In the morning of Sep 25th, Shenghong PC 100kt/a CO2-to-green methanol plant, built in Xuwei New District, Lianyungang City, was officially announced to start up.
The project applies Iceland Carbon Recycle International developed ETL process, would actively absorb 150kt/a carbon dioxide to form a 100kt/a green low carbon methanol process demo unit.
Comparing to absorption of carbon dioxide and other greenhouse gases by the traditional way of forestation, the ”simulated photosynthesis” of the plant has stronger capability to absorb CO2, with up to 100% recovery conversion in addition to indirect reduction of 550kt/a CO2 emission, an equivalence of 37,000 hectares (370sqkm) forestation.
Power to X process is to transform electricity into other forms of products easier to storage so as to satisfy the demand on energy, chemicals and materials of individual industry sectors. As of the date, most representative Power to X route is the green hydrogen framework, i.e. to use renewable energy based electricity (Power) for green hydrogen generation through water electrolysis, and further to convert into multiple forms of green fuels and/or energy storage media (X). In addition, the technology of making syngas from CO2 and water through electrocatalytic reduction, and then producing high-value products such as methanol, ethylene and ethanol, has also been successfully developed, and is expected to be another important pathway for Power to X.
Mainstream water electrolysis processes include alkaline water electrolysis (AWE) and proton exchange membrane (PEM) water electrolysis. AWE is a relatively matured process featuring of bigger single unit capacity and lower cost, hence occupying the majority market share; on the other hand, PEM applies higher current density and thus better responds to the green power rate fluctuation, and therefore is believed of great developing potential. At the same time, SOEC and AEM processes are being promoted for bulk production and commercial application 。
Power to X can not only produce energy, but also materials and chemicals. The water electrolysis-based green hydrogen itself is an important direction of energy development. Use of green hydrogen and CO2 can synthesize green methanol, green syngas (H2/CO) and green ethanol etc; Using green methanol or green syngas as raw material, the industry can produce sustainable aviation fuel (SAF), gasoline, diesel, olefins and aromatics etc; green hydrogen can also be used for green ammonia production, as fertilizer raw material, or direct as an energy source.
According to an ASIACHEM research, Chinese wind power, PV power and energy storage industries are going on the way of cost-down while water electrolysis to H2 process is further improved to reduce cost and increase energy efficiency. ASIACHEM “China Green Ammonia Industry Annual Report” showed the data that when green power cost gets down to CNY0.1/kWh, corresponding Power to X route green methanol and green ammonia costs would be CNY2758/t and 2683/t respectively, forming a preliminary cost competition ability.
2023 Power to X Techno-Economic Seminar is to be held on Nov 29th in Suzhou. The conference would discuss the global Power to X process & project development trend, China green power /hydrogen process, equipment & cost foreground, Power to X route produced green methanol, green ammonia, green ethanol, green syngas, SNG/LNG、sustainable aviation fuel (SAF), gasoline, diesel, olefins/aromatics, CO2 electrocatalytic reduction to syngas and high value products technology, automation, electric and digital technology & equipment serving Power to X process etc.
