Jocelyn Timperley for BusinessGreen: A new energy storage technology currently under development by Siemens is set to see excess wind energy converted to heat rocks, allowing the energy to be stored using an insulated cover.
The system consists of a fan that uses an electrically-heated air flow to heat the stones to high temperatures, with the thermal energy then converted back to electricity when needed using a steam turbine.
The simple principle of the set-up promises to deliver a low-cost way of storing energy, Siemens said, with the only limit to the concept being the space required for the rock-filled insulated container. Cont'd...

Derek Markham for TreeHugger: This startup is reinventing the solar panel, and aims to cut the cost of integrating clean power and energy storage to homes by half.
Home solar has the potential to reduce, and even eliminate, electricity costs for many people, but even with the rapid advancements we're seeing in solar technology, there are still weak points that can be addressed and overcome, such as energy storage and 'smart' home integration. But a newcomer to the residential solar scene believes it has the answer, in the form of a standalone solar and battery unit which can be used singly or connected in an array, and which may be able to lower the overall costs considerably.
SunCulture's SolPad solar device integrates solid state batteries directly into the solar panels themselves, offering its users the ability to not only generate their own clean electricity, but to also store if for use after dark or during peak demand times, when electricity costs are higher. The SolPad units also incorporate an inverter, which converts the electricity from the DC generated and stored by the device to the AC required by most household appliances, and includes "intelligent software" that communicates with both the users and with their home's systems, allowing for granular control over which rooms or devices will receive the solar power.
