Carbon Capture: Possible Solutions, Pt. IV

Carbon capture and sequestration have been about research and very little about actually putting the technology to real use. In this four-part series, we'll examine some of the issues and possible solutions.

How do you combat a necessary evil on a budget? That's the dilemma with carbon capture. Scientists, policy makers and energy companies all agree that carbon dioxide from coal burning plants needs to be kept out of the atmosphere. The problem is how to do it without running up expenses that will make China, India, the United States and even Europe retreat behind years of prototype trials.

Thus far, carbon capture and sequestration (CCS) has been concerned with research and very little about actually putting the technology to real use. In Part I: Carbon Storage, the Money and the Market, we examined the history of carbon capture. In Part II: Carbon Economics, we dug into the forces driving the carbon market. In Part III: New Ideas in Carbon Capture, we profiled various companies making their mark in CCS. In this final installment, we'll examine the policies that are helping and hindering carbon capture and sequestration.

Part IV: Carbon Policies

The Policy Debate
Should the use of fossil fuels be prolonged, rather than focus on renewable energies such as solar and wind power? There are also doubts about how well the different technologies for storing and capturing carbon will work in the long run. Carbon taxes and cap-and-trade, would also have to be implemented in more countries. The debate will be an intense one.

Gas and wind power are growing fast. And solar power is seen as one of the strongest candidates to become one of the most common energy source in the future. CCS would not bring any climate benefits to the table compared to those energy sources. But there is much at stake and the clean coal technology would, if done correctly and on a large scale, make it possible to make the transition from fossil fuel to renewable energy more of a slide than a jump.

The companies that put CO2 in the ground today might not exist in the future, which is why it is important to create both regulations and standards that could survive over time. It's also a very important factor for companies investing in the technology. They need to know who's going to be responsible if something happens. It is possible that there will be some kind of fund for managing those responsibilities. For every ton of CO2 one injects in the ground one would need to contribute a certain amount to the fund. If something goes wrong there will need to be financial resources available to deal with it.

When it comes to developing the technology and putting it to use, the Intergovernmental Panel on Climate Change (IPCC) has developed a set of guidelines. The guidelines regulate how to inventory green house gases in every sector. And in 2006 the IPCC updated the guidelines with a plan for how to deal with CCS.

The Cost vs. the Future
The business of CCS is not a "two guys in garage" kind of industry. You need a lot of money and a lot of research. So there's no big startup industry connected to it.

"The projects are huge, a couple of billion dollars to build a plant. The insurance industry has developed insurance for this kind of industry. But it's very unlike solar energy where there's a huge potential if you come up with the most efficient solar cell," said Sally Benson, Director of the Global Climate & Energy Project (GCEP) at Stanford University.

But it could be beneficial to have more of a startup-mentality going into capture technology. The notion of carbon capture was not even heard about 15 years ago even though there were people doing research within the field. And it's also a question of humans surviving on the planet earth, which one might think could be worth a reasonable amount of money.

    We need to be thinking about the least expensive way to take carbon out of the atmosphere with off peak wind and solar power. pay for the power with realistically priced carbon credits.

    Rather than try and sequester CO2 after the coal has been burned for its energy content we could just leave it in the ground, and get the energy another way. Wind and solar have been suggested as substitutes, but the intermittency problem has no viable solution at this time. People championing wind and solar blow off the problem of intermittency the same way coal advocates blow off sequestration as something that they will solve mañana. This putting off the hard problems to the future is now killing the “hydrogen economy”, which is floundering in the same problems they had at the start.

    A solution may be waiting in the wings in the form of LFTR a new, well its been around for forty years, reactor, but it has had no advocacy. Using a fuel in the form of a liquid fluoride it has the capability burn Thorium a plentiful material, and produce very little waste, about 35 times less that current reactors. LFTR uses about 5% of the steel and concrete that wind machines use, and can run continuously for 50 or more years without shutting down for refueling. A proof of concept plant could be built in about 7 year, and production units in about ten. This reactor because of its small size, and high temperature operation could produce electricity cheaper than coal. With coal plants producing electricity at a higher cost than LFTRs coal and natural gas produced electricity would disappear.
