OpEd: What India and Pittsburgh Have In Common

I think we all live with some level of tunnel vision. We live locally and too often are unaware of what is going on in the wider world despite our access to the reportage of world events.

 

I thought about my own tunnel vision of the wider world when I did my typical Saturday morning thing: got a cup of coffee from my local Starbucks and read in the New York Times the story: India, Once a Coal Goliath, Is Fast Turning Green.

 

The gist of the story is that India WAS planning on building a whole lot of coal-fired plants but are cancelling many of them because (a) their current plants are operating at only 60% capacity and (B) they are relying more on renewables such as solar power.

 

India, so says the story, is also decreasing its annual coal production from 660 million tons to 600 million tons -- down 10%.

 

Clearly, the world is embracing renewable energy technology. It appears to be making sense in India. It even makes sense to the mayor of Pittsburgh in the U.S. In another story, it says that  Pittsburgh already has 13,000 jobs in the renewable energy industry. Says the story, "Pittsburgh today is increasingly rebuilding around greener medical complexes, research university and tech offices." Less need for coal, for sure.

 

I haven't been to Pittsburgh since I worked for Eaton Corp. as a field engineer about 20 years ago. And I have yet to visit India. But this morning over a cup of coffee at my local Starbucks, my world view just got a wee bit bigger.

    Interesting perspective, but there are other issues driving power in India. Agreed, they are reducing coal power, not so much to be Green, but because they do not have the power distribution infrastructure…

    Don, I think you're right. Accompanying the story, was a picture of a solar panel on top of a man's home. Perhaps that's the only way from him to get power; the story didn't say. But India is indeed a…

    The inverters for appliances in RC (campers) in the US are fairly efficient and common so I shouldn't be surprised that solar cells can be used to feed them for appliance power and lighting in developing…

    The solar v xxx power debate will be an interesting thing in the future.

     

    There was a very good program on National Geographic regarding an Indian based organisation Global Himalayan Expedition (GHE) using volunteers to provide 'micro grid' power to a remote monastery and village in the Himalayas that had no electricity.

    The current lighting ranged from none to candles or other burning items, and the light quality was poor.

    The fuel was trekked in as there were no roads.

     

    They used solar to charge storage batteries which then provided power to LED lights, and was run in 12v for safety.

     

    Watch IEEE Smart Village Volunteers in Action on National Geographic - IEEE - The Institute

    IEEE Smart Village Helps Locals Harness the Himalayan Sun - IEEE - The Institute

    Breakthrough - National Geographic Channel       Power to the People

     

     

    Using Solar or Wind power for generation is fine, but you still need a baseline generation system to cater for cloudy or still days.

    The use of storage batteries is the current cheapest solution, but has limitations and loss of efficiency.

     

    In the meantime these micro-grids are an alternative when there is no power infrastructure or the cost to extend it makes it uneconomic.

    Shabaz,

     

    The Independent article is interesting. I shouldn't be surprised, but I was. I think in the US my perceptions have been skewed by US culture and politics. Too often we think of power as a 1-source resource. But the decentralized power grid is the way of the future with all the power optimization and data analytics making it happen.

     

    I caught this article on the Financial Times: https://www.ft.com/content/e230d280-15e2-11e6-b197-a4af20d5575e

    Look at all the wind power purchases by Google!

    There was a short but interesting article in the news today,

    Solar, wind and nuclear power each provide more electricity than gas and coal combined for first time | The Independent

    apparently yesterday for a period of time energy generated by renewables alone accounted for 50.7% of UK demand, i.e. surpassing coal/gas/nuclear.

    The period of time was possibly not long though!

    The 50.7% was broken down into the following power levels:

    wind: 9.5GW

    solar: 7.3GW

    biomass and hydro: 1.9GW

     

    Of the remainder 49.3%,

    nuclear: 8.2GW

    gas: 7.2GW

    coal: zero

    other (not sure, could be imports?): 2.8GW

     

    I wonder if the national energy organizations have live plotting of this data, or an API. It would be an interesting thing to see. I will ask National Grid in the UK if I can find an e-mail address.. they seem to only address enquiries by letter, not e-mail..

    That was a great video to watch. I'd not heard of molten salts for energy storage, but I found a PDF from University of Alabama, where they mention that the salts they are designing that can have a melting point of around 89-124 degrees C, and energy storage of the order of 1000 megajoules (MJ) per meter cubed, and storage efficiency of 93%!

    Also this Thermal Energy Storage PDF looks interesting although I've only scanned briefly through it so far.

    The inverters for appliances in RC (campers) in the US are fairly efficient and common so I shouldn't be surprised that solar cells can be used to feed them for appliance power and lighting in developing areas of the world.

     

    What really excites me is the renewable energy storage designs. This is about using molten salts for energy storage in a heat exchanger process:

    Of course, the above is beyond the scope of individuals in the developing world, but I think renewable energy storage is the stealth technology that will fundamentally change the world if it can be pulled off on a global scale.
