Climeworks Presents CO2 Capture From Air At COP 22

The COP22 Climate Change Conference in Marrakech marks the very first “large-scale technical-solutions conference” for senior delegates by UNFCCC and experts of technology of the 196 states.

Focus during the three-days “Low-Emissions Solution Conference” is a presentation by 20 chosen cleantech start-ups that introduce their scalable technologies. Climeworks will show its efficient solution to filter CO2 from ambient air and share the potential for climate protection.

The Climeworks CO2 Direct Air Capture (DAC) technology is based on a cyclic capture-regeneration process and a novel filter. During the capture process, atmospheric CO2 is chemically bound to the surface of the filter. Once the filter is saturated, the CO2 is released by heating it to a temperature of about 100 degrees Celsius, thereby delivering high-purity gaseous CO2. The CO2-free filter can be re-used for thousands of capture-regeneration cycles. DAC allows a significant emissions reduction through the production of low-carbon fuels and eventually enabling negative emissions when combined with a permanent carbon storage solution.

The Climeworks founders have set themselves an ambitious goal: capturing one percent of global CO2 emissions by 2025. Simply by changing the number of modules, Climeworks’ DAC technology can be freely scaled to meet the demands of any application and has a carbon removal potential that is relevant for achieving climate targets agreed upon in the Paris Agreement.

Climeworks’ products have several commercial applications: In the short-term the company targets large merchant markets by selling air-captured CO2 to customers like greenhouse operators or the beverage industry, which currently receive their CO2 primarily as an industrial waste product and often from the combustion of fossil fuels.

In the mid-term, Climeworks seeks to close the carbon cycle by providing atmospheric CO2 for the production of low-carbon fuels, which allows large-scale storage of renewable energies and which further allows to address CO2 sources which are otherwise hard to capture, e.g. emissions from the past or mobile sources. By that reason, the company is in a close partnership with carmaker Audi.

In the long-term and in combination with storage technology, DAC is one of only few technologies with the potential to capture and permanently remove several gigatons of atmospheric CO2 per year. The usage of so-called Negative Emission Technologies (NET) is considered necessary in more than 85% of IPCC climate scenarios consistent with the goal of limiting global warming to 2 degrees Celsius.

Most of our focus on technological development to lessen our environmental impact has been focused on cleaner, more efficient methods of generating electricity. The cost of solar energy production, for example, is slated to fall more than 75 percent between 2010 and 2020.

This is a massive step forward, and it’s good that engineers and researchers are working for even more advancements in this area. But what about technologies that reduce the amount of energy we demand in the first place?

Though it doesn’t get as much attention in the press, we’re making tremendous progress in this area, too.

New Technologies to Watch

These are some of the top emerging technologies that have the power to reduce our energy demands:

  1. Self-driving cars. Self-driving cars are still in development, but they’re already being hailed as potential ways to eliminate a number of problems on the road, including the epidemic of distracted driving ironically driven by other new technologies. However, even autonomous vehicle proponents often miss the tremendous energy savings that self-driving cars could have on the world. With a fleet of autonomous vehicles at our beck and call, consumers will spend less time driving themselves and more time carpooling, dramatically reducing overall fuel consumption once it’s fully adopted.
  2. Magnetocaloric tech. The magnetocaloric effect isn’t exactly new—it was actually discovered in 1881—but it’s only recently being studied and applied to commercial appliances. Essentially, this technology relies on changing magnetic fields to produce a cooling effect, which could be used in refrigerators and air conditioners to significantly reduce the amount of electricity required.
  3. New types of insulation. Insulation is the best asset we have to keep our homes thermoregulated; they keep cold or warm air in (depending on the season) and keep warm or cold air out (again, depending on the season). New insulation technology has the power to improve this efficiency many times over, decreasing our need for heating and cooling entirely. For example, some new automated sealing technologies can seal gaps between 0.5 inches wide and the width of a human hair.
  4. Better lights. Fluorescent bulbs were a dramatic improvement over incandescent bulbs, and LEDs were a dramatic improvement over fluorescent bulbs—but the improvements may not end there. Scientists are currently researching even better types of light bulbs, and more efficient applications of LEDs while they’re at it.
  5. Better heat pumps. Heat pumps are built to transfer heat from one location to another, and can be used to efficiently manage temperatures—keeping homes warm while requiring less energy expenditure. For example, some heat pumps are built for residential heating and cooling, while others are being used to make more efficient appliances, like dryers.
  6. The internet of things. The internet of things and “smart” devices is another development that can significantly reduce our energy demands. For example, “smart” windows may be able to respond dynamically to changing light conditions to heat or cool the house more efficiently, and “smart” refrigerators may be able to respond dynamically to new conditions. There are several reasons for this improvement. First, smart devices automate things, so it’s easier to control your energy consumption. Second, they track your consumption patterns, so it’s easier to conceptualize your impact. Third, they’re often designed with efficiency in mind from the beginning, reducing energy demands, even without the high-tech interfaces.
  7. Machine learning. Machine learning and artificial intelligence (AI) technologies have the power to improve almost every other item on this list. By studying consumer patterns and recommending new strategies, or automatically controlling certain features, machine learning algorithms have the power to fundamentally change how we use energy in our homes and businesses.

Making the Investment

All technologies need time, money, and consumer acceptance to be developed. Fortunately, a growing number of consumers are becoming enthusiastic about finding new ways to reduce their energy consumption and overall environmental impact. As long as we keep making the investment, our tools to create cleaner energy and demand less energy in the first place should have a massive positive effect on our environment—and even our daily lives.
