Natural gas is being hailed as the next great thing to take over now that the world is coming to its senses about the dwindling oil supply. With shale gas reserves offering abundant supplies, it seems natural gas will offer a solution—all be it a temporary one—to the electricity generation and transportation sectors. Now, top car manufacturers like Honda and GM are taking natural gas seriously as an alternative to traditional petroleum fuel, and are preparing to launch natural gas powered cars and trucks within the next few years.

Thought electric cars were the next transport fad? Well they certainly will be gaining in popularity, but natural gas cars are far cheaper to produce than lithium-ion powered electric vehicles. For example, the Honda Civic GX CNG will run on compressed natural gas and cost just $25,490 compared to the all-electric Chevy Volt, which will cost $41,000, or the $32,000 Nissan Leaf (both considered the most affordable of commercial electric cars). The Civic GX CNG is due for release next year in all 50 U.S. states.

GM’s lineup of natural gas truck and van models has been on the market since last year. Chrysler is also gearing up for a natural gas push, and with parent company Fiat already manufacturing and selling natural gas vehicles in Europe and South America it should be a fairly simple transition.

Like electric vehicles, natural gas vehicles may soon get some help from the U.S. government. A newly introduced congressional Natural Gas Bill has already gained 154 sponsors and if passed will offer credits for the purchase of natural gas vehicles, similar to what is being done with electric cars currently.

While electric vehicles will become more ubiquitous, it seems that natural gas will be a top competitor in the coming decade. However, believe it or not, as far as infrastructure is concerned, electric charging stations are more prevalent than compressed natural gas fueling stations. California for example has 448 electric vehicle charging stations, but only 217 natural gas stations. The nice thing about natural gas, like electricity, is that most homes already have it for heating and cooking needs, and home fueling stations are likely to become popular with natural gas vehicle owners.

So what we are likely to see is a massive development of electric infrastructure side-by-side with natural gas infrastructure. This is actually a good thing for various reasons. Electric charging stations rely on grid electricity to operate, and there are several exciting renewable electricity generation methods—such as solar, wind, geothermal, etc.—that will be able to consistently provide electricity as they develop.

With natural gas, however, the supply that can be extracted from the Earth is limited, and you run into the same supply problems as with oil. But there are different methods of collecting biogas—the gas released from biological organisms—that could continue to feed natural gas infrastructure. In Sweden for example, the entrails of commercially butchered livestock are processed and methane collected to power the country’s transportation system. These are the kinds of energy solutions that will get us through the 21st century, and a gas/grid infrastructure combo is an excellent way forward!

Major move forward for UK’s nascent marine energy sector

The UK’s nascent marine energy sector starts exporting electricity to the grid as the most powerful tidal turbine in the world begins to generate power

Although the industry is small and the technologies are limited, marine-based energy systems look to be taking off as “the world’s most powerful tidal turbine” begins grid-connected power generation at the European Marine Energy Centre

At around 74 metres long, the turbine single-handedly holds the potential to supply the annual electricity demand to approximately 2,000 homes within the UK and offset 2,200 tonnes of CO2 per year.

Orbital Marine Power, a privately held Scottish-based company, announced the turbine is set to operate for around 15 years in the waters surrounding Orkney, Scotland, where the 2-megawatt O2 turbine weighing around 680 metric tons will be linked to a local on-land electricity network via a subsea cable. 

How optimistic is the outlook for the UK’s turbine bid?

Described as a “major milestone for O2” by CEO of Orbital Marine Power Andrew Scott, the turbine will also supply additional power to generate ‘green hydrogen’ through the use of a land-based electrolyser in the hopes it will demonstrate the “decarbonisation of wider energy requirements.” 

“Our vision is that this project is the trigger to the harnessing of tidal stream resources around the world to play a role in tackling climate change whilst creating a new, low-carbon industrial sector,” says Scott in a statement. 

The Scottish Government has awarded £3.4 million through the Saltire Tidal Energy Challenge Fund to support the project’s construction, while public lenders also contributed to the financial requirements of the tidal turbine through the ethical investment platform Abundance Investment.

“The deployment of Orbital Marine Power’s O2, the world’s most powerful tidal turbine, is a proud moment for Scotland and a significant milestone in our journey to net zero,” says Michael Matheson, the Cabinet Secretary for Net-Zero, Energy and Transport for the Scottish Government. 

“With our abundant natural resources, expertise and ambition, Scotland is ideally placed to harness the enormous global market for marine energy whilst helping deliver a net-zero economy.

“That’s why the Scottish Government has consistently supported the marine energy sector for over 10 years.”

However, Orbital Marine CEO Scott believes there’s potential to commercialise the technology being used in the project with the prospect of working towards more efficient and advanced marine energy projects in the future. 

We believe pioneering our vision in the UK can deliver on a broad spectrum of political initiatives across net-zero, levelling up and building back better at the same time as demonstrating global leadership in the area of low carbon innovation that is essential to creating a more sustainable future for the generations to come.” 

The UK’s growing marine energy endeavours

This latest tidal turbine project isn’t a first for marine energy in the UK. The Port of London Authority permitted the River Thames to become a temporary home for trials into tidal energy technology and, more recently, a research project spanning the course of a year is set to focus on the potential tidal, wave, and floating wind technology holds for the future efficiency of renewable energy. The research is due to take place off of the Southwest coast of England on the Isles of Scilly
