Mesh-grids for electrifying remote communities

Spotted: Following an increase in the number of people worldwide without access to electricity in 2022, 2023 is seeing a decline, with the International Energy Agency (IEA) highlighting local home solar systems as one of the main reasons for the improvement. That growth, however, is still deemed too slow to meet the United Nations’ Sustainable Development Goal (SDG) 7 of affordable, reliable, sustainable, and modern energy for all by 2030. 

Determined to assist the 700 million people without electricity, Okra Solar uses mesh-grids to bring hyperlocal solar energy systems to the world’s most remote communities. Mesh grids use low-voltage connections to distribute power between homes that are in very close proximity to each other.  

Any other type of network requires far more infrastructure such as cables, poles, and materials capable of containing higher voltage currents, all of which are key reasons why most of the world’s isolated communities remain without electricity. Okra Solar’s solution allows last-mile energy delivery by providing either standalone home solar (SHS) systems or a small number of connections between neighbours.  

An Okra pod is installed in every home, and the Internet of Things (IoT) capability makes sure that energy flows where it is needed in the network, which allows residents to consume more than they would otherwise generate on their own. The IoT also provides remote monitoring of the system via cellular data or Wi-Fi, and the pods are powerful enough to support appliances like freezers, power tools, and a variety of lights. 

Homeowners can make payments via mobile, and the cloud connection means that the system’s always-on monitoring ensures that homes have the required minimum amount of energy. The Okra Solar team creates a least-cost-of-electrification plan for every location and includes detailed cost breakdowns along with a comparison to alternatives such as microgrids.  

Okra Solar’s mesh-grids are being used by more than 14,000 people across four different countries, and the company recently raised $12 million (around €11.4 million) to scale further the deployment of its panels and system.  

Other recent solar power innovations in Springwise’s archive include the repurposing of old EV batteries for off-grid solar energy and a rent-to-own solar panel programme that makes renewable energy far more accessible.

AI and remote sensing technology for managing water risk

Spotted: By 2030, the world’s communal demand for fresh water is expected to outstrip supply by 40 per cent. How to avert this crisis is a question many innovators, researchers, and agencies are working to answer. And sustainable management of the water that is currently available is a crucial aspect of the global solution. 

Understanding the health of the world’s bodies of water, along with current and potential future risks is vital, and San Francisco-based technology company Waterplan has created a platform that uses remote sensing and artificial intelligence (AI) to track, analyse, and mitigate the risk to global water supplies.  

The platform helps organisations of any kind plan for the future by protecting water supplies now. The highly detailed reports include data from regulatory reviews, watershed authorities, industry analysis, scientific research, and more, with information presented in easily navigable formats. Clients view data by site and can see at a glance which areas need risk mitigation first.  

The reports are structured in a way that makes them usable for investors, and client input helps shape what areas the AI tracks. Sustainability managers use the platform to track progress against targets and measure the efficacy of various interventions. Operations managers can use the platform to maintain peak productivity across all processes and locations, as well as predict adjustments needed based on changing conditions.  

With the need for robust data continual, Waterplan recently closed an oversubscribed series A financing round that raised $11 million (around €10 million).  

Cleaning polluted water is one way to improve the quantity of supply, and examples from Springwise’s archive include a membrane that generates electricity while cleaning wastewater and a modular sewage treatment plant that fits inside a shipping container.

A platform connects US tech startups with remote developers in Latin America

A platform connects US tech startups with remote developers in Latin America

Spotted: Thanks to the COVID-19 pandemic, remote working infrastructure has improved dramatically, while remote working practices have become culturally embedded within many organisations. Highly digitised industries saw the biggest adoption of remote working, with the OECD estimating that, on average, more than  50 per cent of high-tech workers worked from home during the pandemic. Indeed, Apple employees have become so used to remote working that a group of them have publicly pushed back against calls from top management to return to the office.

But what impact will increased acceptance of remote working have on the job market for tech? One possibility is that it will encourage more companies to outsource tasks to freelance developers in lower cost countries. But for Philadelphia-based startup Teilur, ‘outsourcing’ is a dirty word associated with short-term transactional relationships. Instead, the talent platform is focused on helping US tech startups build meaningful, long-term relationships with Latin American developers who share their mission and values.

What does this mean in practice? At the heart of Teilur’s platform is a network of over 400 pre-vetted growth marketers, data professionals, and software developers. US tech companies can dip into this pool of talent to find their next valued team member. Teilur then takes care of cumbersome administrative tasks such as international contract compliance and payroll. Crucially, for US firms, Latin America can provide workers who operate in the same timezone as their US-based counterparts, making collaboration easier. And to incentivise long-term relationships, candidates on the Teilur platform get paid salaries two to three times higher than what the big tech companies offer locally.

Teilur argues that its platform benefits both startups and developers. It claims that companies can save up to 60 per cent in salaries, while candidates receive better pay than is available elsewhere in their local market. Teilur is also committed to pricing transparency with a promise to never charge more than 25 per cent of what the hiring company pays for a candidate – a competitive rate in a market where agencies routinely charge up to 50 per cent. Teilur also pledges to only charge companies if they actually hire a candidate.

With a global talent gap looming on the horizon, Springwise is spotting a number of talent tech innovations such as a language-learning app that connects candidates from marginalised groups with employers in the digital economy, and an AI-powered training platform that predicts future skills gaps.

Ground-breaking new batteries for remote communities

Ground-breaking new batteries for remote communities

Spotted: UK-based renewable energy and battery specialist AceOn has teamed up with battery pioneer AMTE Power to use next generation solar-powered energy storage units to bring electricity to remote sub-Saharan African communities. AceOn has developed the AceOnPES (portable energy storage) power unit which will run on sodium-ion battery cells produced by AMTE. 

While conventional lithium-ion batteries use raw materials—such as lithium and cobalt—that are in finite supply, sodium-based cells use sodium instead. This offers huge potential advantages, as sodium is plentiful almost everywhere and can be extracted using minimal energy. This could allow wider and cheaper battery manufacture.

Because they lack heavy metals, sodium batteries are also much easier to recycle, and their use would eliminate much of the risk of pollution from both mining and battery disposal. The two companies point out that sodium-ion batteries have huge potential for application in energy storage – where there is a need to vastly scale-up production of safe, stable battery technology to support the growth of renewable energy.

Mark Thompson, managing director of Telford-based AceOn, explains that the new battery chemistry can make global electrification more sustainable. “We’ve been championing sodium-based technology for years as a sustainable alternative to lithium-ion, and thanks to our partnership with AMTE, we can finally use it in our product… These batteries are the future.” 

Efficient and sustainable energy storage is vital for the large-scale use of renewable energy. At Springwise, we have recently covered innovations in this area such as a technology that yields almost pure graphite from used lithium-ion batteries, and an energy storage system located at the bottom of the sea.
