Comparing A new study titled "Carrying the Energy Future: Comparing Hydrogen and Electricity for Transmission, Storage and Transportation" by the Seattle based Institute for Lifecycle Environmental Assessment (ILEA,) evaluated the energy penalties incurred in using hydrogen to transmit energy as compared to those incurred using electricity.

The report's main premise is that since hydrogen is not an energy source but an energy carrier its economic and environmental qualities should be compared to those of electricity, the only other commonplace energy carrier. It therefore compares the actual energy available when hydrogen and electricity carriers are employed and finds that electricity delivers substantially greater end use energy, concluding that "electricity offers more energy efficient options that might preclude mass-scale emergence of hydrogen technologies."

To illustrate the relative efficiencies of the two energy transmission methods, the study evaluated transmission of 4,000 megawatts of wind energy generated in the Great Plains wind fields to Chicago. Carrying the energy generated from remote renewable sources - solar, wind, etc. - to distant markets as hydrogen, requires that the electricity generated in wind turbines or solar panels be used to break water molecules into hydrogen and oxygen in a process called electrolysis. At the point of use (eg. on board a fuel cell vehicle,) hydrogen must again be converted into electricity.

Once energy penalties are taken into account, the above process leaves only 45-55% of the original energy compared to 92% if transmitted as electricity. Electrical transmission provides roughly twice the end use energy.

Storage is no less of a problem. Hydrogen is envisaged as a medium to store energy generated by renewables, making power available on demand. However the same aforementioned energy penalties apply while other energy storage technologies deliver comparatively more energy. Hydrogen storage returns around 47% of original energy, while advanced batteries return 75-85%.

According to the report, using electricity to charge electric vehicles (EVs) provides twice the miles per kilowatt hour than employing electricity to make hydrogen fuel. Lithium ion batteries developed for portable electronics can store electricity at an energy density about six times greater than conventional lead acid batteries and in the future could go nearly 250 miles between charges.

The report's authors Patrick Mazza and Roel Hammerschlag are particularly enthusiastic about plug-in hybrid electric vehicles (PHEV). Hybrid cars like Toyota Prius are already on the road today by the thousands. Their batteries are kept charged by power generated onboard. True to their name, plug in HEVs are hybrids that can be plugged in and draw charge from the power grid. Since they also have a fuel tank, PHEVs can take advantage of EV efficiencies without range and charge time limitations.

With a nickel metal hydride battery, similar to the one used in hybrids today, a PHEV could go up to 60 miles on grid power before the engine seamlessly kicks in. Considering the fact that half the cars on the road in the U.S. are driven fewer than 20 miles per day, most drivers, assuming they recharge their cars at night, will seldom have to dip into their gasoline tank. As a result, PHEV could reduce fuel consumption 85% over a comparable conventional car. That means that a plug-in hybrid SUV would consume less gasoline than a "regular" compact car, without a performance penalty. If such car runs on alcohol fuels instead of gasoline, oil consumption could be reduced even further.

The study distinguishes between hydrogen and fuel cells. While a hydrogen fuel system is hindered by multiple inefficiencies, fuel cells can form an important part of highly efficient systems that convert alcohol fuels to electricity. Fuel cells can operate as stationary electrical generators, potentially at significantly higher efficiencies than central power stations or other distributed generators. Emergence of a substantial fuel cell market is in no way conditioned on mass application in vehicles or development of a hydrogen network.

The study recommends that hydrogen and electricity advocates focus on complementary development that can support both pathways. This includes rapid expansion of renewables, improvement in hybrid vehicle technology, vehicle-to-grid applications that employ parked vehicles as grid energy storage, and development of biomass supplies from which liquid vehicle fuels and hydrogen can be made.

Ontario Teachers' Plan Acquires Brazilian Electricity Transmission Firm Evoltz

Ontario Teachers' Evoltz Acquisition expands electricity transmission in Brazil, adding seven grid lines across ten states, aligning infrastructure strategy with inflation-linked cash flows, renewable energy integration, Latin America and net-zero objectives pending regulatory approvals.

 

Key Points

A 100% purchase of Brazil's Evoltz, adding seven grid lines and delivering stable, inflation-linked cash flows.

✅ 100% stake in Evoltz with seven transmission lines

✅ Aligns with net-zero and renewable energy strategy

✅ Inflation-linked, core infrastructure cash flows in Brazil

 

The Ontario Teachers’ Pension Plan has acquired Evoltz Participações, an electricity transmission firm in Brazil, from US asset manager TPG. 

The retirement system took a 100% stake in the energy firm, Ontario Teachers’ said Monday. The acquisition has netted the pension fund seven electricity transmission lines that service consumers and businesses across 10 states in Brazil, amid dynamics similar to electricity rate reductions for businesses seen in Ontario. The firm was founded by TPG just three years ago. 

“Our strategy focuses on allocating significant capital to high-quality core infrastructure assets with lower risks and stable inflation-linked cash flows,” Dale Burgess, senior managing director of infrastructure and natural resources at Ontario Teachers, said in a statement. “Electricity transmission businesses are particularly attractive given their importance in facilitating a transition to a low-carbon economy.” 

The pension fund has invested in other electricity distribution companies recently. In March, Ontario Teachers’ took a 40% stake in Finland’s Caruna, and agreed to acquire a 25% stake in SSEN Transmission in the UK grid. For more than a decade, it has maintained a 50% stake in Chile-based transmission firm Saesa. 

The investment into Evoltz demonstrates Ontario Teachers’ growing portfolio in Brazil and Latin America, while activity in Ontario such as the Peterborough Distribution sale reflects ongoing utility consolidation. In 2016, the firm, with the Canada Pension Plan Investment Board (CPPIB), invested in toll roads in Mexico. They took a 49% stake with Latin American infrastructure group IDEAL. 

Evoltz, which delivers renewable energy, will also help decarbonize the pension fund’s portfolio. In January, the fund pledged to reach net-zero carbon emissions by 2050. Last year, Ontario Teachers’ issued its first green bond offering. The $890 million 10-year bond will help the retirement system fund sustainable investments aligned with policy measures like Ontario's subsidized hydro plan during COVID-19. 

However, Ontario Teachers’ has also received criticism for its investment into parts of Abu Dhabi’s gas pipeline network, and investor concerns about Hydro One highlight sector uncertainties. Last summer, it joined other institutional investors in investing $10.1 billion for a 49% stake. 

As of December, Ontario Teachers’ reached a portfolio with C$221.2 billion (US$182.5 billion) in assets. Since 1990, the fund has maintained a 9.6% annualized return. Last year, it missed its benchmark with an 8.6% return, with examples such as Hydro One shares fall after shake-up underscoring market volatility.

The pension fund expects the deal will close later this fall, pending closing conditions and regulatory approvals, including decisions such as the OEB combined T&D rates ruling that shape utility economics.

New rules give British households right to sell solar power back to energy firms

UK Smart Export Guarantee enables households to sell surplus solar energy to suppliers, with dynamic export tariffs, grid payments, and battery-friendly incentives, boosting local renewable generation, microgeneration uptake, and decarbonisation across Britain.

 

Key Points

UK Smart Export Guarantee pays homes for exporting surplus solar power to the grid via supplier tariffs.

✅ Suppliers must pay households for exported kWh.

✅ Dynamic tariffs incentivize daytime solar generation.

✅ Batteries boost self-consumption and grid flexibility.

 

Britain’s biggest energy companies will have to buy renewable energy from their own customers through community-generated green electricity models under new laws to be introduced this week.

Homeowners who install new rooftop solar panels from 1 January 2020 will be able to lower their bills as many seek to cut soaring bills by selling the energy they do not need to their supplier.

A record was set at noon on a Friday in May 2017, when solar energy supplied around a quarter of the UK’s electricity, and a recent award that adds 10 GW of renewables indicates further growth.

However, solar panel owners are not always at home on sunny days to reap the benefit. The new rules will allow them to make money if they generate electricity for the grid.

Some 800,000 householders with solar panels already benefit from payments under a previous scheme. However, the subsidies were controversially scrapped by the government in April, with similar reduced credits for solar owners seen in other regions, causing the number of new installations to fall by 94% in May from the month before.

Labour accused the government last week of “actively dismantling” the solar industry. The sector will still struggle this summer as the change does not come in for another seven months, so homeowners have no incentive to buy panels this year.

Chris Skidmore, the minister for energy and clean growth, said the government wanted to increase the number of small-scale generators without adding the cost of subsidies to energy bills. “The future of energy is local and the new smart export guarantee will ensure households that choose to become green energy generators will be guaranteed a payment for electricity supplied to the grid,” he said. The government also hopes to encourage homes with solar panels to install batteries to help manage excess solar power on networks.

Greg Jackson, the founder of Octopus Energy, said: “These smart export tariffs are game-changing when it comes to harnessing the power of citizens to tackle climate change”.

A few suppliers, including Octopus, already offer to buy solar power from their customers, often setting terms for how solar owners are paid that reflect market conditions.

“They mean homes and businesses can be paid for producing clean electricity just like traditional generators, replacing old dirty power stations and pumping more renewable energy into the grid. This will help bring down prices for everyone as we use cheaper power generated locally by our neighbours,” Jackson said.

Léonie Greene, a director at the Solar Trade Association, said it was “vital” that even “very small players” were paid a fair price. “We will be watching the market like a hawk to see if competitive offers come forward that properly value the power that smart solar homes can contribute to the decarbonising electricity grid,” she said.

Nissan accepting electricity from EVs as payment for parking

Nissan V2G Parking lets EV drivers pay with electricity via bidirectional charging at the Yokohama Nissan Pavilion, showcasing vehicle-to-grid, smart energy trading, and integrated mobility experiences like Ariya rides and Formula E simulators.

 

Key Points

A program where EV owners use V2G to pay for parking by discharging power at Nissan's Yokohama Pavilion.

✅ Pay for parking with EV energy via V2G

✅ Powered by Nissan LEAFs and solar at the Pavilion

✅ Showcases Ariya, Formula E, ProPILOT, and I2V tech

 

Nissan is letting customers pay for parking with electricity by discharging power from their electric car’s battery pack, a concept similar to how EV owners sell electricity back to the grid in other programs. In what the company claims to be a global first, owner of electric cars can trade energy for a parking space at Nissan Pavilion exhibition space in Yokohama, Japan, echoing how parked EVs earn from Europe's grids in comparable schemes.

The venue that showcases Nissan's future technologies, opened its doors to public on August 1 and will remain so through October 23, underscoring how stored EV energy can power buildings in broader applications. “(It) is a place where customers can see, feel, and be inspired by (the company's) near-future vision for society and mobility," says CEO Makoto Uchida. “As the world shifts to electric mobility, EVs will be integrated into society in ways that go beyond just transportation."

Apart from the innovate parking experience, people visiting the pavilion can also virtually experience the thrill of Formula E electric street racing or go for a ride in the all-new Ariya electric crossover, similar to demos at the Everything Electric show in Vancouver. Other experiences include ProPILOT advanced driver assistance system as well as Nissan’s Invisible-to-Visible (I2V) technology, which combines information from the real and virtual worlds to assist drivers, themes also explored at an EV education centre in Toronto for public outreach.

A mobility hub in front of the Pavilion offers a variety of services including EV car-sharing. The Pavilion also operates a cafe operated on power supplied by Nissan LEAF electric cars and solar energy, showcasing vehicle-to-building charging benefits on site.

As part of its Nissan NEXT transformation plan, the company plans to expand its global lineup of EVs and aims to sell more than 1 million electrified vehicles a year by the end of fiscal 2023, aligning with the American EV boom and the challenge of scaling charging infrastructure.

National Energy Board hears oral traditional evidence over Manitoba-Minnesota transmission line

Manitoba-Minnesota Transmission Line connects Bipole III to Minnesota, raising export capacity, as NEB hearings weigh Indigenous rights, treaty obligations, environmental assessment, cumulative effects, and cross-border hydroelectric infrastructure impacts, land access, socio-economic concerns, and regulatory review.

 

Key Points

A cross-border hydro line linking Manitoba to Minnesota under review on Indigenous rights and environment concerns.

✅ Connects Bipole III to Minnesota to boost exports

✅ NEB hearings include Indigenous rights and treaty issues

✅ Environmental and access impacts debated in regulatory review

 

Concerned Indigenous groups asked the National Energy Board this week to take into consideration existing and future impacts and treaty rights, which have prompted a halt to Site C work elsewhere, when considering whether to OK a new hydro transmission line between Manitoba and Minnesota.

Friday was the last day of the oral traditional evidence hearings in Winnipeg on Manitoba Hydro's Manitoba-Minnesota Transmission project.

The international project will connect Manitoba Hydro's Bipole III transmission line to Minnesota and increase the province's electricity export capacity to 3185 MW from 2300 MW.

During the hearings Indigenous groups brought forward concerns and evidence of environmental degradation, echoing Site C dam opponents in other regions, and restricted access to traditional lands.

Ramona Neckoway, a member of the Nelson House First Nation, talked about her concern about the scope of Manitoba Hydro's application to the NEB.

"It's only concerned with a narrow 213 km corridor and thus it erases the histories, socio-economic impacts and the environmental degradation attached to this energy source," said Neckoway.

Prior to the hearings the board stated it did not intend to assess the environmental and socio-economic impacts of upstream or downstream facilities associated with electricity production, even as a utilities watchdog on Site C stability raised questions elsewhere.

However, the board did hear evidence from upstream and downstream affected communities despite objection from Manitoba Hydro lawyers.

"Manitoba Hydro objected to us being here, saying that we are irrelevant, but we are not irrelevant," said Elder Tommy Monias from Cross Lake First Nation.

Manitoba Hydro representative Bruce Owen said, "We respect the NEB hearing process and look forward to the input of all interested parties."

The hearings provided a rare opportunity for First Nations communities, similar to Ontario First Nations urging action, to voice their concerns about the line on a federal level.

"One of the hopes is that this project can't be built until a system-wide assessment is made," said Dr. Peter Kulchyski, an expert witness for the southern chiefs organization and professor of Native Studies at the University of Manitoba.

 

Hearings continue

The line is already under construction on the American side of the border as the NEB public hearings continue until June 22 with cross examinations and final arguments from Manitoba Hydro and intervenor groups.

The NEB's final decision on the Manitoba-Minnesota transmission line, amid an energy board delay recommendation, will be made before March 2019.

Berlin urged to remove barriers to PV

Germany Solar Cap Removal would accelerate photovoltaics, storage, and renewables, replacing coal and nuclear during phaseout with 10GW per year toward 162GW by 2030, boosting grid resilience, O&M jobs, and domestic clean energy growth.

 

Key Points

A policy change to scrap the 52GW limit, enabling 10GW/year PV and storage to replace coal and nuclear capacity.

✅ Scrap 52GW cap to prevent post-2020 market slump

✅ Add 10GW PV annually; scale residential, commercial, grid storage

✅ Create jobs in planning, installation, and O&M through 2030

 

The German Solar Association (BSW) has called on the government to remove barriers to the development of new solar power capacity in Germany and storage capacity needed to replace coal and nuclear generation that is being phased out.

A 52GW cap should be scrapped, otherwise there is a risk that a market slump will occur in the solar industry after 2020, BSW said, especially as U.S. solar expansion plans signal accelerating global demand.

BSW managing director Carsten Körnig said: “Time is running out, and further delays are irresponsible. The 52GW mark will already be reached within a few months.”
A new report from BSW, in cooperation with Bonn-based marketing and social research company EuPD Research and The smarter E Europe initiative, said 10GW a year is needed as well as an increase in battery storage capacity.

This would lead to cumulative photovoltaic capacity of 162GW and 15GW residential, commercial and grid storage systems by 2030, in line with global renewable records being set, leading to new job opportunities.

The number of jobs in the domestic photovoltaic and storage industries could increase to 78,000 by the end of the next decade from today’s level of 26,400, aligning with forecasts of wind and solar reaching 50% by mid-century, said 'The Energy Transition in the Context of the Nuclear and Coal Phaseout – Perspectives in the Electricity Market to 2040' study.

Job growth would take place for the most part in the fields of planning, installation and operations and maintenance of PV systems, as solar uptake in Poland increases, the report said.

In maintenance alone, employment would increase from 9,200 to 26,000, with additional opened up by tapping into the market potential of medium- to long-term storage systems, alongside changing electricity prices in Northern Europe that favor flexibility, it said.

The report added that industry revenue could grow from €5bn to €12.5bn in the coming decade.

The report was supported by BayWa Re E3/DC, Fronius, Goldbeck Solar, IBC Solar, Panasonic, Sharp, Siemens, Sonnen, Suntech, Tesvolt and Varta.

Manitoba Hydro's burgeoning debt surpasses $19 billion

Manitoba Hydro Debt Load surges past $19.2B as the Crown corporation faces shrinking net income, restructuring costs, and PUB rate decisions, driven by Bipole III, Keeyask construction, aging infrastructure, and rising interest rate risks.

 

Key Points

Manitoba Hydro Debt Load refers to the utility's escalating borrowings exceeding $19B, pressuring rates and finances.

✅ Debt rose to $19.2B; projected near $25B within five years.

✅ Major drivers: Bipole III, Keeyask, aging assets, restructuring.

✅ Rate hikes sought; PUB approved 3.6% vs 7.9% request.

 

Manitoba Hydro's debt load now exceeds $19 billion as the provincial Crown corporation grapples with a shrinking net income amid ongoing efforts to slay costs.

The utility's annual report, to be released publicly on Tuesday, also shows its total consolidated net income slumped from $71 million in 2016-2017 to $37 million in the last fiscal year, mirroring a Hydro One profit drop as electricity revenue fell.

It said efforts to restructure the utility and reduce costs are partly to blame for the $34 million drop in year-over-year income.

These earnings come nowhere close, however, to alleviating Hydro's long-term debt problem, a dynamic also seen in a BC Hydro deferred costs report about customer exposure. The figure is pegged at $19.2 billion this fiscal year, up from $16.1 billion the previous year and $14.2 billion in 2016.

The utility projects its debt will grow to about $25 billion in the next five years. Its largest expenses include finishing the Bipole III line, working on the Keeyask Generating System that is halfway done and rebuilding aging wood poles and substations, the report said.

"This level of debt increases the potential financial exposure from risks facing the corporation and is a concern for both

the corporation and our customers who may be exposed to higher rate increases in the event of rising interest rates, a prolonged drought or a major system failure," outgoing president and CEO Kelvin Shepherd wrote.

The income drop is primarily a result of the $50 million spent in the form of restructuring charges associated with the utility's efforts to streamline the organization and drive down costs, amid NDP criticism of Hydro changes related to government policy.

Those efforts included the implementation of buyouts for employees through what the utility dubbed its "voluntary departure program."

Among the changes, Manitoba Hydro reduced its workforce by 800 employees, which is expected to save the utility over $90 million per year. It also reduced its management positions by 26 per cent, a Monday news release said, while Hydro One leadership upheaval in Ontario drove its shares down during comparable governance turmoil.

To improve its financial situation, Hydro has applied for rate increases, even as the Consumers Coalition pushes to have the proposal rejected. The Public Utilities Board offered a 3.6 per cent average rate hike, instead of the 7.9 per cent jump the utility asked for.

In May, when the PUB rendered its decision, it made several recommendations as an alternative to raising rates, including receiving a share of carbon tax revenue and asking the government to help pay for Bipole III.

Hydro is projecting a net income of $70 million for 2018-2019, which includes the impact of the recent rate increase. That total reflects an approximately 20 per cent reduction in net income from 2017-18 after restructuring costs are calculated.
