Energy innovation via underwater wave tech

Spotted: There is a lot of energy embedded in ocean waves. In fact, according to the US Energy Information Administration, waves off the coast of the US alone have a theoretical energy potential of 2.64 trillion kilowatt-hours – enough to meet around 64 per cent of the country’s 2021 energy demand.

Hoping to tap into this abundant but underexploited energy source is Finnish company AW-Energy with its WaveRoller wave energy converter. WaveRollers are hinged panels that harness the power of ocean waves as they move back and forth. Interior hydraulics and an integrated power storage system convert the movement of the waves to electricity.

Company CFO Matthew Pech told Springwise, “The original inspiration for the technology was when the inventor, Rauno Koivusaari, was diving into a shipwreck. He saw a cargo hatch moving with the motion of the water, and tried to stop it with a plank of wood, which shattered. This sparked the idea that there was a large amount of energy available that could be tapped into.”

The zero-emissions devices are mostly or completely submerged in the water. They are fixed to the ocean floor anywhere from half a kilometre to two kilometres away from shore, at depths ranging from eight to 20 metres. That near-shore location makes the technology particularly useful as it minimises the chances of faults in the subsea cables used to connect WaveRollers to the on-shore grid infrastructure. One WaveRoller generates 350 to 1,000 kilowatts of energy depending on the size and strength of the waves in each location, and multiple devices can be used together to boost energy generation.

The devices complement existing renewable energy sources by providing additional power and filling in gaps in provision from the more intermittent renewables of wind and solar. WaveRoller’s power storage system comes in a variety of sizes, for utility-scale use and to provide rapid response support for fluctuations in grid supply. AW-Energy also created a smaller-scale WaveRoller-X. All components of the smaller device fit within a single shipping container, and the fully built device is small enough to be suitable for remote locations and those with limited sea access.

AW-Energy is currently developing projects with customers, with a goal of deploying its first commercial array of WaveRollers within the next couple of years.

Springwise’s library contains a number of innovations that harness the power of water, including technology that harnesses the power of raindrops and IoT software that improves hydropower plants’ efficiency by automating certain tasks.

Helping cleantechs find and use low-carbon feedstocks

Spotted: The International Energy Agency (IEA) calls for “an accelerated increase in modern bioenergy use [alongside] a phase-out of traditional use of biomass.” Most traditional uses of biomass involve burning organic materials over an open fire, something that the Net Zero Emissions (NZE) scenario hopes to eliminate by 2030. 

One challenge in making the best use of available biomass is connecting manufacturers who want to use the material as feedstock in chemical and industrial processes with those in the agriculture and forestry industries who produce it. US-based climate-tech company Loamist has built a ‘Biomass Explorer’ platform in the hopes of making use of the eight billion tonnes of biomass that is wasted globally every year.

Using real-time mapping and data visualisation, the Biomass Explorer tool helps companies seeking more sustainable supply chains find, use, and track low-emission feedstocks from a variety of sources. For owners of biomass materials, it’s easier to earn additional income, as the Explorer tool makes them visible to more buyers.

Users generate custom reports and build directories of suppliers and supplies, and the tool also validates supply chain carbon outputs. With the data, companies can also choose manufacturing locations that are close to biomass sources. Loamist’s goal is to use more than 100 million tonnes of waste biomass by 2030, as organisations around the world swap fossil fuels for carbon-negative or carbon-neutral chemicals, fuel sources, and materials.

In early 2024, Loamist announced $1 million (around €922,000) raised in pre-seed funding. The company plans to continue developing the Biomass Explorer tool and create additional products as the industrial biomass industry matures.

From cellulose to coffee cups, innovations in Springwise’s library showcase the variety of types of waste that can be transformed into biomass.

Providing modular bamboo homes at affordable prices

Spotted: Myanmar is facing a severe housing crisis, as conflict triggered by the military takeover in 2021 has resulted in the internal displacement of around 1.95 million people, according to the UN Refugee Agency. Social enterprise Housing NOW, founded by Myanmar-based design group Blue Temple, is working to build affordable housing using an innovative and sustainable technique.

Housing NOW uses bamboo as a construction material for building prefabricated, modular structures at a cost of around $1,000 (around €923) per unit. Using computational tools, the company generated a structure optimised to respond to forces such as earthquakes and wind loads.

Because larger-diameter bamboo is more expensive, small-diameter bamboo was used instead, and bundled together to produce a structure that’s stronger than conventional, load-bearing, large-diameter bamboo. The hybrid construction technique allowed the creation of prefabricated ‘structural frames’, which were then combined with local construction and assembly of the remaining parts of the house. The result is a large-scale and affordable housing solution.

In 2022, Housing NOW started a crowdfunding campaign on Indiegogo, which raised enough funding to construct six modules as part of a pilot project. The company plans to continue raising funds and expanding the project.

The promise of bamboo as a renewable resource is catching on. Springwise has also spotted a platform for investing in low-impact bamboo and the development of land for sustainable bamboo growth in Jamaica.

Accessible environmental info for non-specialists

Spotted: Space technology analysts expect the growing concern over the effects of climate change to increase demand for satellite-based Earth Observation data and to hasten the development of additional innovations within the industry. More satellites will create more data, and there is already a lot available. So much, in fact, that it can be difficult for organisations to know what to focus on and how to make the best use of the information.

Hoping to tackle that information overload is Netherlands-based Meteory. Meteory combines public and private satellite data with its proprietary machine learning, AI, and data science processes to provide organisations with clear, usable information on which to base their sustainability decisions. No matter the industry, Meteory can help businesses understand what is happening on the ground and how conditions are changing.

Meteory’s platform combines 40 years of historical data with real-time datasets and uses machine learning to analyse terabytes of data in seconds. Organisations customise their dashboard to track Environmental, Social, and Governance (ESG) goals and see how different decisions will affect them. With Meteory’s platform, companies don’t have to build their own analysis systems, but can still access essential insights and indicators in real time.

Meteory brings together a range of data types, including radar, ocean, atmospheric gases, soil information, public forest monitoring, carbon dioxide emissions, and more. As well as the platform for real-time tracking and analysis, the company offers automated summary reports that users can set to receive at any frequency.

Satellites are helping organisations in a number of fields better care for the land, with innovations in Springwise’s library including a platform for preventing forest fires and a new method for hyperlocal rain forecasts.

Could VR content boost empathy for the environment?

Spotted: It’s vital that young people learn about global warming and the importance of living more sustainably. Without climate change literacy, many won’t be able to adapt to the economic and environmental impacts of climate change. This is especially the case in Africa, where countries are disproportionately vulnerable to climate change. Now, one startup is changing how young people learn about the dangers of climate change and plastic pollution through virtual reality (VR). 

Ukwenza VR is a startup based in Kenya that offers educational VR content for classrooms and extracurricular learning. The startup’s VR experience transports students to realistic digital simulations of environments affected by plastic pollution and climate change. Students witness virtual representations of polluted water bodies, littered streets, and devastated habitats in Kenya and beyond, showing them the impact of plastic waste on marine life, land animals, and human health through the VR headsets.  

The startup works with schools and educators to create and deliver content that meets learning standards that serve the community. Ukwenza mainly focuses on schools from low-income areas that cannot access such digital opportunities – where communities are most affected by plastic pollution and accumulated sewage and garbage. 

Leveraging corporate social responsibility (CSR) programmes and other funders, Ukwenza can deliver VR experiences to public schools that would otherwise be unable to afford them. In private schools, by contrast, Ukwenza works with parents who pay a subscription for students to access the content.

As the world becomes increasingly environmentally conscious, it’s essential that young people grow up with an awareness of why and how they can also make a difference. Springwise has spotted many innovators finding ways to educate young people, including by using Minecraft and fairytales to better explain sustainability issues.

Turning marine CO2 emissions into useful pebbles

Turning marine CO2 emissions into useful pebbles

Spotted: Proposed international regulations will mandate at least a 40 per cent reduction in CO2 emissions from ships by 2030. Alisha Fredriksson, co-founder and CEO of London-based company Seabound, discovered that shipowners lack feasible options to meet this requirement.

The realisation motivated Fredriksson to develop a solution, leading to Seabound’s lime-based carbon capture equipment, which can be installed near a ship’s smokestack to capture up to 95 per cent of CO2 emissions from the exhaust.

To curb the release of greenhouse gases into the atmosphere, Seabound implements its carbon capture system near its funnel. Quicklime pellets are consistently introduced into the device, undergoing chemical reactions with CO2 in the exhaust to form limestone. Upon docking, the pellets can then be used for future CO2 capture on other vessels, sold as construction materials, or divided into pure CO2 for various purposes.

Seabound’s innovative technology holds promise for various vessel types, including container ships, cruise ships, and dry bulk carriers. What sets this company apart is its seamless retrofitting capability for existing ships, rendering decarbonisation of shipping more accessible, rapid, and scalable.

The startup recently achieved a key milestone when, in partnership with global shipping company Lomar, it completed a successful pilot of its technology on-board a commercial container ship. The 240-metre-long vessel, which was chartered by liner shipping company Hapag-Lloyd, was equipped with a prototype version of the system that captured around one tonne of CO2 per day. Having completed the pilot, Seabound will now progress to creating its first full-scale systems, which it hopes to deliver commercially from 2025 onwards.

Springwise has previously spotted other innovators looking to make the maritime industry greener, including a startup that’s developed a ship-cleaning robot and a company that’s presented concept designs for a zero-emission ship.

No silver bullet but some promising signs of progress

No silver bullet but some promising signs of progress

Soline Guerineau is Head of Commerical Strategy, Sustainability at ICIS, an independent commodity intelligence service. She shares where she sees momentum in hard-to-abate sectors and where collaboration with startups may drive emissions reductions.

“The state of play right now is that the chemicals industry is the largest industrial consumer of energy and ranks third when it comes to direct CO2 emissions – after steel and cement production. According to the International Energy Agency, the chemicals sector emitted 935 megatonnes of CO2 in total in 2022. On a product-by-product level, carbon footprints are tapering, yet the industry‘s overall emissions total is increasing because demand is increasing. At ICIS, we expect the global consumption of chemicals to rise by 23 per cent from 2022 to 2030, despite the macroeconomic challenges in 2023.”

So, what can be done? Soline believes there are a few levers for the chemical industry to pull that are similar to those for other heavy industries. First, the supply chain is important – scope 3 emissions make up 80 per cent plus of chemical industry total greenhouse gas emissions. And sourcing low-carbon suppliers can be a challenge.  

Energy sources are another challenge. “Coal is still the main source of energy in some emerging markets, but we see the more mature industry players moving towards electrification by investing in new facilities. For example, LyondellBasell recently announced a memorandum of understanding with Technip Energies and Chevron Phillips Chemical to pursue electric steam cracking furnace technology.

“Further development in this area is dependent on the elevation of the grid and the availability of renewable power, but we are seeing an interesting uptick in power purchase agreements (PPAs) – a type of long-term renewable energy contract – for heavy industries in general, with companies trying to manage their scope 2 emissions while also attempting to control cost.”

Beyond scope 3 and energy sourcing, there are some further drivers. “For example, waste heat recuperation and efforts to make energy consumption more cyclical are emerging, carbon capture technologies have a role to play but are not yet scalable, and there is also a key thread around the materials transition. For the chemicals industry, this is around feedstocks and moving away from virgin fossil feedstocks to biomass.” 

At ICIS, Soline says they see progress in recycling and more circular business models, and while the recycled plastics market remains smaller than virgin markets, it is growing. The market will benefit from regulation that is set to come into play – The European Strategy for Plastics, for example, sets the objective that all plastic packaging placed on the EU market will be reusable or easily recyclable by 2030. Crucially, anyone exporting to the bloc will need to comply, which will really accelerate upward market trends.  

However, she states that: “There is no silver bullet in terms of what is likely to have the biggest impact. I think there is a question around leadership and fresh approaches, and I also wonder what more women in the industry would bring? For our CEO of the year awards 2023, we nominated an emerging leader, Jodie Morgan, the CEO of Nexus Circular, a US Series-C-stage company that provides advanced recycling to several larger petrochemical companies. There needs to be more collaboration with innovative startups and industry disrupters like this (or acquisitions) to accelerate technology pathways and drive further progress in the areas that are still in their early stages.”

Cooling large commercial buildings with ice

Cooling large commercial buildings with ice

Spotted: In the US alone, around 74 per cent of all energy is used by buildings, and of that figure, 50 per cent of the peak hour consumption is used keeping buildings cool with air conditioning. This is where startup Nostromo Energy comes in, with its new methodology for energy storage that could relieve the power grid of some of the strain – and environmental cost – of cooling buildings. The company’s ‘IceBrick’ system utilises off-peak hours energy to freeze water in an ice brick array, which can then be used to chill water for cooling at a later point.

Today’s commercial-scale air conditioners are energy-intensive because they constantly run ‘chillers’ to cool water, which then circulates in a building, cooling the air. Nostromo’s system reduces the use of chillers by creating ice in an array of capsules at off-peak times – a process that ‘stores’ cooling energy. The building’s circulated water can then be passed through the array to be cooled at peak times, without the energy drain of constantly running the chillers. In fact, the chillers can be turned off when the IceBrick is in use, reducing electricity consumption at key moments.

The system is extremely modular and can be fitted to a building’s available rooftop and basement space. The technology also has good longevity as water can be frozen and unfrozen for many years with only minimal degradation.

A cloud-based management platform is used to control the system and make adjustments depending on the business’s particular goals. For example, the system can be optimised for financial gains or to reduce carbon emissions, maximise electric vehicle charging capacity, or provide enhanced backup. Nostromo works with a business’s engineers to install the IceBrick system on new builds or as a retrofit, with the company taking care of permitting and installation.

Springwise has also spotted other innovations using ice for cooling, such as fridges for areas without constant power. The Springwise library also contains other innovations reducing the impact of air conditioning, such as a system that uses salt water to remove moisture, and a 3D-printed air conditioning system.

A circular platform finds new lives for used equipment

A circular platform finds new lives for used equipment

Spotted: In France, a recently enacted law prohibits companies from destroying their unsold non-food goods without first trying to resell, donate, or recycle them. To promote the circular economy and help companies meet this requirement, startup CircularPlace has created a platform that optimises the collection and management of unsold goods, second-hand equipment, and returns. The digital marketplace matches businesses and charities with available products that are either unsold inventory, returns, or used, non-food items.

Items are first offered for sale, then for donation. The marketplace is free to use, and CircularPlace takes a 10 per cent commission on every sale. Products listed for sale are auctioned, and after the seller confirms the condition of the items, the buyer receives a tax receipt and certificate of sale. Items available for donation go through a similar process.

After being listed for both sale and donation, CircularPlace provides owners of items unable to find a new home with a network of verified recyclers. And as a last resort if products are unable to be recycled, CircularPlace issues a certification that allows the owner to discard the products without falling foul of waste regulations.

For organisations large enough to utilise an internal marketplace, CircularPlace provides a white-label platform to rent, share, and exchange products. Gamification features help make it fun for employees to track team footprints, and for all users of the marketplace, CircularPlace provides reports on the volume of emissions prevented by every transaction.

Industries notorious for the volume of their waste are beginning to explore circularity, with innovations in Springwise’s library showcasing options for reusing electronics and deadstock material.

Filter cartridges purify the water from most taps

Spotted: By 2050, analysts expect global demand for water to outstrip supply by nearly 60 per cent. And ageing infrastructure makes it difficult for cities to use the latest technologies to store and distribute potable water. One potential solution to the very complex problem of providing communities with clean, fresh water is to filter what is available. 

Tunisian greentech company Dracoss has built a purifier that attaches to most types of taps and works without electricity, making it accessible to organisations with limited financial means. The ceramic filter cartridges last for three to six months, and the filtering process can be turned off to allow unfiltered water to run through the system as a means of extending the life of the cartridge.

The tap water filter captures every contaminant that is 0.3 microns in size or larger, which includes sediment, rust, parasites, and algae. Dracoss’ design includes activated carbon granules to improve the taste of the filtered water, and the system is easy to install. The company provides both an installation and maintenance video for support in installing the filter and changing the cartridge.

For larger organisations, Dracoss also offers a greywater recycling machine that cleans used water from dishwashers, baths, sinks and more. The recycled water is clean enough for use in laundry, toilets, and irrigation. The system can reduce overall water consumption by up to 50 per cent.

As well as filters and greywater recycling, Dracoss also provides educational seminars on water scarcity and various solutions, and the company ships internationally.  

From small-scale, plug-and-play water sanitation systems to off-grid nanogrids that provide solar power as well as clean water, innovations in Springwise’s library demonstrate the diversity of solutions needed for this intricate world challenge.
