List of technologies

ASPI’s Critical Tech Tracker project started in 2021. After extensive consultations with stakeholders in Australia, and across multiple countries, we decided to use the Australian Government’s  ‘List of Critical Technologies in the national interest’ as our technology definitions for this project (with some very minor tweaks made to technology descriptions).

This list is hosted by Australia’s Department of Industry, Science and Resources (DISER) and can be accessed here. Of the 63 technologies on this Australian Government list we included 44 technologies in phase 1 of this project. The definitions of these 44 technologies have been included below (please visit the DISER website for the complete list and all definitions).

We recognise that technology definitions can evolve over time and in future phases of this project we will consult closely with stakeholders as we add new technologies. Our intention is for the Critical Tech Tracker to remain a useful, global and freely available public policy tool for many years to come.

What are critical technologies?

Critical technologies can be defined as current and emerging technologies with the capacity to significantly enhance, or pose risk to, a country’s national interests, including a nation’s economic prosperity, social cohesion, and national security. This is the Australian Government’s definition, and it’s a good one that holds relevance for all countries.

Today, critical technologies are the focus of geopolitical and strategic competition and our understanding of the critical technology ecosystem – from how to ensure reliable access, the current trajectory of technology development and where the next breakthroughs will occur (and in what) – is too limited. It’s important that we seek to fill this gap, and we hope this project will make a contribution, so we don’t face a future in which one or two countries dominate new and emerging industries (something that occurred in 5G technologies) and so countries have ongoing access to trusted and secure critical technology supply chains.

Advanced materials and manufacturing

Applications for supercapacitors include regenerative braking, smartphones and personal electronic devices, grid energy storage and defence.


Post-quantum cryptography

Mathematical techniques for ensuring that information stays private, or is authentic, that resist attacks by both quantum and non-quantum (i.e. classical) computers. The leading application for post-quantum cryptography is securing online communications against attacks using quantum computers. Because quantum computers can efficiently solve the ‘hard’ mathematical problems we currently rely on to protect online communications, Australia needs post-quantum cryptography to ensure communications stay secure once quantum computers are available.
