California Awards $3.5 Million for Microgrid at Frito-Lay Food Processing Plant

on November 13, 2020

The California Energy Commission has awarded Frito-Lay a $3.5 million grant to build a solar-powered microgrid at a food processing facility in a project the agency is touting as a model for the industry.

The microgrid will be installed at a snack food processing facility in Rancho-Cucamonga, California, to reduce greenhouse gas emissions and to allow the plant to keep running during power outages.

SunPower will provide the project’s solar equipment and microgrid controller while Tesla will supply the project’s energy storage component, according to the CEC, which approved the grant Nov. 10.

The solar panels are expected to produce about 3,500 MWh a year, reducing greenhouse gas emissions by about 850 metric tons annually. The battery system will be able to supply the plant’s critical load for up to six hours before needing to be recharged.

CEC sees microgrid as industry model
“By implementing a microgrid at a food processor, this project will demonstrate the benefits of renewable energy production and electricity reliability to other industrial customers, as well as the benefits of microgrid technology more broadly to utilities and other involved parties,” Kevin Uy, a CEC staff in the agency’s energy research and development division, said in a memo supporting the grant.

Microgrids can help food production facilities deal with planned and unplanned power outages, which can lead to significant financial and product losses, Uy said during the meeting when the commission unanimously approved the grant.

Also, solar microgrids provide a renewable alternative to backup diesel generators, according to Uy.

The battery storage component provides customers with cost savings and resiliency while supporting the grid through strategic charging and discharging, Uy said.

Automated Bidding is The Next Step in The Evolution of Energy Storage

on November 13, 2020
Utility-Dive

While 2020 has obviously been challenging on many fronts, one of the surprising upsides we have seen in the power industry is that the vision of a very high renewable energy penetration grid is not only technically feasible, but it might arrive faster than anyone anticipated. I wrote in Utility Dive this past August, detailing the experience of electricity markets in Europe during the pandemic, which was characterized by large shares of renewable energy on the grid and the shutdown of much of the continent’s baseload generation capacity.

A key component of this transition is the deployment of flexible generation – primarily grid-scale batteries – that allow for the optimization of these renewable resources. At Wärtsilä, our focus has been not only the deployment of these flexible storage assets but most importantly their optimization through asset-level and portfolio control.

This strategy has led to many interesting conversations with our customers, allowing us to collaboratively find new ways to increase the value of energy storage assets. One of the most exciting, and the key to the growth of energy storage as a market category, is the ability to leverage artificial intelligence for automated bidding of stored renewable power into competitive electricity markets.

This has the potential to be a game-changer for energy storage, mitigating the risk from merchant revenue streams atop the already clear benefits provided by grid-scale batteries.

The market is taking notice. In my conversations with IPPs, I am increasingly hearing that operators are rethinking their trading strategies to incorporate storage and take advantage of these potentially lucrative arbitrage opportunities. These customers typically fall into two categories.

Energy for the People: Microgrids and the Democratization of Energy

on November 13, 2020

The US has made significant efforts towards modernizing its electrical grid, yet the existing disparity in power quality and electricity savings achieved among communities and individual consumers demonstrates we still have ways to go. When microgrids were first introduced, they offered a viable technology solution to help consumers upgrade their energy infrastructure. With their ability to integrate cleaner resources into our power mix, mitigate costs and increase reliability, microgrids transformed the way we consumed our electricity.

Although microgrids have been around for quite some time, it wasn’t until recent years that we saw adoption quickly spread among municipalities, large commercial buildings, campuses and critical facilities. As we experienced first-hand the resilience and sustainability benefits microgrids offer, especially in the face of severe weather and prolonged blackouts, the more cities and businesses considered the technology as part of their energy infrastructure strategy.

Fast forward to today, technological advancements and the maturation of innovative business models, such as Energy-as-a-Service (EaaS), have further enabled the growth of microgrids. As a model that presented a way to invest in microgrids with little to no upfront capital expense and minimal risk, EaaS was the solution for addressing the biggest financial barrier to deployment and a key driver to the uptick in microgrid adoption.

Microgrids are a viable solution for all organizations seeking to gain control over their energy costs, advance sustainability, and increase resilience, and it’s up to the industry as a whole to help make them accessible to everyone.

Still, the primary customer for microgrids widely remains municipal, district, institutional, commercial campus and large buildings. While we’ve experienced many technological breakthroughs in the last decade to reach more advanced and smarter microgrids, it’ll be the ongoing economic breakthroughs that will enable us to reach mass adoption and transform the power grid as we know it.

Holy Grail of Energy Storage Technology Receives Two Grants

on November 12, 2020

RheEnergise is one of only a select handful of businesses to have been awarded grants under both the Sustainable Innovation Fund & the Small Business Research Initiative.

RheEnergise is bringing innovation to pumped energy storage and developing a technology that solves the many disadvantages of other competing energy storage and grid flexibility solutions. The awarded grants are supporting a feasibility study into a £1.6m demonstration project with full system functionality specifically designed for use with the RheEnergise high-technology fluid taking the extensive theoretical and practical learning to the next level. For further information see the IDTechEx report on Potential Stationary Energy Storage Technologies to Monitor.

The UK’s Climate Change Committee states that energy storage is the key enabler necessary to achieve a net-zero carbon energy system however there is nowhere near enough energy storage for a zero-carbon energy system that includes transport, power and heat. Unlike traditional pumped hydro energy storage, RheEnergise’s HD Hydro operates on small hills rather than mountains meaning there are infinitely more sites available for projects.

The Business Secretary Alok Sharma said: “The UK’s response to coronavirus has demonstrated the very best of British ingenuity, and it is this resourcefulness that will help us navigate our way through this pandemic. Today’s investment will ensure that our innovators and risk-takers can continue to scale up their ideas, helping the UK to build back better and ensure we meet our clear commitments on tackling climate change.”

Innovate UK Executive Chair Dr Ian Campbell said: “In these difficult times we have seen the best of British business innovation. The pandemic is not just a health emergency but one that impacts society and the economy. RheEnergise’s energy storage innovations, along with every initiative Innovate UK has supported through this fund, is an important step forward in driving sustainable economic development.”

Stephen Crosher, RheEnergise’s CEO said: ‘Society needs energy storage to match the intermittent supply of renewables with the variable demand by consumers. These awards by Innovate UK will make a significant difference to RheEnergise, to accelerate the time it takes to bring our High-Density Hydro innovations to market and our goal of developing the lowest cost energy storage solution available.’

Flow Battery to Be Paired with Solar at South African Vanadium Mine’s Microgrid System

on November 12, 2020
Energy-Storage-News

A solar-plus-storage microgrid being deployed at an alloys mine in South Africa will feature a vanadium flow battery energy storage system, using locally sourced vanadium electrolyte.

The micro, or mini-grid, will serve close to 10% of total electrical consumption required at the Vametco Alloys integrating vanadium mining and processing plant in the North West Province of South Africa.

Pairing 3.5MW of solar PV generation with the 1MW / 4MWh vanadium redox flow battery (VRFB) storage unit, the project will also serve to demonstrate the capabilities and benefits of VRFBs, according to Bushveld Minerals, the company behind the project.

Bushveld owns the Vametco mine and has appointed European infrastructure solutions company Abengoa as engineering, procurement and construction (EPC) partner on the project, with Abengoa also providing its proprietary energy management system technology to operate the microgrid.

Abengoa said it has already commissioned 250MW of power generation projects with energy storage in Africa over the past 10 years, as well as being its fourth such project in South Africa. The Vametco project is, however, the first-ever commercial-scale hybrid project on the African continent to use VRFB technology, Abengoa said. Abengoa will install the Vametco Alloys project’s solar PV as well as integrating the system and providing maintenance after commissioning.

The vanadium flow battery provider to the project will be Enerox, which Bushveld also owns. Enerox produces systems under the brand name CellCube. Enerox CEO Alexander Schoenfeldt said that he expected the hybrid installation to “become a blueprint for many more to come”.

Vametco will provide 25 tonnes of vanadium oxide to be converted for use as electrolyte in the battery system. Bushveld said that the use of “locally mined and beneficiated vanadium” shows how “VRFB energy solutions can create more local value to South Africa than any other storage technology”.

UK Warning Highlights Energy Storage Importance To Renewables

on November 9, 2020
oilprice-logo

The United Kingdom, which has recently set a record for wind power meeting its demand, issued a security of supply alert earlier this week as wind power output was low due to calm weather. This event highlights the need of increased energy storage capacity able to balance power to the grid at times of strained supply, energy historian and expert Ellen R. Wald wrote in Forbes.

On Tuesday, National Grid ESO issued an electricity margin notice (EMN) for the evening on Wednesday. “This is a routine signal that we send to the market to indicate that we’d like a larger cushion of spare capacity,” National Grid said. The grid operator was expecting tight margins on the UK electricity system because of low renewable output and the availability of generators over periods of the day with higher demand.

“The tight margins on the electricity system are the result of a number of factors including the weather, demand for electricity and the availability of generators,” National Grid said on Wednesday.

The UK alert about tight margins of spare supply poses again the question of how grids will accommodate growing shares of wind and solar power generation while ensuring there will be no blackouts.

The UK wants to significantly boost its wind power generation, which already holds a high share in the power mix, to the point of powering every home with wind by 2030.

The UK will aim to become a global leader in offshore wind energy, powering every home in the country with wind by 2030, Prime Minister Boris Johnson said in early October.

Currently, offshore wind meets 10 percent of the UK electricity demand. 

Last year, the UK became the first major economy in the world to enshrine into law its target to reduce its greenhouse gas emissions to net zero by 2050.

Germany’s New Draft Renewable Energy Laws Are ‘A Slap in The Face For Prosumers’

on November 9, 2020
Energy-Storage-News

Germany’s draft renewable energy laws, which the government is seeking to introduce next year, have been heavily criticised by energy storage systems association BVES.

A critical piece of the country’s energy transition (Energiewende) legislature, which originally aims to bring about an economically feasible low carbon society, the German Renewable Energy Sources Act (‘Erneuerbare-Energien-Gesetz’ – EEG) first introduced a feed-in tariff for renewable energy in the year 2000.

With the 20-year remuneration period for those feed-in tariffs set to expire, the Ministry of Economic Affairs and Energy introduced a new EEG in mid-September. The new laws should also enable Germany to comply with European Union policies such as the EU Clean Energy Package as well as the country’s obligations under the Paris Agreement on climate protection.

Valeska Gottke, head of communications and markets for the energy storage systems association BVES, told Energy-Storage.news in an interview that the draft law as it stands, is “bad news for the successful continuation of the Energiewende as it does not bring renewable ‘power to the people'”.

“In their analyses of the Market Design Directive and the Renewable Energy Directive II, our BVES legal experts came to the conclusion that the current draft of the EEG does not implement EU law and, if the current draft of the EEG remains unchanged, Germany can be accused of violating EU treaties,” Gottke said.

“The EU Clean Energy Package emphasises strengthening the role in the electricity system of the prosumer – citizens or businesses that generate and consume their own onsite renewable energy, to which battery storage is considered key.”

Yet the new draft law does not even mention the EU Market Design Directive around protecting or supporting prosumers. The home energy storage market, which has been booming in Germany in the past couple of years “has already shown how essential it is for the goals of the Energiewende and may now be forced to fall short of its potential,” Gottke said.

The Batteries of the Future Are Weightless and Invisible

on November 9, 2020

ELON MUSK MADE a lot of promises during Tesla’s Battery Day last September. Soon, he said, the company would have a car that runs on batteries with pure silicon anodes to boost their performance and reduced cobalt in the cathodes to lower their price. Its battery pack will be integrated into the chassis so that it provides mechanical support in addition to energy, a design that Musk claimed will reduce the car’s weight by 10 percent and improve its mileage by even more. He hailed Tesla’s structural battery as a “revolution” in engineering—but for some battery researchers, Musk’s future looked a lot like the past.

“He’s essentially doing something that we did 10 years ago,” says Emile Greenhalgh, a materials scientist at Imperial College London and the Royal Academy of Engineering Chair in Emerging Technologies. He’s one of the world’s leading experts on structural batteries, an approach to energy storage that erases the boundary between the battery and the object it powers. “What we’re doing is going beyond what Elon Musk has been talking about,” Greenhalgh says. “There are no embedded batteries. The material itself is the energy storage device.”

Today, batteries account for a substantial portion of the size and weight of most electronics. A smartphone is mostly a lithium-ion cell with some processors stuffed around it. Drones are limited in size by the batteries they can carry. And about a third of the weight of an electric vehicle is its battery pack. One way to address this issue is by building conventional batteries into the structure of the car itself, as Tesla plans to do. Rather than using the floor of the car to support the battery pack, the battery pack becomes the floor.

But for Greenhalgh and his collaborators, the more promising approach is to scrap the battery pack and use the vehicle’s body for energy storage instead. Unlike a conventional battery pack embedded in the chassis, these structural batteries are invisible. The electrical storage happens in the thin layers of composite materials that make up the car’s frame. In a sense, they’re weightless because the car is the battery. “It’s making the material do two things simultaneously,” says Greenhalgh. This new way of thinking about EV design can provide huge performance gains and improve safety because there won’t be thousands of energy-dense, flammable cells packed into the car.

Solar Power Could Provide Energy For The World’s Most Vulnerable. Here Are 5 Ways To Pay For It

on November 6, 2020

It’s hard to overstate the challenges facing the 600 million people in Africa who lack access to electricity—including over 20 million who have been forcibly displaced. Without light sources, for instance, schoolwork is limited to daylight hours, hampering educational achievement. When small home businesses cannot operate after dark, it drastically curtails their income potential.

For displaced people, these limitations come on top of a variety of other hardships, from property loss to physical violence and persecution. In short, access to energy is a vital economic lifeline. And based on our research, it could be provided—both sustainably and cheaply—through solar power.

Africa’s energy challenge

In many Sub-Saharan African countries, the majority of citizens lack access to electricity. These same countries also host sizeable displaced populations, making it tough to start working towards achieving Goal 7 (access to affordable, reliable, sustainable, and modern energy for all by 2030) of the United Nations’ Sustainable Development Goals (SDGs). Moreover, SDGs in other areas such as education, increased income, health care, innovation, and economic growth also depend on access to energy.

The arguments for scaling up access to solar power are compelling. First, solar is increasingly affordable (costs have fallen five times in the past decade) and more viable for poor communities than the current alternative: unhealthy and polluting diesel generators, which are expensive to operate and add to carbon emissions.

In BCG’s collaboration with NORCAP, a global provider of expertise to the humanitarian, development, and peace-building sectors, we identified a suite of solar solutions that can work for vulnerable and displaced communities. These range from replacing fossil-based generators with solar power to enhancing mini-grid systems in displaced and host communities for households, services, and industry.
