PHE & AVIOXX. Addressing Testpacks FUD.22 Jan 2025 21:27
In response to the misinformation and FUD, titled "PHE & SAF" by the account named Testpack3.
The comments in the post are riddled with misinformation and a clear bias aimed at discrediting my and Bob's report and the credibility of Powerhouse Energy Group (PHE) and Avioxx. Here’s my evidence-based rebuttal addressing each point systematically:
1)"SAF produced must be from non-FF (fossil fuel) based feedstock. Plastic is FF based.”
This statement conflates the origin of plastics with their current state as waste. International regulations, including CORSIA and ReFuelEU Aviation, recognise that waste plastics diverted from landfills meet sustainability criteria as long as they do not contribute to additional fossil fuel extraction. Avioxx and PHE’s technologies align perfectly with these frameworks, as the feedstock (end-of-life plastics) would otherwise decompose in landfills, emitting methane—a greenhouse gas significantly more potent than CO₂.
Fact: Lifecycle analyses consistently show that SAF from waste plastics achieves up to 90% carbon emission reductions compared to fossil-based jet fuel.
2) “Avioxx states that carbon capture would be used in advanced Fischer-Tropsch reactors to produce liquid hydrocarbons.”
Correct. Carbon capture in the Fischer-Tropsch process is a recognised best practice to enhance efficiency and minimise emissions. Avioxx’s use of advanced Fischer-Tropsch reactors demonstrates its commitment to cutting-edge technology and environmental stewardship.
3) “This problem would be negated if the feedstock was bio-mass.”
While biomass is a valid SAF feedstock, it is limited in availability and often competes with agricultural uses. By focusing on waste plastics, PHE and Avioxx avoid these issues, offering a more scalable and sustainable alternative. Moreover, their approach supports the circular economy, turning waste into valuable fuel rather than diverting agricultural resources.
4) “I did ask if a trial with bio-mass feedstock was planned at Bridgend. No reply to date.”
The focus on waste plastics reflects PHE and Avioxx's commitment to addressing the global waste crisis, reducing landfilling, and offering a diversified approach to SAF production. While trials with bio-mass may be valid, they are unnecessary given the robustness of the current waste-to-SAF model.
International Standards and Compliance.
CORSIA and ReFuelEU Mandates: Both frameworks support SAF production from waste-derived feedstocks, provided they meet carbon reduction criteria. PHE and Avioxx’s lifecycle analyses, adherence to ASTM D7566 standards, and use of Fischer-Tropsch synthesis ensure compliance.
Feedstock Flexibility: PHE’s DMG® technology and Avioxx’s Eco-Feed™ system are designed to handle diverse feedstocks, including non-recyclable plastics, agricultural residues, and municipal waste, aligning with global SAF policies.
