'Digital Grid Router' Used to Transfer Solar Electricity - News - Solar Power Plant Business
Close but not quite P2P distributed generation, and thankfully without a blockchain. But without a central ISO operator to manage the external controller, this seems a little stunted.

"The android of grid storage" is a good way of describing EOS, a software plug-and-play management system for managing grid energy storage.

ECHONET CONSORTIUM
Looks like the ZigBee Alliance is punting using the 920MHz band for IEEE 802.15.4g compatible PHY/MAC layer services for ECHONETlite, the new japanese standard for electric appliance/equipment energy management and connectivity to HEMS applications.

Getting closer to the ideal home energy management system, this using air sourced heat pumps boosted with solar thermal panels, driving a hot water heater as well as in floor heat transfer loops or traditional radiators, or heat exchangers for forced air HVAC. Now boost this with an HRV, integrated solar PV thermal panels providing heat and electricity, as well as an external fuel cell supplying heat and electricity, a cold thermal storage tank (nighttime ice generation) as a pair to the hot water tank, and a home electrical storage battery, and then you have something awesome.

A ‘Magic Box’ For Your Passivhaus | GreenBuildingAdvisor.com
The Magic Box, AKA heavily integrated thermal compnents for homes such that heat/cold can be used/reused effectively, from HVAC to hot water heaters and boilers for in floor heating. Most of the focus here is heat recovery ventilators, which recover heat energy from hot exhaust air to preheat/heat the evaporator coil of a heat pump. Too bad hardly anyone is selling them.

NAE Website - Coming of Age in New York: The Maturation of Energy Efficiency as a Resource
I like the concept of "market aware energy consumption asset" AKA the smart appliance, that can fiddle with it's operational cycles to time shift energy consumption when energy is cheaper (and possibly chose an energy source, say local vs grid), work in concert with other smart appliances to keep overall consumption below a certain threshold (say to not go over the capacity of a battery bank's output), and possibly cooperate with the local utility or regional ISO.

Consortium for SEP 2 Interoperability
So a couple of major IP transport layer standards organizations are working on compatibility to support smartgrid applications in the home. HomePlug would cover HomePlug aware wired hardware communicating over powerline (PLC) (and covers communicating with electric and hybrid vehicles charging in the garage), while wifi and ZigBee cover mobile and low power sensor hardware. Sure took long enough to do this, and it will be interesting to see the fight between Cisco, the power meter makers, and Android for domination of the home energy management space.

Sharp to Start Evaluating Sharp Eco House, Aiming to Minimize Energy Consumption | Press Releases:SHARP
Interesting demo house, using solar PV, a DC backbone supporting DC appliances, and a home energy storage battery (not clear if they mean a standalone unit using available PHEV/EV type large traction batteries, or literally using a PHEV/EV as the backing battery like in a V2G setup)

Daiwa to Sell Residences With Li-ion Batteries in Japan -- Tech-On!
A step in the right direction, doing distributed grid energy storage. The corporate angle being the cost of storage is offloaded to the consumer directly rather than the power utility. But, they still want to open the damn windows, and japanese people will culturally oblige. How about a thermal energy store below the house instead.

Toyota to Develop Home Energy Management System with Storage Battery -- Tech-On!
Toyota getting in to the home energy management game. Naturally their end goal is the ability to do overnight and quick charging of PHEV and EV type vehicles, but this could be a tidy little business in it's own right if they work with construction suppliers and power companies to link into smart grids. Naturally local generation (solar, wind, natural gas fuelcell) and local storage have big parts to play in a smart grid, so making a good agnostic controller/management system is a must.
