The trouble with some renewable energy sources (eg wind power) is that they are unpredictable and unreliable. So without a reliable means of storing the energy they generate they can only be on limited use. But maybe new developments in Japan are beginning to address this and might improve the effectiveness of micro-generation on Dartmoor.

There’s a new product being cautiously released in Japan.

It is not a fuel cell, as the headline claims, nor is it seemingly a dramatic new storage medium. It is more interesting than that. It seems to be one of the cogs needed to create a smart grid.

It uses old-tech – possibly refined – of lithium-ion batteries for storage. It then releases the stored electricity whilst taking into account the house’s generating methods, power needs and the needs of the national grid.

It can release house-generated stored power when demand on the national grid is peaking, and take advantage of power from the national grid when there is low demand.

As claimed, this could have the affect to ‘reduce the overall volume of power consumption’.

This seems to be the first semi-commercial release for real world testing, and there will be still a period of refinement. Plus of course, the Japanese market is where most Japanese products fail (very fussy consumers as well as being early adopters) and it is used as a testing ground for that reason.
