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.

Memphis Meats raised $161 million from SoftBank Group, Norwest and Temasek
Memphis Meats, a developer of technologies to manufacture meat, seafood and poultry from animal cells, has raised $161 million in financing from investors, including Softbank Group, Norwest and Temasek, the investment fund backed by the government of Singapore.
The investment brings the company’s total financing to $180 million. Previous investors include individual and institutional investors like Richard Branson, Bill Gates, Threshold Ventures, Cargill, Tyson Foods, Finistere, Future Ventures, Kimbal Musk, Fifty Years and CPT Capital.
Other companies, including Future Meat Technologies, Aleph Farms, Higher Steaks, Mosa Meat and Meatable, are pursuing meat grown from cell cultures as a replacement for animal husbandry, whose environmental impact is a large contributor to deforestation and climate change around the world.
Innovations in computational biology, bio-engineering and materials science are creating new opportunities for companies to develop and commercialize technologies that could replace traditional farming with new ways to produce foods that have a much lower carbon footprint and bring about an age of superabundance, according to investors.
The race is on to see who will be the first to market with a product.
“For the entire industry, an investment of this size strengthens confidence that this technology is here today rather than some far-off future endeavor. Once there is a “proof of concept” for cultivated meat — a commercially available product at a reasonable price point — this should accelerate interest and investment in the industry,” said Bruce Friedrich, the executive director of the Good Food Institute, in an email. “This is still an industry that has sprung up almost overnight and it’s important to keep a sense of perspective here. While the idea of cultivated meat has been percolating for close to a century, the very first prototype was only produced six years ago.”

Oil and gas giants Chevron and Occidental are backing tech to combat carbon emissions
Carbon Engineering, a Canadian company developing technology to remove carbon dioxide from the atmosphere and process it for use in enhanced oil recovery or in the creation of new synthetic fuels, has locked in financing from two big industry backers — Chevron and Occidental Petroleum — to bring its products to market.
The undisclosed amount of capital Carbon Engineering raised from the investment arms of two of the world’s largest oil and gas companies — Oxy Low Carbon Ventures and Chevron Technology Ventures — will be used to commercialize its technology at a time when legislation in California and British Columbia are making low-carbon fuels more economically viable, according to a statement from the company’s chief executive, Steve Oldham. The company had already managed to nab Microsoft co-founder Bill Gates as an investor.
Gates is one of several big-name backers to be drawn to renewable energy technologies in the face of a steadily warming planet that’s rapidly approaching a tipping point of no return when it comes to global climate change. Together with a group of other multi-billionaires, including Marc Benioff, Jeff Bezos, Michael Bloomberg, Richard Branson, Jack Ma, Masayoshi Son and Meg Whitman, Gates launched a $1 billion fund called Breakthrough Energy Ventures last year to back companies that are developing things like new energy storage and water production technologies.
The Squamish, B.C.-based Carbon Engineering isn’t in the Breakthrough portfolio, but is one of several companies working on making economically viable a technology called “direct air capture” of carbon dioxide.
At the company’s pilot plant in Squamish, air gets hoovered up by giant fans into a processing facility where it is treated with potassium hydroxide, which captures and holds the carbon dioxide. Then more chemicals and heat are added to the mix to create millions of small white pellets — which contain higher concentrations of the carbon dioxide.
After that, the pellets are heated again to create a gas that is almost pure carbon dioxide. That gas can be either sequestered underground (a proposition with no economic benefit for Carbon Engineering at the moment) or converted back into fuels or chemicals, or used in enhanced oil recovery.
Carbon Engineering and competitors like ClimeWorks or Global Thermostat claim they can remove carbon dioxide from the atmosphere for roughly $100 per ton, or a bit less once they can get to scale. To make money though, they’ll need to refine that carbon dioxide into some sort of product — likely a fuel, which will return that carbon to the atmosphere.
Other companies tackling carbon capture, like Newlight Technologies and Opus12, convert the carbon into plastics or chemicals, while companies like CarbonCure aim to turn the captured carbon into a cement replacement.
While these products from carbon emissions are available, they’re not yet commercially viable at a significant scale. Oldham told National Public Radio that the fuel Carbon Engineering manufactures is roughly 20 percent more expensive than regular gasoline.
That’s why states like California are putting incentives in place to offset the added costs of using these low-carbon products.
Carbon Engineering has already spent $30 million to develop its process, while Climeworks raised $31 million last year to develop its own version of this carbon capture technology.
Not all climate watchers are convinced that these kinds of negative emission technologies are the answer. They argue that it’s less expensive to use renewable energy and other carbon-free energy sources than to take carbon dioxide out of the air.
At this point, though, emission reductions may not be enough. Given the dire reports coming out of the Trump administration and the Intergovernmental Panel on Climate Change, it’s going to take pretty much a combination of everything that humanity’s got to avoid a pretty catastrophic fate for a pretty large portion of the world’s population.
Even the companies that have been notorious for their contributions to the climate crisis that the world faces are waking up to the need for decarbonization (even if it’s an open question of whether they’re being dragged to the table or sitting down of their own free will).
Oxy Low Carbon Ventures is a good example. Reading the writing on the wall, the firm has invested not just in Carbon Engineering, but another company called NET Power, which purports to have developed a power plant with zero emissions.
“It is a very important time for the air capture field right now,” said Oldham in a statement. “We’re seeing leading jurisdictions, like California and British Columbia, creating markets for low carbon fuels and technologies like DAC, through effective climate policy. These efficient market-based regulations, and action from energy industry leaders like Occidental and Chevron, show the power of policy in driving innovation and achieving emissions reductions while delivering reliable and affordable energy.”
