1. Low energy consumption
The voltage of the conventional electrolyzer is 2V, and the
current density is 3000A/㎡, while the new electrolyzer
HELA2000/HELA2000Plus can reach the current density of 4300A/㎡
under the voltage of 1.92V in the small chamber. Therefore,
electricity consumption is reduced compared to conventional
electrolyzers. The DC power consumption of the 2000Nm³/h Hygreen
electrolyzer is less than 4.6kW h/Nm³H2, and the minimum of Plus
is 4.2-4.4kW·h/Nm³H2, which is 2.13% lower than the DC power
consumption of the conventional electrolyzer (4.7kW·h/Nm³H2), and
the highest reduction is 6.38% or more.
2. Wide load
The new type of electrolyzer adopted has a maximum adjustable
range of 110%. The new Hygreen electrolyzer has a current density
of 4300A/㎡ under the voltage of 1.92V in the small chamber, and a
current density of 6000 A/㎡ under the voltage of 2V in the small
chamber. It is more adaptable to the high volatility of renewable
energy and provides a more economical solution and possibility
for a more reasonable allocation of hydrogen generation from
photovoltaic wind power.
3. Boot speed
Improved the control method and shortened the start-up
time.
The volume of the electrolytic cell is greatly reduced by
increasing the current density, which is beneficial to the
temperature rise and temperature control of the electrolytic
cell. Greatly reduces electrolyzer full load state. PART 04

4. Small size and highly economical
The change of materials also greatly reduces the weight of the
electrolyzer, which is reduced to about 70% of the weight of the
original electrolyzer. Greatly reduces engineering problems
during assembly, transportation, installation, commissioning,
operation and maintenance. The cost of transportation,
installation, commissioning, operation and after-sales
maintenance is reduced. Low power consumption and wide load
greatly reduce the operating costs of the project, improve the
matching degree of power generation and hydrogen generation, and
thus increase the return on investment of the overall green
hydrogen project.
5. High performance
The new electrolyzer structure has greatly improved the purity
problem in the traditional diaphragm, and improved the purity of
the hydrogen/oxygen. The purity of oxygen before purification is
increased to over 98.5%. The purity of the hydrogen produced by
the electrolyzer is above 99.8.
6. Life Span,Stability and Safety
The electrolytic cell adopts a flat plate, which avoids the
disadvantage of the diaphragm being damaged as the usage time
increase in the conventional electrolytic cell, which was caused
by the difference in the plate stamping nipple, thus ensuring the
life span, stability and safety of the electrolytic cell.
