New method can make cheaper solar energy storage

Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes water-splitting technologies too expensive to commercialize. EPFL scientists have now developed a simple, unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost. The work is published in Nature Communications. Many different materials have been considered for use in direct solar-to-hydrogen conversion technologies but "2-D materials" have recently been identified as promising candidates. In general these materials—which famously include graphene—have extraordinary electronic properties. However, harvesting usable amounts of solar energy requires large areas of solar panels, and it is notoriously difficult and expensive to fabricate thin films of 2-D materials at such a scale and maintain good performance. Kevin Sivula and colleagues at EPFL addressed this problem with an innovative and cheap method that uses the boundary between two non-mixing liquids. The researchers focused on one of the best 2-D materials for solar water splitting, called "tungsten diselenide". Past studies have shown that this material has a great efficiency for converting solar energy directly into hydrogen fuel while also being highly stable.   Cont'd...

Ballard Announces Acquisition of Protonex

Ballard Power Systems (NASDAQ: BLDP; TSX: BLD) today announced that it has signed a definitive agreement to acquire Protonex Technology Corporation ("Protonex"; www.protonex.com), a leading designer and manufacturer of advanced power management products and portable fuel cell solutions. As consideration for the transaction, valued at $30 million, Ballard is assuming and paying Protonex's debt obligations at closing, currently estimated at approximately $4.4 million, and paying the balance of approximately $25.6 million through the issuance of 11.2 million Ballard shares. The number of Ballard shares to be issued is subject to adjustment based on the final debt obligations at closing.

Vanadium Flow Batteries for Global Academy of Technology (GAT) College

By implementing the IMERGY storage solution in the premises, GAT is able to store the energy produced by the PV panels during the day and use it during the non-solar time, thus eliminating the diesel generator run to provide clean power when needed.

Is Adding Solar Batteries Worth it?

Seeking to help states better address the value proposition of solar+storage systems, the Interstate Renewable Energy Council, Inc. (IREC) engaged Clean Power Research (CPR) to develop a methodology that could be used to value solar energy coupled with battery storage. The methodology described in the report can be applied in any location. It focuses on Hawaii as an example, as it is likely to be an early adopter of storage regulations.  "The concept of adding batteries alongside a utility customer's solar array intrigues utility customers, solar developers, and utility planners on several levels, but the underlying question for everyone is whether adding batteries is 'worth it,'" says Jason Keyes, Partner at Keyes, Fox & Wiedman LLP, attorney for IREC and report collaborator.  Though still at a nascent stage, the recent rapid growth in the distributed energy storage market suggests that now is an opportune time to take a closer look at distributed energy storage, especially in combination with distributed solar, and the values it has to offer. The new IREC study lays out the methodology to do just that and sets forth a pathway for more robust analysis and dialogue.   Cont'd...

24M Introduces the Semisolid Lithium-Ion Battery

Today, 24M emerged from stealth mode to introduce the semisolid lithium-ion cell, a revolutionary technology that solves the grand challenge of energy storage by enabling a new, cost-effective class of the lithium-ion battery. 24M’s semisolid lithium-ion is the most significant advancement in lithium-ion technology in more than two decades and combines an overhaul in battery cell design with a series of manufacturing innovations that, when fully implemented, will slash today’s lithium-ion costs by 50% and improve the performance of lithium-ion batteries. The technology will accelerate the global adoption of affordable energy storage. Until now, the energy storage field has had two options to try to drive down costs – build massive and complex factories to produce lithium-ion batteries in high volumes or pursue entirely new chemistries that may never move from the lab to the commercial floor. With the invention of the semisolid lithium-ion battery, 24M presents a third option – work with the world’s preferred energy storage chemistry and unlock new opportunities for cost reductions through new cell design and manufacturing innovations. 24M’s platform is the most significant advancement in lithium-ion technology since its debut more than 20 years ago.
