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.
If you can prove something like a hydrogen society can work in a city like Tokyo, then it’s a matter of how do they scale it, how do the Japanese ensure that all the ancillary consequences have been addressed, and you only really do this by testing it out.
Japan is moving faster than expected toward an hydrogen energy future. Prime Minister Abe has become a vocal advocate for hydrogen – both to stimulate developments in technology and to help the resource-poor nation lower greenhouse gases. With Japan relying more on fossil fuels since the shuttering of most of its nuclear reactors after the Fukushima disaster almost six years ago, it’s a push that’s gained more urgency.
Toyota is at the forefront of Japan’s efforts to use hydrogen and fuel cells to power cars, heat homes and keep factories running. Other companies pursuing the technology include Panasonic Corp, Toshiba Corp and JX Nippon Oil & Energy Corp. Read More
If this large-scale storage of renewable energy in liquid ammonia succeeds, communities can cover long low wind and solar energy periods
The Battolyser, which will be used as a super battery in a gas power plant, is becoming a reality.
For the first time, TU Delft researchers led by Prof. Fokko Mulder have produced an integrated battery electrolysis system – known as a ‘battolyser’ – that can not only store or supply electricity efficiently as a battery but can also split water into hydrogen and oxygen using electrolysis.

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.
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
The City of Los Angeles took a significant step toward realizing its global leadership potential. Mayor Garcetti released LA’s first-ever urban sustainability plan: the pLAn.
LA City Council members Paul Krekorian and Mike Bonin coauthored legislation for a fast route to 100% renewables for LA. With an appreciative nod from the Sierra Club, the news reported at 11district.comfollows:
“LADWP is on the verge of making significant investments in its infrastructure, and with that 100-year-old power system in need of significant upgrades, the city has an opportunity to re-create its utility in a way that recognizes the potential for a fossil-free future, demonstrates global leadership in its commitment to clean energy, and protects ratepayers from the increasing costs of carbon-based fuels.”
Under the current plan, emissions are expected to drop. Under a new plan, they could drop to zero!

Tehachapi is nominally a wind energy-related project attached to the 4.5 GW. 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.
This blog focuses on the Borrego Springs, Tehachapiand and Notrees energy storage projects and examines the long-term impact that they will have on the future project pipeline in the US.
According to the Energy Storage Association’s US Energy Storage Monitor, 60.3 MW of storage was deployed in the third quarter of 2015, a twofold year-on-year increase.
Sam Molenaar believes that, with further optimization, the bacteria-based battery could rival the performance of lithium-ion batteries at a lower cost and with greater safety.
A rechargeable battery driven by bacteria? Lithium-ion batteries are limited by safety issues, high costs and other factors. Sam Molenaar and his colleagues from Wageningen University wanted to come up with a less expensive, more sustainable solution.
The research team combined two separate microbial energy systems. One system used bacteria to form acetate from electricity, while the other one converted the produced acetate back into electricity. Read More
Yesterday, US Secretary of State John Kerry announced a doubling of the US payments on climate aid from 430 to $ 860 million in 2020. With this gesture of goodwill the White House hopes for a possible signal from the developing countries.
Yesterday, the new concept agreement was finished. Just two hours later than promised.

More than three quarters of the discussion have been resolved.
COP21: Rallies call for Paris climate change action
Will the negotiations in Paris lead to an international climate agreement? The question seems not to be whether the negotiations lead to an agreement but what bottom line, the results of the agreement will be.
Five questions about the climate issues. Read More
Berkeley Earth has just released analysis of land-surface temperature records going back 250 years, about 100 years further than previous studies. The analysis shows that the rise in average world land temperature globe is approximately 1.5 degrees C in the past 250 years, and about 0.9 degrees in the past 50 years.
With 195 participating countries and 3000 journalists we can expect a lot of news from Paris during the next days.
In advance, a summary of the top in figures. Read More
Businesses have a major role to play in driving low-carbon growth
Fear is a bad counselor, when it’s about terrorists and refugees. But it’s a welcome guest at the big climate summit that begins today in Paris. Global warming needs to be stopped, we are running running out of time.

Already 86 large enterprises have signed the LCTPi. Read More
the Power-to-Gas (P2G) approach can facilitate a transition from natural gas to a ‘green’ mixed gas by making use of both of the existing energy grids on a global scale
Power-to-Gas is the process of converting surplus renewable energy into hydrogen gas by rapid response electrolysis and its subsequent injection into the gas distribution network. One of the most promising energy storage systems to storage renewables into the existing EU gas infrastructure.
The hydrogen produced is injected into the natural gas system to displace natural gas, so reducing greenhouse gas emissions and reliance upon fuel imports.
If the power is derived mainly from renewable power sources, only low-carbon hydrogen will be produced. Thereby the Power-to-Gas (P2G) approach can facilitate a transition from natural gas to a ‘green’ mixed gas by making use of both of the existing energy grids on a global scale.
