Hachiko Energy
FeaturedAustralia
Batteries are valuable because they provide flexibility, responding faster than other energy technologies, and help maintain grid stability by turning on and off in fractions of a second., Software contributes through improved grid performance, efficient integration of diverse energy sources, simulation and modelling of energy options, optimisation of building energy use (particularly HVAC systems), and guiding organizations in delivering emission reduction goals through accurate measurement and reporting.

Renewable Metals
FeaturedAustralia
The batteries powering the energy transition contain critical minerals — lithium, cobalt, nickel, manganese — that are energy-intensive to mine, geopolitically concentrated, and increasingly in demand.
Yet when those batteries reach the end of their life, most recycling processes either burn off the value through energy-intensive smelting or recover it through acid-based hydrometallurgy that generates large volumes of sodium sulfate waste — trading one problem for another.
Renewable Metals takes a different approach. Founded by Australian metallurgists with decades of experience extracting battery metals from ore bodies, the company draws on Australia's distinctive tradition of alkali-based metallurgy — developed for nickel and cobalt refining and largely absent in the rest of the world — to recover critical minerals through a world-first alkali recycling process.
The result recovers almost all the lithium, nickel, cobalt, copper and manganese from end-of-life batteries, works across all major chemistries including LFP, requires no pre-processing to black mass, and produces none of the chemical by-products that plague acid-based alternatives. Recycling is the lowest-carbon source of critical minerals — and Renewable Metals is building the process that makes it commercially viable.
