Drax To Pilot More Pioneering New Carbon Capture Technology

The title of this post, is the same as that of this press release from Drax.

This is the first paragraph.

Renewable energy pioneer Drax has partnered with the University of Nottingham and Promethean Particles to trial a pioneering new bioenergy with carbon capture and storage (BECCS) process at its North Yorkshire power station.

Normally, carbon capture from the flue gas of a power station uses a liquid solvent, which dissolves the carbon dioxide.

However, the process that Drax are trialling, uses porous compounds called metal–organic frameworks (MOFs) to absorb the carbon dioxide.

This page on the Promethean Particles web site described how their carbon-capture works.

Traditional solvent-based carbon capture systems require a significant amount of energy to regenerate the carbon-capturing material. In power generation applications, estimates put this energy penalty at up to 35% of the power station’s output. Metal-organic frameworks (MOFs) capture carbon mainly through physical, not chemical means. This “trapping” process requires lower energy inputs to regenerate the MOFs and can therefore help achieve more energy-efficient carbon capture. By using MOF-based carbon capture, more of the power generated can go where it was intended, lowering the price of energy for consumers and CAPEX for the power generators.

Note.

  1. It is a physical rather than a chemical process.
  2. It is more energy efficient than traditional carbon-capture.

This Drax graphic from the press release, shows how this process can be incorporated into a power plant..

Note.

  1. The trial will last for two months and will be hosted within Drax’s BECCS incubation hub at its North Yorkshire Power Station.
  2. Metal Organic Frameworks are a unique class of solid sorbents offering lower operational costs and reducing potential environmental impacts.

Work to build BECCS at Drax could get underway as soon as 2024, with the creation of thousands of jobs.

Fifty years ago, I spent several months at ICI looking at the mathematics of different numbers and sizes of vessels of in a proposed chemical plant, to optimise the cost of the plant.

  • I suspect a similar analysis could be applied to this process.
  • It would surely be very suitable for Drax, whose main power station has four units fuelled by biomass and another fuelled by natural gas.
  • Are two columns containing MOF, the optimum number?
  • The calculation could involve a lot of permutations and combinations, which I’ve used to advantage for over fifty years.

I will follow this trial with interest.

Conclusion

This is another application of advanced physics and chemistry.

If Promethean Particles ever decide to go the crowdfunding route, I would look seriously at a small investment.

  1. While this experiment is commendable, and leaving aside the fact that their energy is considered renewable if the first place, I find it hard to have any nice words for Drax after reading what the neighbours of their pellet production plant have to put up with.
