India to explore clean coal technology: Goyal


India is planning to go for clean coal technology as the dry fuel will be mainstay in India's energy mix, Power Minister Piyush Goyal on Wednesday said, adding it will also help in country's efforts towards addressing environmental concerns. "We will look for technologies for clean coal as this will be the mainstay in India's fuel mix even as we strive to address climate concerns," Goyal said here while addressing at Indo-Japan Energy Forum organised by the CII.

He said, "Strong bilateral relations between Japan and India to be further strengthened in the areas of energy cooperation and building smart cities." India has doubled its coal thermal capacity since 2007 and looking towards greater emphasis on clean coal technologies as coal will continue to be the predominant fuel.

Emphasising on the importance of coal, Japanese Minister of Economy, Trade and Industry, Yoichi Miyazawa said, "Coal is geographically available and will remain an important energy source." Miyazawa further emphasised on how innovation in technology will help both countries fight climate change and bring about greater economic growth. Commending the NDA government for its emphasis on infrastructure and energy, he said, "India is now drawing attention from the rest of the world and will emerge as the third largest economy by 2035. The country's energy consumption is likely to double. To reduce the reliance on energy imports, the investments in energy infrastructure are timely."

Elaborating the challenges being faced by both countries he said, "Economic efficiency, energy security and environment are common policy issues that the countries are grappling with. The possibilities for cooperation between the two countries in clean coal are enormous. The Government of Japan is keen to expand energy cooperation with India." Echoing similar views, Goyal said, "India and Japan can collaborate on the clean technology side. Japan has realised it is important to have thermal coal and is looking at putting in place 7200 MW over the next five years." "We are looking at doubling our generation from one trillion units to two trillion and our reliance on coal will continue.

To improvise on the coal technology, both countries can work together and help to assuage the concerns on climate. We will be happy to take up the best technology to bring down the impact of coal on the environment," he added. Elaborating on renewable energy, Goyal further said, "India has set a 175 GW target for renewable energy and this will happen in the next five years. To achieve the targets, the minister said, "We are looking at innovative financing models. We are engaging with states to expand rooftops in a big way."

Fully agreed we have a lot of things to think about & what happened 70 years ago is not our concern

Except only that it was YOU who brought the topic of history by saying that India doesn't have similar complaints. I was talking about Chinese and Japanese relations at that time.

Ramjet ,

This thread is about Indo-Japanese constructive developments on coal industry and related fields. This thread is not about China , Sino-Japanese relations, Indo-Chinese relations. Please discuss only on issues relating to Indo-Japanese constructive developments in relevant fields.

Thanks.

To be honest, everything else really is just work in progress and given enough time it will get done. The biggest problem I had with Indian grid is that coordination is done by multiple agencies rather than one. It is rather inefficient and sometimes let politic get into what should a purely mathematically activity.

Solar panel over water canal is an interesting idea. I am not an expert on Solar panel construction. I guess there are two concerns that comes into mind immediately: 1. Would water vapor reduce the lifespan of the solar panel? Water evaporates naturally, especially in a country as hot as India. 2. Would water quality be affected if solar panels are damaged and the shards fall into the water?

I worked in a nuclear research laboratory before. Nuclear power stations are pretty safe as long as it follows the standard operation procedure. For example, the Chernobyl disaster happened when a less experience crew disengaged multiple safety feature for the test. In Fukushima, the Tokyo Electric did not want to spend the money to replace the reactor, so they waited four whole days without responding to the hydrogen build up. Had they followed the established safety procedure from the start, the disaster wouldn't have happened.

As long as the safety procedures are followed, nuclear stations are actually quite a bit safer than hydro or fire stations.

Answering your concerns first :

1. Water vapour will not reduce the lifespan of solar panels, for the cells are kept inside a protective casing, meant to withhold against effects of weather, including rainfall. However, just like any other machinery, they require timely maintenance.
However, creating solar panels right over water channels will significantly reduce the efficiency of the solar panel, with the present generation technology.

If solar radiation coming from Sun to Earth is considered 100%, then about 30% of it is lost due to atmospheric absorption, or simply reflected back by the surface. On an average, 50% relative humidity will form a film over the solar panels, that will result in loss of yet another 15-30% loss of radiation. So, the efficiency of the solar panels may come down to 55-60%.

Then again, the efficiency will also depend on the materials used, prominently two types, cadmium telluride and nanocrystalline silicon.
Here's one article that provides a summary on their efficiency :
The Effect of Water Vapor on the Performance of Solar Cells

2. I will not be bother by the damage of water quality thing. We can have some sensing mechanism and a pre-planned standard operational procedure to deal with that. Again, that's a solvable problem, can be taken care of easily.

I think these kind of projects are aimed at finding a middle-ground, between efficiency and solving the problem of land-acquisition. We can always produce some more solar panels, but land is a limited resource. So, I support the idea.

Thanks, it is good to know. My research concentrate on wind. We do have guys research solar in my office, unfortunately they all run off after the finals.

Ramjet ,

Thanks.

Exactly, but your comment was "Let's move our manufacturing from China to India." Perhaps that comment only meant that in the literal sense, but given the general environment, pretty much anyone will deduce certain things.

Also, just by bringing in the topic of moving manufacturing to India from China, you open up to my counter argument of the futility of that happening.

@nForce ,


This year Japan has financed Norway in the amount of over $1.5 Billion to $3 Billion to produce wind power turbines. They're actually implementing Japanese technology of off-shore win turbines.

This is something that will regenerate energy , renewable power, and a source of power that has little to no carbon footprint. This is something that I believe Japan and India should look into the future. There is a great potential to build these wind turbines in the North of India ; Rajasthan, Gujarat, Arunachal Pradesh, as well as Kashmir are areas that have relatively high amount of wind , and strategically building these wind power plants can theoretically power these states with little to no dependence on natural gas, petro.





In Japan we are now designing and testing giant offshore wind turbines that can be a game changer in regards to efficient renewable power sources.

They look awesome..Must be fun to watch them from upclose.

Few years back, I attended a seminar on improvement of Power plant net heat rate under the provisions of Energy Conservation Act, under the Indo-German Energy Programme conducted at NPTI. What I wrote is what I got from the material I received from the seminar. Here is a snapshot.
