With the recent financial upheaval and gloomy prognosis for the global economy, the price tag for alternative energy will surely get a harder look. Europe, for one, has just priced out the cost of investing in carbon capture and storage, estimating that it will take about $15 billion in public funds and subsidies to jumpstart the yet-to-be-proven technology. The Guardian explains:

One of Gordon Brown's pet energy projects - to build up to a dozen pilot plants to capture and store carbon dioxide as power stations burn coal to generate electricity - would require EU subsidies of as much as 10bn [USD $14.8 million] over the next few years, it emerged yesterday. A study by the consultancy McKinsey into carbon capture and storage (CCS) showed that such plants could be economically viable by 2030 at the latest. But it would require substantial public subsidies to get 10-12 plants running by the EU target date of 2015. They cost twice or three times as much as conventional coal plants: about 2bn for the 300 megawatt plants planned by the industry, which is refusing to go ahead without public subsidies.
Europe has been the global leader in CCS research and development for decades, home to an offshore CCS platform in Norway and an ambitious pilot plant that just launched in Germany last week. The wide-ranging apprehensions about CCS still abound: as I've discussed in a previous Vine post, it's an enormously capital-intensive project that has yet to dispel concerns about potentially fatal safety hazards, and it remains unclear whether the emissions curbed will justify the tremendous expense. But should CCS be proven to be safe and far more cost-effective, it could potentially revolutionize the way the world generates baseload power, for which there aren't a huge number of alternatives (nuclear or hydroelectric, for example, neither of which are particularly green-friendly).
That being said, if anyone is going to take a chance on developing CCS, it should be done quickly, on a scale that will actually give us a broad-sweeping indication of whether pursuing this form of alternative energy will be worthwhile. As both the potential benefits and risks are so pronounced, it seems to make more sense to embark upon a large-scale cooperative effort than a patchwork of individually funded projects. Chris Davies, a Liberal Democrat MEP and the European parliament's rapporteur on CCS, argued that that EU needs "to put this financing mechanism in place very quickly, deliver it to developers, and do it at a European level. If we leave it to national capitals, I'm not confident the projects will go ahead, and time is already running out."
Europe will need to act decisively, one way or the other, if it wants to make this wager, otherwise it may just end up bleeding money on CCS over a protracted period of time without firm indications of whether further investment is worth the pain. The U.S., for its part, has made comparatively anemic investments in CCS, and it's the sort of energy project-high-risk, capital-intensive-that will have an even tougher time finding support in economically austere times. So, Europe-it looks like this one will be your call.

As I said in the previous CCS thread I'm very skeptical on technical grounds that it will ever meaningfully reduce CO2 emissions.
-> Given that carbon dioxide is the ONLY form of chemically oxidized carbon (oxidation = combustion), CCS necessarily involves physical sequestration, the physical segregation of a gas, CO2, from the atmosphere.
-> This physical sequestration must remain effective indefinitely. It does no long term good for humanity if we continue to burn coal and all the CO2 leaks into the atmosphere 200 years from now.
-> The masses of material that must be sequestered are huge. Take the mass of coal burned and multiply it by three. That's how much CO2 must be hidden away in the ground or the sea floor or wherever you plan to hide it.
-> Plans that dissolve CO2 in the oceans are really not accomplishing anything but getting us to a new equilibrium state sooner than we would otherwise. In other words, CO2 will dissolve in the sea anyway to the point of saturation, just not as quickly as without some human help. Also, this will serve to acidify the sea and accelerate loss of marine life.

A resonable goal is to achieve a 35% reduction in CO2 by, say, 2025.
Approximately 12% reduction will occur with the new CAFE standards, plug-in hybrids and, perhaps compressed natural gas usage as a transportaion fuel.
Another 9% can come from converting 20% of our power from coal to wind or nuclear.
Another 7% can come by capturing about 15% of the CO2 presently emitted from power plants. Not all of this CO2 needs to be sequestered. Some will find its way into enhanced crude oil recovery, CO2 enhanced agriculture and some will be converted to calcium carbonate.
The last 7% can come from increased energy efficiency at coal fired power plants. This will require the relaxation of counter productive New Source Review standards which make such logical revamps too costly to implement.
This plan is possible, intelligent and will produce the best bang for the buck. It requires no expansion of government subsidy programs. It only requires responsible leadership without a hidden agenda of punishing the fossil fuel industry.
