Harvard new nontoxic Battery

Harvard new nontoxic Battery Team

By modifying the structures of molecules used in the positive and negative electrolyte solutions, and making them water soluble, the Harvard team was able to engineer a battery that loses only one percent of its capacity per 1000 cycles.

Harvard scientists have developed a new flow battery which stores energy in liquid, works 10 years without energy loss and is much safer than lithium-ion batteries.

After a few years of heavy use, most lithium-ion batteries suddenly loose a lot of storage capacity. You surely recognize this from your smartphone, but that’s also a problem for energy storage which should last a very long time to store solar energy. Scientists at Harvard University have found a possible solution.

The new technology promises a battery definitely lasting ten years without losing much capacity. The solution is applied to a so-called flow-battery. The flow battery stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.

Power Storage: the options

Power Storage: the options

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

Can we repurpose EV batteries?

 Can we repurpose EV batteries?

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

Loss-free Solar Heat Battery

Solar Heat Battery

A chemical reaction transfers the absorbed heat into a special system, where it is stored. This system consists of a container that is mostly filled with salt, and a little water.

Until now, solar heat couldn’t be stored without several loss.

But this is gonna change. 

TNO presents a battery which can be used for solar heat storage without losses.

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

Energy Storage Option: Smart Water Heaters

Energy Storage Option: Smart Water Heaters

CEO, Olin Lagon & Operations Director, Nicole Brodie

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.
