Waste Heat: Great Source for Green Hydrogen
As a student, I had worked to develop and pitch the idea to use Organic Rankine Cycle (ORC) for Power Generation to various stakeholders, which was not considered as a viable option due to several constraints at that time. But now reading the results of the Horizon 2020 TASIO project, makes me feel overwhelmed.
As I mentioned in my article “Role of Heat in Decarbonization” (Please see the link in the comment section), recovery, storage, transportation, and utilization of waste heat increases the overall industrial process performance and hence reduces their carbon footprint.
- Waste heat can be utilized from the industrial processes; alternatively, it can be re-used for thermal generation by upgrading the temperature of waste heat to power district heating, hence reducing overall fuel consumption.
- Waste heat can be used to generate carbon-free power.
TAISO project was a pilot project demonstrating direct usage of waste heat for electricity generation through ORC. This project also estimates a potential in Europe of annual 11 TWh of reliable electricity generation through waste heat resulting in Carbon emission saving of 3.1 M Tonnes.
Being reliable and continuous, this electricity can further be used for green hydrogen production. Turboden estimates this will bring the price of hydrogen to €2-3 per Kg.
Let me know your thoughts.
