[But they're still not addressing:
1) How does the vehicle owner get compensated for the energy supplied
and depreciation to the vehicle battery?
2) When grid-scale batteries are now a cheaper option than fitting extra
hardware in the EV or PHEV, why would a grid operator bother with
intermittent storage which is not within their control? We have had
decades of grid operators disliking intermittent generation, which is
only now being resolved, largely by grid-connected battery storage.
I see value in V1G, V2H (vehicle and house belong to same entity), and
V2B. I just don't see the case for generic V2G. And if the plan for
V2G doesn't include regular use, where's the value justification for the
extra cost?]
Engie, Hitachi and Mitsubishi pilot world’s first vehicle-to-everything tech
April 5, 2018
Integrated energy company Engie, innovation firm Hitachi and automobile
company Mitsubishi Motors partnered on a pilot demonstrating how
electric vehicles can be used to optimise building and grid energy
management.
The pilot was implemented in Zaandam, Netherlands and included linking a
vehicle to everything (V2X) charger to an office building owned by Engie.
A V2X charger enables an EV to charge from the grid, as well as to
discharge energy to meet supply demand on the grid.
Under the pilot, Hitachi provided its V2X charger whilst Mitsubishi
provided its Outlander PHEV SUV.
The V2X was connected to the building’s energy supply systems, the main
grid and an onsite solar generator. The integration allowed excess
energy generated from solar to be stored in the battery of the electric
vehicle.
The EV was used as an energy storage platform and as an emergency power
supply system providing energy to meet the building’s energy
requirements during low solar energy generation or when Engie wanted to
avoid high tariffs on the main grid during peak periods.
The three parties claim vehicle to building technology would help
companies reduce energy costs and global carbon emissions through
improved energy management.
Service providers such as Engie are predicted to have buildings and
transport accounting for 75% of total carbon emissions, according to a
statement.
Ram Ramachander, Chief Digital Officer at Hitachi Europe, said: “…IoT
and digital capabilities can help customers make buildings
energy-neutral, increasing their energy efficiency and reducing costs,
by optimising EV charging infrastructure. Our technology can also help
to create new business cases across the EV value chain, including
vehicle to grid technology, which enables flexibility with their energy
distribution”.
Hans Boot, COO at ENGIE Services Netherlands, added: "This project
provides a powerful demonstration of the outstanding effectiveness of
energy storage technology. This charger exceeds smart charging as we
know it and is basically the first real ‘smart grid charger’..."
