It involves the capture of CO2 emitted during industrial processes, the transport of the gaseous compound via ship or pipeline, and either its use as a resource to create valuable products or services or its permanent storage deep underground in geological formations.

它包括捕获工业过程中排放的二氧化碳，通过船舶或管道运输气态化合物，以及将其用作创造有价值产品或服务的资源，或将其永久储存在地质构造的地下深处。

Hydrogen's liquefied form has also garnered wide attention due to advantages in lower costs and higher efficiency, compared with its gaseous form, when it comes to storage, large-scale use and long-distance transportation, Zhu said.

"Without the need to build pipes, it is relatively cheaper and safer to move hydrogen in a liquid than in a gaseous state, even though nearly all transmission methods remain expensive at present," said Lin Boqiang, dean of the China Institute for Studies in Energy Policy at Xiamen University.

The main storage and transportation mode of hydrogen energy in China is high-pressure gaseous hydrogen storage, which is suitable for small-scale and short-distance transportation.

China's biomass energy resources mainly include straw and other agricultural wastes, such as waste from forestry and forest product processing, animal manure, energy crops and plantations, organic effluents from industry and household waste, which can be burned directly for heat or converted to renewable gaseous and liquid fuels through chemical, thermal and biochemical processes.

Biomass can be burned directly for heat, or converted to renewable gaseous and liquid fuels through thermal, chemical and biochemical processes.

It also demonstrated that most of the liquefied natural gas came from Australia, ASEAN countries and Qatar, while natural gas in the gaseous state mainly came from Turkmenistan and Kazakhstan.

It can be burned to generate heat or electricity, or it can be converted into gaseous or liquid fuels.

It is the world's first heavy duty truck that can run for over 1,000 km on gaseous hydrogen, said the Guangdong province-based company.

The company said that compared with underwater torches overseas that use solid fuel and whose flames cause pollution, those for Beijing 2022 use gaseous fuel that is smokeless and causes no pollution.

Hydrogen can be transported in a gaseous state via pipelines and as a liquid by ships, much like liquefied natural gas (LNG).
