Distributed Storage

Dutch transmission system operator Tennet, which also serves Germany, is planning to create flexible electricity demand and reduce grid congestion by promoting the use of smarter heating systems and heat pumps that can also be powered by solar and wind energy. According to its experts, intelligent control of heat pumps may result in the creation of between 0.5 and 1 GW of temporary grid flexibility by 2030.

In an earnings call this week, Tesla CEO Elon Musk boldly claimed that the company will soon be “the market leader in solar.”

A new Wood Mackenzie report suggests that costs for front-of-the-meter battery storage systems in the Asia-Pacific region could fall by 30% by 2025. The declining costs are already having a palpable impact, as 2021 has opened with a slew of large-scale battery project announcements.

The private-sector arm of the World Bank, which claims to leverage $3 of its own capital and $8 from third parties for every dollar invested in its blended finance funds, has attempted to quantify what devoting Covid recovery funds to green investment would mean for emerging economies.

A report by McKinsey & Company reinforces the widely-held view renewables will supplant fossil fuels in the energy system but also joins the chorus of voices warning the world is on track to fall well short of limiting global temperature rises this century to 1.5C.

Scientists in Japan demonstrated a hard-carbon electrode that can greatly increase the capacity of a sodium-ion battery. With further work on the long-term performance, the discovery could make sodium-ion batteries better able to compete on energy density with their lithium-ion counterparts.

Researchers in Finland have demonstrated the technical feasibility of an off-grid residential PV system combined with short-term battery storage and seasonal hydrogen storage. The proposed model is applicable only to northern climates, as higher levels of solar radiation in southern locations would mean a reduced need for seasonal storage. It was tested in an existing single-family house in Finland with a 21 kW rooftop array and a ground source 6 kW heat pump.

The floating restaurants and boats shall have on-board Li-ion battery storage to continuously power main motors and utility loads for six hours on a single charge. The batteries shall be charged by solar power and AC current from the shore to ensure the loads’ uninterrupted operation.

The selected applicants are required to execute projects across categories like solar-powered cold storage, solar water pumps, solar-powered reverse-osmosis water systems and off-grid solar systems for primary health care centers on a turnkey basis. The work includes engineering, supply, erection, commissioning along with maintenance support for three years.

TP Renewable Microgrid has installed an aggregate 3 MW of solar microgrid capacity with its 100th project commissioned in Ratnapur, Uttar Pradesh.
