capture and storage is aimed at decarbonizing industry: steel, aluminum, oil refineries, cement, and paper mills use fossil fuel energy directly.

German Chancellor Angela Merkel backed industry plans to build dozens of new coal - fired power plants, expecting that at some point they would be able to capture the carbon dioxide and send it to subterranean burial sites.
