Walmart and Tesla are going to try and work things out – gpgmail


Walmart came out swinging earlier this week in a lawsuit that accused Tesla of breach of contract and gross negligence over problems with rooftop solar panel systems installed at the retail giant’s stores.

Now, just days later, the lawsuit has been placed on hold while the two companies try to reach an agreement that would keep the solar installations in place and put them back in service, according to a joint statement issued late Thursday night.

“Walmart and Tesla look forward to addressing all issues and re-energizing Tesla solar installations at Walmart stores, once all parties are certain that all concerns have been addressed,” the statement read. “Together, we look forward to pursuing our mutual goal of a sustainable energy future. Above all else, both companies want each and every system to operate reliably, efficiently, and safely.”

Walmart hasn’t dropped the lawsuit. The complaint is still on file with New York state court. But the two parties are going to try and reach an agreement that would avoid a lawsuit.

The lawsuit, which is aimed at Tesla’s energy unit that was formerly known as SolarCity, alleges that seven fires on Walmart rooftops were caused by the solar panel systems. Walmart asked Tesla to remove the solar panel systems on all 244 stores where they are currently installed and to pay for damages related to fires that the retailer alleges stem from the panels.

Now, a Walmart spokesperson said it is “actively working towards a resolution” with Tesla.

Neither Tesla or Walmart would explain the details of the negotiations.

The stakes are high for Tesla. Earlier this month, Tesla CEO Elon Musk  announced a new rental offering for solar power in a bid to reboot the flagging renewable energy business.

Tesla’s share of the solar market has declined since its merger with SolarCity in 2016. In the second quarter Tesla deployed only 29 megawatts of new solar installations, while the number one and two providers of consumer solar, SunRun and Vivint Solar, installed 103 megawatts and 56 megawatts, respectively.

Tesla’s renewable energy business includes residential and commercial solar and energy storage products. The company also has a utility-scale energy product called Megapack. While Tesla still produces solar panels for residential use, much of its focus has been on developing its solar roof, which is comprised of tiles. It still operates a commercial business, which targets municipalities, schools, affordable housing, enterprise and agriculture and water districts as customers.

The company doesn’t provide a breakdown of its solar installations, making it difficult to determine if the commercial business is flat, falling or on the rise. Language in its latest 10-Q suggests Tesla is putting a renewed effort into its solar business.

Tesla said it’s working on revamping the customer service experience for solar products, according to the 10-Q. The company said while its retrofit solar system deployments have it expects they “will stabilize and grow in the second half of the year.”

Frontier technologies are moving closer to the center of venture investment – gpgmail


As the technologies that were once considered science fiction become the purview of science, the venture capital firms that were once investing at the industry’s fringes are now finding themselves at the heart of the technology industry.

Investing in the commercialization of technologies like genetic engineering, quantum computing, digital avatars, augmented reality, new human-computer interfaces, machine learning, autonomous vehicles, robots, and space travel that were once considered “frontier” investments are now front-and-center priorities for many venture capital firms and the limited partners that back them.

Earlier this month, Lux Capital raised $1.1 billion across two funds that invest in just these kinds of companies. “[Limited partners] are now more interested in frontier tech than ever before,” said Bilal Zuberi, a partner with the firm.

He sees a few factors encouraging limited partners (the investors who provide financing for venture capital funds) to invest in the firms that are financing companies developing technologies that were once considered outside of the mainstream.

Y Combinator-backed Holy Grail is using machine learning to build better batteries – gpgmail


For a long, long time, renewable energy proponents have considered advancements in battery technology to be the holy grail of the industry.

Advancements in energy storage has been among the hardest to achieve economically thanks to the incredibly tricky chemistry that’s involved in storing power.

Now, one company that’s launching from Y Combinator believes it has found the key to making batteries better. The company is called Holy Grail and it’s launching in the accelerator’s latest cohort.

With an executive team that initially included Nuno Pereira, David Pervan, and Martin Hansen, Holy Grail is trying to bring the techniques of the fabless semiconductor industry to the world of batteries.

The company’s founders believe that the only way to improve battery functionality is to take a systems approach to understanding how different anodes and cathodes will work together. It sounds simple, but Pereira says that the computational power hadn’t existed to take into account all of the variables that go along with introducing a new chemical to the battery mix.

“You can’t fix a battery with just a component,” Pereira says. “All of the batteries that were created and failed in the past. They create an anode, but they don’t have a chemical that works with the cathode or the electrolyte.”

For Pereira, the creation of Holy Grail is the latest step on a long road of experimentation with mechanical and chemical engineering. “As a kid I was more interested in mechanical engineering and building stuff,” he says. But as he began tinkering with cars and became fascinated with mobility, he realized that batteries were the innovation that gave the world its charge.

In 2017 Pereira founded a company called 10Xbattery, which was making high-density lithium batteries. That company, launching with what Pereira saw as a better chemistry, encapsulated the industry’s problem at large — the lack

So, with the help of a now-departed co-founder, Pereira founded Holy Grail. “He essentially told me, ‘Do you want to take a step back and see if there’s a better way to do this?’” said Pereira.

The company pitches itself as science fiction coming from the future, but it relies on a combination of what are now fairly standard (at least in the research community) tools. Holy Grail’s pitch is that it can automate much of the research and development process to create new batteries that are optimized to the specifications of end customers.

“It’s hard for a human to do the experiments that you need and to analyze multidimensional data,” says Pereira. “There are some companies that only do the machine-learning part and the computational science part and sell the results to companies. The problem is that there’s a disconnection between experimental reality and the simulations.”

Using computer modeling, chemical engineering and automated manufacturing, Holy Grail pitches a system that can get real test batteries into the hands of end customers in the mobility, electronics, and utility industries orders of magnitude more quickly than traditional research and development shops.

Currently the system that Holy Grail has built out can make 700 batteries per day. The company intends to  build a pilot plant that will make batteries for electronics and drones. For automotive and energy companies, Holy Grail says it will partner with existing battery manufacturers that can support the kind of high-throughput manufacturing big orders will require.

Think of it like bringing the fabless chip design technologies and business models to the battery industry, says Pereira.

Holy Grail already has $14 million in letters of intent with potential customers, according to Pereira and is expecting to close additional financing as it exits Y Combinator.

To date the company has been backed by the London-based early stage investment firm Deep Science Ventures, where Pereira worked as an entrepreneur in residence.

Ultimately, the company sees its technology being applied far beyond batteries as a new platform for materials science discoveries broadly. For now, though the focus is on batteries.

“For the low volume we sell direct,” says Pereira. “While on high volume production, we will implement a pilot line through the system… we are able to do the research engineering with the small ones and test the big ones. In our case when we have a cell that works, it’s not something that works in a lab it’s something that works in the final cell.”

Energy Vault raises $110 million from SoftBank Vision Fund as energy storage grabs headlines – gpgmail


Imagine a moving tower made of huge cement bricks weighing 35 metric tons. The movement of these massive blocks is powered by wind or solar power plants and is a way to store the energy those plants generate. Software controls the movement of the blocks automatically, responding to changes in power availability across an electric grid to charge and discharge the power that’s being generated.

The development of this technology is the culmination of years of work at Idealab, the Pasadena, Calif.-based startup incubator, and Energy Vault, the company it spun out to commercialize the technology, has just raised $110 million from SoftBank Vision Fund to take its next steps in the world.

Energy storage remains one of the largest obstacles to the large-scale rollout of renewable energy technologies on utility grids, but utilities, development agencies and private companies are investing billions to bring new energy storage capabilities to market as the technology to store energy improves.

The investment in Energy Vault is just one indicator of the massive market that investors see coming as power companies spend billions on renewables and storage. As The Wall Street Journal reported over the weekend, ScottishPower, the U.K.-based utility, is committing to spending $7.2 billion on renewable energy, grid upgrades and storage technologies between 2018 and 2022.

Meanwhile, out in the wilds of Utah, the American subsidiary of Japan’s Mitsubishi Hitachi Power Systems is working on a joint venture that would create the world’s largest clean energy storage facility. That 1 gigawatt storage would go a long way toward providing renewable power to the Western U.S. power grid and is going to be based on compressed air energy storage, large flow batteries, solid oxide fuel cells and renewable hydrogen storage.

“For 20 years, we’ve been reducing carbon emissions of the U.S. power grid using natural gas in combination with renewable power to replace retiring coal-fired power generation. In California and other states in the western United States, which will soon have retired all of their coal-fired power generation, we need the next step in decarbonization. Mixing natural gas and storage, and eventually using 100% renewable storage, is that next step,” said Paul Browning, president and CEO of MHPS Americas.

Energy Vault’s technology could also be used in these kinds of remote locations, according to chief executive Robert Piconi.

Energy Vault’s storage technology certainly isn’t going to be ubiquitous in highly populated areas, but the company’s towers of blocks can work well in remote locations and have a lower cost than chemical storage options, Piconi said.

“What you’re seeing there on some of the battery side is the need in the market for a mobile solution that isn’t tied to topography,” Piconi said. “We obviously aren’t putting these systems in urban areas or the middle of cities.”

For areas that need larger-scale storage that’s a bit more flexible there are storage solutions like Tesla’s new Megapack.

The Megapack comes fully assembled — including battery modules, bi-directional inverters, a thermal management system, an AC breaker and controls — and can store up to 3 megawatt-hours of energy with a 1.5 megawatt inverter capacity.

The Energy Vault storage system is made for much, much larger storage capacity. Each tower can store between 20 and 80 megawatt hours at a cost of 6 cents per kilowatt hour (on a levelized cost basis), according to Piconi.

The first facility that Energy Vault is developing is a 35 megawatt-hour system in Northern Italy, and there are other undisclosed contracts with an undisclosed number of customers on four continents, according to the company.

One place where Piconi sees particular applicability for Energy Vault’s technology is around desalination plants in places like sub-Saharan Africa or desert areas.

Backing Energy Vault’s new storage technology are a clutch of investors, including Neotribe Ventures, Cemex Ventures, Idealab and SoftBank.

Tesla has a new energy product called Megapack – gpgmail


Tesla has launched a new utility-scale energy storage product called Megapack modeled after the giant battery system it deployed in South Australia as the company seeks to provide an alternative to natural gas “peaker” power plants.

Megapack is the third and largest energy storage system offered by Tesla. The company also sells the residential Powerwall and the commercial Powerpack systems.

Megapack, which Tesla announced Monday in a blog post, is the latest effort by the company to retool and grow its energy storage business, which is a smaller revenue driver than sales of its electric vehicles. Of the $6.4 billion in total revenue posted in the second quarter, just $368 million was from Tesla’s solar and energy storage product business.

Tesla did deploy a record 415 megawatt-hours of energy storage products in the second quarter, a 81% increase from the previous quarter, according to Tesla’s second quarter earnings report that was released July 24. Powerwalls are now installed at more than 50,000 sites.

The Megapack offering could provide an even bigger boost if Tesla can convince utilities to opt for it instead of the more common natural gas peaker plants used today. And it seems it already has.

Tesla’s Megapack will provide 182.5 MW of the upcoming 567 MW Moss Landing energy storage project in California with PG&E.

The so-called Megapack was specifically designed and engineered to be an easy-to-install utility-scale system. Each system comes fully assembled — that includes battery modules, bi-directional inverters, a thermal management system, an AC main breaker and controls —with up to 3 megawatt-hours of energy storage and 1.5 MW of inverter capacity.

The system includes software, developed by Tesla, to monitor, control and monetize the  installations, the company said in a blog post announcing Megapack.

All Megapacks connect to Powerhub, an advanced monitoring and control platform for large-scale utility projects and microgrids, and can also integrate with Autobidder, Tesla’s machine-learning platform for automated energy trading, the company said.

Megapack was inspired by Tesla’s Hornsdale project, which combined its 100 MW Powerpack system with Neoen’s wind farm near Jamestown in South Australia. The Tesla Powerpack system stored power generated by the wind farm and then delivered the electricity to the grid during peak hours. The facility saved nearly $40 million in its first year.

Today, the go-to option for utilities are natural gas “peaker” power plants. Peaker power plants are used when a local utility grid can’t provide enough power to meet peak demand, an occurrence that has become more common as temperatures and populations rise.

Tesla hopes to be the sustainable alternative. And in states like California, which have ambitious emissions targets, Tesla could gain some ground. Instead of using a natural gas peaker plant, utilities could use the Megapack to store excess solar or wind energy to support the grid’s peak loads.
