Put simply: if we want to decarbonise the world, we have to electrify it.

Decarbonisation through electrification takes four forms, each of which is critical:

• Decarbonisation of the electricity supply. Here, Exawatt’s focus is on solar photovoltaic (PV) technology, which we believe will, in most parts of the world, become the lowest-cost source of electricity. If the electricity supply is not decarbonised, the rest doesn’t matter
• Electrification of processes and systems. Exawatt’s primary focus in this area is on electric vehicles (EV) and on electrified transport
• Decarbonisation of energy transmission, whether at grid level or within specific systems (e.g. in an EV inverter, which converts DC power from the EV battery into three-phase AC power to drive the motor)
• Decarbonisation of energy storage, including lithium-ion batteries, sodium-ion batteries, green hydrogen and green ammonia

In each case, Exawatt takes a similar analytical approach, with a focus on mapping and modelling supply chains back to their sources and developing accurate manufacturing cost and performance models that allow us to forecast “should costs” for each technology with a high degree of accuracy.
