Rarely has such a crucial enterprise for the future of human civilization led to such little commercial success.

Long-duration energy storage holds great potential for a world in which wind and solar power dominate new power plant additions and gradually overtake other sources of electricity. Wind and solar only produce at certain times, so they need a complementary technology to help fill the gaps. And the lithium-ion batteries that supply 99 percent of new storage capacity today get very expensive if you try to stretch them out over many hours.

The problem is, no clear winner has emerged to play that long-duration role. Here at Greentech Media, we’ve spent years covering the contenders, which range from quixotic defiers of the laws of physics to understated, scientifically minded strivers. The makeup of this roster has fluctuated to the rhythm of bankruptcies and new investments.

Plenty of options technically “work.” The question is, do they work with an acceptable price point and development cycle, and can the businesses providing them stay afloat long enough to actually prove that? That last step has been hard for companies to fulfill, insofar as in previous years there were practically no places to actually sell this stuff.

10 Predictions for the Solar and Storage Market in the 2020s

Branding and reputation will be increasingly important in the energy storage market.
Paul Dailey

The solar-plus-storage market is evolving rapidly and will look completely different a decade down the road. What can we expect on the way to 2030? Here are 10 predictions.

All-in-one systems will be the new normal

1. Lots of storage
Batteries will be incentivized or mandated for practically every new solar PV system across the U.S. by 2025. As more homeowners and businesses deploy PV systems to reduce their electricity bills and ensure backup power, simple net metering will increasingly be replaced by time-of-use rates and other billing mechanisms that aim to align power prices with utility costs. We already see these trends in California and several states in the Northeast.

2. System costs will increase with the shift toward batteries
Solar systems with batteries are going to be about twice as expensive as traditional grid-direct installations, so in that sense, we will see actual costs increase as the mix shifts toward batteries. But while system costs will go up, we need to be careful to parse the actual equipment and soft costs from the consumer’s cost net of tax credits and incentives. Equipment costs for batteries and other hardware are generally flat to slightly down.

US Storage Industry Achieved Biggest-Ever Quarter and Year in 2019

States such as Hawaii (pictured), Nevada and Arizona are building large-scale solar-plus-battery plants to meet peak electricity demand.

By Julian Spector
The U.S. energy storage industry capped off its biggest year of installations with its largest single quarter in Q4.

U.S. energy storage installation topped 522.7 megawatts/1,113 megawatt-hours in 2019 as a whole and 186.4 megawatts/364.2 megawatt-hours in the fourth quarter, according to the newly released Energy Storage Monitor 2019 Year in Review, produced by Wood Mackenzie and the Energy Storage Association. 

For years, those in the industry have argued that the ability to store and release electricity nearly instantaneously offers great operational benefits, not just for the adoption of intermittent renewables but also for more efficient grid operations.

The latest numbers suggest that this argument is starting to resonate as utilities across the nation contract for large battery plants and an unprecedented number of homeowners seek solar-battery combinations to keep the lights on in an outage.

Webinar: NREL Introduction to REopt Lite Open Source

Tuesday, March 17, 1 - 2pm ET
The REopt Lite web tool helps building owners evaluate the economic viability of grid-connected PV, wind, and battery storage at a site; identify system sizes and battery dispatch strategies to minimize energy costs; and estimate how long a system can sustain critical loads during a grid outage. In this webinar, we will review REopt Lite Open Source, the latest addition to the suite of ways you can use REopt Lite for research, analysis, and project development. REopt Lite Open Source allows programmers to explore the source code to see exactly how the model works, add custom capabilities, and work with NREL to implement new features. This webinar is hosted by NREL.

The Solar Foundation: National Solar Job Census 2019

As of 2019, the National Solar Jobs Census found:

The National Solar Jobs Census 2019 is The Solar Foundation’s annual report on the size and scope of the American solar workforce. Based on a rigorous survey of solar employers, it is the most comprehensive analysis of solar labor market trends in the United States.

The United States has 249,983 solar workers, defined as those who spend 50% or more of their time on solar-related work. The solar workforce added more than 5,600 jobs nationwide from 2018 to 2019.
American solar jobs have increased 167% over the past decade, adding 156,000 jobs. In the five-year period between 2014 and 2019, solar employment increased 44%, five times faster than job growth in the overall U.S. economy.
Solar jobs increased in 31 states in 2019. Florida led the nation for the number of jobs added, followed by Georgia, Utah, New York, and Texas.

Webinar: Building the Solar Schools of the Future, Today

Monday, February 24th, at 10:00AM  PST

Why do we make solar schools appear to be so daunting?

The conversations surrounding solar schools and more generally responses to climate change give the impression that implementing renewable energy on a massive scale is a daunting, if not impossible challenge. This at least is the impression from reviewing media and social media. My question is why do we approach the task of reorienting our economy in general and implementing solar schools and other facilities with this bias? Are solar implementation and financial analysis of renewable energy systems that complicated and too expensive to implement on a mass scale?

My response is a resounding no.  The webinar, based on my book, The Inevitable Solar School: Building the Sustainable Schools of the Future, Today (Rowman & Littlefield, 2019), describes solar schools at or approaching zero energy that are being built at construction costs equal to or below regional cost average. These schools then have lower operating costs.The webinar provides examples of school solar financial analysis and implementation that should be ordinary and must become routine if we are to battle climate change on a mass scale.

10 Rooftop Solar and Storage Predictions for the Next Decade

Don't expect a unifying app for all your home's energy systems any time soon, the author writes.
By Barry Cinnamon

Predicting the future is easy; getting the exact timing is very hard — especially with all the emerging technologies and requirements facing the solar and storage industry.

So this year I’m giving myself a whole decade to get these behind-the-meter energy system predictions mostly right.

1.Storage will be standard with solar....
Solar-only installations will become the exception rather than the rule. Changes with net metering, unreliable utility power, lower battery costs, grid-services capabilities and energy management features will drive customers toward selecting more full-service solar and storage offerings. By necessity, the skill set of solar contractors will expand to backup panel and communications cable wiring, as well as complicated commissioning and configuration procedures. Timeframe: now, accelerating over the next five years.

2. ...Which means new cost metrics will be needed
For 20+ years, the solar industry has been measuring costs based on dollar-per-watt capacity and dollar-per-kilowatt-hour generation. But adding batteries to a PV system increases the cost and confuses the energy savings calculations. I’m waiting for the gurus at NREL and LBNL to figure these new metrics out.
