Top 10 Geothermal Problems: Why a 24/7 Resource Still Struggles to Scale Image credit : Fida, C.E.O Geosilica... This is what scaling looks like downhole in geothermal pipes Intelligence; Strategy for the Geothermal Decade Geothermal energy is often presented as the clean firm resource that can support a renewable electricity system around the clock. It does not depend on sunshine, it can operate through calm weather, and it can provide heat and power for decades. Kenya already relies heavily on geothermal generation , Iceland uses geothermal heat across its economy, and next generation developers are now signing large power contracts with technology companies seeking reliable carbon free electricity. Yet the global geothermal sector remains small compared with solar and wind, with installed electricity capacity still near 16 GW. That gap is not caused by one obstacle. It is produced by a chain of interlocking problems involving geology, drilling, finance, permitting, public acce...
Unlocking Earth's Fury: Star Energy's Geothermal Breakthrough in Hamiding
Welcome back to Alphaxioms Geothermal News, your go-to source for the latest in renewable energy innovations from around the globe. As we dive into 2026, the world is buzzing with the urgent need for sustainable power sources, and Indonesia is leading the charge with its vast geothermal treasures. Today, we're spotlighting a game-changing development from PT Barito Renewables Energy Tbk (BREN) that's not just about megawatts—it's about reshaping our planet's energy future. Imagine tapping into the raw power simmering beneath volcanic peaks, turning steam into electricity that powers homes, industries, and dreams. That's exactly what's unfolding at Gunung Hamiding in North Halmahera, where Star Energy has just wrapped up an exploration phase revealing a whopping 55-60 MW of geothermal potential. Buckle up as we unpack this electrifying story in detail.
The Dawn of a New Era in Halmahera
Picture this: a remote, rugged landscape in Indonesia's eastern archipelago, where ancient volcanoes hold secrets of untapped energy. PT Star Energy Geothermal Indonesia, a key subsidiary of BREN, has been on a mission here since receiving the green light from the government back in 2013 via Ministerial Decree No. 0459K/30/MEM/2013. Their target? Gunung Hamiding, a geothermal prospect in North Halmahera Regency that's now confirmed to pack a punch of up to 60 MW—enough to light up thousands of households and fuel local economies.
The exploration wrapped up on January 14, 2026, marking a pivotal milestone in BREN's phased approach to development. This isn't some hasty dig; it's a meticulous process aligned with the Ministry of Energy and Mineral Resources (ESDM) guidelines. Teams conducted comprehensive surveys,geological, geochemical, geophysical, and geotechnical,followed by civil engineering feats and exploratory drilling. It's like piecing together a giant underground puzzle, where every data point reveals more about the hot reservoirs lurking below.
Hendra Soetjipto Tan, President Director of Barito Renewables, couldn't hide his enthusiasm. In a statement released on January 13, he called it a "significant milestone" in their stepwise journey toward an initial 50 MW geothermal power plant in Halmahera. "This achievement reflects our commitment to providing clean, reliable energy while supporting Indonesia's transition to a sustainable energy future," Tan said. His words echo the broader vision: turning volcanic heat into a lifeline for a nation hungry for green power.
But let's get into the nuts and bolts. To make this happen, Star Energy didn't just poke around—they built an infrastructure backbone. They extended existing access roads by 7.7 kilometers, carved out 13.8 kilometers of brand-new paths through challenging terrain, constructed three sturdy bridges, and set up a dedicated well pad. These aren't mere conveniences; they're essential for safe, efficient operations in a region where Mother Nature doesn't always play nice. Imagine crews navigating misty mountains, drilling into the earth while ensuring minimal disruption to the ecosystem. It's engineering heroism at its finest.
Beyond Power: Environmental and Social Ripples
Geothermal energy isn't just about flipping switches,it's a holistic revolution. At Hamiding, the project promises to slash reliance on fossil fuels, curbing greenhouse gas emissions that choke our atmosphere. In a world grappling with climate chaos, this is a breath of fresh air (literally). Indonesia, with its Ring of Fire location, sits on a goldmine of geothermal resources, and developments like this are key to unlocking it without the carbon footprint of coal or oil.
On the social front, Star Energy is walking the talk. They're collaborating with local communities and stakeholders in North Halmahera to create jobs, upgrade infrastructure, and roll out social programs. Think about it: new roads mean better access to markets and healthcare; employment opportunities empower families; and community initiatives foster long-term harmony. This isn't corporate lip service—it's real impact. As Tan's team pushes forward, they're ensuring that the benefits flow beyond the power grid, nurturing a symbiotic relationship between industry and locals.
Zooming out, this fits into Indonesia's grand geothermal narrative. According to ESDM data, the country's installed geothermal capacity stands at 2,744 MW, making it the world's second-largest after the United States' 3,937 MW. Yet, that's just scratching the surface—only about 10% of the nation's immense potential has been tapped. Minister Bahlil Lahadalia recently highlighted this disparity: "Geothermal is one of our renewable energy sources, and Indonesia has the largest reserves in the world. But we've only managed around 10% so far, meaning 90% is still out there." His words are a rallying cry for acceleration.
Indonesia's Geothermal Giant Awakens
Indonesia's geothermal story is one of epic proportions. Straddling tectonic plates, the archipelago boasts over 400 volcanoes, many harboring geothermal hotspots. With reserves estimated at a staggering 24,000 MW or more, it's no wonder experts call it the "sleeping giant" of renewables. But awakening this giant requires vision, investment, and policy muscle.
Enter the government's Rencana Usaha Penyediaan Tenaga Listrik (RUPTL) for 2025-2034, a blueprint that's supercharging the sector. Plans include building 48,000 kilometers of transmission lines to connect remote geothermal sites like Hamiding to the national grid. This infrastructure push isn't just wires and poles,it's the veins that will pump clean energy across islands, from Sumatra to Papua. By integrating renewables, Indonesia aims to hit its net-zero emissions targets while bolstering energy security amid global volatility.
Compare this to global peers: The U.S. leads, but Indonesia's potential dwarfs it. Countries like Iceland and New Zealand have long harnessed geothermal for heating and power, proving its reliability,it's baseload energy, running 24/7 unlike intermittent solar or wind. For Indonesia, scaling up could mean energy independence, reduced imports, and a starring role in the global green transition. Projects like Hamiding are the building blocks, demonstrating that with the right expertise (shoutout to Star Energy's track record), barriers like remote locations and high upfront costs can be overcome.
Challenges remain, of course. Geothermal development demands hefty initial investments for exploration and drilling, and regulatory hurdles can slow progress. Environmental concerns, such as land use and water impacts, must be managed meticulously. But successes like this one show the path forward: transparent, community-driven, and tech-savvy approaches that minimize risks and maximize gains.
Looking Ahead: A Steamy Future
As we wrap up this deep dive, it's clear that Star Energy's Hamiding breakthrough is more than a corporate win,it's a beacon for sustainable development. With 55-60 MW on the horizon and plans for a 50 MW plant, BREN is positioning Indonesia as a geothermal powerhouse. This aligns perfectly with national goals, where Minister Lahadalia's 90% untapped potential beckons like buried treasure.
For investors and eco-enthusiasts alike, keep an eye on BREN. Their commitment to clean energy isn't just talk; it's action, from Halmahera's hills to the boardrooms of Jakarta. As global demands for renewables soar—think electric vehicles, data centers, and climate accords,Indonesia's geothermal surge could power a brighter tomorrow.
