A new report released by research firm IHS Markit explains the role gas can play in the transition to net-zero.
The report; Permanent flame – the role of gas in net zero, Says that gas plays a major role in near-term and long-term energy targets due to its ability to convert low-carbon fuels into existing infrastructure, including ammonia, hydrogen, synthetic methane and renewable natural gas.
According to the report, more attention needs to be paid to rebuilding existing infrastructure in order for gas to become a “second pillar” of decarbonation alongside renewable energy.
- Pipelines, transmission and distribution, can send renewable natural gas. First, they can be incorporated into “green” gases to lower their carbon footprint, and they can be re-purchased to send 100% hydrogen in the long run. Also in many gas storage infrastructure.
- Gas-fired power plants may be converted to hydrogen or permanent ammonia, or in some cases carbon retention, use and storage may be delayed.
- Instead of building a liquid hydrogen plant, wastewater can be converted to liquid hydrogen at a lower cost.
- Industrial and domestic gas heaters can be easily converted from natural gas to hydrogen.
“Reconstruction of infrastructure has technical challenges, but the costs are significant, but they are still far less than building new facilities,” said Shankarari Srinivasan, vice president of International and Renewable Gas, ECH Marxit.
And provides flexibility to policy makers and lenders to set up licenses and loans to ensure that any new construction infrastructure is ready for change and to determine performance limits on the life limits it can operate before the property is converted.
Although efforts to increase the use of renewable energy sources such as wind, solar and green hydrogen continue to intensify, the study shows that gas will continue to be an important part of the transition to low carbon dioxide and energy mix.
In general, replacing older and less efficient power plants with natural gas will reduce emissions by 50%. In Asia, the report said, an increase in the use of natural gas in coal-fired power plants could reduce the GHG emissions by about 3% of the total GHG emissions. –Renewable energy world
