Battery Storage Cost < $50/kWh by 2025

Chinese wind energy and battery company Envision predicts that battery storage cost will drop below $50/kWh by 2025. This would imply e-vehicle battery with a capacity of 40 kWh and range of 500 km for less than $2,000. And less than $100/kWh by 2020.

Lithium Werks to Build 8 GW Battery Factory in China

Dutch entrepreneur Kees Koolen, the man behind booking.com, is now embarking on bigger projects with his new company Lithium Werks, that is building an 8 GW battery factory in China. The project kickoff was attended by the Chinese and Dutch prime ministers in The Hague. Eventually the factory will have an annual production rate of 500 GWh by 2030. The focus will be on lithium iron phosphate batteries with the size of shipping containers, not on the saturated car batteries market. 10 more factories are planned until 2025, for starters one in Mexico and yet another in China. Annual capacity 1 GW.

Additionally a battery R&D center will be set up in Twenthe, next to an old airstrip. Koolen expects to employ 2000 engineers there by 2025.

What does Nm3/hr mean? Normal Meter Cubed per Hour. Unit used to measure gas flow rate. The ‘Normal’ refers to normal conditions of 0degC and 1 atm (standard atmosphere = 101.325 kPa) – for practical purposes this is rounded to 1 bar.

Efficiency Breakthrough Lithium-Ion Batteries?

Dendrites are the enemy of Lithium-Ion batteries

Lithium-Ion batteries could be far more efficient, were it not that they need to be “sabotaged” on purpose, by “diluting” the cathode with graphene in order to prevent the growth of stalactite-like structures called dendrites on the cathode surface, see picture. Dendrites eventually cause the battery to fail, so this outgrowth needs to be prevented with comes at the cost of storage capacity up to a factor of 10.

Researchers at Drexel University, Tsinghua University in Beijing and Hauzhong University of Science and Technology in Wuhan, China have developed an approach to eliminate the need for graphene by working with nanosized diamonds added to the electrolyte inside the battery. This suppresses dendrite growth at least during the first 100 charge-discharge cycles.

Commercial applications are probably several years away.

Ocean Wave Energy in China

Yee Ter Energy Group had researched and developed Ocean Wave Energy for 10 years. This video was created in year 2015 at Qingdao Bay, China. The power plant was being tested as in the video and it successfully generated electric power. This Ocean Wave Energy has Patent Certificate in USA, Japan, South Korea, New Zealand, Germany and Australia. The power plant used the continued ocean waves as the source to generate electricity through its turbine and power generator. It does not require any raw material. It does not produce any pollution. It does not have negative impact to citizen, environment and does not cause global warming.

China to Install 403 GW New Wind Capacity in a Decade

[source] Top 10 distribution of global installed wind power

Currently China has installed 169 GW of wind power, all onshore. According to the renewable energy analysts MAKE Consulting China will add 403 GW new wind capacity between 2020-2030. Note that the total average EU electricity production from all sources is 360 GW alone, although it needs to be remarked that real wind power is ca. 25% of name plate power.

Nevertheless, China, the giant that is awakening.

China Threatens Philippines With War Over South China Sea

[source] The near future, “People’s Liberation Army” storming the beaches of the Philippines?

China’s president warned the Philippines that it would go to war if Manila insisted on enforcing an international arbitration decision rejecting China’s claims over disputed areas of the South China Sea, the Philippine president said in a televised speech on Friday, May 19.

Xi’s threat was unmistakable. This was Xi’s message: “We’re friends as long as you accept the fact that the South China Sea is ours, all of it including the portion you call the West Philippine Sea. As long as you accept this, we will provide you with generous loans to fund your infrastructure projects. But if you drill for oil there, we will declare war on you.”

Philippines president Duterte going public and spilling the beans about Chinese threats, possibly in an attempt to seek international (read: American) help, after the UN has declared Chinese claims null and void?

The reason for this sudden aggressive tone could be the successful Chinese effort to begin to continuously mine methane hydrates, 9 days earlier in the South China Sea. Estimates of 150 billion cubic meters of natural gas equivalent, that is 50 years Chinese oil consumption equivalent. An additional advantage would be that China could shift from dirty coal to natural gas, alleviating Chinese cities pollution.

China Claims Breakthrough Methane Hydrates Mining

Chinese authorities claim to have achieved a major breakthrough in mining methane hydrates in the form of ice from the floor of the South China Sea (SCS), that could lead to a global energy revolution. The fuel was discovered in 2007 but for the first time China is able to mine it in a continuous process from a floating rig in the SCS. Depth: 1,200 m. Since production began on May 10, 2017, 120,000 m3 pure gas-hydrate has been extracted. Japan reported similar successes.

The US-DOE estimates that global methane hydrates reserves could be bigger than all other sources of fossil fuel combined. However, mining of methane hydrates is potentially environmentally dangerous, because methane is one of the worst green house gasses.

Floating Solar in China

[source]

An artificial lake located near Huainan, Anhui, China, was used to install 40 MW worth of floating solar panels. The lake was a result of abandoned coal mining activities in the past. Advantages floating solar: cooling of the panels, no land use, which is important for overcrowded countries like China.
