Asian Renewable Energy Hub

Last updated

The Asian Renewable Energy Hub (AREH) is a proposal to create one of the world's largest renewable energy plants, in the Pilbara region of Western Australia. It was first proposed in 2014, with plans for the project concept changing several times since then. As of June 2022, the project developers BP, [1] Intercontinental Energy, CWP Global, Vestas, and Pathway Investments were planning to build a mixture of wind power and solar energy power generators which would generate up to 26 gigawatts of power. [2]

Up to 1,743 wind turbines of 290 metres (950 ft) in height would be accommodated in 668,100 hectares (1,651,000 acres) of land, and 18 arrays of solar panels each generating 600 megawatts would cover 1,418 hectares (3,500 acres). [2] It is to be located in the Shire of East Pilbara, about 30 km (19 mi) inland from 80 Mile Beach, with the nearest settlement on the map being Mandora Station. [3] The total size of the scheme would be about 666,030 ha (1,645,800 acres). [4]

The Government of Western Australia gave environmental approval for phase one of the project (15,000MW of power generation, across 6,500 km2 (2,500 sq mi) in October 2020. The project initially aimed to supply power via an undersea power cable (to Indonesia and perhaps on to Singapore [2] ) with a capacity of 15GW, [5] using four cables, each 3,000 km (1,900 mi) long. [2] However, having explored the potential of exporting green hydrogen via the manufacture of ammonia, it was able to aim for an extra 11GW. [5] The plant would use the electricity generated by the wind turbines and solar power to extract hydrogen from water. The hydrogen is then mixed with nitrogen extracted from the air to produce ammonia. [2]

The ammonia is easily transported using tankers, and opens up the possibility for more markets around the world. [2]

For the ten years of project construction, the project is expected to create 5,000 jobs, with about 3,000 ongoing jobs anticipated over its 50-year lifetime. [5] It is planned to create a coastal town campus between Port Hedland and Broome, and a desalination plants will provide most of the water supply needed for both human consumption and plant cooling purposes. [2]

Given the status of "major project" by the federal government in October 2020, [6] the proposed development of the plant enables the goals set under the Western Australian Renewable Hydrogen Strategy to be brought forward from 2040 to 2030. [3]

After a revised proposal was submitted to the Australian Government, in June 2021 Minister for the Environment Sussan Ley ruled this plan unacceptable owing to its potential impact on threatened migratory species and internationally significant wetlands in the area. Eighty Mile Beach is a RAMSAR listed site which provides habitat for several threatened species of migratory birds and a large population of waterbirds, which would be disrupted by the marine components of the project, which would affect tidal movements. The consortium intended to continue to work on the environmental impact plans and mitigation measures, and is confident in developing and delivering a successful project.

In January 2023, Western Australia approved a land allocation for a revised set of seven projects, renamed the Australian Renewable Energy Hub, which total 26 GW of wind and solar capacity that would be used to produce hydrogen and ammonia. BP bought a 40.5% stake in the project in 2022. [7]

Grid energy storage is a collection of methods used for energy storage on a large scale within an electrical power grid. Electrical energy is stored during times when electricity is plentiful and inexpensive or when demand is low, and later returned to the grid when demand is high, and electricity prices tend to be higher.

<span class="mw-page-title-main">Renewable energy in Turkey</span>

Renewables supply a quarter of energy in Turkey, including heat and electricity. Some houses have rooftop solar water heating, and hot water from underground warms many spas and greenhouses. In parts of the west hot rocks are shallow enough to generate electricity as well as heat. Wind turbines, also mainly near western cities and industry, generate a tenth of Turkey’s electricity. Hydropower, mostly from dams in the east, is the only modern renewable energy which is fully exploited. Hydropower averages about a fifth of the country's electricity, but much less in drought years. Apart from wind and hydro, other renewables; such as geothermal, solar and biogas; together generated almost a tenth of Turkey’s electricity in 2022. Furthermore, Türkiye has ranked 5th in Europe and 12th in the world in terms of installed capacity in renewable energy. The share of renewables in Türkiye’s installed power reached to 54% at the end of 2022.

The Port Augusta Renewable Energy Park is a combined wind and solar farm under construction south of Port Augusta in South Australia, Australia. The solar farm is planned to be at the northern end of the site, west of the Augusta Highway and south of Sundrop Farms. The wind turbines will be on both sides of the Augusta Highway, extending south as far as the road to Horrocks Pass. Construction formally started in October 2020 and is estimated to take about 18 months to complete. The total site is about 5,400 hectares.

Green hydrogen (GH2 or GH2) is hydrogen produced by the electrolysis of water, using renewable electricity. Green hydrogen has significantly lower greenhouse gas emissions than grey hydrogen, which is derived from fossil fuels without carbon capture. Green hydrogen may be used to decarbonize sectors that are hard to electrify, such as cement and steel production. Green hydrogen can be used to produce green ammonia, the main constituent of synthetic fertilizer. It can also be used for long-duration grid energy storage, and for long-duration seasonal energy storage.
