As we head into the new year, Energy Digital will be posting some of best stories from 2011 all week. Happy Holidays to all of our readers!

Over ten years ago, it was General Motors (GM) to become the first major automaker to mass-produce electric vehicles. In the late 90s, GM's EV1 was an electric car with huge potential, with support from the California Air Resource Board (CARB) and waiting lists that outpaced production. When GM decided the cars were not profitable, they literally crushed virtually every EV1 ever made, leaving only a few non-drivable models for museums to reminisce on the days fully electric, efficient cars were once a reality.

The controversial discontinuation of the EV1s broke the hearts of many consumers and EV1 advocates, exemplified in the documentary Who Killed the Electric Car? The director, Chris Paine, now has a new film called Revenge of the Electric Car, following the global resurgence of electric cars mainly from Nissan, GM, and Tesla.

“Ten years after they killed the electric car, it's back,” boldly reads the introduction to the film's trailer:

The truth is, the first major fleet of electric cars hitting the road posed a major threat to the oil industry. A decade later, the green economy has more clout. The oil industry is approaching a tighter market and consumer demand for alternatives is higher. With the same intensity automakers once shut down their premier electric vehicles, they are now racing to build the world's greenest cars.

November's issue of Energy Digital has gone live!

Hype around GM's leadership in electric vehicle (EV) rollout has lagged behind. GM's 2010 Chevy Volt introduced a semi-electric car, capitalizing on the consumer fears of running out of battery and getting stranded, but less than 4,000 actually sold. GM's stock has gone down over 30 percent since its IPO last November, with expectations of the Volt failing to hit targets.

As of October, GM announced it would officially launch a fully electric vehicle domestically in the next year. As part of a plan to expand the series of electric cars, the Chevy Spark is expected to become the first all-electric vehicle that will rival the Nissan LEAF, the current top selling electric vehicle in the U.S. Nissan sold seven times more of its Nissan LEAF electric cars than GM sold of its Chevy Volts. Tending to consumer trends, GM pursues a fully electric car in the US in hopes to seize the title of “greenest automaker” from its competitors.

GM's fully electric Chevy Spark:

Set to be produced at a plant in White Marsh, Maryland, the Spark's 85 kW, 114 hp motor will use nonophosphate lithium-ion batteries supplied by A123 Systems and have permanent magnet and induction motors. GM expects other vehicles in the future to run on propulsion motors, while nine of its vehicles already use electric motors as part of the propulsion system. According to GM's Chief Engineer Pete Savagian, each of its electric motors has three long lives of 200k miles each.

“We’ve spent the past few years highlighting our in-house battery capability, which will play a significant role as one of our core competencies going forward,” said Larry Nitz, GM executive director of Vehicle Electrification Engineering. “Electric motor development and manufacturing is another area of expertise we’ll need as we expand vehicle electrification technologies to address the needs of our customers around the world.”

Until recently, electric cars have been held back in the US market due to a lack of choices, high price tags, poor infrastructure for charging stations and low fuel prices. But as the industry faces requirements to produce more fuel-efficient cars by 2025, the competition to build the greenest, sexiest electric cars has stimulated growth and innovation between competitors.

"We welcome competitors into the market," Mark Perry, director of product planning for Nissan Americas, told Reuters. "We're glad that GM has decided to go pure electric. This brings further validity to the segment."

Under GM Chief Executive Daniel Akerson, GM's fourth CEO since 2009, the company has pursued electric vehicles aggressively and is using the new Spark as a way to recoup some of the lost investment in the Volt. By mass-producing electric vehicle technology, as it did in the 90s, the cost of the cars would make them a fraction of the cost of the $40,000 Volt.

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
