Battery costs have fallen 97% since 1991, claim MIT researchers

Academics reviewed the historic price development of lithium-ion batteries and found the accepted model does not accurately reflect the full cost decline and technological improvement which has taken place. With more data points to compare, the team found batteries had improved even more than previously assumed.

Renewables and the Russian economy

As nations begin to move towards clean energy, fossil fuel exporting countries will need to rethink and reshape their economies. Taking Russia as an example, an MIT study has examined the likely impact on oil, gas and coal exports and the opportunities the energy transition could offer.

There’s something fishy about this flow battery innovation

Scientists led by MIT have suggested chitin, a carbon and nitrogen-rich material made from waste shrimp shells, could produce sustainable electrodes for vanadium redox flow batteries and other energy storage technologies.

Used EV batteries for large scale solar energy storage

MIT scientists have suggested used electric vehicle batteries could offer a more viable business case than purpose-built systems for the storage of grid scale solar power in California. Such ‘second life’ EV batteries, may cost only 60% of their original purchase price to deploy and can be effectively aggregated for industrial scale storage even if they have declined to 80% of their original capacity.

Quebec as a big battery for the northeastern US

Researchers at MIT say the immense hydropower resources of the Canadian province could be used as storage to even out the supply of intermittent renewables generation in New England and New York state.

What’s cooking in Eni’s PV lab?

Researchers at the Italian oil group are trying to improve organic photovoltaics and luminescent solar concentrators and a new supercomputer with sophisticated algorithms will help them with the solar energy puzzle.

The path to market for perovskites

MIT scientists have taken a deep dive into solar technology markets in search of an economically sustainable path to commercialization for perovskites. The group estimates $1 billion of capital expenditure would be required to achieve the economies of scale necessary to compete with rival solar module technologies. However, several alternative suggestions for scaling up with lower investment costs were also considered.

Recycling heat for a ‘385% efficient’ solar desalinator

MIT scientists have developed a solar desalinator which transports heat from the sun through a ten-stage process of evaporation and condensation. The group estimates a $100 device employing their innovation could provide the daily drinking water needs of a family.

MIT researchers say PV innovations should be deployed in niche markets first

Solar module manufacturers should begin testing new technologies in higher-value niche markets, say scientists at the U.S. institution. For example, bringing perovskite technology directly to the mainstream market remains prohibitive in terms of initial investment but segments such as building-integrated PV or microelectronics devices may offer better routes to commercial maturity.

Innovative PV modules at Intersolar San Diego

In sunny San Diego for Intersolar 2020, we’re seeing a new idea for tracking rooftop solar modules, diodes moving to cell level, two types of building-integrated solar products and some solar hot water.
