On Feb. 10 in Belfort, President Emanuel Macron announced his vision for the French global energy industry to 2050. He reaffirmed France’s desire to massively develop renewable energies as intermittent sources on top of the baseload provided by the nuclear industry whose revitalization has already made headlines since. Macron claimed they are “the only means to meet [our immediate energy needs] in a profitable and competitive way”. By 2050, the capacity of the French solar park should be multiplied by more than 10 to exceed 100GWp, while the onshore wind capacity could double to reach 37GW. Offshore wind power should also experience a real take-off as France aims to develop and build 40GW over the same period.

The London-based analyst has published a series of clean tech predictions for the year which also highlighted the rising proportion of sub-5MW solar projects in the global market, and cheaper clean energy financing costs even as panel prices continue to rise.

Scientists in the United States developed a lithium-sulfur battery using a commercially available carbonate electrolyte, that retained more than 80% of its initial capacity after 4000 cycles. The group used a vapor deposition process which unexpectedly produced a form of sulfur that did not react with the electrolyte, overcoming one of the key challenges for this battery chemistry.

The EU has been pouring money into European battery manufacturing and recycling projects but has, as yet, been unable to address the critical question of raw materials, according to analyst WoodMac.

Scientists in the United States placed fast charging for lithium-ion batteries under the microscope, finding that charging at higher rates can quickly damage the structure of a graphite anode, causing capacity loss even after a small number of cycles. By identifying the mechanisms causing this performance loss, the group can help point future research in the right direction.

As part of their efforts to bring lithium-ion battery degradation under control, scientists in China have looked to emulate natural defenses many organisms have evolved to reduce oxidation reactions and related damage. With an additive that ‘scavenges’ reactive particles before they can contribute to degradation, the group was able to demonstrate significantly lower electrolyte decomposition in a working battery.

Scientists in the United States pieced together data from hundreds of different sources, looking to establish the key factors that have led to consistently falling prices for lithium-ion technology since their commercialization thirty years ago. They find that public-funded research, primarily in chemistry and materials science, has made the largest contribution to cost reduction. And they offer suggestions on policy and investment to ensure that the research can continue to make these important contributions to reduction in battery costs.

Panasonic said the system is available in the U.S. with storage capacities of 17.1 kWh and 25.65 kWh. The product comes with a floor-standing battery cabinet and a hybrid smart inverter with 4 MPPTs.

Manufacturer Sunlight plans to invest €30 million to add 1.3 GWh of annual production capacity of lead-acid products by the third quarter of next year. The company will also devote €20 million to expanding its lithium-ion battery assembly lines.

Scientists in the U.S. discovered a promising new battery chemistry based on chlorine and table salt. Batteries based on this chemistry can achieve at least six times the energy density of today’s lithium-ion batteries, according to the group that created it. The prototype battery could already be suitable for small devices such as hearing aids, and with further work could be scaled up to larger applications.
