Geothermal technology has enormous potential to power the planet and Fervo wants to tap it
Tapping the geothermal energy stored beneath the Earth’s surface as a way to generate renewable power is one of the new visions for the future that’s captured the attention of environmentalists and oil and gas engineers alike.
That’s because it’s not only a way to generate power that doesn’t rely on greenhouse gas emitting hydrocarbons, but because it uses the same skillsets and expertise that the oil and gas industry has been honing and refining for years.
At least that’s what drew the former completion engineer (it’s not what it sounds like) Tim Latimer to the industry and to launch Fervo Energy, the Houston-based geothermal tech developer that’s picked up funding from none other than Bill Gates’ Breakthrough Energy Ventures (that fund… is so busy) and former eBay executive, Jeff Skoll’s Capricorn Investment Group.
With the new $28 million cash in hand, Fervo’s planning on ramping up its projects, which Latimer said would “bring on hundreds of megawatts of power in the next few years.”
Latimer got his first exposure to the environmental impact of power generation as a kid growing up in a small town outside of Waco, Texas near the Sandy Creek coal power plant, one of the last coal-powered plants to be built in the U.S.
Like many Texas kids, Latimer came from an oil family, and got his first jobs in the oil and gas industry before realizing that the world was going to be switching to renewables and the oil industry — along with the friends and family he knew — could be left high and dry.
It’s one reason he started working on Fervo, the entrepreneur said.
“What’s most important, from my perspective, since I started my career in the oil and gas industry, is providing folks that are part of the energy transition on the fossil fuel side to work in the clean energy future,” Latimer said. “I’ve been able to go in and hire contractors and support folks that have been out of work or challenged because of the oil price crash… And I put them to work on our rigs.”

When the Biden administration talks about finding jobs for employees in the hydrocarbon industry as part of the energy transition, this is exactly what they’re talking about.
And geothermal power is no longer as constrained by geography, so there are a lot of abundant resources to tap and the potential for high-paying jobs in areas that are already dependent on geological services work, Latimer said (late last year, Vox published a good overview of the history and opportunity presented by the technology).
“A large percentage of the world’s population actually lives next to good geothermal resources,” Latimer said. “[There are] 25 countries today that have geothermal installed and producing and another 25 where geothermal is going to grow.”
Geothermal power production actually has a long history in the Western U.S. and in parts of Africa where naturally occurring geysers and steam jets pouring from the earth have been obvious indicators of good geothermal resources, Latimer said.
“Fervo’s technology unlocks a new class of geothermal resource that is ready for large-scale deployment. Fervo’s geothermal systems use novel techniques, including horizontal drilling, distributed fiber optic sensing and advanced computational modelling, to deliver more repeatable and cost effective geothermal electricity,” Latimer wrote in an email. “Fervo’s technology combines with the latest advancements in Organic Rankine Cycle generation systems to deliver flexible, 24/7 carbon-free electricity.”
Initially developed with a grant from the TomKat Center at Stanford University and a fellowship funded by Activate.org at the Lawrence Berkeley National Lab’s Cyclotron Road division, Fervo has gone on to score funding from the DOE’s Geothermal Technology Office and ARPA-E to continue work with partners like Schlumberger, Rice University and the Berkeley Lab.
The combination of new and old technology is opening vast geographies to the company to potentially develop new projects.
Other companies are also looking to tap geothermal power to drive a renewable power-generation development business. Those are startups like Eavor, which has the backing of energy majors like bp Ventures, Chevron Technology Ventures, Temasek, BDC Capital, Eversource and Vickers Venture Partners; and other players including GreenFire Energy and Sage Geosystems.
Demand for geothermal projects is skyrocketing, opening up big markets for startups that can nail the cost issue for geothermal development. As Latimer noted, from 2016 to 2019 there was only one major geothermal contract, but in 2020 there were 10 new major power purchase agreements signed by the industry.
For all of these projects, cost remains a factor. Contracts that are being signed for geothermal that are in the $65 to $75 per megawatt range, according to Latimer. By comparison, solar plants are now coming in somewhere between $35 and $55 per megawatt, as The Verge reported last year.
But Latimer said the stability and predictability of geothermal power made the cost differential palatable for utilities and businesses that need the assurance of uninterruptible power supplies. As a current Houston resident, the issue is something that Latimer has an intimate experience with from this year’s winter freeze, which left him without power for five days.
Indeed, geothermal’s ability to provide always-on clean power makes it an incredibly attractive option. In a recent Department of Energy study, geothermal could meet as much as 16% of the U.S. electricity demand, and other estimates put geothermal’s contribution at nearly 20% of a fully decarbonized grid.
“We’ve long been believers in geothermal energy but have waited until we’ve seen the right technology and team to drive innovation in the sector,” said Ion Yadigaroglu of Capricorn Investment Group, in a statement. “Fervo’s technology capabilities and the partnerships they’ve created with leading research organizations make them the clear leader in the new wave of geothermal.”

Residential renewable energy developer Swell is raising $450 million for distributed power projects in three states
Swell Energy, an installer and manager of residential renewable energy, energy efficiency and storage technologies, is raising $450 million to finance the construction of four virtual power plants representing a massive amount of energy storage capacity paired with solar power generation.
It’s a sign of the distributed nature of renewable energy development and a transition from large-scale power generation projects feeding into utility grids at their edge to smaller, point solutions distributed at the actual points of consumption.
The project will pair 200 megawatt hours of distributed energy storage with 100 megawatts of solar photovoltaic capacity, the company said.
Los Angeles-based Swell was commissioned by utilities across three states to establish the dispatchable energy storage capacity, which will be made available through the construction and aggregation of approximately 14,000 solar energy generation and storage systems. The goal is to make local grids more efficient.
To finance these projects — and others the company expects to land — Swell has cut a deal with Ares Management Corp. and Aligned Climate Capital to create a virtual power plant financing vehicle with a target of $450 million.
That financing entity will support the development of power projects like the combined solar and battery agreement nationwide.
Over the next 20 years, Swell is targeting the development of over 3,000 gigawatt hours of clean solar energy production, with customers storing 1,000 gigawatt hours for later use, and dispatching 200 gigawatt hours of this stored energy back to the utility grid.
It has the potential to create a more resilient grid less susceptible to the kinds of power outages and rolling blackouts that have plagued states like California.
“Utilities are increasingly looking to distributed energy resources as valuable ‘grid edge’ assets,” said Suleman Khan, CEO of Swell Energy, in a statement. “By networking these individual homes and businesses into virtual power plants, Swell is able to bring down the cost of ownership for its customers and help utilities manage demand across their electric grids,” said Khan. “By receiving GridRevenue from Swell, customers participating in our VPP programs pay less for their solar energy generation and storage systems, while potentially reducing the risk of a local power outage, and keeping their homes and businesses securely powered through any outages.”
Along with the launch of the virtual power plant financing vehicle, Swell is also giving homeowners a way to finance their home energy systems through Swell. They need the buy-in from homeowners to get these power plants off the ground, and for homeowners, there’s a way to get some money back by feeding power into the grid.
It’s a win-win for the company, customers and early investors like Urban.us, which was seed investor in the company.

SunCulture wants to turn Africa into the world’s next bread basket, one solar water pump at a time
The world’s food supply must double by the year 2050 to meet the demands of a growing population, according to a report from the United Nations. And as pressure mounts to find new crop land to support the growth, the world’s eyes are increasingly turning to the African continent as the next potential global bread basket.
While Africa has 65% of the world’s remaining uncultivated arable land, according to the African Development Bank, the countries on the continent face significant obstacles as they look to boost the productivity of their agricultural industries.
On the continent, 80% of families depend on agriculture for their livelihoods, but only 4% use irrigation. Many families also lack access to reliable and affordable electricity. It’s these twin problems that Samir Ibrahim and his co-founder at SunCulture, Charlie Nichols, have spent the last eight years trying to solve.
Armed with a new financing model and purpose-built small solar-powered generators and water pumps, Nichols and Ibrahim have already built a network of customers using their equipment to increase incomes by anywhere from five to 10 times their previous levels by growing higher-value cash crops, cultivating more land and raising more livestock.
The company also just closed on $14 million in funding to expand its business across Africa.
“We have to double the amount of food we have to create by 2050, and if you look at where there are enough resources to grow food — all signs point to Africa. You have a lot of farmers and a lot of land, and a lot of resources,” Ibrahim said.
African small farmers face two big problems as they look to increase productivity, Ibrahim said. One is access to markets, which alone is a huge source of food waste, and the other is food security because of a lack of stable growing conditions exacerbated by climate change.
As one small farmer told The Economist earlier this year, “The rainy season is not predictable. When it is supposed to rain it doesn’t, then it all comes at once.”
Ibrahim, who graduated from New York University in 2011, had long been drawn to the African continent. His father was born in Tanzania and his mother grew up in Kenya and they eventually found their way to the U.S. But growing up, Ibrahim was told stories about East Africa.
While pursuing a business degree at NYU Ibrahim met Nichols, who had been working on large-scale solar projects in the U.S., at an event for budding entrepreneurs in New York.
The two began a friendship and discussed potential business opportunities stemming from a paper Nichols had read about renewable energy applications in the agriculture industry.
After winning second place in a business plan competition sponsored by NYU, the two men decided to prove that they should have won first. They booked tickets to Kenya and tried to launch a pilot program for their business selling solar-powered water pumps and generators.
Conceptually solar water-pumping systems have been around for decades. But as the costs of solar equipment and energy storage have declined, the systems that leverage those components have become more accessible to a broader swath of the global population.
That timing is part of what has enabled SunCulture to succeed where other companies have stumbled. “We moved here at a time when [solar] reached grid parity in a lot of markets. It was at a time when a lot of development financiers were funding the nexus between agriculture and energy,” said Ibrahim.
Initially, the company sold its integrated energy generation and water-pumping systems to the middle income farmers who hold jobs in cities like Nairobi and cultivate crops on land they own in rural areas. These “telephone farmers” were willing to spend the $5,000 required to install SunCulture’s initial systems.
Now, the cost of a system is somewhere between $500 and $1,000 and is more accessible for the 570 million farming households across the word — with the company’s “pay-as-you-grow” model.
It’s a spin on what’s become a popular business model for the distribution of solar systems of all types across Africa. Investors have poured nearly $1 billion into the development of off-grid solar energy and retail technology companies like M-kopa, Greenlight Planet, d.light design, ZOLA Electric and SolarHome, according to Ibrahim. In some ways, SunCulture just extends that model to agricultural applications.
“We have had to bundle services and financing. The reason this particularly works is because our customers are increasing their incomes four or five times,” said Ibrahim. “Most of the money has been going to consuming power. This is the first time there has been productive power.”
SunCulture’s hardware consists of 300-watt solar panels and a 440-watt-hour battery system. The batteries can support up to four lights, two phones and a plug-in submersible water pump.
The company’s best-selling product line can support irrigation for a two-and-a-half acre farm, Ibrahim said. “We see ourselves as an entry point for other types of appliances. We’re growing to be the largest solar company for Africa.”
With the $14 million in funding, from investors including Energy Access Ventures (EAV), Électricité de France (EDF), Acumen Capital Partners (ACP) and Dream Project Incubators (DPI), SunCulture will expand its footprint in Kenya, Ethiopia, Uganda, Zambia, Senegal, Togo and Cote D’Ivoire, the company said.
Ekta Partners acted as the financial advisor for the deal, while CrossBoundary provided additional advisory support, including an analysis on the market opportunity and competitive landscape, under the United States Agency for International Development (USAID)’s Kenya Investment Mechanism Program.

Sunrun’s $3.2 billion Vivint Solar bid challenges Tesla’s energy ambitions
Tesla’s 2014 acquisition of SolarCity turned the electric vehicle manufacturer into the undisputed largest player in residential solar, but that lead has steadily eroded as its major competitor, Sunrun, surged ahead with more aggressive plans. Now with the $3.2 billion acquisition of the residential solar installation company Vivint Solar, Sunrun looks to solidify its place in the top spot.
From Tesla’s very early days Elon Musk has tried to define the company as an energy company rather than just a manufacturer of electric vehicles. When Tesla made its $2.6 billion bid for SolarCity the move was viewed as the culmination of the first phase of its “master plan,” which called for Tesla to “provide zero emission electric power generation options.”
Now that plan faces a major test from a publicly traded competitor that’s focused solely on providing residential solar power and the ability to lower costs for its panels through greater efficiencies of scale, according to analysts who track the solar energy sector.
“Sunrun will be freaking big,” Joe Osha, an analyst at JMP Securities, told Bloomberg News. “They are clearly looking for ways to get scale and efficiency.”
Indeed, the combined companies will save roughly $90 million per year thanks to operational efficiencies, according to a statement from Sunrun. And the economies of scale will give the companies even more leverage when they contract with utilities on feeding power into the electric grid.
As Sunrun acknowledged in the announcement of its acquisition of the Blackstone-backed Vivint, the combined customer base of 500,000 homes represents over 3 gigawatts of solar assets. That figure still is only 3% penetration of the total market for residential solar in the United States.
Sunrun had already edged out Tesla for the top spot in residential solar installations, and together the two companies account for 75% of new residential solar leases each quarter, according to data from Bloomberg NEF.
“Americans want clean and resilient energy. Vivint Solar adds an important and high-quality sales channel that enables our combined company to reach more households and raise awareness about the benefits of home solar and batteries,” Sunrun CEO and co-founder Lynn Jurich said in a statement. “This transaction will increase our scale and grow our energy services network to help replace centralized, polluting power plants and accelerate the transition to a 100% clean energy future.”
Even as Sunrun’s $1.46 billion stock (and the assumption of about $1.8 billion in debt) creates a massive competitor to Tesla’s solar business, there’s an opportunity for Tesla to sell more batteries through its residential solar competitor.
Sunrun and Vivint will likely be pushing their customers to add energy storage to their solar installations, and that means using either Tesla’s Powerwall batteries or its own Brightbox batteries manufactured in partnership with LG Chem .
Investors have responded to Sunrun’s latest maneuver by pouring money into the stock. Sunrun’s shares were up more than $5 in midday trading.

“Vivint Solar and Sunrun have long shared a common goal of bringing clean, affordable, resilient energy to homeowners,” said David Bywater, chief executive officer of Vivint Solar, in a statement. “Joining forces with Sunrun will allow us to reach a broader set of customers and accelerate the pace of clean energy adoption and grid modernization. We believe this transaction will create value for our customers, our shareholders, and our partners.”

The Sun Exchange raises $3M for crypto-driven solar power in Africa
South Africa-based renewable energy startup Sun Exchange has raised $3 million to close its Series A funding round totaling $4 million.
The company operates a peer-to-peer, crypto-enabled business that allows individuals anywhere in the world to invest in solar infrastructure in Africa.
How’s that all work?
“You as an individual are selling electricity to a school in South Africa, via a solar panel you bought through the Sun Exchange,” explained Abe Cambridge, the startup’s founder and CEO.
“Our platform meters the electricity production of your solar panel. Arranges for the purchasing of that electricity with your chosen energy consumer, collects that money and then returns it to your Sun Exchange wallet.”
It costs roughly $5 a solar cell to get in and transactions occur in South African Rand or Bitcoin.
“The reason why we chose Bitcoin is we needed one universal payment system that enables micro transactions down to a millionth of a U.S. cent,” Cambridge told TechCrunch on a call.
He co-founded the Cape Town-headquartered startup in 2015 to advance renewable energy infrastructure in Africa. “I realized the opportunity for solar was enormous, not just for South Africa, but for the whole of the African continent,” said Cambridge.
“What was required was a new mechanism to get Africa solar powered.”
Sub-Saharan Africa has a population of roughly 1 billion people across a massive landmass and only about half of that population has access to electricity, according to the International Energy Agency.
Recently, Sun Exchange’s main market South Africa — which boasts some of the best infrastructure in the region — has suffered from blackouts and power outages.

Sun Exchange has members in 162 countries who have invested in solar power projects for schools, businesses and organizations throughout South Africa, according to company data.
The $3 million — which closed Sun Exchange’s $4 million Series A — came from the Africa Renewable Power Fund of London’s ARCH Emerging Markets Partners.
With the capital, the startup plans to enter new markets. “We’re going to expand into other Sub-Saharan African countries. We’ve got some clear opportunities on our roadmap,” Cambridge said, referencing Nigeria as one of the markets Sun Exchange has researched.
There are several well-funded solar energy startups operating in Africa’s top economic and tech hubs, such as Kenya and Nigeria. In East Africa, M-Kopa sells solar hardware kits to households on credit, then allows installment payments via mobile phone using M-Pesa mobile money. The venture is backed by $161 million from investors including Steve Case and Richard Branson.
In Nigeria, Rensource shifted from a residential hardware model to building solar-powered micro utilities for large markets and other commercial structures.
Sun Exchange operates as an asset free model and operates differently than companies that install or manufacture solar panels.
“We’re completely supplier agnostic. We are approached by solar installers who operate on the African continent. And then we partner with the best ones,” said Cambridge — who presented the startup’s model at TechCrunch Startup Battlefield in Berlin in 2017.
“We’re the marketplace that connects together the user of the solar panel to the owner of the solar panel to the installer of the solar panel.”

Sun Exchange generates revenues by earning margins on sales of solar panels and fees on purchases and kilowatt hours generated, according to Cambridge.
In addition to expanding in Africa, the startup looks to expand in the medium to long-term to Latin America and Southeast Asia.
“Those are also places that would really benefit from from solar energy, from the speed in which it could be deployed and the environmental improvements that going solar leads to,” said Cambridge.

The man behind Tesla’s Powerwall is now pitching an all-in-one power management system for homes
Arch Rao, the former head of product at Tesla who was behind the company’s Powerwall home energy storage is system, is back with a new company pitching energy management and efficiency for homes.
Span is looking to upgrade the electrical fuse box for homes with a digital system that integrates into the existing circuit breaker technology that has been the basis for home energy management for at least a century.
Rao and his team are looking to make integrating renewable power, energy storage and electric vehicles easier for homeowners by redesigning the electrical panel for modern energy needs.
“We packaged the metering controls and compute between the bus bar and the breaker,” says Rao. “Energy flows through the panel through a breaker bar and the breaker bar has tabs that you slot your breakers into… that tab is usually a conductor. We have designed a digital sub-assembly that packages current metering, voltage measurement and the ability to turn each circuit on or off.”
The technology is meant to be sold through channels like solar energy installers or battery installers. The company already has plans to integrate its power management devices with energy storage systems like the ones available from LG .
Initially, Span expects to be selling its products in states like California and Hawaii where demand for solar installations is strong and homeowners have significant benefits available to them for installing renewable energy and energy efficiency systems.
For homeowners, the new power management system means that they have control over which parts of the home would be powered in the event of an outage. The company’s technology connects the entire home to a renewable system. Using existing technologies, installers have to set up a separate breaker and rewire certain areas of the home to receive the power generated by a renewable energy system, Rao says.
That control is handled through a consumer app available to download on mobile devices.
Span is backed by a slew of early investors, including Wireframe Ventures, Wells Fargo Strategic Capital, Ulu Ventures, Hardware Club, Energy Foundry, Congruent Ventures and 1/0 Capital, and intends to raise fresh cash before the end of the year. Rao said the round would be “in the low double digits” of millions.

Apple leads corporate American solar energy usage
Apple led the way in solar usage as technology companies step up their development of renewable energy projects to offset their carbon emissions.
That’s the word from the Solar Energy Industry Association in its latest tally of leading corporate solar energy installers across the U.S.
Last year, Apple installed 400 megawatts of solar capacity to lead all companies in the U.S.
“Top companies are increasingly investing in clean, reliable solar energy because it makes economic sense,” said Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association (SEIA), in a statement. “[And] corporate solar investments will become even more significant as businesses use solar to fight climate change, create jobs and boost local economies.”
Four of the top 10 corporate solar users in the U.S. were tech companies. Amazon was No. 2 on the Solar Energy Industry Association’s list of companies tapping solar energy to power their businesses. The data center company Switch and search giant Google (a subsidiary of Alphabet) came in as the fifth and sixth companies.
“Playing a significant role in helping to reduce the sources of human-induced climate change is an important commitment for Amazon,” said Kara Hurst, director of Sustainability, Amazon, in a statement. “Major investments in renewable energy are a critical step toward addressing our carbon footprint globally. We will continue to invest in these projects and look forward to additional investments this year and beyond.”
The price for solar continues to come down, which is increasing the adoption — and scale — of solar installations in the U.S.
According to the SEIA, the biggest jump in solar installations have happened in the last three years. In all, 7 gigawatts of solar capacity has been installed at commercial locations, which is enough to power 1.4 million homes.
Of course, these numbers still need to increase even more dramatically for the corporate world to show that it’s serious about addressing climate change. While it’s important to acknowledge the successes of companies that are taking strides to incorporate more renewable energy into their operations, the goal for these massive industrial and technology giants (and really the goal for every institution) should be to get to as close to full decarbonization as possible.
The world has 10 years to wean itself off its current emissions-heavy consumption habits. Increasing solar usage is a step in the right direction, but it’s only a step.
