As energy security becomes increasingly important, the Army's new laboratory near Detroit is expected to help build green technologies to alleviate dependence on foreign imported fossil fuels. At an event held at the research complex today, researchers unveiled plans to develop technologies such as fuel cells and hybrid systems to be used for combat vehicles.

In a research competition, federal officials aim to produce enough renewable energy on military bases to equal the output of three nuclear plants by 2025. The Pentagon has previously announced that it intends to meet a fourth of its energy needs from renewables by then as well.

Under another competition, the Energy Department is spending $30 million to fund the research for developing new types of batteries to reduce the needs for refueling in combat areas.

The Army's Ground Systems Power and Energy Laboratory includes eight separate labs for testing electrical systems, heating and cooling components, fuel cells, hybrid electric powertrains and advanced batteries. The labs allow the researchers to create a variety of environmental conditions to test such technologies appropriately.

The technologies to be developed are expected to help save lives in the field in Iraq and Afghanistan, where many are killed merely from hauling fuel to battle areas. Some of those innovations, of course, are also expected to spill over into the commercial market.

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
