India could lead clean coal charge

India is the place to be.

It looks to be poised to lead the ‘clean coal’ charge.

Now, before we get to the crux of the article below, let’s remember there is no such thing as ‘clean’ coal. But there is ‘cleaner’ coal.

What makes coal ‘dirty’ is particulate matter, sulphur dioxide (SOx) and nitrous oxide (NOx) emissions. These impact air quality and human health.

Modern high efficiency, low emissions (HELE) power stations, of which there are more than 725 operating across East Asia right now with a further 1,100 under construction or in the pipeline, deal very well with the above issues through increased efficiency and ‘scrubbing’.

On the other hand, CO2 is an odourless, colourless gas. It causes no particulate emissions nor any direct harm to plant or animal life. It is plant food and the foundation for carbon-based life on earth. However, there is the concern that it is having a catastrophic warming effect as its concentration in the atmosphere increases.

Unlike the well established, affordable methods for capturing particulates or sulphur, capturing and storing CO2 is difficult and expensive.

HELE plants reduce CO2 emissions by being more efficient, emitting less CO2 per megawatt hour than older style plants.

This means, if ‘capture and storage’ technology is added to a HELE plant, there’s less CO2 to deal with and proportionally lower cost to implement and operate.

This is all well and good for black coal. HELE power stations are designed to use black coal with its low moisture and high energy content.

Off the shelf, HELE plants aren’t suitable for use with brown coal because of its high moisture and low energy content. They need a pre-drying process.

Drying is easy. Drying efficiently and cost-effectively has proved highly elusive. The ‘holy grail’ of brown coal R&D for decades has been to find a cost-effective drying solution. The approach always involved energy-intensive methods that employed high temperature, high pressure, or both. Most created a wastewater clean-up issue too. The energy and cost proved to be a zero or negative sum game. The energy input required to ‘heat and squeeze’ the coal was more than the uplift in the energy value of the finished product.

Our Coldry process is different.

Coldry is a low temperature, low-pressure solution with the potential to cost-effectively deliver a ‘black coal equivalent’ product suitable for use in HELE power stations.

In this respect, our Coldry-HELE technology could deliver a CO2 reduction of between 42% and 63% compared to traditional brown coal power generators.

Now that we have that context, take a look at the below article which highlights:

  • India will account for nearly 30% of the entire global increase in energy demand through 2040.
  • India’s share of worldwide energy use in 2040 (11%) will still not have caught up with its projected 18% share of the overall global population.
  • The IEA also projects strong growth in energy demand in Southeast Asia over the same period, with the size of the regional economy tripling over the next 22 years.
  • Despite this growth, ASEAN nations will continue to struggle to overcome energy poverty. A total of 240 million people in India and 65 million people in Southeast Asia currently do not have access to electricity.
  • Renewables-focused schemes like India’s use of solar panels to electrify remote villages have failed to solve the problem.
  • Indonesia also aims to add 35 gigawatts of energy capacity by 2020, with 70% of the increase to come from coal-fired energy.
  • Taking the whole of ASEAN into consideration, soaring consumption means demand for coal is projected to account for some 34% of total primary energy demand by 2040.
  • To meet that demand, ASEAN’s imports of fossil fuels will grow across the board. Despite substantial coal production in Indonesia, the region will actually become a net importer of coal.

For countries like India, the increased use of coal to deliver universal access to electricity, while meeting their pledge to reduce emissions intensity by 35% from 2005 levels by 2030 means a focus on clean coal technologies is essential.

Most clean coal technologies focus on black coal.

Our Coldry technology focuses on enabling the application of black coal solutions to brown coal assets.

India could wind up leading ASEAN’s clean coal charge

Asia Times | 16 Jan 2018 | Jon Connars

Anniversaries are always a time for both reflection and preparation, and India’s 69th Republic Day will be no different. On January 26, all 10 ASEAN members will attend a major summit in New Delhi to celebrate seven decades of Indian constitutional democracy. All sides will, of course, celebrate that past with one eye firmly set on their own present and future interests.
