State Sen. Joe Markley calls a new surcharge on ratepayers' bills "a sneaky trick played on utility customers," which is why he personally filed a lawsuit challenging its validity.
The surcharge, a tax on electric ratepayers, was approved last year by the governor and lawmakers. The tax adds about $3.50 per month to an average household's electric bill. Connecticut Light & Power customers began paying the additional tax January 1. United Illuminating customers will see the tax appear on their electric bills later this year.
Markley, a Southington Republican, says the tax is illegal. The tax replaces a surcharge that was put in place a decade ago to pay back bonds that were used to reimburse Northeast Utilities for the value of generating plants that the company lost when electric restructuring forced the company out of the generation business. That surcharge expired at the end of 2010, when the money was paid back.
If the tax had not been added, the average CL&P ratepayer would have seen their electric bills decrease by 9 percent or 10 percent.
Markley is getting his day in court, as the case is being heard before the State Supreme Court in Hartford.
"The tax is unfair for two reasons," Markley has said. "It is levied by a state agency, which doesn't have the authority to do so and there are six towns that would be exempt from paying the tax."
The exempt towns are Wallingford, Norwich, Bozrah, Groton, Norwalk and Lebanon.
Boeing 787 More-Electric Architecture replaces pneumatics with bleedless pressurization, VFSG starter-generators, electric brakes, and heated wing anti-ice, leveraging APU, RAT, batteries, and airport ground power for efficient, redundant electrical power distribution.
Key Points
An integrated, bleedless electrical system powering start, pressurization, brakes, and anti-ice via VFSGs, APU and RAT.
✅ VFSGs start engines, then generate 235Vac variable-frequency power
✅ Bleedless pressurization, electric anti-ice improve fuel efficiency
✅ Electric brakes cut hydraulic weight and simplify maintenance
The 787 Dreamliner is different to most commercial aircraft flying the skies today. On the surface it may seem pretty similar to the likes of the 777 and A350, but get under the skin and it’s a whole different aircraft.
When Boeing designed the 787, in order to make it as fuel efficient as possible, it had to completely shake up the way some of the normal aircraft systems operated. Traditionally, systems such as the pressurization, engine start and wing anti-ice were powered by pneumatics. The wheel brakes were powered by the hydraulics. These essential systems required a lot of physical architecture and with that comes weight and maintenance. This got engineers thinking.
What if the brakes didn’t need the hydraulics? What if the engines could be started without the pneumatic system? What if the pressurisation system didn’t need bleed air from the engines? Imagine if all these systems could be powered electrically… so that’s what they did.
Power sources
The 787 uses a lot of electricity. Therefore, to keep up with the demand, it has a number of sources of power, much as grid operators track supply on the GB energy dashboard to balance loads. Depending on whether the aircraft is on the ground with its engines off or in the air with both engines running, different combinations of the power sources are used.
Engine starter/generators
The main source of power comes from four 235Vac variable frequency engine starter/generators (VFSGs). There are two of these in each engine. These function as electrically powered starter motors for the engine start, and once the engine is running, then act as engine driven generators.
The generators in the left engine are designated as L1 and L2, the two in the right engine are R1 and R2. They are connected to their respective engine gearbox to generate electrical power directly proportional to the engine speed. With the engines running, the generators provide electrical power to all the aircraft systems.
APU starter/generators
In the tail of most commercial aircraft sits a small engine, the Auxiliary Power Unit (APU). While this does not provide any power for aircraft propulsion, it does provide electrics for when the engines are not running.
The APU of the 787 has the same generators as each of the engines — two 235Vac VFSGs, designated L and R. They act as starter motors to get the APU going and once running, then act as generators. The power generated is once again directly proportional to the APU speed.
The APU not only provides power to the aircraft on the ground when the engines are switched off, but it can also provide power in flight should there be a problem with one of the engine generators.
Battery power
The aircraft has one main battery and one APU battery. The latter is quite basic, providing power to start the APU and for some of the external aircraft lighting.
The main battery is there to power the aircraft up when everything has been switched off and also in cases of extreme electrical failure in flight, and in the grid context, alternatives such as gravity power storage are being explored for long-duration resilience. It provides power to start the APU, acts as a back-up for the brakes and also feeds the captain’s flight instruments until the Ram Air Turbine deploys.
Ram air turbine (RAT) generator
When you need this, you’re really not having a great day. The RAT is a small propeller which automatically drops out of the underside of the aircraft in the event of a double engine failure (or when all three hydraulics system pressures are low). It can also be deployed manually by pressing a switch in the flight deck.
Once deployed into the airflow, the RAT spins up and turns the RAT generator. This provides enough electrical power to operate the captain’s flight instruments and other essentials items for communication, navigation and flight controls.
External power
Using the APU on the ground for electrics is fine, but they do tend to be quite noisy. Not great for airports wishing to keep their noise footprint down. To enable aircraft to be powered without the APU, most big airports will have a ground power system drawing from national grids, including output from facilities such as Barakah Unit 1 as part of the mix. Large cables from the airport power supply connect 115Vac to the aircraft and allow pilots to shut down the APU. This not only keeps the noise down but also saves on the fuel which the APU would use.
The 787 has three external power inputs — two at the front and one at the rear. The forward system is used to power systems required for ground operations such as lighting, cargo door operation and some cabin systems. If only one forward power source is connected, only very limited functions will be available.
The aft external power is only used when the ground power is required for engine start.
Circuit breakers
Most flight decks you visit will have the back wall covered in circuit breakers — CBs. If there is a problem with a system, the circuit breaker may “pop” to preserve the aircraft electrical system. If a particular system is not working, part of the engineers procedure may require them to pull and “collar” a CB — placing a small ring around the CB to stop it from being pushed back in. However, on the 787 there are no physical circuit breakers. You’ve guessed it, they’re electric.
Within the Multi Function Display screen is the Circuit Breaker Indication and Control (CBIC). From here, engineers and pilots are able to access all the “CBs” which would normally be on the back wall of the flight deck. If an operational procedure requires it, engineers are able to electrically pull and collar a CB giving the same result as a conventional CB.
Not only does this mean that the there are no physical CBs which may need replacing, it also creates space behind the flight deck which can be utilised for the galley area and cabin.
A normal flight
While it’s useful to have all these systems, they are never all used at the same time, and, as the power sector’s COVID-19 mitigation strategies showed, resilience planning matters across operations. Depending on the stage of the flight, different power sources will be used, sometimes in conjunction with others, to supply the required power.
On the ground
When we arrive at the aircraft, more often than not the aircraft is plugged into the external power with the APU off. Electricity is the blood of the 787 and it doesn’t like to be without a good supply constantly pumping through its system, and, as seen in NYC electric rhythms during COVID-19, demand patterns can shift quickly. Ground staff will connect two forward external power sources, as this enables us to operate the maximum number of systems as we prepare the aircraft for departure.
Whilst connected to the external source, there is not enough power to run the air conditioning system. As a result, whilst the APU is off, air conditioning is provided by Preconditioned Air (PCA) units on the ground. These connect to the aircraft by a pipe and pump cool air into the cabin to keep the temperature at a comfortable level.
APU start
As we near departure time, we need to start making some changes to the configuration of the electrical system. Before we can push back , the external power needs to be disconnected — the airports don’t take too kindly to us taking their cables with us — and since that supply ultimately comes from the grid, projects like the Bruce Power upgrade increase available capacity during peaks, but we need to generate our own power before we start the engines so to do this, we use the APU.
The APU, like any engine, takes a little time to start up, around 90 seconds or so. If you remember from before, the external power only supplies 115Vac whereas the two VFSGs in the APU each provide 235Vac. As a result, as soon as the APU is running, it automatically takes over the running of the electrical systems. The ground staff are then clear to disconnect the ground power.
If you read my article on how the 787 is pressurised, you’ll know that it’s powered by the electrical system. As soon as the APU is supplying the electricity, there is enough power to run the aircraft air conditioning. The PCA can then be removed.
Engine start
Once all doors and hatches are closed, external cables and pipes have been removed and the APU is running, we’re ready to push back from the gate and start our engines. Both engines are normally started at the same time, unless the outside air temperature is below 5°C.
On other aircraft types, the engines require high pressure air from the APU to turn the starter in the engine. This requires a lot of power from the APU and is also quite noisy. On the 787, the engine start is entirely electrical.
Power is drawn from the APU and feeds the VFSGs in the engines. If you remember from earlier, these fist act as starter motors. The starter motor starts the turn the turbines in the middle of the engine. These in turn start to turn the forward stages of the engine. Once there is enough airflow through the engine, and the fuel is igniting, there is enough energy to continue running itself.
After start
Once the engine is running, the VFSGs stop acting as starter motors and revert to acting as generators. As these generators are the preferred power source, they automatically take over the running of the electrical systems from the APU, which can then be switched off. The aircraft is now in the desired configuration for flight, with the 4 VFSGs in both engines providing all the power the aircraft needs.
As the aircraft moves away towards the runway, another electrically powered system is used — the brakes. On other aircraft types, the brakes are powered by the hydraulics system. This requires extra pipe work and the associated weight that goes with that. Hydraulically powered brake units can also be time consuming to replace.
By having electric brakes, the 787 is able to reduce the weight of the hydraulics system and it also makes it easier to change brake units. “Plug in and play” brakes are far quicker to change, keeping maintenance costs down and reducing flight delays.
In-flight
Another system which is powered electrically on the 787 is the anti-ice system. As aircraft fly though clouds in cold temperatures, ice can build up along the leading edge of the wing. As this reduces the efficiency of the the wing, we need to get rid of this.
Other aircraft types use hot air from the engines to melt it. On the 787, we have electrically powered pads along the leading edge which heat up to melt the ice.
Not only does this keep more power in the engines, but it also reduces the drag created as the hot air leaves the structure of the wing. A double win for fuel savings.
Once on the ground at the destination, it’s time to start thinking about the electrical configuration again. As we make our way to the gate, we start the APU in preparation for the engine shut down. However, because the engine generators have a high priority than the APU generators, the APU does not automatically take over. Instead, an indication on the EICAS shows APU RUNNING, to inform us that the APU is ready to take the electrical load.
Shutdown
With the park brake set, it’s time to shut the engines down. A final check that the APU is indeed running is made before moving the engine control switches to shut off. Plunging the cabin into darkness isn’t a smooth move. As the engines are shut down, the APU automatically takes over the power supply for the aircraft. Once the ground staff have connected the external power, we then have the option to also shut down the APU.
However, before doing this, we consider the cabin environment. If there is no PCA available and it’s hot outside, without the APU the cabin temperature will rise pretty quickly. In situations like this we’ll wait until all the passengers are off the aircraft until we shut down the APU.
Once on external power, the full flight cycle is complete. The aircraft can now be cleaned and catered, ready for the next crew to take over.
Bottom line
Electricity is a fundamental part of operating the 787. Even when there are no passengers on board, some power is required to keep the systems running, ready for the arrival of the next crew. As we prepare the aircraft for departure and start the engines, various methods of powering the aircraft are used.
The aircraft has six electrical generators, of which only four are used in normal flights. Should one fail, there are back-ups available. Should these back-ups fail, there are back-ups for the back-ups in the form of the battery. Should this back-up fail, there is yet another layer of contingency in the form of the RAT. A highly unlikely event.
The 787 was built around improving efficiency and lowering carbon emissions whilst ensuring unrivalled levels safety, and, in the wider energy landscape, perspectives like nuclear beyond electricity highlight complementary paths to decarbonization — a mission it’s able to achieve on hundreds of flights every single day.
UK Marine Energy and Climate Resilience can counter sea level rise and storm surge with tidal power, subsea turbines, heat pumps, and flood barriers, delivering renewable electricity, stability, and coastal protection for the United Kingdom.
Key Points
Integrated use of tidal power, barriers, and heat pumps to curb sea level rise, manage storms, and green the UK grid.
✅ Tidal bridges and subsea turbines enhance baseload renewables
✅ Integrated barriers cut storm surge and river flood risk
✅ Heat pumps and marine heat networks decarbonize coastal cities
IN concentrating on electrically driven cars, the UK’s new ten-point energy plans, and recent UK net zero policies, ignores the elephant in the room.
It fails to address the forecast six-metre sea level rise from global warming rapidly melting the Greenland ice sheet.
Rising sea levels and storm surge, combined with increasingly heavy rainfall swelling our rivers, threaten not only hundreds of coastal communities but also much unprotected strategic infrastructure, including electricity systems that need greater resilience.
New nuclear power stations proposed in this United Kingdom plan would produce radioactive waste requiring thousands of years to safely decay.
This is hardly the solution for the Green Energy future, or the broader global energy transition, that our overlooked marine energy resource could provide.
Sea defences and barrier design, built and integrated with subsea turbines and heat pumps, can deliver marine-driven heat and power to offset the costs, not only of new Thames Barriers, but also future Severn, Forth and other barrages, while reducing reliance on high-GWP gases such as SF6 in switchgear across the grid.
At the Pentland Firth, existing marine turbine power could be enhanced by turbines deployed from new tidal bridges to provide much of UK’s electricity needs, as nations chart an electricity future that replaces fossil fuels, from its estimated 60 gigawatt capability.
Energy from Bluemull Sound could likewise be harvested and exported or used to enhance development around UK’s new space station at Unst.
The 2021 Climate Change Summit gives Glasgow the platform to secure Scotland’s place in a true green, marine energy future and help build an electric planet for the long term.
We must not waste this opportunity.
THERE is no vaccine for climate change.
It is, of course, wonderful news that such progress is being made in the development of Covid-19 vaccines but there is a risk that, no matter how serious the Covid crisis is, it is distracting attention, political will and resources from the climate crisis, a much longer term and more devastating catastrophe.
They are intertwined. As climate and ecological systems change, vectors and pathogens migrate and disease spreads.
What lessons can be learned from one to apply to the other?
Prevention is better than cure. We need to urgently address the climate crisis, charting a path to net zero electricity by the middle of the century, to help prevent future pandemics.
We are only as safe as the most vulnerable. Covid immunisation will protect the most vulnerable; to protect against the effects of climate change we need to look far more deeply. Global challenges require systemic change.
Neither Covid or climate change respect national borders and, for both, we need to value and trust science and the scientific experts and separate them from political posturing.
BC Hydro SAP Oversight Report assesses B.C. Utilities Commission findings on misleading testimony, governance failures, public funds oversight, IT project risk, compliance gaps, audit controls, ratepayer impacts, and regulatory accountability in major enterprise software decisions.
Key Points
A summary of BCUC findings on BC Hydro's SAP IT project oversight, governance lapses, and regulatory compliance.
✅ BCUC probed testimony, cost overruns, and governance failures
✅ Project split to avoid scrutiny; incomplete records and late corrections
✅ Reforms pledged: stronger business cases, compliance, audit controls
B.C. Hydro misled the province’s independent regulator about an expensive technology program, thereby avoiding scrutiny on how it spent millions of dollars in public money, according to a report by the B.C. Utilities Commission.
The Crown power corporation gave inaccurate testimony to regulators about the software it had chosen, called SAP, for an information technology project that has cost $197 million, said the report.
“The way the SAP decision was made prevented its appropriate scrutiny by B.C. Hydro’s board of directors and the BCUC, reflecting governance risks seen in Manitoba Hydro board changes in other jurisdictions,” the commission found.
“B.C. Hydro’s CEO and CFO and its (audit and risk management board committee) members did not exhibit good business judgment when reviewing and approving the SAP decision without an expenditure approval or business case, highlighting how board upheaval at Hydro One can carry market consequences.”
The report was the result of a complaint made in 2016 by then-opposition NDP MLA Adrian Dix, who alleged B.C. Hydro lied to the regulatory commission to try to get approval for a risky IT project in 2008 that then went over budget and resulted in the firing of Hydro’s chief information officer.
The commission spent two years investigating. Its report outlined how B.C. Hydro split the IT project into smaller components to avoid scrutiny, failed to produce the proper planning document when asked, didn’t disclose cost increases of up to $38 million, reflecting pressures seen at Manitoba Hydro's debt across the sector, gave incomplete testimony and did not quickly correct the record when it realized the mistakes.
“Essentially all of the things I asserted were substantiated, and so I’m pleased,” Dix, who is now minister of health, said on Monday. “I think ratepayers can be pleased with it, because even though it was an elaborate process, it involves hundreds of millions of spending by a public utility and it clearly required oversight.”
The BCUC stopped short of agreeing with Dix’s allegation that the errors were deliberate. Instead it pointed toward a culture at B.C. Hydro of confusion, misunderstanding and fear of dealing with the independent regulatory process.
“Therefore, the panel finds that there was a culture of reticence to inform the BCUC when there was doubt about something, even among individuals that understood or should have understood the role of the BCUC, a pattern that can fuel Hydro One investor concerns in comparable markets,” read the report.
“Because of this doubt and uncertainty among B.C. Hydro staff, the panel finds no evidence to support a finding that the BCUC was intentionally misled. The panel finds B.C. Hydro’s culture of reticence to be inappropriate.”
By law, B.C. Hydro is supposed to get approval by the commission for rate changes and major expenditures. Its officials are often put under oath when providing information.
B.C. Hydro apologized for its conduct in 2016. The Crown corporation said Monday it supports the commission’s findings and has made improvements to management of IT projects, including more rigorous business case analyses.
“We participated fully in the commission’s process and acknowledged throughout the inquiry that we could have performed better during the regulatory hearings in 2008,” said spokesperson Tanya Fish.
“Since then, we have taken steps to ensure we meet the highest standards of openness and transparency during regulatory proceedings, including implementing a (thorough) awareness program to support staff in providing transparent and accurate testimony at all times during a regulatory process.”
The Ministry of Energy, which is responsible for B.C. Hydro, said in a statement it accepts all of the BCUC recommendations and will include the findings as part of a review it is conducting into Hydro’s operations and finances, including its deferred operating costs for context, and regulatory oversight.
Dix, who is now grappling with complex IT project management in his Health Ministry, said the lessons learned by B.C. Hydro and outlined in the report are important.
“I think the report is useful reading on all those scores,” he said. “It’s a case study in what shouldn’t happen in a major IT project.”
BC Hydro Power Pathway accelerates electrification with clean energy investments, new transmission lines, upgraded substations, and renewable projects like wind and solar, strengthening the grid, supporting decarbonization, and creating jobs across British Columbia's growing economy.
Key Points
A $36B, 10-year BC Hydro plan to expand clean power infrastructure, accelerate electrification, and support jobs.
✅ $36B for new lines, substations, dam upgrades, and distribution
✅ Supports 10,500-12,500 jobs per year across B.C.
✅ Adds wind and solar, leveraging hydro to balance renewables
BC Hydro is gearing up for a decade of extensive construction to enhance British Columbia's electrical system, supporting a burgeoning clean economy and community growth while generating new employment opportunities.
Premier David Eby emphasized the necessity of expanding the electrical system for industrial growth, residential needs, and future advancements. He highlighted the role of clean, affordable energy in reducing pollution, securing well-paying jobs, and fostering economic growth.
At the B.C. Natural Resources Forum in Prince George, Premier Eby unveiled a $36-billion investment plan for infrastructure projects in communities and regions and green energy solutions to provide clean, affordable electricity for future generations.
The Power Pathway: Building BC’s Energy Future, BC Hydro’s revised 10-year capital plan, involves nearly $36 billion in investments across the province from 2024-25 to 2033-34. This marks a 50% increase from the previous plan of $24 billion and includes a substantial rise in electrification and emissions-reduction projects (nearly $10 billion, up from $1 billion).
These upcoming construction projects are expected to support approximately 10,500 to 12,500 jobs annually. The plan is set to bolster and sustain BC Hydro’s capital investments as significant projects like Site C are near completion.
The plan addresses the increasing demand for electricity due to population and housing growth, industrial development, such as a major hydrogen project, and the transition from fossil fuels to clean electricity. Key projects include constructing new high-voltage transmission lines from Prince George to Terrace, building or expanding substations in high-growth areas, and upgrading dams and generating facilities for enhanced safety and efficiency.
Minister of Energy, Mines, and Low Carbon Innovation Josie Osborne stated that this plan aims to build a clean energy future and support EV charging expansion while creating construction jobs. With BC Hydro’s capital plan allocating almost $4 billion annually for the next decade, it will drive economic growth and ensure access to clean, affordable electricity.
BC Hydro aims to add new clean, renewable energy sources like wind and solar, while acknowledging power supply challenges that must be managed as capacity grows. B.C.’s hydroelectric dams, functioning as batteries, enable the integration of intermittent renewables into the grid, providing reliable backup.
Chris O’Riley, president and CEO of BC Hydro, said the grid is one of the world’s cleanest. The new $36 billion capital plan encompasses investments in generation assets, large transmission infrastructure, and local distribution networks.
In partnership with BC Hydro, Premier Eby also announced a new streamlined approval process to expedite electrification for high-demand industries and support job creation, complementing measures like the BC Hydro rebate and B.C. Affordability Credit that help households.
Minister of Environment and Climate Change Strategy George Heyman highlighted the importance of rapid electrification in collaboration with the private sector to achieve CleanBC climate goals by 2030, including corridor charging via the BC's Electric Highway, and maintain the competitiveness of B.C. industries. The new process will streamline approvals for industrial electrification projects, enhancing efficiency and funding certainty.
Offshore Wind-to-Hydrogen Integration enables green hydrogen by embedding an electrolyzer in offshore turbines. Siemens Gamesa and Siemens Energy align under H2Mare to decarbonize industry, advance the Paris Agreement, and unlock scalable, off-grid renewable production.
Key Points
A method integrating electrolyzers into offshore wind turbines to generate green hydrogen and reduce carbon emissions.
✅ Integrated electrolyzer at turbine base for off-grid operation
✅ Enables scalable, cost-efficient green hydrogen production
✅ Supports decarbonization targets under Paris Agreement
To reach the Paris Agreement goals, the world will need vast amounts of green hydrogen and, with offshore wind growth accelerating, wind will provide a large portion of the power needed for its production.
Siemens Gamesa and Siemens Energy announced today that they are joining forces combining their ongoing wind-to-hydrogen developments to address one of the major challenges of our decade - decarbonizing the economy to solve the climate crisis.
The companies are contributing with their developments to an innovative solution that fully integrates an electrolyzer into an offshore wind turbine as a single synchronized system to directly produce green hydrogen. The companies intend to provide a full-scale offshore demonstration of the solution by 2025/2026. The German Federal Ministry of Education and Research, reflecting Germany's clean energy progress, announced today that the developments can be implemented as part of the ideas competition 'Hydrogen Republic of Germany'.
'Our more than 30 years of experience and leadership in the offshore wind industry, coupled with Siemens Energy's expertise in electrolyzers, brings together brilliant minds and cutting-edge technologies to address the climate crisis. Our wind turbines play a huge role in the decarbonization of the global energy system, and the potential of wind to hydrogen means that we can do this for hard-to-abate industries too. It makes me very proud that our people are a part of shaping a greener future,' said Andreas Nauen, Siemens Gamesa CEO.
Christian Bruch, CEO of Siemens Energy, explains: 'Together with Siemens Gamesa, we are in a unique position to develop this game changing solution. We are the company that can leverage its highly flexible electrolyzer technology and create and redefine the future of sustainable offshore energy production. With these developments, the potential of regions with abundant offshore wind, such as the UK offshore wind sector, will become accessible for the hydrogen economy. It is a prime example of enabling us to store and transport wind energy, thus reducing the carbon footprint of economy.'
Over a time frame of five years, Siemens Gamesa plans to invest EUR 80 million and Siemens Energy is targeting to invest EUR 40 million in the developments. Siemens Gamesa will adapt its development of the world's most powerful turbine, the SG 14-222 DD offshore wind turbine to integrate an electrolysis system seamlessly into the turbine's operations. By leveraging Siemens Gamesa's intricate knowledge and decades of experience with offshore wind, electric losses are reduced to a minimum, while a modular approach ensures a reliable and efficient operational set-up for a scalable offshore wind-to-hydrogen solution. Siemens Energy will develop a new electrolysis product to not only meet the needs of the harsh maritime offshore environment and be in perfect sync with the wind turbine, but also to create a new competitive benchmark for green hydrogen.
The ultimate fully integrated offshore wind-to-hydrogen solution will produce green hydrogen using an electrolyzer array located at the base of the offshore wind turbine tower, blazing a trail towards offshore hydrogen production. The solution will lower the cost of hydrogen by being able to run off grid, much like solar-powered hydrogen in Dubai showcases for desert environments, opening up more and better wind sites. The companies' developments will serve as a test bed for making large-scale, cost-efficient hydrogen production a reality and will prove the feasibility of reliable, effective implementation of wind turbines in systems for producing hydrogen from renewable energy.
The developments are part of the H2Mare initiative which is a lighthouse project likely to be supported by the German Federal Ministry of Education and Research ideas competition 'Hydrogen Republic of Germany'. The H2mare initiative under the consortium lead of Siemens Energy is a modular project consisting of multiple sub-projects to which more than 30 partners from industry, institutes and academia are contributing. Siemens Energy and Siemens Gamesa will contribute to the H2Mare initiative with their own developments in separate modular building blocks.
About hydrogen and its role in the green energy transition
Currently 80 million tons of hydrogen are produced each year and production is expected to increase by about 20 million tons by 2030. Just 1% of that hydrogen is currently generated from green energy sources. The bulk is obtained from natural gas and coal, emitting 830 million tons of CO2 per year, more than the entire nation of Germany or the global shipping industry. Replacing this current polluting consumption would require 820 GW of wind generating capacity, 26% more than the current global installed wind capacity. Looking further ahead, many studies suggest that by 2050 production will have grown to about 500 million tons, with a significant shift to green hydrogen already signaled by projects like Brazil's green hydrogen plant now underway. The expected growth will require between 1,000 GW and 4,000 GW of renewable capacity by 2050 to meet demand, and in the U.S. initiatives like DOE hydrogen hubs aim to catalyze this build-out, which highlights the vast potential for growth in wind power.
UK Wind and Tidal Power Auction signals strong CfD support for offshore wind, tidal stream projects, investor certainty, and clean electricity, accelerating the net-zero transition, boosting jobs, and strengthening UK energy security and grid integration.
Key Points
