Study Of CO2 Flow Via North Sea Geology Will Develop Tools For Storage Sites

Published

on

Scientists at the University of Strathclyde have secured funding for a four-year project which will enable them to study the ability of complex rock strata below the North Sea which will securely trap carbon dioxide emissions (CO2).

Their findings will help to provide the tools for selecting the most suitable CO2 storage sites as part of the large-scale development of carbon capture and storage, a key climate change technology. These tools could also greatly expand the potential for CO2 storage worldwide.

The study will look at how CO2, when injected into rocks deep below ground, could migrate upwards through the overlying strata, or overburden. The greenhouse gas can become trapped by dissolving into water-filled spaces between the rock grains. In more complex geology, where the fluids flow through complex pathways, there may be more potential for trapping CO2 as it rises, thereby minimising the risk of it escaping to the surface.


However, fault zones cutting geological layers could potentially provide shortcuts past the layers where CO2 could be trapped. The project team will investigate how the faults and rock strata interact to change the pathways for CO2 flow through the overburden.

The researchers from Strathclyde, an SCCS partner institute, will work with fellow scientists from the Universities of Cambridge and Imperial, and the British Geological Survey as part of a larger research project funded by Natural Environment Research Council (NERC).

Professor Zoe Shipton, University of Strathclyde, who will lead the fault zone study, said: “The rock types found within fault zones will change depending on the rocks that they cut. By understanding how the fault rock types influence mechanisms such as capillary trapping, dissolution of CO2 in water and migration pathways, our work can guide strategies for quantifying and reducing the risks of CO2 leakage from geological storage sites.”

We will construct simplified models of flow along layered strata with cross-cutting faults, alongside our partners’ laboratory analogue experiments, in order to constrain the effect of geological complexity on the fate of CO2 leaking from a subsurface storage site.


The researchers will also look at real-life examples of CO2 storage – for example, Norway’s Sleipner project in the North Sea – to test their findings.

The UK is geologically well placed to implement offshore CO2 storage, with many potential reservoirs in the geology beneath the UK’s North Sea.

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.”
