NGI 10,000A Power Supplies Drive Energy Transition & Technology Innovation

Against the backdrop of the global energy transition toward renewable energy, the power grid faces multiple challenges, including transmission losses and the stability of new energy grid integration. Cutting-edge technologies such as green hydrogen production, superconducting power transmission, and controlled nuclear fusion are becoming key enablers for building a new energy system due to their potential to enhance system flexibility and reduce carbon emissions. Mega-ampere-level power supplies are the "energy cornerstone" driving breakthroughs in these technologies, and their technical capabilities are directly related to the development of strategic emerging industries and scientific research.

Green Hydrogen Production: Efficiency is Key

As the "cleanest energy source," the efficiency of green hydrogen production has a critical impact on its economic viability and commercialization process. The core of this lies in the technological optimization of the water electrolysis process, which encompasses material innovation, structural optimization, and system management.

The hydrogen production process through water electrolysis requires a high current DC power supply (typically in the range of thousands to tens of thousands of amperes) to drive the electrolysis cell reaction. For high current power supplies, three key technological requirements need to be addressed:

Low-Voltage High Current Output

To explore hydrogen production efficiency, the electrolysis cell must be powered by low-voltage high-current output to drive the water electrolysis reaction.

High Precision

The calculation of conversion efficiency is closely related to errors in voltage and current. High-precision output is crucial to ensure the accuracy of the test parameters.

Long-Term Stability

Electrolysis cells typically need to run continuously for extended periods. Since the purity of the electrolysis product is linked to current stability, the power supply must be capable of long-term stable and reliable operation.

Superconducting Power: The "Dark Horse" of Energy

Superconducting technology, with its near-zero loss physical properties, is seen as a key solution to address the future power grid's capacity bottleneck, improve energy utilization efficiency, and integrate large-scale renewable energy. The main applications of superconducting technology in energy transition include the following four scenarios:

Superconducting Cables

Known as the "power highways," these are ideal solutions for expanding urban power grids and reducing transmission losses.

Superconducting Fault Current Limiters

Acting as the "smart guardians" of the grid, these devices use the "quenching" properties of superconducting materials (transitioning from zero resistance to high resistance) to control fault currents within safe limits when a short circuit occurs.

Superconducting Magnetic Energy Storage (SMES)

This system stores electrical energy in the form of a magnetic field using superconducting coils, akin to a "super mobile power supply" for the grid. It offers high charge and discharge efficiency and nearly infinite cycle life.

Superconducting Tokamak Coils

Controlled nuclear fusion is often referred to as the "ultimate energy." Superconducting materials are used to create magnetic confinement devices (tokamak coils) that generate strong magnetic fields to confine high-temperature plasma, creating the necessary high-temperature and high-pressure environment to facilitate nuclear fusion reactions.

Superconducting materials have three critical characteristics: critical temperature, critical current, and critical magnetic field. When researching new superconducting materials and exploring application scenarios, it is necessary to assess their performance under both practical and critical conditions. This requires power supplies capable of ultra-high current stable output, extremely high stability and precision, and rapid dynamic response.

Demanding both high current and high performance presents an extreme challenge to the precision, stability, and thermal management of 10,000-ampere-level high-current power supplies. Behind this lies breakthrough innovation in three core technologies:
