Transforming agriculture with carbon-neutral ammonia production

Spotted: Today, producing ammonia accounts for around 1.3 per cent of CO2 emissions from the world’s energy system, because the catalytic process requires extremely high temperatures and pressures that are normally achieved using fossil fuels. The vast majority of ammonia is used to create nitrogen fertilisers, making it a vitally important compound in global food production. Hoping to make it easier for farmers to produce ammonia cleanly is Danish startup NitroVolt.

The company has created a patent-pending “Nitrolyzer” that allows a previously carbon-producing process to become entirely carbon neutral and fossil free, with the only necessary inputs being green energy, water, and air. Within the Nitrolyzer, lithium salt is reduced to lithium metal, which then reacts with nitrogen to form nitrides. Hydrogen (which is produced by hydrolysis) can then react with nitrides to form ammonia. To make the process even more sustainable, the lithium can be reused again and again in the continuous reaction process.

Crucially, the Nitrolyzer was created to tackle the logistical challenges that farmers may face in accessing ammonia. The technology is modular and can therefore be installed wherever ammonia is needed, say on a farm or in a greenhouse. This means that farmers and growers can tailor production depending on their needs, and eliminate the costs and emissions associated with transporting fertiliser.

Recently, NitroVolt raised €750,000 in a pre-seed funding, which will be used to expand the team and help to scale the technology.

Fertilisers play an essential role in growing healthy crops and boosting food security, but currently industrial production methods are highly unsustainable. Luckily innovators are searching for alternatives, including the use of dog waste and seed coatings that reduce the need for fertilisers in the first place.

Revolutionising the poultry industry with carbon-neutral eggs

Revolutionising the poultry industry with carbon-neutral eggs

Spotted: Although not as polluting as cattle or pigs, poultry rearing still contributes around 790 million tonnes of CO2 equivalents each year. The equates to around eight per cent of all agriculture emissions. Much of this comes from feed, heating and lighting, and manure. But now, Dutch egg farm Kipster is pioneering a carbon-neutral approach that could be the future of poultry farming – and the company is bringing it to the US.

Kipster has partnered with Kroger groceries and MPS Egg Farms to bring its sustainable egg farming stateside. Kipster’s techniques begin with reducing greenhouse gas emissions internally as much as possible, and offsetting any remaining emissions with external carbon reduction projects. Internal measures include turning surplus food into chicken feed, rather than growing feed on land that could be used for human food production.

The ‘upcycled’ chicken feed uses by-products from crop and food processing, such as oat hulls and faulty pasta. The upcycled feed has a carbon footprint of around half that of conventional feed. Kipster’s farms are all specially designed to allow the birds to carry out their natural behaviours, reducing the need for trimming beaks and administering antibiotics. Kipster is also the first farm to remove dust, odour, ammonia, and other undesirable particles from the barn air, as well as recovering the heat using a heat pump.

Denise Osterhues, Kroger’s senior director of sustainability and social impact explains: “Choosing Kipster cage-free eggs is an easy way for our customers to help create a more sustainable food system.”

As people become more aware of the emissions cost of rearing animals, many are turning to alternatives – and innovators are keeping up with the demand. Springwise has recently spotted many types of sustainable foods, including cultivated pork made using microalgae, and a sustainable, cocoa-free chocolate.

A purpose-built carbon-neutral brewery – Springwise

A purpose-built carbon-neutral brewery – Springwise

Spotted: As concern for the climate increases, businesses everywhere are working on innovative ways to become carbon neutral. Recently, beverage giant Diageo announced plans to invest €200 million to build Ireland’s first carbon-neutral brewery. The new brewery will brew lagers and ales on a greenfield site in Newbridge, County Kildare. When complete, the brewery will have the capacity to brew 2 million hectolitres of beer, making it Ireland’s second-largest brewing operation.

The new facility will be powered entirely with renewable energy, as well as using the latest process technology to minimise energy and water consumption. The brewery will save an estimated 15,000 tonnes of annual carbon emissions compared to what a similar-sized standard brewery would produce. Construction is expected to begin this year, with brewing operations starting in 2024.

The new brewery is also positive news for the economy of Newbridge and surrounding areas in Kildare, with up to 1,000 jobs created during the construction of the site and 50 permanent positions once it is up and running. Both Diageo and the Irish government hopes the brewery will serve as an inspiration for other businesses.

In going carbon neutral, Diageo is joining a growing number of businesses and industries that are using innovative design and building techniques to save on carbon emissions and water use. Some recent developments in this space include carbon-negative cement production and even carbon-neutral headphones.

A new generation of self-powered carbon-neutral tiny homes

A new generation of self-powered carbon-neutral tiny homes

Spotted: According to a recent report from the National Association of REALTORS, the housing shortage in the US is reaching critical levels. The report estimates that there is currently what the association calls an ‘underbuilding gap’ of 5.5 to 6.8 million housing units since 2001. This shortage is pushing house prices and rents higher. And it’s becoming increasingly difficult for people to find affordable places to live.   

One company that’s looking to address this problem is Cosmic, a San Francisco-based startup that is building tiny houses. The company’s founder, Sasha Jokic, believes that these houses can help fill the gap by creating new rentals. In addition, Cosmic’s houses are designed to be highly energy-efficient – helping to reduce carbon emissions from the housing sector.

Ultimately, Cosmic is working to tackle two challenges simultaneously: the housing shortage and climate change. First, by creating new rental units that can be placed in people’s backyards, Cosmic can help to ease the pressure on the rental market. And second, because tiny houses are much more energy-efficient than traditional homes, they have the potential to significantly reduce carbon emissions. It’s an ambitious goal, but if they can pull it off, it could have a huge impact.

Cosmic’s ultra-efficient homes start at just 350 square feet, but they come packed with high-tech features that allow them to function as both a primary residence and a secondary getaway. The secret to the tiny house’s success is its standardised frame, which includes built-in solar power and batteries. Each tiny house also includes a built-in roof and floor, and mechanical, electrical, and plumbing systems.

The modular design means that the houses can be assembled quickly and easily, without the need for construction crews. And because the houses are optimised to be energy-efficient, they can be powered entirely by renewable energy sources. Lithium-ion batteries store energy from the solar panels, with the option to return any extra energy produced back to the grid. Alternatively,t, the excess energy can be used to power the main house, or an electric car.

Financial models for the houses are being arranged, with prices starting at $190,000 (around €176,000). There might also be a second option starting at $150,000 (around €139,000), where Cosmic would own the renewable energy infrastructure and the extra power generated in return for free power for the backyard and discounted power for the main house.

Other tiny home innovations spotted by Springwise include tiny houses for the homeless, an off-the-grid house on wheels, and a tiny home using passive design.
