Batteries – energy storage

Within the infrastructure sector (energy), one of the most critical pieces of the puzzle is battery storage. There are a multitude of technologies developing, though it’s not yet clear whether any will replace lithium batteries and solve the issue of limited resources such as lithium.  A recent development in battery storage is a concentrated solar thermal project which is being backed by the likes of Chevron.  This has the benefit of not requiring rare earths to act as inputs into the battery and hence is able to decouple growth and the use of resources given it uses minimal resources.  The premise is that mirrors superheat specialized solar cells, the heat is captured and stored in water, which can then be released to boil ammonia to spin a turbine hours or days later, overcoming the intermittency of renewables. If you want to increase storage, you make the hole which stores the water bigger, without using precious metals etc:

Another technology I have recently read about is a gravity energy storage system using recycled materials:

In their initial stages, these projects need government grants and subsidies or large businesses willing to spend material amounts of money on R&D to perfect and commercialise the solution.

Interesting that you have brought the battery sector. The company I work for have a new product  that came from the innovation process, is a battery made from a tree. 

This development for sure had to incorporate all 4Ps  as I see this as a new radical and disruptive product, we look for the full usage of what a tree can offer, developing  possibilities that come in hand with  a decarbonized society.  The aim for finding bio-based solutions was the drive for this innovative product, being a pulp producer, we have the lignin as a side stream product from the Celulose production, we have several possibilities of usage as this is a binder and one of the renewable sources of carbon. We have produced from the lignin, hard carbon powder, card carbon electrode and now battery.  Read more.

All of these tells me that we have brought new possibilities to the market, substituting fossil products to bio-based ones, so adding the 4Ps to this innovative solutions. Enabling electrification made from a tree, a sustainable type.

This product is a lignin anode material and we have recently announced a partnership with an European battery cell producer to scale up  and became the first industrialized battery featuring anode sourced entirely from European raw materials, lowering both the carbon footprint and the cost.
