Power company to test flow battery’s ability to manage grid services

Thu, 11/11/2021 - 11:02 -- Paul Crompton

US technology conglomerate Honeywell’s flow battery will be tested by Duke Energy to determine its capabilities of storing renewable generated power.

The long-duration 400kWh flow battery unit will store power from wind and solar generation for use during power outages or when the grid is at capacity. 

The system, which can store and discharge electricity for up to 12 hours, is designed with recyclable components and could provide a reliable and cost-efficient system for 20 years, say North Carolina-based Honeywell.

The flow battery technology will be tested at power company Duke Energy’s Emerging Technology and Innovation Center in Mount Holly, North Carolina.

Honeywell will deliver the unit to Duke’s facility next year.

Honeywell aims to deploy a utility-scale pilot project of 60MWh starting in 2023.

Ben Owens, vice president and general manager, Honeywell Sustainable Technology Solutions, said: “As utilities and corporations seek cost-effective alternatives to coal-fired plants with long-duration energy storage solutions, they are switching to renewable energy targets that work around the clock to reduce carbon emissions. 

“By partnering with Duke, we can implement this innovative energy storage technology at scale and bring to market a revolutionary flow battery to meet growing energy storage demands, while assisting companies in meeting their carbon neutral goals.”

Over the next five years, Duke Energy plans to install almost 400MW of battery storage capacity in its service territory and is interested in so-called breakthrough technologies.

Renewable adoption to drive stationary lead-acid battery market growth

Tue, 08/24/2021 - 13:31 -- Paul Crompton

The global stationary market for lead-acid batteries is estimated to reach $11 billion by 2030, according to a new report by industry analysts Frost and Sullivan.

The rise will represent a $2.7 billion uptick at a compound annual growth rate of 4.1% from the start of the decade.

The report ‘Global Stationary Lead Acid Battery Growth Opportunities’ noted the technology’s low price, ease of recyclability, and user-friendliness were expediting their adoption across telecom and data centers, automobiles, oil and gas, and utilities industries. 

The analysts also suggest the demand for renewable energy power—mainly solar and wind— will increase the adoption of stationary lead-acid batteries for backup power, and peak-load shifting services.

Manoj Shankar, energy and environment research analyst at Frost & Sullivan, said: “The implementation of stringent norms by governments worldwide to lower their carbon footprint as part of their commitment toward climate change will further accelerate the uptake of backup and storage systems.

"Several countries in Asia and Africa still lack access to the grid. Power demand exceeds supply, leading to power outages. 

“This power deficit will trigger the demand for stationary lead-acid batteries to power diesel gensets and UPS systems and store backup power. 

“Further, from a regional perspective, Asia-Pacific will be the largest market for stationary lead-acid batteries— due to increased investments in power generation, industrial developments and the growth of microgrid networks— followed by North America and Europe."

According to Frost and Sullivan, countries' commitments toward climate change and the increase in renewable energy penetration worldwide present lucrative growth prospects for stationary lead-acid batteries market participants, including:

  • Consolidation and geographic expansion: Market participants should expand their manufacturing footprint in the developed world because establishing local bases is crucial to serving local customers. 
  • New product development: Companies must invest in developing battery monitoring platforms that can be integrated with UPS systems and diesel monitoring systems to achieve higher battery efficiency. 
  • Solar photovoltaic (PV) deployment: Manufacturers should shift to utility and grid storage deployment as power demand is expected to peak in these sectors by 2030.
