There's very few publicly listed renewables developers on the ASX now, apart from Origin there's Frontier Energy FHE, Meridian Energy MEZ, Mercury NZ MCY and Infratil IFT, and the last 3 are all mostly operating in NZ.
Battery wise there's Redflow RFX or Australian Vanadium Limited AVL
What you can invest in though is the services companies supplying the engineering, maintenance, data centres, substations, transformers, HV cables etc these projects are using. There's a myriad of those companies such as NEXTDC NXT, Service Stream SSM, Tasmea TEA, Energy One EOL, SRG Global SRG, Worley Limited WOR, Genus Plus GNP.
Plenti PLT provide lending to renewable energy projects.
ClearVue CPV are developing window panes that function as solar panels for greenhouses etc.
LGI limited LGI capture biogas from landfill for onsite power generation and are developing solar fields too.
Sims Limited SGM and Close the Loop CLG are waste recyclers with streams being developed for renewable waste recycling.
It's no surprise either that most of these have very nice looking uptrends...
