Power-to-X! Kubuqi 400MW Wind/Solar Power to H2 Integration Project Placed on Line for Publicity

2023-10-10

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/LNGsustainable 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.

 

On Sep 21th, Kubuqi, Ordos 400MW wind/solar power to H2 integration demo project (wind power/PV/energy storage/H2 generation/H2 storage/grid & piping) social stability risk assessment data were placed on line for publicity.

 

Construction site of the project would locate in Duquetara Town, Hangjin County, Ordos City. The project is planned to build a 250MW wind power farm, a 150MW PV power station, to supply green power to a 41,000Nm3/h hydrogen unit. In this way, the project is to produce 15.46kt/a of green H2, as the substitute to part of coal-based H2 generated in Duquetara Industry Park, As accessories, a 205,000Nm3 H2 storage facility (for 5h H2 storage), a 220kV booster station, and a 220kV H2 unit substation would be included in the construction package,

 

H2 generation/H2 storage subproject: (1) to build a water electrolysis to 15.46kt/a H2 system, based on CNY740mn investment, including a 220kV substation for the H2 generation unit. (2) to build a 240,000Nm3 H2 storage facility, based on CNY130mn investment, the volume capacity is the equivalence of 205MW chemical energy storage/5h, composed of spherical H2 storage tanks and compressor. Total investment on the project is estimated of CNY870mn, CNY174mn are to be sourced from self-owned pool and the rest CNY696mn as bank loan. The project is scheduled to reach completion in a 15-month period.

 

The project is appointed to Inner Mongolia Kubuqi Green Power Hydrogen Technology Co Ltd, a JV between Elion Clean Energy and SPIC Group Inner Mongolia Energy Co Ltd, to implement.


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.
