In a major stride towards cleaner energy, Electricity Generating Plc (Egco), a subsidiary of Thailand’s state-run Electricity Generating Authority, has unveiled a hydrogen program aimed at reducing carbon dioxide emissions.
The program is being implemented at the Linden Cogen thermal cogeneration plant’s Unit 6, located in the United States. By blending hydrogen-rich off-gas from the nearby Phillips 66 Bayway Refinery with natural gas, the program seeks to generate electricity while minimizing the reliance on carbon-intensive fuels. This article will delve into the goals, technology, potential impact, and challenges associated with Egco’s hydrogen program, supported by concrete evidence and reliable sources.
The primary goal of Egco’s hydrogen program is to significantly reduce carbon dioxide emissions by decreasing the volume of natural gas required for electricity generation and steam production. By utilizing hydrogen-rich off-gas from the nearby oil refinery, the program aims to enhance the operational efficiency of both the refinery and the Linden Cogen Unit 6 power plant. The ultimate objective is to promote the adoption of cleaner fuels and cutting-edge power generation technologies in line with sustainability and regulatory guidelines.
Egco’s hydrogen program involves the combustion of a blend of natural gas and off-gas, which contains hydrogen, to produce electricity. Off-gas, a byproduct of crude oil refining, is sourced from the Phillips 66 Bayway Refinery and combined with natural gas to power the gas turbine of the Linden Cogen Unit 6. This innovative approach enables the power plant to generate electricity while reducing carbon dioxide emissions.
The hydrogen program at Linden Cogen Unit 6 is expected to have a significant impact on reducing carbon dioxide emissions. According to Thepparat Theppitak, Egco’s President, the program could lead to a nearly 10% reduction in annual carbon dioxide emissions from the power plant. By utilizing hydrogen-rich off-gas, the volume of natural gas required for electricity generation and steam production can be reduced, resulting in a more sustainable and environmentally friendly operation.
While the hydrogen program holds immense potential, several challenges must be addressed for its successful implementation. Ensuring a reliable supply of hydrogen-rich off-gas from the nearby refinery is crucial. Additionally, the blending process and combustion of hydrogen and natural gas need to be carefully managed to maintain operational efficiency and emissions control. Collaboration between Egco, the refinery, and other stakeholders is essential for the long-term success of the program.
The Linden Cogen complex, comprising Units 1 to 6, is a thermal cogeneration plant with a total capacity of 972MW. Egco holds a 28% stake in the complex, alongside other partners. The introduction of the hydrogen program represents a significant milestone in Egco’s journey towards greener and more sustainable energy production.
