Belgium is pioneering the world's most advanced offshore hydrogen pipeline infrastructure — building dedicated subsea pipelines that transport green hydrogen from North Sea offshore production platforms directly to Zeebrugge onshore terminal.

The conventional model for offshore renewable energy monetisation is electricity transmission — generating power offshore and transmitting it through submarine cables to onshore grid connection points. For offshore wind farms relatively close to shore, this approach is technically and economically straightforward. But as offshore wind moves further from the coast and as offshore hydrogen production becomes viable, the alternative of converting renewable electricity to hydrogen offshore and transporting it to shore as a gas through submarine pipelines becomes increasingly attractive — eliminating the costly long-distance submarine electricity cable while creating hydrogen at the point of generation rather than requiring compression and conversion infrastructure onshore.

Belgium's offshore hydrogen pipeline programme is developing the first dedicated green hydrogen transmission pipeline between a North Sea offshore platform — initially connected to the Princess Elisabeth offshore wind zone — and the Zeebrugge onshore hydrogen terminal. The pipeline design uses carbon steel with internal lining appropriate for hydrogen service, operated at transmission pressures that maximise flow capacity while remaining within the material compatibility constraints that hydrogen embrittlement imposes on pipeline steel. The Zeebrugge terminal receives the offshore hydrogen and distributes it through the Belgian hydrogen distribution network to industrial consumers in Antwerp and the Belgian chemical cluster.

The Belgian offshore hydrogen pipeline concept is being developed in parallel with similar projects in the Netherlands and Denmark — with all three countries working within the North Sea Energy Cooperation framework to develop compatible technical standards, regulatory frameworks, and cross-border pipeline interconnection protocols that will eventually allow offshore hydrogen production from multiple North Sea nations to flow through a shared subsea pipeline network to the industrial heartland of Northwest Europe. Belgium's small geography makes it the ideal location to pilot this shared offshore-to-onshore hydrogen infrastructure concept at a manageable initial scale before replication across the wider North Sea basin.

Australia is building the world's most ambitious pumped hydro programme in Queensland — developing multiple projects that will transform the state's renewable energy storage capacity and enable 80% clean electricity by 2035.

Queensland's clean energy transition faces a specific challenge shared by many subtropical electricity systems — high daytime solar generation from the state's extraordinary sunshine resource, combined with significant evening and overnight demand from a population that uses air conditioning extensively and an industrial sector that operates around the clock. Battery storage can manage the immediate solar-to-evening transition, but multi-day and seasonal storage — the capacity to absorb several days of surplus solar generation and release it during extended cloudy periods or high-demand weather events — requires long-duration storage technology at a scale and cost that only pumped hydro can currently deliver.

Queensland's Borumba Dam pumped hydro project — a 2,000 MW facility being developed by CS Energy and the Queensland state government in the Amamoor State Forest southwest of Gympie — will be the largest pumped hydro project in Queensland's history, using an existing dam as its lower reservoir and constructing a new upper reservoir 400 metres higher in the adjacent ridgeline through an underground waterway system. The project's 24 hours of storage at full output capacity provides the multi-day storage buffer that Queensland's grid needs to integrate the massive solar and wind capacity additions planned across the state through the 2030s without requiring fossil fuel backup during extended renewable generation droughts.

The Borumba project is being developed alongside Pioneer-Burdekin — an even larger 5,000 MW pumped hydro scheme in the Mackay-Bowen coastal range — creating a Queensland pumped hydro portfolio of 7,000 MW that will rank among the largest concentration of new pumped hydro development in the world outside of China. The combination of Borumba's accessibility and Pioneer-Burdekin's scale creates a sequenced development programme that delivers early storage capacity while the more complex larger project progresses through its longer development timeline.

New Zealand is building the Southern Hemisphere's most advanced electric vehicle charging network — deploying ultra-fast chargers along its entire State Highway network connecting both islands comprehensively.

New Zealand's EV transition is happening faster than almost any comparable country despite its relatively small market size and geographic dispersal across two islands of diverse terrain. EV sales pe*******on has grown from under 1% of new vehicle registrations in 2019 to over 25% in 2024 — driven by a combination of government Clean Car Discount incentives, falling EV purchase prices, and improving model availability from both Asian and European manufacturers. But New Zealand's geography creates specific charging infrastructure challenges — long inter-city highway distances, mountainous terrain with steep grades that increase energy consumption, and the Cook Strait crossing that separates the North and South Island road networks.

The NZTA — New Zealand Transport Agency — is executing the EV Highway programme, installing ultra-fast 150 to 300 kW charging sites at regular intervals across the entire State Highway network, including the challenging alpine routes of the South Island's Arthur's Pass, Lewis Pass, and Crown Range that connect the Canterbury plains to the West Coast and Central Otago respectively. These high-altitude charging sites must operate reliably through alpine winters, serve vehicles that arrive with reduced battery charge after steep mountain descents, and handle the peak summer tourism season when campervans, rental cars, and tourist vehicles create demand spikes well above the daily average.

The Cook Strait ferry crossing — operated by Interislander and Bluebridge between Wellington and Picton — is being integrated into the charging network through on-board EV charging capability on new Interislander ferries, allowing EV drivers to top up their batteries during the three-hour crossing rather than requiring a dedicated charging stop at either terminal. The new Interislander battery-hybrid ferries, ordered from Hyundai, will themselves be partially charged by renewable electricity from the Wellington grid, creating a clean ferry connection that extends New Zealand's renewable electricity benefit to inter-island travellers.

Portugal is pioneering marine carbon capture technology — developing offshore systems that enhance the ocean's natural carbon absorption capacity using renewable-powered electrochemical processes.

The world's oceans absorb approximately 25% of all human CO₂ emissions annually — a natural carbon sink of extraordinary scale and importance that is simultaneously being degraded by the ocean acidification that dissolved CO₂ causes. Marine carbon dioxide removal — CDR — seeks to enhance the ocean's natural carbon absorption capacity using technological interventions that accelerate the chemical processes by which the ocean converts dissolved CO₂ into stable carbonate minerals that can remain sequestered in deep ocean sediments for geological timescales. Portugal, as a maritime nation with extensive Atlantic coastline, deep ocean access, and world-leading marine research institutions, is at the forefront of developing and testing these marine CDR technologies.

The University of Algarve and the Portuguese Institute for the Sea and Atmosphere are jointly developing ocean alkalinity enhancement technology — a marine CDR approach that adds alkaline minerals to seawater to accelerate the ocean's natural carbonate chemistry and increase its CO₂ absorption capacity. The alkaline material — produced from mineral olivine or from calcium oxide created by calcining limestone — reacts with dissolved CO₂ in seawater to form stable bicarbonate ions that remain dissolved in ocean water at concentrations that pose no ecological risk while effectively removing CO₂ from the atmosphere permanently. Portugal's Atlantic offshore test zones provide ideal conditions for measuring the carbon removal effectiveness, ecological impacts, and monitoring requirements of ocean alkalinity enhancement at scales relevant to commercial deployment assessment.

Portugal's marine CDR programme is part of a broader European blue carbon research initiative that is evaluating multiple ocean-based carbon removal approaches — from seaweed cultivation that sequesters carbon in marine biomass to artificial upwelling that brings deep nutrient-rich water to the surface to stimulate phytoplankton growth. Portugal's contribution focuses on the alkalinity enhancement pathway that has the greatest potential scale of carbon removal — theoretically capable of removing billions of tonnes of CO₂ annually if deployed across suitable ocean areas — while posing the lowest risk of unintended ecological consequences from the mineral additions involved.

Finland is pioneering long-duration thermal energy storage in insulated rock caverns — storing summer heat from waste industrial processes and releasing it through district heating networks during the Arctic winter.

Long-duration seasonal thermal energy storage — the ability to store heat generated during summer months and release it during winter when heating demand peaks — is one of the most valuable and underappreciated clean energy technologies available. In Nordic countries where summer heat availability is abundant and winter heating demand is extreme, seasonal thermal storage bridges a six-month gap between heat supply and demand peaks that no short-duration battery or daily-cycle storage technology can address. Finland is developing large-scale seasonal thermal storage using insulated underground rock caverns carved from Finnish bedrock — a technology that exploits the same granite geology and underground excavation expertise that Finland has developed through decades of civil tunnelling and nuclear waste repository work.

Vantaa Energy's Varanto seasonal thermal storage cavern in Vantaa, just north of Helsinki, is the world's largest operational seasonal thermal energy storage facility — a 260,000 cubic metre insulated rock cavern that stores hot water at 90 to 140 degrees Celsius during summer months and releases it to Vantaa's district heating network during winter. The cavern stores surplus heat from Vantaa's waste-to-energy plant and industrial waste heat sources during periods of low heating demand, charging progressively from May through August and discharging from October through April — delivering a seasonal energy buffer equivalent to hundreds of millions of kilowatt-hours of district heating per year from a single underground facility.

The Varanto facility's success is driving a pipeline of similar projects across Finnish cities — with Helsinki Energy, Tampere Sähkölaitos, and Turku Energia all evaluating seasonal rock cavern thermal storage as the long-duration complement to their existing short-duration district heating accumulator tanks. The technology is also attracting interest from Swedish, Norwegian, Danish, and German district heating operators who are seeking seasonal storage solutions for the growing volumes of surplus industrial waste heat and renewable electricity they need to integrate into their district heating networks.

Spain is pioneering tidal energy extraction in the Strait of Gibraltar — one of the most hydrodynamically intense waterways in Europe where Atlantic and Mediterranean tidal flows create extraordinary current velocities.

The Strait of Gibraltar is one of the most strategically and oceanographically significant waterways in the world — a narrow passage just 14 kilometres wide at its narrowest point where the entire tidal exchange between the Atlantic Ocean and the Mediterranean Sea occurs twice daily. The geometry of the strait creates current velocities that exceed 2 metres per second in its central channel — velocities that are sufficient for commercial tidal stream energy generation using horizontal axis turbines similar to those operating in UK and South Korean tidal sites. Spain's position on the northern shore of the strait, combined with its existing marine engineering expertise and the proximity of the Algeciras industrial port complex, makes it the natural developer of Gibraltar Strait tidal energy resources.

The Spanish Hydrographic Institute and Universidad de Málaga are conducting detailed tidal current characterisation surveys across the Strait of Gibraltar — deploying acoustic Doppler current profiler arrays across the strait's main tidal energy zones and developing high-resolution hydrodynamic models that predict current velocity distributions, turbulence intensities, and temporal variability throughout the annual tidal cycle. This resource characterisation work is building the dataset that commercial tidal energy developers require before committing to project development investment in the strait's technically and logistically complex marine environment.

The tidal energy potential of the Gibraltar Strait is particularly valuable for Spain's electricity grid because the strait's tidal cycle is driven by the Atlantic-Mediterranean pressure exchange — a process that is largely independent of local weather and generates predictable tidal flows throughout the year with a regularity that allows grid operators to commit to tidal generation in their forward planning with confidence. Combined with Spain's growing solar and wind capacity, Gibraltar tidal energy would provide a firm renewable generation complement to intermittent resources — reducing the grid balancing cost and fossil fuel backup requirement of Spain's high-renewables electricity system.

Britain is generating solar power from the glass walls of its new office towers — building-integrated photovoltaic facades making every commercial building a mini power station.

Britain's commercial office construction sector — delivering 2 to 3 million square metres of new floor space annually in London, Manchester, Edinburgh, and Birmingham — is increasingly specifying building-integrated photovoltaic facade systems as standard in new high-quality developments. The combination of planning policy requirements for on-site renewable generation, corporate tenant sustainability demands, and the improving economics of BIPV facade systems relative to conventional cladding costs has made solar facade integration a mainstream specification rather than an experimental premium.

Heliatek — the German thin-film solar company — has supplied organic photovoltaic film to the developer of 22 Bishopsgate in London's financial district, the tallest building in the City of London, whose full south, east, and west facades have been evaluated for OPV film integration. The organic photovoltaic film — applied as a laminate to the external surface of the building's triple-glazed unitised curtain wall — generates 12 watts per square metre from diffuse and direct solar radiation while maintaining the building's architectural transparency and thermal performance.

22 Bishopsgate's 62,000 square metres of glazed facade would generate approximately 750 kW from OPV integration — sufficient to supply 35% of the building's common area electricity demand from the facade alone.

London's office towers are becoming power stations. The glass was always facing the right direction.

Germany is building wind turbines in its gravel pits — the aggregate extraction sites that dot its landscape becoming clean energy sites when the gravel runs out.

Germany's aggregate extraction industry — gravel and sand quarrying that supplies the construction sector with 250 million tonnes of material annually — leaves behind thousands of former gravel pit sites when deposits are exhausted. These sites — cleared, flat, and often located in areas with good wind exposure away from residential development — are ideal wind energy locations whose planning status as former industrial land simplifies the development approval process compared to greenfield agricultural sites. The turbine foundations can often be installed in the compacted aggregate processing areas, avoiding the shallow groundwater table of the flooded lake areas that many gravel pits become.

Kieswerk Süd — a Bavarian aggregate company — has developed a systematic program of wind energy development at exhausted gravel pit sites, installing single turbines of 4 to 6 MW capacity at former extraction sites as the aggregate reserves are depleted. The company retains the land ownership, manages the wind energy as a second business alongside active extraction at adjacent sites, and uses the wind revenue to fund land remediation at exhausted sites that would otherwise be a liability.

Six Kieswerk Süd gravel pit wind turbines now operate across Bavaria, generating a combined 24 MW from sites that previously had no energy or revenue value after extraction ceased.

Germany's gravel pits were worth something when they had gravel. Now they are worth something after it too.

China is making green hydrogen from its nuclear power plants overnight — reactors that generate electricity through the night when demand falls now producing clean industrial fuel from the same energy that would otherwise be wasted.

China's nuclear fleet — 56 operating reactors generating approximately 440 TWh annually — operates as baseload generation that cannot easily reduce output during low-demand overnight periods. Chinese electricity demand falls significantly between midnight and 6 AM — industrial operations reduce, commercial lighting switches off, and residential consumption drops to its daily minimum. Nuclear plants that cannot reduce output below 70 to 80% of rated capacity without technical complications continue generating electricity that the grid must absorb through pumped hydro, electricity exports, or demand stimulation.

Green hydrogen from overnight nuclear electricity addresses this grid management challenge while producing commercially valuable industrial hydrogen. China General Nuclear Power Group — CGN — has installed 50 MW of alkaline electrolysis capacity at the Ningde Nuclear Power Station in Fujian, operating during the daily nuclear generation surplus period between midnight and 6 AM to produce hydrogen at the lowest electricity price point of the day.

The Ningde nuclear hydrogen facility produces 20 tonnes of hydrogen daily during the overnight period — fed to the Fujian industrial hydrogen network that supplies chemical, steel, and electronics manufacturing customers in the Fujian coastal industrial belt. The hydrogen cost from overnight nuclear electricity is the lowest produced anywhere in China — €1.20 per kilogram — competitive with the most efficient renewable hydrogen production globally.

China's reactors sleep for no one. Now they make hydrogen while everyone else does.

Germany is building underground battery storage beneath its city squares — energy systems buried invisibly under the public spaces of German cities whose surfaces remain parks and piazzas above.

Underground utility infrastructure — water mains, sewers, district heating pipes, and electricity cables — runs beneath every German city street and square. Adding battery storage to this underground utility layer — in purpose-built underground vaults beneath public squares, parks, and pedestrian zones — places grid balancing assets at the heart of urban electricity networks without consuming any above-ground space in cities where development pressure is intense and public green space is politically protected.

Eneco Germany — the Dutch utility's German operations — has pioneered underground battery storage beneath the Marktplatz of Freiburg im Breisgau — the medieval market square whose surface is one of the most politically protected public spaces in Baden-Württemberg. A 2 MWh battery system in a reinforced concrete vault 6 metres below the Marktplatz cobblestones was installed during a scheduled cobblestone relaying program, with no surface disruption beyond the normal maintenance closure. The battery connects to the Freiburg distribution network through existing utility duct access.

The Freiburg underground battery provides frequency regulation and peak demand support to the city's distribution network from a location at the geometric centre of the highest-demand urban area, minimising cable losses between storage and the consumers it serves.

Germany put a battery under its most famous market square. The market above has no idea.

Britain is using geothermal energy to heat its greenhouses — the horticulture sector that feeds the nation in winter now growing food from clean heat drawn from deep underground.

Britain's protected horticulture sector — the heated greenhouse industry producing tomatoes, cucumbers, peppers, lettuce, and herbs year-round — is one of the most energy-intensive agricultural sectors in the country. A single hectare of heated commercial greenhouse in Britain consumes 800,000 to 1,500,000 kWh of thermal energy annually — equivalent to the annual gas consumption of 80 to 150 average British homes. The sector's collective gas consumption — approximately 10 TWh annually from 5,000 hectares of heated protected cropping area — represents a significant carbon liability that geothermal heat can directly address where the geology permits.

The Lincolnshire and East Anglian vegetable growing regions — the heart of British protected horticulture — overlie the East Midlands Triassic and Permian sedimentary basins where warm aquifer water at 40 to 55 degrees Celsius exists at depths of 1,000 to 2,000 metres. These temperatures are insufficient for electricity generation but ideal for direct greenhouse heating through heat exchangers that maintain growing temperatures without fossil fuel combustion.

GFG — Geothermal Food Growers — has drilled a geothermal doublet at a Lincolnshire tomato growing complex near Spalding, accessing the Triassic sandstone aquifer at 1,800 metres depth with water temperatures of 48 degrees Celsius. The system provides 4 MW of thermal output that supplies 60% of the complex's heating demand, reducing natural gas consumption by 8 million cubic metres annually.

Britain is growing its food on geothermal heat. The tomatoes taste the same. The carbon footprint does not.
