Recently, to improve its upstream layout across the full hydrogen‑energy industrial chain and consolidate stable supply of zero‑carbon green‑hydrogen feedstock, Tianhuan Hydrogen Source has officially signed a strategic cooperation agreement for comprehensive development of a ten‑thousand‑mu giant‑reed park with a state‑owned agriculture‑forestry development platform in Southwest China. A complete integrated industrial‑park planning document covering germplasm R&D, standardized seedling raising, large‑scale planting on marginal land, on‑site harvesting‑storage‑pretreatment, regenerative pyrolysis hydrogen production, deep‑processing of biochar and carbon‑sink‑asset development has been finalized. This marks the scalable and replicable industrial implementation of the company’s “plant‑derived hydrogen” business segment.
In terms of germplasm research, since 2012 the company has built a long‑term industry‑university‑research joint laboratory together with the Chinese Academy of Sciences, Huazhong Agricultural University and West Anhui University. More than a decade of tens of thousands of screening‑and‑iteration trials have yielded five dedicated giant‑reed cultivars adaptable to five extreme land types: heavy saline‑alkali land, alpine mountainous terrain, waterlogged tidal flats, arid barren hills and high‑yield flat farmland. All intellectual property rights for giant‑reed breeding and tissue‑culture technologies are fully owned by the enterprise, eliminating long‑standing industry pain points including unstable supply and price volatility caused by external seedling procurement.
A self‑built GAP‑compliant standardized intelligent tissue‑culture acclimatization workshop houses fully‑automated constant‑temperature‑and‑humidity cultivation production lines, delivering an annual stable output of 80 million seedlings with an outdoor acclimatization survival rate as high as 98 %. It can undertake one‑off full‑seedling delivery for ten‑thousand‑mu‑scale raw‑material bases, while supplying supporting services including complete field‑management technical guidance and planting‑standard manuals for local partners.
Land‑development activities strictly adhere to the principle of avoiding basic farmland. A professional land‑survey team conducts field surveys on plot pH value, soil‑layer structure, hydrological conditions and frost cycles to formulate zoned customized planting schemes. Development targets exclusively consist of idle resources such as abandoned mine wastelands, saline‑alkali tidal flats and low‑yield abandoned land. One‑stop supporting services including land remediation, mechanized planting and year‑round water‑fertilizer‑pest management are provided. Multi‑year guaranteed‑yield agreements can be signed with partners to secure stable raw‑material output. Meanwhile, full‑set application documents are compiled for land‑administration, agriculture‑forestry and ecological‑restoration projects, assisting partners in applying for special policy funds for rural revitalization and ecological governance.
On‑site cost reduction and efficiency improvement are realized in raw‑material harvesting‑storage and pyrolysis production. Self‑developed giant‑reed‑special harvesters and mobile drying units perform crushing and dehydration pretreatment directly in the fields, greatly cutting the weight of fresh feedstock for long‑haul transportation and lowering overall logistics costs by over 30 %. Large enclosed moisture‑proof standardized storage yards in the factory guarantee uninterrupted raw‑material supply for downstream hydrogen‑production lines all year round.
At the core production stage, adopting the proprietary regenerative fast‑pyrolysis patent technology with radiant‑tube indirect heating structure, flue gas and pyrolysis gas are completely physically isolated to prevent impurity contamination of hydrogen. Per ton of dry‑basis giant‑reed can stably produce 1 180 Nm³ high‑purity hydrogen. Three high‑value by‑products — green methanol, green aviation‑kerosene and porous activated biochar — are co‑generated. One single facility enables simultaneous multi‑product output, significantly mitigating operational risks stemming from market‑price fluctuations of individual products.
The by‑product activated biochar features porous adsorption and acid‑base‑neutralizing long‑term soil‑improvement properties. The company also undertakes soil‑remediation projects for saline‑alkali land, heavy‑metal‑contaminated farmland and mine reclamation, delivering full‑process services including biochar spreading, long‑term fertility monitoring and repeated soil‑index testing. A professional carbon‑accounting team quantifies dual carbon‑reduction pathways: carbon sequestration during giant‑reed growth and permanent underground carbon sequestration via biochar. Third‑party‑recognized authoritative carbon‑sink assessment reports are issued to connect with the national carbon‑trading market and generate additional carbon‑asset revenue for the industrial park.
This giant‑reed industrial‑park project represents a rare genuinely carbon‑negative energy‑industry project in China. Unlike traditional fossil‑fuel‑based hydrogen production or straw‑utilization projects that generate carbon emissions, it gains prominent advantages in government evaluation for dual‑carbon demonstration parks and investment‑promotion reviews. Internally, it continuously supplies low‑cost biomass feedstock for the Pengshan hydrogen‑energy equipment manufacturing base. Externally, comprehensive cooperation solutions are available for local governments, energy‑investment enterprises and environmental‑agriculture entities, covering EPC contracting for ten‑thousand‑mu‑scale bases, long‑term guaranteed raw‑material supply, soil remediation and joint carbon‑sink development. It synchronously achieves triple value: industrial development, land restoration and carbon‑emission reduction.
