Why the LEDI vision?

Considering the ongoing challenges posed by the global reliance on coal and the influence of fossil fuel interest groups, the grand direction was set in the stone of Longji Energy Corporation’s mission statement. Therefore, the LEDI team structurally focuses on advancing prospective renewable energy processes and technologies.

This commitment is also reflective of the internal challenges of its existing renewable energy development. The home stretch is the hardest, the existing biomass renewable energy development is facing the following hindrances:

The tar removal effectiveness needs further improvement.
The optimal catalytic materials are still being experimented on in a trial-and-error manner and can be costly for the success of any future projects.
The gasification equipment is still built on the existing coal feedstock model, the potential of suitable biomass-oriented equipment and processes is yet to be realized.
The complexity and the time-consuming anaerobic bio-reactions are yet to be addressed by incorporating thermochemical processes to utilize wet biomass more efficiently.
Ultimately, we cannot dwell on the complacency of ‘carbon neutral’, downplaying the call for true green productions, thus, running the risk of overlooking the authentic ‘zero-emission’ goal.

The LEDI vision is to address these challenges. Our research has found the following threads to pursue: Bio-SNG, Hydrothermal Technology, Hydrogen Fuel production and Energy Storage powered by Wind, Solar, Geothermal plants.

Bio-SNG & Hydrothermal Technology

Whether it’s dry or wet biomass feedstock, its composite complexity should not be the hindrance to achieve the ‘carbon neutral’ objective in renewable energy production. Many reports from other bio-energy development projects have stressed that the success of the commercial projects relies on the initial screening/selection of the biomass materials. There are mainly two technological paths to process biomass feedstocks, the thermochemical and the anaerobic reaction.

For dry biomass, thermochemical gasification, methanation and methanol reaction rein more supreme as they can generate bio-sng to produce bio-methane, bio-methanol, and hydrogen for cleaner energy utilities, but the production capacity can be limited by the choice of feedstock, the tar removal effectiveness, the catalytic cost, not to mention the challenges for them to be injected into nationally standardized network. Therefore, LEDI is seeking state of the art technologies and processes to improve the quality of the output bio-sng for the subsequent bio-fuel

For wet biomass, a promising hydrothermal approach has been tested to be effective by many studies, it can benefit Longji Energy’s various energy efficiency improvement plans. The key feature of this technology is its dryer-free energy saving prospect, this can greatly enhance the versatility of the thermochemical process at the existing plants. Not only less energy consumption to process the municipal wastewater sludge, but also the feedstock can be mixed with horticultural residues for better bio-sng output for the energy recycling during the disposal processes. Therefore, LEDI aims at providing cleaner and more energy efficient solutions to help the community dispose the bio-waste.

Hydrogen Fuel Production and Energy Storage Powered by Wind, Solar, and or Geothermal Plants

A promising clean energy source that can push forward the ‘zero-emission’ global agenda to the next level. Not only there is zero carbon emission (water) coming out of the oxidization of this highly energy potent substance, but also it can be used as the power storage buffer for the fluctuating wind, solar, and geothermal power generations.

The renewable energy industry has developed many successful use cases which centered on hydrogen, e.g., the hydrogen fuel cells in transportation and consumer vehicles, however the implementation of a hydrogen infrastructure network relies on the industrial coordination and integration, for the source of this energy is mainly through electrolysis of water, and the energy consumption in its production, if to live up to the ‘green hydrogen’ promise, has to come from other renewable energies, such as wind, solar, biomass, or geothermal.

Therefore, LEDI is actively seeking international and regional cooperation to push hydrogen development to its rightful place in the renewable energy sector.
