Jeju Carbon Neutrality 2035: Pioneering Green Hydrogen and V2G Integration

You step onto the windswept shores of Jeju Island and sense something big is brewing. South Korea’s largest island—home to about 676,000 people and famous for its volcanic peaks, lush forests, and UNESCO World Heritage spots—is feeling the heat of climate change. Shifting weather patterns are threatening coral reefs and rattling the livelihoods of those who rely on tourism, agriculture, and fisheries. That urgency has everyone talking: Jeju’s leaders have set a bold marker—full Jeju carbon neutrality 2035, a whopping fifteen years earlier than the national goal. And they’re sparing no effort, from smart policies to cutting-edge tech and partnerships across government, industry, and global experts.

Born from the Carbon-Free Island 2030 Initiative

Back in 2012, Jeju threw down the gauntlet with its pioneering Carbon-Free Island 2030 initiative, pledging to run on 100% renewable electricity by 2030. That ten-year journey saw offshore wind farms sprout along the coast, sun-soaked solar arrays pop up inland, and the island’s first wave-energy experiments take shape. More than that, it pulled in research institutes and eager developers to test microgrids, green hydrogen production pilots, and electric-mobility schemes. Fast-forward to 2025, and those early experiments have become the springboard for an even bolder thrust toward full carbon neutrality.

Game-Changer: Green Hydrogen Production at Scale

If you thought hydrogen was still tomorrow’s talk, Jeju is making it today’s centerpiece. The island plans to ramp up green hydrogen production fivefold, targeting 60,000 tons a year by 2035. Electrolyzers powered exclusively by wind and solar are already humming, thanks to a 10.9 MW pilot project led by Korea Southern Power and Hyundai Motor Group. That clean fuel is set to power everything—converted turbines, electric buses, freight vehicles, even fuel-cell systems in apartment complexes—stitching together a zero-carbon energy ecosystem.

Power Shift: 70% Renewable Electricity

Today, roughly 20% of Jeju’s electricity comes from clean sources. Ambitious by anyone’s measure, the island is gunning for 70% renewable electricity by 2035. Imagine sleek turbines perched on the skyline, solar panels shimmering in fields, and extra juice funneled straight into electrolyzers and EV chargers. It’s not just about slashing emissions—it also locks Jeju in against the ups and downs of global fuel markets.

Retrofitting for Hydrogen Turbines

Instead of mothballing its existing LNG-fired plants, Jeju is giving them a second life. The province is retrofitting old turbines to burn pure hydrogen, turning them into flexible, zero-emission powerhouses. It’s a crafty move that rescues existing infrastructure, ensures reliable backup power, and keeps the island grid humming smoothly, even when the sun dips or the wind dies down.

EVs That Give Back: Vehicle-to-Grid (V2G)

Jeju’s EV game is already strong—electric cars make up more than 10% of all vehicles, about five times the national average. But here’s the kicker: many of those cars are outfitted with vehicle-to-grid capability. When the grid hits a peak, models like the Kia EV9 can channel power back, smoothing out demand spikes and turning every EV into a rolling battery. It’s a smart way to boost resilience and make the most of renewable power.

Eco-Tourism & Community Benefits

Tourism has long been Jeju’s lifeblood, and now it’s getting a green makeover. Visitors can choose “green stays” at hotels that run on on-site hydrogen fuel cells or solar-plus-battery setups. Electric shuttles zip around national parks, charging hubs pop up in beach towns, and local farms are testing hydrogen-fueled tractors to cut diesel use. It’s sustainability you can see, ride, and taste—while keeping tourist dollars circulating in the local economy.

Smart Grids and Home Fuel Cells

Under the surface lies a high-tech smart grid weaving together wind, solar, green hydrogen production, and EVs. Real-time sensors and automated controls balance supply and demand across neighborhoods, spotting dips and surges before they happen. At the same time, hydrogen fuel cells in apartment buildings quietly generate power and heat, shrinking energy bills and emissions in one fell swoop. It’s about energy independence with zero smoke, zero soot—just the quiet hum of progress.

Policy & Regulation: Setting the Stage

None of this would fly without a solid rulebook. Jeju’s government has rolled out incentives for renewable-energy investors, streamlined permits for hydrogen turbines and microgrids, and introduced feed-in tariffs for vehicle-to-grid services. Zoning laws now favor microgrid installations in rural villages, and public-private partnerships ensure that both risks and rewards are shared. That policy clarity has attracted innovators, investors, and startups eager to join Jeju’s clean-tech revolution.

Global Model & Local Jobs

Jeju’s journey isn’t happening in isolation. The Presidential Committee for Decentralization and Balanced Development has given the island’s strategy a thumbs-up, positioning it as a national testbed for carbon-neutral policies. Meanwhile, the Global Green Growth Institute (GGGI) is packaging Jeju’s playbook so other islands and remote regions can follow suit. And at home, this green transition promises thousands of new jobs—from construction crews to maintenance teams, researchers to eco-tourism guides—while local universities train the next wave of clean-energy pros.

A Glimpse into Tomorrow

Take a stroll through Jeju City, and you’ll see the future unfolding: electric buses pull up beside hydrogen taxis, solar panels pivot to chase the sun, and smart poles adjust on the fly. Digital dashboards track every flicker of energy, making sure nothing goes to waste. It’s living proof that Jeju carbon neutrality 2035 isn’t just talk—it’s happening now. And as the island barrels toward its 2035 target, it’s sending a clear message: when communities, companies, and governments team up, a zero-carbon future is not just possible—it’s downright thrilling.
