This week’s news was full of microgrids. From how technology developed for cryptocurrency is ushering in a shared energy economy to microgrids for marijuana grow operations, we’ve got a news roundup that sounds worthy of the darkest corners of the internet. It’s all above board, though, and part of a growing advanced energy industry!

Virtually every industry is transforming to incorporate data strategically, and the information age has finally arrived in the electric utility industry. With the deployment of smart meters now approaching 50% of all electric meters, utilities are collecting massive amounts of granular data. The question is, how can utilities best utilize all of this data and make it available—and useful—to customers and third parties?

Marine and hydrokinetic power technologies generate electricity from the kinetic energy of moving water, including waves, currents, and tides. Wave energy devices are designed to capture energy from the rising and falling of waves or their forward movement. For example, the relative motion between a buoy at the surface and a fixed tether on the sea floor can be used to drive a generator. Tidal energy can be captured in two ways. First, in places with the right undersea topography, daily currents created by ocean tides can be used to drive underwater turbines. Similar technology can exploit the constant ow of water in rivers or in large-scale ocean currents like the Gulf Stream. Second, in places with large tidal ranges, tidal barrages (dams or barriers) can be built across bays or estuaries to capture energy from the receding tide via turbines as water ows out to sea. Within each category, there are many different technologies in development, particularly for wave energy capture. Proximity to shore, ocean depth, and expected sea conditions are all major considerations for these technologies. Another type of marine energy, called Ocean Thermal Energy Conversion (OTEC), exploits temperature and/or salinity gradients between surface waters and deeper water to drive various power cycles.

On Nov. 17, the Federal Energy Regulatory Commission (FERC) issued a notice of proposed rulemaking (NOPR) that has the potential to significantly expand opportunities for advanced energy technologies in the coming years. The proposed rule will allow more competition from advanced energy technologies in the regional electricity markets under FERC’s jurisdiction, driving down costs for consumers while giving the industry greater chance to grow. AEE has frequently noted that current rules do not allow advanced energy to compete fully in wholesale markets. With unnecessary obstacles removed, the advanced energy industry will be able to grow with the simple force of free markets. With Thanksgiving just behind us, we’re thankful for this effort by FERC to remove market barriers for advanced energy in wholesale markets.

THIS IS ADVANCED ENERGY: Compressed Natural Gas and Liquefied Natural Gas

Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG) are gaining market share as transportation fuels. The technologies for producing, storing and using both CNG and LNG are well developed. With CNG, pipeline natural gas is compressed to 3,000 to 4,000 pounds per square inch (psi) and stored in a pressurized tank on board the vehicle. CNG fueling stations include all the equipment necessary to take natural gas from the local distribution system, compress it, and refuel the vehicles. With LNG, the natural gas must be cooled to about -260°F at which point the methane (the main constituent of natural gas) turns to a liquid. The LNG is stored in insulated cryogenic tanks at the refueling station and on board the vehicle.
