Scientists have developed an innovative method to separate lanthanides, crucial for clean energy technologies, by combining substances that attract either lighter or heavier elements. This process promises to reduce the environmental impact and cost of rare earth element extraction, improving efficiency and scalability for industrial applications.
The scientists tested this technique using two different liquids that do not mix — oil and water. In water, they dissolved the water-loving substance; in oil, they added the oil-loving one. They found that the two-substance approach helped separate the lightest and heaviest rare earth elements better than the one-substance method applied previously. They used various methods to study how these organic chemicals and rare earth elements interact.

Traditional Banks Show Skepticism Towards Clean Energy ProjectsTraditional regional banks tend to be skeptical about clean energy projects, which are framed as risky investments that may not yield solid returns. As a result, many banks have little experience with loans for clean energy or efficiency measures. Larger banks with more resources also resist homeowner and small business clean energy projects, focusing their clean energy resources instead on financing large scale solar and wind projects. The opportunity for small borrowers to update with clean energy applications is about to gain momentum.its selections for $20 billion in grant awards under two competitions which create a national clean financing network for clean energy projects and climate solutions across sectors.

Clean Energy Alliance Provides Renewable Energy Options to San Diego CustomersThe Clean Energy Alliance (CEA) is offering renewable and greenhouse gas-free energy options to customers in the San Diego region. Customers will still receive their bills from San Diego Gas & Electric (SDG&E), but CEA will handle the energy procurement. Each city within the alliance has decided that their residents should have 75% clean energy by default.
