Dubai announces expansive concentrated solar power project
The Dubai Electricity and Water Authority (DEWA) has announced plans to build the world’s largest concentrated solar power (CSP) plant in the Mohammed bin Rashid Al Maktoum Solar Park.
The new project, which aims to generate 1,000MW of clean electricity by 2030, is the second phase of an ongoing solar-installation initiative in Dubai. The 13MW first phase has been operational since October 2013.
Concentrated solar power is generated via moveable rings of solar ‘mirrors’, called heliostats, which direct sunlight to a collection tower where the strength of the sun’s rays then powers a steam turbine to generate electricity.
DEWA’s Managing Director and CEO, Saeed Mohammed Al-Tayer, said that the project is part of the Dubai Clean Energy Strategy 2050 — which has the city striving to derive seven percent of its total power from renewables by 2020, 25 percent by 2030 and 75 percent by 2050.
When completed, the solar park is expected to slash emissions in Dubai by over 6.5 million tonnes of CO2.
Currently, the world’s largest CSP tower is located in Morocco and has a power generation capacity of 150MW.
Dubai’s own CSP plant is expected to be fully operational by April 2017.
Al-Tayer said: “An important advantage of [CSP] is that thermal heat, which is used to produce electricity, can be stored easily, which makes it possible to produce electricity after sunset.
“The plant will have several thousand heliostats located around a tower that receives the radiation reflected by the heliostats which follow the sun’s movement. The heat-transfer fluid is then used to power the steam turbine to generate electricity.”
Drax advances biomass strategy with Pinnacle acquisition
The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.
The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).
This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.
In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.
The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
