Daintree Rainforest solar to hydrogen microgrid an Australian first

A test-run for Australia’s first solar to hydrogen microgrid is great news for the ecologically sensitive Daintree Rainforest.

A Federal Government grant of $990,150 kicks off the 100 per cent renewable project in Far North Queensland.

On completion, residents in this World Heritage listed area will feed energy from their rooftop solar power systems into a reticulated microgrid. This energy will then be used to create hydrogen. Other than the solar energy, the only other raw material in the production of hydrogen will be water. The only waste product will be oxygen! We can’t have too much of that in most circumstances.

Clean hydrogen microgrid harnesses solar power

Russell O’Doherty is president of Daintree Renewable Energy Inc. He told Newsport that the combined solar energy will help power the green hydrogen production process.

Australia-first solar to hydrogen technology could soon replace diesel generators in the World Heritage Daintree Rainforest.

Solar energy will create hydrogen gas, later used for large-scale electricity generators. If water, rather than gas, is the source material, the only by-product of the process will be hot water.

The second phase of the pilot project will then follow, O’Doherty says. A utility-scale solar farm will be built to complement the solar panel input by members of the community. This will include large-scale battery storage.

Green hydrogen: Powering Australian industry

Zero emissions green hydrogen is the ultimate goal for the fledgling Australian hydrogen industry.

Fossil fuels like gas and coal are the usual source of industrial-scale hydrogen. Natural gas combined with high-temperature steam generates ‘blue’ hydrogen, while coal processing produces ‘brown’ hydrogen. The bulk of the world’s hydrogen comes from natural gas processing.

However, ‘green’ hydrogen uses electrolysis to split water molecules. Renewable energy like wind or solar power can power this clean energy process.

The Federal Government says the Daintree area burns four million litres of diesel fuel every year. If successful, solar to hydrogen microgrids will replace diesel generators in the region and elsewhere.

Off-grid and fringe-grid communities benefit from trial

The trial will include up to 50 off-grid and fringe-of-grid communities. It will measure whether a solar to hydrogen microgrid is cost-effective. As a result, off-grid capabilities can be upgraded with modern technology.

The Morrison Government grant will also investigate new ownership and funding models for local communities.

Federal Leichhardt MP Warren Entsch is excited about the possibilities. He says network costs reduce significantly by moving remote customers to off-grid supply.
