Price of Off-Grid Solar Containerized Water Plants with Wind Resistance

Can a green hydrogen production system be integrated with solar photovoltaic?

Green hydrogen production systems will play an important role in the energy transition from fossil-based fuels to zero-carbon technologies. This paper investigates a concept of an off-grid alkaline water electrolyzer plant integrated with solar photovoltaic (PV), wind power, and a battery energy storage system (BESS).

How is energy curtailed in the Off-Grid plant?

The average annual energy curtailed in the off-grid plant is reduced from 18% in the year 2020 to 16% in the year 2035. In year 2040, with the addition of solar PV and a large capacity of BESS to the system, the curtailment is further reduced to 8%.

Can LCoH be minimized in off-grid solar PV–wind systems?

Studies addressing the optimization of the control and component capacities to minimize the LCOH in off-grid solar PV–wind systems with megawatt-scale electrolyzers are limited in number. Off-grid systems can be beneficial in remote or isolated locations where connection to the grid would be difficult or expensive to build.

Should a wind farm be a sole power supply for off-grid alkaline systems?

A sensitivity analysis performed over different installation years and discount rates reveals that for the off-grid alkaline system, the implementation of a wind farm as the sole power supply is the most economical solution until the installation years 2035–2040.
