"A new report from the Australian Renewable Energy Agency (ARENA) has
highlighted the huge promise of electric vehicles as batteries on wheels,
potentially accounting for a huge amount of low cost energy storage to support
the renewable transition.
The report suggests that new policy should make both V2G (Vehicle to Grid) and
V2H/B (Vehicle to Home and Building) a priority.
“Australia’s EV vehicle fleet will be largest and lowest cost potential storage
resource in our energy transition,” the report says.
“National EV policy should signal that we value V2G and V2H/B as a near term
priority for industry development and we should set out a V2G vision in our
National EV Strategy.”
While renewables will be able to fill most of our energy needs, they are
variable, which means that battery storage will be required as part of the
National Energy Market (NEM) to ensure that people can still use power at all
times of the day.
According to the report, the total storage requirements for the NEM will be
640GWh in 2050. But by 2050, Australia’s EV fleet will have almost 2,400 GWh
capacity, so even if only a fraction of electric vehicle owners had the option
for V2G, it could cheaply provide much of Australia’s energy storage.
“The challenge for Australia is establishing an effective framework to access
the capacity that will already exist in our EV fleet,” the report says."
We have solar panels and a Nissan Leaf and have been wanting to do this for
several years already. I wish our state government would hurry up and copy the
neighbouring South Australian government so we can actually go ahead.
