TECHNICAL AND ECONOMIC STUDY OF THE ENERGY TRANSITION FROM NATURAL GAS TO GREEN HYDROGEN IN THERMAL POWER PLANTS

Summary/Abstract: This research article contributes to the challenge of global warming by presenting the approach of the use of greenhydrogen to reduce greenhouse gases. It shows that CO2 emissions can be significantly reduced in thermal power plantsby replacing natural gas with green hydrogen as a fuel. This work presents the techno-economic study of the energytransition of a 12 MW thermal power plant based on green hydrogen. The presented study is based on the energyconsumption of Nigeria, 73% of which is covered by natural gas thermal power plants. The obtained results show thatthe cost of this transition is ca. 17 million dollars (USD) for a reduction of 114 𝑡𝐶𝑂2 per plant with a return on investmentbetween 4-5 years. In addition, through modeling and numerical simulation, this article shows that estimated return oninvestment can be shortened by using the thermal power resulting from the turbine, through industrial use.
