CO2 Fingerprint Discovery allows Safe Storage of Greenhouse Gas

Scientists have found an inexpensive way to help monitor the safe storage of carbon dioxide captured from power stations and industrial sources.

Their work will help the development of Carbon Capture and Storage (CCS) technology, in which CO2 from power stations and industrial sources is held deep underground, to prevent emissions of this greenhouse gas from contributing to climate change.

In the first study of its kind, researchers have discovered that CO2 captured from power stations and industrial sites will have a distinctive chemical fingerprint, depending on its source. This allows it to be distinguished from other CO2 present near storage sites, such as groundwater or naturally occurring CO2 given off by plants and bacteria.

This means that CO2 being injected deep underground does not need to have expensive chemical tracers added, in order to monitor that it is effectively contained.

Researchers from the University of Edinburgh found that the natural fingerprint of captured CO2 depends on the fuel producing the gas – such as coal, oil, natural gas or biomass – and the technology being used to capture it before it is injected for underground storage.

By comparing the chemical fingerprints in the captured CO2 with those in geological storage reservoirs and drinking water aquifers, they have been able to show that the fingerprints can be easy to identify and distinguishable from natural sources of CO2.

The study, published in Environmental Science and Technology, was supported by the Engineering and Physical Sciences Research Council.

Dr Stephanie Flude, of the University of Edinburgh’s School of GeoSciences, who led the study, said, “Defining these natural fingerprints in captured CO2 will simplify the monitoring of geological CO2 storage sites.

This method is inexpensive as it removes the need to add additional expensive artificial tracers to the CO2 being stored.

Dr Stuart Gilfillan, also of the School of GeoSciences, the study co-ordinator, said, “There has been a pressing need to identify a means to distinguish CO2 to be stored from that already in the subsurface to help CCS deployment. Our study shows that natural fingerprints in the captured CO2 are unique and depend on the capture technologies being used. This paves the way for natural fingerprints to be used to track the CO2 once it is injected underground for storage.”

A Good Look At How Homes Will Become More Energy Efficient Soon

energy efficient homes

Everyone always talks about ways they can save energy at home, but the tactics are old school. They’re only tweaking the way they do things at the moment. Sealing holes in your home isn’t exactly the next scientific breakthrough we’ve been waiting for.

There is some good news because technology is progressing quickly. Some tactics might not be brand new, but they’re becoming more popular. Here are a few things you should expect to see in homes all around the country within a few years.

1. The Rise Of Smart Windows

When you look at a window right now it’s just a pane of glass. In the future they’ll be controlled by microprocessors and sensors. They’ll change depending on the specific weather conditions directly outside.

If the sun disappears the shade will automatically adjust to let in more light. The exact opposite will happen when it’s sunny. These energy efficient windows will save everyone a huge amount of money.

2. A Better Way To Cool Roofs

If you wanted to cool a roof down today you would coat it with a material full of specialized pigments. This would allow roofs to deflect the sun and they’d absorb less heat in the process too.

Soon we’ll see the same thing being done, but it will be four times more effective. Roofs will never get too hot again. Anyone with a large roof is going to see a sharp decrease in their energy bills.

3. Low-E Windows Taking Over

It’s a mystery why these aren’t already extremely popular, but things are starting to change. Read low-E window replacement reviews and you’ll see everyone loves them because they’re extremely effective.

They’ll keep heat outside in summer or inside in winter. People don’t even have to buy new windows to enjoy the technology. All they’ll need is a low-E film to place over their current ones.

4. Magnets Will Cool Fridges

Refrigerators haven’t changed much in a very long time. They’re still using a vapor compression process that wastes energy while harming the environment. It won’t be long until they’ll be cooled using magnets instead.

The magnetocaloric effect is going to revolutionize cold food storage. The fluid these fridges are going to use will be water-based, which means the environment can rest easy and energy bills will drop.

5. Improving Our Current LEDs

Everyone who spent a lot of money on energy must have been very happy when LEDs became mainstream. Incandescent light bulbs belong in museums today because the new tech cut costs by up to 85 percent.

That doesn’t mean someone isn’t always trying to improve on an already great invention. The amount of lumens LEDs produce per watt isn’t great, but we’ve already found a way to increase it by 25 percent.

Maybe Homes Will Look Different Too

Do you think we’ll come up with new styles of homes that will take off? Surely it’s not out of the question. Everything inside homes seems to be changing for the better with each passing year. It’s going to continue doing so thanks to amazing inventors.

IEMA Urge Government’s Industrial Strategy Skills Overhaul To Adopt A “Long View Approach”

Published

on

IEMA, in response to the launch of the Government’s Industrial Strategy Green Paper, have welcomed the focus on technical skills and education to boost “competence and capability” of tomorrow’s workforce.

Policy experts at the world’s leading professional association of Environment and Sustainability professionals has today welcomed Prime Minister Teresa May’s confirmation that an overhaul of technical education and skills will form a central part of the Plan for Britain – but warns the strategy must be one for the long term.

Martin Baxter, Chief Policy Advisor at IEMA said this morning that the approach and predicted investment in building a stronger technical skills portfolio to boost the UK’s productivity and economic resilience is positive, and presents an opportunity to drive the UK’s skills profile and commitment to sustainability outside of the EU.

Commenting on the launch of the Government’s Industrial Strategy Green Paper, Baxter said today:

“Government must use the Industrial Strategy as an opportunity to accelerate the UK’s transition to a low-carbon, resource efficient economy – one that is flexible and agile and which gives a progressive outlook for the UK’s future outside the EU.

We welcome the focus on skills and education, as it is vital that tomorrow’s workforce has the competence and capability to innovate and compete globally in high-value manufacturing and leading technology.

There is a real opportunity with the Industrial Strategy, and forthcoming 25 year Environment Plan and Carbon Emissions Reduction Plan, to set long-term economic and environmental outcomes which set the conditions to unlock investment, enhance natural capital and provide employment and export opportunities for UK business.

We will ensure that the Environment and Sustainability profession makes a positive contribution in responding to the Green Paper.”
