If We Can Bury Carbon Dioxide, Why Not Use It to Make Electricity? (MIT Technology Review)

A startup is trying to demonstrate that carbon dioxide can be used to make clean geothermal power economical and far more widespread.

Researchers might have found a way to economically capture carbon dioxide from power plants and permanently store it underground. The idea is to turn carbon dioxide storage sites into geothermal power plants.

If it works, the technology would provide both the electricity needed to pump carbon dioxide underground and a source of revenue to offset the high cost of capturing carbon dioxide at power plants, compressing it, and shipping it to storage sites.

That technology, known as carbon capture and storage, or CCS, will be essential for reducing greenhouse gas emissions. But because large-scale CCS would be prohibitively expensive, development of the technology has been too slow to meet climate change targets, according to the International Energy Agency.
