Big battery technology - large storage for renewable energy wind and solar

Savings from oil and coal importation

More and bigger giant battery storage facilities for outputs of solar and wind energy are being built in California:   one a 300 megawatt and  another 100 megawatt.  The storage facilty will  be enough to power 300,000 homes for four hours, in the evening or when demand outstrips supply.  They will be commissioned in 2021  (this year)

Longer lasting batteries by simply adding sugar to the electrolytes

Savings from oil and coal importation

It has been found in Monash Energy Institute  that adding sugar to the electrolytes can make batteries last longer, be lighter in lithium sulfur batteries   Sugar prevents sulfide from massing at Lithium electrodes.  

There is still much research to refine the  technology and apply to actual production.  

Just a spoonful of sugar

Giant offshore wind turbines

There is much activity in giant offshore wind turbines,    Offshore is better where wind is stronger and more stable.   

The latest projects are huge 853 ft tall,nearly  as tall as Empire State Building with blades length as much as 2x a football filed.   One such project is GEs Haliade x that can generate 30x the electricity being generated of earlier turbines.    as 13 megawatts enough to light up 12,000 homes

Power output of the 10 largest turbines range from 6 to 10 MW.   GEs monster is the biggest

Renewed Interest in renewables after meeting chairman of WEGEN

Savings from oil and coal importation

This post interest on renewable energy was renewed after meeting Mr. Michael Schefeld, the chair of WeGen.   For more than an hour he talked effusively about Renewables in Germany where he comes from, Net Metering (a challenge)   In Germany he  claims a 60%   Renewable acceptance (with solar and wind leading the charge)  He showed me the real time increse in renewable usage.

He described the operations of WeGen (engaged in the  importation of solar panels, controllers and inverters)  I told him about our brief foray into PV and its financing.     I broached the feasibility of working together in this promising field. It has been an interest for the last 20 years.   

We Gen of which he is the chairman, has partnered with the bishops in promoting renewables (PV)  This post observed this to be a unique business model but ultimately financing will be a key component in winning the renewable war.

\He discussed the logic behind the  PV ie of that being close to the user, no infrastructure needed like the grid  (However it occured to this post that batching may be cheaper in communities to have a farm rather than rooftop installation.  

He said that cost of the Solar panels have gone down from $0.40 to only $0.20 (still at P100,,000 per kw)

We planned to meet after the ECQ or MECQ but he  died last week.   He  left a widow whom he endowned with a Filipino Chinese restaurant facing a river connecting Laguna Lake and Pasig River.
