Electrovaya’s New Battery Technology Adds Thermal Stability

Electrovaya’s new battery technology increases the ability of Li-Ion batteries to withstand the higher temperatures of today’s powerful batteries

Electrovaya and it’s new German acquisition own the patent on a new battery technology that will make all Lithium-Ion batteries better and safer by increasing the ability of Li-Ion batteries to withstand the higher temperatures of today’s more powerful and energy dense batteries.

Thermal stability is everything when it comes to creating batteries that are more powerful and more densely packed — as in the large battery packs found in electric vehicles, for one example.

Electrovaya’s fully embedded ceramic material withstands significantly more heat than conventional materials used to electrically isolate battery components and are lighter, safer and cheaper than present-day industry standards.

The Lithium-Ion battery business — already a global industry, will be a $70 billion business within 10-years and it looks like Electrovaya intends to dramatically improve the performance and safety of all Li-Ion batteries, as excess heat and how to contain it, has always been the nemesis of the battery industry. Not to mention incrementally lowering the weight of each Li-Ion cell — an important factor in large batteries such as those found in electric vehicles.

Note that the TESLA P100 battery (which is actually a 100kW battery pack consisting of 8,256 individual rechargeable Lithium-Ion cells in the Panasonic 18650 format, for a total output of 102.4kW) weighs well over 1,200 pounds. A weight savings of 10% (for example) adds up to lower total battery pack weight and longer range for such vehicles.

UK Leads G7 in Combined Metric of Economic Growth / CO2 Cuts

Reposted from Letter to Britain

by John Brian Shannon

A new Energy & Climate Intelligence Unit report confirms that Britain has been the most successful G7 nation over the last 25 years on the combined metric of growing its economy and reducing greenhouse gas emissions.

In the 25-years since 1992 when clean air and the corresponding lowering of healthcare spending suddenly became an important policy, Britain grew its per capita GDP by 130% while lowering GHG emissions by 33% — proving that a country can simultaneously grow their economy AND lower greenhouse gas emissions.

Comparatively, Japan grew its per-capita GDP by 83% while increasing its per-capita emissions by 10.5% — making it the worst performer of all the G7 nations. (Not to pick on Japan which has the most difficult population pyramid demographic problems of any nation on the planet)

“It’s really time to slay once and for all the old canard that cutting carbon emissions means economic harm.

As this report shows, if you have consistent policymaking and cross-party consensus, it’s perfectly possible to get richer and cleaner at the same time. Britain isn’t the only country that’s done it – it’s true for most of the G7 – but we’ve clearly been the best of the bunch.

There are signs that these successes are now transferring to the rest of the world.

Globally, emissions have been flat for three years while world GDP has grown by 8%. But science indicates this isn’t enough to fulfil the objective of the UN Convention and prevent ‘dangerous’ climate change – for that, emissions need to start falling soon.

This study should give confidence that with good policies, it’s achievable.” — Richard Black, director of the Energy and Climate Intelligence Unit

And in the United Kingdom, Scotland has led the way on the switch from coal to renewable energy and it rightly deserves many of the accolades handed to the UK over the ongoing clean air success story, while England and Wales deserve much of the credit for growing the UK economy. As usual, Northern Ireland is ‘holding its own’ and although it is presently caught in the middle of an election cycle it seems that it might ramp-up to follow Scotland’s environmental success, post-election.

The Road to Decoupling: 21 Countries Are Reducing Carbon Emissions While Growing GDP (World Resources Institute)


By far, the biggest reason UK emissions have dropped in every decade since WWII is a HUGE shift away from coal. At one time, almost 100% of Britain’s electricity was sourced by brown or black coal. Some of which was replaced by hydro-power, and later, by nuclear. Eventually, even more coal-fired capacity was replaced by natural gas, and most recently, by renewables.

The inexorable march away from coal-fired generation in the UK resulted in cleaner air. It is by far the biggest factor in Britain’s ongoing clean air success story.

Still, it’s not enough progress. Scotland has set the standard that the rest of the UK should follow — which will take strong leadership in the House of Commons.


The Way Forward for Clean Air, Lower Healthcare Spending, and a Thriving Economy for Britain

There are many ways to accomplish those goals and everything has its own particular cost. But two pathways jump out as the most beneficial per pound sterling.

ONE: Continue to replace coal-fired power generation with any other power generator. Yes, everything else burns cleaner than coal! Burning home heating fuel is cleaner than coal. Natural gas-fired power generation can be up to 1-million times cleaner than burning some grades of brown coal. Even upgrading coal-fired power generation from brown coal ‘lignite’ fuel to black coal ‘anthracite’ fuel results in astonishing improvements in air quality.

Fortunately, this is the (unevenly applied) default in the United Kingdom, which, when combined with the solid and thoughtful policies of Scotland and Wales, results in cleaner air, lower healthcare costs, and boosts economic growth via lower energy prices.

Record UK wind generation lowers electricity prices (Power Engineering)

TWO: In addition to everything mentioned above, the other low-hanging fruit leading towards cleaner air, to lower healthcare spending and to boost economic output (by lowering energy costs) is via energy-efficiency.

Prime Minister Theresa May should recognize that no matter how cleanly we can generate one GigaWatt of electricity, energy-efficiency equal to one GigaWatt is many times cleaner — and such improvements are typically simple and cost-effective.

Imagine a UK government policy that lowers primary energy consumption (demand) by 30% across-the-board over the next 5-years.

That’s possible with the right policy, and infinitely cheaper than adding the exact same amount of energy production capacity (demand) to the grid.

Cheaper, by orders of magnitude. In fact, the Hinkley Point C nuclear power plant construction could be cancelled AND other proposed power plant projects could be shelved for at least a decade with that much efficiency added to the grid.

Simple programmes get the best results

If the UK government added an energy-efficiency programme shared by three government entities, costs and (importantly) accolades would be shared between them.

The Department of Energy & Climate Change, the Secretary of State for Business, Energy and Industrial Strategy, and the Department for Communities and Local Government, would gain support from voters and expats by supporting a national energy-efficiency programme consisting of a £100 per capita credit on energy-saving electronics and materials.

For a business that employs 5 people, that’s a one-time credit of (up to) £500 towards energy-efficiency at that business, which will buy A TON of efficiency and thereby lower energy consumption/energy bills for that company.

All else being equal; Are those business owners more likely to vote Conservative in the next election? I would have to say, Yes.

Obviously, those 5 employees also live near their workplace and use electricity at home. Therefore, they too should receive a one-time (up to) £100 per capita credit at the hardware store for the purchase of LED or other energy-saving lights, smart thermostats, weather-stripping, insulation, receptacle gaskets and other energy-saving electronics or materials.

Each of those 5 people will now save significant amounts on their monthly electricity bill.

Again, all else being equal; Are those homeowners or tenants more likely to vote Conservative in the next election? The answer is likely to be affirmative if the present government decides to save each one of them, tens or hundreds of pounds per year on their annual electricity bill.

It sounds expensive until you consider the cost of adding 30 GigaWatts to the UK grid to cover wasted energy vs. spending a much smaller amount to conserve the same amount of energy.

There is simply no comparison. Energy-efficiency wins every time, and it’s cheap in relation to the costs of building new generation capacity.

A £100 per capita energy-efficiency credit for the UK is the way forward for clean air, lower healthcare spending, and a thriving economy for Britain (via lower energy costs) and pound for pound, nothing else comes close to accomplishing those goals at such a comparatively low spend.

The Inevitability of Renewable Energy

by John Brian Shannon

Renewable Energy costs have fallen to such a level over the past ten years that it now competes, sans subsidies in some locations, against heavily-subsidized fossil fuel power generation, nuclear power generation and hydro-electric dams which receive billions of dollars of subsidies every year.

Many people might be surprised to hear that; It certainly hasn’t been reported by a majority of the mainstream media.

Fuel Subsidies: The Elephant in the Room

Historically, the reason given for subsidies was to allow new industries to move past the typically turbulent first few years of operation, until they reached a sort of ‘steady-state’ when the business model was fully functional and profits alone could sustain the business, yet the conventional energy industries that have been an important and profitable part of the energy sector are still receiving billions in subsidies annually — while the new kid on the block finds that their much-smaller subsidies are tapering.

Since the first oil wells were struck in Pennsylvania in the late 1890’s, subsidies of one form or another have been an important factor in our primary and secondary energy world.

After the coal price crash in 2014 and the oil price crash of 2016, total volumes of coal and oil deliveries dropped significantly, while the actual subsidy regimes in place for those fuels did not change significantly. Therefore, any perceived subsidy drop must be viewed in the context of lower production which affected the total subsidy amounts received by those industries.

At the same time, many countries that have supported the development of renewable energy have lowered or eliminated their renewable energy subsidies. Germany is an telling example of an early-adopter that discontinued their renewable energy Feed-In Tariffs, while the United States has canceled their lucrative Production Tax Credit for wind energy projects.

And nobody seems to notice! Renewable Energy installations are continuing, the rate of new RE installations is at an all-time high and increasing on a month-to-month basis.

Renewable Energy vs. Conventional Energy

Global Energy Subsidy Totals WEO-2016

The value of subsidies to fossil fuels fell sharply in 2015 to $325 billion, down from almost $500 billion in 2014. Lower fossil-fuel prices were the main reason for the drop, but lower prices have also given additional impetus to pricing reforms in many countries, both fossil fuel importers and exporters. Even with the drop in 2015, the amount going to subsidise fossil fuels is still more than double the $150 billion spent on subsidies to renewable energy.

Renewable energy is the growth story of WEO-2016

In our main scenario, nearly 60% of all new power generation capacity to 2040 comes from renewables and, by 2040, the majority of renewables-based generation is competitive without any subsidies. In a scenario compatible with 2°C, significantly faster growth means that, in the four largest power markets (China, the United States, the European Union and India), variable renewables become the largest source of generation. — International Energy Agency | Fact Sheet: World Energy Outlook 2016

“According to a new report from the U.S. Department of Energy, solar power employs more people than coal, oil and gas combined.

Last year, solar power accounted for 43 percent of the Electric Power Generation sector’s workforce, while fossil fuels combined employed 22 percent. The statistic will be welcomed with open arms by those trying to refute Donald Trump’s assertion that renewable energy projects are bad news for the U.S. economy.

Around 374,000 people were employed in solar energy, according to the report while generation through fossil fuels had a workforce of just over 187,000. The solar boom can be attributed to construction work associated with expanding generation capacity.

The report states that the employment gap is actually growing with net coal generation decreasing 53 percent over the last 10 years.

During the same period of time, electricity generation through gas expanded 33 percent while solar went up by an impressive 5,000 percent.” — Niall McCarthy | Statista

Power to the People!

Conventional energy producers in business for over a century can’t seem to survive without huge subsidy amounts — while Renewable Energy barely topped $150 billion globally, and those RE subsidies are now disappearing.

On the Economics of Wind and Solar Power

Originally published at The Beam | On the economics of wind and solar power — by Lion Hirth

“Many hope that wind and solar power will eventually become economically competitive on large scale, leading the way to a global low-carbon economy. Are these hopes justified?”

November’s COP22 climate summit of Marrakech gave climate policy fresh tailwind, after the blow of Donald Trump’s election. Even without a strong global treaty, national climate policies are multiplying — at least a certain type of policies. While the policy that economists often recommend — putting a price on greenhouse gas emissions — remains patchy, as a recent World Bank report shows, subsidies for renewable energy are booming: no fewer than 145 countries support renewables today. Germany’s Energiewende is a prominent, but not the only example: Obama’s Clean Power Plan features renewables as a centerpiece of climate policy, India’s National Solar Mission includes a 100 GW solar power target. In addition China is said to be considering a 200 GW target, and Morocco has announced the building of the largest solar power facility on the planet. Nearly half of all newly added electricity generation capacity was based on renewables. In ten countries, wind and sun deliver more than 10% of electricity consumed. These includes Denmark (43%), Portugal (24%) and Spain (23%).

Many hope that wind and solar power will eventually become economically competitive on large scale, leading the way to a global low-carbon economy. Are these hopes justified?

On the cost side, the economics of renewables look impressive. The costs of wind power have dropped significantly. On average, wind now generates electricity at $70–80 per Megawatt-hour (MWh) globally, as reported by the two international think tanks IRENA and IEA. Ten years ago, a roof-top solar array for a single family home cost more than $50,000 — today it sells for less than $14,000. (America’s LBNL and Germany’s Fraunhofer ISE provide more data.) Germany, which receives less solar radiation than southern Canada, now generates solar power at $90 per MWh. The United Arab Emirates have tendered a solar power station for $58 per MWh and recent auctions in Chile, Peru and South Africa have resulted in even lower prices.

In some countries, wind and solar power are now cost-competitive with coal- and natural gas-fired power plants, even when carbon emissions are not priced. However, cost structures are very country-specific, and cost-competitiveness is not universal. Renewables tend to be cheaper where it is windy or sunny, where investors have access to low-cost finance, where fossil fuels are pricey, and where emissions are priced. In many places, however, coal-fired power plants remain the cheapest option for producing electricity, driving the renaissance of coal. Still, for renewables to have caught up with fossil plants in cost terms represents a huge success for wind and solar power.

Costs are, however, only one side of the competitiveness equation. The other is value. Merely comparing electricity generation costs between different plant types is misleading, as it ignores the fact that the economic value of electricity from different power stations is not the same. This is because on wholesale markets the price of electricity fluctuates from hour to hour (or even minute to minute). Some power plants produce electricity disproportionately at times of high prices (so called “peaking” plants), while others produce constantly at low prices (“base load” plants). This little detail has striking consequences for the economics of wind and solar power. Paul Joskow and Michael Grubb observed this a while ago.

On the value side, the outlook for renewables is…

Solar Power and Wind Power combine to provide 475,545 U.S. jobs — while Nuclear Power and Fossil Fuel Power generation combine to provide only 255,293 U.S. jobs — but in recent years the Fossil Fuel industry gets 4 times more subsidy than Renewable Energy


Renewable Energy = Clean Air and Twice as many Jobs on 1/4 the Subsidy!


Here is a look at historical U.S. federal subsidies paid from 1918 to 2009 for various energy producers.

What Do Americans Think About Fossil Fuel vs. Renewable Energy?


Solar power and wind power (alone!) employ almost twice as many Americans as all nuclear and all fossil fuel power plants combined, but renewable energy gets only one-quarter of the subsidies in from 2010 onward.

Which might be a factor in the minds of Americans who look forward to renewable energy meeting their future energy demand.

Despite the low subsidy amounts paid to renewable energy in the United States, non-hydropower energy continues on its growth trajectory and it’s now cheaper to build new solar capacity, than to build new coal capacity.


New Solar Now Cheaper Than New Coal


Costs for new solar power plants continue to plummet (without subsidy) vs. new coal power plants (with a small subsidy) is reflected in the Levelized Cost of Electricity (LCOE) per Kilowatt Hour price.

“As early as 2018, solar could be economically viable to power big cities. By 2040 over half of all electricity may be generated in the same place it’s used. Centralised, coal-fired power is over.”Solar has won. Even if coal were free to burn, power stations couldn’t compete — The Guardian


Billions of Gallons of Water Used Monthly by Conventional Energy

Many coal-fired power plants and several nuclear power plants produce well over 1000MW (1 GW) of electricity and it is easy to extrapolate their water usage.

For instance, a 1.6 GigaWatt(GW) coal-fired power plant (for the purposes of this discussion there’s a 1.6GW coal-fired power plant in Texas) uses 1,760,000 gallons of water per hour, while an equivalent-sized nuclear power plant uses 1,280,000 gallons of water per hour.

Meanwhile, a natural-gas-fired power plant producing the same 1.6GW of electricity would consume 480,000 gallons per hour, while a 1.6GW solar or wind power would consume zero gallons per hour.

Of course hydro-power does not consume any water during its decades of reliable power production, water merely falls through turbines and back into the river a bit further downstream — although during the construction of the dam, spillways, and hydro-electric turbine rooms, millions of gallons of water are used to make the concrete.


The Future of Energy in the United States


Renewable generation capacity expected to account for most 2016 capacity additions in the U.S.

The chart below displays total utility-scale capacity additions from 2010 to 2016. For the third consecutive year, more than half of the capacity additions are renewable technologies, especially wind and solar.

From 2013 through 2040, U.S. electricity demand is expected to grow approximately 1 trillion kiloWatt hours(kWh) with natural gas and renewable energy showing steady growth, while coal-fired power generation and nuclear power show slight declines according to the U.S. Energy Information Administration.

If the United States converted their existing coal-fired power generation to natural gas by 2020, the U.S. could easily meet every international and domestic clean air target until 2050 as coal burns 10,000 times ‘dirtier’ (anthracite, or black coal) to 1,000,000 times ‘dirtier’ (lignite, or brown coal) when compared to natural gas.

It goes without saying that if the United States replaced coal-fired power generation with renewable energy, it would surpass every U.S. international and domestic clean air target, lower U.S. heathcare and infrastructure spending by billions of dollars annually, save the U.S. billions of gallons of fresh water per month, provide millions of good-paying jobs for American workers — and prove the United States is still an exceptional power in the 21st-century. Not bad!
