The Challenge

REPLACING DIESEL WITH A FULLY RENEWABLE ISLAND MICROGRID.

A cluster of islands in Dubai required energy infrastructure built entirely from scratch. Hotel complexes were being constructed with 35 GWh yearly consumption and 24/7 operation — with only 4.5 MW diesel generators as the existing energy source.

Diesel logistics to remote islands are costly, unreliable and ecologically unacceptable. The goal was clear: design a sustainable island microgrid powered entirely by renewable energy — with BESS and hydrogen storage ensuring round-the-clock reliability without any grid connection.

The entire system is operated through an advanced EMS that forecasts production, manages storage dispatch, and optimizes Total Cost of Energy (TCOE).

The goal: design a sustainable island microgrid powered entirely by clean, renewable solar energy.

The Solution

SOLAR + BESS + HYDROGEN — A FULLY RENEWABLE ISLAND SYSTEM.

Volthein designed a multi-layer renewable microgrid combining high-yield solar PV, BESS for daily cycling, hydrogen for multi-day autonomy, and existing diesel generators retained only as last-resort backup — all managed by a single EMS.

01
1,725kWh/kWp
Rooftop + Tracker PV
  • Primary renewable electricity source
  • High yield: up to 1,725 kWh/kWp annually
  • Rooftop + ground tracker installation
  • Feeds direct load and BESS / H₂ charging
02
3.5MW / 14MWh
BESS — Battery Storage
  • Short-term storage for day-to-night shifting
  • Maintains frequency, voltage, power factor
  • Backup reserve during low-solar periods
  • Automated EMS dispatch 24/7
03
1MW / 2,500kg
Hydrogen System
  • Long-term storage in hydrogen tanks
  • Sustains 5 days of full island operation
  • Fuel cell reconverts H₂ into electricity
  • Seasonal buffer for extended low-solar periods
04
4.5MW
Diesel Generators (Existing)
  • Retained only as last-resort backup for redundancy
  • Not used under normal operating conditions
  • Final safety layer — ensures zero downtime under any failure scenario
Project Results

WHAT THE SYSTEM DELIVERS.

0%
Diesel Dependency
Existing 4.5 MW diesel generators replaced as primary source — retained only as last-resort emergency backup.
5days
H₂ Autonomy
Hydrogen storage sustains full island operation for 5 days without any solar generation — unique long-term buffer.
14MWh
Battery Storage
BESS handles day-to-night energy shifting and grid stabilization — maintaining frequency, voltage and power factor 24/7.
3layers
Storage Redundancy
BESS daily cycling + hydrogen seasonal buffer + diesel last-resort — three independent layers ensure zero downtime.
Project Outcome
A fully renewable island microgrid in Dubai — solar PV, BESS and hydrogen storage replacing diesel, with 5-day autonomous operation and zero grid dependency.
