Greg, list et al: 1. I agree with your concerns and guidance. Thanks. 2. Yesterday a White House document was released that implies our US Federal Agencies will be looking hard at CCS (among other things). Maybe a concerted effort by some on this list could broaden the assignments handed out to a range of agencies to include CDR (as is being done throughout the EU). I see many places that biochar could qualify.

About two-thirds of the roughly 30 gigatons of carbon dioxide released by human activity each year comes from the power sector and industrial activities such as oil refining and fertilizer production.

'Great bumper sticker' While increased use of nuclear, solar and wind power could replace some coal, gas and oil-fired power plants, they are not an option for most industrial sources of carbon dioxide, he added.

To boot, global greenhouse gas emissions are higher than they have ever been and we are building more coal plants every year, Steven Davis, an earth systems scientist at the University of California, Irvine, told NBC News.In fact, current emission and construction trends suggest that the international goal to limit warming to 3.6 degrees Fahrenheit is completely implausible, he said during a presentation of his research at a recentclimate conference in Seattle. Getting anywhere close to the goal, he added in a follow-up interview, will almost certainly require massive deployment of solar and nuclear power along with CCS.But there is a big cost associated with CCS, he noted. It is like 40 or 50 percent more expensive to get energy from a fossil plant if it has CCS. How CCS works Carbon capture and storage is a basket of technologies used to prevent carbon dioxide from escaping to the atmosphere in the course of power generation and other industrial activities. The captured gas is typically injected deep underground where, in theory, it will stay forever. In some cases, this injected gas is used to force out remnant oil from underground deposits, a process known as enhanced oil recovery. It is a natural next step especially for the fossil fuel industry which sees value in CCS because it means we can continue to keep burning their products, Davis said. The Boundary Dam Power Station, owned by SaskPower, is near Estevan, Saskatchewan. The world's first commercial-scale carbon capture and storage project officially opened there this week.

Re: [geo] 'Clean Coal' With Carbon Capture Debuts in North America (Not in U.S.) - NBC News.com
Greg, Your points about underfunding of alternatives to CCS are valid but it does not follow that the remedy, either from a systems perspective or a policy perspective, is to reduce CCS funding. That might result in less funding for CCS and no increase in funding for alternatives. Many advocates for various methods of cutting CO2 emissions and/or drawdown of atmospheric concentrations suffer from a zero-sum syndrome, believing the only viable path for more funding for their favored idea is to argue that some other currently funded approach is receiving too much money. Given where we are on (not) managing human GHG emissions, it is hard to support a claim that CCS or any other approach is receiving too much money. The money may not be being spent optimally on each option but fixing that requires a more surgical approach than just saying don't spend so much. The amount of public funding for different mitigation/compensation approaches is a political matter and requires a political strategy. Part of such a strategy is developing and publicizing analyses showing the potential payoff for investing in each approach. Another, probably more important part of the strategy, is building a substantial constituency for a portfolio of approaches. For the latter, we need to map the potential constituencies and determine the valid messages that are most likely to engage and activate them. (I feel the need to add valid since so many conversations about messaging do not seem to be concerned with whether a message has validity.) I, like many active environmental advocates, assign a high priority to mitigation, with efficiency, renewable energy, and forest protection ranked at the top of the mitigation hierarchy. But I (and a number of advocates I know) do not argue for this trio of actions to the exclusion of other complementary approaches. In my opinion, all potential mitigation approaches should be provided enough private and public funding to assess whether they should be kept in a portfolio. So too with CDR concepts, with due attention paid to ecosystem impacts of such approaches. And even SRM, which I find least appealing, should in my view receive sufficient research dollars to better understand and assess the implications of real-world deployment, should our failures in other areas cause humanity to want to turn to SRM as a complement to mitigation. But to succeed in getting more funding for all these potentially meritorious approaches we need a much bigger constituency than just the members of this listserv and a handful of similar ones. We need to make the case for a portfolio in terms that will appeal first, to committed environmental advocates; second, to industrial players that understand we cannot escape bad results by simply denying the seriousness of climate disruption; third, to business interests who see a market opportunity in helping to implement a climate protection portfolio; fourth, to citizens who believe that governments have an important role to play in helping complex industrial societies pursue human development paths that minimize adverse side effects; fifth, to religious communities that recognize human responsibility to care for our planet as part of their faith. I'm sure others can add to this list. What will not succeed, I am quite sure, is the discourse that happens often on this list, where approaches not favored by a poster are dismissed as a waste and the opinions of groups who have not been persuaded to recognize the value of a broad portfolio approach to climate protection are derided as no-nothings. Greg, please understand I am not aiming these remarks at you. Your post simply stimulated me to pose this topic for a broader discussion on the list.

'Great bumper sticker' While increased use of nuclear, solar and wind power could replace some coal, gas and oil-fired power plants, they are not an option for most industrial sources of carbon dioxide, he added. Eliminating fossil fuels is a great bumper sticker, he said. It is an ineffective climate solution. To boot, global greenhouse gas emissions are higher than they have ever been and we are building more coal plants every year, Steven Davis, an earth systems scientist at the University of California, Irvine, told NBC News.In fact, current emission and construction trends suggest that the international goal to limit warming to 3.6 degrees Fahrenheit is completely implausible, he said during a presentation of his research at a recentclimate conference in Seattle. Getting anywhere close to the goal, he added in a follow-up interview, will almost certainly require massive deployment of solar and nuclear power along with CCS.But there is a big cost associated with CCS, he noted. It is like 40 or 50 percent more expensive to get energy from a fossil plant if it has CCS. How CCS works Carbon capture and storage is a basket of technologies used to prevent carbon dioxide from escaping to the atmosphere in the course of power generation and other industrial activities. The captured gas is typically injected deep underground where, in theory, it will stay forever. In some cases, this injected gas is used to force out remnant oil from underground deposits, a process known as enhanced oil recovery. It is a natural next step especially for the fossil fuel industry which sees value in CCS because it means we can continue to keep burning their products, Davis said. The Boundary Dam Power Station, owned by SaskPower, is near Estevan, Saskatchewan. The world's first commercial-scale carbon capture and storage project officially opened there this week. The carbon capture approach used at SaskPower's newly retrofitted Boundary Dam Power Plant in Saskatchewan removes the carbon dioxide with a chemical solution after the coal is burned to generate electricity. The captured gas will be used for enhanced oil recovery; some will be stored 2.1 miles deep in the Earth in a layer of brine-filled sandstone. A second method called coal gasification employs heat and pressure to convert coal into gas before it is burned, easing the removal of carbon dioxide. A Southern Company power plant under construction in Kemper County, Miss., due to come online in 2015 uses this approach. The
