In Stephentown, New York, Beacon Power has build a 20MW / 5MWh plant consisting 200 carbon fiber FlyWheels. These FlyWheels make between 3000 and 5000 cycles per year through their input in the frequency regulation market.
Power Storage: The world does have a lot of options but its still expensive.
In order to manage supply and demand our renewables, we need to store the electricity when the wind is blowing hard and the sun shines brighter than there is demand.
For instance, Berkeley wind energy experts suggest a likely average cost reduction of between 24% to 30% by 2030 and 35% to 41% by 2050 across the three wind applications studied — onshore wind, fixed-bottom offshore wind, and floating offshore wind.
There is a further 10% chance that cost reductions could be more than 40% by 2030 and more than 50% by 2050. BetterWorldSolutions offers you a number of actual, technically available options. Read More
Vattenfall: Our stated goal is to integrate this battery storage facility into the energy system and to give a large number of similar small local facilities access to the market through electricity trading
2nd Life project with used BMW batteries for balancing the grid. Vattenfall, BMW and Bosch test electricity storage with repurposed EV batteries in Hamburg.
2,600 used battery modules from over 100 electric vehicles are being merged to form a large electricity storage facility in Hamburg
The stored energy is available within seconds and can help to keep the electricity grid stable
Cordelia Thielitz, General Manager Bosch Energy Storage Solutions: Electricity storage systems are a key success factor for the new energy landscape.
V-Storage started a pilot using old batteries from busses as an energy storage system. The ‘old’ batteries are placed in a large container. They intent to use the stored energy to electrify busses and to increase the Grid Balance. The pilot will start in January 2017.
In four or five years, the batteries in the roughly one and a quarter million EVs currently on the road are going to start to wane. EV owners will either replace them, or replace the cars entirely.
That means we’ll have a lot of used batteries (with plenty of life left in them) but which are no longer suitable for EVs. What to do?
One possibility is repurposing them to serve as grid-connected energy storage.
Storage is valuable to the grid for many reasons, including its ability to smooth out fluctuations in supply, allowing for more integration of variable renewable energy. Read More

The heat is held in the salt, and the chemical reaction that trapped it there is reversed to release the heat again when it is needed. ‘It’s all about hydration and dehydration, or wetting and drying salt.
Energy producing buildings
TNO succeeded in developing a solution to store the energy surplus of energy producing buildings in a working lossless heat battery. Read More
In the body of the study it becomes clear that FCVs do not beat internal combustion engines (ICEs) by much in equivalent fuel economy, And they are not much better in greenhouse gas emissions either, particularly in the liquid hydrogen versions, because of the energy required to transport and compress the hydrogen.
Hydrogen fuel cell cars appear to be making a comeback. But is this real? The comparison in question includes discussion of:
the wider process behind producing hydrogen fuel
the production itself
the transportation of the fuel
The future is a bit cloudy for hydrogen fuel cells (HFC), as electric vehicles have developed quickly and taken significant market share. Read More
A year ago, Hawaiian Electric began deploying smart water heaters as very first residential behind-the-meter real-time energy storage.
Hawaii is transitioning faster than anywhere else from a huge and risky over dependency on imported fossil fuels, particularly for electricity generation.
A new use for water heaters, storing energy for a utility company.
Historically, storage technologies have not been widely used because it has not been cost competitive with cheaper sources of power, such as fossil fuels. However, given the recent decline in cost as well as improved storage technologies, storage has become an option that is able to compete.
Hawaii’s transition to 100% renewables
Under Hawaii’s Renewable Portfolio Standard (RPS), each electric utility company must meet the following percentages of “renewable electrical energy” sales:
30% of its net electricity sales by December 31, 2020
40% of its net electricity sales by December 31, 2030
70% of its net electricity sales by December 31, 2040
100% of its net electricity sales by December 31, 2045
Energy storage and smart water heaters
Shifted Energy is a Hawaii-based demand response (DR) aggregator that develops, installs, maintains, and operates smart grid DR solutions that leverages the energy and thermal storage capacity of grid interactive water heaters (GIWH).
Shifted’s solutions connects water heaters to smart systems allowing heaters to cycle on or off based on real time grid needs for increased or reduced aggregate power consumption.
Cycling heaters on can absorb excess intermittent renewable power such as daytime PV production, as well as providing ancillary grid services such as frequency regulation.
Shifted creates a unique software layer to add energy efficiency algorithms and systems to reduce participant energy bills.
The value of smart water heaters is the substantial load with significant usage during the critical late afternoon ramp. This entire first ever deployment – anywhere – of Grid Integrated Water Heaters (GIWH) technology would not have happened without Olin Lagon and his company Shifted Energy.
Olin is a software architect with a string of patents who has a long history of social responsibility. Born and raised in Hawaii’s public housing this founder and former director of non-profit Kanu Hawaii is putting his love of technology directly to work. Olin formed Shifted Energy and joined the Energy Excelerator specifically to help leverage GIWH.
He is convinced that GIWH is the single most cost-effective and scalable renewable technology that will directly benefit all stakeholders. Working directly with Hawaiian Electric, Olin and the Energy Excelerator helped fund this first deployment in western Oahu and Olin took personal responsibility (“kuleana” in Hawaii) working hands-on over the past year with plumbers and electricians during installation and start up.
Tehachapi is nominally a wind energy-related project attached to the 4.5 GW Tehachapi Wind Resource Area, although in actual fact the plant was conceived as a two-year test bed for a wide range of potential grid applications. When it opened, in September 2014, it was credited with being the largest battery storage project in the North of the US, with 604,832 Li-ion cells housed in 10,872 modules.
Everyone knows California and New York do have behind-the-meter energy storage at a large scale. But there are some sleeper states where the economics already work.
