Experts describe coal gasification-liquefaction harmful to environment

KARACHI: Experts on Thursday warned against the harmful economic and environmental impacts of the government’s move to produce energy by changing coal to gas (CTG) and coal to liquid (CTL). They said it would also increase Pakistan’s reliance on fossil-fuels.

 

Speaking at a webinar organized by the Alliance for Climate Justice and Clean Energy (ACJCE), they advised the government to look at the experience of other countries which have used CTG) and CTL technologies and include the lessons learnt from there in its policies. They argued that the government’s policies and plans aimed at making a transition to green energy should be informed by Pakistan’s economic and financial realities. These policies and plans should also consider the declining prices of climate-friendly technologies like solar, wind and green hydrogen, they said.

 

The speakers shared the findings of their studies on economic and environmental viability of Pakistan’s intention to use domestic coal for the production of gas, diesel and fertilizers. The intention was announced by Prime Minister Imran Khan while addressing the Climate Ambition Summit in December 2020.

 

Simon Nicholas, an energy finance analyst with Institute for Energy Economics and Financial Analysis (IEEFA), said it was the unaffordable nature of surplus coal-fired power that led the government of Pakistan to seek debt relief from China. The CTG and CTL proposals came as the coal-fired power was already contributing to ballooning capacity payments, accelerating the build-up of circular debt, he said.

 

Referring to various similar experiences in the United States, South Africa and Indonesia, he argued that the projects to convert coal into gas and liquid had been heavily reliant on the government subsidies everywhere in the world.

 

“Now is not the time for Pakistan to be increasing fossil fuel dependence along with the subsidies needed to support their consumption,” he said. Given the much higher than anticipated water usage by Kemper project, he said, the water intensive technologies to be used for CTG and CTL processes would be inappropriate in a water stressed region like Thar.

 

Haneea Isaad, an energy research associate at the Rural Development Policy Institute (RDPI), said Pakistan’s need to diversify its energy mix and reduce its dependence on imported fuel was understandable. She stated that the move to coal gasification and coal liquefaction could have serious economic and financial implications for Pakistan without a significant reduction in the cost of extracting coal from Thar.

 

She argued that providing the gas produced from coal to fertilizer industry would only increase the prices of fertilizers enormously since this industry is currently using subsidized natural gas produced domestically. On the other hand, she said, if CTL and CTG fuels are used for power generation, the cost of electricity could go up almost by Rs 10/KWh for diesel-based generation and by Rsa 2/KWh for gas-fired power production. Isaad said that Pakistan’s increased dependence on coal-based power generation would significantly increase its emissions of greenhouse gases.
