- Product and R&D
NEXON STAR's energy self-sufficiency system is a patented system that can self-produce the power consumption of green hydrogen production water electrolysis facilities and use it as renewable energy. In the case of Korea, the daily average power generation time of solar power is 3 hours, and operation efficiency is low, so a large site is required.
NEXON STAR's “Energy self-sufficient water electrolysis system” and “energy self-sufficient photovoltaic power generation system” patented technologies can operate 24 hours a day by self-producing power consumption, thereby increasing operational efficiency. It can be maximized and construction using a small site is possible, so hydrogen production and charging (hydrogen, electricity) can be operated in one place. It can be built and applied to RE100 realization, self-supporting villages and self-supporting buildings.
According to the IEA, the green hydrogen cost structure accounts for 65% of electricity cost, 32% of CAPEX, and 5% of OPEX, so electricity cost reduction is a key factor in lowering the unit price of green hydrogen, and operational efficiency is 50% In the event of an abnormal increase, the unit price of hydrogen is reduced by 60%, and 24-hour operation also greatly contributes to cost reduction.
When hydrogen is produced by applying two patents for energy-free water electrolysis system applied by NEXON STAR, 24-hour operation is possible and it accounts for 50-75% of the production cost of green hydrogen. It is possible to drastically reduce the power consumption of hydrogen, which can drastically reduce the cost of hydrogen production.
NEXON STAR ultimately aims for a green hydrogen unit price of $1, and it is a self-reliant renewable energy that can cover about 4.5 to 6 kWh of power consumption to produce 1Nm3 of green hydrogen. We plan to actively advance into overseas markets where green hydrogen production is difficult due to the intermittency and locality of renewable energy overseas as well as in Korea with the patent for “Energy Independent Water Electrolysis System”.

In September 2022, Lee & Mok for the purpose of evaluating the technicality of NEXON STAR's patented technologies, "Energy Self-Sufficient Water Electrolysis System" and "Energy Self-Sufficient Solar Power Generation System" We commissioned a patent law firm to conduct a technical evaluation.
In detail, it is to determine whether systems implemented with patented technology can actually produce power and achieve power cost reduction. As a result of the evaluation, both of the target patents It turns out that they have the technology to actually generate power and achieve power cost savings.
In addition, as a result of the prior art search, no prior art was found, so it was evaluated that both patent technologies could be strong patents. Evaluation Patent Attorney Cheol-Woong Park is a patent attorney with over 20 years of experience as a patent attorney, Department of Chemical Engineering, Seoul National University, Ph.D.

NEXON STAR's patented technology, "Energy Self-Sufficient Solar Power Generation System" and the methodology of applying carbon credits to "Energy Self-Sufficient Complex Charging Station" using patented technology December 2022 for the purpose of calculating application conditions, greenhouse gas emission reduction, sales revenue, etc. for each business scenario for obtaining carbon credits We commissioned ATR, an environmental consulting company, to conduct a carbon credit diagnosis.
For the energy self-sufficient solar power generation system, UNFCCC's CDM methodology is reviewed for application of mandatory reduction projects, and energy self-sufficient complex charging stations are registered in the voluntary market (VERRA). The methodology was reviewed, and as a result of the review, the expected revenue of carbon credits for 10 years of the energy-independent solar power generation system is about KRW 1.2 billion. In addition, in the case of the solar power generation system It has been diagnosed that it is possible to secure additional revenue of approximately KRW 5.6 billion when selling the generated power by connecting it to the power system.
In the case of energy self-sufficient complex charging stations, the reduction amount was about twice as high as that of the photovoltaic power generation system, and the carbon credits of the voluntary market (VERRA) With the price (KRW 10,000/tCO2) applied, the total revenue for 10 years was diagnosed as approximately KRW 860 million.
