Roche Axelios - My Current Understanding

ASeq Newsletter • 36 implied HN points • 07 Mar 26
🔬 Science Cost Analysis
  1. Roche’s Axelios can deliver genomes far cheaper than competitors — the headline is $150/genome, but a near‑Illumina quality simplex 30x genome may be around $30, with duplex offered for higher accuracy.
  2. Initial 19‑hour prep times looked concerning, but an SBX‑Fast workflow suggests similar throughput with about a 3.5‑hour prep; final workflows (especially for simplex) aren’t public and prep time could still affect margins.
  3. The system uses small disposable sensor chips that Roche claims can be reused (~20×), so chip cost likely only adds a modest amount (probably under ~$100) to each run rather than being a major cost driver.

Jim Hopf on Dry Cask Cost and Quality

Gordian Knot News • 212 implied HN points • 03 Dec 25
🕹 Technology Cost Analysis
  1. Nuclear quality is defined by the N-stamp, which only shows that a vendor has followed the proper paperwork, not the actual quality of the product. This can lead to issues if the focus is more on paperwork than on the quality itself.
  2. Costs of dry cask storage have dramatically increased over the years due to strict regulations, even though the original systems worked just fine. These regulations can create barriers to innovation and make safe options much more expensive.
  3. Using non-standard materials can pose challenges in the nuclear industry, as regulations often require products to meet unnecessary criteria that don't necessarily improve safety, leading to higher costs and potential quality issues.

The imperfect LCOE and CfD

GEM Energy Analytics • 439 implied HN points • 13 Apr 23
🌞 Climate & Environment Cost Analysis
  1. LCOE is not a reliable measure for wind and solar energy. It can mislead comparisons and decisions about energy costs.
