Scientists in South Korea have developed a solar-powered membrane to turn seawater or waste water into drinking water using solar power.
Scientists in South Korea have developed a solar-powered membrane to turn seawater or waste water into drinking water using solar power...

This membrane distillation technology was created by two teams of researchers from the Korea Institute of Science and Technology (KIST) in Seoul - one from the Water Cycle Research Centre led by Dr. Kyung-guen Song, and one from the Centre for Opto-Electronic Materials and Devices, led by Dr. Won-jun Choi. 

In this membrane distillation process, thermal energy is used to evaporate seawater, before it is passed through a hydrophobic membrane that separates the seawater from the water vapour. When the water vapour condenses it forms drinking water.

Because this method of desalination can be undertaken at low temperatures, it is a much more energy-efficient form of thermal desalination.

In this process, the water is heated using solar absorbers. The South Korean teams’ versions of these can absorb up to 85% of solar energy, making them also more efficient than previously designed absorbers.

The greatest need for solar-powered membrane distillation technology is in producing drinking water in underdeveloped parts of the world, or remote and island communities where potable water is hard to source. It is also being suggested that solar technology could be used to provide sources of drinking water at military bases.

Dr. Kyung-guen Song, one of the research leaders from KIST, hinted that the Institute would continue to look for new ways to harness solar power: "This study combines material technologies with water treatment technologies and is significant in that it is a successful case of integrated research that has resulted in revolutionary achievements. We plan to continue developing water treatment technologies that apply advanced materials technologies through ongoing integrated research."

The Awesense Marketplace aims to provide a common framework for companies to collaborate towards the future of clean energy and digital transformation

Awesense has launched what it claims is the only energy-focused repository of solutions built to drive the industry's decarbonization agenda.

The Awesense Marketplace aims to provide a common framework for companies to collaborate towards the future of clean energy and digital transformation, uniting applications, solutions and algorithms to solve energy and grid challenges.

Solutions listed on the marketplace cover a range of cases, and launch companies include Doosan GridTech, Kitu Systems, vadiMAP, LO3 Energy, ENGIN, Utilidata, Clir Renewables, ChargeLab, SensorLink, Exeri, Easy SmartGrid, and Athena Power.

“We are welcoming a new era in the decarbonization of energy systems,” said Mischa Steiner, CEO of Awesense. “The goal of achieving a clean energy future requires collaboration amongst key industry players in the utilities and energy sectors. Sharing resources through the Marketplace means that our customers and partners have a truly seamless approach as we work towards our common goal - ultimately, decarbonizing the world’s energy system.”

Utilities, consulting companies, and other organizations struggle to develop solutions that can be scaled across many jurisdictions due to complex data integration and the lack of a standard, open data model. Using the solutions offered throughout the Marketplace, organizations can rapidly accelerate their transition to a decentralized, decarbonized future and develop solutions that are scalable across industry. The platform will open up new revenue streams in areas such as:

  • Distributed energy resource integration and control

  • Electric vehicle charging

  • Demand response and smart-home management

  • Grid services

  • Intelligent asset management

  • Transactive energy

  • Microgrid management

  • Advanced distribution system management

The new marketplace builds on Awesense's Digital Energy Platform, a digital twin based energy analytics platform that allows utilities to scale at the same pace as the rapidly changing technology landscape of the energy grid.

Together, the Open Energy Data Model and the Awesense Marketplace removes hurdles around data mapping and transformation, expedites data preparation and refining, and provides a common framework for companies to collaborate.

“The energy-specific data model allows utilities, technology companies, consulting firms, and other vendors to build solutions that can be easily integrated by other energy companies, to make a real impact on the industry as a whole, and develop new revenue streams for their organizations” said Steiner. “We’re looking forward to seeing the Awesense Marketplace grow as more partners committed to energy decarbonization join us.”

There are no simple solutions to putting the world on a sustainable path to net-zero emissions, according to the IEA. Reducing global CO2 emissions will require "a broad range of different technologies working across all sectors of the economy in various combinations and applications." it notes

Renewable Energy Hub of South Australia formed

Amp Power Australia has established the Renewable Energy Hub of South Australia, a strategic portfolio of large scale integrated Solar PV, Wind and Battery Energy Storage assets located in South Australia. The hub also includes the siting of the Spencer Gulf Hydrogen Energy Ecoplex, forming part of the South Australian Government's Hydrogen Action Plan. 

The portfolio, acquired from EPS, includes three large Solar PV projects totalling over 1.3 GW of generation, located at Robertstown (636 MW), Bungama (336MW) and Yoorndoo Ilga (388MW) with a total BESS capacity of up to 540MW across the portfolio.

Amp's expansion in Australia will include the implementation of Amp X, a proprietary digital energy platform 100% owned by Amp, which provides a diverse portfolio of disruptive and interoperable grid edge solutions, and includes a smart transformer, which enables real-time autonomous management and optimised dispatch of all forms of distributed generation and loads across the grid. 

Palmetto recently opened its marketplace in Arizona, and is now serving 20 states across the country, claiming its proprietary technology, marketplace business model, and consumer mobile application "are all designed to democratize access to clean energy".
