Beyond the Hype

Nine Underhyped Frontier Technologies

for International Development

Amidst the buzz of AI, truly game-changing technologies are being overlooked.

The Frontier Tech Hub has been scanning the horizon for the breakthroughs hiding in plain sight—the innovations that could make a real difference but rarely make headlines.

The nine technologies below hold real potential to shape a more sustainable, resilient future in the face of a rapidly changing development landscape and the relentless threats of climate change. They’re the complex, unsexy solutions that can power off-grid communities, optimise water cycles and speed up the shift to renewables. 

It’s time to turn our attention away from the traditional hype cycle and bring these technologies into the spotlight. Because the real frontier isn’t about what’s trending—it’s about what can quietly, sustainably transform lives.

Are you ready to discover the Nine Underhyped Frontier Technologies?*

Waste-Powered Energy

What is it?

A system that turns organic waste into biogas and electricity, improving sanitation while reducing pollution.

Watch Area

The social stigma around using human waste will likely slow adoption and investment.

Best used in

Off-grid villages, refugee camps and farms managing large amounts of waste.

Works Well With

Circular economies, decentralised energy grids, sanitation and public health initiatives.

Today:

Small biogas digesters for the home.

Tomorrow:

Using microbial fuel cells that generate electricity.

Beyond:

Sanitation systems that turn waste into power and agricultural biofertilisers.

Bioremediation

What is it?

Using microbes, fungi, and plants to clean up polluted environments and rebuild healthy ecosystems.

Watch Area

Bioremediation works at nature’s pace, so results take longer than chemical methods.

Best used in

Old industrial sites, mining zones, farms polluted with pesticides and oil spills.

Works Well With

Agroecology, community-led restoration, and environmental justice initiatives.

Today:

Plants help absorb toxins from soil.

Tomorrow:

Fungi and bacteria speed up cleanup.

Beyond:

AI-enhanced biosensors create super-efficiencies.

Algal Photobioreactors

What is it?

An enclosed system that grows algae at scale. Algae can capture CO₂, produce biofuels, and clean wastewater.

Watch Area

Algae cultivation needs precise conditions and delicate management to thrive.

Best used in

Carbon capture projects, renewable energy farms, wastewater treatment, and climate resilience initiatives.

Works Well With

Circular bioeconomy, sustainable farming and aquaculture, and the voluntary carbon market.

Today:

Open ponds grow algae for fuel.

Tomorrow:

Enclosed photobioreactors use optimised strains of algae.

Beyond:

AI-monitored algae systems integrated into cities and industries.

Artificial Biosensors

What is it?

A new generation of biosensors that identify pollutants, toxins, and health risks in real-time.

Watch Area

Works best when regularly maintained, because they are sensitive to environmental conditions.

Best used in

Water and food safety, remote healthcare, and environmental monitoring.

Works Well With

Wearable biosensors, sustainable agriculture, low-cost diagnostics, and pollution control.

Today:

Paper-based biosensors.

Tomorrow:

Durable, reusable bioelectronic sensors.

Beyond:

Self-powered, biodegradable biosensors across ecosystems.

What does it mean to be “Underhyped”?

We can assess tech hype by comparing two things: attention (how much buzz a technology gets—like news, patents, or research) and potential (how well it could support development goals, such as economic, social, or environmental impact).

“Underhyped Frontier Technologies” possess significant capacity to address locally defined priorities (potential) yet do not receive attention due to dominant narratives that prioritise top-down, market-driven solutions.

Recommendations

Through a series of recommendations, we aim to support policymakers and regulators; funders and investors; technology implementers and practitioners.

These 5 recommendations offer: a long-term perspective for frameworks that safeguard technological sovereignty and prevent monopolisation; concrete actions to ensure ethical adoption, security, and community empowerment; and guidance on participatory and regenerative technology design.

How do you measure hype?

Taking a list of 142 technologies to just 9 demands a multi-disciplinary approach.

Find out how we designed a “hype” scorecard, assessed scaleability using foresight methods and convened a Global Brain Trust of experts and community representatives to provide ethical, cultural, and practical insights. 

Our methodology supported a final list of technologies prioritising accessibility, autonomy, scalability, social justice, and ecological balance.

What does the future hold?

As the world constantly changes, it's tough to predict which technologies will shape our lives a decade from now, and even harder to imagine how they will do so.

Foresight is a systematic way to look into the future that can help anticipate challenges and opportunities. We used this method to consider possible futures for the nine underhyped technologies.

A huge thanks to our Global Brain Trust, without whom this work would not have been possible

Given the pace of technological change and the increasingly complex contexts in which we’re working it’s vitally important for FCDO staff to be able to continue to harness technologies to achieve development goals.

Hold on though, because this isn’t the first Top Tech List the Hub has published…

Over the past decade, the Frontier Tech Hub has been on the cutting edge of emerging tech uses for development and diplomacy, supported by key moments of evidence-driven curiosity.

Ten years ago, the Hub was set up to respond to a milestone piece of research into Ten Frontier Technologies for International Development, to test and learn about them in the real world.

Five years later, we surfaced and published the Top Ten Frontier Technologies for Climate Action, calling for Pioneers to build out our collective learnings around their use.

Since 2016, we have tested 91 solutions across 30 countries, building an expanding portfolio to put each of these critical moments of insight to the test in lean, agile ways, reflected in the timeline below.

And now, we’re publishing this third list with the next Frontier: the Nine Underhyped Frontier Technologies for International Development.
