What it Takes

An extra-ordinary challenge… an extra-ordinary solution.

Requisite Technology Attributes

  • 1 CONTINUOUS
  • 2 HEAT-DRIVEN
  • 3 LOW TEMP
  • 4 CONCENTRATED
1 CONTINUOUS

Continuous vs. Batch

Always be… capturing.

Efficient, affordable chemical processes are Synonymous with high-capacity factors.

That means a DAC system must always be loading CO2, and always be unloading CO2.

Batch processes fail to deliver, Holocene does.

2 HEAT-DRIVEN

Heat vs. Electrically Driven

Regeneration – or the release of CO2 in a DAC process – comprises the majority of energy needs.

For this reason, that energy must be cheap.

Heat – a less refined form of energy than electricity – will always cost 2-5x less than electricity.

Meaning heat-driven processes = Lower Costs.

3 LOW TEMP

Low vs. High Temperature

All heat is not created equal.

This maxim holds true for operating and capital costs, along with system efficiency and availability.

Low temperatures – roughly 100 degrees Celsius, or boiling water temperatures – are cheap and abundant.

High temperatures – or 700 to 900 degrees Celsius – are not.

4 CONCENTRATED

Concentrated vs. Diffuse Delivery

Think about boiling a pot of pasta.

To heat the pasta, you first had to heat lots of water.
But the water is not the product, the pasta is.

In DAC, highly concentrated energy delivery is key to prevent energy waste. CO2 should be 5-10% of the bulk.

For Holocene, it is. For others, it’s not

Requisite Market Attributes

1Low-Cost, Accesible Financing

DAC plants are capital intensive, and the cost of capital (a.k.a. debt) can meaningfully increase total costs – ranging from $10 – 50 per tonne-CO2.

2Clean, Cheap, Abundant Energy

Energy costs can be as much as 20-50% of total removal costs. Sourcing low cost (<$0.03/kWh) energy that does not hurt net negativity is paramount.

3MATURE, READY SUPPLY CHAINS

Supply chains – specifically key equipment such as compressors, tanks, and separation units – must be off the shelf & available to avoid deployment delays.

4Scale, Scale, And More Scale

In comparable industries (chemicals), the difference between 1K and 1Mn (1000x) tonne plants can be 20-50x in unit costs. Scale matters in DAC.
