Eliminate hydrogen for better battery performance, scientists say

Scientists at the University of California, Santa Barbara who are working with sodium-ion batteries have found that the unintended presence of hydrogen is to blame for many of the technology’s shortcomings in terms of degradation and performance loss. Keeping hydrogen out of the materials throughout production could allow sodium-ion batteries to achieve performance levels competing with their lithium-ion counterparts.

UK needs 13 GW of DSR, smart EV charging and V2G ramp up for net zero goal

… and it will be quite an effort. The U.K.’s grid operator, National Grid, released a new report on possible energy system transformation pathways, amidst growing public concern over climate change. Ramping carbon emissions reduction targets up from 80% to 100% prompts technical challenges. These can be overcome but will require full alignment of policy effort and individual awareness and decision making.

Japan’s Toray to manufacture battery components in Europe

Japanese materials company Toray has announced plans to open a facility for manufacturing battery separator films for use in lithium-ion batteries. The factory is expected to begin operations in July 2021 and will increase Toray’s production material for the component by around 20%.

Lithium-ion recycling rates far higher than some statistics suggest

While it is often stated only 5% of lithium-ion batteries are recycled, a review of research into the second life and recycling of lithium-ion batteries suggests that is a gross understatement. A new study found almost 100,000 tons of waste batteries were recycled last year – about half of what reached end-of-life.

The United States is headed for a battery breakthrough

A new report by the Energy Information Administration projects U.S. installed battery storage capacity will reach 2.5 GW by 2023. Florida and New York are set to pave the way as massive projects in each state will account for almost half the coming capacity.

‘True grid parity about more than electricity price’

The head of Mercom Capital says solar has a long way to go before it can stand without policy support. Effective grid parity will only be achieved when the cost of PV electricity factors in the expense of grid upgrades and the storage systems its intermittent nature requires, says Raj Prabhu.

Australia will need 15 GW of utility scale storage by early 2040s

Increased storage and strategic transmission development will be needed to ensure the most economic and lowest risk transition of Australia’s energy system, the Australian Energy Market Operator said in its latest study. In 20 years’ time, the need for storage will be at a scale not seen before in the national electricity market, and pumped hydro and distributed storage are set to play major roles in lowering electricity prices and building a reliable and resilient power system.

Grid data transparency vital to making the case for renewables in Vietnam

With a glut of solar capacity having come online this year, cheaper financing would help keep some of that momentum but policymakers cannot be persuaded of the economic benefits of clean energy unless state-owned utility EVN opens up.
