I have been familiar with EFL since about 2002 and have since re-entered back in the spring. I originally sold out because development times were taking forever and EV's seemed to be waffling on the edge.

It is good to see EFL diversify into alternative, very reasonable and in demand projects such as large scale stationary storage. The bottleneck of green energy production and sticking point to de-centralizing power generation. Batteries "are" the holy grail for many of these applications.

Genew .......To your point of Li-on phosphate. When I was still invested yrs ago, I had a conversation with PH about the Purolator project. After 2 yrs of waiting for some kind prototype road testing, I was shocked to find out they had only just completed changing the battery chemistry to, .... Li-on phosphate. That was probably 6 yrs or so ago if memory serves me correct.

It was then good to see the video from Dalhousie (I think) on finding methods to predetermine battery life with differing chemistries. Interestingly, Li-on phosphate was one of the better performing designs.

Since then, it is good to see the Purolator EV's finally on the road (in Toronto I believe). These are big units almost as big and heavy as a cube van. Haven't done any digging to see their long term performance.
