The Bureau of Land Management today announced that construction of the Crimson Energy Storage Project, a 350-megawatt battery storage system in eastern Riverside County, is now complete, and the system is in operation and expanding grid capacity. The battery storage project will provide 1400 megawatt-hours of electricity at full capacity and is a significant milestone in the Biden-Harris administration’s efforts to modernize America’s power infrastructure in the West and achieve a goal of 100 percent carbon-free electricity by 2035.

Sandia National Laboratories electrical engineers Rachid Darbali-Zamora, front, and Lee Raskin test out an algorithm on a hardware-in-the-loop set-up at the Distributed Energy Technologies Laboratory. Rachid and Lee are part of a team working with NASA to design a reliable and resilient microgrid to power a future base camp on the moon.

Robyn Williams: There's a massive revolution underway. Steve Chu, Nobel prize-winner and US Energy Secretary, noted this a couple of weeks ago, he said, 'The price of photovoltaics dropped 80% in one year, and by 40% in another year.' Has the world changed and we haven't noticed?

Oregon Alta Rock EGS Geothermal
If you care about clean energy, the BLM is a major leader in making solar, wind, and geothermal energy possible.
Since 2009, BLM has approved 57 renewable energy projects (34 solar, 11 wind, and 12 geothermal) with potential for over 15,000 MWs, or enough to power more than 5 million homes and create some 26,000 jobs. There are currently over 17,000 MWs of renewable energy projects permitted on public land, including 2,379 MWs of renewable energy projects approved prior to 2009.
BLM is focused on approving renewable energy development on public lands in accelerated, but environmentally-responsible manner; ensuring protection of signature landscapes, wildlife habitats, and cultural resources.
For the years 2016 and 2017, the BLM will process 7 renewable energy projects (5 solar and 2 geothermal) representing 1337 MW, or enough electricity to power over 400,000 homes.

Current waste management system at Doug Jernigan Farms, a three-generation family farm that, a few months earlier, refinanced the facility to add a first of it’s kind, in the nation, swine-turkey waste to renewable energy system (not seen), with the assistance of the U.S. Department of Agriculture (USDA) Rural Development (RD) Renewable Energy for America Program (REAP) loan guarantee in Mt. Olive, NC, Tuesday, Nov. 10, 2015.
Typical systems separate methane gas for energy, solids are disposed or repurposed and liquids are cleaned. This new system addition takes the watery manure effluent to a new and as Mr. Jernigan say’s “prolific profit” producing state through savings and sales. “There is an opportunity for the farm to make money doing a good thing for the environment.”
The system handles about 75,000 gallons of swine and turkey waste effluent each day. Piped to a series of cement holding tanks, mechanical equipment, separate solids, and liquids. The current treatment facility biologically removes ammonia nitrogen with bacteria adapted to high-strength wastewater; removes phosphorus via alkali precipitation; and reduction emissions of odorant compounds, ammonia, pathogens, and heavy metals to the environment. The water is cleaned for reuse in the swine and turkey operations that wash more manure into the cycle of the system.
The new methane reactors (under the framework of what will be a C-span structure) use an endothermic gasifier that heats the waste solids to very high temperatures to the point that they release gases. The clean methane gas will fuel an engine that turns a 300KW electrical generator producing electricity; ethanol will help fuel farm equipment, and resulting potash solids can be used or sold for agricultural fertilizer. Excess amounts of electricity, that the farms cannot use, will be sold and transmitted to the local energy company, for use by residents and businesses; renewable energy credits (REC) are sold to a different energy company.
With a system that eliminates all ammonia and other odor creating compounds, Mr. Jernigan says, “What I’m doing is good for the environment; it’s good for the farm in the respect that you’re getting rid of waste that you’re creating in a high-tech way. There’s no footprint. It’s just gone.”
Doug and Aileen are lifelong farmers and they have three grown children that work in the farm operation. Their farm currently operates a 21,600 finishing farm operation, an eight house turkey operation, a 250 head cow /calf operation. The farm also consists of 2,400 acres of row crop production (cotton, corn, soybeans and wheat).
Doug Jernigan’s grandfather started farming here in 1941, and he continues the tradition with his business that began in 1974.
In talking about the greater potential of this technology and what others should consider, Jernigan says, “I see it as a win-win thing.”

*The treatment system (without the methane reactor) was documented to remove, on a mass basis, approximately 99% of total suspended solids, 98% of COD, 99% of TKN, 100% ammonia, 100% odor compounds, 92% phosphorus, 95% copper, and 97% zinc from the flushed manure. Fecal coliform reductions were measured to be 99.98%
