The world’s largest energy plant

April 19, 2024 By EarthWise Leave a Comment

The largest energy plant in the world is being built in India.  In an area of barren desert in western India near the Pakistani border, Adani Green Energy Limited (or AGEL) is building a sprawling solar and wind power plant that will cover more than 200 square miles.  It will be five times the size of Paris and will produce enough electricity to power 16 million homes.

The Khavda Renewable Energy Park will cost about $20 billion to build and will take about five years to complete.

The success of the plant is critical to India’s efforts to reduce pollution and meet its climate goals.  India is the world’s third-largest energy consuming country.  Even though its energy use and emissions per person are less than half the global average, its enormous population offsets that advantage and its expanding economy and ongoing modernization are driving rapid growth of energy demand.  Energy demand has doubled since 2000 and 80% is still being met by coal, oil, and solid biomass.  India uses massive amounts of coal, and, in fact, the Adani Group of companies is India’s biggest coal importer and a leading miner of the fossil fuel.   Adani represents two sides of the coin.

More than 600 million people in India will be coming into middle and upper income over the next 10 to 15 years and they will have increasing energy needs.  India is in a race to develop clean energy capacity.  If it simply follows the torturous path that China, Europe, and US all have done, the prospects for the global climate are bleak.

Building the world’s largest clean energy plant is just a first small step in the necessary direction.

Energy From Rice Straw | Earth Wise

February 3, 2023 By EarthWise Leave a Comment

Turning rice straw into energy

Rice straw is produced as a byproduct of rice production.  Globally, as much as a billion tons of rice straw is produced each year, three-quarters of it in Asia.  Straw incorporation in soil for fertilization is not practical in most places because with multiple crops per year, there is not enough time for the material to decompose and become good fertilizer.  As a result, open-field straw burning is increasingly the standard practice.

Scientists at Aston University in Birmingham in the UK are embarking on a project to convert rice straw in Indonesia into low-cost energy on a commercial scale.

Indonesia produces 100 million tons of rice waste each year, of which 60% is burned in open fields, causing air pollution. 

The Aston researchers are developing a biomass conversion process based on pyrolysis.  This involves heating the rice straw to high temperatures over 900 degrees Fahrenheit to break it down, producing vapor and solid products.  Both of these things can be used to generate electricity.

A new combustion engine designed by a company called Carnot Limited is capable of converting 70% of the thermal energy extracted from the rice straw into electricity.

Energy extracted in this way could help low and middle-income countries to create their own locally generated energy, thereby reducing emissions, creating jobs, and improving human health.   The biomass electricity is predicted to be cheaper than solar, geothermal, wind, coal, or even subsidized gas-generated power.

The Aston University project will help develop a business model that could support companies and communities to produce local, cheap energy in Indonesia and other countries with biomass capacity.
